description: In quantum field theory it is believed that the spontaneous decay of excited atomic or molecular level is due to the interaction with continuum of field modes. Besides, the atom makes a transition from upper level to lower one so that the probability to find the atom in the excited state tends to zero. In this paper it will be shown that the mathematical model in single-photon approximation may predict another behavior of this probability generally. Namely, the probability to find the atom in the excited state may tend to a nonzero constant so that the atom is not in the pure state finally. This effect is due to that the spectrum of the complete hamiltonian is not purely absolutely continuous and has a discrete level outside the continuous part. Namely, we state that in the corresponding invariant subspace, determining the time evolution, the spectrum of the complete hamiltonian when the field is considered in three dimensions may be not purely absolutely continuous and may have an eigenvalue. The appearance of eigenvalue has a threshold character. If the field is considered in two dimensions the spectrum always has an eigenvalue and the decay is absent.

New Methods for Extracting the CKM Angle $γ$ using $B^\pm\to D^0 K^-$; $\bar D^0 K^-$

description: In this talk I will discuss the extraction of the CKM angle $γ$ at B-factories through the interference of the subprocesses $B^-\to K^- D^0$ and $B^- \to K^-\bar D^0$. This seemingly impossible interference may be accomplished by allowing both $D^0$ and $\bar D^0$ to decay to a common final state. If only CP eigenstate decay modes of the $D$ are considered, the branching ratio for $B^- \to \bar D^0 K^-$ must be experimentally I describe why this determination is likely to be experimentally impossible. On the other hand, if more general $D$ decays are considered, the angle $γ$ may then be determined. In fact, it is possible that a reasonable determination of $γ$ may be made with O(10^8) B's.

description: Gaia DR2 provides an unprecedented sample of stars with full 6D phase-space measurements, creating the need for a self-consistent means of discovering and characterising the phase-space overdensities known as moving groups or associations. Here we present Chronostar, a new Bayesian analysis tool that meets this need. Chronostar uses the Expectation-Maximisation algorithm to remove the circular dependency between association membership lists and fits to their phase-space distributions, making it possible to discover unknown associations within a kinematic data set. It uses forward-modelling of orbits through the Galactic potential to overcome the problem of tracing backward stars whose kinematics have significant observational errors, thereby providing reliable ages. In tests using synthetic data sets with realistic measurement errors and complex initial distributions, Chronostar successfully recovers membership assignments and kinematic ages up to ~ 100 Myr. In tests on real stellar kinematic data in the phase-space vicinity of the $β$ Pictoris Moving Group, Chronostar successfully rediscovers the association without any human intervention, identifies 15 new likely members, corroborates 43 candidate members, and returns a kinematic age of 17.8+-1.2 Myr. In the process we also rediscover the Tucana-Horologium Moving Group, for which we obtain a kinematic age of 36.3+1.3-1.4 Myr.

description: Datasets advance research by posing challenging new problems and providing standardized methods of algorithm comparison. High-quality datasets exist for many important problems in robotics and computer vision, including egomotion estimation and motion/scene segmentation, but not for techniques that estimate every motion in a scene. Metric evaluation of these multimotion estimation techniques requires datasets consisting of multiple, complex motions that also contain ground truth for every moving body. The Oxford Multimotion Dataset provides a number of multimotion estimation problems of varying complexity. It includes both complex problems that challenge existing algorithms as well as a number of simpler problems to support development. These include observations from both static and dynamic sensors, a varying number of moving bodies, and a variety of different 3D motions. It also provides a number of experiments designed to isolate specific challenges of the multimotion problem, including rotation about the optical axis and occlusion. In total, the Oxford Multimotion Dataset contains over 110 minutes of multimotion data consisting of stereo and RGB-D camera images, IMU data, and Vicon ground-truth trajectories. The dataset culminates in a complex toy car segment representative of many challenging real-world scenarios. This paper describes each experiment with a focus on its relevance to the multimotion estimation problem.

Second-order cosmological perturbations. III. Produced by scalar-scalar coupling during radiation-dominated stage

Year: 2018
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We study the 2nd-order scalar, vector and tensor metric perturbations in Robertson-Walker (RW) spacetime in synchronous coordinates during the radiation dominated (RD) stage. The dominant radiation is modeled by a relativistic fluid described by a stress tensor $T_{μν}=(ρ+p)U_μU_ν+g_{μν}p$ with $p= c^2_s ρ$, and the 1st-order velocity is assumed to be curlless. We analyze the solutions of 1st-order perturbations, upon which the solutions of 2nd-order perturbation are based. We show that the 1st-order tensor modes propagate at the speed of light and are truly radiative, but the scalar and vector modes do not. The 2nd-order perturbed Einstein equation contains various couplings of 1st-order metric perturbations, and the scalar-scalar coupling is considered in this paper. We decompose the 2nd-order Einstein equation into the evolution equations of 2nd-order scalar, vector, and tensor perturbations, and the energy and momentum constraints. The coupling terms and the stress tensor of the fluid together serve as the effective source for the 2nd-order metric perturbations. The equation of covariant conservation of stress tensor is also needed to determine $ρ$ and $U^μ$. By solving this set of equations up to 2nd order analytically, we obtain the 2nd-order integral solutions of all the metric perturbations, density contrast and velocity. To use these solutions in applications, one needs to carry out seven types of the numerical integrals. We perform the residual gauge transformations between synchronous coordinates up to 2nd order, and identify the gauge-invariant modes of 2nd-order solutions.

description: We make a semiclassical analysis of thermal pair creations of quasiparticles at various filling factors in quantum Hall systems. It is argued that the gap energy is reduced considerably by the Coulomb potential made by impurities. It is also shown that a tunneling process becomes important at low temperature and at strong magnetic field. We fit typical experimental data excellently based on our semiclassical results of the gap energy.

description: Numerical attoclock is a theoretical model of attosecond angular streaking driven by a very short, nearly a single oscillation, circularly polarized laser pulse. The reading of such an attoclock is readily obtained from a numerical solution of the time-dependent Schrödinger equation as well as a semi-classical trajectory simulation. By making comparison of the two approaches, we highlight the essential physics behind the attoclock measurements. In addition, we analyze the predictions of the Keldysh-Rutherford model of the attoclock [Phys. Rev. Lett. 121, 123201 (2018)]. In molecular hydrogen, we highlight a strong dependence of the width of the attoclock angular peak on the molecular orientation and attribute it to the two-center electron interference. This effect is further exemplified in the weakly bound neon dimer.

description: We address the problem of finding the optimal common resource for an arbitrary family of target states in quantum resource theories based on majorization, that is, theories whose conversion law between resources is determined by a majorization relationship, such as it happens with entanglement, coherence or purity. We provide a conclusive answer to this problem by appealing to the completeness property of the majorization lattice. We give a proof of this property that relies heavily on the more geometric construction provided by the Lorenz curves, which allows to explicitly obtain the corresponding infimum and supremum. Our framework includes the case of possibly non-denumerable sets of target states (i.e. targets sets described by continuous parameters). In addition, we show that a notion of approximate majorization, which has recently found application in quantum thermodynamics, is in close relation with the completeness of this lattice. Finally, we provide some examples of optimal common resources within the resource theory of quantum coherence.

description: Effects of electron correlation in FeSi are studied in terms of the two-band Hubbard model with the density of states obtained from the band calculation. Using the self-consistent second-order perturbation theory combined with the local approximation, the correlation effects are investigated on the density of states and the optical conductivity spectrum, which are found to reproduce the experiments done by Damascelli et al. semiquantitatively. It is also found that the peak at the gap edge shifts to lower energy region by correlation effects, as is seen in the experiments.

Two-Loop Large-$m_t$ Electroweak Corrections to $K\toπν\barν$ for Arbitrary Higgs Boson Mass

Year: 1997

description: We consider for the first time the leading large top mass corrections, arising at higher order in electroweak interactions, to the rare decays $K\toπν\barν$ and the related modes $B\to X_sν\barν$ and $B\to l^+l^-$. Higher order effects of similar type have previously been calculated in the large-$m_t$ limit for key observables of precision electroweak physics at Z-factories. Here we obtain the corresponding corrections of order ${\cal O}(G^2_F m^4_t)$ at the amplitude level for short-distance dominated rare meson decays. This allows us to quantify the importance of higher order electroweak effects for these processes, which can be reliably computed and have very small uncertainties from strong interactions. Simultaneously it becomes possible to remove, to some extent, ambiguities in the definition of electroweak parameters describing the strength of FCNC interactions. The corrections we discuss are at the level of a few percent.

Workplace violence: a policy analysis
Creators: name: Formanes, Lorraine R.
Publisher: name: No Publisher Supplied
Year: 2021

description: BACKGROUND: Workplace violence (WPV) against healthcare workers is a topic that has gained increased recognition over the past several years. WPV results in decreased job satisfaction, increased absenteeism, and high job turnover. All of these factors ultimately affect patient care and are associated with increased healthcare costs. Limited centralized resources exist for healthcare organizations seeking to develop WPV policies.PURPOSE: The purpose of this Doctor of Nursing Practice Project was to: 1) establish a repository of WPV policies to serve as a resource for healthcare organizations seeking to develop WPV policies; and 2) identify best practices for developing a WPV policy at a major academic ambulatory medical center.METHODS: Using a web-based search, ambulatory healthcare facilities in the state of New Jersey were identified. A survey focusing on current WPV practices was distributed and completed by these organizations. RESULTS/FINDINGS: A total of 35 surveys were completed. The majority of ambulatory facilities that are associated with larger hospital systems do not have a separate policy for their ambulatory clinics. There was a lack of consistency among respondents as to which department was responsible for oversight of the WPV policies within an organization. Few organizations had an employee bill of rights ensuring a workplace that is safe and free from violence.CONCLUSIONS/IMPLICATIONS: Effective and thorough WPV policies encourage a healthy work culture. Organizations considering the development of a WPV policy should consider establishment of a facility WPV task force and WPV education protocol. An integral part of organizational policy. Future exploration of WPV policies and procedures for ambulatory healthcare facilities are needed.

Localizations of infinite subsets of omega

Publisher: name: arXiv
Year: 1995
Subjects: subject: Logic (math.LO)

description: In the present paper we are interested in properties of forcing notions which measure in a sense the distance between the ground model reals and the reals in the extension. We look at the ways the ``new'' reals can be aproximated by ``old'' reals. We consider localizations for infinite subsets of omega. Though each member of [omega]^omega can be identified with its increasing enumeration, the (standard) localizations of the enumeration does not provide satisfactory information on successive points of the set. They give us ``candidates'' for the n-th point of the set but the same candidates can appear several times for distinct n. That led to a suggestion that we should consider disjoint subsets of omega as sets of ``candidates'' for successive points of the localized set. We have two possibilities. Either we can demand that each set from the localization contains a limited number of members of the localized set or we can postulate that each intersection of that kind is large. Localizations of this kind are studied in section 1. In the second section we investigate localizations of infinite subsets of omega by sets of integers from the ground model. These localizations might be thought as localizations by partitions of omega into successive intervals.

Macroscopic Quantum Tunneling of a Fluxon in a Long Josephson Junction

Publisher: name: arXiv
Year: 1996
Subjects: subject: Condensed Matter (cond-mat)

description: Macroscopic quantum tunneling (MQT) for a single fluxon moving along a long Josephson junction is studied theoretically. To introduce a fluxon-pinning force, we consider inhomogeneities made by modifying thickness of an insulating layer locally. Two different situations are studied: one is the quantum tunneling from a metastable state caused by a single inhomogeneity, and the other is the quantum tunneling in a two-state system made by two inhomogeneities. In the quantum tunneling from a metastable state, the decay rate is estimated within the WKB approximation. Dissipation effects on a fluxon dynamics are taken into account by the Caldeira-Leggett theory. We propose a device to observe quantum tunneling of a fluxon experimentally. Required experimental resolutions to observe MQT of a fluxon seem attainable within the presently available micro-fabrication technique. For the two-state system, we study quantum resonance between two stable states, i.e., macroscopic quantum coherence (MQC). From the estimate for dissipation coefficients due to quasiparticle tunneling, the observation of MQC appears to be possible within the Caldeira-Leggett theory.

description: Localized states are a universal phenomenon observed in spatially distributed dissipative nonlinear systems. Known as dissipative solitons, auto-solitons, spot or pulse solutions, these states play an important role in data transmission using optical pulses, neural signal propagation, and other processes. While this phenomenon was thoroughly studied in spatially extended systems, temporally localized states are gaining attention only recently, driven primarily by applications from fiber or semiconductor lasers. Here we present a theory for temporal dissipative solitons (TDS) in systems with time-delayed feedback. In particular, we derive a system with an advanced argument, which determines the profile of the TDS. We also provide a complete classification of the spectrum of TDS into interface and pseudo-continuous spectrum. We illustrate our theory with two examples: a generic delayed phase oscillator, which is a reduced model for an injected laser with feedback, and the FitzHugh-Nagumo neuron with delayed feedback. Finally, we discuss possible destabilization mechanisms of TDS and show an example where the TDS delocalizes and its pseudo-continuous spectrum develops a modulational instability.

description: Lagrangian data assimilation is a complex problem in oceanic and atmospheric modeling. Tracking drifters in large-scale geophysical flows can involve uncertainty in drifter location, complex inertial effects, and other factors which make comparing them to simulated Lagrangian trajectories from numerical models extremely challenging. Temporal and spatial discretization, factors necessary in modeling large scale flows, also contribute to separation between real and simulated drifter trajectories. The chaotic advection inherent in these turbulent flows tends to separate even closely spaced tracer particles, making error metrics based solely on drifter displacements unsuitable for estimating model parameters. We propose to instead use error in the coherent structure coloring (CSC) field to assess model skill. The CSC field provides a spatial representation of the underlying coherent patterns in the flow, and we show that it is a more robust metric for assessing model accuracy. Through the use of two test cases, one considering spatial uncertainty in particle initialization, and one examining the influence of stochastic error along a trajectory and temporal discretization, we show that error in the coherent structure coloring field can be used to accurately determine single or multiple simultaneously unknown model parameters, whereas a conventional error metric based on error in drifter displacement fails. Because the CSC field enhances the difference in error between correct and incorrect model parameters, error minima in model parameter sweeps become more distinct. The effectiveness and robustness of this method for single and multi-parameter estimation in analytical flows suggests that Lagrangian data assimilation for real oceanic and atmospheric models would benefit from a similar approach.

description: The first interstellar object, `Oumuamua, was discovered in the Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance of interstellar objects of its size and an estimation of the subset of objects trapped by the Jupiter-Sun system. Photographing or visiting these trapped objects would allow for learning about the conditions in other planetary systems, saving the need to send interstellar probes. Here, we explore the orbital properties of captured interstellar objects in the Solar System using dynamical simulations of the Jupiter-Sun system and initial conditions drawn from the distribution of relative velocities of stars in the Solar neighborhood. We compare the resulting distributions of orbital elements to those of the most similar population of known asteroids, namely Centaurs, to search for a parameter space in which interstellar objects should dominate and therefore be identifiable solely by their orbits. We find that there should be thousands of `Oumuamua-size interstellar objects identifiable by Centaur-like orbits at high inclinations, assuming a number density of `Oumuamua-size interstellar objects of $\sim 10^{15} \; \mathrm{pc^{-3}}$. We note eight known objects that may be of interstellar origin. Finally, we estimate that LSST will be able to detect several hundreds of these objects.

description: We present a coherent scenario for the physics of cuprate superconductors, which is based on a charge-driven inhomogeneity, i.e. the ``stripe phase''. We show that spin and charge critical fluctuations near the stripe instability of strongly correlated electron systems provide an effective interaction between the quasiparticles, which is strongly momentum, frequency, temperature and doping dependent. This accounts for the various phenomena occurring in the overdoped, optimally and underdoped regimes both for the normal and the superconductive phase.

description: This chapter investigates actions for annulment. Annulment actions constitute a central yet by-and-large neglected device of judicial review in the European Union. We focus on cases in which member states take the European Commission to the Court of Justice of the European Union in order to fend off interferences with domestic policy application. Specifically, we ask when and why member states initiate such actions for annulment. To assess the validity of different answers to this question, we use data on the frequency of annulment litigation and evaluate the impact of four potential explanatory factors: the creative agency of the supervising Commission, the inept application of EU law by a shirking agent government, the heterogeneity of preferences held by the collective principal (i.e., the Council), and the interruption of the relationship between the commission and member state governments.
description: Gegenstand der Analyse in diesem Kapitel sind Nichtigkeitsklagen vor dem Europäischen Gerichtshof. Nichtigkeitsklagen sind eine zentrale, aber bisher weitgehend unerforschte Kategorie der Normenkontrolle im EU System. Wir untersuchen solche Klagefälle, in denen Mitgliedstaaten, um Eingriffe in nationale Politikgestaltung abzuwehren, die Europäische Kommission vor dem Europäischen Gerichtshof verklagen. Wann und warum entscheiden sich nationale Regierungen für eine solche Nichtigkeitsklage? Um diese Frage zu beantworten werden vier potentielle Erklärungsfaktoren mit Hilfe von quantitativen Daten zur Häufigkeit der Klageerhebung in der EU-15 getestet: kreatives Handeln der Kommission als Agentin, unangemessene Anwendung durch eine pflichtverletzende nationale Regierung, heterogene Präferenzen im Rat als kollektivem Prinzipal und die Unterbrechung der Beziehung zwischen Kommission und mitgliedstaatlicher Regierung, z.B. durch Wahlen oder die Benennung eines neuen Kommissars

description: We investigate an important radiative correction to the slepton and chargino production processes. We consider a supersymmetric spectrum with a large splitting between the squark and slepton masses. In this case, in the effective theory below the squark mass threshold, the supersymmetric Slavnov-Taylor identities which enforce the equality of the gauge and gaugino couplings are violated. The gaugino propagators receive potentially large corrections due to virtual quark/squark loop effects. We compute the full one-loop (s)quark corrected slepton production cross-sections. The t-channel one-loop scattering amplitudes are factorized into an effective chargino/neutralino mass matrix and an effective fermion-sfermion-gaugino coupling. The difference between the effective gaugino coupling and the gauge coupling is proportional to log(Msq/msl) in the large squark mass limit. We find that the one-loop corrected slepton production cross-sections can depend on the squark mass strongly, up to 9% times log(Msq/msl). We investigate the squark mass sensitivity of the slepton cross-section measurements at a future linear collider. For sneutrino production accessible at sqrt{s}= 500 GeV there can be sensitivity to squark masses at or larger than 1 TeV.

description: Transport of intensity equation (TIE) has been applied to process the simulated and experimental images of the magnetic hard nanobubbles, which were acquired in the Lorentz transmission electron microscope (LTEM). Systematic studies demonstrated that the processing parameter in TIE can modulate the features of the retrieved magnetization and induce the bi-spiral structures which may be identified as the bi-skyrmions.

description: Diese Arbeit untersucht einen Teil der komplexen Thematik von Migration und Integration, die einen zentralen Stellenwert in den globalen politischen und gesellschaftlichen Debatten einnimmt. Integration wird dabei als multidimensionaler Prozess verstanden, der über die rein rechtliche Anerkennung hinausgeht und Fragen der Identitätskonstruktion und sozialen Positionierung aufwirft. Im Fokus steht die Analyse des Einflusses öffentlicher Diskurse auf die narrative Selbstdarstellung von Migrant:innen. Theoretisch fundiert sich die Untersuchung auf die narrative Analyse und die „Positioning“-Theorie (v.a. basierend auf Michael Bamberg), die Aufschluss darüber gibt, wie Migrant:innen sich und andere in sozialen Kontexten positionieren. Der empirische Teil stützt sich auf Interviews mit kubanischen Geflüchteten, die im Rahmen des VIOLIN-Projekts ("Verbal Violence against Migrants in Institutions") – einer Untersuchung (v.a. versteckter Formen von) verbaler Gewalt in institutionellen Kontexten – durchgeführt wurden. Ziel der Analyse ist es, zu verstehen, wie öffentliche Diskurse die Selbstwahrnehmung und Integration von Migrant:innen prägen und welche Rolle dabei Konzepte wie die „enregistered identities“ (nach Anna de Fina) von „good“ und „bad migrants“ spielen.
description: Este trabajo examina un aspecto de la compleja temática de la migración y la integración, que ocupa un lugar central en los debates políticos y sociales a nivel global. La integración se entiende aquí como un proceso multidimensional que trasciende el reconocimiento legal, abordando cuestiones de construcción identitaria y posicionamiento social. El foco de este análisis está en el impacto de los discursos públicos sobre la autopresentación narrativa de las personas migrantes. Teóricamente, el estudio se basa en el análisis narrativo y en la teoría del "positioning" (particularmente fundamentada en los trabajos de Michael Bamberg), que permite comprender cómo las personas migrantes se posicionan a sí mismas y a los demás en contextos sociales. La parte empírica se apoya en entrevistas realizadas a refugiados cubanos en el marco del proyecto VIOLIN (Verbal Violence against Migrants in Institutions), una investigación centrada en formas (en particular ocultas) de violencia verbal en contextos institucionales. El objetivo del análisis es entender cómo los discursos públicos moldean la autopercepción y la integración de las personas migrantes, y cuál es el rol de conceptos como las "enregistered identities" (según Anna de Fina) de "good" y "bad migrants" en este proceso.
Power shifts via the judicial arena: how annulments cases between EU institutions shape competence allocation

description: Besides infringement and preliminary ruling procedures, actions for annulment form a third important category of procedures brought before the Court of Justice of the European Union (CJEU). A subset of these actions is ‘horizontal litigation’, where EU institutions litigate against other EU institutions. Based on a new dataset covering all horizontal annulment conflicts (1957–2017), this contribution analyzes conflict patterns. I identify the most typical litigant constellations and link them to substantial battles over competences including winners and losers. Using the example of EU external affairs, I show how annulment actions have shaped the relationship between EU institutions over time, with impact as significant as treaty changes. In sum, the analysis of this so far ‘forgotten’ type of procedure furthers our systematic understanding of policy development and competence allocation in the EU system.

description: Dispersion relations and polarizations for surface waves in infinite planar samples in the QHE regime are explicitly determined in the small wavevector limit in which the dielectric tensor can be considered as local. The wavelength and frequency regions of applicability of the results extends to the infrared region for typical experimental conditions. Then, standard samples with millimetric sizes seem to be able to support such excitations. Forced oscillations are also determined which should be generated in the 2DEG by external electromagnetic sources. They show an almost frequency independent wavevelength which decreases with the magnetic field. A qualitative model based in these solutions is also presented to describe a recently found new class of resonances appearing near the edge of a 2DEG in the QHE regime.
