description: The COVID-19 pandemic has had broad impacts on American society. As remote work became increasingly common and population density became a liability, many people reconsidered where they live. Using mobile device data, we document the influx of people to rural areas with high scenic and recreational amenities. While an influx of people to these areas led to an early rise in COVID-19 cases and deaths, that effect was short-lived. Since mid-April, these rural areas with high amenities have experienced substantially lower disease burden. We conclude with a discussion of the risks and opportunities posed by this influx to rural communities.

description: The COVID-19 pandemic sparked the rapid transition of 1.9 million university student from in-person to remote learning during the spring of 2020. Popular press and recent research reports highlighted serious challenges many students faced during this time. Yet, some students had a good or even very good remote learning experience. The purpose of this research is to analyze student perspectives of their remote learning experiences in the early phase of the pandemic to provide valuable insights to instructors, inform instructional design, and discuss policy implications. We surveyed students from colleges of agriculture at six land-grant universities, generating a sample of 2,690 completed responses. Students described their academic experience; learning environments (living situations, internet access, etc.); health, safety and family concerns; and emotional stressors. Opportunities for active student engagement, being able to connect with the instructor, and the inclusion of reflective assignments all contributed to an improved learning experience in a specific course. We found that a positive prior online experience and differences in learning environments explained observed differences in overall learning experiences. Students who felt discriminated against in their university settings reported a more negative experience during these tumultuous times, and experiences varied significantly across universities. Contrary to the experiences of women in the labor market, students identifying as female and students living with children reported better overall experiences during the first month of the pandemic.

description: Quantum fluids of light are an emerging platform for energy efficient signal processing, ultra-sensitive interferometry and quantum simulators at elevated temperatures. Here we demonstrate the optical control of the topological excitations induced in a large polariton condensate, realising the bosonic analog of a long Josephson junction and reporting the first observation of bosonic Josephson vortices. When a phase difference is imposed at the boundaries of the condensate, two extended regions become separated by a sharp $π$-slippage of the phase and a solitonic depletion of the density, forming an insulating barrier with a suppressed order parameter. The superfluid behavior, that is a smooth phase gradient across the system instead of the sharp phase jump, is recovered at higher polariton densities and it is mediated by the nucleation of Josephson vortices within the barrier. Our results contribute to the understanding of dissipation and stability of elementary excitations in macroscopic quantum systems.

description: In March 2020, faculty across the nation were forced to suddenly transform their inperson classes to virtual platforms as a result of COVID-19 university closures. Virtual offerings continued throughout the 2020-21 academic year for most universities. We share our own observations gathered from biweekly meetings of AAEA’s Teaching, Learning, and Communication (TLC) section, where participants discuss best practices for remote instruction. Our paper addresses several themes, including the challenges of teaching in a virtual environment, the positive outcomes of the pivot to remote teaching, and perspectives regarding how university education may be forever altered when we return to the classroom.

Interpretative Phenomenological Analysis

description: No published research to date has investigated the mental health experiences of Orthodox Jewish adolescents in the UK, although anecdotally, the Jewish mental health community is aware of the prevalence of mental health difficulties amongst young people. This lack of research highlights a serious gap in how to best support this population in the community and in mainstream services. As a first step into this fieldMIR of study, this research explored the experiences of seven London-based Orthodox Jewish female therapists offering talking therapy to strictly Orthodox Jewish (Chareidi) female adolescents in the private sector, using semi-structured interviews. An interpretative phenomenological analysis of the interview data identified several themes: The therapists navigated personal and professional overlap when working within their own community, dealt with blurred boundaries, and managed the complexities of confidentiality within a close-knit community context. Furthermore, their therapeutic practice was culturally informed, and they applied cultural sensitivity with their clients. The therapists talked about how they helped Chareidi Gen Z on their journey to adulthood and how they experienced both feeling connected to their clients, and feeling disconnected when values were at odds with each other. The implications from this study included the need to engage Orthodox Jewish adolescents in future research so that their voices can be captured, the importance of continuing to increase culturally sensitive mental health promotion, education, and provision within the Chareidi community, and for mainstream services to facilitate access for the Chareidi community by prioritising culturally informed practices and community partnership work.

description: We present a unified description of temperature and entropy in spaces with either "true" or "accelerated observer" horizons: In their (higher dimensional) global embedding Minkowski geometries, the relevant detectors have constant accelerations a_{G}; associated with their Rindler horizons are temperature a_{G}/2πand entropy equal to 1/4 the horizon area. Both quantities agree with those calculated in the original curved spaces. As one example of this equivalence, we obtain the temperature and entropy of Schwarzschild geometry from its flat D=6 embedding.

description: Adipositas ist eine mit vielen Komorbiditäten einhergehende Krankheit und bereits heute eines der größten Gesundheitsrisiken weltweit. Da Übergewicht auf einem Ungleichgewicht aus aufgenommener Kalorienmenge und Energieverbrauch resultiert werden Patienten dazu angehalten ihren Lebensstil zu ändern und sich mehr zu bewegen. Es können jedoch auch psychische und endokrine Erkrankungen, psychosoziale sowie umweltbedingte Faktoren oder eine medikamentöse Therapie zur Ausbildung einer Adipositas beitragen. Patienten, die bereits ihr Körpergewicht reduziert haben, leiden häufig unter einem Plateau-Effekt. Die Regulation von Hunger- bzw. Sättigungsgefühl und Appetit findet durch ein komplexes neuroendokrines System statt, dass durch stetige Kommunikation des Gehirns und dem peripheren Gewebe kontrolliert wird. Eine Gewichtsreduktion könnte zur Aufrechterhaltung der Homöostase im Organismus eine metabolische Anpassung bewirken. Bisherige Therapieansätze decken nur unzureichend die globale Nachfrage und gehen mit vielen, teils schwerwiegenden Nebenwirkungen einher. Ein vielversprechender Ansatz zu Behandlung von Adipositas ist die Entwicklung von Multitarget-Wirkstoffen. CLEMMENSEN et al. zeigten, dass die gleichzeitige Gabe des TRPM8-Agonisten Icilin und des nAChR α3β4-Agonisten DMPP synergistisch das Gewicht von DIO-Mäusen reduzierte. Daher stellen diese beiden Wirkstoffe einen interessanten Ausgangspunkt für die potentielle Entwicklung eines Hybridwirkstoffs dar. Im ersten Teil dieser Arbeit wurde daher in Kooperation mit der Firma SANOFI-AVENTIS die SAR von Icilin und DMPP durch Derivatsynthesen untersucht. Zudem wurden Konjugate aus Icilin und DMPP synthetisiert und gegenüber dem TRPM8 und dem nAChR α3β4 getestet. Aufgrund einer frühzeitig erkannten Labilität des Icilin-Strukturmotivs gegenüber Licht und Sauerstoff, wurden zudem Konjugate aus DMPP und Menthol als alternativer TRPM8-Agonist entwickelt und in vitro getestet. Im zweiten Teil dieser Arbeit wurden weitere DMPP-Derivate bereitgestellt und in Kooperation mit Prof. Dr. MARTIN GÖTTLICHER auf ihr Potenzial zur Laktatfreisetzung in BAT-Zellen sowie Leberzellen untersucht. Die daraus gewonnenen Informationen dienten zur Entwicklung potenter sowie selektiver Verbindungen und trugen maßgeblich zur Aufklärung eines zusätzlichen, mitochondrialen Wirkmechanismus von DMPP bei.

description: In a recent Letter (Phys. Rev. Lett.78, 1552 (1997) ), Zaikin, Golubev, van Otterlo, and Zimanyi criticized the phenomenological time-dependent Ginzburg-Laudau model which I used to study the quantum phase-slippage rate for superconducting wires. They claimed that they developed a "microscopic" model, made qualitative improvement on my overestimate of the tunnelling barrier due to electromagnetic field. In this comment, I want to point out that, i), ZGVZ's result on EM barrier is expected in my paper; ii), their work is also phenomenological; iii), their renormalization scheme is fundamentally flawed; iv), they underestimated the barrier for ultrathin wires; v), their comparison with experiments is incorrect.

description: We discuss the radial spectrum of light scalar mesons in the framework of spectral sum rules in the large-Nc (planar) limit of QCD. Two methods based on the use of linear radial Regge trajectories are presented. A special emphasis is placed on the appearance of scalar isoscalar state near 0.5 GeV. Within the considered sum rules, the existence of this meson (which could be a large-Nc counterpart to the sigma-meson) is closely related with existence of resonances in the vector channels and on the radial scalar trajectory.

The tails of the velocity gradients probability distribution function (PDF) are analyzed by saddle-point approximation in the path integral describing the velocity statistics. The structure of the saddle-point (instanton), that is velocity field configuration realizing the maximum of probability, is studied numerically in details. The numerical results allow us to find analytical solution for the long-time part of the instanton. Its careful analysis confirms the result of [Phys. Rev. Lett. 78 (8) 1452 (1997) [chao-dyn/9609005]] based on short-time estimations that the left tail of PDF has the form ln P(u_x) \propto -|u_x|^(3/2).

description: We show that dynamical symmetry methods can be applied to Hamiltonians with periodic potentials. We construct dynamical symmetry Hamiltonians for the Scarf potential and its extensions using representations of su(1,1) and so(2,2). Energy bands and gaps are readily understood in terms of representation theory. We compute the transfer matrices and dispersion relations for these systems, and find that the complementary series plays a central role as well as non-unitary representations.

description: We employ the variational method to study the properties such as masses, decay constants, oscillation frequency and branching ratios of leptonic decays of heavy flavour mesons with linear cum coulomb Cornell potential. Gaussian function, Coulomb wave function and Airy function are taken as the trial wave-function of variational method in this study. Our analysis suggests that Gaussian trial wave-function provides results which are in close proximity with the experimental results. We also make a comparison with the results from QCD Sum rules and lattice QCD, as well as with recent PDG data.

The ``wind'' consists of H/He from an accreted envelope, and the simulation demonstrates that this breaking wave mechanism can produce a well-mixed layer of H/He with C/O from the white dwarf above the surface. Material from this mixed layer may then be transported throughout the accreted envelope by convection, which would enrich the C/O abundance of the envelope as is expected from observations of novae.

Pre-big bang bubbles from the gravitational instability of generic string vacua

description: We formulate the basic postulate of pre-big bang cosmology as one of ``asymptotic past triviality'', by which we mean that the initial state is a generic perturbative solution of the tree-level low-energy effective action. Such a past-trivial ``string vacuum'' is made of an arbitrary ensemble of incoming gravitational and dilatonic waves, and is generically prone to gravitational instability, leading to the possible formation of many black holes hiding singular space-like hypersurfaces. Each such singular space-like hypersurface of gravitational collapse becomes, in the string-frame metric, the usual big-bang t=0 hypersurface, i.e. the place of birth of a baby Friedmann universe after a period of dilaton-driven inflation. Specializing to the spherically-symmetric case, we review and reinterpret previous work on the subject, and propose a simple, scale-invariant criterion for collapse/inflation in terms of asymptotic data at past null infinity. Those data should determine whether, when, and where collapse/inflation occurs, and, when it does, fix its characteristics, including anisotropies on the big bang hypersurface whose imprint could have survived till now. Using Bayesian probability concepts, we finally attempt to answer some fine-tuning objections recently moved to the pre-big bang scenario.

The anomalous properties are explained, and specifically the behavior of the resistivity, Hall constant, and thermoelectric power. High-temperature superconductivity results from transitions between pair states of quasielectrons and stripons.

AGN Black Hole Masses and Bolometric Luminosities

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Black hole mass, along with mass accretion rate, is a fundamental property of active galactic nuclei. Black hole mass sets an approximate upper limit to AGN energetics via the Eddington limit. We collect and compare all AGN black hole mass estimates from the literature; these 177 masses are mostly based on the virial assumption for the broad emission lines, with the broad-line region size determined from either reverberation mapping or optical luminosity. We introduce 200 additional black hole mass estimates based on properties of the host galaxy bulges, using either the observed stellar velocity dispersion or using the fundamental plane relation to infer $σ$; these methods assume that AGN hosts are normal galaxies. We compare 36 cases for which black hole mass has been generated by different methods and find, for individual objects, a scatter as high as a couple of orders of magnitude. The less direct the method, the larger the discrepancy with other estimates, probably due to the large scatter in the underlying correlations assumed. Using published fluxes, we calculate bolometric luminosities for 234 AGNs and investigate the relation between black hole mass and luminosity. In contrast to other studies, we find no significant correlation of black hole mass with luminosity, other than those induced by circular reasoning in the estimation of black hole mass. The Eddington limit defines an approximate upper envelope to the distribution of luminosities, but the lower envelope depends entirely on the sample of AGN included. For any given black hole mass, there is a range in Eddington ratio of up to three orders of magnitude.

description: In this article we present a new outlook on the cosmology, based on the quantum model proposed by M. Hall, D.-A. Deckert and H. Wiseman (HDW). In continuation of the idea of that model we consider finitely many classical homogeneous and isotropic universes whose evolutions are determined by the standard Einstein-Friedman equations but that also interact with each other quantum-mechanically via the mechanism proposed by HDW. The crux of the idea lies in the fact that unlike every other interpretation of the quantum mechanics, the HDW model requires no decoherence mechanism and thus allows the quantum mechanical effects to manifest themselves not just on micro-scale, but on a cosmological scale as well. We further demonstrate that the addition of this new quantum-mechanical interaction lead to a number of interesting cosmological predictions, and might even provide natural physical explanations for the phenomena of ``dark matter'' and ``phantom fields''.

description: We solve exactly the (linear order) equations for tensor and scalar perturbations over the homogeneous, isotropic, open pre-big bang model recently discussed by several authors. We find that the parametric amplification of vacuum fluctuations (i.e. particle production) remains negligible throughout the perturbative pre-big bang phase.

Periodic orbit action correlations in the Baker map
Creators: name: Tanner, Gregor
Publisher: name: arXiv
Year: 2000
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: Periodic orbit action correlations are studied for the piecewise linear, area-preserving Baker map. Semiclassical periodic orbit formulae together with universal spectral statistics in the corresponding quantum Baker map suggest the existence of universal periodic orbit correlations. The calculation of periodic orbit sums for the Baker map can be performed with the help of a Perron-Frobenius type operator. This makes it possible to study periodic orbit correlations for orbits with period up to 500 iterations of the map. Periodic orbit correlations are found to agree quantitatively with the predictions from random matrix theory up to a critical length determined by the semiclassical error. Exponentially increasing terms dominate the correlations for longer orbits which are due to the violation of unitarity in the semiclassical approximation.

IMPROVING PERCEPTIONS OF MATERNAL RESPECTFUL CARE AMONG BLACK WOMEN
Creators: name: Kelly, Sharilyn
Publisher: name: Zenodo
Year: 2024

description: Black women have two to three times the adjusted risk for severe maternal morbidity, with over half of these cases reported as preventable. A lack of respectful maternity care (RMC) may influence this increased risk. RMC is a philosophy that emphasizes the fundamental human rights of birthing women and supports their individual needs and preferences. RMC can help mitigate racial and ethnic outcome disparities by creating psychological safety for the obstetric patient. This quality improvement project aimed to enrich Black women's birthing experience and perceptions of RMC by implementing a patient-centered communication technique based on the 2022 Association of Women's Health, Obstetric, and Neonatal Nurses Respectful Maternity Framework and Evidence-Based Clinical Practice Guideline recommendations. Perinatal nurses completed education modules regarding RMC at an acute care hospital's Birth Care Center in Southern California. Postpartum patients' perceptions of care before and after the intervention were surveyed prior to discharge. The results were stratified by race and ethnicity, showing limited participation by Black postpartum patients. Despite the small number of participants, RMC may have positively impacted Black patients' perception of respectful maternal care. Future studies with larger samples are needed to confirm RMC as an effective strategy to address perceptions of respectful maternal care among Black women. Additional research is necessary to determine if RMC is an intervention that can mitigate the clinical outcome disparities of Black birthing patients feel respected, honored, and heard.

description: We present a combined analytical and numerical approach based on the Mori projection operator formalism and Monte Carlo simulations to study surface diffusion within the lattice-gas model. In the present theory, the average jump rate and the susceptibility factor appearing are evaluated through Monte Carlo simulations, while the memory functions are approximated by the known results for a Langmuir gas model. This leads to a dynamical mean field theory (DMF) for collective diffusion, while approximate correlation effects beyond DMF are included for tracer diffusion. We apply our formalism to three very different strongly interacting systems and compare the results of the new approach with those of usual Monte Carlo simulations. We find that the combined approach works very well for collective diffusion, whereas for tracer diffusion the influence of interactions on the memory effects is more prominent.

description: Since the first report of graphdiyne nanomembranes synthesis in 2010, different novel graphdiyne nanosheets have been fabricated. In a latest experimental advance, triphenylene-graphdiyne (TpG), a novel two-dimensional (2D) material was fabricated using the liquid/liquid interfacial method. In this study, we employed extensive first-principles simulations to investigate the mechanical/failure, thermal stability, electronic and optical properties of single-layer TpG. In addition, we predicted and explored the properties of nitrogenated-, phosphorated- and arsenicated-TpG monolayers. Our results reveal that TpG, N-TpG, P-TpG and As-TpG nanosheets can exhibit outstanding thermal stability. These nanomembranes moreover were found to yield linear elasticity with considerable tensile strengths. Notably, it was predicted that monolayer TpG, As-TpG, P-TpG and N-TpG show semiconducting electronic characters with direct band-gaps of 1.94 eV, 0.88 eV, 1.54 eV and 1.91 eV, respectively, along with highly attractive optical properties. We particularly analyzed the application prospect of these novel 2D materials as anodes for Li-ion batteries. Remarkably, P-TpG and N-TpG nanosheets were predicted to yield ultrahigh charge capacities of 1979 mAh/g and 2664 mAh/g, respectively, for Li-ions storage. The acquired results by this work suggest TpG based nanomembranes as highly promising candidates for the design of flexible nanoelectronics and energy storage devices.

description: The Magellan active optics system has been operating continuously on the Baade 6.5-m since the start of science operations in February 2001. The active optical elements include the primary mirror, with 104 actuators, and the secondary mirror, with 5 positional degrees of freedom. Shack-Hartmann (SH) wavefront sensors are an integral part of the dual probe guiders. The probes function interchangeably, with either probe capable of guiding or wavefront sensing. In the course of most routine observing stars brighter than 17th magnitude are used to apply corrections once or twice per minute. The rms radius determined from roughly 250 SH spots typically ranges between 0.05" and 0.10". The spot pattern is analyzed in terms of a mixture of 3 Zernike polynomials (used to correct the secondary focus and decollimation) and 12 bending modes of the primary mirror (used to compensate for residual thermal and gravitational distortions). Zernike focus and the lowest order circularly symmetric bending mode, known affectionately as the "conemode," are sufficiently non-degenerate that they can be solved for and corrected separately.

description: National research evaluation exercises provide a comparative measure of research performance of the nation's institutions, and as such represent a tool for stimulating research productivity, particularly if the results are used to inform selective funding by government. While a school of thought welcomes frequent changes in evaluation criteria in order to prevent the subjects evaluated from adopting opportunistic behaviors, it is evident that the "rules of the game" should above all be functional towards policy objectives, and therefore be known with adequate forewarning prior to the evaluation period. Otherwise, the risk is that policy-makers will find themselves faced by a dilemma: should they reward universities that responded best to the criteria in effect at the outset of the observation period or those that result as best according to rules that emerged during or after the observation period? This study verifies if and to what extent some universities are penalized instead of rewarded for good behavior, in pursuit of the objectives of the "known" rules of the game, by comparing the research performances of Italian universities for the period of the nation's next evaluation exercise (2004-2008): first as measured according to criteria available at the outset of the period and next according to those announced at the end of the period.
