description: Постановка проблемы. Одна из главных тенденций развития современной радиолокации – повышение разрешающей способности РЛС по дальности и угловым координатам. Антенны из-за особенностей конструкций имеют ярко выраженные блестящие точки, по которым может быть проведено распознавание (идентификация) антенн и объектов, на которых они установлены. Поэтому в общем случае антенны должны рассматриваться как пространственно-протяженные объекты, характеризуемые не только эффективной площадью рассеяния (ЭПР), но и локальными радиолокационными характеристиками (РЛХ). Кроме того, исследование локальных источников рассеяния и изучение механизмов их формирования важно для решения задачи снижения радиолокационной заметности антенн.

Цель. Разработать математическую модель оценки локальных РЛХ зеркальных антенн и систем «антенна – обтекатель» и получить на ее основе радиолокационных изображений антенн и систем «антенна – обтекатель» без средств и при применении средств снижения заметности.

Результаты. Рассмотрены локальные РЛХ зеркальных антенн с обтекателями. Разработана математическая модель оценки локальных РЛХ цилиндрических зеркальных антенн без и при использовании средств снижения заметности для совмещенных и разнесенных условий облучения и приема. Математическая модель основана на строгом методе интегральных уравнений и учитывает процессы облучения и рассеяния электромагнитных волн зеркальными антеннами с обтекателями на сетке дискретных частот. Локальные РЛХ зеркальных антенн с обтекателями определяются путем обработки рассеянных полей. Проведена оценка достижимых уровней снижения интенсивностей локальных источников рассеяния зеркальной антенны за счет применения согласованных нагрузок, волноводных фильтров, радиопоглощающих покрытий и частотно-селективных обтекателей в широком диапазоне частот.

Практическая значимость. Установлены основные закономерности формирования локальных источников рассеяния зеркальных антенн с обтекателями и уменьшения их интенсивности за счет применения средств снижения заметности.

description: This paper evaluates the efficacy of a modified Amitradicaine formulation, which incorporates Dextromethorphan, in the treatment of patients diagnosed with H63D Syndrome Types 1 and 3 (Oshtoran Syndrome), characterized by autonomic dysfunctions, hypersympathicotonia, and endogenously induced catecholamine surges. Conducted from March to September, the study involved ten patients experiencing these conditions. Initial treatments followed the conventional Amitradicaine formula, yielding clinical stabilizations within the known range reported before by other authors/clinicians. Notably, three patients, initially receiving Dextromethorphan as an antitussive due to cough, exhibited enhanced stabilization of dysautonomic activities in the autonomic nervous system (ANS). This improvement regressed upon cessation of Dextromethorphan. Following informed consent, these three patients, along with three additional subjects, were readministered Dextromethorphan with Amitradican. The beneficial effect was replicated, indicating a synergistic interaction between Amitradicaine and Dextromethorphan. Consequently, at the clinics of the three authors of this report, Amitradicaine’s formulation has been amended to include Dextromethorphan, creating a composite drug individually tailored for each patient. This innovative approach demonstrates significant potential in enhancing treatment efficacy for patients with H63D Syndrome Types one and three.

description: Here we present new adaptive optics observations of the Quaoar-Weywot system. With these new observations we determine an improved system orbit. Due to a 0.39 day alias that exists in available observations, four possible orbital solutions are available with periods of $\sim11.6$, $\sim12.0$, $\sim12.4$, and $\sim12.8$ days. From the possible orbital solutions, system masses of $1.3-1.5\pm0.1\times10^{21}$ kg are found. These observations provide an updated density for Quaoar of $2.7-5.0{g cm$^{-3}$}$. In all cases, Weywot's orbit is eccentric, with possible values $\sim0.13-0.16$. We present a reanalysis of the tidal orbital evolution of the Quoaor-Weywot system. We have found that Weywot has probably evolved to a state of synchronous rotation, and have likely preserved their initial inclinations over the age of the Solar system. We find that for plausible values of the effective tidal dissipation factor tides produce a very slow evolution of Weywot's eccentricity and semi-major axis. Accordingly, it appears that Weywot's eccentricity likely did not tidally evolve to its current value from an initially circular orbit. Rather, it seems that some other mechanism has raised its eccentricity post-formation, or Weywot formed with a non-negligible eccentricity.

description: We study two Heisenberg-Kitaev t-J-like models on a honeycomb lattice, focusing on the zigzag magnetic phase of Na$_2$IrO$_3$, and investigate hole motion by exact diagonalization and variational methods. The spectral functions are quite distinct from those of cuprates and are dominated by large incoherent spectral weight at high energy, almost independent of the microscopic parameters --- a universal and generic feature for zigzag magnetic correlations. We explain why quasiparticles at low energy are strongly suppressed in the photoemission spectra and determine an analog of a pseudogap. We point out that the qualitative features of the predominantly incoherent spectra obtained within the two different models for the zigzag phase are similar, and they have remarkable similarity to recently reported angular resolved photoemission spectra for Na$_2$IrO$_3$.

description: We study the use of Krylov subspace recycling for the solution of a sequence of slowly-changing families of linear systems, where each family consists of shifted linear systems that differ in the coefficient matrix only by multiples of the identity. Our aim is to explore the simultaneous solution of each family of shifted systems within the framework of subspace recycling, using one augmented subspace to extract candidate solutions for all the shifted systems. The ideal method would use the same augmented subspace for all systems and have fixed storage requirements, independent of the number of shifted systems per family. We show that a method satisfying both requirements cannot exist in this framework. As an alternative, we introduce two schemes. One constructs a separate deflation space for each shifted system but solves each family of shifted systems simultaneously. The other builds only one recycled subspace and constructs approximate corrections to the solutions of the shifted systems at each cycle of the iterative linear solver while only minimizing the base system residual. At convergence of the base system solution, we apply the method recursively to the remaining unconverged systems. We present numerical examples involving systems arising in lattice quantum chromodynamics.

Propagating clade and model uncertainty to confidence intervals of divergence times and branch lengths

description: Confidence intervals of divergence times and branch lengths do not reflect uncertainty about their clades or about the prior distributions and other model assumptions on which they are based. Uncertainty about the clade may be propagated to a confidence interval by multiplying its confidence level by the bootstrap proportion of its clade or by another probability that the clade is correct. (If the confidence level is 95% and the bootstrap proportion is 90%, then the uncertainty-adjusted confidence level is (0.95)(0.90) = 86%.) Uncertainty about the model can be propagated to the confidence interval by reporting the union of the confidence intervals from all the plausible models. Unless there is no overlap between the confidence intervals, that results in an uncertainty-adjusted interval that has as its lower and upper limits the most extreme limits of the models. The proposed methods of uncertainty quantification may be used together.

description: A spectrometer for the measurement of spontaneous Rayleigh-Brillouin scattering line profiles at ultraviolet wavelengths from gas phase molecules has been developed, employing a high-power frequency-stabilized UV laser with narrow bandwidth (2 MHz). The UV light from a frequency-doubled titanium:sapphire laser is further amplified in an enhancement cavity, delivering a 5 Watt UV-beam propagating through the interaction region inside a scattering cell. The design of the RB-scattering cell allows for measurements at gas pressures in the range 0-4 bar and at stably controlled temperatures from -30 to 70 degree Celsius. A scannable Fabry-Perot analyzer with instrument resolution of 232 MHz probes the Rayleigh-Brillouin profiles. Measurements on N2 and SF6 gases demonstrate the high signal-to-noise ratio achievable with the instrument, at the 1% level at the peak amplitude of the scattering profile.

description: Men have lower rates of HIV testing and higher rates of AIDS-related mortality compared to women in sub-Saharan Africa. To assess whether there is an opportunity to increase men’s uptake of testing by correcting misperceptions about testing norms, we compare men’s perceptions of their closest friend’s HIV testing behaviors with the friend’s actual testing self-report using a unique dataset of men sampled within their social networks (n = 59) in Dar es Salaam, Tanzania. We examine the accuracy and bias of perceptions among men who have tested for HIV (n = 391) and compare them to the perceptions among men who never tested (n = 432). We found that testers and non-testers did not differ in the accuracy of their perceptions, though non-testers were strongly biased towards assuming that their closest friends had not tested. Our results lend support to social norms approaches designed to correct the biased misperceptions of non-testers to promote men’s HIV testing.

description: Trypanosoma cruzi is a protozoan parasite transmitted by a reduviid insect vector and is the causative agent of Chagas disease in humans. 30% of chronic Chagas patients will suffer cardiac and gastrointestinal failure due to parasite-induced tissue destruction. Current therapeutics are ineffective in treating chronic Chagas, underscoring the need for development of novel therapeutics. A promising area of research for drug development is targeting the unique repertoire of ion channels expressed by T. cruzi, proteins that mediate ion flow and are essential for life. Previous work on a mechanosensitive ion channel in T. cruzi revealed that its ablation produced defects in replication and motility, suggestive of a link between mechanosensation and metabolism. Transcriptomic analysis demonstrated these mutants had significantly decreased levels of transcripts encoding a putative Voltage Dependent Anion Channel (VDAC), whose essential functions in mitochondrial metabolism and ionic signaling are well-documented in other organisms but were unexamined in T. cruzi. To begin exploring the link between mechanosensation and metabolism, CRISPR/Cas9 methodologies were used to downregulate TcVDAC expression, which led to defects in replication, cellular and mitochondrial morphology, mitochondrial membrane potential and calcium uptake, and cellular ATP production. These findings indicate conserved roles for VDAC regarding metabolism and mitochondrial ion flux, while pointing to novel roles in maintenance of cellular and mitochondrial morphology in trypanosomes. Further study on the unique structural and functional properties of TcVDAC may reveal divergences from mammalian orthologues for selective targeting by therapeutics.

description: We investigate holographic superconductors in asympototically geometries with hyperscaling violation. The mass of the scalar field decouples from the UV dimension of the dual scalar operator and can be chosen as negative as we want, without disturbing the Breitenlohner-Freedman bound. We first numerically find that the scalar condenses below a critical temperature and a gap opens in the real part of the conductivity, indicating the onset of superconductivity. We further analytically explore the effects of the hyperscaling violation on the superconducting transition temperature. We find that the critical temperature increases with the increasing of hyperscaling violation.

description: The importance of youth engagement in designing, implementing and evaluating programs has garnered more attention as international initiatives seek to address the HIV crisis among this population. Adolescents, however, are not often included in HIV implementation science research and have not had opportunities to contribute to the development of HIV-related research agendas. Project Supporting Operational AIDS Research (SOAR), a United States Agency for International Development-funded global operations research project, involved youth living with HIV in a meeting to develop a strategic implementation science research agenda to improve adolescent HIV care continuum outcomes, including HIV testing and counseling (HTC) and linkage to care.
Inexistence of equilibrium states at absolute negative temperatures

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We show that states of macroscopic systems with purported absolute negative temperatures are not stable under small, yet arbitrary, perturbations. We prove the previous statement using the fact that, in equilibrium, the entropy takes its maximum value. We discuss that, while Ramsey theoretical reformulation of the Second Law for systems with negative temperatures is logically correct, it must be a priori assumed that those states are in thermodynamic equilibrium. Since we argue that those states cannot occur, reversible processes are impossible and, thus, Ramsey identification of negative absolute temperatures is untenable.

In the current study, we investigate the ability of WIV1-CoV to infect Rousettus aegyptiacus bats. No
clinical signs were observed throughout the experiment. Furthermore, only four oropharyngeal swabs
and two respiratory tissues, isolated on day 3 post inoculation, were found positive for viral RNA.
Two out of twelve bats showed a modest increase in coronavirus specific antibodies post challenge.
In conclusion, WIV1-CoV was unable to cause a robust infection in Rousettus aegyptiacus bats.

A new, globally convergent Riemannian conjugate gradient method

Publisher: name: arXiv
Year: 2013
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: This article deals with the conjugate gradient method on a Riemannian manifold with interest in global convergence analysis. The existing conjugate gradient algorithms on a manifold endowed with a vector transport need the assumption that the vector transport does not increase the norm of tangent vectors, in order to confirm that generated sequences have a global convergence property. In this article, the notion of a scaled vector transport is introduced to improve the algorithm so that the generated sequences may have a global convergence property under a relaxed assumption. In the proposed algorithm, the transported vector is rescaled in case its norm has increased during the transport. The global convergence is theoretically proved and numerically observed with examples. In fact, numerical experiments show that there exist minimization problems for which the existing algorithm generates divergent sequences, but the proposed algorithm generates convergent sequences.

Second, we found quadrupole moments of the first $2^+$ states in the same two chains of isotopes. Finally, we evaluated quadrupole moments of odd-odd nuclei neighboring to double magic ones. Reasonable agreement with available experimental data has been obtained. Predictions are made for quadrupole moments of nuclei in the vicinity of unstable magic nuclei

description: Classical and quantum theory of spin waves in the vortex state of a mesoscopic sub-micron magnetic disk has been developed with account of the finite mass density of the vortex. Oscillations of the vortex core resemble oscillations of a charged string in a potential well in the presence of the magnetic field. Conventional gyroscopic frequency appears as a gap in the spectrum of spin waves of the vortex. The mass of the vortex has been computed that agrees with experimental findings. Finite vortex mass generates a high-frequency branch of spin waves. Effects of the external magnetic field and dissipation have been addressed.

description: Постановка проблемы. В настоящее время уделяется значительное внимание развитию труднодоступных районов в целях добычи полезных ископаемых, освоения новых транспортных путей и развития инфраструктуры. Актуальными становятся задачи обеспечения электромагнитной совместимости множества радиоэлектронных средств, эффективного использования ограниченного радиочастотного ресурса, а также высокой степени физической защиты применяемых антенно-фидерных устройств.

Цель. Разработать защищенные конструкции широкополосных пластинчатых дублет-антенн (ДА) для средств и комплексов радиорелейной связи, размещенных у границы материальных сред «воздух – земля».

Результаты. Предложены технические решения, позволяющие улучшить электрические характеристики и защищенность перспективных пластинчатых антенн, размещенных в районах (зонах) с экстремальными условиями эксплуатации. Приведены конструкции двух новых ДА и указаны их отличия от известных ДА. Показано, что при использовании первого варианта конструкции ДА достигается снижение неравномерности распределения тока вдоль проводников ДА в рабочем диапазоне частот и улучшение согласования с питающим фидером. Кроме того, экспериментально доказано увеличение коэффициента усиления антенны на 25–30% и коэффициента бегущей волны на 15–20%. Установлено, что при использовании второго варианта конструкции ДА возможно получить следующие основные технические результаты: уменьшение геометрических размеров (ширины) новой конструкции ДА до величины ширины площадок ее практического размещения на различных мобильных и стационарных объектах связи; снижение неравномерности распределения тока вдоль проводников ДА в рабочем диапазоне частот; улучшение согласования с питающим фидером; увеличение в среднем на 10–15% коэффициента усиления антенны и коэффициента бегущей волны.

Практическая значимость. Практическая ценность предложенных новых конструкций антенн заключается в увеличении дальности интервалов радиорелейной связи до 15–20%, увеличении основных электрических характеристик антенн, размещении антенн как на стационарных объектах, так и на металлических крышах подвижных объектов.

description: This publication will deal with an explicit determination of the time evolution of the spin orientation axes and the evolution of the orbital phase in the case of circular orbits under next-to-leading order spin-orbit interactions. We modify the method of Schneider and Cui proposed in ["Theoreme über Bewegungsintegrale und ihre Anwendungen in Bahntheorien", Verlag der Bayerischen Akademie der Wissenschaften, volume 212, 2005.] to iteratively remove oscillatory terms in the equations of motion for different masses that were not present in the case of equal masses. Our smallness parameter is chosen to be the difference of the symmetric mass ratio to the value 1/4. Before the first Lie transformation, the set of conserved quantities consists of the total angular momentum, the amplitudes of the orbital angular momentum and of the spins, $L, S_1,$ and $S_2$. In contrary, the magnitude of the total spin $S=|S_1+S_2|$ is not conserved and we wish to shift its non-conservation to higher orders of the smallness parameter. We perform the iterations explicitly to first order, while performing higher orders would mean no structural difference or harder mathematical difficulties. To apply this method, we develop a canonical system of spin variables reduced by the conservation law of total angular momentum, which is imposed on the phase space as a constraint. The result is an asymptotic series in $ε$ that may be truncated appropriately considering the physical properties of the regarded system.

description: Chalcogenide materials have received great attention in the last decade owing to their application in new memory systems. Recently, phase-change memories have, in fact, reached the early stages of production. In spite of the industrial exploitation of such materials, the physical processes governing the switching mechanism are still debated. In this paper we work out a complete and consistent model for transport in amorphous chalcogenide materials based on trap-limited conduction accompanied by carrier heating. A previous model is here extended to include position-dependent carrier concentration and field, consistently linked by the Poisson equation. The results of the new model reproduce the experimental electrical characteristics and their dependences on the device length and temperature. Furthermore, the model provides a sound physical interpretation of the switching phenomenon and is able to give an estimate of the threshold condition in terms of the material parameters, a piece of information of great technological interest.

description: This paper evaluates the efficacy of a modified Amitradicaine formulation, which incorporates Dextromethorphan, in the treatment of patients diagnosed with H63D Syndrome Types 1 and 3 (Oshtoran Syndrome), characterized by autonomic dysfunctions, hypersympathicotonia, and endogenously induced catecholamine surges. Conducted from March to September, the study involved ten patients experiencing these conditions. Initial treatments followed the conventional Amitradicaine formula, yielding clinical stabilizations within the known range reported before by other authors/clinicians. Notably, three patients, initially receiving Dextromethorphan as an antitussive due to cough, exhibited enhanced stabilization of dysautonomic activities in the autonomic nervous system (ANS). This improvement regressed upon cessation of Dextromethorphan. Following informed consent, these three patients, along with three additional subjects, were readministered Dextromethorphan with Amitradican. The beneficial effect was replicated, indicating a synergistic interaction between Amitradicaine and Dextromethorphan. Consequently, at the clinics of the three authors of this report, Amitradicaine’s formulation has been amended to include Dextromethorphan, creating a composite drug individually tailored for each patient. This innovative approach demonstrates significant potential in enhancing treatment efficacy for patients with H63D Syndrome Types one and three.

description: The problem of maximizing weighted sum rates in the downlink of a multicell environment is of considerable interest. Unfortunately, this problem is known to be NP-hard. For the case of multi-antenna base stations and single antenna mobile terminals, we devise a low complexity, fast and provably convergent algorithm that locally optimizes the weighted sum rate in the downlink of the system. In particular, we derive an iterative second-order cone program formulation of the weighted sum rate maximization problem. The algorithm converges to a local optimum within a few iterations. Superior performance of the proposed approach is established by numerically comparing it to other known solutions.

У лиц моложе 50 лет не было выявлено перенесенных ишемических инсультов в 87% наблюдений, этот показатель уменьшался вдвое в возрасте от 50 до 60 лет и сохранялся у лиц старше 60 лет. Таким образом, наиболее уязвимым возрастным периодом в отношении развития инсульта является возраст старше 52,6 лет.
Constraining the symmetry energy at subsaturation densities using isotope binding energy difference and neutron skin thickness

description: We show that the neutron skin thickness $Δr_{np}$ of heavy nuclei is uniquely fixed by the symmetry energy density slope $L(ρ)$ at a subsaturation cross density $ρ_c \approx 0.11$ fm$^{-3}$ rather than at saturation density $ρ_0$, while the binding energy difference $ΔE$ between a heavy isotope pair is essentially determined by the magnitude of the symmetry energy $E_{\text{sym}}(ρ)$ at the same $ρ_c$. Furthermore, we find a value of $L({ρ_c})$ leads to a negative $E_{\text{sym}}({ρ_{0}})$-$L({ρ_{0}})$ correlation while a value of $E_{\text{sym}}({ρ_{c})}$ leads to a positive one. Using data on $Δr_{np}$ of Sn isotopes and $ΔE$ of a number of heavy isotope pairs, we obtain simultaneously $E_{\text{sym}}({ρ_{c})}=26.65\pm0.20$ MeV and $L({ρ_c})= 46.0\pm4.5$ MeV at 95% confidence level, whose extrapolation gives $E_{\text{sym}}({ρ_{0}})=32.3\pm1.0$ MeV and $L({ρ_{0}})=45.2\pm10.0$ MeV. The implication of these new constraints on the $Δr_{np}$ of $^{208}$Pb and the core-crust transition density in neutron stars is discussed.

description: We propose how to realize high-fidelity quantum storage using a hybrid quantum architecture including two coupled flux qubits and a nitrogen-vacancy center ensemble (NVE). One of the flux qubits is considered as the quantum computing processor and the NVE serves as the quantum memory. By separating the computing and memory units, the influence of the quantum computing process on the quantum memory can be effectively eliminated, and hence the quantum storage of an arbitrary quantum state of the computing qubit could be achieved with high fidelity. Furthermore the present proposal is robust with respect to fluctuations of the system parameters, and it is experimentally feasibile with currently available technology.

description: We study the collective modes in relativistic electromagnetic or quark-gluon plasmas with an asymmetry between left- and right-handed chiral fermions, based on the recently formulated kinetic theory with Berry curvature corrections. We find that there exists an unstable mode, signaling the presence of a plasma instability. We argue the fate of this "chiral plasma instability" including the effect of collisions, and briefly discuss its relevance in heavy ion collisions and compact stars.

description: We review the physics of confinement based on non-Abelian dual superconductor picture, relying on exact solutions in N=2 supersymmetric QCD and based on the recent developments in our understanding of non-Abelian vortices and monopoles. The non-Abelian monopoles, though they are basically just the 't Hooft-Polyakov SU(2) monopoles embedded in various corners of the larger gauge group, require flavor symmetry in an essential way for their very existence. The phenomenon of flavor-color-flavor separation characterizes the multiple roles flavor symmetry plays in producing quantum-mechanical non-Abelian monopoles.
