[ "Introduction {#sec1-1}\n============\n\nAfter respiratory infections, urinary tract infections (UTIs) as one of the most common bacterial infections are considered human. ", "Several studies suggest that Gram-negative bacilli, including *Enterobacteriaceae* bacteria family, are the most common microorganisms in the appearance of UTIs. ", "In the meantime, *E. coli is causing more than 81% of cases of UTIs*;\\[[@ref1][@ref2]\\] afterward, *Staphylococcus saprophyticus, Klebsiella, Enterobacter, Proteus*, and *Enterococci* have identified as the causes of UTIs.\\[[@ref3]\\] Quick and accurate diagnosis of UTI is very important to shorten the course of illness, as well as to prevent disease progression toward upper UTIs and renal impairment.\\[[@ref4]\\] Resistances to antibiotics in different parts of the world due to genetic changes in strains, diversity in the use of antibiotics, and division in the availability to broad-spectrum of new antibiotics are different.\\[[@ref5]\\] In many infectious diseases including UTIs, a physician needs to start the treatment before a definitive diagnosis of infection cause and antibiogram; therefore, to administer the appropriate antibiotic, the physician must have sufficient information about the probable cause of infection and antibiotic susceptibility;\\[[@ref6]\\] hence, UTI agents and their antibiotic resistance are identified in each region to start treatment before culture and antibiotic sensitivity test results.\\[[@ref5][@ref7]\\] Studies to identify the pathogens responsible for UTIs and antibiotic resistance are significant to their specific therapy to eradicate the infectious agent.\\[[@ref8][@ref9]\\] According to the numerous studies in the field of bacterial drug resistance patterns of UTIs, for validating the results of this study to give more precise and valid results, the current study is carried out through systematic review and meta-analysis.", "\n\nMethods {#sec1-2}\n=======\n\nA database was built for the most common resistance pattern of bacteria that causes UTIs in Iran from 1991 to 2015 using internal and external databases, including Scientific Information Database, Magiran, IranDoc, IranMedex, MedLib, PubMed, Web of Science, Scopus, and Google Scholar. ", "Search was limited to research papers about the most common bacterial causing UTIs and their antibiotic resistance patterns that have published in Persian and English magazines. ", "The keywords, titles, and abstracts were used by Boolean operator assistance. ", "Keywords involved are UTIs, Gram-negative bacteria, Gram-positive bacteria, antibiotics, and antibiotic resistance. ", "Likewise, titles and search results were evaluated and their suitability was determined for potential inclusion in the study. ", "Furthermore, the references of selected articles were examined. ", "Related studies in the list of references for inclusion in the study were selected.", "\n\nInclusion and exclusion criteria {#sec2-1}\n--------------------------------\n\nAll cross-sectional or group studies were considered in relation to antibiotic resistance patterns of bacteria that cause UTIs. ", "Study selection for inclusion in the assessment was done in three stages based on papers review: title, abstract, and full text. ", "In some cases, due to ambiguity in the results of a study, the author should be contacted by for more information. ", "Related studies involved the prevalence of bacteria causing UTIs and antibiotic resistance pattern. ", "Studies excluded from the analysis in each of the following reasons: studies that had insufficient information, studies not included in epidemiological studies, studies not included in cross-sectional studies, and studies that have relation with other infections than UTIs. ", "Furthermore, overview studies, summary of congresses, studies published in other languages except for Persian and Latin, systematic studies and meta-analyses, and repetitive publications were excluded from the analysis.", "\n\nData extraction {#sec2-2}\n---------------\n\nThe data extracted from all studies were first author, publication year, study year, study location, sample size, average and age group, gender, type of insulation, urinary pathogen prevalence, bacterial factors, resistance to different antibiotics, antibiotic susceptibility test methods, and antibiotics susceptibility report criteria \\[[Table 1](#T1){ref-type=\"table\"}\\].

", "This method teaches the use of two iris plates, one on each side of the traction rollers, to tilt the axis of rotation of each of the rollers. ", "However, the use of iris plates can be very complicated due to the large number of parts that are required to adjust the iris plates during transmission shifting. ", "Another difficulty with this transmission is that it has a guide ring that is configured to be predominantly stationary in relation to each of the rollers. ", "Since the guide ring is stationary, shifting the axis of rotation of each of the traction rollers is difficult.", "\nOne improvement over this earlier design includes a shaft about which an input disc and an output disc rotate. ", "The input disc and output disc are both mounted on the shaft and contact a plurality of balls disposed equidistantly and radially about the shaft. ", "The balls are in frictional contact with both discs and transmit power from the input disc to the output disc. ", "An idler located concentrically over the shaft and between the balls applies a force to keep the balls separate so as to make frictional contact against the input disc and output disc. ", "A key limitation of this design is the absence of means for generating and adequately controlling the axial force acting as normal contact force to keep the input disc and output disc in sufficient frictional contact against the balls as the speed ratio of the transmission changes. ", "Due to the fact that rolling traction continuously variable transmissions require more axial force at low speed to prevent the driving and driven rotating members from slipping on the speed changing friction balls, excessive force is applied in high speed and at a 1:1 ratio, when the input and output speeds are equal. ", "This excessive axial force lowers efficiency and causes the transmission to fail significantly faster than if the proper amount of force was applied for any particular gear ratio. ", "The excessive force also makes it more difficult to shift the transmission.", "\nTherefore, there is a need for a continuously variable transmission with an improved axial load generating system that changes the force produced as a function of the transmission ratio." ]

", "The need for these and other phenomenological parameters is one of the unsatisfactory aspects of this model. ", "Historically, renormalization provides the theoretical vehicle for the introduction of empirical mass parameters, although it requires the cancellation of large or infinite contributions. ", "Since then the Higgs mechanism, which gives the vector bosons a mass through spontaneous symmetry breaking, has been linked to the quark and lepton masses as well ([@Schwartz], p. 596). ", "However, this has not reduced the need for empirical (mass) parameters, either.", "\n\nThe question whether there exists an underlying theory that can predict these mass parameters is therefore as relevant as it was fifty years ago. ", "In the early days of string theory there were hopes that it could provide such predictions. ", "For example, in a basic text on string theory, Ref.", " [@Green], the authors state that: *a consistent unified theory of gravity and other forces might someday confront experiment through its implications for already measured quantities like the electron mass or the Cabibbo angle* ([@Green], p. 14). ", "However, this hope has gradually evaporated and the focus of string theory now lies elsewhere.", "\n\nIn this paper we show that a spatial QFT dressing theory can explain the existence of the three generations of quarks and may well form a basis for the prediction of the quark and lepton masses in terms of a few fundamental constants of nature. ", "Our description of dressing does not follow the usual route of incorporating dressing interactions in the scattering series, where they display singular behavior. ", "Rather, we use the quantized field equations for the quark and gluon fields to describe dressed quarks as self-contained spherical systems, consisting of a bare quark in interaction with the boson fields it generates itself. ", "In principle these dressing calculations should precede the application of the Standard Model, as they supply information on the properties of the Standard Model fermions and should tell us which self-interaction diagrams must be excluded from the scattering series. ", "This paper only deals with the fundamental task of constructing the self-contained dressed quark system, and does not address questions regarding the integration of this theory in the Standard Model framework. ", "This would be premature anyway until we have a fuller understanding of the dressing theory and its applicability.", "\n\nThe development of a local dressing theory requires various new QFT methodologies in order to deal with the use and quantization of the QFT field equations. ", "It also requires extensions beyond QFT to include certain consequences of general relativity, implying that QFT itself is unable to provide a fully fundamental basis for particle physics, as it requires empirical particle information.", "\n\nThe field equations in QFT are often dismissed as classical equations, a view which is reinforced by the fact in the classical limit $\\hbar \\rightarrow 0$ the action integral leads to $\\delta S=0$, which is precisely the condition that determines the (classical) Euler-Lagrange equations ([@Schwartz], p. 259). ", "However, it seems very strange that the field equations, which play such a central role in all other fields of physics and are essential for the derivation of Noether currents and energy conservation, would play such a limited role in QFT. ", "Dirac observed as much, when in 1979 he stated that *Methods based on the equations of motion (i.e. the field equations), so necessary for low energy physics have been largely abandoned as being intractable in QFT. ", "Yet if we believe in the unity of physics, we should believe that the same basic ideas universally apply to all fields of physics* [@Dirac_Eq_Motion]. ", "As we will see, quantization restores the field equations to their rightful place in QFT and also reveals their special - yet fundamental - role in QFT.", "\n\nThe currently popular Feynman path integral (FPI) quantization method seems not suitable here. ", "The QFT field equations are expressed in terms of a single space-time variable, in which case the notion of paths – which is so essential for FPI and other scattering approaches – does not enter in a natural way. ", "The reason for this limitation to a single space-time variable in the Lagrangian (and thus in the field equations) lies in the stringent demands of locality and relativity in QFT. ", "This restriction limits the applicability of the field equations, as they cannot deal with multi-particle problems in QFT, like they can in non-relativistic quantum mechanics (NRQM). ", "Hence, QFT scattering methods must also be used for multi-particle bound-state problems, implying that they have a much larger domain of validity in QFT than they do in NRQM. ", "An example is the case of lattice gauge calculations, where one deals with multi-particle bound-state problems, but which are based on FPI ([@Schwartz], p. 252). ", "However, this does not mean that the FPI is universally applicable. ", "The dressing of a single bare elementary particle is a bound-state problem that still can – and also has to – be dealt with through the quantized field equations. ", "This conclusion is rigorously confirmed by the operator formulation of the field equations, which yield an exact quantum solution which excludes any multi-particle components in the state vector, so that this approach is uniquely equipped to deal with the dressing problem in QFT.", "\n\nThe natural tool for carrying out quantization for this problem is canonical quantization, as it emphasizes the particle - rather than the wave - aspects. ", "By adapting this method to the (discrete) bound-state case we are led to the Wigner-Jordan rules for the creation and annihilation operators, which refer to the (initially unknown) quark bound-state wave functions. ", "After the quark fields are thus expanded, consistency demands that the gluon fields are also expanded in these operators, now multiplied with unknown gluon amplitudes. ", "The non-linear field equations then generate higher-order operator terms, so that the fields ultimately turn into infinite sums of products of creation and annihilation operators, multiplying amplitudes with an ever increasing number of indices. ", "This appears to make the construction of a closed solution an impossible goal. ", "However, certain patterns, which appear to be common between the lowest-order equations, suggest an operator solution with an appealingly simple structure. ", "Upon further examination the correctness of this exact operator solution of binomial form can be confirmed. ", "Its properties can easily be identified, the main one being that it eliminates any multi-particle admixtures in the state vector (this limitation holds separately for particles and anti-particles). ", "Hence, the field equation formulation determines its own domain of applicability, namely the dressed quark system characterized by a single quark state vector.", "\n\nUsing this operator solution one can factorize out the creation and annihilation operators from the field equations, reducing it to a set of coupled non-linear c-number differential equations. ", "The operator solution also ensures connectivity, so that only physically meaningful sequences of terms survive in the reduced field equations. ", "The extensive exploitation of self-consistency constraints and explicit and implicit symmetries enable a series of further simplifications which eventually yield a set of one-parameter solutions of the gluon field equations, which in the limit $\\alpha_s\\rightarrow 0$ even are of analytic form. ", "Combining this result with the quantized Dirac equations constrains the solutions even further, leading to a discretization of the continuous set of solutions, so that eventually a set of four discrete solutions emerges. ", "One of these can be identified with the original bare quark state and would have been the only (trivial) solution had we started with $\\alpha_s= 0$. The other three are structural solutions which meet the criteria for dressed quarks.", "\n\nThis bound-state theory is better behaved than standard QFT, as it does not lead to infinite diagrams and even allows exact non-perturbative solutions (in the limit $\\alpha_s\\rightarrow 0$). ", "There is no need for gauge fixing terms in the Lagrangian, in fact maintaining the original form of the Lagrangian (apart from ordering issues) appears essential for obtaining analytic solutions. ", "The only infinite quantities that occur are the potentials (and in some cases their wave functions) which ensure the absolute confinement of the bare quark at a finite radius, thereby confirming the self-contained nature of the dressed state whose internal dynamics is insulated from the outside world.", "\n\nWhile certain complications of ordinary QFT are thus absent, there are new problems which need to be addressed. ", "These have to do with the presence of (infinite) products of amplitudes at the same space-time point. ", "In standard QFT such products lead to singularities and infinities, especially in expectation values. ", "These are usually removed by the ad hoc imposition of the normal product on these expressions (see [@Bogoliubov], p. 76 or [@Itzykson], p. 111). ", "The use of this tool has also been continued in string theory (see [@Green], p. 91). ", "However, in the dressing theory, which is characterized by (infinite) products of operators at the same point, this recipe fails and we need a more principled approach. ", "The resolution of this problem was discovered early in the development of the dressing theory. ", "It requires the imposition of the so-called $\\mathbb{R}$-product [@Ordering] on strings of anti-particle operators which share the same space-time variable. ", "This product plays an essential role in obtaining the correct structure of the operator equations and in the construction of the exact operator solution. ", "It also ensures that unphysical infinite terms are eliminated and physically important high order terms (which would be eliminated under the normal product prescription) are preserved in the resulting coupled differential equations. ", "The physical reason why the $\\mathbb{R}$-product must be imposed in QFT is that it eliminates the inherent bias towards particles in the calculation of expectation values. ", "It also plays an important role in other problems. ", "For example, it resolves the cosmological constant problem [@CC; @problem].", "\n\nAnother problem which needs to be addressed is the scale invariance of the field equations. ", "As mentioned earlier the physical scale can only be set after certain effects of general relativity are taken into account. ", "Finally, the negativity of the QFT energy (unacceptable in a scattering formulation, but here acceptable as it represents the binding energy of the bound state) must be countered by a positive vacuum energy to ensure the positivity of the dressed mass. ", "This vacuum energy is supplied by a miniature vacuum universe, again contained within the absolutely confined system.", "\n\nThe outline of the paper is as follows.

", "Finally, in Sec.", " \\[sec:conclusions\\] we summarize our results and discuss new opportunities to gain further insights in QFT and its unification with GR.", "\n\nHistorical perspective on the development of the dressing theory {#sec:Broad}\n================================================================\n\nIn the previous section we presented an introduction to the QFT dressing theory. ", "However, the original goal of this research effort was very different. ", "It might be instructive to present a brief history of this research path in order to understand how its ideas originated and developed, as they lead to quite a novel perspective on QFT, while the late emergence of this theory also deserves an explanation.", "\n\nIn the middle eighties we were involved in the field of bag theories ([@Hybrid],[@pion]), where nucleons are considered as an assembly of three quarks confined in a bag. ", "These theories were advanced by various groups, notably at MIT ([@MIT_Group], [@MIT], [@DeTar]) and Triumf [@Thomas], and had met with considerable success. ", "However, its main feature – the confining bag -– had a phenomenological character and was not derived from QCD. ", "Our goal was to find such a derivation. ", "Since we expected the non-linear nature of QCD to be essential for the derivation of the confinement potential, thereby inspired by the non-linear sigma model ([@non-linear; @sigma],[@sigma]), we started out with these non-linear field equations. ", "To make progress it was necessary to expand the quark field $\\psi$ in creation and annihilation operators [@CapeTown87]. ", "Also, the restriction to quark states - which was common in bag physics - was inadequate, and the anti-quark degrees of freedom needed to be included as well. ", "Self-consistency of the field equations then determined the operator form of the quantized gluon field.", "\n\nThe next important step was the introduction of the $\\mathbb{R}$-product, as this explained the mysterious minus signs which appeared necessary in the field equations, if these were to make sense in the presence of anti-particles. ", "Subsequently it was realized that this $\\mathbb{R}$-product is a necessary foundational element in QFT to counter the bias towards particles in expectation values.", "\n\nAs stated earlier, the main breakthrough came when we discovered the exact operator solution of the infinite set of coupled operator equations. ", "However, its main property, that the operator solution restricts the application domain to state vectors consisting of a single-quark, excludes its application to the bag model. ", "We had already found indications that certain many-body terms did not seem to fit the formulation and spoiled emergent patterns in the field equations. ", "We could also have been warned by a remark by one of the authors of the MIT bag model, Ken Johnson, who stated in 1975 that the internal quark structure of hadrons could not be related to particles, since that would restrict the description to a non-relativistic framework [@Johnson]. ", "These problems can again be attributed to the unique structure of the QFT field equations which depend on a single space-time variable. ", "Because of this they cannot accommodate the multiple variables typical of non-relativistic bound-state treatments of multi-particle systems.", "\n\nThe discovery of this limitation of the field equation approach caused an important U-turn in our research, as we now had to divert our attention from bag physics to the problem of the dressing of single quarks, thereby confronting the conventional treatment of dressing. ", "The transition to the dressing problem could proceed relatively quickly, as many of the essential ingredients – such as the quantization procedure and the $\\mathbb{R}$-product – had already been developed. ", "Nonetheless, the road towards the current theory was a long one, requiring many new conceptual steps.", "\n\nAlthough the original goal had to be abandoned to be replaced by an even more fundamental goal, our findings still bear relevance in the MIT bag context. ", "First, the effective confining mechanism for the first generation of (light) quarks is identical to the phenomenological one used in the MIT bag (except for the scale of course). ", "We find that the potentials are inversely proportional to the quadratic difference between the large and small component of the quark spinor $f^2-g^2$, so that the potential becomes infinite (absolutely confining) when $|f|=|g|$. But this is the same condition that defines the surface in the MIT bag model. ", "So our methodology demonstrates how such an infinite bag can arise from QCD. ", "The MIT bag model also required a volume background (vacuum) term to enable mass calculations, just like we do in our dressing theory. ", "This shows that the MIT group was able to postulate the main features of confinement purely on general physics grounds and intuition, although in the bag case it was meant to model the interaction between quarks in a colourless state, rather than the self-interactions. ", "Conversely, it shows that our formal dressing methods lead to a picture of dressed quarks that has as strong physical appeal. ", "Or to paraphrase Dirac’s comment a little: although the setting is totally different the emerging picture of dressed quarks again confirms the unity of physics and the universality of basic ideas in physics; in this case the spherical nature of the basic constituents of matter.", "\n\nFrom a historical point of view it is also interesting to mention that during the early developments of QFT there were intense discussions about the role of self-interactions, which are well described in the book by Schweber on QED [@SS]. ", "In ordinary quantum mechanics such interactions are excluded from the scattering series, however, in QFT the situation is more complex, as there are a multitude of self-interaction diagrams, some of which play an important role in the explanation of the Lamb shift. ", "This debate was settled in favour of the inclusion of all self-interactions - and thus dressing - in the scattering series, despite the singularities arising from this treatment. ", "However, the criticism on these infinities petered out after the introduction of renormalization. ", "The time was not ripe for the development of a local dressing theory anyway, as the nonlinear gauge theories had not yet been formulated and general relativity was not yet seen by many as a necessary ingredient in particle physics.", "\n\nWe must honour Dirac for still pursuing such goals at a time when most particle theorists were involved in developing QFT scattering theory and renormalization techniques. ", "In 1962 he tried to prove that the muon should be considered as an excited state of the electron by developing a spatial QED model of the electron [@Dirac_electron]. ", "This is exactly the philosophy which is supported by the results of the dressing theory. ", "He even went as far as to extend this theory to include the effects of gravity [@Dirac_electron_GR]. ", "A further motivation of Dirac was that the resulting finiteness of the electron might resolve the infinity problem in QFT, whose solutions he never accepted, as he considered the renormalization process unnatural [@Dirac_Renorm]. ", "Unfortunately these efforts were premature, but they attest to Dirac’s far-sighted physical intuition. ", "Remarkably, the link between particle physics units and cosmological parameters, which the dressing theory has uncovered, is also a link Dirac speculated on with his fascination for the recurrence of large numbers and ratios in physics, as expressed in his large number hypothesis [@DiracLarge].", "\n\nQuantization of the field equations {#sec:quantization}\n===================================\n\nIn this section we discuss the quantization procedure and the construction of the operator solution. ", "For some of the technical details we refer back to our earlier paper [@QuarkDressing], which dealt exclusively with the first generation.

", "We can also consider Eq.", " (\\[eq:mqtc\\]) as a testable working hypothesis, as it leads to concrete predictions for the quark masses.", "\n\nImposing Eq.", " (\\[eq:mqtc\\]) on Eq.", " (\\[eq:tc\\]) converts it into a self-consistent equation for $t_c$ or for the mass of the dressed quark. ", "Since the mass of the quark is much smaller than the two contributions in the RHS, there must be a nearly complete cancellation between the positive vacuum energy and the negative QCD energy. ", "This yields the identity: $$\\label{eq:tcreation}\nt_c=\\frac{9}{2}\\left(\\frac{G}{6\\pi \\epsilon}\\right)^{1/6}\\left(\\frac{x_0^{(n)}\\gamma^{(n)}}{\\delta^{(n)2}}\\right)^{1/3},$$ so that the quark mass $m_q^{(n)}$ is given by: $$\\label{eq:mq}\nm_q^{(n)}=\\frac{1}{9}\\left(\\frac{6\\pi \\epsilon}{G}\\right)^{1/6}\\left(\\frac{\\delta^{(n)2}}{x_0^{(n)}\\gamma^{(n)}}\\right)^{1/3}.$$ The quark mass is now expressed in terms of the fundamental physical constants $G$ and $\\epsilon$ and its order of magnitude is given by $$\\label{eq:scale}\n(6\\pi \\epsilon/G)^{1/6}= (3 \\Lambda/4 G^2)^{1/6}= 69.38 \\text{ MeV}.$$ Hence, the dressing formulation, in combination with the cosmological model, has provided a long-sought connection between cosmological parameters and particle physics. ", "This is exactly the result we were hoping for initially, though its realization looked a dim prospect for a long time. ", "To reach this stage required a number of large conceptual steps, which however now find strong support in this result.", "\n\nIf we now apply Eq.", " (\\[eq:tcreation\\]) and Eq.", " (\\[eq:mqtc\\]) to the light quarks ($x_0^{(1)}=2.04279$; $\\gamma^{(1)}=23/9$; $\\delta^{(1)}=0.6019$) we find that $m_q= 3.17$ MeV; a result first presented in Ref.", " [@QuarkDressing]. ", "This result is even more amazing than the order of magnitude estimate given above, since it lies right in the empirical range found in lattice gauge calculations, namely $3.8 \\pm 0.8$ MeV [@Lattice; @Quark; @masses]. ", "However, we view this further success as a bit fortuitous, as we would not expect such an accurate answer while having ignored the electroweak and Higgs interactions.", "\n\nApplying the same formulae to the second generation ($x_0^{(2)}=1; \\gamma^{(2)}=7/9; \\delta^{(2)}=1$) yields a mass of 8.38 MeV. Although this is considerably larger than the value obtained for the light quarks (by a factor 2.6), the result falls far short of the observed values.", "\n\nFor the third generation the limiting procedure $\\gamma^{(3)}\\downarrow 0$ leads to an infinite quark mass. ", "This may not be a bad initial result in view of the enormous quark masses for this generation. ", "Clearly, further binding is necessary to make $\\gamma^{(3)}$ positive and produce a finite mass. ", "Since the masses for the higher generations depend strongly on charge, accurate results can only be expected after the missing electroweak interactions are included.", "\n\nIn order to introduce electroweak and Higgs interactions in the dressing theory, one needs to formulate a basic Lagrangian without reference to the generation quantum number. ", "Because of the complexity of the electroweak interactions and the role of spontaneous symmetry breaking in the SM formulation, the reduction of the SM electroweak Lagrangian to such a basic form is not so straightforward as it was for QCD. ", "However, we have experimented with a simple Higgs interaction which does not refer to the generation quantum number. ", "Our tentative results suggest that the Higgs interactions are suppressed for the light quark case because of certain cancellations in the first generation solution. ", "If substantiated, this could be an explanation for the observation that the Higgs mainly interacts with the higher generations.", "\n\nApart from improvements in the dressing theory there may also be more conventional standard QFT scattering diagrams (external to the dressed state) which contribute to the effective quark mass, so that the quark masses we calculate cannot directly be compared to the observed ones. ", "As stated in the introduction, this paper does not address the integration of the theory in the SM framework, where questions of such additional contributions might arise.", "\n\nSummary and future developments {#sec:conclusions}\n===============================\n\nIn this paper we presented a theory of the dressing of bare quarks based on the solution of the quantized (QCD) field equations. ", "Using this approach we were able to prove that the gluon fields generated by the bare quark lead to the absolute confinement of the quark and gluon fields within a small spherical volume of Planck length dimensions. ", "With its ability to explain the existence of the three generations and its potential to predict the quark masses in terms of a few fundamental constants of nature, this theory could become an important foundation block for particle physics.", "\n\nThe success of this theory was crucially dependent on a number of theoretical discoveries and could only be completed after certain consequences of general relativity were accounted for and a vacuum background term – inspired by cosmology – was included.", "\n\nThe first important discovery was that the quantized operator equations, expressed in terms of creation and annihilation operators, admitted an exact operator solution. ", "This solution defined its own domain of applicability by limiting the allowed state vectors to single-particle quark states, thereby identifying the dressing problem as a unique problem in QFT that requires a unique methodology. ", "This result makes it more plausible why scattering methods in QFT have been so dominant from the start and why the dressing application has taken so long to be discovered, although this could also be due to the apparent conflict between small quark masses and their non-zero, but very small size.", "\n\nThe knowledge of the exact operator solution enabled the reduction of the quantized field equations to c-number equations. ", "This paved the way for further discoveries. ", "The reduced coupled field equations allowed three structural (eigen)solutions, which even survived in the limit $\\alpha_s\\rightarrow0$. Hence, the likely reason behind the existence of three generations of quarks was identified. ", "Within the dressed system the gluon interactions – though originally of vector type – translated in scalar, vector and tensor interactions. ", "Subsequently these potentials could be reduced to a single effective scalar potential, which gave the formal theory a strong physical appeal. ", "For example, the solutions displayed a strong similarity with the phenomenological MIT three quark bag.", "\n\nThe collapse of the dressed system with negative total energy could be prevented by including GR in the description, leading to a size of the order of Planck lengths. ", "However, this constrained the possible solutions to the problem of the construction of a vacuum term that – together with the negative binding energy – could be the basis for mass calculations. ", "Such a term would have to compensate for the enormous (negative) energy density of the dressed system. ", "The solution was to define a vacuum of cosmological signature. ", "After its introduction the quark masses became calculable and were found to lie in the MeV region, despite being a result of the cancellation of terms of the order of the Planck energy. ", "This demonstrated for the first time the important role of cosmological parameters in particle physics.", "\n\nThe dressing theory looks to open a new domain of applications of QFT which brings with it techniques that are more common in non-relativistic physics, such as the concept of discrete eigensolutions, normalized states, binding potentials and bound-state wave functions. ", "Aspects both new to QFT and non-relativistic quantum mechanics are the exact quantization techniques, the strong reliance on self-consistency and the dependency on a successful extension into general relativity and cosmology. ", "Many elements are still missing, such as the inclusion of electroweak and Higgs interactions, so there are ample opportunities for extensions and improvements whose predictions can be tested against the existing knowledge of elementary particles.", "\n\nThe powerful techniques and methodologies developed in the dressing theory, in particular the exact operator techniques, could also benefit the standard scattering applications in QFT and the SM. ", "To use them in the case of boson fields, one should expand these fields in bilinear (bare) quark-anti-quark operators interspersed if appropriate with the infinite operator $\\Lambda_\\infty$, just like we did for the dressing case. ", "Naturally, in the scattering case one should employ a continuous spectrum of plane waves (with the momentum shared equally between quark and anti-quark), rather than unknown discrete bound-state wave functions. ", "In such an expansion most physical properties of the fields are automatically built in. ", "By quantizing boson fields this way we were able to avoid the cosmological constant problem [@CC; @problem], maybe the most serious problem in the conventional quantization approach in QFT.", "\n\nIt also appears possible to extend this methodology to the lepton sector and thus explain the existence of three lepton generations. ", "We hope to discuss this extension in a further publication. ", "One of the important questions which need answering in this connection is why the neutrino masses are so tiny. ", "Like the large quark masses for the higher generations, the explanation of these small masses may well require additional conceptual steps and lead to new theoretical surprises. ", "However, the current theory has shown that it is no longer justified to consider these masses as empirical parameters, but rather as parameters which deserve a theoretical explanation.", "\n\nThe author acknowledges a discussion with Prof. Vincent Icke which contributed to the physical understanding of the energy results.

", "The identical kinetics for all of the responses, both inductive and suppressive, suggests that a common mechanism controls the expression of these genes. ", "These results indicate that vitamin A produces more sweeping changes in keratinocyte function than previously appreciated in that many and perhaps all keratins are modulated by vitamin A. Moreover, these responses are 10- to 100-fold less sensitive to retinoid than the process of envelope formation, suggesting that at least two sets of processes with different sensitivities to vitamin A are present in keratinocytes." ]

Density functional (DFT) calculations show a large central FS, surrounded by six small elliptical hole pockets [@DJS00], while angular-resolved photoemission (ARPES) measurements find the large pocket but do not see the smaller ones [@H-Y04; @MZH+03; @qian06; @yang05]. ", "The presence or absence of these small pockets drastically changes the response properties of the system, and a number of proposed superconductivity models depend on them [@MDJ+b; @mochizuki; @HIYN04; @kuroki]. ", "There are two basic ways to resolve the controversy: either the experiment is not representative of the bulk electronic states, or correlation effects beyond the DFT calculations qualitatively change the Fermiology. ", "The latter seems rather plausible, given the narrow width of the Co $t_{2g}$ bands and the fact that DFT fails to reproduce the nonmagnetic ground state for $x\\lesssim 0.7$. The effects of adding correlation have been recently addressed through DMFT calculations which account for both on-site Coulomb repulsion (Hubbard $U$) and local fluctuation effects (albeit not for long-wave-length ferromagnetic calculations, compatible with the observed at $x\\gtrsim 0.5$ magnetic interactions in this system). ", "Despite initial controversy [@ishida; @georges; @marianetti], it has been firmly established that DMFT calculations only agree with ARPES if the centroids of the the $a_{1g}$ and $e_{g}^{\\prime }$ Co $d-$bands are such that $\\epsilon _{a_{1g}}$ is higher than $\\epsilon _{e_{g}^{\\prime }}$, which would yield a positive splitting, $ \\Delta =$ $\\epsilon _{a_{1g}}-\\epsilon_{e_{g}^{\\prime }}>0$. If, on the other hand $\\epsilon_{a_{1g}}-\\epsilon_{e_{g}^{\\prime }} <0$ then the small hole pockets are preserved and even slightly enlarged.

", "In the several cases where we have compared our values of $\\Delta $ to those calculated from the Wannier functions of a three band model, we have found that the latter are always *more* negative than the values extracted directly from DFT.

", "This may have an effect on the onsite energy ordering, although we believe it will be quantitative, not qualitative. ", "An additional effect of this extent is a strong reduction of the Hubbard $U$ as compared to typical values for local $d$-orbitals in transition metal oxides.", "\n\nResults and Discussion\n----------------------\n\nWe first address the effect of the octahedral compression (trigonal distortion) that lowers the symmetry at the Co site and splits the $t_{2g}$ triplet into the $a_{{1g}}$ and $e_{g}^{\\prime }$ complexes. ", "Some previous works have assumed that the distortion destabilizes the $a_{1g}$ state [@korshunov; @kroll; @fcc04; @wang], while others assume oppositely that the $\ne_{g}^{\\prime }$ state is higher in energy [@zhou; @WKSM03b]. ", "We have examined this question from two points of view. ", "First, we have constructed a tight-binding model of a CoO$_{6}$ octahedron, including the three Co $t_{2g}$ orbitals and three $p$ orbitals on each of the six O atoms. ", "We have diagonalized the resulting matrix for both compressive and expansive distortions. ", "Using the canonical scaling of the $t_{dp\\sigma }$ and $\nt_{dp\\pi }$ parameters, namely $t_{dp\\sigma }=\\sqrt{3}t_{dp\\pi}$, we find that the compressive distortion, as seen in Na$_{x}$CoO$_{2}$ for all $x$, destabilizes the $e_{g}^{\\prime }$ state. ", "However, if the ratio of the two parameters were to be increased by approximately a factor of two, as has been seen in some cases [@CDW], the order of energies is reversed and the $a_{1g}$ state is destabilized. ", "Second, we have performed a full DFT calculation of $\\Delta $ as a function of the trigonal distortion. ", "We use a fictitious compound, $\ne^{-}$CoO$_{2}$, in which one electron per formula unit has been added to the CoO$_{2}$ compound to achieve the band-insulating state, analogous to NaCoO$_{2}$. The extra charge is compensated by a uniform positive background. ", "We use this technique, termed jellium filling, to eliminate the effects of the Na potential and of unequal band fillings, which we discuss in later section. ", "As can be seen in Fig. ", "\\[DC\\], octahedral compression always produces a positive $\\Delta $, *i.e.* the $a_{1g}$ state is raised above the $e_{g}^{\\prime }$. ", "This demonstrates that the scaling of $t\n_{dp\\sigma }$ and $t_{dp\\pi }$ is outside the canonical range and points to the importance of neighbors more distant than the surrounding O atoms.", "\n\nBy far the strongest factor determining the value of $\\Delta $ is the presence of ionized Na atoms in the intercalant plane. ", "The positive Coulomb field they produce serves to strongly shift the a$_{1g}$ orbital downward compared to the $e_{g}^{\\prime }$ orbital. ", "As seen in Fig. ", "\\[orb\\], the $a_{1g}$ orbital has a greater extent along the $z$ direction (c-axis of the crystal) and therefore penetrates further into the Na plane. ", "The resultant lowering of the $a_{1g}$ states is sufficient to shift the sign of $\\Delta $ from positive to negative. ", "Replacing the jellium filling discussed above with real Na ions (again one per formula unit), we find a negative shift of approximately 150 meV in $\\Delta $ for all trigonal distortions, as seen in Fig. ", "\\[DC\\]. ", "Because quantum chemical calculations account only for the filling effects of Na and neglect the electrostatic field produced by real ions, this shift is not present and $\\Delta $ is consequently found to be strongly positive. ", "Not surprisingly, when Na ions are located directly atop a Co ion ($2b$ site), the effect is stronger than when they are located equidistant between three Co ions ($2c$ site).", "\n\nThe final factor contributing to the size of $\\Delta $ is the non-uniform filling of the two band complexes. ", "For all levels of Na intercalation, the $ a_{1g}$ bands are less filled than the $e_{g}^{\\prime }$ bands. ", "At a critical filling of $x_{c}\\sim $ 0.67, the $e_{g}^{\\prime }$ complex becomes entirely filled, leaving holes only in the $a_{1g}$ bands. ", "The increased on-site Coulomb repulsion due to greater filling drives the $e_{g}^{\\prime }$ upward in energy compared to $a_{1g}$ bands. ", "In the absence of real Na ions (hence no positive interstitial Coulomb field) and without octahedral distortion, the calculated $\\Delta $ for CoO$_{2}$ is $-77$ meV, reflecting this multi-band effect. ", "We have calculated $\\Delta $ for Na$_{x}$CoO$_{2}$ and for $xe^{-}$CoO$_{2}$ (jellium filling) as a function of $x$, with all oxygen positions fixed to perfect octahedra. ", "For the jellium filled compounds, $\\Delta $ initially remains approximately constant and then increases dramatically at $x_{c}\\sim $ 0.67 where the $e_{g}^{\\prime }$ bands become entirely filled, as seen in Fig. ", "\\[multi\\]. ", "The Na$_{x}$CoO$ _{2}$ curve, on the other hand, decreases initially and then flattens out once the $e_{g}^{\\prime }$ complex is full. ", "In the former case, electrons are added to both $e_{g}^{\\prime }$ and $a_{1g}$ states at low $x$, pushing both complexes upward nearly equally. ", "Once the $e_{g}^{\\prime }$ holes are filled, all further electrons enter the $a_{1g}$ complex, pushing the $a_{1g}$ onsite energy up relative to $e_{g}^{\\prime }$ and causing $ \\Delta $ to increase. ", "The situation is more complex when real Na ions are added. ", "At low $x$, both $e_{g}^{\\prime }$ and $a_{1g}$, electrons are added to both complexes and on-site repulsion raises both energies together, but the increasingly positive Coulomb field created by adding Na ions pushes the $a_{1g}$ states downward. ", "$\\Delta $ therefore increases with $x$ as long as holes remain in both symmetry complexes. ", "After $x_{c}$, where additional electrons enter only the $a_{1g}$ complex, the positive Coulomb field acts oppositely to the increased on-site repulsion. ", "Apparently the magnitude of these two effects is approximately equal, as evidenced by the nearly constant $\\Delta $ at $x>x_{c}$.\n\n $x$ Na1 position Na2 position \n ------- -------------- -------------- --\n $0$ -80 meV - \n $1/3$ -100 meV -95 meV \n $2/3$ -114 meV -101 meV \n $1$ -77 meV -6 meV \n\n : $\\Delta \\equiv \\epsilon_{a_{1g}} - \\epsilon_{e_g'}$ values for full DFT calculations, including relaxation of the lattice parameters and ionic positions.

", "Having studied each of these factors individually, we proceed to calculate $\n\\Delta $ as a function of $x$, accounting for all factors simultaneously.

", "Their estimate for Delta at x=1 is also consistent with ours [@georges]. ", "It is clear that $\\Delta $ is a non-monotonic function of $x$, owing to competition between the various effects associated with Na filling, but that it remains negative for all Na content 0 $< x <$ 1.", "\n\nConclusions\n-----------\n\nThe crystal field splitting $\\Delta $ $\\epsilon\n_{a_{1g}}-\\epsilon_{e_{g}^{\\prime }}$ is known to be the parameter that controls the presence or absence of the controversial $e_{g}^{\\prime }$ pockets at the Fermi level in Na$_{x}$CoO$_{2}.$ Here we show that, within the DFT framework which is highly reliable for calculating one-electron parameters, $\\Delta $ is always negative and strongly so for low $x$. We have shown that this fact is mainly due to the electrostatic crystal field of Na as well as demonstrating that the O ligand field (octahedral distortion), in fact, leads to the opposite sign of $\\Delta .$ The explicit effect of ionized Na has been neglected or severely approximated in previous calculations, leading erroneously to positive values of $\\Delta $.

", "While all are Muslim-majority countries, the list — and the ban — do not include Saudi Arabia, Egypt, Jordan and numerous other Muslim-majority countries.", "\n\n(Zoeann Murphy/The Washington Post)\n\nAdditionally, all refu­gee admission and resettlement would be halted for 120 days — and until further notice, from Syria — while vetting procedures are reviewed. ", "Once restarted, annual refu­gee admissions from all countries would be cut from the currently authorized level of 100,000 to 50,000.", "\n\nAsked Wednesday about the draft, White House press secretary Sean Spicer said actions dealing with refugees and other U.S. admissions would be signed later in the week, and “as we get into implementation of that executive order, we will have further details.” ", "Trump’s “guiding principle,” he said, is to prevent entry to “people who are from a country that has a propensity for doing harm.”", "\n\nCivil rights and refu­gee advocates immediately expressed alarm over the policies, and said that the news has thrown groups that handle refu­gee resettlement and immigrant rights — including U.N. agencies — into disarray.", "\n\n“These actions taken by Donald Trump are tantamount to a Muslim ban,” Abed A. Ayoub, the legal and policy director for the American-Arab Anti-Discrimination Committee, said during a Wednesday conference call with refu­gee and immigrant advocates and journalists. “", "Regardless of how they try to frame it . . .

", "It had no security value; it really overwhelmed government offices and officials who were unprepared.”", "\n\nA key question for U.S. courts, if the order is challenged, will be whether the new policies exceed the reasonable boundaries of the president’s executive authority on immigration or violate portions of the Constitution, legal experts say.", "\n\nThe draft order instructs the U.S. government to screen visa applicants for their ideologies. “", "In order to protect Americans, we must ensure that those admitted to this country do not bear hostile attitudes toward our country and its founding principles,” the draft order reads.", "\n\nThe order says the United States should screen visa applicants to block access to those “who would place violent religious edicts over American law” and those who “engage in acts of bigotry or hatred” including “honor” killings, violence against women, and persecution on the basis of religion, race, gender and sexual orientation, a description that human rights groups say also appears to be geared toward Muslims, without naming Islam explicitly.", "\n\nJoanne Lin, the senior legislative counsel to the American Civil Liberties Union, said the wording “raises the prospect of ideological tests for admission to the U.S.” It could potentially be used to screen out critics of U.S. policy, and could violate Americans’ First Amendment right “to hear from speakers that oppose the government’s official views.”", "\n\nIn addition to questions about what they will do, whom they will see and how they will pay for a U.S. visit, visa applicants can be asked if they seek U.S. entry to engage in terrorism or other illegal activities, and whether they have committed or been convicted of crimes. ", "Those requesting immigrant or permanent residence status are also asked about Communist Party membership.", "\n\nThis article has been updated to correct the spelling of the last name of Joanne Lin, the senior legislative counsel to the American Civil Liberties Union." ]

", "This occurs due to three main interactions during late G1 phase. ", "The first is a result of mitogen stimulation though the ERK leading to the expression of the transcription factor Myc, which is a direct activator of E2F. The second pathway is a result of ERK activation leading to the accumulation of active complexes of Cyclin D and Cdk4/6 which destabilize Rb via phosphorylation and further serve to activate E2F and promote expression of its targets. ", "Finally, these interactions are all reinforced by an additional positive feedback loop by E2F on itself, as its own expression leads to production of the active complex of Cyclin E and CDK2, which further serves to lock in a cells decision to enter S-phase. ", "As a result, when serum concentration is increased in a gradual manner, most mammalian cells respond in a switch-like manner in entering S-phase.

", " Furthermore, the pathway has been shown to encode the strength of signaling inputs though frequency modulated pulses of its activity. ", " Using live cell FRET biosensors, cells induced with different concentrations of EGF illicit activity bursts of different frequency, where higher levels of EGF resulted in more frequent bursts of ERK activity. ", "Furthermore, the dynamics of ERK activation in response to mitogens were found to be relevant for unique downstream responses including timing of S-phase entry in MCF10A cells. ", " Various types of growth factors can also lead to unique ERK dynamics in other cell types effecting cell fate, suggesting the temporal dynamics of ERK activation is a general means of encoding unique gene expression programs by cells.", "\n\nIntegration of mitogen and stress signals in proliferation\n\nRecent live cell imaging experiments in MCF10A and MCF7 cells have shown that a combination of mitogen signaling though ERK and stress signals through activation of p53 in mother cells contributes to the likelihood of whether newly formed daughter cells will immediately re-enter the cell cycle or enter quiescence (G0) preceding mitosis. ", "Rather than daughter cells starting with no key signaling proteins after division, mitogen/ERK induced Cyclin D1 mRNA and DNA damage induced p53 protein, both long lived factors in cells, can be stably inherited from mother cells after cell division. ", "The levels of these regulators vary from cell to cell after mitosis and stoichiometry between them strongly influences cell cycle commitment though activation of Cdk2. ", "Chemical perturbations using inhibitors of ERK signaling or inducers p53 signaling in mother cells suggest daughter cells with high levels of p53 protein and low levels of Cyclin D1 transcripts were shown to primarily enter G0 whereas cells with high Cyclin D1 and low levels of p53 are most likely to reenter the cell cycle.

", "In 1452 he was appointed chaplain to the nuns at the Monastery of St. Mary Magdalene in Florence, and in 1457 commendatoryRector (Rettore commendatario) of S. Quirico in Legania, from which institutions he occasionally made considerable profits; but his poverty seems to have been chronic, his money being spent, according to one account, in frequent amours.[citation needed]\n\nVasari relates Lippi's visits to Ancona and Naples, his capture by Barbary pirates and enslavement in Barbary, where his skill in portrait-sketching helped to release him.[3] From 1431 to 1437 his career is not accounted for.", "\n\nIn June 1456 Fra Filippo is recorded as living in Prato (near Florence) to paint frescoes in the choir of the cathedral.

Margherita in that city, where he met Lucrezia Buti, the beautiful daughter of a Florentine named Francesco Buti; she was either a novice of the Order or a young lady placed under the nuns' guardianship. ", "Lippi asked that she might be permitted to sit for the figure of the Madonna (or perhaps S. Margherita). ", "Under that pretext, Lippi engaged in sexual relations with her, abducted her to his own house, and kept her there despite the nuns' efforts to reclaim her. ", "The result was their son Filippino Lippi, who became a painter no less famous than his father. ", "Such is Vasari's narrative, published less than a century after the alleged events.", "\n\nThe frescoes in the choir of the cathedral of Prato, which depict the stories of St. John the Baptist and St. Stephen on the two main facing walls, are considered Fra Filippo's most important and monumental works, particularly the figure of Salome dancing, which has clear affinities with later works by Sandro Botticelli, his pupil, and Filippino Lippi, his son, as well as the scene showing the ceremonial mourning over Stephen's corpse. ", "This latter is believed to contain a portrait of the painter, but there are various opinions as to which is the exact figure. ", "On the end wall of the choir are S. Giovanni Gualberto and S. Alberto, while the vault has monumental representations of the four evangelists.", "\n\nThe close of Lippi's life was spent at Spoleto, where he had been commissioned to paint, for the apse of the cathedral, scenes from the life of the Virgin. ", "In the semidome of the apse is the Christ Crowning the Madonna, with angels, sibyls and prophets. ", "This series, which is not wholly equal to the one at Prato, was completed by one of his assistants, his fellow Carmelite, Fra Diamante, after Lippi's death. ", "That Lippi died in Spoleto, on or about the 8th of October 1469, is a fact; the mode of his death is a matter of dispute. ", "It has been said that the pope granted Lippi a dispensation for marrying Lucrezia, but before the permission arrived, Lippi had been poisoned by the indignant relatives of either Lucrezia herself or some lady who had replaced her in the inconstant painter's affections.[citation needed]\n\nThe altarpiece Lippi painted in 1441 for the nuns of S. Ambrogio is now a prominent attraction in the Academy of Florence, and was celebrated in Browning's well-known poem Fra Lippo Lippi. ", "It represents the coronation of the Virgin among angels and saints, including many Bernardine monks. ", "One of these, placed to the right, is a half-length portrait of Lippo, pointed out by the inscription perfecit opus upon an angel's scroll. ", "The price paid for this work in 1447 was 1200 Florentine lire, which seems surprisingly large.", "\n\nFor Germiniano Inghirami of Prato he painted the Death of St. Bernard.

Domenico — the Infant on the ground adored by the Virgin and Joseph, between Saints George and Dominic, in a rocky landscape, with the shepherds playing and six angels in the sky. ", "In the Uffizi is a fine Virgin adoring the infant Christ, who is held by two angels; in the National Gallery, London, a Vision of St Bernard. ", "The picture of the Virgin and Infant with an Angel, in this same gallery, also ascribed to Lippi, is disputable.", "\n\nFilippo Lippi died in 1469 while working on the frescoes of Scenes of the Life of the Virgin Mary, 1467–1469 in the apse of the Spoleto Cathedral. ", "The Frescos show the Annunciation, the Funeral, the Adoration of the Child and the Coronation of the Virgin. ", "A group of bystanders depicted at the funeral includes a self-portrait of Lippi, together with his son Filippino and his helpers, Fra Diamante and Pier Matteo d'Amelia.

STEELE, Chief Justice.", "\nThis 7th day of August 2007, upon consideration of the appellant's brief filed pursuant to Supreme Court Rule 26(c), his attorney's motion to withdraw, and the State's response thereto, it appears to the Court that:\n(1) The defendant-appellant, Patrick Henry, pleaded guilty in January 2006 to Possession With Intent to Deliver Ecstasy. ", "In September 2006, while serving the probationary portion of his sentence, Henry was arrested and charged with Trafficking in Cocaine, Possession With Intent to Deliver Cocaine and other crimes. ", "As a result, Henry was found to have committed a violation of probation (\"VOP\").", "\n(2) A contested VOP hearing was held on January 11, 2007. ", "The record reflects that, prior to the hearing, Henry, with his counsel, watched a DVD of his interview with police. ", "Henry's probation officer, two Delaware State Police officers, and Henry testified. ", "Detective Francis Fuscellaro, a member of the Governor's Task Force, testified to receiving a tip in September 2006 that Henry would be making a drug delivery to a mobile home park in Georgetown, Delaware. ", "Intercepting Henry before he made the delivery, the police found in his hand a Newport cigarette pack containing two baggies of a substance that later was confirmed to be crack cocaine, plus $583.00 in his pocket.", "\n(3) Henry testified that he did not know what was in the cigarette pack, and was only serving as a messenger. ", "He testified that he was high on cocaine at the time. ", "Henry also insisted that the police and probation officers on the Governor's Task Force had promised him that, if he told them who gave him the cocaine, he would receive only 60 days on the VOP and the new charges would be dropped. ", "He stated that the DVD corroborated his story. ", "Detective Fuscellaro denied that such a promise was made, stating that he had only agreed to tell the Attorney General's Office that Henry had been cooperative following his arrest.", "\n(4) After finding Henry in violation of his probation, the Superior Court judge heard testimony concerning Henry's subsequent arrest on drug charges in October 2006. ", "The judge ruled that the testimony was relevant only on the issue of Henry's sentence. ", "Again, Detective Fuscellaro testified that he received a tip that Henry would be making a delivery of crack cocaine and that the police intercepted Henry with the drugs before the transaction took place. ", "At a separate hearing, the judge sentenced Henry to 8 years of Level V incarceration, to be followed after 4 years and completion of the Key or Greentree Program by the Level IV Residential Substance Abuse Program, in turn to be followed by Level III Aftercare.[1] This is Henry's direct appeal from the VOP proceedings.", "\n(5) Henry's counsel has filed a brief and a motion to withdraw pursuant to Rule 26(c). ", "The standard and scope of review applicable to the consideration of a motion to withdraw and an accompanying brief under Rule 26(c) is twofold: (a) the Court must be satisfied that defense counsel has made a conscientious examination of the record and the law for claims that arguably could support the appeal; and (b) the Court must conduct its own review of the record and determine whether the appeal is so totally devoid of at least arguably appealable issues that it can be decided without an adversary presentation.[2]\n(6) Henry's counsel asserts that, based upon a careful and complete examination of the record, there are no arguably appealable issues. ", "By letter, Henry's counsel informed Henry of the provisions of Rule 26(c) and provided him with a copy of the motion to withdraw, the accompanying brief and the complete transcript. ", "Henry also was informed of his right to supplement his attorney's presentation. ", "Henry responded with a brief that raises several issues for this Court's consideration. ", "The State has responded to the position taken by Henry's counsel as well as the issues raised by Henry and has moved to affirm the Superior Court's judgment.", "\n(7) Henry raises several issues for this Court's consideration, which may fairly be summarized as follows: a) the police and probation officers reneged on their promise of leniency; b) his attorney provided ineffective assistance; c) the promise of leniency was recorded on a DVD, which is now missing; d) the Superior Court judge who presided over the VOP hearing should have recused himself; e) there was insufficient evidence presented at the hearing to support a finding of a VOP; and f) the judge's correction of his sentence in May 2007 violated principles of double jeopardy.", "\n(8) Henry's first claim is that the police and probation officers reneged on their promise of leniency. ", "The record reflects that Detective Fuscellaro's testimony directly contradicted Henry's testimony with respect to a promise of leniency. ", "The Superior Court judge, as the trier of fact, was the sole judge of the credibility of the witnesses and was responsible for resolving any conflicts in the testimony.[3] The Superior Court was, thus, within its discretion to credit the testimony of Detective Fuscallero over the testimony of Henry on this point. ", "We conclude, therefore, that this claim is without merit.", "\n(9) Henry's second claim is that his attorney provided ineffective assistance. ", "This claim was not raised below. ", "Because we will not entertain a claim of ineffective assistance raised for the first time on direct appeal, we decline to decide this claim at this time.[4]\n(10) Henry's third claim is that the promise of leniency was made during his interview with police and that the DVD of the interview is now missing. ", "The record does not reflect that the DVD is missing. ", "The hearing transcript reflects that, prior to the hearing, Henry watched the DVD with his counsel present. ", "At the hearing, Detective Fuscallero testified that he was not aware of any such discussion with Henry and that, if there had been, it would be on the DVD. ", "Henry's counsel did not cross-examine Detective Fuscallero about what was on the DVD, nor did she question Henry on that subject during his direct examination. ", "The clear implication is that the DVD did not corroborate Henry's testimony.", "\n(11) On cross-examination, Henry stated that the DVD would corroborate his memory of the deal he struck with the police. ", "However, Henry also admitted that he was high on cocaine at the time the police interviewed him. ", "The transcript of the hearing reflects that the Superior Court did not credit Henry's testimony concerning the alleged deal. ", "We find no abuse of discretion on the part of the Superior Court in so determining and, therefore, conclude that this claim is without merit.", "\n(12) Henry's fourth claim is that the Superior Court judge who presided over the VOP hearing should have recused himself, presumably because his familiarity with Henry would result in judicial bias. ", "Generally, a claim of bias on the part of a judge must stem from an extrajudicial source.[5] Because there is no evidence, indeed no claim, of any extrajudicial source of judicial bias, we conclude that Henry's fourth claim, too, is without merit.", "\n(13) Henry's fifth claim is that there was insufficient evidence presented at the hearing to support the finding of a VOP. ", "Because probation is an \"act of grace,\" the State need only present \"some competent evidence\" that the violation took place.[6] The eyewitness testimony of Detective Fuscellaro that he received a tip that Henry would be delivering drugs, and that he intercepted Henry and found crack cocaine packaged for sale in his hand constituted such \"competent evidence.\" ", "As such, we conclude that Henry's fifth claim is without merit.", "\n(14) Henry's sixth, and final, claim is that the Superior Court's May 16, 2007 order correcting his sentence violated principles of double jeopardy. ", "The double jeopardy clauses of the United States and Delaware Constitutions protect a criminal defendant against multiple punishments or successive prosecutions for the same offense.[7] Principles of double jeopardy are irrelevant to the circumstances presented here. ", "For that reason, we conclude that Henry's sixth claim is also without merit.", "\n(15) This Court has reviewed the record carefully and has concluded that Henry's appeal is wholly without merit and devoid of any arguably appealable issue. ", "We also are satisfied that Henry's counsel has made a conscientious effort to examine the record and has properly determined that Henry could not raise a meritorious claim in this appeal.", "\nNOW, THEREFORE, IT IS ORDERED that the State's motion to affirm is GRANTED.
