description: The relativistic generalization of the theory of superconductivity is reviewed with respect to its conceptual basis and first applications. The construction of relativistically covariant order parameters for superconductors is outlined and the generalization of the Dirac equation for the superconducting state is presented. A weakly relativistic expansion of this equation leads to the Pauli equation for superconductors, which describes the lowest-order relativistic corrections to the conventional theory of superconductivity. The physics of these corrections is discussed, and the prospects for experimental detection of relativistic effects in superconductors are examined.

description: Hydrogen detection is of great importance in chemical and energy industries. Optical fiber hydrogen sensors show flexibility and compactness and have the potential for distributed analysis. However, traditional fiber sensors encounter a challenge for light to interact with hydrogen directly since hydrogen only display weak quadrupole absorption, and metallic palladium and platinum thin-film coatings are typically used as an optically detectable label. Here, based on stimulated Raman spectroscopy in hollow-core photonic crystal fibers, we investigate the label-free optical fiber distributed hydrogen sensors operating in the optical telecommunication band. The approach of distributed Raman measurement represents a new paradigm in fiber sensors, potentially allowing distributed chemical analysis in gas or liquid phase with high sensitivity and selectivity.

Coulomb drag at ν= 1/2: Composite fermion pairing fluctuations

description: We consider the Coulomb drag between two two-dimensional electron layers at filling factor ν= 1/2 each, using a strong coupling approach within the composite fermion picture. Due to an attractive interlayer interaction, composite fermions are expected to form a paired state below a critical temperature T_c. We find that above T_c pairing fluctuations make the longitudinal transresistivity ρ_D increase with decreasing temperature. The pairing mechanism we study is very sensitive to density variations in the two layers, and to an applied current. We discuss possible relation to an experiment by Lilly et al. [Phys. Rev. Lett. 80, 1714 (1998)].

description: In theories with gauge mediated supersymmetry breaking, the scalar tau, (${\tilde τ_1}$) is the lightest superpartner for a large range of the parameter space. At the large electron positron collider (LEP 2) this scenario can give rise to events with four $τ$ leptons and large missing energy. Two of the $τ$'s ( coming from the decays of ${\tilde τ_1}$'s ) will have large energy and transverse momentum, and can have similar sign electrical charges. Such events are very different from the usual photonic events that have been widely studied, and could be a very distinct signal for the discovery of supersymmetry.

description: We study the Langevin dynamics of the standard random heteropolymer model by mapping the problem to a supersymmetric field theory using the Martin-Siggia-Rose formalism. The resulting model is solved non-perturbatively employing a Gaussian variational approach. In constructing the solution, we assume that the chain is very long and impose the translational invariance which is expected to be present in the bulk of the globule by averaging over the center the of mass coordinate. In this way we derive equations of motion for the correlation and response functions C(t,t') and R(t,t'). The order parameters are extracted from the asymptotic behavior of these functions. We find a dynamical phase diagram with frozen (glassy) and melted (ergodic) phases. In the glassy phase the system fails to reach equilibrium and exhibits aging of the type found in p-spin glasses. Within the approximations used in this study, the random heteropolymer model can be mapped to the problem of a manifold in a random potential with power law correlations.

description: Two concentric dual-coaxial SIR filters with different structures are proposed. The first is that the upper resonant cap wraps the lower resonant cap; the second is that the cap of the upper resonator no longer wraps the lower resonator. The dual-coaxial quarter-wavelength SIR structure improves the anti-vibration capability of the resonator, and the structure makes full use of the resonator space and improves the unloaded Q value. The insertion loss of the first filter is less than 0.3 dB, and the insertion loss of the second filter is less than 1.5 dB.

description: New entropy stable spectral collocations schemes of arbitrary order of accuracy are developed for the unsteady 3-D Euler and Navier-Stokes equations on dynamic unstructured grids. To take into account the grid motion and deformation, we use an arbitrary Lagrangian-Eulerian (ALE) formulation. As a result, moving and deforming hexahedral grid elements are individually mapped onto a cube in the fixed reference system of coordinates. The proposed scheme is constructed by using the skew-symmetric form of the Navier-Stokes equations, which are discretized by using summation-by-parts spectral collocation operators that preserve the conservation properties of the original governing equations. Furthermore, the metric coefficients are approximated such that the geometric conservation laws (GCL) are satisfied exactly on both static and dynamic grids. To make the scheme entropy stable, a new entropy conservative flux is derived for the 3-D Euler and Navier-Stokes equations on dynamic unstructured grids. The new flux preserves the design order of accuracy of the original spectral collocation scheme and guarantees the entropy conservation on moving and deforming grids. We present numerical results demonstrating design order of accuracy and freestream preservation properties of the new schemes for both the Euler and Navier-Stokes equations on moving and deforming unstructured grids.

description: A critical value in the product of the anisotropy parameter and the magnetic field is observed in interlayer Josephson-vortex systems by extensive Monte Carlo simulations. Below/above this critical value the thermodynamic phase transition between the normal and the superconducting states upon temperature sweeping is first/second order. The origin is the intrinsic pinning effect of the layered structure of high-Tc superconductors.

description: Gender-based violence has long been a widely researched social issue in multiple contexts, and media framing of gender issues is important for public understanding and responsiveness. Considering gender-based violence is rife in contemporary China, this study is dedicated to exploring the discourses of official media’s representation of gender-based violence in China and exposing the social mechanism behind it. Drawing on critical discourse analysis, this study collected data from representative Chinese official media and conducted qualitative and quantitative analyses. Research findings indicate that 1) muted misogyny is predominant when official media reports violence against women since discussions of controversial issues are under censorship; 2) a de-gendering discourse has been adopted to distract the public’s attention from debates of gender-based violence; and 3) structural violence framing may explain the social mechanism of how media present and represent the gender-based violence issues in a non-Western context. These findings shed light on the ongoing theoretical debates of media representation of gender issues and contribute to our understanding of how discourses of official media could work positively to improve women’s situation.

description: To update the clinical practice guidelines for nutrition therapy of the European Association for the Study of Diabetes, we conducted a systematic review and meta-analysis of prospective cohort studies and randomized clinical trials (RCTs) to evaluate the effect of the Mediterranean diet (MedDiet) on the prevention of cardiovascular disease (CVD) incidence and mortality. We searched Medline, EMBASE (through April 20, 2018) and Cochrane (through May 7, 2018) databases. Pooled relative risks (RRs) and 95% confidence interval (CI) were calculated by the generic inverse variance method. A total of 41 reports (3 RCTs and 38 cohorts) were included. Meta-analyses of RCTs revealed a beneficial effect of the MedDiet on total CVD incidence (RR: 0.62; 95% CI: 0.50, 0.78) and total myocardial infarction (MI) incidence (RR: 0.65; 95% CI: 0.49, 0.88). Meta-analyses of prospective cohort studies, which compared the highest versus lowest categories of MedDiet adherence, revealed an inverse association with total CVD mortality (RR: 0.79; 95% CI: 0.77, 0.82), coronary heart disease (CHD) incidence (RR: 0.73; 95% CI: 0.62, 0.86), CHD mortality (RR: 0.83; 95% CI: 0.75, 0.92), stroke incidence (RR: 0.80; 95% CI: 0.71, 0.90), stroke mortality (RR: 0.87; 95% CI: 0.80, 0.96) and MI incidence (RR: 0.73; 95% CI: 0.61, 0.88). The present study suggests that MedDiet has a beneficial role on CVD prevention in populations inclusive of individuals with diabetes.

description: The metastable orthorhombic phase of hafnia is generally obtained in polycrystalline films, whereas in epitaxial films, its formation has been much less investigated. We have grown Hf0.5Zr0.5O2 films by pulsed laser deposition, and the growth window (temperature and oxygen pressure during deposition and film thickness) for epitaxial stabilization of the ferroelectric phase is mapped. The remnant ferroelectric polarization, up to around 24 uC/cm2, depends on the amount of orthorhombic phase and interplanar spacing and increases with temperature and pressure for a fixed film thickness. The leakage current decreases with an increase in thickness or temperature, or when decreasing oxygen pressure. The coercive electric field (EC) depends on thickness (t) according to the coercive electric field (Ec) - thickness (t)-2/3 scaling, which is observed for the first time in ferroelectric hafnia, and the scaling extends to thicknesses down to around 5 nm. The proven ability to tailor the functional properties of high-quality epitaxial ferroelectric Hf0.5Zr0.5O2 films paves the way toward understanding their ferroelectric properties and prototyping devices.

description: We analyse in detail the supersymmetric contributions to the decay of an extra Z boson in effective rank 5 models, including the important effect of D-terms on sfermion masses. The inclusion of supersymmetric decay channels will reduce the Z' branching ratio to standard model particles resulting in lower Z' mass limits than those often quoted. In particular, the supersymmetric parameter space motivated by the recent Fermilab $eeγγ$ event and other suggestive evidence results in a branching fraction B(Z' -> e^+ e^-)\simeq 2-4%. The expected cross sections and branching ratios could give a few events in the present data and we speculate on the connection to the three e^+e^- events observed at Fermilab with large dielectron invariant mass.

description: The metallicity and its relationship with other galactic properties is a fundamental probe of the evolution of galaxies. In this work, we select about 750,000 star-forming spatial pixels from 1122 blue galaxies in the MaNGA survey to investigate the global stellar mass - local stellar mass surface density - gas-phase metallicity ($M_*$ - $Σ_*$ - $Z$ ) relation. At a fixed $M_*$, the metallicity increases steeply with increasing $Σ_*$. Similarly, at a fixed $Σ_*$, the metallicity increases strongly with increasing $M_*$ at low mass end, while this trend becomes less obvious at high mass end. We find the metallicity to be more strongly correlated to $Σ_*$ than to $M_*$. Furthermore, we construct a tight (0.07 dex scatter) $M_*$ - $Σ_*$ - $Z$ relation, which reduces the scatter in the $Σ_*$ - $Z$ relation by about 30$\%$ for galaxies with $7.8 < {\rm log}(M_*/M_\odot) < 11.0$, while the reduction of scatter is much weaker for high-mass galaxies. This result suggests that, especially for low-mass galaxies, the $M_*$ - $Σ_*$ - $Z$ relation is largely more fundamental than the $M_*$ - $Z$ and $Σ_*$ - $Z$ relations, meaning that both $M_*$ and $Σ_*$ play important roles in shaping the local metallicity. We also find that the local metallicity is probably independent on the local star formation rate surface density at a fixed $M_*$ and $Σ_*$. Our results are consistent with the scenario that the local metallicities in galaxies are shaped by the combination of the local stars formed in the history and the metal loss caused by galactic winds.

description: We examine sedimentation density profiles of star polymer solutions as an example of colloidal systems in sedimentation equilibrium which exhibit reentrant melting in their bulk phase diagram. Phase transitions between a fluid and a fluid with an intercalated solid are observed below a critical gravitational strength $α^{*}$. Characteristics of the two fluid-solid interfaces in the density profiles occurring in Monte Carlo simulations for $α< α^{*}$ are in agreement with scaling laws put forth in the framework of a phenomenological theory. Furthermore we detect density oscillations at the fluid-gas interface at high altitudes for high gravitational fields, which are verified with density functional theory and should be observable in surface scattering experiments.

description: Simplified GAN Model. Same legend as Fig. 2. The simplified version of GAN model is when a A-cell only performs A→(N,N) divisions, so γA(t) is forced to the value 1 at any time. This simplified version yields predictions which are practically identical to GAN predictions, except a slight difference in the early rise of nn-divisions, and an incorrect prediction for the MoD under the GoF of mutated CDC25B experiment (i).

description: The thermal conductivity of polycrystalline samples of (Na,Ca)Co_2O_4 is found to be unusually low, 20 mW/cmK at 280 K. On the assumption of the Wiedemann-Franz law, the lattice thermal conductivity is estimated to be 18 mW/cmK at 280 K, and it does not change appreciably with the substitution of Ca for Na. A quantitative analysis has revealed that the phonon mean free path is comparable with the lattice parameters, where the point-defect scattering plays an important role. Electronically the same samples show a metallic conduction down to 4.2 K, which strongly suggests that NaCo_2O_4 exhibits a glass-like poor thermal conduction together with a metal-like good electrical conduction. The present study further suggests that a strongly correlated system with layered structure can act as a material of a phonon glass and an electron crystal.

description: We present a polynomial complexity, deterministic, heuristic for solving the Hamiltonian Cycle Problem (HCP) in an undirected graph of order $n$. Although finding a Hamiltonian cycle is not theoretically guaranteed, we have observed that the heuristic is successful even in cases where such cycles are extremely rare, and it also performs very well on all HCP instances of large graphs listed on the TSPLIB web page. The heuristic owes its name to a visualisation of its iterations. All vertices of the graph are placed on a given circle in some order. The graph's edges are classified as either snakes or ladders, with snakes forming arcs of the circle and ladders forming its chords. The heuristic strives to place exactly $n$ snakes on the circle, thereby forming a Hamiltonian cycle. The Snakes and Ladders Heuristic (SLH) uses transformations inspired by $k-$opt algorithms such as the, now classical, Lin-Kernighan heuristic to reorder the vertices on the circle in order to transform some ladders into snakes and vice versa. The use of a suitable stopping criterion ensures the heuristic terminates in polynomial time if no improvement is made in $n^3$ major iterations.

description: We investigate how human decision-makers handle the two-class capacity allocation problem—a foundational revenue management problem and a cornerstone for more sophisticated scenarios. We consider the problem with ordered and unordered arrivals, and then introduce a simplified version with single up-front decision. We explore the decisions across two price ratios, symbolizing heterogeneous vs. more homogeneous customer bases. We find that decision-makers ineffectively allocate capacity, resulting in suboptimal revenues and underutilization of RM potential. Theoretically, the decision-making format for the capacity does not matter, whereas we find that decision-makers set higher protection levels when making an up-front decision rather than sequential decisions and earn higher revenues for heterogeneous customers. Decision-makers perform poorly in sequential decision-making, and heuristics can be useful in improving performance. Moreover, we observe several regularities in decision-making. With higher customer heterogeneity, decision-makers tend to accept customers who would have been declined by the optimal policy, indicating they are less demanding. Conversely, with more homogeneous customers, they tend to turn away customers who would have been accepted by the optimal policy, implying they are more demanding. Lastly, we investigate whether the decision-making is affected by feelings of regret and find strong effects for both winner’s and loser’s experienced regret.

description: The effect of a weak random potential on two-leg Hubbard ladders is investigated. The random potential is shown to induce Anderson localization except for attractive enough interactions, supressing completely d-wave superconductivity. These localization effects remain very strong even for many ladders coupled by Josephson coupling. Both dc and ac conductivities and localization lengths are obtained. Consequences for the superconducting ladder compound Sr$_x$Ca$_{14-x}$Cu$_{24}$O$_{41+δ}$ are discussed.

description: Transform of essential information through cloud computing require security analysis. Different data or images are transformed or access through could computing is challenging since it suffer from different type of risk. There are different types of information’s such as image, data, audio, video etc are transformed through the cloud computing. To protect such essential information from different types of treat requires a well method that protects information. For this reason, the encryption method is used to guard such vital information. This paper analysis and survey different image encryption technique and different from of security analysis. There are different types of security analysis such as NPCR, UACI, entropy etc that make encryption method strongest and protect essential information from different types of attacks.

description: Information assets that complement each other capture the information security characteristics of supply chain firms. Supply chain firms usually outsource security services to Managed Security Service Providers (MSSPs) to protect their information. Considering the security externality and information leakage risk in security outsourcing, this article investigates four security management scenarios faced by two supply chain firms. We try to answer whether both firms should outsource security to the same or different MSSPs. We find that no matter under which scenario, as the complementation degree increases, both firms and MSSPs decrease the security quality, and MSSPs offer a contract with lower compensation. We show that information leakage risk and security externality have different effects on the MSSP’s optimal strategy selections. Besides, the MSSP tends to serve both firms when the security externality is positive but prefers serving only one firm when the security externality is negative. Moreover, we find that the strategy that one firm outsources to an MSSP and its partner manages it in-house can be the optimal selection for the social planner but not the MSSP’s optimal strategy. We also extend the model and find that the results are robust to the situations of uncertain loss and asymmetric loss.

description: We observe enhanced second-harmonic generation in monolayer graphene in the presence of an ultra-strong terahertz field pulse with a peak amplitude of 250 kV/cm. This is a strongly nonperturbative regime of light-matter interaction in which particles get accelerated to energies exceeding the initial Fermi energy of 0.2 eV over a timescale of a few femtoseconds. The second-harmonic current is generated as electrons drift through the region of momenta corresponding to interband transition resonance at an optical frequency. The resulting strongly asymmetric distortion of carrier distribution in momentum space gives rise to an enhanced electric-dipole nonlinear response at the second harmonic. We develop an approximate analytic theory of this effect which accurately predicts observed intensity and polarization of the second-harmonic signal.

description: We study correspondence between a phase oscillator network with distributed natural frequencies and a classical XY model at finite temperatures with the same random and frustrated interactions used in the Sherrington-Kirkpatrick model. We perform numerical calculations of the spin glass order parameter $q$ and the distributions of the local fields. As a result, we find that the parameter dependences of these quantities in both models agree fairly well if parameters are normalized by using the previously obtained correspondence relation between two models with the same other types of interactions. Furthermore, we numerically calculate several quantities such as the time evolution of the instantaneous local field in the phase oscillator network in order to study the roles of synchronous and asynchronous oscillators. We also study the self-consistent equation of the local fields in the oscillator network and XY model derived by the mean field approximation.

description: El abordaje específico de la salud mental se ha desarrollado desde la segunda mitad de siglo XX y las intervenciones planteadas por el Estado Colombiano han sido cuestionadas en términos de su pertinencia y alcance. Esta investigación plantea una aproximación, desde la noción de Campo y la perspectiva de Pierre Bourdieu, a la relación entre los problemas y trastornos mentales y el desarrollo del Capital global (Capital social, cultural, simbólico y económico) de las personas afectadas. Se establece (1) un análisis crítico del abordaje sociológico en salud mental, acogiendo la perspectiva bourdiana en tanto amplia, comprensiva y novedosa, (2) se realiza una aproximación a los diferentes capitales y su correlación con problemas y trastornos que afectan a los colombianos de acuerdo con la Encuesta Nacional de Salud Mental de 2015 y por último (3) se analiza el desarrollo normativo en salud mental, y su correspondencia con el abordaje adecuado de las afectaciones y sus correlatos. Finalmente, se discuten las limitaciones normativas como un producto de la tensión entre el reconocimiento del derecho a la salud (y a la salud mental) y el énfasis gubernamental en el capital económico que afecta la eficacia y legitimidad de la norma y del Estado Colombiano
description: The specific approach to mental health has been developed since the second half of the 20th century and the interventions proposed by the Colombian State have been questioned in terms of their relevance and scope. This research proposes an approach, from the notion of Field and the perspective of Pierre Bourdieu, to the relationship between mental problems and disorders and the development of global Capital (social, cultural, symbolic and economic capital) of the affected people. This doctoral thesis make (1) A critical analysis of the sociological approach to mental health, accepting the Bourdieu´s perspective as broad, comprehensive and novel, (2) an approach is made to the different capitals and their correlation with problems and disorders that affect Colombians according to the National Mental Health Survey (2015) and (3) the normative development in mental health is analyzed, and its correspondence with the adequate approach to the affectations and their correlates. Finally, normative limitations are discussed as a product of the tension between the recognition of the right to health (and mental health) and the government's emphasis on economic capital that affects the efficacy and legitimacy of the norm and the Colombian State.
Soliton-limited Superflow in 3He-A between Parallel Plates

description: We have studied theoretically the flow of superfluid 3He-A in parallel-plate geometry. The equilibrium order-parameter texture is calculated numerically in two spatial dimensions consisting of the coordinates along the flow direction and perpendicular to the plates. The calculations have been done using the hydrostatic theory in the Ginzburg-Landau region and assuming a large external magnetic field perpendicular to the plane of calculation. We have studied a uniform texture and a dipole-unlocked splay soliton as initial configurations. In the former case we find the Freedericksz transition and a helical instability with increasing flow. In the latter case we find instability in the soliton. This instability is closely related to the critical velocity in the presence of a vortex sheet. Also, the transverse NMR frequency shift at the soliton has been calculated.

description: We introduce a mesoscopic model for the formation and evolution of shear bands in loose granular media. Numerical simulations reveal that the system undergoes a non-trivial self-organization process which is governed by the motion of the shear band and the consequent restructuring of the material along it. High density regions are built up, progressively confining the shear bands in localized regions. This results in an inhomogeneous aging of the material with a very slow increase in the mean density, displaying an unusual glassy like system-size dependence.
