We study bi-antisymmetric tensor quantum field theories with O(N1)×O(N2) symmetry. Working in 4− dimensions we calculate the beta functions up to second order in the coupling constants and analyze in detail the Renormalization Group (RG) flow and its fixed points. We allow N1 and N2 to assume general real values and treat them as bifurcation parameters. In studying the behavior of these models in a non-unitary regime in the space of N1 and N2 we find a point where a zero-Hopf bifurcation occurs. In the vicinity of this point, we provide analytical and numerical evidence for the existence of Shilnikov homoclinic orbits, which induce chaotic behavior in the RG flow of a subset of nearby theories. As a simple warm-up example for the study of chaotic RG flows, we also review the non-hermitian Ising chain and show how for special complex values of the coupling constant, its RG transformations are equivalent to the Bernoulli map.

The Foundation of the Opera as Art Form.
In the history of opera as an art form, opera had a few false starts -- first as merely an application of an intellectual reconstruction of the dramatic principles underlying Greek tragedy, and next as a genre serving important nonartistic purposes, lacking in intellectual, musical, and artistic content. In the development of the current operatic conventions, composer Jean-Baptiste Lully created an art form in seventeenth-century France that met the demands of the court, the bourgeoisie, and the intellectuals. Richard Wagner then attempted to adapt the opera to conform to prevailing requirements of artistic autonomy. As were other art forms, the operatic are form was confronted with the gradual rise of a dualistic structure in the artistic field with commercial art at one end and avant-garde at the other. After this period of turbulence, opera as a serious art form was restored. 73 References. Adapted from the source document.

Sinusitis is one of the most common conditions. The aetiology of sinusitis has not been fully discovered; however, viruses and bacteria are usually the dominant causes. The chief symptoms include nasal congestion, profuse nasal discharge and a compromised sense of smell. Inflammation of any sinus can be the source of complications. Complications develop usually as a result of exacerbation of chronic sinusitis. Sinusitis may result in inflammation spreading inside the cranium and to the orbital area and in the development of osteomyelitis or superior sagittal sinus thrombosis. Due to the anatomical location and proximity of important structures, sphenoid sinusitis may lead to meningitis or subdural empyemas, temporal lobe abscesses and cavernous sinus thrombosis. Fungal sinusitis is very dangerous since it is characterised by a rapid course often complicated by intracranial and orbital spread. Invasive fungal paranasal sinusitis with orbital complications is a life-threatening emergency. If there is concern about possible orbital or intracranial complications of sinusitis or if there is no improvement after initial empirical therapy, the use of diagnostic imaging is necessary, including computed tomography and magnetic resonance imaging. Early diagnosis of sinusitis and multidisciplinary management involving a combination of antibiotic therapy and surgical treatment, including neurosurgery and maxillofacial procedures can be effective in the prevention of complications and may significantly reduce morbidity and mortality.

Objectives: The aim of this study was to examine the effects of electroacupuncture(EA) at the H(7) (Shinmun) on normal humans using power spectral analysis. Methods: EEG power spectrum exhibit site-specific and state-related differences in specific frequency bands. In this study, power spectrum was used as a measure of complexity. 32 channel EEG study was carried out in 9 subjects (9 males; age=25,8 years). Results: In alpha band, the power values at Fp2 channels(p<0.05) during the H7-acupoint treatment significantly were decreased. In beta band, the power values at Fp1, Fp2 channels(p<0.05) during the H7-acupoint treatment significantly were decreased. In delta and theta band, the power values at the H7-acupoint treatment significantly was increased than the before-acupuncture treatment. Conclusions: This results suggest that electroacupuncture at the H7 is significantly in beta band of EEG.


We show that a Cramér–Wold device holds for infinite divisibility of Zd-valued distributions, i.e. that the distribution of a Zd-valued random vector X is infinitely divisible if and only if the distribution of aTX is infinitely divisible for all a ∈ Rd, and that this in turn is equivalent to infinite divisibility of the distribution of aTX for all a ∈ N0. A key tool for proving this is a Lévy–Khintchine type representation with a signed Lévy measure for the characteristic function of a Zd-valued distribution, provided the characteristic function is zero-free.

High pressure/High temperature operations remain a high challenge for the industry as deeper reservoir operations are pursued around the globe. In addition to deeper depths, an increasing number of wells are still being drilled and completed in much more hostile down-hole environments. Though high pressure/high temperature wells have always presented drilling challenges, their operations continued to remain very high as the vast reserves of hydrocarbon promised to bridge the gap between demand and supply for energy. The world's energy demand is rising and favorable economics have allowed oil companies to continue to prospect and drill in these more challenging areas that are actually prone to high pressures / high temperatures than ever before. This paper addresses some of the challenges relative to cement slurry designs that requires careful engineering practices and needs proper cementing operations and optimization. It presents a simulation study using retarder sensitivity to select thickening time, optimize cement properties and also predict the subsequent HPHT sensitivity on cement slurries. The results showed that the modified Magnesium Oxide(mixture of water-glass and magnesium oxide) was best for slurry design for high pressure/high temperature which gave tighter matrix of cement paste. The application of retarder reduced the thickening time but the Water-Glass Solution improved the Magnesium Oxide cement thickening time, indicating that thickening time was dependent on time of exposure and on temperature. The rheological properties of the slurry showed that at HPHT, there were decreases in plastic viscosity, gel strength and the yield point. The study therefore determined one of the best cement slurry design practices for different down-hole applications in HPHT wells. KEY WORDS : Cement slurry, Thickening Time, Modified magnium Oxide,High temperature/High Pressure

Traumatic injuries and fractures resulting from falls by elderly individuals have become a major issue for the government bodies responsible for health, medical care, and social welfare because they markedly reduce the individualsrsquo ability to engage in activities of daily living. Major causes of such falls by elderly individuals are decreased balance ability and impairment associated with aging. Proprioceptive information obtained by movement of the lower extremity muscles and joints are important for maintaining balance. However, there have been very few studies concerned with further quantifying lower extremity proprioceptive sense, which for elderly individuals is important for maintaining standing balance. The objectives of this study were to develop the first device to quantitatively evaluate changes in the proprioceptive threshold (motion sense and joint position sense) that is associated with changes in the angle of the ankle during standing and, based on this evaluation, establish methods of evaluating and training joint sense that are needed to improve balance ability by using a new device.

 The subjects were five elderly individuals (mean 71.4 years) and seven young individuals (mean 20.6 years) who were not proficient at sports. A new device was used to evaluate the motion sense and the joint position sense during plantar flexion, dorsiflexion, inversion, and eversion of the ankle with the individual in the standing position. The device was shown to be capable of measuring ankle proprioceptive sense during standing to 1 degree of accuracy. The subject stood with their dominant foot on the motor-driven foot plate of the device. Next, the motor-driven plate was inclined at a specified angular velocity, and the subject was instructed to stop the plate by pressing a button near their hand when they felt that the inclination angle matched that of the non-dominant leg. Four movement directions were used for the ankle: dorsiflexion, plantar flexion, eversion, and inversion. The two dorsiflexion angles used were 5 and 10 degrees the three plantar flexion angles were 5, 10, and 15 degrees the two eversion angles were 5 and 10 degrees and the three inversion angles were 5, 10, and 15 degrees. The two angular velocities used were 1 and 2 degrees/sec. For the analysis, the inclination angle of the non-dominant foot was used as the set angle, and the angle at which the subject stopped the plate was used as the stop angle. The error (| set angle - stop angle |) was the test parameter. The minimum error value obtained in the two trials was recorded.nbsp


A VALUABLE contribution by Professor Gardner to the " Catalogue of the Greek Coins in the British Museum," published by the Trustees under the editorship of the Keeper of Coins. The volume deals with the entire Peloponnesus, Corinth excluded. The description of the coins occupies 203 pages and there are 37 plates of autotype reproductions of the specimens. The usual full Indexes of Types, Inscriptions, &c. accompany the book. Brief but interesting foot-notes are added to many of the descriptions of the types, and numerous references are given to Pausanias, whose Periegesis so often illustrates and is illustrated by the coinages of Peloponnesus (Compare the Numismatic Commentary on Pausanias by ImhoofBlumer and P. Gardner). The introduction (pp. i.-lxii.) gives a masterly sketch of Peloponnesian numismatics. The first section of this deals chiefly with the monetary standards employed in the Peninsula and some of its chief results may be summarized as follows. The earliest regular issue of money in the Peloponnese cannot be placed before B-C. 500. During the two centuries preceding this date the want of a native currency was no doubt supplied by the tortoise coins of Aegina. Aegae, Sicyon, Elis, Cephallenia, Zacynthus, Argos, and the Arcadian towns Heraea, Cleitor and Psophis begin to strike coins before B.C. 471, and " towards the end of the fifth century all towns of any importance in the Peninsula have mints." Bronze coins first appear about B.C. 400. Gold coins are extremely rare and are considered by Professor Gardner to be " in no case of quite unimpeachable authenticity."


Anne led a health education initiative from the outpatient department of Dolgellau Hospital in Wales to address inequalities in men's health. Her research identified barriers the rural community experienced in accessing health education. With her team she consulted individuals and groups to find acceptable and accessible ways to engage men. Plans were developed with colleges, workplaces and GPs. Initiatives include prostate symptom drop-in clinics and awareness sessions for community groups in pubs. There is a healthy heart programme offering one-to-one support. Testicular cancer awareness sessions are provided in schools and colleges, and there are sun awareness sessions for farmers at cattle markets.


Type III IFNs (IFN-λ/IL-28/29) are cytokines with type I IFN-like antiviral activities, which remain poorly characterized. We herein show that most cell types expressed both types I and III IFNs after TLR stimulation or virus infection, whereas the ability of cells to respond to IFN-λ was restricted to a narrow subset of cells, including plasmacytoid dendritic cells and epithelial cells. To examine the role of type III IFN in antiviral defense, we generated IL-28Rα-deficient mice. These mice were indistinguishable from wild-type mice with respect to clearance of a panel of different viruses, whereas mice lacking the type I IFN receptor (IFNAR−/−) were significantly impaired. However, the strong antiviral activity evoked by treatment of mice with TLR3 or TLR9 agonists was significantly reduced in both IL-28RA−/− and IFNAR−/− mice. The type I IFN receptor system has been shown to mediate positive feedback on IFN-αβ expression, and we found that the type I IFN receptor system also mediates positive feedback on IFN-λ expression, whereas IL-28Rα signaling does not provide feedback on either type I or type III IFN expression in vivo. Finally, using bone-marrow chimeric mice we showed that TLR-activated antiviral defense requires expression of IL-28Rα only on nonhemopoietic cells. In this compartment, epithelial cells responded to IFN-λ and directly restricted virus replication. Our data suggest type III IFN to target a specific subset of cells and to contribute to the antiviral response evoked by TLRs.


The exploratory descriptive study, with qualitative approach, was carried out in a public hospital in the south of Brazil, with the objective to identify situations of comfort and discomfort lived by the accompanying person of a chronic ill relative during hospitalization. The data were collected through a semi-structured interview with sixteen family members. The thematic analysis was used, and from that two themes emerged: the situations that generate comfort lived by the family companions and situations which generate discomfort lived by the family companions. The companions identified the situations that generate comfort by interactions with the team of professionals and the other companions; by the clinical improvement of the sick person; and by the closeness to the ill individual. The situations which generate discomfort were associated to the experiencing illness at the hospital; to the physical discomfort of the companion and to the financial and professional aspects. It is understood that the situations of discomfort reported by the companions result in implications for the hospital as an institution and for the health professionals. Therefore, there is a need to invest in a specific policy of attendance to the companion in order to minimize the situations of discomfort, and intensify the comfort situations.

We demonstrate a software system that runs on the Symbian smartphone platform, and allows a group to capture the essence of a face-to-face meeting or remote conference call in a decentralized manner. We show how the users set up a meeting, record elements from the meeting, and are able to continue the collaboration after the original meeting has ended. We show how the information collected during the meeting can be used by members to analyze the collective impression of the meeting, as well view consensus or differences of opinions.


Inverters are widely used as electrical drive systems in many industrial applications. The inverter IGBT switch open-circuit fault; object of our study; is one type of the inverter faults that attracts the attention of many researchers. In this paper an open-circuit fault detection technique is proposed using the artificial neural network (ANN) aided by the Clarke transform. The technique is presented according to two approaches. The first approach calculates the Clarke stator currents and other quantities such as the intervals fault angles α and the trajectory surface S. Once all these quantities are obtained, they are then introduced to the ANN structure for the learning process; the output obtained from the ANN corresponds to the exact angle related to the inverter IGBT switch open-circuit fault. The second approach follows exactly the same calculation steps as the first approach except that in this case all the computation is performed within the ANN architecture. To illustrate the effectiveness of the technique and validate the results, some experimental works are conducted using a three-phase voltage inverter fed induction motor.

This work involves methanol-to-propylene (MTP) conversion over aluminosilicate MFI (ZSM-5), borosilicate MFI (B-ZSM-5), and all-silica MFI (Silicate-1). Both B-ZSM-5 and Silicate-1 were inactive in MTP reaction. However, extruded Silicate-1 sample prepared by extrusion with Al2O3 binder, followed by acid washing treatment, displayed a rapid increase in methanol conversion in the initial 30 h time on stream (TOS), and then retained 99% methanol conversion, higher propylene selectivity (52.2%), and higher propylene/ethylene ratio (11.3) for 400 h TOS. Silicate-1 modified with AlCl3 or Al(NO3)3 showed similar catalytic performance as the extruded samples. Several AlCl3-modified Silicate-1 samples after various TOS values were regenerated and characterized by NH3-termperature-programmed desorption (TPD), Fourier transform infrared (FT-IR) spectroscopy, and 27Al magic angle spinning nuclear magnetic responance (MAS NMR). The results point to continuous aluminum insertion into Silicate-1 framework during reacti...


In the previous study it has been shown that the introduction of acid groups into the rayon fibers is not effective to increase the fastness to washing.In this study, the effects of hydrophobic groups on the fastness were discussed thermodynami-cally. The effects of the hydrophobic groups and the acid groups when they were coexisting were also discussed similarly.The results obtained are as follows:(1) The affinities and enthalpy changes in the partition (C) type adsorption of the dyes are increased with the hydrophobic group content in the rayon fiber.(2) When the hydrophobic groups and the acid groups coexist, the affinities in the Langmuir's type adsorption of the dye are increased by 2_??_3kcal/mol and the affinities in the C type adsorption of dye are also increased slightly in comparison with the values obtained when only the hydrophobic groups or the acid groups are present.

For a class of high order nonlinear systems with structure and non structure uncertainty which are repeatable in a finite time interval, an adaptive iterative learning control algorithm is proposed. By combining the Backstepping approach, the system replacement technique with the parameter regrouping technique, which can handle the iteration-varying control direction and iteration-varying trajectory tracking problem. A differential-difference type adaptive law and an adaptive iterative learning controller are constructed to ensure the asymptotic convergence of tracking error in the sense of square error norm on the finite interval,by introducing a Lyapunov function, a sufficient condition of the convergence of the method is given. A simulation example illustrates the feasibility of the proposed method.


An easy and rapid staphylococcal coagulation test is described for detection of bacteria, covered with antibodies in urine of patients with chronic pyelonephritis as an additional index of the etiological role of the isolated microorganisms and localization of the pathological process. Inactivated and stabilized protein A containing strain S. aureus Cowan's (SSM 2352) was used. The coagulation test is negative in infectious processes of the lower segments of urinary system and bacterial contamination of urine.


This paper presents an application of the novel evolutionary algorithm for assessing an economic power system operation throughout a combined economic and emission dispatch problem required by various technical limitations. Moreover, this problem considers pollutant production and fuel consumption problems for covering environmental protection and fuel usage aspects as a constrained objective function. Running out simulations show, minimum costs depend on various weighting factors implemented in the defined problem. Reducing the total fuel cost focused on the dispatching priority and the pollutant target based on the emission production have different implications as its contribution on the economic operation. The increased power demand leads to generated powers, costs and emission discharges associated with its parameters and schedules.


The recent images published by Akita et al. [1] showing intracardiac calcified masses at the level of the mitral annulus represent a specific stage in the spectrum of an evolving disease. 'Mitral annulus calcification (MAC) may appear under different forms depending from its evolution stage: mitral annulus calcification; homogeneous calcified mass of the mitral valve; liquefaction necrosis of the mass; with reduction or stability of the mass dimension' during follow-up [2]. This condition may sometimes alter mitral valve function, provoking a transvalvular gradient or regurgitation by a distortion of the valvular apparatus [3]. However, the presence of calcified mitral annular masses protruding inside the left atrium should not be considered per se as an indication for surgery in the absence of an altered valve function. Surgery should not be recommended for the presence of only calcified masses at the level of the mitral annulus. It is true that pathologies of a different nature may affect the annulus or the nearby tissues. However, several imaging modalities [ultrasound, computed tomography scan and cardiac magnetic resonance (CMR)] may currently help to specify the nature of those calcified masses [2– 4]. Different pathologies, such as soft tissue calcified sarcomas, calcified echinococcoccus cysts, cardiac osteocondromas and cardiac calcified amorphous tumours (CAT), should be included in the differential diagnosis [2]. However, specific imaging signs may help to reach a presumptive diagnosis. Soft tissue sarcomas are usually large and invasive masses with calcifications mostly involving only part of the necrotic tumour [4]. In echinococcal cysts, calcifications are classically peripheral. Primitive osteosarcomas can show massive calcification, but they usually grow rapidly [4]. If liquefaction necrosis occurs in MAC, and this is usually associated with a reduced mass dimension during the follow-up and with a benign prognosis [2, 5]. A cardiac CAT, showing a mass (thrombi, infections or infestations) with a mix of calcifications and inflammatory infiltrates, should also be considered in the differential diagnosis [6]. In conclusion, in patients with MAC, surgery should be indicated by the gradient across the valve or by the grade of regurgitation. In cases without abnormal valve function, conservative management may be effective even with large masses [2]. Multimodality imaging studies would help to specify their nature. Indications for surgery should be carefully weighed, in consideration also of the higher incidence of MAC in patients with clinical or subclinical chronic renal failure, as in the reported case.


Abstract The compositions of air-formed passive films on ferritic stainless steel (SS) were modified by exposure in solutions containing CrO−2, MoO4−2, and WO4−2 ions. The steel samples prepared in this manner were investigated for their pitting resistance in 3% NaCl by measuring the pitting nucleation potential. Auger electron spectroscopy (AES) analyses of the prepared films were conducted, and a correlation was made between the films' compositions and their resistance to the Cl− ions.


Chipless radio frequency identification (RFID) tags are dummy, memoryless, with limited number of bits, very low backscattered power, and short reading range. Therefore, the existing RFID standards and protocols designed for the chipped RFID systems are not applicable for the chipless systems. Main objective of this contribution is to introduce a novel real‐world testbed for multi‐tag ultra‐wideband (UWB) chipless RFID system. In this testbed, a new Notch Position Modulation scheme is implemented as the first medium access control algorithm for handling the multi‐tag identification scenario of the frequency signature based chipless RFID tags. This intelligent Notch Position Modulation algorithm reduces the sensing and identification time and accordingly the overall system latency. The proposed protocol enables fetching the frequency signatures of the chipless RFID tags through the whole UWB range effectively. Moreover, an advanced signaling scheme is designed for the RFID reader in order to make the best use of the Federal Communications Commission UWB regulations for increasing the maximum transmitted power and the corresponding reading range. The signaling scheme, real‐time channel estimation, and clutter removal technique are implemented on the software defined radio platform in a heavily dense multipath indoor environment. Based on the medium access control protocol, the mitigation of the undesired environmental reflections as well as the interference between the chipless RFID tags is well demonstrated in the developed testbed.


Mapping vegetation in the tropics is of primary importance to assess its contribution to important ecosystem services. This implies to implement methods to capture the vegetation gradient that characterizes land cover in these regions. Linear Mixture Models have long been used to monitor this gradient. In the present study, we automatically unmixed six Landsat 8 images of a study area in the Republic of Congo. We then computed the weighted average fraction of mineral, vegetation and water/shadow classes for each pixel in order to produce an annual (nearly) cloud-free unmixed image. Finally this product is pre-classified into six semantic classes ranging from "very dark" to "very bright" classes to discriminate the vegetation gradient based on its visual appearance. Results indicate the ability of the approach to classify fine land cover classes while still keeping textural information of the raw image.


Nowadays,the positive mental health education is increasingly becoming the major forms of mental health education in colleges and universities,and many colleges and universities set the specific course on positive mental health education centering on happiness.However,the current situation of positive mental health education is far from satisfactory.A series of problems remain to be settled,for instance,issues concerning teachers' spreading the awareness and ideas of positive mental health,the cooperation between schools and the related associations,the objective of such education,the development of textbooks,and the content and the assessment of the related course.The solution of those problems helps to fundamentally implement positive mental health education in colleges and universities,enhance the teaching effect of the related courses,and furthermore increase the wellbeing of college students.


The process of developing a new brand includes establishing an identity that communicates its spirit. Our purpose is to describe the research that led to the development of the verbal and visual representations that communicate the new Fruits & Veggies—More Matters™ brand. Formative research to develop the slogan and logo included input from 1033 grocery shoppers who completed an online questionnaire. Reactions to the slogan alone included that it communicates general health benefits of fruits and vegetables (F/V)(41%), specific F/V (14%); people should eat more (13%). All benefits of F/V(e.g. health, energy, variety, well‐being, feel better) were recognized as important in driving decisions to eat/serve F/V. Three logos, presented in random order, showed the juggler ranked by 51% as communicating the qualities and benefits of F/V the best, especially 'providing energy' and 'making a person feel better'. When slogan and logo were viewed together, the slogan increased interest in eating more F/V 'extremely well' (27%), 'very well' (35%), and 'somewhat well' (28%). Reasons given included 'the health message of F/V' (29%); reminder value (11%), 'like logo and symbolism' (10%). Negative reactions included 'vague' (8%), 'not enough to change habits' (6%), 'boring' (3%) and 'not new info' (3%). The Fruits & Veggies—More Matters™ brand identity is relevant, inspiring, and serves as a platform for tailored messages.


A calibration‐based technique for real‐time measurement of pyruvate polarization by partial integral analysis of the doublet from the neighbouring J‐coupled carbon is presented. In vitro calibration data relating the C2 and C1 asymmetries to the instantaneous C1 and C2 polarizations, respectively, were acquired in blood. The feasibility of using the in vitro calibration data to determine the instantaneous in vivo C1 and C2 polarizations was demonstrated in the analysis of rat kidney and pig heart spectral data. An approach for incorporating this technique into in vivo protocols is proposed. Copyright © 2013 John Wiley & Sons, Ltd.


Although cloud network flows are similar to conventional network flows in many ways, there are some major differences in their statistical characteristics. However, due to the lack of adequate public datasets, the proponents of many existing cloud intrusion detection systems (IDS) have relied on the DARPA dataset which was obtained by simulating a conventional network environment. In the current thesis, we show empirically that the DARPA dataset by failing to meet important statistical characteristics of real-world cloud traffic data centers is inadequate for evaluating cloud IDS. We analyze, as an alternative, a new public dataset collected through cooperation between our lab and a non-profit cloud service provider, which contains benign data and a wide variety of attack data. Furthermore, we present a new hypervisor-based cloud IDS using an instance-oriented feature model and supervised machine learning techniques. We investigate 3 different classifiers: Logistic Regression (LR), Random Forest (RF), and Support Vector Machine (SVM) algorithms. Experimental evaluation on a diversified dataset yields a detection rate of 92.08% and a false-positive rate of 1.49% for the random forest, the best performing of the three classifiers.


Introduction While state-local corporate tax revenue has remained relatively constant for several decades, bringing in roughly five percent of revenue, some states have significantly increased their reliance on corporate taxes while others have relied less on that revenue source. The average state corporate tax rate – defined as collections divided by state income – has risen from 2.6 percent several decades ago to 4.4 percent today.


When the Supreme Court announced in Arizona v Fulminantel that the introduction of a coerced confession into evidence in criminal trials may be treated as "harmless error," critics attacked the decision as a crabbed reading of the Constitution's grand protections of the rights of the criminally accused. The Los Angeles Times reported that the Court "knocked down one of the pillars of constitutional law,"2 and complained that the decision "seriously eroded one of the Constitution's fundamental protections."3 Steven Shapiro, Associate Director of the American Civil Liberties Union, said that the case reflected the Rehnquist Court's increased willingness "to balance fundamental constitutional rights against the desire to preserve and uphold criminal convictions."4 Even Justice Stevens added to the chorus: "an extraordinarily aggressive Supreme Court has reached out to announce a host of new rules narrowing the federal Constitution's protection of individual liberties. The prosecutor's use of a coerced confession-no matter how vicious the police conduct may have been-may now constitute harmless error."' These criticisms reflect the now-predominant understanding of the harmless error rule as being a doctrine of constitutional law. They each assume that the Supreme Court decisions that expand the scope of harmless error analysis by the same token contract the sweep of constitutional rights.

High dynamic range imaging is central in application fields like surveillance, intelligent transportation and advanced driving assistance systems. In some scenarios, methods for dynamic range extension based on multiple captures have shown limitations in apprehending the dynamics of the scene. Artifacts appear that can put at risk the correct segmentation of objects in the image. We have developed several techniques for the on-chip implementation of single-exposure extension of the dynamic range. We work on the upper extreme of the range, i. e. administering the available full-well capacity. Parameters are adapted pixel-wise in order to accommodate a high intra-scene range of illuminations.


An augmented transistor model where a three-terminal device is automatically biased internally is presented. A duplicate of the signal transistor is used to solve the bias equations. This model makes it convenient to compare transistor circuit topologies by simulation.


Abstract Attempting to create an image, a figure adequate to the critic's discourse on the law, this paper develops a series of variations on the notion of the critic's love for the law, responding to the comments of Peter Goodrich and Oren Ben-Dor, both of whom criticised critique for not breaking with law, for remaining internal to law. Taking their positions perhaps more literally than intended, Goodrich's "love" is considered as an instance of Freud's analysis of what motivates some men's object choice in love, which is then read allegorically, and Ben-Dor's "anticipation" is considered as a version of the story of Tristan and Iseult, as interpreted by de Rougemont. Both are revealed to be instances of mis-identification, with, however, the critic's delusion redeemed as nobler than that of the spouse, perhaps even a more profound knowledge. The critic loves, the apologetic espouses. The critic's work is not a useless passion.


. Efficiency of neurometabolic therapy was studied in patients with acute ischemic stroke by determining the level of neuron-specific enolase and the dynamics of cognitive status. It is proved that the combination of drugs that affects the cholinergic system accelerated recovery of consciousness, reduced neurologic deficit and maintained cognitive status.


Introduction: Diabetes mellitus (DM) is a chronic disease that occurs because the pancreas cannot produce enough insulin or the body cannot effectively use the insulin produced by the pancreas. There are 4 ways to maintain blood glucose levels, namely; pharmacological therapy, nutritional therapy, diabetes self management education, and physical activity. Walking exercise is the most often described as the modalities of physical activity to improve health.
Objective: The research objective was to determine the effect of walking physical activity on blood sugar levels in diabetes mellitus patients in the work area of the Cianjur Kota Health Center in 2021.
Method: This study used a design quasi-experimental with an approach one-group pretest-posttest design. The population of this study was all 620 people with diabetes mellitus who were taken using a simple random sampling technique, which was 17 respondents.
Results: Analysis of data using test paired sample t-test. Statistical test results obtained a p-value of 0.000 < 0.05 so that Ha is accepted, which means there is an effect of physical activity on foot on blood sugar levels in diabetes mellitus patients in the work area of the Cianjur Kota Health Center in 2021.
Conclusion: This study found that walking exercise as far as 2,5 km for 30 minutes can lower blood sugar levels significantly in patients with diabetes mellitus.


Guidewire fracture (either partial or complete) is an exceedingly rare complication of which is mostly encountered in percutaneous coronary intervention (PCI) of complex lesions. It can be managed mostly with using percutaneous techniques, but at times requires a surgical approach as well. Here, we report a case of a 67-year-old male who underwent PCI of totally occluded proximal left anterior descending artery. Due to excessive manipulation, tip of Sion blue wire (polymer-jacket guidewire) got trapped into the lesion. To unloop the wire, spring tip got partially fractured. The guiding catheter was pushed over the fractured wire near the fracture point and a 2.5 mm × 10 mm Sapphire semi-compliant balloon (Orbus Neisch, Netherland) was inflated near the tip of guiding catheter at 12 atm pressure, and whole assembly was pulled out to successfully retrieve the partially fractured and retained wire.


Although demand for the Web editions of American Chemical Society journals is growing, demand for print editions has declined sharply. This trend is prompting the society to change the format and dissemination of its printed issues. In July, ACS will begin publishing the print editions of most of its journals in a "rotated and condensed" format that will fit two pages of content on one printed page. The new format will reduce paper, printing, and distribution costs for ACS, Journals Publishing Group Senior Vice President Susan L. King notes. It will also have a positive impact on libraries because a single year of the print editions of all ACS journals currently requires 30 linear feet of shelf space. ACS won't increase prices for its print journals next year, but it will stop offering deep discounts on print subscriptions to libraries that have online subscriptions. Customers will also be offered incentives to switch to electronic-only ...

Abstract. We propose a high-birefringence twin-core hollow optical fiber, which is composed of two rectangular Ge-doped cores, annular silica cladding, and a large central air hole. The rectangular cores are weakly coupled with the air hole and arranged in the same silica cladding. The mode birefringence in single-mode operation of 1.55  μm reaches 2.48  ×  10  −  4, which is comparable with traditional panda polarization maintaining fiber. By introducing an extra stress zone, the mode birefringence can be improved further by two times. The high birefringence of the twin-core hollow fiber is induced by strong asymmetry of the waveguide structure. The characteristics of the guiding mode, birefringence, and evanescent field are analyzed numerically by full-vector finite-element method. The effect of geometric and material parameters is discussed. The proposed scheme of twin-core hollow fiber can overcome the polarization fading effect and signal cross talk occurring in traditional multicore fibers and is much desirable for improving the performance of in-fiber integrated interferometers and biochemical sensors.


Although much work lies ahead, San Diego, Calif., is on the path toward developing a new, local, and reliable source of water through potable reuse.


We have developed a method to deal with the crosstalk effects in timing analysis. The method calculates quantitative delay degradation caused by crosstalk even when there are multiple aggressors for one victim and the signal arrival times dynamically change depending on the input patterns. The method can decrease design delay margins and is especially useful for designing high-performance LSIs.


The flow mechanism responsible for the recently discovered buffet-producing critical cylinder length for hammerheads is discussed. For short cylinder lengths, the upstream effects of the hammerhead wake are able to affect the terminal shock location, driving flow separation to the nose-cylinder shoulder. This has the potential to cause aeroelastic instability leading to structural failure. A similar critical-cylinder-length effect exists for cone-cylinderflare configurations. This too involves an upstream flow effect. In this case the flare-induced pressure rise drives the shock-induced flow separation to the cone-cylinder shoulder. Neither of these effects is recognized in the existing NASA guidelines for elastic vehicle design. Some currently proposed designs for heavy lift launch vehicles incorporate dangerously blunt noses, in violation of the NASA aeroelastic design criterion. A reexamination of these nose effects indicates the possibility of aeroelastic instability and structural failure. It is the conclusion of this study that it is imperative to consider aeroelastic stability effects early in the design process in order to avoid the possibility of a flight failure or a costly redesign later in the development cycle if the presence of an aeroelastic stability problem is discovered.


The structures of buildings that use the Light Steel Framing (LSF) constructive method stand out as a possible constructive system for the future, since it effectively addresses and resolves the ecological faults existent in other methods. One of the objectives of this dissertation was to examine, study and evaluate several parameters related to thermal performance, acoustics, fire resistance and sustainability, because these are decisive factors when selecting a construction method. Comparing the construction method in study with the traditional masonry and reinforced concrete solution, it was found that the LSF method presents (i) excellent thermal performance, (ii) good acoustical performance, (iii) excellent durability, sustainability and eco-efficiency indicators. The main objective of this thesis consisted in the development and analysis of a structural model of a LSF building, studying the behaviour of the structure in conjunction with the OSB siding panels and the calculation techniques related with the system, prescribed in EN1993. Modelling the structure in SAP2000 allowed the assessment of the best techniques for computational modelling of certain structural elements and behaviours, predominantly the diagonal straps and the diaphragm effect of OSB. It was then concluded, that this effect should be considered in the structural model due to its influence on the seismic behaviour. Subsequently, the critical design values were analysed in the main structural elements, in order to proceed with its design. Given the complexity of the design process of Class 4 steel sections, this was presented concisely through flowcharts that summarize the requirements of EN1993. Because of the extension of the obtained results, charts which summarize the design values were developed, depending on the type of structural element and section in analysis, so that they can be used in the future for a more efficient pre-design.


The purpose of this article is to present an analysis of the
guidelines provided by professional literature for teachers
working with Roma pupils, and to examine the issue of educating
Roma children based on the experiences of Slovene
primary school teachers. The results of the analysis are far
from encouraging as the recommendations are based on
the assumption that the teacher him/herself will be able to
adjust the teaching methods to produce better results. Feedback
from teachers indicates that they fail to adopt the most
constructive teaching methods when attempting to modify
and adapt classes for Roma pupils. In terms of factors affecting
learning outcomes, the teachers mostly noted only those
relating to the characteristics of Roma students and their
families, while hardly recognising the importance of their
own pedagogical efforts. Furthermore, results show a frequent
lack of understanding of the language barrier faced by
Roma pupils. Therefore, special focus will have to be placed
on improved (additional) training of (future) teachers as
well as on further development of support mechanisms by
various state institutions in this field.


Methanol is an example of a valuable chemical that can be produced from water and carbon dioxide through a chemical process that is fully powered by concentrated solar thermal energy and involves three steps: direct air capture (DAC), thermochemical splitting and methanol synthesis. In the present work, we consider the whole value chain from the harvesting of raw materials to the final product. We also identify synergies between the aforementioned steps and collect them in five possible scenarios aimed to reduce the specific energy consumption. To assess the scenarios, we combined data from low and high temperature DAC with an Aspen Plus® model of a plant that includes water and carbon dioxide splitting units via thermochemical cycles (TCC), CO/CO2 separation, storage and methanol synthesis. We paid special attention to the energy required for the generation of low oxygen partial pressures in the reduction step of the TCC, as well as the overall water consumption. Results show that suggested synergies, in particular, co-generation, are effective and can lead to solar-to-fuel efficiencies up to 10.2% (compared to the 8.8% baseline). In addition, we appoint vacuum as the most adequate strategy for obtaining low oxygen partial pressures.


Experiments are carried out to study the movement of fine grains in soil and its effect on the landslide and debris flow.The grain series at different sections before and after experiments are compared.It is shown that the fine grains move downwards in the direction vertical to the slope surface and mostly are assembled in the middle.The fine grains are more at the tail than at the foreside at the same parallel to the slope surface. It may be thought that the fine grains are assembled at the lower part and foreside of the slope due to the raining and penetration of water,which causes decrease of the permeability at these places.Therefore,the pore pressure increases and pore water are blocked at these places,loading to formation of the sliding face and the landslide or debris flow occurs.

Evaluation of internal energy in a crystal lattice requires precise calculation of lattice sums. Such evaluation is a problem in the case of small (nano) particles because the traditional methods are usually effective only for infinite lattices and are adapted to certain specific potentials. In this work, a new method has been developed for calculation of lattice energy. The method is a generalisation of conventional geometric probability techniques for arbitrary fixed lattices in a finite crystal domain. In our model, the lattice energy for wide range of two- body central interaction potentials (including long-range Coulomb potential) has been constructed using absolutely convergent sums. No artificial cut-off potential or periodical extension of the domain (which usually involved for such calculations) have been made for calculation of the lattice energy under this approach. To exemplify the applications of these techniques, the energy of Coulomb potential has been plotted as the function of the domain size.


Abstract We present 75As nuclear magnetic resonance data from measurements of a series of Ba(Fe1−xCox)2As2 crystals with 0.00 ≤ x ≤ 0.075 that reveals the coexistence of frozen antiferromagnetic domains and superconductivity for 0.060 ≤ x ≤ 0.071. Although bulk probes reveal no long range antiferromagnetic order beyond x=0.06, we find that the local spin dynamics reveal no qualitative change across this transition. The characteristic domain sizes vary by more than an order of magnitude, reaching a maximum variation at x=0.06. This inhomogeneous glassy dynamics may be an intrinsic response to the competition between superconductivity and antiferromagnetism in this system.

Haitians are so far down on their luck that if a world prize existed for the most hapless people they would be edged out on a technicality perhaps only by the Chadians or Bangladeshis. During June in Haiti a tree called le flamboyant blossoms crimson-orange, covering the mountain slopes down to the seashores, scattered among the African-style thatched huts of the barefooted, miserable people. For most of the population Haiti is a prison farm guarded against sea escape by the U.S. Navy and guarded from within by constant military-police surveillance.

Systems and methods for Carrier Sense Adaptive Transmission (CSAT) and related operations in unlicensed spectrum are disclosed to reduce interference between co-existing Radio Access Technologies (RATs). The parameters for a given CSAT communication scheme may be adapted dynamically based on received signals from a transceiver for a native RAT to be protected and an identification of how that RAT is utilizing a shared resource such as an unlicensed band. Other operations such as Discontinuous Reception (DRX) may be aligned with a CSAT Time Division Multiplexed (TDM) communication pattern by way of a DRX broadcast / multicast message. Different TDM communication patterns may be staggered in time across different frequencies. Channel selection for a co-existing RAT may also be configured to afford further protection to native RATs by preferring operation on secondary channels as opposed to primary channels.


Bunkaisan, cultural heritage, is the term used to denote the cultural artifacts commonly recognized in a certain country or region as being worth passing on to future generations due to their high historical, artistic or academic value. The term was originally a literal rendering of the original English, but it is now completely normalized, and is part of everyday speech. At Kanazawa University I even teach a course entitled "Cultural Heritage Studies". But what is the impression held toward the term isan, "heritage"? Looking at the Kojien Japanese dictionary, the definition given is: estate left after death; the property held by a person at the time of their death. The characters, 遺産 , show the meaning: it refers to the property or estate ( 産 ) remaining ( 遺 ) after death. Therein we can perceive the nuance of that which is "left behind". There is a senryu, a type of humorous haiku, from the Edo period (1603-1868) that goes as follows:


Mechanical circulatory support devices (MCS), namely percutaneous ventricular assist devices (pVAD) are temporarily introduced to support circulation in hemodynamically compromised patients and also during mid to high risk coronary artery procedures. Their multiple responsibilities include maintaining an adequate systemic blood pressure and cardiac output to provide satisfactory end-organ perfusion in unloading of the failing ventricle, and to temporary lower myocardial contractility while reducing myocardial oxygen demand supporting favorable ventricular remodeling. To timely and quantitatively assess hemodynamics during pVAD circulatory support post-cardiogenic shock or acute myocardial infarction (MI), pressure-volume (PV) measurements are becoming progressively more appreciated as they can longitudinally evaluate the status of the support. Hemodynamically, importance of constant circulatory interrogations by PV during pVAD support lies in its capacity to "fine-tune" the device for a specific patient to work in synergy with the ailing organ. In this review basic characteristics of a diagnostic value of pressure-volume during pVAD hemodynamic support will be discussed fostering conversation about the necessity of e.g. combining pump flow with load-independent indices creating indexes that can be used to further characterize pump unloading in relation to innate cardiac contractility during axial or centrifugal flow support. Additionally, discussion about central hemodynamics during different flow support will be provided evaluating pVADs to assess its ability to work in synergy and to anticipate potential difficulties that might occur during the procedure. Brief description of recent efforts to combine PV exam with pump flow during circulatory support using pVAD and the concept of pressure-volume area (PVA) and myocardial oxygen consumption (mVO2) during unloading will be also discussed.


The aim of this article is to delineate the growing importance of the international orientation of university education and its impact on teaching learning foreign languages for specific purposes. Initially, the research was devoted to universities and Grandes ecoles in France, a model of the French business school where many international students which provide the host university a strong multicultural identity and international reputation thanks to agreements on cooperation with the most prestigious institutions of higher education in the world. In order to attract students from all over the world, many French universities have developed degree programs in English. Prestigious business schools offer a wide range of courses covering all major fields and strive to ensure a high level of research projects. These institutions offer students an opportunity to spend part of their studies at foreign universities. At the same time, foreign language teaching has been strengthened and modernized. One of the most important innovations is the integration of foreign language learning and teaching with the contents of other subjects. The development of didactics of French for Academic Purposes (Francais sur Objectifs Universitaires – FOU) contributes significantly to the popularity of those universities, because non-French speaking students stand much better chances of success. French for Academic Purposes, as a branch of French for Specific Purposes (Francais sur Objectifs Specifiques – FOS), and as one of the ways to facilitate the integration of foreign students, is increasingly gaining importance in the domain of French as a foreign language.
Serbian schools of management are open to international cooperation and the establishment of agreements on diploma recognition and equivalence in order to facilitate student exchange and Erasmus+ type mobility, but they rarely consider possible improvements in teaching foreign languages for specific purposes by increasing the number of courses and offering several languages in the curriculum, which would make them more competitive. The number of LSP classes per week is insufficient since it equates to an average of thirty hours per semester which are allocated to language learning. Very often, the only language offered to students is English. Although there is a significant disproportion between the desire to expand and strengthen international partnerships and a desire to improve conditions for foreign language teaching, the example of some Serbian universities shows that improvements are possible.


Low-rate low-power consumption and low-cost communication are the key points that lead to the specification of the IEEE 802.15.4 standard. This paper overviews the technical features of the physical layer and the medium access control sub-layer mechanisms of the IEEE 802.15.4 protocol that are most relevant for wireless sensor network applications. We also discuss the ability of IEEE 802.15.4 to fulfill the requirements of wireless sensor network applications.


In this study a single central patch with two or four peripheral parasitic patches was studied. They were identified as the 3CP and SCP antennas. It was found that the 3CP antenna has a wide impedance bandwidth, within which its radiation pattern remained practically constant. Its cross polar radiation was very low. Also, its size could be made small by compacting the configuration. This investigation shows that splitting a patch into three dipoles like narrow patches results in an antenna with a far more attractive performances. It also showed that adding two more dipoles to form the SCP antenna did not improve its performance and resulted in an inferior antenna.


Two organic-inorganic hybrid compounds constructed from polyoxoniobates and transition metal coordination complexes,[Cu(TETA) ] 4 [VNb 12(VO) 4 O 40 ][OH]·10H 2 O(1) and [Cu(TETA) ] 4 · [VNb 12(VO) 6 O 40 ][OH] 5 ·5H 2 O(2)(TETA = triethylenetetramine),have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction analyses,IR spectra,X-ray photoelectron spectrum(XPS),powder X-ray diffraction(PXRD),thermogravimetric analysis(TGA) and elemental analyses.Compound 1 is a 3D tetra-capped vanadoniobates and compound 2 is a 3D hexa-capped vanadoniobates which are constructed from heteropolyoxometalates and [Cu(TETA) ]2 +fragments.The result of bond valence sum calculations indicates that the vanadium centers of VO 4 tetrahedral in{ VNb 12 } Keggin unit in compounds 1 and 2 are in oxidation state + Ⅴ whereas the remaining vanadium centers are in oxidation state + Ⅳ.This is in line with the analysis of X-ray photoelectron spectrum.


Both experimental and clinical studies on cerebral, cardio-pulmonal, hepatic and renal circulation were performed after the head injury. The increase in cerebral vascular resistance and the decrease in cerebral blood flow and oxygen cosumption were found at the early stage following the head injury. In mild case, improvement of cerebral blood flow was preceded by cerebral oxygen consumption, whereas the order was entirely opposite and the duration of recovering time was prolonged in severe cases, The decrease in cardiac output and the increase in pulmonary vascular pressure and resistance, average pulmonary circulating time and pulmonary blood flow were observed after the injury. In addition, the relaionship between portal circulating time and hepatic blood flow was reversely pro. portional, whereas significant reduction of renal blood flow and glomerular filtration rate with elevation of filtration fraction was observed. At the early stage following the injury, arterial oxygen saturation de. creased and the recovery was, in general, faster than improvement of hemo. dynamic change. In conclusien, in severe experimental cases, cardioc output was decreased by 25%/, ; cerebral blood flood flow by 30%/ , hepatic blood flow by 75/o and in clinical cases renal blood flow was decreased by 35%. Recovery of these values were generally required to take about one week in mild cases and about two weeks in severe cases, although there was a severe case showing no improvement of cerebral circulation even after one month following the injury.


Flow pattern quantization formulation is a key to gas liquid two phase flow pattern identification. The flow pattern signals in the transition of stratified wavy flow into slug flow in the gas\|liquid two phase flow pipeline were measured in a general gas liquid two phase flow experimental facility. The singularity of these flow pattern signals was analyzed with singularity theory based on wavelet transform. The singularity between the two phase flow pattern signals is obviously different, and their Lipschitz exponentials can be regarded as a new quantization symbol for flow pattern identification.


PURPOSE
Imaging registration have a significant contribution to guide and support physicians in the process of decision making for diagnosis, prognosis and treatment. However, existing registration methods based on convolutional neural network can not extract global feature effectively, which significantly influences the registration performance. Moreover, the smoothness of displacement vector field (DVF) fails to be ensured due to miss folding penalty.

METHODS
In order to capture abundant global information as well as local information, we have proposed a novel 3D deformable image registration network based on Transformer (TransDIR). In the encoding phase, Transformer with the atrous reduction attention block is designed to capture the long-distance dependencies which are crucial for extracting global information. Zero padding position encoder is embedded into Transformer to capture the local information. In the decoding phase, up-sampling module based on attention mechanism is designed to increase the significance of ROIs. Because of adding folding penalty term into loss function, the smoothness of DVF is improved.

RESULTS
Finally, we carried out experiments on OASIS, LPBA40, MGH10 and MM-WHS open datasets to validate the effectiveness of TransDIR. Compared with LapIRN, the DSC score is improved by 1.1% and 0.9% on OASIS and LPBA40, separately. In addition, compared with VoxelMorph, the DSC score is improved by 2.8% on the basis of folding index decreased by hundreds of times on MM-WHS.

CONCLUSIONS
The results show that the TransDIR achieves robust registration and promising generalizability compared with LapIRN and VoxelMorph. This article is protected by copyright. All rights reserved.

Certain cyanobacteria, such as open ocean strains of Synechococcus, are able to swim at speeds up to 25 diameters per second, without flagella or visible changes in shape. The mea ns by which Synechococcus generates thrust for self-propulsion is unknown. The only mechanism that has not been ruled out employs tangential waves of surface deformations. In (1) the average swimming velocity for this mechanism was estimated using the methods inaugurated by Taylor and Lighthill in the 1950's a nd revisited in differential geometric language by Shapere and Wilczek in 1989. The procedure consists of solving quasi-statically the Stokes equations with no slip boundary conditions. (These are given by the instantaneous velocity field defined by the current deformation of a localized shape. The physical condition of no net force and torque yields a rigid body counterflow, whose average on a stroke cycle gives the average swimming velocity.) In this article we propose making a break with the no slip boundary condi- tion paradigm. In fact, we are proposing here an entirely different physical principle self propulsion based on acoustic streaming. Micro-pumps in silicon chips, based on AS, have been constructed by engineers since the 1990's, but to the best of our know ledge acoustic streaming as a means of microorganisms locomotion has not been proposed before. Our hypothesis is supported by two recent remarkable discoveries: (1) In (3), deep-freeze ele ctron microscopy of the motile strain WH8113 revealed a crystalline outer layer (CS) covered with a forest of "spicules" (Sp) extending from the inner membrane through the CS, projecting 150 nm into the surrounding fluid. (2) In (2), atomic force microscopy (AFM) was used to find that the cell wall of yeast cells periodically oscillates on nano-scale amplitudes at frequencies of 0.8 to 1.6 kHz, and that the oscillations are generated metabolically. We propose that the spicules, in contact with the cell's power systems, coul d perform high frequency motions generating acoustic streaming (AS) in the surrounding fluid. We compare two models for self-prop ulsion employing acoustic streaming: the quartz wind effect (QW) and boundary induced streaming generated by surface acoustic waves (SAW). Based on an estimate of the power required, the former would require an enhancement mechanism similar to a laser to be viable. In striking contrast, we find that the effici ency of the SAW mechanism compares favorably with known strategies for bacterial self-propulsion. The required amplitude is b elow the resolution limit of light microscopy and the required frequency is biologically attainable. Moreover SAW produce an "atmosphere" (the Stokes layer) surrounding the cell, within which the flu id motion is essentially chaotic and thus acoustic streaming may turn out to be biologically advantageous, enhancing nutrient uptake and chemical reactions. Some possible experiments are outlined.


This work presents an extension to the MoveIt2 planning library supporting asynchronous execution for multi-robot / multi-arm robotic setups. The proposed method introduces a unified way for the execution of both synchronous and asynchronous trajectories by implementing a simple scheduler and guarantees collision-free operation by continuous collision checking while the robots are moving.


The landslide is located in Dashui village,Jinzhong Town,Kaiyang County, with geographical coordinates of 106° 51'06"E and 27°08'14"N. The landslide is distributed in the manually excavated slope section on the west side of the substation. medium-sized landslide,which is divided into shallow landslide according to the thickness of sliding mass. The main factor is bedding sliding caused by weathering of fault fracture zone. In this paper, the failure reason and mechanism of anchor cable anti slide pile of existing support structure system are analyzed by established a 3D modeling numerical simulation with the artificial intelligence reduction algorithm. It includes the following working conditions, anchor cable prestress loss failure slope failure mechanism, anchor cable normal and failure mechanism under rainstorm condition.Finally,the new steel pipe pile grouting technology is used to solve the landslide. The scheme makes full use of the flexible and fast construction of micro pile, combines the anchoring capacity of geological body and anchor cable engineering, plays a good role in engineering prereinforcement, greatly reduces the project cost and reduces the problem of construction disturbing resident which has proved to be economical and feasible.


Basic theoretical treatments of quantum beats are presented using the effective Hamiltonian method and the density matrix method. To describe the states involved in quantum beats, the molecular-eigen state basis set and the zeroth order basis set are introduced. Based on these basis sets for the two-state model, the condition under which molecular coherence can be created is discussed.

Technological developments in the digital age today, allowing human use technology such as computers and smartphones for use in all aspects of life. The wing chun organization of Indonesia does not have a computerized system to hold a match. This organization still uses manual system, that is by writing and taking notes on physical documents such as paper. Thus, it needs a system that can simplify the implementation of arrangement, scheduling and recording every game.  The scheduling system and the arrangement system for wing chun matches are made using the PHP 5 (Hypertext Preprocessor) programming language, using the CodeIgniter framework, the authors use the PHP programming language because of its open source nature, so that any changes or additions will be greatly facilitated, because of the well-organized CodeIgniter framework.  In this study, data collection is collected by conducting interviews and direct observation in the field, in order to obtain information that will be used to design the system, so that the system can run in accordance with user needs.  The result of this research is a system used for wing chun matches that can be accessed anywhere by people associated with using communication media such as computers, smartphones that have been connected to the internet.  The conclusion of this study is that this system can facilitate match organizers, for matches, game scheduling and detailed game recording. Suggestions for this system is to develop this system with Android or IOS based version due to the development of smartphones that can equalize computer performance with high flexibility.

Cassava is one of the most important cash crops which are grown in tropical and sub-tropical areas of the world. Cassava is economic plant because it is mostly grown on small farms and it does not require any foreign made equipment or instrument. The price of cassava products is unstable depending on the market demand each year. Hence, the focus of this project is on determinants of income from small scale cassava processing activities in Surulere local government area Ogbomoso Oyo, State. Multistage random sampling was used to select respondents for the study. First stage was the purposeful selection of Surulere Local Government. Second stage was the random selection of ten Villages in the Local Government Area. The third and final stage is the random and proportionate selection of respondents, who are into cassava processing. In all 100 respondents processor were selected. The result shows that majority of the processors are in the 51-60 age group. This indicates that most of those who engage in cassava processing activities are in the active phase of their lives. Most of the respondents were illiterate (61.8%) and would not be able to make good use of extension information effectiveness. Also, majority of the respondents were married (98%) and assistance will come from their spouses but at the same time responsibilities will be increased and will reduce the processors effectiveness. The regression results reveal that the coefficient of the multiple determinations (R2) is 73%. In all this study reveals that initial capital, labour cost literacy levels are the major factors determining income from the small scale cassava processor. On the contrary the older a processor are the less productive they become.

This paper addresses the well-known problem of natural image matting. Most of the previous matting algorithms require the user to define the tri-map, which is an inconvenient work and sometimes a b...


Our main aim is to associate a holonomy Lie groupoid to the connective structure of an abelian gerbe. The construction has analogies with a procedure for the holonomy Lie groupoid of a foliation, in using a locally Lie groupoid and a globalisation procedure. We show that path connections and 2-holonomy on line bundles may be formulated using the notion of a connection pair on a double category, due to Brown-Spencer, but now formulated in terms of double groupoids using the thin funda- mental groupoids introduced by Caetano-Mackaay-Picken. To obtain a locally Lie groupoid to which globalisation applies, we use methods of local subgroupoids as developed by Brown- ˙ Icen-Mucuk.


With the ever-increasing cost of getting to space and the need for safe, reliable, and inexpensive ways to space, many researchers are taking a look at technologies that will get us to space. One of these technologies is Electromagnetic Launch Assist (EMLA). This is the concept of providing the rocket with an initial velocity by using electrical power from ground sources to save fuel and cut down cost. In this paper, the shortages of chemical launch and the fundamental work process of reconnection electromagnetic launcher is described briefly, the fundamental performance of simple reconnection electromagnetic launcher and the effect law that the parameter of driving coil and planked projectile pose on their fundamental performance, and all of these will be a basis of the design for reconnection electromagnetic launcher. And then, based on the features of simple reconnection electromagnetic launcher, the simulation and research for simple system of reconnection Eh4LA are put forward. The result shows that, using this system, we could make the load of about 1 OOOOkg accelerate to the velocity of 180ds with 32 times the acceleration of gravity and then save cost of launch vehicle.

The Open Capacitated Arc Routing Problem OCARP is a well-known NP-hard real-world combinatorial optimization problem. It consists of determining optimal routes for vehicles in a given service area at a minimal cost distance. The main real application for OCARP is the Meter Reader Routing Problem (MRRP). In MRRP problem, each worker in the electric (or gas) company must visit and read the electric (or gas) meters to a set of customers by starting his route from the first customer on his visit list and finishing with the last one. The worker leaves where he wants once all the associated customers have been visited. In this paper, a metaheuristic called an Hybridized Ant Colony Algorithm (HACA) is developed and hybridized with a local search algorithm that involves the 2-opt, Swap, Relocate and Cross-exchange moves to solve OCARP problem. Computational results conducted on five different sets of OCARP-instances showed that our proposed algorithm HACA has reached good and competitive results on benchmark instances for the problem.


A review of the two types of circulators using Operational Amplifiers (OA) with detailed comparison is given. Novel active circulator circuits using Current Conveyors (CCII) and Current Feedback Operational Amplifiers (CFOA) and Differential Voltage Current Conveyor (DVCC) are introduced. The proposed CCII circulator circuit uses six CCIIs and three floating resistors. Two different circulator types using the CFOA are given. A circulator circuit which uses three DVCCs and has the advantage of using three grounded resistors is also introduced. Spice simulation results using 0.5 μm CMOS transistors are included to support the theoretical analysis and demonstrate comparisons among the different types of circulators.


With the promotion of artificial intelligence technology, service robots play an increasingly important role in human life. Compared with industrial robots, the audience of service robots is mostly non-professionals, so robots need to have stronger learning ability and can perform related tasks through human demonstration. This paper designs and develops a robot Learning from Demonstration (LFD) system based on the improved Soft Actor-Critic algorithm. Through continuous maximum entropy inverse reinforcement learning, the human demonstration data can be transformed into a robot executable task model by training. Finally, it is verified via simulation and experiments that the robot can effectively reproduce the human demonstration task through LFD system training.


In recent years, the implementation of bandgap engineering techniques for solar energy conversion has been demonstrated with exciting results, using both quantum wells (QWs) and quantum dots. Here, the exploitation of a fully lattice-matched QW / barrier system is introduced as an attractive new possibility for this type of device. Photovoltaic characterization is performed and relevant solar cell parameters are reported. For these devices, sixteen layers of 5 nm InGaAs QWs / 10 nm InAlGaAs barriers were embedded into the i-region of a 1.0 eV InAlGaAs solar cell, and the results compared to a 1.0 eV InAlGaAs control solar cell. One-sun Jsc is enhanced in the QW cell by 5.3% compared to that of the InAlGaAs control device, while the open circuit voltage is reduced by 153 mV compared to the control. External quantum efficiency measurements reveal a 1.6 mA/cm2 gain from the QW absorption region.


Mitragynine pseudoindoxyl, a kratom metabolite, has attracted increasing attention due to its favorable side effect profile compared to conventional opioids. Herein, we describe the first enantioselective and scalable total synthesis of this natural product in addition to its epimeric congener, speciogynine pseudoindoxyl. The characteristic spiro-5-5-6 tricyclic system of these alkaloids is formed via a protecting group-free cascade relay process in which oxidized tryptamine and secologanin analogs are used. Furthermore, we uncovered that mitragynine pseudoindoxyl acts not as a single molecular entity but as a dynamic ensemble of stereoisomers in protic environments, thus, it exhibits structural plasticity in biological systems. Accordingly, these synthetic, structural, and biological studies provide a basis for the planned design of mitragynine pseudoindoxyl analogs, which can guide the development of next-generation analgesics.


Convergence of conditional expectations is considered. The convergence results for conditional expectations are shown to be the same as when the absolutely continuous change of measure can be made directly. A filtering application is examined. If the approximating model uses noise increments with a density which must have compact support, conditions are given which ensure the expected convergence of the conditional expectations. >


This paper examines how accounting either contributes to or undermines worker resistance to unfair pay, thereby enhancing our current understanding of the emancipatory potential of accounting.,We apply Jacques Ranciere's concept of politics and build on recent calls to introduce Ranciere's work to accounting by analysing a case based on workers in an Australian supermarket chain who challenged their employer Coles over wage underpayments.,We find that in this case, accounting is, in part, a means to politics and a part of the police in Ranciere's sense. More specifically, accounting operated within the established order to constrain the workers, but also provided workers with a resource for their political acts that enabled change.,This empirical research adds to Li and McKernan (2016) and Brown and Tregidga (2017) conceptual work on Ranciere. It also contributes more broadly to emancipatory accounting research by identifying radical possibilities for workers' accounting to bring about change.


WHAT is relapsing fever? It is an acute infectious disease characterized by fever of sudden onset which, after several days rapid remission may relapse at intervals of from one to more days for an indefinite number of times but rarely more than three intervals (third rare) depending on the resistance of the individual. It also might be simply defined as a septicemia caused by spirochetes. The spirochete of relapsing fever is now known as the "Treponema recurrentis." It is very slender but quite long. A peculiar feature is its tendency to disappear suddenly from the blood just before the fall of temperature. During the afebrile stage the blood is still infective to animals and


2008. Access of money determines functioning of each company. Availability of capital and its cost play a key role in the development and expansion of small and medium-sized enterprises. Their development opportunities, in turn, determine company competitiveness and strengthen their market position. The purpose of this publication is to identify the main financial barriers for micro and medium-sized enterprises in terms of their development and use of capital. As the surveyed companies in the Podkarpackie district consistently com-plain about the general lack of accessible capital, regardless of its origin, they also identify the lack of incentives and passivity on the side of the business environment institutions, the predominant reliance on company's own capital, aversion to financial risk and anxiety of meeting invoice payment deadlines as the main impediments to their development pro-spects. The highly-cautious attitude in acquisition of external opportunities to raise capital for new ventures may be one of the main reasons for the enterprises' low rate of growth. Although businesses have good access to information about possibilities of external fund-ing, there are no appropriate forms of incentives and institutional support from external lenders. Elimination of the above mentioned barriers and constraints can help to increase the use of various sources of financing in investment activities of enterprises since financial capital is still the key resource which makes it possible to gain a competitive advantage in the market.


We describe the realization of a 4He magnetometer based on optical pumping with an optical frequency modulated laser diode light. Performances (amplitude and frequency spatial isotropy and sensitivity) of our device are presented and compared with those of other scalar magnetometers.


This study aims to examine the effect of service quality, price and product variants on customer loyalty through brand image as an intervening variable for pharmacy customers in Sidrap Regency during the Covid-19 pandemic. The sample is determined using a purposive sampling technique (determination with certain considerations). Respondents in this study amounted to 100 respondents from the results of calculations using the Slovenian formula. The data was collected using a questionnaire that was sent online to the people of Sidrap Regency. The questions posed in the questionnaire use a linkert scale 1-5 then the data obtained is tested using validity tests, reliability tests, normality tests and regression tests where the data is carried out using the application statistical program version 21. Product and service solution application (SPSS) . To test the mediation (intervening), the method of path analysis (path analysis) is used. The results showed that service quality, price and service variants had a positive and significant effect on the brand image of service quality, prices and product variants which had a positive and significant effect on loyalty, brand image could not mediate the effect of service quality and price on customer loyalty, while brand image can mediate the effect of product variants on customer loyalty.


A radiation integrator is described in which the voltage variation across a condenser, produced by leading ionization currents into it, controls a thyratron relay. When the arc of the thyratron strikes, the event is recorded on a counter, and the condenser is discharged, thus resetting the apparatus to receive a fresh charge. Methods of reducing instability of the thyratron due to H.F. disturbances are discussed.


Work in rural areas is considered an inherently risky activity due to both climatic and/or economic aspects. However, additional risk factors are present, such as hazards posed to the health and safety of rural workers resulting from inadequacy of their organization, which has revealed characteristics increasingly different from those of the urban work, especially in milk production [1]. Milk production is a globally relevant activity that encompasses over 150 million rural properties, with approximately 750 out of 895 million workers directly or indirectly involved in this production.


In this paper the preconvective environment on days with dangerous weather phenomena, such as thunderstorm, hail and squall on the south-eastern part of Western Siberia was investigated. Various thermodynamic and kinetic parameters calculated from radiosoundings of atmosphere at 00:00 and 12:00 UTC were verified against subsequent with dangerous weather phenomena observations derived from meteorological station data. Average values and atmosphere thermodynamic characteristics variability intervals were analyzed, when dangerous weather phenomena were registered on the southeastern territory of Western Siberia. Threshold values of the thermodynamic characteristics of atmosphere of Western Siberia for different degrees of probability of thunderstorms and hail are determined. Variability of indices values, that characterize convection depending on the underlying surface and the time of its development, are defined.


In this study, we explore the vibration damping characteristics of singular liquid drops of varying viscosity and surface tension resting on a millimetric cantilever. Cantilevers are displaced 0.6 mm at their free end, 6% their length, and allowed to vibrate freely. Such ringdown vibration causes drops to deform, or slosh, which dissipates kinetic energy via viscous dissipation within the drop and through contact line friction. Damping by drop sloshing is dependent on viscosity, surface tension, drop size, and drop location. A solid weight with the same mass as experimental drops is used to compare against the damping imposed by liquids, thereby accounting for other damping sources. Neither the most viscous nor least viscous drops studied imposed the greatest damping on cantilever motion. Instead, drops of intermediate viscosity strike the most effective balance of sloshing and internal dissipative capacity. Very thin cantilevers with sloshing drops express more than one dominant frequency and vibrate erratically, often shifting phase, presenting a challenge for quantification of damping. Finally, we introduce a new dimensionless group aimed at incorporating all salient variables of our cantilever-drop system.


If we were to look at the political equivalent of the Encyclopaedia Britannica, the Welsh section for most of the last century would in all probability read "For Wales see Labour," with Labour's successes in Wales so long lasting and comprehensive that, "it was possible to confuse Welsh politics with the politics of the Labour Party in Wales."1 Labour Party management issues were, for example, considered to be of far more consequence to modelling the Welsh devolution settlement, than the influence of external actors, both in 1998 and 2006,2 the latter resulting in the creation of the infamously byzantine legislative system of legislative competence orders (LCOs) and Measures as a party compromise.3 With all the critical debates on devolution held within the Welsh Labour Party, it is little wonder that Wyn Jones has described the constitutional architecture of Welsh Devolution as a testament to the dominance of Labour in Welsh public life.4


Manufacturing companies are continually striving to sharpen their competitive advantage in many ways, such as product-service system (PSS) and inventory control. There are only a few published case studies of PSS in manufacturing contexts, and these tend to be implementations in large sized companies giving only limited knowledge related to complexity and performance of PSS due to issues of confidentiality. Inventory control has been researched for many years and has led to substantial improvements in performance across many industries. To date, very little research has been reported related to inventory control in product-service systems in manufacturing contexts. The research carried out for this paper involved collecting primary data from qualitative research conducted through a case study with a company in the United Kingdom and information from secondary sources. Analysis of the case study data has also identified areas for further research. This research will contribute to the existing body of knowledge by the creation of qualitative models which will provide understanding about types of PSS in manufacturing contexts.
