description: We examine data from the DAMA, CoGeNT, CRESST-II and CDMS/Si direct detection experiments in the context of multi-component hidden sector dark matter. The models considered feature a hidden sector with two or more stable particles charged under an unbroken $U(1)'$ gauge interaction. The new gauge field can interact with the standard $U(1)_Y$ via renormalizable kinetic mixing, leading to Rutherford-type elastic scattering of the dark matter particles off ordinary nuclei. We consider the simplest generic model of this type, with a hidden sector composed of two stable particles, $F_1$ and $F_2$. We find that this simple model can simultaneously explain the DAMA, CoGeNT, CRESST-II and CDMS/Si data. This explanation has some tension with the most recent results from the XENON100 experiment.

description: We consider a theory for a two-dimensional interacting conduction electron system with strong spin-orbit coupling on the interface between a topological insulator and the magnetic (ferromagnetic or antiferromagnetic) layer. For the ferromagnetic case we derive the Landau-Lifshitz equation, which features a contribution proportional to a fluctuation-induced electric field obtained by computing the topological (Chern-Simons) contribution from the vacuum polarization. We also show that fermionic quantum fluctuations reduce the critical temperature $\tilde T_c$ at the interface relative to the critical temperature $T_c$ of the bulk, so that in the interval $\tilde T_c\leq T

асфиксия новорожденных

description: Гипоксически-ишемическая энцефалопатия (ГИЭ) новорожденных — это острое повреждение головного мозга, возникающее вследствие ограниченности поступления кислорода и питательных веществ в головной мозг из-за нарушения кровоснабжения во время внутриутробного, интранатального или послеродового периода. К 2 годам до 60 % детей с ГИЭ умирают или имеют серьезные нарушения, включая умственную отсталость, эпилепсию и церебральный паралич (ДЦП) [1]. В настоящее время единственным методом лечения младенцев с ГИЭ является терапевтическая гипотермия. Считается, что гипотермия эффективна, поскольку она снижает уровень свободных радикалов и глутамата, уменьшает потребность в кислороде и снижает апоптотическую гибель клеток [2]. Для эффективного лечения терапевтическую гипотермию необходимо проводить в течение первых 6 часов жизни. Однако, около 20 % новорожденных младенцев, у которых в итоге разовьется ГИЭ средней или тяжелой степени, остаются без должного клинического внимания [3]. Для ранней дифференциальной диагностики ГИЭ новорожденных могут быть применимы подходы, основанные на анализе метаболических изменений в крови новорожденных с использованием хромато-масс-спектрометрии. Использование дополнительных критериев, таких как метаболомные маркеры, будет способствовать более точной и своевременной постановке диагноза и дифференциальной диагностике сочетанных повреждений. Клинические исследования в неонатальный период очень ограничены, при исследовании динамики молекулярного состава биологических жидкостей преимуществом 97 обладают неинвазивные образцы (моча, стул), а также малоинвазивные образцы (кровь, сухое пятно крови).

description: We construct minimal electronic models for a newly discovered superconductor LaO$_{1-x}$F$_x$BiS$_2$ ($T_c=$ 10.6K) possessing BiS$_2$ layers based on first principles band calculation. First, we obtain a model consisting of two Bi $6p$ and two S $3p$ orbitals, which give nearly electron-hole symmetric bands. Further focusing on the bands that intersect the Fermi level, we obtain a model with two $p$ orbitals. The two bands (per BiS$_2$ layer) have quasi-one-dimensional character with a double minimum dispersion, which gives good nesting of the Fermi surface. At around $x\sim 0.5$ the topology of the Fermi surface changes, so that the density of states at the Fermi level becomes large. Possible pairing states are discussed.

description: Switchable metamaterials offer unique solutions for efficiently manipulating electromagnetic waves, particularly for terahertz waves, which has been difficult since naturally occurring materials rarely respond to terahertz frequencies controllably. However, few terahertz modulators demonstrated to date exhibit simultaneously low attenuation and high modulation depth. In this letter we propose a new class of electrically-tunable terahertz metamaterial modulators employing metallic frequency-selective-surfaces (FSS) in conjunction with capacitively-tunable layers of electrons, promising near 100% modulation depth and < 15% attenuation. The fundamental departure in our design from the prior art is tuning enabled by self-gated electron layers that is independent from the metallic FSS. Our proposal is applicable to all possible electrically tunable elements including graphene, Si, MoS2, oxides etc, thus opening up myriad opportunities for realizing high performance switchable metamaterials over an ultra-wide terahertz frequency range.

description: We study the design of amplitude phase-shift keying (APSK) constellations for a coherent fiber-optical communication system where nonlinear phase noise (NLPN) is the main system impairment. APSK constellations can be regarded as a union of phase-shift keying (PSK) signal sets with different amplitude levels. A practical two-stage (TS) detection scheme is analyzed, which performs close to optimal detection for high enough input power. We optimize APSK constellations with 4, 8, and 16 points in terms of symbol error probability (SEP) under TS detection for several combinations of input power and fiber length. Our results show that APSK is a promising modulation format in order to cope with NLPN. As an example, for 16 points, performance gains of 3.2 dB can be achieved at a SEP of 10^-2 compared to 16-QAM by choosing an optimized APSK constellation. We also demonstrate that in the presence of severe nonlinear distortions, it may become beneficial to sacrifice a constellation point or an entire constellation ring to reduce the average SEP. Finally, we discuss the problem of selecting a good binary labeling for the found constellations. For the class of rectangular APSK a labeling design method is proposed, resulting in near-optimal bit error probability.

description: The growth of supermassive black holes appears to be driven by galaxy mergers, violent merger-free processes and/or `secular' processes. In order to quantify the effects of secular evolution on black hole growth, we study a sample of active galactic nuclei (AGN) in galaxies with a calm formation history free of significant mergers, a population that heretofore has been difficult to locate. Here we present an initial sample of 13 AGN in massive (M_* >~ 1e10 M_sun) bulgeless galaxies -- which lack the classical bulges believed inevitably to result from mergers -- selected from the Sloan Digital Sky Survey using visual classifications from Galaxy Zoo. Parametric morphological fitting confirms the host galaxies lack classical bulges; any contributions from pseudobulges are very small (typically < 5%). We compute black hole masses for the two broad-line objects in the sample (4.2e6 and 1.2e7 M_sun) and place lower limits on black hole masses for the remaining sample (typically M_BH >~ 1e6 M_sun), showing that significant black hole growth must be possible in the absence of mergers or violent disk instabilities. The black hole masses are systematically higher than expected from established bulge-black hole relations. However, if the mean Eddington ratio of the systems with measured black hole masses (L/L_Edd = 0.065) is typical, 10 of 13 sources are consistent with the correlation between black hole mass and total stellar mass. That pure disk galaxies and their central black holes may be consistent with a relation derived from elliptical and bulge-dominated galaxies with very different formation histories implies the details of stellar galaxy evolution and dynamics may not be fundamental to the co-evolution of galaxies and black holes.

description: The paper provides a systematic characterization of quantum ergodic and mixing channels in finite dimensions and a discussion of their structural properties. In particular, we discuss ergodicity in the general case where the fixed point of the channel is not a full-rank (faithful) density matrix. Notably, we show that ergodicity is stable under randomizations, namely that every random mixture of an ergodic channel with a generic channel is still ergodic. In addition, we prove several conditions under which ergodicity can be promoted to the stronger property of mixing. Finally, exploiting a suitable correspondence between quantum channels and generators of quantum dynamical semigroups, we extend our results to the realm of continuous-time quantum evolutions, providing a characterization of ergodic Lindblad generators and showing that they are dense in the set of all possible generators.

description: We present the structural, magnetic, thermal and ab-plane electronic transport properties of single crystals of CaCu1.7As2 grown by the self-flux technique that were investigated by powder x-ray diffraction, magnetic susceptibility chi, isothermal magnetization M, specific heat Cp, and electrical resistivity rho measurements as a function of temperature T and magnetic field H. X-ray diffraction analysis of crushed crystals at room temperature confirm the collapsed tetragonal ThCr2Si2-type structure with \sim 15% vacancies on the Cu sites as previously reported, corresponding to the composition CaCu1.7As2. The chi(T) data are diamagnetic, anisotropic and nearly independent of T. The chi is larger in the ab-plane than along the c-axis, as also observed previously for SrCu2As2 and for pure and doped BaFe2As2. The Cp(T) and rho(T) data indicate metallic sp-band character. In contrast to the chi(T) and Cp(T) data that do not show any evidence for phase transitions below 300 K, the rho(T) data exhibit a sharp increase in slope on cooling below a temperature Tt = 54-56 K, depending on the crystal. The ρ(T) data show no hysteresis on warming and cooling through Tt and the transition appears to be second order. The phase transition may arise from spatial ordering of the vacancies on the Cu sublattice. The Tt is found to be independent of H for H \leq 8 T. A positive magnetoresistance is observed below Tt that increases with decreasing T and attains a value in H = 8.0 T of 8.7% at T = 1.8 K.

description: This paper aims to go beyond resilience into the study of security and local-repairability for distributed storage systems (DSS). Security and local-repairability are both important as features of an efficient storage system, and this paper aims to understand the trade-offs between resilience, security, and local-repairability in these systems. In particular, this paper first investigates security in the presence of colluding eavesdroppers, where eavesdroppers are assumed to work together in decoding stored information. Second, the paper focuses on coding schemes that enable optimal local repairs. It further brings these two concepts together, to develop locally repairable coding schemes for DSS that are secure against eavesdroppers. The main results of this paper include: a. An improved bound on the secrecy capacity for minimum storage regenerating codes, b. secure coding schemes that achieve the bound for some special cases, c. a new bound on minimum distance for locally repairable codes, d. code construction for locally repairable codes that attain the minimum distance bound, and e. repair-bandwidth-efficient locally repairable codes with and without security constraints.

description: We show that if an inclusion of finite groups H < G of index prime to p induces a homeomorphism of mod p cohomology varieties, or equivalently an F-isomorphism in mod p cohomology, then H controls p-fusion in G, if p is odd. This generalizes classical results of Quillen who proved this when H is a Sylow p-subgroup, and furthermore implies a hitherto difficult result of Mislin about cohomology isomorphisms. For p=2 we give analogous results, at the cost of replacing mod p cohomology with higher chromatic cohomology theories. The results are consequences of a general algebraic theorem we prove, that says that isomorphisms between p-fusion systems over the same finite p-group are detected on elementary abelian p-groups if p odd and abelian 2-groups of exponent at most 4 if p=2.

SU(3) Spin-Orbit Coupling in Systems of Ultracold Atoms

description: Motivated by the recent experimental success in realizing synthetic spin-orbit coupling in ultracold atomic systems, we consider N-component atoms coupled to a non-Abelian SU(N) gauge field. More specifically, we focus on the case, referred to here as "SU(3) spin-orbit-coupling," where the internal states of three-component atoms are coupled to their momenta via a matrix structure that involves the Gell-Mann matrices (in contrast to the Pauli matrices in conventional SU(2) spin-orbit-coupled systems). It is shown that the SU(3) spin-orbit-coupling gives rise to qualitatively different phenomena and in particular we find that even a homogeneous SU(3) field on a simple square lattice enables a topologically non-trivial state to exist, while such SU(2) systems always have trivial topology. In deriving this result, we first establish an exact equivalence between the Hofstadter model with a 1/N Abelian flux per plaquette and a homogeneous SU(N) non-Abelian model. The former is known to have a topological spectrum for N>2, which is thus inherited by the latter. It is explicitly verified by an exact calculation for N=3, where we develop and use a new algebraic method to calculate topological indices in the SU(3) case. Finally, we consider a strip geometry and establish the existence of three gapless edge states -- the hallmark feature of such an SU(3) topological insulator.

Robustly invariant sets in fibre contracting bundle flows

Publisher: name: arXiv
Year: 2012
Subjects: subject: Dynamical Systems (math.DS)

description: We provide abstract conditions which imply the existence of a robustly invariant neighbourhood of a global section of a fibre bundle flow. We then apply such a result to the bundle flow generated by an Anosov flow when the fibre is the space of jets (which are described by local manifolds). As a consequence we obtain sets of manifolds (e.g. approximations of stable manifolds) that are left invariant, {\bf for all} negative times, by the flow and its small perturbations. Finally, we show that the latter result can be used to easily fix a mistake recently uncovered in the paper {\em Smooth Anosov flows: correlation spectra and stability}, \cite{BuL}, by the present authors.
description: This is a completely revised version of "Smooth Invariant Cone Fields: Errata Corrige to "Smooth Anosov Flows: Correlation Spectra and Stability"".

Rheological hysteresis in soft glassy materials

description: The nonlinear rheology of a soft glassy material is captured by its constitutive relation, shear stress vs shear rate, which is most generally obtained by sweeping up or down the shear rate over a finite temporal window. For a huge amount of complex fluids, the up and down sweeps do not superimpose and define a rheological hysteresis loop. By means of extensive rheometry coupled to time-resolved velocimetry, we unravel the local scenario involved in rheological hysteresis for various types of well-studied soft materials. We introduce two observables that quantify the hysteresis in macroscopic rheology and local velocimetry respectively, as a function of the sweep rate δt^{-1}. Strikingly, both observables present a robust maximum with δt, which defines a single material-dependent timescale that grows continuously from vanishingly small values in simple yield stress fluids to large values for strongly time-dependent materials. In line with recent theoretical arguments, these experimental results hint at a universal timescale-based framework for soft glassy materials, where inhomogeneous flows characterized by shear bands and/or pluglike flow play a central role.

Transitionless quantum driving for spin systems

Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We apply the method of transitionless quantum driving for time-dependent quantum systems to spin systems. For a given Hamiltonian, the driving Hamiltonian is constructed so that the adiabatic states of the original system obey the Schroedinger equation. For several typical systems such as the XY spin chain and the Lipkin-Meshkov-Glick model, the driving Hamiltonian is constructed explicitly. We discuss possible interesting situations when the driving Hamiltonian becomes time independent and when the driving Hamiltonian is equivalent to the original one. For many-body systems, a crucial problem occurs at the quantum phase transition point where the energy gap between the ground and first excited states becomes zero. We discuss how the defect can be circumvented in the present method.

description: We utilize genetic algorithms to find optimal dynamical decoupling (DD) sequences for a single-qubit system subjected to a general decoherence model under a variety of control pulse conditions. We focus on the case of sequences with equal pulse-intervals and perform the optimization with respect to pulse type and order. In this manner we obtain robust DD sequences, first in the limit of ideal pulses, then when including pulse imperfections such as finite pulse duration and qubit rotation (flip-angle) errors. Although our optimization is numerical, we identify a deterministic structure underlies the top-performing sequences. We use this structure to devise DD sequences which outperform previously designed concatenated DD (CDD) and quadratic DD (QDD) sequences in the presence of pulse errors. We explain our findings using time-dependent perturbation theory and provide a detailed scaling analysis of the optimal sequences.

description: We develop a perturbative approach to redshift space distortions (RSD) using the phase space distribution function approach and apply it to the dark matter redshift space power spectrum and its moments. RSD can be written as a sum over density weighted velocity moments correlators, with the lowest order being density, momentum density and stress energy density. We use standard and extended perturbation theory (PT) to determine their auto and cross correlators, comparing them to N-body simulations. We show which of the terms can be modeled well with the standard PT and which need additional terms that include higher order corrections which cannot be modeled in PT. Most of these additional terms are related to the small scale velocity dispersion effects, the so called finger of god (FoG) effects, which affect some, but not all, of the terms in this expansion, and which can be approximately modeled using a simple physically motivated ansatz such as the halo model. We point out that there are several velocity dispersions that enter into the detailed RSD analysis with very different amplitudes, which can be approximately predicted by the halo model. In contrast to previous models our approach systematically includes all of the terms at a given order in PT and provides a physical interpretation for the small scale dispersion values. We investigate RSD power spectrum as a function of μ, the cosine of the angle between the Fourier mode and line of sight, focusing on the lowest order powers of μand multipole moments which dominate the observable RSD power spectrum. Overall we find considerable success in modeling many, but not all, of the terms in this expansion.

description: Background and aims.– Neurocognitive deficits are a core feature of psychotic spectrum disorders. It is commonly accepted in the
 scientific psychiatric community that atients who suffer from a particular psychotic disorder, have a variety of deficits in most
 cognitive functions including executive function, memory and attention. The purpose of the study is to examine neurocognitive
 deficits in a clinical sample of hospitalized patients diagnosed in the psychotic spectrum applying innovative methods of computational intelligence. Methods.– The participants belonged to the category of patients diagnosed in the spectrum of psychosis disorders hospitalized at
 the University Psychiatric Clinic of the General Hospital. Neuropsychological tests and scales such as Wisconsin Sorting Card Task, Key Search, Stroop Test, Digit Span, and phonological/semanticmemory (COWAT) were used to collect the data. Results.– Through the use of specific computational intelligence programs (WEKA, R), Machine Learning Techniques were applied
 by selecting appropriate classification, clustering and correlation algorithms. In addition, the parameters of these algorithms
 were determined, depending on the case, in order to produce conclusions/decision-making rules. Conclusions.– In conclusion, it is underlined the significance of the exported rules that applied via computational intelligence methods
 and are presented in the most understandable and friendly way to the final recipient. The results of the study highlight the clinical significance of the neurocognitive deficits of patients (especially in the executive functions) who are diagnosed in the psychotic spectrum and may also contribute to a better knowledge for the course of the psychosis offering new data for implementation of therapeutic programs of cognitive rehabilitation/psychoeducation.

Paroxyethira asymmetrica

description: Paroxyethira asymmetrica, new species Figs 10–12, 34–36 Most closely similar to P. opposita, new species, with which it shares the feature of male gonopods strongly asymmetric; however, with the right gonopod shorter than the left, in contrast to P. opposita in which the left gonopod is shorter than the right. Paroxyethira asymmetrica is distinguished from other species with markedly unequal gonopods by the very short phallic sheath. The female of P. asymmetrica has terminalia more symmetrical than other congeners, regularly conical in ventral view; the surface is noticeably ‘pocked’ by setal bases; and in dorsal view there is a prominent ‘pocket’ subapically on the right. Male antennae each with 21–22 flagellomeres; female antennae each with 19 flagellomeres. Forewing length. Male 1.7–2.4 mm (n=5); female 1.6–2.0 mm (n=10). Male genitalia (Figs 10–12). Sternite VII bearing short sharp spur medially. Median process on abdominal sternite VIII stoutly spatulate; length about 3x width at middle. Abdominal segment IX with broadly rounded posterolateral lobes; dorsally with distal margin deeply concave. Gonopods unequal, left elongate, slender, ~2.5x length of right; both bearing mesal brushes of stout black setae. Phallic apparatus as for P. dumagnes (Fig. 5), being slender and straight but with distal portion proportionally shorter, constricted at 1/4 length, at which constriction short, threadlike titillator arising. Phallic sheath short, broad; with seta at each apico-lateral angle; on left 2 setaebearing papillae and proximally anteriorly directed apodeme. Female (Figs 34–36). Abdominal sternites VII–VIII fused, broad-based, constricted laterally at about 1/3 length, conical in distal 2/3, almost symmetrical. Tergites VII–VIII dorsally discrete; VIII with prominent ‘pocket’ subapically on right; surface of VII–VIII disrupted by pronounced sockets of scattered fine setae; apex rounded ventrally, concave dorsally. Segment X divided distally to form 2 lobes. Holotype male: Province Sud, Xwé Pemöu Stream, 300 m N bridge over Dathio River at Atè, 6.2 km WNW Thio, 21.58835°S, 166.15117°E, 13 m, 29.xi.2003, light trap, loc#056, leg. K.A. Johanson (MNHP). Paratypes: Same data as for holotype – 5 males, 22 females (SMNH). Etymology: Asymmetrica, named for the strongly asymmetric gonopods of the male genitalia.

Form invariance symmetry generates a large set of FRW cosmologies

description: We show that Einstein's field equations for spatially flat Friedmann-Robertson-Walker (FRW) space times have a form invariance symmetry (FIS) realized by the form invariance transformations (FIT) which are indeed generated by an invertible function of the source energy density. These transformations act on the Hubble expansion rate, the energy density, and pressure of the cosmic fluid; likewise such transformations are endowed with a Lie group structure. Each representation of this group is associated with a particular fluid and consequently a determined cosmology, so that, the FIS defines a set of equivalent cosmological models. We focus our seek in the FIT generated by a linear function because it provides a natural framework to express the duality and also produces a large sets of cosmologies, starting from a seed one, in several contexts as for instance in the cases of a perfect fluid source and a scalar field driven by a potential depending linearly on the scalar field kinetic energy density.

description: We develop a least-squares method for computing the analytic capacity of compact plane sets with piecewise-analytic boundary. The method furnishes rigorous upper and lower bounds which converge to the true value of the capacity. Several illustrative examples are presented. We are led to formulate a conjecture which, if true, would imply that analytic capacity is subadditive. The conjecture is proved in a special case.
