description: We previously reported the chaos induced by the frustration of interaction in a non-monotonic sequential associative memory model, and showed the chaotic behaviors at absolute zero. We have now analyzed bifurcation in a stochastic system, namely a finite-temperature model of the non-monotonic sequential associative memory model. We derived order-parameter equations from the stochastic microscopic equations. Two-parameter bifurcation diagrams obtained from those equations show the coexistence of attractors, which do not appear at absolute zero, and the disappearance of chaos due to the temperature effect.

description: A 1-D loop radiative hydrodynamic model that incorporates the effects of gravitational stratification, heat conduction, radiative losses, external heat input, presence of helium, and Braginskii viscosity is used to simulate elementary flare loops. The physical parameters for the input are taken from observations of the Bastille-Day flare of 2000 July 14. The present analysis shows that: (a) The obtained maximum values of the electron density can be considerably higher (4.2 X 10^{11} cm^{-3} or more) in the case of footpoint heating than in the case of apex heating (2.5 X 10^{11} cm^{-3}). (b) The average cooling time after the flare peak takes less time in the case of footpoint heating than in the case of apex heating. (c) The peak apex temperatures are significantly lower (by about 10 MK) for the case of footpoint heating than for apex heating (for the same average loop temperature of about 30 MK). This characteristic allows us to discriminate between different heating positioning. (d) In both cases (of apex and footpoint heating), the maximum obtained apex temperature T^{max} is practically independent of the heating duration sigma_{t}, but scales directly with the heating rate E_{H0}. (e) The maximum obtained densities at the loop apex, n_e^{max}, increase with the heating rate E_{H0} and heating duration sigma_{t} for both footpoint and apex heating. In Paper II we will use the outputs of these hydrodynamic simulations, which cover a wide range of the parameter space of heating rates and durations, as an input for forward-fitting of the multi-loop arcade of the Bastille-day flare.

Traveling skyrmions in chiral antiferromagnets

description: Skyrmions in antiferromagnetic (AFM) materials with the Dzyaloshinskii-Moriya (DM) interaction are expected to exist for essentially the same reasons as in DM ferromagnets (FM). It is shown that skyrmions in antiferromagnets with the DM interaction can be traveling as solitary waves with velocities up to a maximum value that depends on the DM parameter. Their configuration is found numerically. The energy and the linear momentum of an AFM skyrmion lead to a proper definition of its mass. We give the details of the energy-momentum dispersion of traveling skyrmions and explore their particle-like character based on exact relations. The skyrmion number, known to be linked to the dynamics of topological solitons in FM, is, here, unrelated to the dynamical behavior. As a result, the solitonic behavior of skyrmions in AFM is in stark contrast to the dynamical behavior of their FM counterparts

 Litocladius mateusi Mendes, Andersen and Saether, 2004: 74, Figs 21–23.
 Material examined: Type material as in Mendes et al. (2004).
 Diagnostic characters: The species can be separated from the two other members of the genus by absence of spines on third palpomere, wing veins and membrane bare, inferior volsella with rounded oral projection, and by having a distinct crista dorsalis.
 Remarks: This species was originally described with two types of acrostichals. Reexamination of the holotype reveals that the anteriormost acrostichals had fallen off, but the size of the seta bases indicate that the acrostichals most probably can be subdivided into three groups: anterior strong decumbent, middle simple weak, and posterior scalpellate, as in the other two species included in the genus.
 Biology and distribution: This species was collected among mosses on tree trunks and is described as male, female and pupa. The larvae could not be found, but is certainly terrestrial. The species is only known from the type locality in São Paulo State, Brazil.

description: A growth model and parameters obtained in our previous experimental (scanning tunneling microscopy, KMC) and theoretical (kinetic Monte Carlo simulations, KMC) studies of Ag/Si(111)-(7x7) heteroepitaxy were used to optimise growth conditions (temperature and deposition rate) for the most ordered self-organized growth of Ag island arrays on the (7x7) reconstructed surface. The conditions were estimated by means of KMC simulations using the preference in occupation of half unit cells (HUCs) of F-type as a criterion of island ordering. Morphology of experimentally prepared island structures was studied by STM. High degree of experimentally obtained island ordering is compared with the simulated data and results are discussed with respect to the model and parameters used at the KMC simulations.

description: We show that topology optimization (TO) of metallic resonators can lead to $\sim 10^2\times$ improvement in surface-enhanced Raman scattering (SERS) efficiency compared to traditional resonant structures such as bowtie antennas. TO inverse design leads to surprising structures very different from conventional designs, which simultaneously optimize focusing of the incident wave and emission from the Raman dipole. We consider isolated metallic particles as well as more complicated configurations such as periodic surfaces or resonators coupled to dielectric waveguides, and the benefits of TO are even greater in the latter case. Our results are motivated by recent rigorous upper bounds to Raman scattering enhancement, and shed light on the extent to which these bounds are achievable.

Frictional magnetodrag between spatially separated two-dimensional electron systems: Coulomb versus phonon mediated electron-electron interaction

description: We study the frictional drag due to Coulomb and phonon mediated electron-electron interaction in a double layer electron system exposed to a perpendicular magnetic field. Within the random phase approximation we calculate the dispersion relation of the intra Landau level magnetoplasmons at finite temperatures and distinguish their contribution to the magnetodrag. We calculate the transresistivity $ρ_{Drag}$ as a function of magnetic field $B$, temperature $T$, and interlayer spacing $Λ$ for a matched electron density. For $Λ=200$ nm we find that $ρ_{Drag}$ is solely due to phonon exchange and shows no double-peak structure as a function of $B$. For $Λ=30$ nm, $ρ_{Drag}$ shows the double-peak structure and is mainly due to Coulomb interaction. The value of $ρ_{Drag}$ is about 0.3 $Ω$ at T=2 K and for the half-filled second Lanadau level, which is about 13 times larger than the value for $Λ=200$ nm. At lower edge of the temperature interval from 0.1 to 8 K, $ρ_{Drag}/ T^{2}$ remains finite for $Λ=30$ nm while it tends to zero for $Λ=200$ nm. Near the upper edge of this interval, $ρ_{Drag}$ for $Λ=30$ nm is approximately linear in $T$ while for $Λ=200$ nm it decreases slowly in $T$. Therefore, the peak of $ρ_{Drag}/ T^{2}$ is very sharp for $Λ=200$ nm. This strikingly different magnetic field and temperature dependence of $ρ_{Drag}$ ascribe we mainly to the weak screening effect at large interlayer separations.

We demonstrate that exclusive pion production in $un$polarized electron-proton scattering in the forward region is a direct probe of the gluon Sivers function due to its connection to the QCD Odderon.

description: Economic analysts have expressed significant interest in the transition of the industrial base towards knowledge-intensive production. A central aspect of this transition is the growth and development of industries that provide the technological and scientific foundations for what is often termed the New Economy. This empirical study develops a geographic profile of New Economy industries in Canada across the urban/rural hierarchy and in different metropolitan areas between 1990 and 2000. The study also investigates whether measures of agglomeration economies are correlated with the increased incidence of New Economy industries across different locations over the study period. The study shows that the employment growth in New Economy industries through the 1990s has been primarily an urban phenomenon and that agglomeration economies have played an increasingly important role in the formation of these industries.

description: Recently Mayer et al. [Phys. Rev. E {\bf 68}, 016116 (2003)] proposed a new way to compute numerically the fluctuation-dissipation ratios in nonequilibrium critical systems. Using well-known facts of nonequilibrium critical dynamics I show that the leading contributions of the quantities they consider are in fact one-time quantities which are independent of the waiting time. The ratio of these one-time quantities determines the slope of the straight lines observed in the fluctuation-dissipation plots of Mayer et al.

description: We introduce a new approach that allows one complete control over the modulation of the effective twist angle change in few-layer van der Waals heterostructures by irradiating them with longitudinal waves of light at the end of a waveguide. As a specific application, we consider twisted bilayer graphene and show that one can tune the magic angles to be either larger or smaller, allowing in-situ experimental control of the phase diagram of this and other related materials. A waveguide allows one to circumvent the free-space constraints on the absence of longitudinal electric field components of light. We propose to place twisted bilayer graphene at a specific location at the exit of a waveguide, such that it is subjected to purely longitudinal components of a transverse magnetic modes (TM) wave.
Low-redshift constraints on homogeneous and isotropic universes with torsion

description: One of the possible extensions of Einstein's General Theory of Relativity consists in allowing for the presence of spacetime torsion. The form of the underlying torsion tensor can be chosen such that the homogeneity and isotropy of Friedmann-Lemaitre-Robertson-Walker universes is preserved, and it has been recently suggested that such universes may undergo accelerating phases. We use recent low-redshift data, coming from Type Ia Supernova and Hubble parameter measurements, to phenomenologically constrain this class of models under the so-called steady-state torsion assumption of a constant fractional contribution of torsion to the volume expansion. We start by considering models without a cosmological constant (where torsion itself would be expected to yield the current acceleration of the universe) finding, in agreement with other recent works, that these are strongly disfavoured by the data. We then treat these models as one-parameter extensions of $Λ$CDM, constraining the relative contribution of torsion to the level of a few percent in appropriate units. Finally, we briefly discuss how these constraints may be improved by forthcoming low-redshift data and check the robustness of our results by studying an alternative to the steady-state torsion parametrization.

description: We precisely measured the binding energy of a molecular state near the Feshbach resonance in a $^{85}$Rb Bose-Einstein condensate (BEC). Rapid magnetic field pulses induced coherent atom-molecule oscillations in the BEC. We measured the oscillation frequency as a function of B-field and fit the data to a coupled-channels model. Our analysis constrained the Feshbach resonance position [155.041(18) G], width [10.71(2) G], and background scattering length [-443(3) a$_0$] and yielded new values for $v_{DS}$, $v_{DT}$, and $C_6$. These results improved our estimate for the stability condition of an attractive BEC. We also found evidence for a mean-field shift to the binding energy.

Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

description: This study examines changes in Nashville’s labor market following the April 16, 1998 tornado. Specifically, the study focuses on whether or not employment growth experienced a change in mean around the time of the tornado. A time series intervention model that allows for timevarying variance is used to examine the labor market dynamics associated with the impact of the tornado and the ensuing recovery process. The analysis of employment growth is conducted at the aggregate (overall) level as well as for seven industrial sectors. The empirical findings may be summarized as follows. The aggregate Nashville labor market, along with manufacturing, service, transportation and public utilities, and wholesale, retail trade sectors, experienced a more stable employment growth rate in the post-tornado period. Employment in the construction and mining and government sectors exhibited no evidence of change between the pre- and post-tornado periods. Employment growth in the finance, insurance, and real estate sector was lower in the posttornado period than in the pre-tornado period, while employment growth in the transportation and public utilities sector significantly increased in the period following the tornado.

Lectotype (designated by Pohle 1943: 323; erroneously considered as holotype by Topal 1997): ZMB 4146, skin and skull (probably extracted before 1943 by Pohle), female; Amoy (= Xiamen, Fujian), China; collected by Swinhoe, July 1867, donated by Swinhoe between 20 March and 14 April 1870.
 Comment: Peters described Vespertilio laniger on the basis of a complete specimen out of a series of three specimens, which fits the form of the specimen ZMB 4146. Dobson (1878: 299) identified a skin in the BMNH as a “ type ”. Pohle (1943: 321) suggested the skin (“c”) in the BMNH that was collected by Swinhoe and listed by Dobson (1878: 299) as “ type ” because its data was identical to that of specimens sent by the collector to Peters, had no nomenclaturial status, since it was possible it was purchased from Swinhoe after Peters had described the species. The third specimen probably remained in the private collection of Swinhoe and its whereabouts are unknown.

description: Low-frequency radio surveys allow in-depth studies and new analyses of classes of sources previously known and characterised only in other bands. In recent years, low radio frequency observations of blazars have been available thanks to new surveys, such as the GaLactic and Extragalactic All-sky MWA Survey (GLEAM). We search for gamma-ray blazars in a low frequency ($ν$ < 240MHz) survey, to characterise the spectral properties of the spatial components. We cross-correlate GLEAM with the fourth catalogue of active galactic nuclei (4LAC) detected by the Fermi satellite. This improves over previous works using a low frequency catalogue that is wider, deeper, with a better spectral coverage and the latest and most sensitive gamma-ray source list. In comparison to the previous study based on the commissioning survey, the detection rate increased from 35% to 70%. We include Australia Telescope 20GHz (AT20G) Survey data to extract high-frequency high-angular resolution information on the radio cores of blazars. We find low radio frequency counterparts for 1274 out of 1827 blazars in the 72-231 MHz range. Blazars have at spectrum at $\sim$ 100MHz regime, with a mean spectral index $α$ = -0.44 +-0.01 (assuming S $\propto$ $ν^ α$ ). Low synchrotron peaked objects have a scatter spectrum than high synchrotron peaked objects. Low frequency radio and gamma-ray emission show a significant but scattered correlation. The ratio between lobe and core radio emission in gamma-ray blazars is smaller than previously estimated.

description: As is well known, h-vectors of simple (or simplicial) convex polytopes are characterized. In fact, those h-vectors must satisfy Dehn-Sommerville equations and some other inequalities. Simple convex polytopes determine Gorenstein* simplicial posets and h-vectors are defined for simplicial posets. It is known that h-vectors of Gorenstein* simplicial posets must satisfy Dehn-Sommerville equations and that every component in the h-vectors must be non-negative. In this paper we will show that h-vectors of Gorenstein* simplicial posets must satisfy one more subtle condition conjectured by R. Stanley and complete characterization of those h-vectors. Our proof is purely algebraic but the idea of the proof stems from topology.

description: We leverage recent breakthroughs in neural density estimation to propose a new unsupervised anomaly detection technique (ANODE). By estimating the probability density of the data in a signal region and in sidebands, and interpolating the latter into the signal region, a likelihood ratio of data vs. background can be constructed. This likelihood ratio is broadly sensitive to overdensities in the data that could be due to localized anomalies. In addition, a unique potential benefit of the ANODE method is that the background can be directly estimated using the learned densities. Finally, ANODE is robust against systematic differences between signal region and sidebands, giving it broader applicability than other methods. We demonstrate the power of this new approach using the LHC Olympics 2020 R\&D Dataset. We show how ANODE can enhance the significance of a dijet bump hunt by up to a factor of 7 with a 10\% accuracy on the background prediction. While the LHC is used as the recurring example, the methods developed here have a much broader applicability to anomaly detection in physics and beyond.

description: A correct understanding and description of the I=2 pi-pi S-wave interaction is important for the extraction of the I=0 pi-pi S-wave interaction from experimental data and for understanding the I=0 pi-pi S-wave interaction theoretically. With t-channel rho, f2(1270) exchange and the pi pi -> rho rho -> pi pi box diagram contribution, we reproduce the pi-pi isotensor S-wave and D-wave scattering phase shifts and inelasticities up to 2.2 GeV quite well in a K-matrix formalism.

description: Objective: To compare risk of hepatotoxicity between various regimens for reintroduction of antitubercular therapy (ATT) in patients with previous episode of ATT hepatitis. Methods: We searched various databases (PubMed, Embase, CENTRAL, Scopus, WoS and LILACS) for studies comparing ATT reintroduction regimens using terms ‘drug-induced liver injury’ and ‘antitubercular drugs’ AND ‘reintroduction’. The reintroduction regimens i.e concomitant (all drugs introduced together), sequential (reintroduction of one drug in full dose followed by another) or incremental (one drug in a low dose and then higher dose followed by next drug) were compared using Bayesian approach for network meta-analysis with random-effect model. Cochrane revised tool was used to assess risk of bias in included studies (RoB 2.0). Results: Four randomized studies with 577 patients were eligible for analysis. Compared with concomitant regimen (baseline comparator), incremental regimen appeared to have lower risk of ATT hepatitis (odds ratio [OR] 0.24; 95% CrI 0.017, 1.2) as also the sequential regimen (OR 0.33; 95% CrI 0.033, 1.7). Rifampicin first and isoniazid first reintroduction regimens were similar via-a-vis recurrence of hepatotoxicity. Conclusion: The sequential and incremental regimen may be better than concomitant regimen in reducing risk of ATT hepatitis although the odds did not achieve statistical significance.
Role of lunar laser ranging in realization of terrestrial, lunar, and ephemeris reference frames

description: Three possible applications of lunar laser ranging to space geodesy are studied. First, the determination of daily Earth orientation parameters (UT0 and variation of latitude), which is rarely used nowadays in presence of all-year VLBI, SLR, and GNSS data. The second application is the determination of two (out of three) lunar orientation parameters, i.e. daily corrections to the rotational ephemeris of the Moon. It may be of importance for the future lunar satellite-based navigational systems. The third application is the tie of ephemeris frame (BCRF) to the ICRF. It has been studied before, though in this work it is extensively compared to another realization of the same tie, obtained by spacecraft VLBI observations; also, two different EOP series and two different models of tidal variations of geopotential are applied, with different outcomes on the tie. The EPM lunar-planetary ephemeris, along with its underlying dynamical model and software, was used to obtain the presented results. All available observations were processed, since the earliest made at the end of 1969 at the McDonald observatory till the end of July 2019 (Matera, Grasse and also Wettzell observatory which began to provide data in 2018). The results and some open questions are discussed.
Superfluidity and collective modes in a uniform gas of Fermi atoms with a Feshbach resonance

description: We investigate strong-coupling superfluidity in a uniform gas of Fermi atoms attractively interacting via quasi-molecular bosons associated with a Feshbach resonance. This interaction is tunable by the threshold energy $2ν$ of the Feshbach resonance, becoming large as $2ν$ is decreased. In recent work, we showed that the enhancement of this tunable pairing interaction naturally leads to the BCS-BEC crossover, where the character of the superfluid phase transition changes from the BCS-type to a BEC of composite bosons consisting of preformed Cooper-pairs and Feshbach-induced molecules. In this paper, we extend our previous work and study both single quasi-particles and the collective dynamics of the superfluid phase below Tc. We show how the superfluid order parameter changes from the Cooper-pair amplitude to the square root of the number of condensed molecules associated with the Feshbach resonance, as the threshold energy $2ν$ is lowered. We also discuss the Goldstone mode associated with superfluidity, and show how its character smoothly changes from the Anderson-Bogoliubov phonon in the BCS regime to the Bogoliubov phonon in the BEC regime in the BCS-BEC crossover. This Goldstone mode is shown to appear as a resonance in the spectrum of the density-density correlation function, which is experimentally accessible.

description: We study Floquet eigenspectra of a nonlinear two-mode system under a periodic driving of the off-diagonal coupling. By solving the Gross-Pitaevskii equation numerically, we obtain triangular and loop structures near the crossings of different Floquet branches. At lower driving frequencies, we find "ring" and "double-ring" structures which are distinct from the well-known loop structure. The mechanism of the emergence of these structures is discussed and the parameter windows of their existence are obtained analytically. In addition, we study the evolution of the system under the driving with an adiabatic sweep and find there are some dynamically unstable states in the Floquet eigenspectra which break the quantum adiabaticity.

description: We present spatially resolved X-ray spectra taken with the EPIC cameras of XMM-Newton of a sample of 17 cooling clusters and three non-cooling clusters for comparison. The deprojected spectra are analyzed with a multi-temperature model, independent of any a priori assumptions about the physics behind the cooling and heating mechanisms. All cooling clusters show a central decrement of the average temperature, most of them of a factor of ~2. At each radius within the cooling region the gas is non-isothermal. The differential emission measure distribution peaks near the maximum (ambient) temperature, and steeply declines towards lower temperatures, proportional to T^3, or alternatively a cut-off at about a quarter to half of the maximum temperature. In general, we find a poor correlation between radio flux of the central galaxy and the temperature decrement of the cooling flow. This is interpreted as evidence that except for a few cases heating by a central AGN is not the most common cause of weak cooling flows. We investigate the role of heat conduction by electrons and find that the theoretically predicted conductivity rates are not high enough to balance radiation losses. The differential emission measure distribution has remarkable similarities with the predictions from coronal magnetic loop models. Also the physical processes involved (radiative cooling, thermal conduction along the loops, gravity) are similar for clusters loops and coronal loops. If coronal loop models apply to clusters, we find that a few hundred loops per scale height should be present. The typical loop sizes deduced from the observed emission measure distribution are consistent with the characteristic magnetic field sizes deduced from Faraday rotation measurements.
