description: As a test of rotationally-induced mixing causing the well-known Li dip in older mid-F dwarfs in the local Galactic disk, we utilize high-resolution and -S/N Keck/HIRESspectroscopy to measure the Li abundance in the components of the1 Gyr, [Fe/H]=-0.15 eclipsing short-period binary V505 Per. We find A(Li)=2.7+/-0.1 and 2.4+/-0.2 in the Teff=6500 and 6450 K primary and secondary components, respectively. Previous Teff determinations and uncertainties suggest that each component is located in the midst of the Li dip. If so, their A(Li) are >=2-5 times larger than A(Li) detections and upper limits observed in the similar metallicity and intermediate-age open clusters NGC 752 and 3680, as well as the more metal-rich and younger Hyades and Praesepe. These differences are even larger if the consistent estimates of the scaling ofinitial Li with metallicity inferred from nearby disk stars, open clusters, and recent Galactic chemical evolution models are correct. Our results suggest, independently of complementary evidence based on Li/Be ratios, Be/B ratios, and Li in subgiants evolving out of the Li dip, that main-sequence angular momentum evolution is the origin of the Li dip. Specifically, our stars' A(Li) indicates tidal synchronization can be sufficiently efficient and occur early enough in short-period binary mid-F stars to reduce the effects of rotationally-induced mixing and destruction of Li occuring during the main-sequence in otherwise similar stars that are not short-period tidally-locked binaries.

description: We study generation of two-dimensional dispersive shock waves and oblique dark solitons upon interaction of tilted plane waves with negative refractive index defects embedded into defocusing material with linear gain and two-photon absorption. Different evolution regimes are encountered including the formation of well-localized disturbances for input tilts below critical one, and generation of extended shock waves containing multiple intensity oscillations in the "upstream" region and gradually vanishing oblique dark solitons in "downstream" region for input tilts exceeding critical one. The generation of stable dispersive shock waves is possible only below certain critical defect strength.

Neutral defects in SrTiO3 studied with screened hybrid density functional theory

description: The properties of neutral defects in SrTiO3 are calculated using the screened hybrid density functional of Heyd, Scuseria, and Ernzerhof. The formation energies, the crystal field splittings affecting the SrTiO3 band structure, and the relaxation geometries around each defect are discussed. Oxygen vacancies introduced in SrTiO3 are found to cause a small tetragonal elongation of the lattice along the z-axis. The resulting conduction band minimum electron effective masses deviate from the bulk values and support the proposal of enhanced electron mobility along the direction of the compressive strain. The locations of the various defect bands within the SrTiO3 gap are estimated without introducing any post hoc corrections, thus allowing a more reliable comparison with experiment.

description: We investigate the interplay of Bloch oscillations and Anderson localization in optics. Gradual washing out of Bloch oscillations and the formation of nearly stationary averaged intensity distributions, which are symmetric for narrow and strongly asymmetric for broad input excitations, are observed experimentally in laser-written waveguide arrays. At large disorder levels Bloch oscillations are completely destroyed and both narrow and wide excitations lead to symmetric stationary averaged intensity distributions with exponentially decaying tails.

description: We present the results of detailed numerical study of a model for the sharing and sorting of informations in a community consisting of a large number of agents. The information gathering takes place in a sequence of mutual bipartite interactions where randomly selected pairs of agents communicate with each other to enhance their knowledge and sort out the common information. Though our model is less restricted compared to the well established naming game, yet the numerical results strongly indicate that the whole set of exponents characterizing this model are different from those of the naming game and they assume non-trivial values. Finally it appears that in analogy to the emergence of clusters in the phenomenon of percolation, one can define clusters of agents here having the same information. We have studied in detail the growth of the largest cluster in this article and performed its finite-size scaling analysis.

description: V. I. Arnold proved in 1991 (published in 1993) that the intersection multiplicity between two germs of analytic subvarieties at a fixed point of a holomorphic invertible self-map remains bounded when one of the germs is dragged by iterations of the self map. The proof is based on the Skolem-Mahler-Lech theorem on zeros in recurrent sequences. We give a different proof, based on the Noetherianity of certain algebras, which allows to generalize the Arnold's theorem for local actions of arbitrary finitely generated commutative groups, both with discrete and infinitesimal generators. Simple examples show that for non-commutative groups the analogous assertion fails.

Rossby Wave Instability with Self-Gravity

description: The Rossby wave instability (RWI) in non-self-gravitating discs can be triggered by a bump at a radius $r_0$ in the disc surface mass-density (which is proportional to the inverse potential vorticity). It gives rise to a growing non-axisymmetric perturbation [$\propto \exp(imϕ)$, $m=1,2..$] in the vicinity of $r_0$ consisting of anticyclonic vortices which may facilitate planetesimal growth in protoplanetary discs. Here, we analyze a continuum of thin disc models ranging from self-gravitating to non-selfgravitating. The key quantities determining the stability/instability are: (1) the parameters of the bump (or depression) in the disc surface density, (2) the Toomre $Q$ parameter of the disc (a non-self-gravitating disc has $Q\gg1$), and (3) the dimensionless azimuthal wavenumber of the perturbation $\bar{k}_ϕ=mQh/r_0$, where $h$ is the half-thickness of the disc. For discs stable to axisymmetric perturbations ($Q>1$), the self-gravity has a significant role for $\bar{k}_ϕ< π/2$ or $m π/2$ the self-gravity is not important, and instability may occur at a bump in the surface density. Thus, for all mode numbers $m \ge 1$, the self-gravity is unimportant for $Q > (π/2)(r_0/h)$. We suggest that the self-gravity be included in simulations for cases where $Q< (r_0/h)$.

description: Infinitesimals are natural products of the human imagination. Their history goes back to the Greek antiquity. Their role in the calculus and analysis has seen dramatic ups and downs. They have stimulated strong opinions and even vitriol. Edwin Hewitt developed hyperreal fields in the 1940s. Abraham Robinson's infinitesimals date from the 1960s. A noncommutative version of infinitesimals, due to Alain Connes, has been in use since the 1990s. We review some of the hyperreal concepts, and compare them with some of the concepts underlying noncommutative geometry.

description: Die vorliegende Arbeit beleuchtet die Rechtsmobilisierungshandlungen gewaltbetroffener Frauen in Hamburg und untersucht dabei insbesondere die Inanspruchnahme des Gewaltschutzgesetzes durch diese. Begleitet wird der Forschungsprozess von der sozialarbeiterischen Perspektive auf den Themenkomplex häusliche Gewalt und Rechtsmobilisierung. Geprägt ist das Vorgehen dieser Arbeit von selbst gemachten Praxiserfahrungen in der Frauenhausarbeit, aus der heraus das Ziel der praktischen Verbesserung der Lebensrealitäten sowohl für gewalt-betroffene als auch für alle in Hamburg lebenden Frauen erwächst. Praxis-, ergebnis- und lösungsorientiert wird die Fragestellung nach den Grundsätzen der Literaturarbeit bearbeitet, wobei nicht nur Literatur und Studien, sondern auch statistisches Rohmaterial aus dem Arbeitsfeld der Sozialen Arbeit analysiert, aufbereitet und miteinander in Verbindung gesetzt wird. Die Aufdeckung einer gravierenden Daten- und Wissenslücke, in Verbindung mit der Feststellung konkreten Handlungsbedarfs bei der Schaffung automatisierter Netzwerkstrukturen, Vereinfachung der Inanspruchnahme des Gewaltschutzgesetzes, und Verbesserung der gesetzlichen Rahmenbedingungen, gehören dabei zu den Kernergebnissen vorliegender Arbeit. Die Überführung ausgearbeiteter Ergebnisse in einen Maßnahmenkatalog mit Handlungsempfehlungen, gerichtet an die Verantwortlichen der Stadt Hamburg, liefert dann konkrete Grundlagen zur Initiierung von Maßnahmen und im Weiteren auch Impulse für eine empirische Anschluss-forschung. Auch über die gestellte Forschungsfrage hinaus liefert die Beschäftigung mit dem Thema viel Potenzial für eine fruchtbare Gestaltung zukünftiger Lebensrealitäten von Frauen in Hamburg und ganz Deutschland.

description: We measured the cross-correlation of the Wilkinson Microwave Anisotropy Probe (WMAP) 7 year temperature map and the full sky data release of the Wide-field Infrared Survey Explorer (WISE) galaxy map. Using careful mapmaking and masking techniques we find a positive cross-correlation signal. The results are fully consistent with a Lambda-CDM Universe, although not statistically significant. Our findings are robust against changing the galactic latitude cut from |b|>10 to |b|>20 and no color dependence was detected when we used WMAP Q, V or W maps. We confirm higher significance correlations found in the preliminary data release. The change in significance is consistent with cosmic variance.

description: Overwhelming diversity of long gamma-ray bursts (LGRBs), discovered after the launch of {\it Swift} satellite, is a major obstacle to LGRB studies. Recently, it is shown that the prompt emission of LGRBs is classified into three subclasses: Type I, Type II LGRBs populating separate fundamental planes in a 3D space defined by the peak luminosity, the duration, and the spectral peak energy, and outliers not belonging to either of the planes. Here we show that Type I LGRBs (LGRBs I) exhibit different shapes of light curves from Type II LGRBs (LGRBs II). Furthermore, we demonstrate that this classification has uncovered a new scaling law in the light curves of LGRBs II spanning 8 orders of magnitude from the prompt to late X-ray afterglow emission. The scaled light curve has four distinct phases. The first phase has a characteristic time scale while the subsequent three phases exhibit power law behaviors with different exponents. We discuss its possible interpretation in terms of the emission from an optically thick fireball propagating in the cricumstellar matter at relativistic speeds and argue that the observed four phases correspond to its hydrodynamical phases. Our classification scheme can pin down the intrinsic luminosities of LGRBs II through the scaling law from a sample of polymorphic GRBs. Further refinement of this scheme and scaling law will make a subclass of LGRBs a standard candle as reliable and accurate as Type Ia supernovae in the more distant universe than supernovae can reach.

description: Tensor solutions ($r$-matrices) of the classical Yang-Baxter equation (CYBE) in a Lie algebra, obtained as the classical limit of the $R$-matrix solution of the quantum Yang-Baxter equation (QYBE), is an important structure appearing in different areas such as integrable systems, symplectic geometry, quantum groups and quantum field theory. Further study of CYBE led to its interpretation as certain operators, giving rise to the concept of O-operators. In [3], the O-operators were in turn interpreted as tensor solutions of CYBE by enlarging the Lie algebra. The purpose of this paper is to extend this study to a more general class of operators that were recently introduced [4] in the study of Lax pairs in integrable systems. Relationship between $\calo$-operators, relative differential operators and Rota-Baxter operators are also discussed.

description: The theory of the inverse problem is used in order to find a two dimensional galactic potential generating a mono-parametric family of elliptic periodic orbits. The potential is made up of a two-dimensional harmonic oscillator with perturbing terms of third and fourth degree and can be considered to describe local motion in the central parts of a barred galaxy. Our numerical calculations indicate that the potential produces also other families of orbits and there are cases, where distinct chaotic components are also observed. The numerical experiments suggest that there are regular as well as chaotic orbits supporting the barred structure. We use a variety of dynamical indicators, in order to determine the character of motion. Of significant interest, is the S(g) dynamical spectrum, which is used in order to identify the islandic motion of resonant orbits and also proves to be a very useful and fast indicator, in order to distinguish between regular and chaotic motion. Comparison with other methods for detecting chaos is also discussed. The present results are compared with outcomes from earlier work.

We show that this class of fractions has a natural structure of shuffle algebra. This finding conceptualizes the connections among the various methods of stuffle, shuffle and partial fractions in the study of MZVs. This approach also gives an explicit product formula of the fractions.

description: Here we calculate the dynamic susceptibility and dynamic correlation function in spin ice using the model of emergent magnetic monopoles. Calculations are based on a method originally suggested for the description of dynamic processes in water ice (non-equilibrium thermodynamics approach). We show that for zero temperature the dynamic correlation function reproduces the transverse dipole correlations (static correlation function) characteristic of spin ice in its ground state. At non-zero temperatures the dynamic correlation function includes an additional longitudinal component which decreases as the temperature decreases. Both terms (transverse and longitudinal) exhibit identical Debye-like dependences on frequency but with different relaxation times: the magnetic Coulomb interaction of monopoles reduces the longitudinal relaxation time with respect to the transverse one. We calculate the dielectric function for the magnetic monopole gas and discuss how the non-equilibrium thermodynamics approach exposes corrections to the Debye-Huckel theory of magnetic monopoles and the concept of "entropic charge".

A positivity-preserving scheme for the simulation of streamer discharges in non-attaching and attaching gases
Creators: name: Zhuang, Chijie

subject: FOS: Physical sciences

description: Assumed having axial symmetry, the streamer discharge is often described by a fluid model in cylindrical coordinate system, which consists of convection dominated (diffusion) equations with source terms, coupled with a Poisson's equation. Without additional care for a stricter CFL condition or special treatment to the negative source term, popular methods used in streamer discharge simulations, e.g., FEM-FCT, FVM, cannot ensure the positivity of the particle densities for the cases in attaching gases. By introducing the positivity-preserving limiter proposed by Zhang and Shu \cite{ppl} and Strang operator splitting, this paper proposed a finite difference scheme with a provable positivity-preserving property in cylindrical coordinate system, for the numerical simulation of streamer discharges in non-attaching and attaching gases. Numerical examples in non-attaching gas (N$_2$) and attaching gas (SF$_6$) are given to illustrate the effectiveness of the scheme.

description: The motion in a simple, time independent rational galactic potential is studied. The potential is a generalization of a two dimensional harmonic oscillator potential and can be considered to describe plane motion in the central parts of a galaxy. There are cases, where the potential displays accurate periodic orbits, together with large chaotic regions. The starting position of these orbits can be found using analytical arguments. Using a quasi-integral of motion, we study the stability of the central periodic orbit and explain the degree of chaos in the inner regions of the galaxy. Our outcomes are compared with results coming from polynomial potentials with accurate periodic orbits and large chaotic regions.

The Relationship Between X-ray Luminosity and Major Flare Launching in GRS 1915+105

description: We perform the most detailed analysis to date of the X-ray state of the Galactic black hole candidate GRS 1915+105 just prior to (0 to 4 hours) and during the brief (1 to 7 hour) ejection of major (superluminal) radio flares. A very strong model independent correlation is found between the 1.2 keV - 12 keV X-ray flux 0 to 4 hours before flare ejections with the peak optically thin 2.3 GHz emission of the flares. This suggests a direct physical connection between the energy in the ejection and the luminosity of the accretion flow preceding the ejection. In order to quantify this concept, we develop techniques to estimate the intrinsic (unabsorbed) X-ray luminosity, $L_{\mathrm{intrinsic}}$, from RXTE ASM data and to implement known methods to estimate the time averaged power required to launch the radio emitting plasmoids, $Q$ (sometimes called jet power). We find that the distribution of intrinsic luminosity from 1.2 keV - 50 keV, $L_{\mathrm{intrinsic}}(1.2 - 50)$, is systematically elevated just before ejections compared to arbitrary times when there are no major ejections. The estimated $Q$ is strongly correlated with $L_{\mathrm{intrinsic}}(1.2 - 50)$ 0 to 4 hours before the ejection, the increase in $L_{\mathrm{intrinsic}}(1.2 - 50)$ in the hours preceding the ejection and the time averaged $L_{\mathrm{intrinsic}}(1.2 - 50)$ during the flare rise. Furthermore, the total time averaged power during the ejection ($Q$ + the time average of $L_{\mathrm{intrinsic}}(1.2 - 50)$ during ejection) is strongly correlated with $L_{\mathrm{intrinsic}}(1.2 - 50)$ just before launch with near equality if the distance to the source is $ \approx 10.5$ kpc.

description: We report the operation of a dual Rb/Cs atomic fountain clock. 133Cs and 87Rb atoms are cooled, launched, and detected simultaneously in LNE-SYRTE's FO2 double fountain. The dual clock operation occurs with no degradation of either the stability or the accuracy. We describe the key features for achieving such a simultaneous operation. We also report on the results of the first Rb/Cs frequency measurement campaign performed with FO2 in this dual atom clock configuration, including a new determination of the absolute 87Rb hyperfine frequency.

Revisiting conserved currents in F(R) theory of gravity via Noether symmetry

description: Noether symmetry of F(R) theory of gravity in vacuum and in the presence of pressureless dust yields F(R) \propto R^{3/2} along with the conserved current \frac{d}{dt}(a\sqrt R) in Robertson-Walker metric and nothing else. Still some authors recently claimed to have obtained four conserved currents setting F(R) \propto R^{3/2} a-priori, taking time translation along with a gauge term. We show that the first one of these does not satisfy the field equations and the second one is the Hamiltonian which is constrained to vanish in gravity and thus a part and parcel of the field equations. We also show that the other two conserved currents, which do not contain time translation are the same in disguise and identical to the one mentioned above. Thus the claim is wrong.

Non-specular reflections in a macroscopic system with wave-particle duality: spiral waves in bounded media

Year: 2013
Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: Spiral waves in excitable media possess both wave-like and particle-like properties. When resonantly forced (forced at the spiral rotation frequency) spiral cores travel along straight trajectories, but may reflect from medium boundaries. Here, numerical simulations are used to study reflections from two types of boundaries. The first is a no-flux boundary which waves cannot cross, while the second is a step change in the medium excitability which waves do cross. Both small-core and large-core spirals are investigated. The predominant feature in all cases is that the reflected angle varies very little with incident angle for large ranges of incident angles. Comparisons are made to the theory of Biktashev and Holden. Large-core spirals exhibit other phenomena such as binding to boundaries. The dynamics of multiple reflections is briefly considered.

title: An Ethnographic Study Of Modernisation in Practice
titleType: Subtitle
Creators: name: Green, Richard
Publisher: name: Lancaster University
Year: 2023

description: The thesis is formed of an ethnographic study of public law practice in a family court in England, with reference to reforms of family justice (commonly referred to as ‘modernisation’). It draws on Complexity Theory to analyse policy and practice. Direct observation of public law work, supplemented by professional interviews, facilitates close engagement with practice and thereby adds to the meagre ethnographic literature on family justice. The thesis examines the influence of rational thinking upon modernisation (characterised by a statutory timeframe for care proceedings and curbs on the court’s power to appoint expert witnesses), the short-term benefits and longer-term problems that have flowed from rational policymaking, and the ways professionals in the family court try to deliver fair justice and support children’s welfare despite modernisation, which many now consider problematic. The relationship between policymaking and practice is explored, including the ways that professionals interpret the law and thus make policy upstream. The complexities of public law work are uncovered: the commonly intractable social and health problems of families subject to care applications; a family justice system that is formally adversarial in nature but also incorporates elements of consensual justice; challenges to managing cases that do not neatly fit into the prescriptions of modernisation; and, finally, the impact of Covid-19. The thesis advocates a more responsive and pragmatic policymaking to acknowledge the role played by professionals in making policy and to enable family justice to recover from the pandemic. It also argues that expectations that the family court can resolve many families’ complex problems are unrealistic and makes the case for more concerted efforts to support families before and after proceedings.

description: In the article is represented an analysis of the different areas of using virtual reality technologies (VR) in medicine in the Russian Federation. Virtual reality gives a chance for creating multi-tiered systems such as VR-based operating rooms. VR allows organizing the medical operations with a high accuracy of steering. VR technology is also used in the education process of young doctors. Most often VR is known to be an auxiliary method in such areas as neurorehabilitation. More than that, VR can influence re-storing of body movements after lessons. In the conclusion it is stressed that VR technologies need to be studied and made a detailed description.
