description: Rotating relativistic stars are receiving significant attention in recent years, because of the information they can yield about the equation of state of matter at extremely high densities and because they are one of the more possible sources of detectable gravitational waves. We review the latest theoretical and numerical methods for modeling rotating relativistic stars, including stars with a strong magnetic field and hot proto-neutron stars. We also review nonaxisymmetric oscillations and instabilities in rotating stars and summarize the latest developments regarding the gravitational wave-driven (CFS) instability in both polar and axial quasi-normal modes.

description: Quantum error correction has recently emerged as a tool to enhance quantum sensing under Markovian noise. It works by correcting errors in a sensor while letting a signal imprint on the logical state. This approach typically requires a specialized error-correcting code, as most existing codes correct away both the dominant errors and the signal. To date, however, few such specialized codes are known, among which most require noiseless, controllable ancillas. We show here that such ancillas are not needed when the signal Hamiltonian and the error operators commute; a common limiting type of decoherence in quantum sensors. We give a semidefinite program for finding optimal ancilla-free sensing codes in general, as well as closed-form codes for two common sensing scenarios: qubits undergoing dephasing, and a lossy bosonic mode. Finally, we analyze the sensitivity enhancement offered by the qubit code under arbitrary spatial noise correlations, beyond the ideal limit of orthogonal signal and noise operators.

description: Integrations in fixed N-body realisations of smooth density distributions corresponding to a chaotic galactic potential can be used to derive reliable estimates of the largest (finite time) Lyapunov exponent X_S associated with an orbit in the smooth potential generated from the same initial condition, even though the N-body orbit is typically characterised by an N-body exponent X_N >> X_S. This can be accomplished either by comparing initially nearby orbits in a single N-body system or by tracking orbits with the same initial condition evolved in two different N-body realisations of the same smooth density.

description: This paper concerns an Information Extraction process for building a dynamic Legislation Network from legal documents. Unlike supervised learning approaches which require additional calculations, the idea here is to apply Information Extraction methodologies by identifying distinct expressions in legal text and extract quality network information. The study highlights the importance of data accuracy in network analysis and improves approximate string matching techniques for producing reliable network data-sets with more than 98 percent precision and recall. The values, applications, and the complexity of the created dynamic Legislation Network are also discussed and challenged.

description: The future electron-proton collider proposals, LHeC and FCC-he, can deliver $\mathcal{O}$(TeV) center-of-mass energy collisions, higher than most of the proposed lepton accelerators, with $\mathcal{O}$(ab$^{-1}$) luminosity, while maintaining a much cleaner experimental environment as compared to the hadron machines. This unique capability of $e^- p$ colliders can be harnessed in probing BSM scenarios giving final states that look like hadronic noise at $pp$ machines. In the present study, we explore the prospects of detecting such a prompt signal having multiple soft jets at the LHeC. Such a signal can come from the decay of gluino in RPV or Stealth SUSY, where there exists a gap in the current experimental search with $m_{\tilde{g}} \approx 50 - 70$ GeV. We perform a simple analysis to demonstrate that, with simple signal selection cuts, we can close this gap at the LHeC at 95 % confidence level, even in the presence of a reasonable systematic error. More sophisticated signal selection strategies and detailed knowledge of the detector can be used to improve the prospects of signal detection.

Fermionic entropy of the vortex state in d-wave superconductors
Creators: name: Volovik, G. E.
Publisher: name: arXiv
Year: 1997
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: In the d-wave superconductors the electronic entropy associated with an isolated vortex diverges logarithmically with the size of the system even at low temperatures. In the vortex array the entropy per vortex per layer, $S_V$, is much larger than $k_B$ and depends on the distribution of the velocity field $v_s$ around the vortex. If there is a first order transition with the change of the velocity distribution, then there will be a big entropy jump $ΔS_V \sim 1 k_B$ at the transition. This entropy jump comes from the electronic degrees of freedom on the vortex background, which is modified by the vortex transition. This can explain the big jump in the entropy observed in the so-called vortex-melting transition [A. Junod, et. al., Physica C 27, 245 (1997)], in which the vortex array and thus the velocity field are redistributed. The possibility of the Berezinskii- Kosterlitz-Thouless transition in the 3-dimensional d-wave superconductor due to the fermionic bound states in the vortex background is discussed.

description: We show that the quantum dynamics of a real scalar field for a large class of potentials in the symmetric Gaussian state, where the nonperturbative quantum contributions are taken into account, can be described equivalently by a two-dimensional nonlinear dynamical system with a definite angular momentum (U(1) charge of a complex theory). It is found that the Gaussian state with a nearly minimal uncertainty and a large quantum fluctuation, as an initial condition, naturally explains the most of the essential features of the early stage of the inflationary Universe.

Orbital-to-Spin Angular Momentum Conversion Employing Local Helicity

description: Spin-orbit interactions in optics traditionally describe an influence of the polarization degree of freedom of light on its spatial properties. The most prominent example is the generation of a spin-dependent optical vortex upon focusing or scattering of a circularly polarized plane-wave by a nanoparticle, converting spin to orbital angular momentum of light. Here, we present a mechanism of conversion of orbital-to-spin angular momentum of light upon scattering of a linearly polarized vortex beam by a spherical silicon nanoparticle. We show that focused linearly polarized Laguerre-Gaussian beams of first order ($\ell = \pm 1$) exhibit an $\ell$-dependent spatial distribution of helicity density in the focal volume. By using a dipolar scatterer the helicity density can be manipulated locally, while influencing globally the spin and orbital angular momentum of the beam. Specifically, the scattered light can be purely circularly polarized with the handedness depending on the orbital angular momentum of the incident beam. We corroborate our findings with theoretical calculations and an experimental demonstration. Our work sheds new light on the global and local properties of helicity conservation laws in electromagnetism.

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The under-abundance of asteroids on orbits with small perihelion distances suggests that thermally-driven disruption may be an important process in the removal of rocky bodies in the Solar System. Here we report our study of how the debris streams arise from possible thermally-driven disruptions in the near-Sun region. We calculate that a small body with a diameter $\gtrsim0.5$ km can produce a sufficient amount of material to allow the detection of the debris at the Earth as meteor showers, and that bodies at such sizes thermally disrupt every $\sim2$ kyrs. We also find that objects from the inner parts of the asteroid belt are more likely to become Sun-approacher than those from the outer parts. We simulate the formation and evolution of the debris streams produced from a set of synthetic disrupting asteroids drawn from Granvik et al. (2016)'s near-Earth object population model, and find that they evolve 10--70 times faster than streams produced at ordinary solar distances. We compare the simulation results to a catalog of known meteor showers on Sun-approaching orbits. We show that there is a clear overabundance of Sun-approaching meteor showers, which is best explained by a combining effect of comet contamination and an extended disintegration phase that lasts up to a few kyrs. We suggest that a few asteroid-like Sun-approaching objects that brighten significantly at their perihelion passages could, in fact, be disrupting asteroids. An extended period of thermal disruption may also explain the widespread detection of transiting debris in exoplanetary systems.

description: In our previous paper [Phys. Rev. E 95, 062122 (2017)] we considered the optical channel modelled by the nonlinear Schrödinger equation with zero dispersion and additive Gaussian noise. We found per-sample channel capacity rof this model. In the present paper we extend per-sample model by introducing the initial signal dependence on time and the output signal detection procedure. The proposed model is a closer approximation of the realistic communication link than the per-sample model where there is no dependence of the initial signal on time. For the proposed model we found the correlators of the output signal both analytically and numerically. Using these correlators we built the conditional probability density function. Then we calculated an entropy of the output signal, a conditional entropy, and the mutual information. Maximizing the mutual information we found the optimal input signal distribution, channel capacity? and their dependence on the shape or the initial signal in the time domain for the intermediate power range.

description: Water Users Association (WUAs) is one of the methods of participatory water resource management whose success and efficiency requires the participation of farmers. Purpose of this study was to identify and prioritize the solutions for farmers’ participation enhancing in WUAs. This exploratory article was carried out by the mixed methods design. The qualitative part of the study was conducted by Grounded Theory (GT). The statistical population consisted of 14 key informant experts of water resources management. Data were gathered by semi-structured interview. The triangulation of peers in different position was used to enhance the accuracy of the data. Categories were derived from interviews by MAXQDA 12 software. In the quantitative phase, 133 members of WUAs were sampled in Lorestan Province (N=1990) using the Cochran formula. Solutions proposed by experts were provided to the members of WUAs in the form of a questionnaire. Results showed that there were distrust among members, members' distrust to WUAs mangers and tension in management of this organization. The most important solutions for farmer's participation in WUAs were to reduce local tensions, motivating mechanisms for cooperation of farmers in WUAs and helping farmers for a better consensus.

description: We use the time-independent quantum-mechanical formulation of reactive collisions in order to investigate the state-to-state $\mathrm{H}^+ + \mathrm{HD} \to \mathrm{D}^+ + \mathrm{H}_2$ chemical reaction. We compute cross sections for collision energies up to 1.8 electron-volts and rate coefficients for temperatures up to 10000 kelvin. We consider HD in the lowest vibrational level $v=0$ and rotational levels $j=0$ to 4, and H$_2$ in vibrational levels $v'=0$ to 3 and rotational levels $j'=0$ to 9. For temperatures below 4000 kelvin, the rate coefficients strongly vary with the initial rotational level $j$, depending on whether the reaction is endothermic ($j\le 2$) or exothermic ($j\ge 3$). The reaction is also found less and less probable as the final vibrational quantum number $v'$ increases. Our results illustrate the importance of studying state-to-state reactions, in the context of the chemistry of the primordial universe.

description: HST UV STIS imaging and spectroscopy of the low luminosity AGN (LLAGN) NGC 4303 have identified the previously detected UV-bright nucleus of this galaxy, as a compact, massive and luminous stellar cluster. The cluster with a size (FWHM) of 3.1 pc, and an ultraviolet luminosity log L (1500 A}(erg/s/A)= 38.33 is identified as a nuclear super star cluster (SSC) like those detected in the circumnuclear regions of spirals and starburst galaxies. The UV spectrum showing the characteristic broad P Cygni lines produced by the winds of massive young stars, is best fitted by the spectral energy distribution of a massive cluster of 1e5 Msol generated in an instantaneous burst 4 Myr ago. No evidence for an additional non-thermal ionizing source associated with an accreting black hole is detected in the ultraviolet. We hypothesize that at least some LLAGNs in spirals could be understood as the result of the combined ionizing radiation emitted by an evolving SSC and a black hole (BH) accreting with low radiative efficiency, coexisting in the inner few parsecs region.

description: This paper is devoted to a statistical analysis of the fluctuations of velocity and acceleration produced by a random distribution of point vortices in two-dimensional turbulence. We show that the velocity probability density function (p.d.f.) behaves in a manner which is intermediate between Gaussian and Lévy laws while the distribution of accelerations is governed by a Cauchy law. Our study accounts properly for a spectrum of circulations among the vortices. In the case of real vortices (with a finite core) we show analytically that the distribution of accelerations makes a smooth transition from Cauchy (for small fluctuations) to Gaussian (for large fluctuations) passing probably through an exponential tail. We introduce a function $T(V)$ which gives the typical duration of a velocity fluctuation $V$; we show that $T(V)$ behaves like $V$ and $V^{-1}$ for weak and large velocities respectively. These results have a simple physical interpretation in the nearest neighbor approximation and in Smoluchowski theory concerning the persistence of fluctuations. We discuss the analogies with respect to the fluctuations of the gravitational field in stellar systems. As an application of these results, we determine an approximate expression for the diffusion coefficient of point vortices. When applied to the context of freely decaying two-dimensional turbulence, the diffusion becomes anomalous and we establish a relationship $ν=1+{ξ\over 2}$ between the exponent of anomalous diffusion $ν$ and the exponent $ξ$ which characterizes the decay of the vortex density. This relation is in good agreement with laboratory experiments and numerical simulations.

description: We clarify the way in which cosmological perturbations of quantum origin, produced during inflation, assume classical properties. Two features play an important role in this process: First, the dynamics of fluctuations which are presently on large cosmological scales leads to a very peculiar state (highly squeezed) that is indistinguishable, in a precise sense, from a classical stochastic process. This holds for almost all initial quantum states. Second, the process of decoherence by interaction with the environment distinguishes the field amplitude basis as a robust pointer basis. We discuss in detail the interplay between these features and use simple analogies such as the free quantum particle to illustrate the main conceptual issues.

description: We present the result of a Chandra ACIS observation of the pulsar PSR B1853+01 and its associated pulsar wind nebula (PWN), embedded within the supernova remnant W44. A hard band ACIS map cleanly distinguishes the PWN from the thermal emission of W44. The nebula is extended in the north-south direction, with an extent about half that of the radio emission. Morphological differences between the X-ray and radio images are apparent. Spectral fitting reveals a clear difference in spectral index between the hard emission from PSR B1853+01 (Gamma ~ 1.4) and the extended nebula (Gamma ~ 2.2). The more accurate values for the X-ray flux and spectral index are used refine estimates for PWN parameters, including magnetic field strength, the average Lorentz factor, gamma, of the particles in the wind, the magnetization parameter, sigma, and the ratio k of electrons to other particles.

Random braking appears to be the symmetry-breaking field conjugate to the order parameter. For $v_{\max}=2$, we determine the values of the critical exponents $β$, $γ$ and $δ$ using an order-3 cluster approximation and computer simulations. These critical exponents satisfy a scaling relation, which can be derived assuming that the order parameter is a generalized homogeneous function of $|ρ-ρ_c|$ and p in the vicinity of the phase transition point.

description: A new method to measure the trilinear Higgs self-coupling $λ_3^{}$ in a single Higgs production process is proposed. Time-reversal-odd (T-odd) asymmetries in the process $e^+_{}e^-_{} \to ZH$, $Z \to f\bar{f}$ are computed from the absorptive part of the electroweak one-loop amplitude. Since the T-odd asymmetries measure the tree-level $t$-channel $ZH \to ZH$ scattering, they can be direct probes of $λ_3^{}$. The proposed method is quite challenging; a relatively large statistics and polarized $e^+_{}e^-_{}$ beams are demanded. However, this is probably the only approach to directly measure $λ_3^{}$ in $e^+_{}e^-_{}$ collisions, when a beam energy above the $ZHH$ production threshold is not available.

Our result is valid for arbitrary lengths L and $ΔL$. In the metallic limit the correlation function is given by a squared Lorentzian. In the localized regime it decays exponentially in both L and $ΔL$. The correlation length is proportional to L in the metallic regime and saturates at a value approximately given by the localization length $ξ$ as $L\ggξ$.

description: Um den Anforderungen zur Effizienzsteigerung und Umsetzung von Nachhaltigkeitsstrategien für Anwendungen im Hochtemperaturbereich gerecht zu werden, steigt die Notwendigkeit, das Eigenschaftsprofil der eingesetzten Konstruktionswerkstoffe weiter zu verbessern. Da typische, kommerziell eingesetzte Ni-Basis-Superlegierungen bereits aufgrund der Löslichkeitstemperatur der 𝛾‘ Verstärkungsphase an ihre Einsatzgrenze stoßen, ist die Entwicklung von neuen Hochtemperaturwerkstoffen für den Einsatz mit möglichen Oberflächentemperaturen oberhalb von 1100 °C unabdingbar. Die Legierungsentwicklung steht jedoch vor der Herausforderung, eine ausreichende Oxidationsbeständigkeit mit einer guten Kriechbeständigkeit zu kombinieren. In dieser Hinsicht erweisen sich Ti-makrolegierte Mo-Si-basierte Legierungen dank ihrer hohen Solidustemperatur im Bereich von 1800 °C und darüber bei deutlich geringeren Dichten von 6 bis 7 g/cm3 im Vergleich zu Ni-Basis-Superlegierungen als vielversprechend. Von Nachteil ist jedoch das katastrophale Oxidationsverhalten bei Temperaturen unterhalb von 1000 °C. Aufgrund der Bildung von flüchtigem MoO3 kommt es zu hohen Massenverlusten innerhalb kürzester Zeit. Dieses Phänomen wird als Pesting bezeichnet und ist bekannt dafür, bei reinem Molybdän und seinen Legierungen aufzutreten. In den neu entwickelten Mo-Si-Ti Legierungen kann dieses Pesting Verhalten jedoch unterbunden werden, wenn ein nomineller Ti-Gehalt von mindestens 40 bis 43 at% überschritten und gleichzeitig ein Si-Gehalt im Bereich von 20 bis 26 at% eingestellt wird. Diese Legierungen zeichnen sich durch feinstrukturierte eutektische bzw. eutektisch-eutektoide Gefüge aus. Das Eutektikum besteht aus Mo-Mischkristall MoSS und (Ti,Mo)5Si3, während die eutektoide Reaktion in MoSS und (Mo,Ti)5Si3 resultiert. Das Zusammenspiel aus dem Ti-reichen MoSS und den M5Si3 Silizidphasen ermöglicht die Bildung von Ti-Si-Oxidschichten, die die Abdampfung von MoO3 deutlich erschweren und starke Massenveränderungen verhindern. Bei hohen Temperaturen von 1200 °C liegt ebenfalls eine gute Oxidationsbeständigkeit vor. Das Verhältnis von Mo zu Ti ist jedoch nicht nur für die Oxidationsbeständigkeit ausschlaggebend, sondern auch für das Kriechverhalten, das stark mit der Solidustemperatur der Legierungen korreliert. Insofern führt die Maximierung des Mo-Gehaltes zur maximalen Ausnutzung des Kriechpotentials bei gleichzeitiger Einhaltung des notwendigen Ti-Gehaltes für Pesting Stabilität. Wird der Erstarrungsverlauf jedoch gezielt manipuliert, so dass (Mo,Ti)5Si3 als Verstärkungsphase primär erstarrt, so kann die Kriechbeständigkeit durch zusätzliche Erhöhung der Solidustemperatur, bei gleichzeitiger Beibehaltung der Pesting Stabilität, weiter verbessert werden.

description: The enormous sizes and variability of emission of radio-loud AGNs arise from the relativistic flows of plasma along two oppositely directed jets. We use the Athena hydrodynamics code to simulate an extensive suite of 54 propagating three-dimensional relativistic jets with wide ranges of input jet velocities and jet-to-ambient matter density ratios. We determine which parameter sets yield unstable jets that produce jet dominated FR I type radio galaxy morphologies and which tend to produce stable jets with hot-spots and FR II morphologies. Nearly all our simulations involve jets with internal pressures matched to those of the ambient medium but we also consider over-pressured jets and discuss differences from the standard ones. We also show that the results are not strongly dependent on the adiabatic index of the fluid. We focus on simulations that remain stable for extended distances (60-240) times the initial jet radius. Scaled to the much smaller sizes probed by VLBI observations, the fluctuations in such simulated flows yield variability in observed emissivity on timescales from months. Adopting results for the densities, pressures and velocities from these simulations we estimate normalized rest frame synchrotron emissivities from individual cells in the jets. The observed emission from each cell is strongly dependent upon its variable Doppler boosting factor. We sum the fluxes from thousands of zones around the primary reconfinement shock. The light curves an power-spectra, with red-noise slopes between -2.1 and -2.5, so produced are similar to those observed from blazars.

description: We investigate the copolymerization behavior of a two-component system into quasi-linear self-assemblies under conditions that interspecies binding is favored over identical species binding. The theoretical framework is based on a coarse-grained self-assembled Ising model with nearest neighbor interactions. In Ising language, such conditions correspond to the anti-ferromagnetic case giving rise to copolymers with predominantly alternating configurations. In the strong coupling limit, we show that the maximum fraction of polymerized material and the average length of strictly alternating copolymers depend on the stoichiometric ratio and the activation free energy of the more abundant species. They are substantially reduced when the stoichiometric ratio noticeably differs from unity. Moreover, for stoichiometric ratios close to unity, the copolymerization critical concentration is remarkably lower than the homopolymerization critical concentration of either species. We further analyze the polymerization behavior for a finite and negative coupling constant and characterize the composition of supramolecular copolymers. Our theoretical insights rationalize experimental results of supramolecular polymerization of oppositely charged monomeric species in aqueous solutions.

description: We study the Ramond twisted representations of the affine W-algebra W^k(g,f) in the case that f admits a good even grading. We establish the vanishing and the almost irreducibility of the corresponding BRST cohomology. This confirms some of the recent conjectures of Kac and Wakimoto. In type A, our results give the characters of all irreducible ordinary Ramond twisted representations of W^k(sl_n,f) for all nilpotent elements f and all non-critical k, and prove the existence of modular invariant representations conjectured by Kac and Wakimoto.

Holotype. Male USA: Connecticut: E. Norton (cited as “probably lost” by Cresson, 1916).
Notes: Bombus bimaculatus is one of the earliest bumble bee species to emerge in the spring in Connecticut and is found commonly throughout the state in many diverse environments such as sandplains, agricultural land, meadows, quarries, marsh, bogs, a coastal wildlife refuge, beach dunes, powerline ROW, and forests. The Connecticut type is evidently missing from ANSP and is presumed lost. It has been replaced with a male neotype from Massachusetts deposited at USNM (https://collections.nmnh.si.edu/search/ento/?ark=ark:/65665/ 35bb9c5e93a894307bed74ac350d6d3f3).

description: Crystal structure prediction with theoretical methods is particularly challenging when unit cells with many atoms need to be considered. Here we employ a symmetry-driven structure search (SYDSS) method and combine it with density functional theory (DFT) to predict novel crystal structures at high pressure. We sample randomly from all 1,506 Wyckoff positions of the 230 space groups to generate a set of initial structures. During the subsequent structural relaxation with DFT, existing symmetries are preserved, but the symmetries and the space group may change as atoms move to more symmetric positions. By construction, our algorithm generates symmetric structures with high probability without excluding any configurations. This improves the search efficiency, especially for large cells with 20 atoms or more. We apply our SYDSS algorithm to identify stoichiometric (H2O)_n-(NaCl)_m and C_nO_m compounds at high pressure. We predict a novel H2O-NaCl structure with Pnma symmetry to form at 3.4 Mbar, which is within the range of diamond anvil experiments. In addition, we predict a novel C2O structure at 19.8 Mbar and C4O structure at 44.0 Mbar with Pbca and C2/m symmetry respectively.
