Injecting malicious script through links, URLs (Unified resource locator) or as user inputs and getting it executed (when inputs are not validated) in the client side is called cross site scripting (XSS) attack. It is called XSS because the script that is executed here is not originated from the same client or from a trusted server. Our solution "Yukti" is devised to detect these application specific XSS attacks at network level by deep packet inspection in the live environment. Existing solutions do static security code review or scans the application for known attack patterns. "Yukti' is dynamic as the suspect engine in the solution is unique and has the capability to suspect a new attack pattern. If the suspect is analyzed to be true, the rule that would detect the attack is built into rule base dynamically. This paper discusses the design, components, architecture, dependencies, techniques, implementation and analysis of results obtained. Our results show that out of huge test cases (70000both XSS and Non XSS) the solution is able to detect 28546 numbers of XSS attacks initially (before appending new rules in detection engine). After appending new rules based on recommendations from suspect engine, it is able to detect 32363 XSS. Yukti demonstrates considerable improvement in the performance when analyzed with leading IDS engine SNORT while detecting XSS attacks General Terms Web Security, Vulnerability Assessment & Intrusion Detection.


The competitiveness of a city is in the process of competitive development. This study uses the Spatial Dubin Model (SDM) technique to explore the influencing factors and spatial spillover effects of the economic competitiveness of 565 cities in Asia. The study finds that the factor spillover bandwidth affecting the improvement of urban competitiveness is primarily concentrated in the range of 1,000 km. Furthermore, with a maximum elasticity value of roughly 11.6%, a city's spatial spillover effect is a crucial factor in selecting strategies for enhancing its competitiveness level. Financial services, industrial structure, and human resources all have an influence on the level of urban competitiveness. Therefore, in order to better improve the level of regional urban competitiveness, one is to improve the overall level of factors affecting urban competitiveness and enhance the competitiveness of the city itself; the other is to enhance the flow of factors between regions and make full use of the space of factors Spillover effects enhance the level of regional competitiveness; the third is to enhance the spatial interaction between regions and use the externality of urban competitiveness to achieve an overall improvement in the level of regional competitiveness.


Tenascin-X (TNX) is a large extracellular matrix protein discovered because its TNXB gene overlaps the CYP21A2 gene encoding steroid 21-hydroxylase (P450c21), whose mutations cause congenital adrenal hyperplasia (CAH). In the 1980s, several laboratories worked to clone the "CAH gene". We sought a P450c21 clone in a cDNA library prepared from a CAH adrenal and identified a transcript larger than P450c21 cDNA; sequencing indicated it was encoded by an unknown ("X") gene overlapping CYP21A2 on the opposite DNA strand. Extensive genomic sequencing revealed the structure of a tenascin: N-terminal EGF-like repeats, multiple fibronectin-III repeats, and a C-terminal fibrinogen-like domain; we named this "Tenascin-X" (TNX). To study TNX function, we postulated a "contiguous gene syndrome"—a single mutation affecting both CYP21A2 and TNXB, causing CAH plus another disorder that might suggest the role of TNX. A patient with CAH and Ehlers-Danlos syndrome (EDS) had partial deletions encompassing both genes. With collaborators, we described patients with recessive TNX-deficient EDS (now termed "classic-like EDS"), which was clinically distinct from dominant EDS caused by collagen mutations. TNX haploinsufficiency causes the mild "hypermobility form" of EDS, often associated with CAH, comprising the unique CAH-X syndrome. The discovery of TNX illustrates scientific serendipity and the value of pursuing unexpected results.


"I think the turning point came…and it wasn't a particularly fun day, the attitude on the unit wasn't very positive. And she went back up and said "I don't, I don't want to work in that kind of an atmosphere". That, that was my foot in the door to say, "Ok, guys, like, we're shooting ourselves in the foot"…but I couldn't recruit staff into that"


Loop Quantum Cosmology provides a successful quantization of isotropic and homogeneous flat universes with a massless, homogeneous scalar field as the matter content. Here, we propose a new ordering for the Hamiltonian constraint operator that facilitates the quantization of this model and makes the physical consequences much more transparent. In particular, our constraint is such that, in the gravitational sector, the zero volume state decouples, allowing us to get rid of the cosmological singularity already at a kinematical level, as well as to introduce a consistent densitization procedure for the constraint. Furthermore, the typical discretization of the spatial volume is achieved in superselection sectors which prove to be most suitable, with support on semilattices and where the basic functions that codify all the relevant information about the geometry have the expected Wheeler-DeWitt limit of standing waves. Thanks to these properties, we can demonstrate that the quantum bounce is generic for any physical state and superselection sector.


In this paper, we develop multi-country indices of financial system stress and quality of financial policies and use them in regression analysis of the determinants of financial stress. We find that countries with higher quality of financial policies are better able to contain the effects of macroeconomic pressures on the overall level of stress in the financial system. They are also in a better position to ensure sustainable development of the financial system.

To serve the studenst well, meet the needs of the reader and raise the rate of using the periodicals,the working personnel must heighten the qualities of their thought and vocational work, carry out strictly the borrowing rules and regulations and serve the students in different ways according to their different levels.


Humpback whales (Megaptera novaeangliae) are a cosmopolitan species that often visit inshore waters close to the coast, making it easier to see and study them. Consequently, this baleen whale has been researched the most, particularly in Colombia. In Aug 2020, ongoing cetacean monitoring was performed by a group of trained fishermen from the Gulf of Tribuga as part of a community science program implemented by the R&E Ocean Community Conservation Foundation as a contingency plan for monitoring marine mammals in the area during COVID-19 lockdown. As a result of these observations of play behavior, the scope of knowledge regarding the social dynamics, developmental processes, flexibility, and cognitive abilities of cetaceans has been expanded.


Among the current translational inflammatory pain models, the ultraviolet (UV) irradiation is of rapidly growing interest. The development of primary thermal and mechanical hyperalgesia has been observed in humans and rodents. The pig as a translational animal model might be advantageous due to its great homology with humans.


—Even though trust plays a significant role during decision-making in open collaborative environments, still Grid user trust mechanisms have not been widely deployed in Grid computing settings. In this paper, a conceptual framework that is an extension of a novel Grid user trust service (GUTS) is presented, which aims at leveraging Grid functionality with trust mechanisms with a special focus on achieving end-user trust in an intuitive and practical manner. Trust in GUTS is utilized during the grid site selection process, where sites are ranked based on expected service requirements for a user grid project. In the proposed conceptual framework, the center of the trust management process is the user who decides and specifies the needs of his/her project, which in turn are mapped to trust requirements.


In this paper, we proposed a space-time code selection technique for multiple transmit antenna OFDM systems and a constant-rate transmission mode for the space-time code selection technique is introduced. One important problem arises in case of MIMO system is, how to code across space and time to obtain the maximum output (minimum BER). For AWGN fading channels, space-time block coding (STBC) is a recent breakthrough solution to this problem. Analysis will be done for an OFDM wireless communication system by using space time block code (STBC) at the transmitter end, and considering the effect and the wireless channel like AWGN fading. A comparison will be made for the above mentioned technique by using different modulation method i.e. BPSK and QAM. The expression for Bit Error Rate will be developed for different input SNR. Performance results will be evaluated numerically and graphically using the plots of BER vs. SNR and Constellation diagram.


Since the existing target orientation estimation methods for laser radars are not robust to the occlusion,a novel 3D orientation estimation method was proposed.The principles of the existing methods and the intrinsic characters of the surface structures for ground targets were analyzed carefully,then the feature of Projection Density Entropy(PDE) was introduced,and the relationship between PDE and target orientation was analyzed.Finally,a 3D orientation estimation method was formulated by iteratively rotating and projecting the target point cloud onto the coordinate planes together with PDE calculation.Comparative experiments were performed on the dataset containing point clouds of 25 ground targets,the performance in self-occlusion,occlusion and the noise were investigated,and the parameter tuning was discussed.The results show that the estimation error of this method is below 3° in self-occlusion,and also no more than 10 ° even in 80% occlusion.It is clear that the proposed method is robust to occlusion and converges quickly,thus is capable of estimating the 3D orientation of ladar targets in complex scenes.

In this work, a simple approach is applied to a quantitative study of the influence of the oxide charge trapping over the drain extension due to electrical stress on the off-state drain leakage current. It is found that positive charge trapping over the drain extension leads to a significant increase in the off-state drain leakage current if the edges direct tunneling (EDT) is dominant in the drain current. For nitrided gate oxide, with the increase of the nitrogen concentration the increase of the off-state drain leakage current becomes more significant due to the nitrogen-enhanced oxide charge trapping.


Some experimental data are analyzed to probe the sub‐shell structure at N≈40. It shows no clear evidence for magic number but is in agreement with a neutron sub‐shell closure more probably located at N=38. The B(E2: 01+ → 21+) transition probability curves of even‐even nuclei from 56Ni to 82Ge are confronted with results of calculations performed in an approximation of the generalized seniority and shown to fit with the N=38 sub‐shell closure and a scenario involving p‐n interaction accordingly to the Federmann and Pittel mechanism.


This paper first introduce some codes may be applied to network-on-chip.Then choosing several highly effective and easily realizable codes to design error control circuit.However,taking into account the integration of the chip continuous improvement,propagation delay caused by crosstalk and power consumption caused by capacitive coupling,this paper also adopts a code to avoid crosstalk,combined with the parity codes to achieve error control.Through the simulation,the function of error control circuits is completely correct.

Increasing the access to information and augmenting the process of information exchange, Information Communication Technology (ICT) offers the potential to increase efficiency, productivity, competitiveness and growth in various business and social sectors. The study thus investigated the use of ICTs among cattle farmers in Oke-ogun Area of Oyo State. Snow ball technique was used to sample 75 cattle farmers from four randomly selected Local Government Areas in Oke-ogun area and structured questionnaire was used to elicit information on respondents' personal characteristics, awareness of ICT, use of ICT components and messages in cattle management. Findings revealed that the most frequently used ICT components are telephone, radio, meetings/ workshop, television and camera with total frequency scores of 106, 100, 99, 48 and 47 respectively. On the other hand, ICT tools such as DVD (9), drama (12), internet (14) and computers (17) were the least frequently used in livestock management. Age and level of education had significant relationships with use of ICT (r = 0.353 and 0.612, p Key words: Technology use, Information Communication Technology, Traditional communication tools, Cattle farmers.


Aristotle's notion of qualitative interaction ruling both the process of mixture and the process of reciprocal elemental transmutation is based upon the idea of a physical contrariety endowed with two extremes and a wide central area where the opposite forces reach different equilibrium points (i.e., the so-called mixtures) or can be present to the fullest degree (in this case we do not have a mixture, but an element). Differently from previous scholarship which attributes this notion specifically to Aristotle, we have found, in a text which Aristotle seems to have been acquainted with, the Hippocratic De victu, an incipient structure of a contrariety endowed with extremes and a central area where opposite forces meet and yield respective equilibrium points, mixtures, which, as in Aristotle, give an account of the variety of beings existing in the world. In this article, we suggest the possibility that in the development of the Aristotelian thinking about elemental and qualitative dynamics, the Hippocratic De victu may have contributed to suggesting to Aristotle a way of envisioning the structure of his basic physical contrarieties.


Let C be a closed bounded convex subset of a Banach space X with 0 being an interior point of C and pC(.) be the Minkowski functional with respect to C. Let B(X) be the family of nonempty bounded closed subset of X endowed with the Hausdorff distance. A generalized mutually minimization problem minC(F,G) is said to be well posed if it has a unique solution (x. z) and every minimizing sequence converges strongly to (x. z). Under the assumption that C is both strictly convex and Kadec, G is a nonempty closed, relatively boundedly weakly compact subset of X, using the concept of the admissible family M of B(X) , we prove the generic result that the set E of all subsets F such that the generalized mutually minimization problem minC(F,G) is well posed is a dense subset of M. These extend and sharpen some recent results due to De Blasi, Myjak and Papini, Li, Li and Xu, and Ni, etc.

In wireless communications, spatial diversity techniques, such as space-time block code (STBC) and multiple-input multiple-output (MIMO), have attracted much attention in recent years because they possess powerful robustness against signal fading. In this paper, we investigate the performance of the protograph low-density parity-check (LDPC) codes over space-time block code (STBC) Rayleigh fading channels. Taking into consideration the Alamouti STBC structure, we propose a modified protograph extrinsic information transfer (PEXIT) algorithm in order to analyze the convergence performance of protograph codes in such scenarios. We further compare the decoding thresholds and bit error rates (BERs) of two typical protograph codes, i.e., accumulate-repeat-by-3-accumulate (AR3A) code and accumulated-repeat-by-4-jagged-accumulate (AR4JA) code, with the regular LDPC code and optimized irregular LDPC codes. The results illustrate that the AR3A code outperforms other three codes in the high signal-to-noise-ratio (SNR) region. As a consequence, the AR3A code appears to be a better candidate for use in the wireless communication systems with multiple antennas.

Background: We compared the evolution of US index in vivo (morphological tumor size, tissue elasticity and microvascular flow) with whole-slice fluorescent immunohistochemical marker maps at different stages of murine tumor development. Methods: Murine colorectal carcinoma (CT26) was subcutaneously implanted in 49 mice on Day 0 (D0). Mice were randomized for data acquisition on D7, D10, D14, D16 and D17 (n = 10 each day except for D16 n = 9). Tumors were measured in B-mode along major transverse and longitudinal axes to estimate ellipsoidal volume. Contrast-Enhanced Ultrasound (CEUS) performed with Sequoia 512, 7-14 MHz probe and with syringe-pump-controlled bolus injection in the caudal vein of 40 μL of SonoVue (Bracco Suisse) and Shear-Wave Elastography (SWE; SSI, Aixplorer, SL 15-4 probe) maps were acquired along the longitudinal axis. Whole-slice histological sections were prepared with fluorescent immunohistochemical staining and parametric maps were made with in-house software to estimate the % area of nuclei, apoptosis (AP) and vascular endothelium (VE) marker. Regions with no contrast-enhancement were identified to estimate % perfused area (%P) and to construct perfused (P) and nonperfused (NP) masks that were then co-registered to SWE maps. Mean and standard deviation (SD) of the SWE could be calculated in whole tumor, P and NP zones. Average contrast intensity vs time curves in the P zone were fit to a lognormal model to estimate Area Under the Curve (AUC), Peak Enhancement (PE), Time to Peak (TTP), Mean Transit Time (MTT), Wash In Rate (WIR) and Wash Out Rate (WOR). The non-parametric Wilcoxon rank and Spearman tests were used to test respectively parameter evolution and correlation. Results: SWE and CEUS parameters did not correlate. SWE did not differ significantly for P and NP zones. Only TTP (RS = 0.47, p = 75%) and did not correlate with tumor volume. Individual histological parameters did not change significantly with time or tumor volume, but % area of strong co-marking of VE and AP decreased significantly between D10 and D14/16. Conclusions: These preliminary results probe the relationship between tumor volume, functional-flow and elastic properties in tumors. One CEUS parameter correlated with tumor growth and thus appears to be sensitive to changes occurring during tumor development. Lack of correlation between SWE and CEUS parameters suggests that they provide complementary information. Nevertheless, it is better to understand the sensitivity of these non-invasive parameters to changes occurring during tumor development in order to obtain a predictive tumor growth parameter. The difference combination of these parameters will change the clinical practice, allowing an early therapeutic adaptation without loss of opportunity to take the good treatment for the patient and without unnecessary therapeutic costs.

A detailed medical history is commonly regarded as a reliable means of classifying unexplained childhood losses of consciousness into diagnostic groups such as febrile seizures, epileptic attacks and breath‐holding spells. The authors have tested this assumption by comparing adolescent follow‐up status with the initial medical history in 56 individuals who suffered sudden losses of consciousness before age five. Only three of these 56 were epileptic when followed‐up in adolescence and only two had received anticonvulsants at any time. The prognosis for 26 individuals with afebrile seizures without evidence of breath‐holding syncope was not significantly worse than that for another 16 with febrile seizures. These findings indicate a good prognosis for untreated childhood seizures of a type often classified as epileptic.


The history of crime has very largely been a history of men, as perpetrators, lawmakers, law enforcers and analysts. Often, in a different way, victims too. Though men or 'males' have been on the criminological agenda for a long time, this has usually been through an implicit, biologicallybased sex role approach. Indeed politicians, policy makers and criminologists have generally been woefully slow in naming crime as largely men's business, and the 'man question' as a central concern. In 1994 Newburn and Stanko's edited collection 'Just Boys Doing Business': Men, Masculinities and Crime was published. This was a landmark, in the UK at least, in making men and masculinities an explicit object of attention in criminology. It built on considerable earlier work, most obviously: feminist criminology; general, broadly pro-feminist, critical studies on men; and a smaller amount of critical studies specifically focusing on men and crime. In the book the editors went as far as to say that, "The most significant fact about crime is that it is almost always committed by men." In CJM in 1995, Betsy Stanko highlighted such issues as men's domination of offending, prisoners as men, male bonding and 'machismo' in police culture, and gendering of male-on-male victimisation. I shall not repeat discussion of those issues, but briefly review some recent general issues brought to the foreground in Critical Studies on Men (CSM), and consider their implications for crime and criminology.


It is well, then, at times to remind ourselves that, in the nature of the case, to begin with at least, Christianity was not a religion of a book ; or if, in any sense, primitive Christianity was a religion of a book, that book was not the New Testament, but the Old. The very idea of a collection of books of the New Covenant, to take their place alongside the books of the Old Covenant, and even to take precedence of them, was comparatively late in its


The object of the studies discussed is to determine the amount of energy absorbed by the steel shells of a 2600pound cask falling horizontally from a height of 23 ft. In addition, information is presented which will help predict the failure of similar casks dropped from different heights. The results of 22 drop tests are summarized. Included in the 22 tests were five tests of larger casks, weighing about 11,350 lbs. The larger cask test results compared favorably with the smaller cask test results. (auth)


An investigation was carried out on the efficacy of using multiple media in the isolation of Mycobacterium tuberculosis from specimens other than sputum, during the period 1980-1984. Of a total of 3807 specimens examined, 818 were urine, 1428 cerebrospinal fluid (CSF), 567 lymph glands, 94 pus samples, 224 operation specimens, 91 gastric aspirates, 108 ascitic fluid and 477 were other types of specimens. Each specimen was inoculated onto one set of media consisting of two slopes each of 'Lowenstein-Jensen' medium (LJ), LJ medium containing 0.5 per cent sodium pyruvate (LJP) and 7H11 oleic acid albumin medim (7H11) and two bottles of selective Kirchner's liquid medium (KL). In all, 550 (14%) were positive by culture in any one of the four media used. Considering the different media individually, KL had the highest efficiency yielding 339 (62%) of the total 550 positive cultures. Also, KL detected 162 positives which were not positive by any of the other media. This was followed by LJ with 328 (60%) positives. LJ and KL when considered together detected 93 per cent of the positives and LJ, LJP and KL increased the positivity to 99 per cent. Thus LJ and KL seems to be the best combination for the isolation of mycobacteria from specimens other than sputum.


One of the current approaches to improving business organizations is agile project management. It emerged in the software industry in 2001, but gradually entered other, non-software industries. However, the transfer of the approach to the public sector requires a specific transformation of the agile methodology, insofar as the two sectors are radically different. The public sector is predetermined by regulations, insufficiently oriented towards service users, bureaucratized and hierarchically organized. All this is a barrier to agile project management that aims at providing project team autonomy, frequent and honest feedback to clients and other stakeholders, flexibility of project scope, etc. The aim of the article is to present a conception of a methodology for agile project management in the public sector and to discuss the issues related to its implementation in governmental organizations.

ABSTRACT Child inactivity, overweightness, and obesity are recognized problems in the United States. Despite characterization as an "epidemic," children continue to fall short in meeting physical activity recommendations necessary to maintain proper health. Relevant literature indicates that after-school programs (ASPs) are viable options for promoting physical activity (PA) in youth. Little research has investigated the PA of children identified as overweight or obese within ASPs. The purpose of this study was to describe PA engagement during an ASP focused on promoting healthy lifestyles in overweight and obese children with regard to PA, nutrition, and emotional well-being. Results indicated differences in step counts, minutes of activity, and minutes engaged in moderate to vigorous physical activity between participant groups and between different lessons within the ASP curriculum. Findings indicate that curriculum, lesson objectives, and the nature of games and activities influence the amount of PA achieved by children in ASPs.


This policy brief examines key considerations policy makers face related to the effects of different tobacco tax structures on prices, tobacco consumption and tobacco tax revenues. It demonstrates that specific excise taxes are the best option for all countries, particularly for lowand middle-income countries where tobacco use tends to be high and taxes tend to be low. Overview of taxes on tobacco products


Drop manholes, a typical element of urban drainage networks in steep catchments and in reaches of supercritical flow, enhance air entrainment and entrapment. The air flow across drop shafts can be remarkably high. This paper discusses the air transport phenomena and the effects of ventilation absence in drop manholes. Based on an extensive experimental study, air entrainment mechanisms have been accurately described and air demand has been evaluated in different flow regimes. In addition, the effects of ventilation absence on the hydraulics of circular drop manholes, with emphasis on sub-atmospheric pressure onset and pool depth raising, have been investigated. The effects of a possible air flow recirculation have also been evaluated. Issues regarding any scale effects have been discussed. The influence of the main hydraulic and geometric parameters on drop manhole performance was contemplated to provide improved design concepts for sewer systems.

In an effort to take positive steps toward coping with problems for families and children created by high levels of separation and divorce, ever increasing civil caseloads and the exposure of children to interparental conflict, court-affiliated educational programs have emerged in the United States for parents separating from their spouse or partner or going through a divorce. This article will provide an overview of the creation of such programs and their development, which includes a discussion regarding the numerous states currently mandating parents to attend. It will summarize some of the research which has been conducted as to the efficacy of the programs and will provide the results of our nationwide research for each state's parent education status. There is a discussion of domestic violence issues and sensitivities in the context of parent education programs and possible future directions for mandatory parent education.


This article examines events of empathy as they occur during artmaking using the lens of agential realism. We do this to trouble more traditional psychological constructs of empathy and, instead, rethink it as performative and relational. Drawing on new materialisms and Karen Barad's 'agential realism', we do not treat artmaking, young people and empathy in any hierarchy but want to understand how these come together as 'things-in-phenomena'. Written recountings of a video artwork are used in mapping the entanglements of cats and dogs with three Finnish high-school girls as they answer the question 'what is empathy?'. The study shows how objects/materials/matter(s) are agentic in co-constituting conditions invocative of empathy phenomena during artmaking. We conclude by suggesting that an agential realist account of art and empathy calls for art educators to pay close attention to objects/materials/matter(s) in their heterogenous connections.

The main object of this paper is to obtain estimations of Hausdorff as well as fractal dimensions of global attractors and pullback attractors for both autonomous and nonautonomous partial functional differential equations(PFDEs) in Banach spaces. New criterions for the finite Hausdorff and fractal dimensions of attractors in Banach spaces are firslty proposed by combing the squeezing properties and the covering of finite subspace of Banach spaces, which generalize the method established in Hilbert spaces. In order to surmount the barriers caused by the lack of orthogonal projectors with finite rank, which is the key tool for proving the squeezing property of partial differential equations in Hilbert spaces, we adopt the state decomposition of PFDEs based on the normal adjoint theory and obtain similar squeezing property. At last, the theoretical results are applied to three specific PFDEs, the retarded nonlinear reaction-diffusion equation, the retarded 2D-Navier-Stokes equation and the retarded semilinear wave equation. Optimal Hausdorff dimension estimation compared with previous works in Hilbert spaces and explicit bound on fractal dimensions that is not depend on the entropy number but only depend on the spectrum of the linearized equations are obtained.


Language policy debate is often obscured by two factors: failure to acknowledge different time-frames attending contrasting positions, and failure to recognise that ordinary people are motivated by their perceived best interests in the present. This article argues that the key to more general public acceptance of linguistic ecological diversity in South Africa is to shift the emphasis from policy development to practical language cultivation issues. Provide the requisite cultivation support, and acceptance of a revitalised future for African languages becomes more assured. It should also be understood that the modernisation of African languages in South Africa has a political dimension concerning which South African language commentators are strangely silent. This political thrust may not be entirely congruent with the concerns of those whose brief for African languages is primarily cultural or ecological-if, indeed, they are even aware of it. Finally, it needs to be recognised that language development under conditions of controlled influence, as in the civil service or schooling, is potentially achievable (with whatever difficulty), but that this must be complemented by authentic contemporary intellectual work published in African languages if the linguistic dimension of the African Renaissance is to take off.


Periocular refers to the externally visible region of the face that surrounds the eye socket. This feature-rich area can provide accurate identification in unconstrained or uncooperative scenarios, where the iris or face modalities may not offer sufficient biometric cues due to factors such as partial occlusion or high subject-to-camera distance. The COVID-19 pandemic has further highlighted its importance, as the ocular region remained the only visible facial area even in controlled settings due to the widespread use of masks. This paper discusses the state of the art in periocular biometrics, presenting an overall framework encompassing its most significant research aspects, which include: (a) ocular definition, acquisition, and detection; (b) identity recognition, including combination with other modalities and use of various spectra; and (c) ocular soft-biometric analysis. Finally, we conclude by addressing current challenges and proposing future directions.


Areas in many rural and costal zones, particularly in developing countries, have a demand for a lower-price, low maintenance, environmentally friendly, and decentralized small-scale desalination systems. For these regions, a new thermal desalination system with heat recovery has been developed and tested in different countries. The system has two components: a desalination tower with multiple stages and a set of solar thermal collectors. Sea and ground water can be fed on the top stage of the tower, and it flows down filling the lower stages. The tower produces desalinated and decontaminated water in its 5–7 horizontal stages. The present work presents the field results of two systems tested in Brazil, and the numerical results of a design installation for Namibia. For Namibia, six systems are planned with capacity of 400–500 L/d. Seven systems use flat plate collectors and tree systems use evacuated tube collectors. In Brazil, two systems with a 35–40 L/d capacity, one with evacuated tube and the other f...


The expression of proto‐oncogenes involved in myelomonocytic differentiation was studied in 3 metastatic murine lympho‐macrophage hybrids (ESb, EbF1, EbF2‐C4) which display several antigenic and functional macrophage properties. Constitutive expressions of fos and fesmRNA, which were not detectable in the weakly metastatic parent lymphoma (Eb), was shown in all the proliferating hybrid lines. By contrast, c‐myc and c‐myb expressions were shared by the tumor parent and the hybrids. The c‐fos transcripts observed in the hybrids were atypical in size, 2.3 kb, but standard 2.2‐kb transcripts could be detected in serum‐induced cells, even in the non‐expressing Eb lymphoma. The kinetics of the induced fos mRNA was found to conform to the features reported in the literature for a large variety of cells. No structural alteration of the c‐fos gene was detected by Southern analysis. PCR amplification of the 2.3‐ and 2.2‐kb fos mRNA showed that they are identical in size in both the coding and the 3′ untranscribed region. A longer poly A tail is thought to account for the additional 100 bp in the 2.3‐kb fos mRNA, as both the 2.3‐ and 2.2‐kb transcripts attain the same size following de‐adenylation. © 1992 Wiley‐Liss, Inc.


Detecting related, ongoing actions of attackers is significant for providing a complete situational assessment of security and determining the most effective reactive defense measures for a network. The logs generated by software running across the network can be used for this purpose, since they may contain the traces of malicious activities occurring inside the network. Primary logs that indicate security alerts such as vulnerability exploits can be used to compute the attack paths that are likely being followed by the attackers. Attack graphs are utilized to represent the attack paths. One of the main contributions of this thesis work is the proposal of a distributed attack graph generation algorithm eliminating the scalability problem inherent in attack graph computation for even medium scale networks. Secondary logs are not directly related to security alerts. However, the usage of these logs can provide more insight into the activities of the attackers. We contribute to the secondary log processing by generating behavioural malware signatures and matching them to the secondary logs. The instantiated malware signatures are integrated with the computed attack graphs. The scalability problems caused by the high volume of secondary logs are alleviated by utilizing a stream-based Big Data infrastructure. Response to the ongoing attack scenarios is performed by applying an optimization method that utilizes a specifically designed candidate selection function and the computed attack graphs.


Commissioned by the Australian Education Union (SA), this report identifies significant shortcomings in the 2003 literacy and numeracy testing conducted in South Australian schools. The authors argue that well-designed standardised tests can be useful as one part of an assessment regime, but the current tests need to be improved considerably.


In the recent, the aspect of foresight is considered globally important. Specially, it has gained a meaningful position in strategic planning. This study examines the quantitative relationships between strategic foresight, ambidexterity and competitiveness of firms. Based on the literature review, it appears that strategic foresight has positive impact on organisational ambidexterity which in turn contributes to competitive advantage. We have utilised structural equations modeling (SEM) to empirically test the mentioned relationships in Iran's nanotechnology firms. Results show that the degree of strategic foresight has a direct effect on organisational ambidexterity which in turn affects competitive advantage.


The ion source for the Spallation Neutron Source* (SNS) is a radio frequency, multi-cusp source designed to produce ~ 40 mA of H - with a normalized rms emittance of less than 0.2 pi mm mrad. Once the SNS is fully operational a beam current duty-factor of 6% (1 ms pulse length, repetition rate of 60 Hz) will be required to inject the accelerator. To date, the source has been utilized in the commissioning of the SNS accelerator and has already demonstrated stable, satisfactory operation at beam currents of ~30 mA with duty-factors of ~0.1% for operational periods of many weeks. Very little data exists describing source performance at higher duty-factors over sustained run-periods. This report presents the results of four tests, each ~1 week in length, in which the ion source was tuned for maximum beam current and operated at elevated duty-factors in the range of 2-7%.


we can only guess what that truth was.' That seems to express quite adequately the scholarly consensus on this parable. If we must use the ' guess ' method in dealing with this parable (as apparently we must) surely it is not unreasonable to push our guessing back to embrace the setting for its telling, its Sitz im Lebenz. A fairly reliable test of such a guess will be in the consistency of the interpretation of the parable suggested by the guess with what we know of the general pattern of the teaching and teaching methods of Jesus. My guess is that Luke arranged his materials to indicate the setting for this parable and that it was told almost immediately after the telling of the Parable of the Prodigal Son, or under


A sequence-specific oxidative degradation of an oligopeptide consisting of aliphatic amino acids was performed with a ternary cobalt(III) complex. Under aerobic conditions the reaction of [Co(CO3)(OH)(terpy)] and an equimolar amount of tripeptide at 40 °C at pH 8.5 gave two fraction bands (a and b) with water and then two bands (c and d) with NaCl solution, respectively, after column separation. In the case of gly-gly-leu (ggl, 1), [Co(gg′l)(terpy)] [1a, gg′l = glycyl(2-oxoglycyl)leucine], [Co(g′l)(terpy)] [1b, g′l = N-(2-oxoglycyl)leucine], [Co(ggl)(terpy)]+ (1c), and [Co(terpy)2]3+ (1d) were obtained. The crystal structure of 1c, which was the main product, revealed that the starting ggl ligand was cleaved to give a bis-amide compound, g′l, which might be generated by loss of N-terminal glycine and carbonylation of the α-carbon of the N-2 glycine residue. Although the source of the oxygen of the newly generated carbonyl group is not clear, gg′l is supposed to be an intermediate for g′l on the basis of time-dependent HPLC analyses. NMR investigation of other tripeptides [βala-gly-leu (2), gly-gly-phe (3), and gly-gly-ala (4)] containing a bulky C-terminal aliphatic side chain indicated the formation of the corresponding oxidation complexes. On the other hand, peptides containing a C-terminal glycine residue [gly-gly-gly (5) and phe-gly-gly (6)] or an N-2 β-alanine residue [gly-βala-leu (7)] did not give such a transformation product. The crystal structure of [Co(fgg)(terpy)] (6c) revealed that the tripeptide is coordinated to cobalt with a tridentate N-terminal N-N-N geometry. Such sequence specificity demonstrated in the reaction of the aliphatic tripeptide complexes is interpreted by the interligand interaction between the side chain of the C-terminal amino acid residue and terpy.

Abstract The object of this study was to develop microparticles from poly (D,L-lactic-co-glycolic acid) (PLGA) using solvent evaporation method for oral vaccine delivery. The PLGA microparticles were coated with chitosan that varying molecular weight (50000, 100000, 200000), concentration (0.25%, 0.5%, 1.0%, 1.5%, 2% w/w), Cetyltrimethylammonium bromide (CTAB) 1.0% w/w and mixture of chitosan and CTAB in the ratio of 1:1. The obtained microparticles had average size in the range of 1.517 to 5.077 micrometers. Microscopic images from scanning electron microscope showed spherical shape with smooth surface. The microparticles had positive surface charge (10.4-66.4 mV) and could adsorb Ovalbumin (OVA) about 32.3-75.0% w/w. The 1% w/w CTAB-coated microparticles showed the highest OVA-loading. In conclusion, the developed microparticles by coating with these cationic agents showed the optimum size which was smaller than 10 micrometers and the positive surface charge, resulting in the higher protein adsorption. These microparticles possibly act as the appropriate protein delivery system targeting to peyerus patches of small intestine for oral vaccine.

Nitric oxide synthase (NOS) catalyzes the formation of nitric oxide (NO) and citrulline from L-arginine, dioxygen (O2), and nicotinamide adenine dinucleotide phosphate (NADPH) in a two-step reaction, with the enzyme-bound intermediate Nω-hydroxy-L-arginine (NHA). Previous electron paramagnetic resonance (EPR) studies of NOS reaction have shown that (6R, 1'R, 2'S)-6-(l',2'-dihydroxypropyl)-5,6,7,8-tetrahydropterin (H4B) acts as a single electron donor in both steps of the reaction, resulting in the transient generation of a tetrahydropterin cation radical (H4B•+).

H4B•+ can also be chemically generated in strongly acidic solutions. EPR studies of chemically generated H4B•+ and similar pterin radicals date back to the 1960s. However, the reported paramagnetic parameters of H4B•+ in NOS do not seem to match the corresponding reported parameters for either H4B•+ or other pterin centered radicals chemically generated in solution. In particular, the rather isotropic hyperfine coupling of ca. 45 MHz for 1H6 of H4B•+ in NOS is at least 15 MHz larger than that of H4B•+ or any other previously studies pterin solution radical. In the work reported here, a combination of 9.5 - 9.8 GHz contentious wave (cw-) EPR, 34GHz 1H electron nuclear double resonance (ENDOR), spectral simulation and Density Functional Theory (DFT) calculations were used to investigate this seeming discrepancy.

We demonstrated that the differences in the paramagnetic parameters of the chemically generated H4B radicals in solutions and those of the H4B radicals in NOS are consistent with the presence of two different conformers of the same cation radical in the two media.

Interest in vegetable oil extracted from idioblast cells of avocado fruit is growing. In this study, five extraction methods to produce avocado oil have been compared: traditional solvent extraction using a Soxhlet or ultrasound, Soxhlet extraction combined with microwave or ultra-turrax treatment and supercritical fluid extraction (SFE). Traditional Soxhlet extraction produced the most reproducible results, 64.76 ± 0.24 g oil/100 g dry weight (DW) and 63.67 ± 0.20 g oil/100 g DW for Hass and Fuerte varieties, respectively. Microwave extraction gave the highest yield of oil (69.94%) from the Hass variety. Oils from microwave extraction had the highest fatty acid content; oils from SFE had wider range of fatty acids. Oils from Fuerte variety had a higher monounsaturated: saturated FA ratio (3.45–3.70). SFE and microwave extraction produced the best quality oil, better than traditional Soxhlet extraction, with the least amount of oxidizing metals present.


To outline the functions of any organization and to fix their exact limits would be difhcult. It is better, perhaps, that lines of demarcation cannot be definitely and accurately drawn. An efficient organization must be capable of such adaptations as will enable it to meet the needs and to profit from the opportunities which each new age thrusts upon it. Stereotyped forms cause endless harm and hamper progress. They become obsolete and must finally be discarded. Our institutions must remain elastic ; otherwise their capacity for good declines. Vjhat have the custom-bound nations of the earth taught us, if not the need of this very quality of elasticity to render effectual the work of human agencies striving

Reversible logic has comprehensive applications in communications, quantum computing, low power VLSI design, computer graphics, cryptography, nanotechnology, and optical computing. It has received significant attention in low power dissipating circuit design in the past few years. While several researchers have inspected the design of reversible logic units, there is not much reported works on reversible subtractors. In this paper we proposed the quantum equivalent circuit for SRK gate and we have computed the quantum cost of SRK gate. We also showed that how SRK gate can work singly as a half-subtractor circuit. It is being tried to design the circuit optimal in terms of number of reversible gates, number of garbage outputs, number of constant inputs, and quantum cost with compared to the existing circuits. At last we proposed an implementation of the new full-subtractor circuit based on SRK gate. All the designs have nanometric scales.


The search for software quality results in the adoption of best practices in the software development process, such as the practices specified by the CMMI maturity model. However, the CMMI implementation constitutes a difficult and slow process. Besides, the quality of such a process directly affects the results obtained. This article explores the possibility of formalizing the CMMI practices via their mapping into Business Rules. This proposal viability was studied through the mapping of the CMMI part that concerns the Requirements Management area. This approach implies in an improvement of the CMMI certification/audit process and of the information system that supports the software development process.

In expository discourse, listeners ask questions in response to unsatisfactory explanations. A system that explains interactively must be able to recognize how to elaborate its answer to produce an explanation that meets a listener's informational needs. Sometimes, listeners ask questions that digress from the purpose of the discussion. Therefore, a system that provides interactive explanations must also be able to distinguish pertinent questions from questions that digress from the discussion purpose. It must also be able to recognize questions that are incoherent. This paper discusses the representation issues that are involved in building such a system. The Interactive Discourse Planner (IDP) plans text to describe and/or justify a domain plan interactively. To perform these tasks, both the system's text plans and the domain plans are represented uniformly. The uniform representation of information makes it possible for IDP to access both domain and discourse information to recognize how to plan each response. The system's planning rules refer to information at both the domainand discourse-level. Therefore, these levels of information are reasoned about together to plan additional discourse. IDP uses questions from the user to recognize how to extend its own text plan in a way that both satisfies its listener and achieves the system's discourse goal. In the process of trying to recognize ways to expand its own text plan, IDP can detect three types of digressions from the discourse purpose that the user can initiate with a question. Two types of text plan representations that are used in the system make it possible for the system to distinguish these types of digressions. As a testbed, IDP plans text to discuss driving route plans.


The electrical energy needs for the traffic lights in some cities of developing countries cannot be achieved continuously due to limited capacity and interruption of electricity distribution, the main power plant. This issues can lead to congestion at the crossroads. To overcome the problem of street chaos due to power failure, we can cultivate to provide electrical energy from other sources such as using the bumper to generate kinetic energy, which can be converted into electrical energy. This study designed a generator mechanic that will be mounted on the bumper construction to generate electricity for the purposes of traffic lights at the crossroads. The Mechanical generator is composed of springs, levers, sprockets, chains, flywheel and customize power generator. Through the rotation of the flywheel, we can earned 9 Volt DC voltage and electrical current of 5.89 Ampere. This achievement can be used to charge the accumulator which can be used to power the traffic lights, and to charge the accumulator capacity of 6 Ah, the generator works in the charging time for 1.01 hours.


Hospitalization is the home route after discharge of elderly patients with heart failure are associated with a high mortality rate (up to 50 % in the first six months) and repeated re–hospitalizations in the first three months, with a peak within thirty days of discharge despite therapy. Telehomecare offers concrete answers to the needs of specialized assistance, usable and in real time, but, on the other hand, the telematic follow–up lends itself to a considerable degree of distrust of non–traditional organizational models.

 The primary objective of this project is to evaluate the reduction of re–hospitalizations through a telematic follow–up by creating a low–cost virtual clinic. Secondary objective to assess the quality of life in the elderly large patient and the managerial continuity between hospital–home. MATERIALS AND

 An initial narrative review of the literature was conducted by consulting the major data–bases available (Pub–Med, Chinhal and Cochrane Library) and then a qualitative survey of a sample of convenience of 31 users with an average age of 80,4 aa to assess the effectiveness of virtual follow–up . To assess the quality of life (qol) will be administered the questionnaire MLIHF Minnesota living with Heart Failure. The data will then be recorded on an excel sheet and analyzed through the R–Studio software.

 Through telemedicine interventions and teleconsultation has been achieved to a greater awareness of the health status of the patient and an empowerment of the selfcare that helps to ensure therapeutic adherence and to contain and/or avoid the progression of NYHA class, also improving the quality of life and the disconfort of travel

 Home telemonitoring opens up new perspectives for chronically serious patients and shows potential benefits for patients' quality of life and cost containment. In our experience, the monitoring of telemedicine in patients with Heart Failure of high risk age (average age 80.4 years) will lead to an increased awareness of the disease, and the complete and specific training of the caregiver will become fundamental to build a solid social network system for the success of teledisease management.


With the development of big data and the continuous advancement of education informatization, the single lecture-based classroom teaching model no longer meets the development requirements of the society for the development of talent education and training. Under the environment of big data technology, how to innovate teaching models and talent training models becomes the focus of the current classroom teaching reform. This article aims to study the design of the college English bisection classroom teaching system based on big data. On the basis of introducing the bisection classroom, the basic theory of teaching system design and the design principles of the bisection classroom teaching system, the theoretical analysis and top-level design of the system login module and the teaching system that adaptively integrates teaching resources according to the status of college students are carried out. Finally, an experimental test of the college English split-class teaching system based on big data has been carried out. The test results show that the system can realize the core of system management, teaching resource release and dynamic configuration.

Bullous pemphigoid (bP) is a blister‐forming disease, probably of autoimmune nature. Its genetic background has not been established yet. Associations with other autoimmune diseases and, to some extend, with malignant tumors are noteworthy. The blisters are located subepidermally in the lamina lucida between the cytoplasmic membrane of the basal cells and the lamina densa of the basement membrane. The bP antigen, which is produced by basal cells, serves as an attachment factor and can be liberated into the blister fluid, probably by serine proteases from leucocytes. The formation of antigen‐antibody complexes is favoured afterwards. Freely circulating bP antibodies, mostly of the IgG class, are fixed in the skin tissue in vivo and in vitro and bind complement. Components of the classical complement pathway as well as of the amplification loop are activated locally in the skin tissue and fixed. The content of immune complexes is increased in the serum and in the blister fluid. They partially consist of specific bP antigen‐antibody complexes. The determination of the entire bP antibody titer (after immune complex splitting) correlates well with the clinical course of the disease.


The first referee method of analysis (a method of known accuracy) in clinical chemistry has been developed through the cooperation of scientists from the National Bureau of Standards and eight clinical chemistry laboratories. Subject to some limitations discussed in the text, calcium in serum can be determined by the referee method to within ±2% of the "true or absolute" value. The complete protocol, based on an atomic absorption spectrometric procedure, is described in detail.


While superluminal phenomena are not empirically substantiated, they present an intriguing hypothetical case. For this speculative framework, the Lorentz transformations would necessitate a revision: instead of the standard γ(x−vt), the absolute value of x′ ought to be expressed as γ(vt−x), because if v were to exceed c, then the interval vt traversed by the superluminal frame S′ would surpass the distance covered by light. Under the postulates of relativity, the subluminal scenario leads to the conventional Lorentz factor. Meanwhile, the superluminal scenario introduces an alternative transformation factor that accounts for the presence of the speed of light (c) barrier. This factor is also invariant within Minkowski spacetime, meaning it symmetrically preserves spacetime intervals. The details of this derivation become more evident when using a reverse coordinate system. This result is not, per se, evidence for the existence of superluminal phenomena, but it does allow us to speculate with a new argument about the possibility of their existence.

The world production of grapes is presently 69 million tones out of which India accounts for 2.2 million tonnes of grapes making a share of 1.51per cent of the world pro duction and 3 per cent of the total fruit production in the country. Area under this fruit has been increased up to 50 per cent and its production up to 71per cent from our country in last decade (1994 -2004) due to the economic importance of this fruit. Gr ape (Vitis vinifera L) cultivation is one of the remunerative farm enterprises in India. The processing of this fruit in our country is very less as compared to the traditional grape growing countries in the world where more than 80 per cent of the production is processed in the form of wine, raisin and juice. There are 16 bi products made from grapes viz. raisin, grape juice, squash, syrup, jam, jelly, vinegar, wine, pickles, chocolates, tartaric acid, oil, cattle feed, tannin, etc. The processed productsviz. wine; raisins and grape juice are the most popular products from grapes in all over the world. Raisins are the second most important product of the grapevine, wine being the first. The raisin trade in international market is increasing day by day. USAis the largest raisin producer in the world. India was placing 3rd in the world after USA and Turkey. In 2007 � 08 the raisin production of India was 156150 MT and 172900 MT in 2012 � 13. But it is clear that Raisin Industry in India facing several difficulties and problem such as climatic change, storage facilities, global financial situation and marketing strategy.The present investigation an attempt is made to study the marketing assessment of raisins with their production consumption and marketing of raisins industry in India. Secondary data have been used and basic statistical techniques are applied for the calc ulations. Raisins are mostly produced in Sangli, Solapur and Nasik districts of Maharashtra, Bijapur district in Karnataka, and some parts of Tamil Nadu, Andhra Pradesh and Punjab in India.

The above demonstrates that The development of distributed systems is currently a broad field and that its creation is of Great importance. Nevertheless, it is not well established in our region and a methodology is Therefore necessary to develop distributed applications with quality that will provide tools To engineers and small and medium-sized companies that develop software and allow for Better ways to implement distributed projects in software development.


GALEX Spectroscopic observations in the Far UV and in the Near UV are complemented by Mid‐/Far‐IR data from ISO to analyze a sample of galaxies in the ELAIS S1 field. We show that the FUV‐NUV cannot be used as a proxy for the UV slope β beyond a redshift z = 0.10 – 0.15. In addition, we estimate the UV dust attenuation from the FIR/FUV dust ratio and we compare it to the UV slope β which was proposed as a dust attenuation estimator. For this sample of MIR‐selected galaxies, we find a large dispersion and the dust attenuation estimated from β could be wrong by several magnitudes.


Abstract:An analysis of the Love Parade, the famous Berlin techno music festival, illuminates the city's cultural history and political economy in the 1990s. The article reconstructs the techno playworld built by fans around music, dance, and drugs, yet suggests that this underground scene ultimately contributed to official efforts to promote a "New Berlin" in the 1990s. City boosters, inspired by neoliberal urban development policies, appropriated the festival in ways that concretized Berlin's global reputation as Europe's "party capital" and helped resolve the city's post-reunification economic crisis, albeit in ways that did little to address gentrification or income inequality.


In recent years, digital platform forums where question and answers are being discussed are attracting more number of users. Many discussions on these forums would be repetitive nature. Such duplicate questions were provided by Quora as a competition on Kaggle. It is observed that the dataset provided by Quora, requires many modifications before training machine learning models to obtain a good accuracy. These modifications include feature extraction, vectorization and tokenization after which the data is ready for training desired models. While analyzing each model after prediction, it gives plenty of information about its efficiency and many other factors. Later, these information of different models are compared and helps to choose the best model. These models later can be combined and used as a single model with best accuracy. In this paper, a Machine Learning model which will predict duplicate questions is proposed


Creeping clover (Trifolium repens L.) is one of the best crops for creating meadow and pasture agrophytocenoses of long-term use. The biological features of this crop, such as durability, good yield, resistance to grazing, high leafiness, along with good feed quality indicators, its high protein nutritional value, make it indispensable when creating pastures not only in Russia, but also abroad. Creeping clover is one of the main components of grass mixtures for improving pastures and developing fallow lands; it is also an excellent phyto-meliorative crop that restores soil fertility. The most important problem of creeping clover seed production is harvesting due to the short stature of pasture varieties. Therefore, it is recommended to grow creeping clover for seeds in a mixture of grass together with cereal components such as perennial ryegrass, reed fescue, meadow fescue, etc. Due to the use of biological nitrogen of the legume component, energy consumption for the production of 1 kg of cereal grass seeds is reduced by 20–30% in comparison with uncoverless single-species crops. In addition to clover seeds, growing in grass mixtures allows you to get high yields of grass seeds in the second year of use without the use of nitrogen fertilizers.

Objective To observe the lipid accumulation in alveolar type Ⅱ epithelial cells(ATⅡ) A549 under high lipid condition and investigate the effect of inflammation on the accumulation as well as the possible mechanism.Methods A549 cells were divided into four groups.The cells in high lipid,inflammation and combined treatment groups were treated with 100 μg / ml LDL,300 ng / ml LPS and 100 μg / ml LDL + 300 ng / ml respectively,while those in control group were untreated.The lipid accumulation in cells were observed by oil red staining 24 h after treatment,while the transcription levels of sterol regulatory element binding protein 2(SREBP 2),3-Hydroxy-3-methlglutary 1 coezyme A(HMGCoA) reductase and low-density lipoprotein receptor(LDLr) mRNAs by real-time PCR,and expression levels of SREBP2,LDLr and ATP-binding cassette sub-family A member 1(ABCA1) by Western blot.Results The lipid accumulation in cells in combined treatment group was severer than those in other three groups.Compared with those in control group,the transcription of SREBP2,HMGCoA reductase and LDLr mRNAs in high lipid group decreased by(0.54 ± 0.09),(0.51 ± 0.06) and(0.34 ± 0.06) folds respectively(P 0.05).However,the down-regulation levels of mRNAs of various genes in combined treatment group were lower than those in high lipid group.The changing tendencies of SREBP2 and LDLr protein expression levels were basically consistent with those of transcription levels of the corresponding genes.The ABCA1 protein expression level in high lipid group increased by(2.78 ± 0.38) folds as compared with that in control group,However,the up-regulation level of ABCA1 expression in combined treatment group was lower than that in high lipid group.Conclusion Inflammation exacerbates lipid accumulation in alveolar type Ⅱ epithelial cells partly due to the disruption of SREBP2-LDLr / HMGCoA reductase pathway-mediated intracellular lipid homeostasis.


The authors describe a family of BiCMOS circuits for use in the sequence detection electronics of a magnetic recording channel. The discussion focuses on a class of analog BiCMOS circuits that implement the arbitration function. Several BiCMOS analog arbitration circuit topologies were evaluated. General design equations were derived for each topology in terms of power consumption. These equations were used to design circuits. The performance of these circuits was evaluated and compared to the predictions. Simulation and experimental results confirmed the design equations. The end result is a family of BiCMOS metric arbitration circuits for an analog implementation of a maximum likelihood sequence detection (MLSD) algorithm.<<ETX>>


Abstract We present a framework for 3D hand gesture design and modeling. We adapted two different pattern matching techniques, Dynamic Time Warping (DTW) and Hidden Markov Models (HMMs), to support the registration and evaluation of 3D hand gestures as well as their recognition. One key ingredient of our framework is a concept for the convenient gesture design and registration using HMMs. DTW is used to recognize hand gestures with a limited training data, and evaluate how the performed gesture is similar to its template gesture. We facilitate the use of visual sensors and body sensors for capturing both locative and inertial gesture information. In our experimental evaluation, we designed 18 example hand gestures and analyzed the performance of recognition methods and gesture features under various conditions.

We address the problem of trajectory-tracking and path-following control design for underactuated autonomous vehicles in the presence of possibly large modeling parametric uncertainty. For a general class of vehicles moving in either two or three-dimensional space, we demonstrate how adaptive switching supervisory control can be combined with a nonlinear Lyapunov-based tracking control law to solve the problem of global boundedness and convergence of the position tracking error to a neighborhood of the origin that can be made arbitrarily small. We also show how these results can be extended to the path-following problem, in which the vehicle is required to converge to and follow a path, without a special temporal specification, and once in the path, to satisfy a desired dynamic behavior. We illustrate our design procedures through two vehicle control applications: a hovercraft (moving on a planar surface) and an underwater vehicle (moving in three-dimensional space). Simulations results are presented and discussed.


The creation of tangible copies from a work of art that is publicly displayed had always been a rare practice, until some recent cases attracted huge media attention. Zaha Hadid's Wangjing Soho being pirated in Chongqing and the Chinese copy of the UNESCO-protected Austrian town of Halstatt have officially marked the entrance into the age of repeatability for architecture. This article reads this message through the lens of copyright law and introduces the category of "public art" as copyright subject matter. In particular, it examines the underpinning of private and public interests and suggests that, as public art is born to be displayed in public spaces and to "exist" in a single copy, the author–owner–society relationship becomes exceptionally puzzling. It is this last relationship that modifies how architecture is protected under copyright law and how, therein, the balance between private and public interest is struck.


A survey, based on the domain concept, is given of the outstanding features of the magnetic processes which may play a part when a ferromagnetic material, in particular iron or silicon-iron, is exposed to fields of weak or moderate intensity. The effects of closure domain configurations on the shape of the hysteresis loop and the effects of domain nucleation and growth in determining the magnetic properties of a material are discussed, both qualitatively and quantitatively, in the light of the results of Bitter figure and magnetothermal experiments; and the importance of the results to a proper understanding of basic magnetic phenomena, such as coercivity is discussed.


ABSTRACT Soil microorganisms are of paramount importance for crop yield. This study aimed to evaluate the effect of potassium chloride doses associated with two bioactivation sources on soybean yield and soil microbial activity. The experimental design was randomized blocks, arranged in a 5 x 2 factorial scheme, with four replications, being the first factor potassium doses (0, 30, 60, 90 and 120 kg ha-1 of K2O), using potassium chloride as a source, and the second factor soil bioactivation products: Penergetic (250 g ha-1) and Efficient Microorganisms (EM) (1:250), with 250 L ha-1 of spray volume. The KCl doses affected the soil microbial activity, while the soil bioactivating sources with the potassium chloride doses did not show significance for the leaf potassium content and soybean yield. K2O doses higher than the maintenance dose for the soybean crop with EM negatively influenced the soil microbial biomass. The EM bioactivator associated with the maintenance dose of K for the soybean crop (60 kg ha-1) is the most appropriate treatment for soil microbial activity, as it is the condition that presents the most stable environment and the highest microbial efficiency.


Here we will follow some of the presentation from Werner, Manby, and Knowles. 1 Density fitting is a way to approximate the usual two-electron integrals, (pq|rs) = dr 1 dr 2 φ p (r 1)φ q (r 1) 1 r 12 φ r (r 2)φ s (r 2), (1) where we have assumed real orbitals. We may also consider this electron repulsion integral as the repulsion between two generalized electron densities,


Introduction: Understanding neural mechanism of communication between human and machine has become more interesting research issue in last few decades. One of the most motivating purposes is to help the people with motor disabilities. This excites researchers to work on the interaction between brain-computer-interfacing (BCI) systems, which in turn needs a fast and accurate algorithm to decode the commands in the brain or electroencephalogram (EEG) signals. EEG signals are very noisy and contain several types of artifacts, so it would be very important to use efficient methods to train the BCI system. Aims and Goals: The goal of this project is to train an intelligent system based on the information in the sample EEG data. This system is going to predict the person's intention in future experiments with new EEG data. Finally, this project can be used in controlling a moving object like a robot, a wheelchair, or many other devices. Data Acquisition and methods: In this project, we are working with the EEG signals taken from 20 subjects thinking about English vowels \a\, \e\, \i\, \o\, and \u\. This means we can define only 5 clusters, which contain all signals with similar features. We are going to use part of the signals for training and the rest for testing. In training section, we have to first preprocess the data, and then categorize it into 5 clusters. Robust Principle Component Analysis (PCA) helps us to analyze the data to extract the features. Afterwards based on principle component features of signals, we employ a Hidden Markov Model (HMM) classifier to send similar signals to the same cluster. As EEG data is a randomly variant signal, we are using Hybrid HMM classifier for classification of EEG pattern. Our Initial results are promising in robust understanding of auditory command, which is been explored from EEG pattern analysis.


Deep neural networks have become more and more relevant for vision systems, for object detection and classification in industrial fields, such as robot navigation, monitoring and tracking. For such applications, vision systems have to be robust to environment conditions, occlusions and very accurate, as for bin picking. In this paper, we evaluate the performances of deep learning object detection neural networks in HALCON software, by investigating the uncertainty of bounding box position for object detection and the impact of disturbances. In this study, results evidenced the increase of bounding box uncertainty and the reduction of confidence of neural networks when disturbances are introduced, as well as the increment of uncertainty, when confidence lowers. When errors are introduced in labeling, the uncertainty of the bounding box position becomes higher, but lower than the error introduced.


Abstract Lessons Learned. Using a randomized crossover design and continuous variables such as change in hearing threshold and biomarkers of acute renal injury as short‐term endpoints, it was determined that pantoprazole, an organic cation transporter 2 inhibitor, did not ameliorate cisplatin‐associated nephrotoxicity or ototoxicity. Cystatin C is a robust method to estimate glomerular filtration rate in patients with cancer. Using a patient‐reported outcome survey, all patients identified tinnitus and subjective hearing loss occurring "at least rarely" after cycle 1, prior to objective high‐frequency hearing loss measured by audiograms. New therapies that improve outcome with less acute and long‐term toxicity are needed. Background. Organic cation transporter 2 (OCT2), which is a cisplatin uptake transporter expressed on renal tubules and cochlear hair cells but not on osteosarcoma cells, mediates cisplatin uptake. Pantoprazole inhibits OCT2 and could ameliorate cisplatin ototoxicity and nephrotoxicity. Using a randomized crossover design, we evaluated audiograms, urinary acute kidney injury (AKI) biomarkers, and glomerular filtration rate (GFR) estimated from cystatin C (GFRcysC) in patients receiving cisplatin with and without pantoprazole. Materials and Methods. Cisplatin (60 mg/m2 × 2 days per cycle) was administered concurrently with pantoprazole (intravenous [IV], 1.6 mg/kg over 4 hours) on cycles 1 and 2 or cycles 3 and 4 in 12 patients with osteosarcoma (OS) with a median (range) age of 12.8 (5.6–19) years. Audiograms, urinary AKI biomarkers, and serum cystatin C were monitored during each cycle. Results. Pantoprazole had no impact on decrements in hearing threshold at 4–8 kHz, post‐treatment elevation of urinary AKI biomarkers, or GFRcysC (Fig. 1, Table 1). Histological response (percent necrosis) after two cycles was similar with or without pantoprazole. All eight patients with localized OS at diagnosis are alive and in remission; three of four patients with metastases at diagnosis have died. Conclusion. Pantoprazole did not ameliorate cisplatin ototoxicity or nephrotoxicity. The decrease in GFRcysC and increase in N‐acetyl‐ß‐glucosaminidase (NAG) and creatinine demonstrate that these biomarkers can quantify cisplatin glomerular and proximal tubular toxicity. OCT2 inhibition by pantoprazole did not appear to alter antitumor response or survival.


This paper describes a new method for measuring the thermal diffusivity of liquid samples through inverse photopyroelectric detection measurement. It is proven that thermal diffusivity values can be obtained with both amplitude signals and phase signals in a low frequency range. At around 3 Hz, these values are found to correspond to their theoretical values. We experimentally prove that the piezoelectric effect, which films are known to exhibit, is negligibly small compared with the photopyroelectric effect.


The methods of Granger causality estimation and co-integration analysis were used to test the relationship of China's energy consumption and economic growth based on the data from 1980 to 2007.The results showed that there was a single-direction causality from economic growth to the energy consumption.In addition,there was a stable equilibrium relation between China's energy consumption and economic growth in the long-run.The energy supply constraint on economic growth was obvious.


To understand the development progress and relevant Frontier research of urban green space carbon sequestration, based on the core databases such as Web of Science, CiteSpace software, and bibliometric analysis methods were used to analyze the research status. The results showed that the number of papers on urban green space carbon sequestration research was on the rise. China and the United States had closer cooperation from the perspective of international cooperation institutions. Peking University, the Chinese Academy of Sciences, and the US Forest Service made the greatest contributions to this research field. Analyzing the keywords and the literature co-citation map, it was inferred that the hot keywords of future urban green space carbon sequestration research include carbon sequestration, ecosystem services, and climate change. It was found that carbon sequestration of urban green space ecosystems research primarily focuses on the correlation between urban green space and ecosystem services, and UGS carbon sequestration accounting and urban green space management. Finally, two perspectives were proposed: 1) Urban green spaces diversified ecological benefits are achieved through the function of carbon sequestration, and 2) Urban green space carbon sequestration accounting and urban green space management promote the development of urban green space. An overview of the international progress and basic state of urban green spaces and carbon sequestration theme research is presented in this paper, Additionally, it provides valuable references for future research and helps gain a comprehensive understanding of this field of research.


We consider the asymptotic spectral distribution of Hermitian Toeplitz matrices {Tn}n=1∞ formally generated by a rational function h(z) = (f(z)f*(1/z))/(g(z)g*(1/z)), where the numerator and denominator have no common zeros, deg(f) < deg(g), and the zeros of g are in the open punctured disk 0 < |z| < 1. From Szego's theorem, the eigenvalues of {Tn} are distributed like the values of h(eiθ) as n → ∞ if Tn = (tr-s)r,s=1n, where {tl}l=-∞∞ are the coefficients in the Laurent series for h that converges in an annulus containing the unit circle. We show that if {tl}l=-∞∞ are the coefficients in certain other formal Laurent series for h, then there is an integer p such that all but the p smallest and p largest eigenvalues of Tn are distributed like the values of h(eiθ) as n → ∞.


Black hole mass,along with the ratio of the accretionrate to the Eddington accretion rate,is a fundamental parameter of active galactic nuclei(AGNs).Using Xie's method of the black mass estimate,we developed our sample and estimated the black hole masses represented by MH for 21 blazars.We compare 21cases for each of which the relevant black hole mass has been also estimated by the MBH-σ correlation method,which is represented by Mσ.And we find that(1)MH are systematically lower than Mσ,but the differences between Mσ and MH are very small for most of the sources;(2) there is a significant correlation between Mσ and MH,the correlation coefficient r=0.823 with chance probability p~1.0×10-4.Based on these properties mentioned above and the standard model of AGNs,we prove that the nature of the systematical difference between Mσ and MH is that Mσ represents the mass in broad emission line region(r≤rb),while MH represents the mass in the continual emission region(r≤ra and rarb) which is near the innermost stable orbit around the black hole.That is,Mσ would be overestimated.From Mσ,we calculate the central black hole mass again,which is indicated by M*H,and find that M*H is almost equal to the correspondent MH.


It is important to map the large-scale matter distribution in the local Universe for cosmological studies, such as the tracing of the large-scale peculiar velocity flow, the characterisation of the environment for different astronomical objects, and for precision measurements of cosmological parameters. We used X-ray luminous clusters to map this matter distribution and find that about 51% of the groups and clusters are members of superclusters which occupy only a few percent of the volume. In this paper we provide a detailed description of these large-scale structures. With a friends-to-friends algorithm, we find eight superclusters with a cluster overdensity ratio of at least two with five or more galaxy group and cluster members in the cosmic volume out to z = 0.03. The four most prominent ones are the Perseus-Pisces, the Centaurus, the Coma, and the Hercules supercluster, with lengths from about 40 to over 100 Mpc and estimated masses of 0.6 - 2.2 10^16 Msun. The largest of these structures is the Perseus-Pisces supercluster. The four smaller superclusters include the Local and the Abell 400 supercluster and two superclusters in the constellations Sagittarius and Lacerta. We provide detailed maps, member catalogues, and physical descriptions of the eight superclusters. By constructing superclusters with a range of cluster sub-samples with different lower X-ray luminosity limits, we show that the main structures are always reliably recovered.


Competency development is important for every employee and should be empowered for them. Competency development through training consists of classical training and non-classical training. One form of non-classical training is independent learning and self-development through online learning, such as Massive Open Online Courses (MOOCs). The purpose of this research is to figure out the learning process either before and after the development of MOOCs and to develop an information system for training and independent learning as one feature of LMS Banten Ceria in the form of a Massive Open Online Course (MOOC) as an online learning platform with the principle of independent learning or self-directed learning in order to support the Corporate University program in the Province of Banten. This research has a mixed-methods design that blends qualitative and quantitative methodologies. The 4D Thiagarajan model is used in this study, along with research and development methodologies. The result show that MOOCs are effective in developing the competencies of the civil apparatus in the Province of Banten. The difference in average between the pre-test and post-test scores is 20 points. The learning process after using MOOCs shows improvements in knowledge and competence.  Hence, the system of online learning will support the BPSDMD Banten Provincial Program as it becomes a corporate university.
Keywords: Development MOOCs, Design MOOCs, Civil Apparatus Competence


A new approach is proposed for calibrating hydraulic network models. This procedure uses a nonlinear optimization algorithm along with a standard, off-the-shelf, network solver. Pipe roughness is adjusted until simulation results agree with the values observed in the field. To achieve realistic calibrated roughness values, the objective is to minimize the sum of the squares of the differences between the calibrated and initial pipe roughness estimates, under a set of constraints determined from a sensitivity matrix. The algorithm is applied to a sample network, and the resulting calibrated network is tested under different loading conditions.

Objective
To explore the application of detail nursing in the treatment of varicocele with adenosine triphosphate and testicular artery-sparing microscopic varicocelectomy and its effect on sex hormone.

Methods
100 cases of varicocele were treated with adenosine triphosphate and testicular artery-sparing microscopic varicocelectomy in our hospital from March, 2016 to March, 2018. They were randomly divided into an observation group (n=50) and a control group (n=50). The observation group received detailed nursing, while the control group received routine nursing. The duration of hospitalization, the incidence of complications, and the degree of satisfaction with nursing care were observed in the two groups. The nursing effects were compared between the two groups.

Results
The hospitalization time was shorter and the scores of Glasgow coma evaluation scale and nursing quality were higher in the observation group than in the control group, with statistical differences (all P<0.05). The incidence of complications was 4% in the observation group, and was 16% in the control group (χ2=4.000, P=0.046).

Conclusion
The application of detailed nursing measures in the treatment of varicocele with adenosine triphosphate and testicular artery-sparing microscopic varicocelectomy is of great significance for the patients' quality of life, so it is worth being clinically generalized.
