description: The microscopic spectral density of the Wilson Dirac operator for two flavor lattice QCD is analyzed. The computation includes the leading order a^2 corrections of the chiral Lagrangian in the microscopic limit. The result is used to demonstrate how the Sharpe-Singleton first order scenario is realized in terms of the eigenvalues of the Wilson Dirac operator. We show that the Sharpe-Singleton scenario only takes place in the theory with dynamical fermions whereas the Aoki phase can be realized in the quenched as well as the unquenched theory. Moreover, we give constraints imposed by gamma_5-Hermiticity on the additional low energy constants of Wilson chiral perturbation theory.

description: Using Galois cohomology, Schmoyer characterizes cryptographic non-trivial self-pairings of the $\ell$-Tate pairing in terms of the action of the Frobenius on the $\ell$-torsion of the Jacobian of a genus 2 curve. We apply similar techniques to study the non-degeneracy of the $\ell$-Tate pairing restrained to subgroups of the $\ell$-torsion which are maximal isotropic with respect to the Weil pairing. First, we deduce a criterion to verify whether the jacobian of a genus 2 curve has maximal endomorphism ring. Secondly, we derive a method to construct horizontal $(\ell,\ell)$-isogenies starting from a jacobian with maximal endomorphism ring.

description: In evolution, the effects of a single deleterious mutation can sometimes be compensated for by a second mutation which recovers the original phenotype. Such epistatic interactions have implications for the structure of genome space - namely, that networks of genomes encoding the same phenotype may not be connected by single mutational moves. We use the folding of RNA sequences into secondary structures as a model genotype-phenotype map and explore the neutral spaces corresponding to networks of genotypes with the same phenotype. In most of these networks, we find that it is not possible to connect all genotypes to one another by single point mutations. Instead, a network for a phenotypic structure with $n$ bonds typically fragments into at least $2^n$ neutral components, often of similar size. While components of the same network generate the same phenotype, they show important variations in their properties, most strikingly in their evolvability and mutational robustness. This heterogeneity implies contingency in the evolutionary process.

description: Die Bundesregierung hat die Förderung von Beschäftigung mit niedrigen Bruttoarbeitsentgelten (Midijobs) zum 1. Januar 2023 ausgeweitet und die Verdienstobergrenze auf 2 000 Euro brutto monatlich angehoben. Rund 6,2 Millionen Menschen mit einem Midijob profitieren von reduzierten Sozialbeiträgen. Zudem erhalten sie die vollen Rentenansprüche, obwohl sie verminderte Rentenbeiträge zahlen. Möglich wird das durch eine Umverteilung innerhalb des Versichertenkollektivs. Die Umverteilung widerspricht dem Prinzip der Beitragsäquivalenz. Dieser Wochenbericht untersucht den finanziellen Umfang der zusätzlichen Rentenanwartschaften und wie zielgenau die Förderung ausfällt. Der Gesetzlichen Rentenversicherung (GRV) entgehen aufgrund der reduzierten Beiträge Einnahmen in Höhe von etwa einer Milliarde Euro im Jahr. Die Beiträge zur GRV fallen je entlasteter Person um durchschnittlich zwölf Euro im Monat niedriger aus als ohne Midijob-Regelung. Betrachtet man die Förderung nach Nettoäquivalenzeinkommen oder auch nach dem individuellen Bruttostundenlohn, dann zeigt sich, dass diese Politik wenig zielgenau ist. Von der Förderung profitieren auch Personen mit hohem Nettoäquivalenzeinkommen oder hohem Stundenlohn, aber geringem Erwerbsumfang. Wenn die Politik in der Gesetzlichen Rentenversicherung umverteilen will, dann sollte sie diese Umverteilung neu justieren und zielgerichteter gestalten. Um Altersarmut effektiver zu bekämpfen, sollte direkt bei den Rentenanwartschaften der betroffenen Personen angesetzt oder der Grundrentenzuschlag erweitert werden.

description: Once the critical temperature of a cosmological boson gas is less than the critical temperature, a Bose-Einstein Condensation process can always take place during the cosmic history of the universe. Zero temperature condensed dark matter can be described as a non-relativistic, Newtonian gravitational condensate, whose density and pressure are related by a barotropic equation of state, with barotropic index equal to one. In the present paper we analyze the effects of the finite dark matter temperature on the properties of the Bose-Einstein Condensed dark matter halos. We formulate the basic equations describing the finite temperature condensate, representing a generalized Gross-Pitaevskii equation that takes into account the presence of the thermal cloud. The static condensate and thermal cloud in thermodynamic equilibrium is analyzed in detail, by using the Hartree-Fock-Bogoliubov and Thomas-Fermi approximations. The condensed dark matter and thermal cloud density and mass profiles at finite temperatures are explicitly obtained. Our results show that when the temperature of the condensate and of the thermal cloud are much smaller than the critical Bose-Einstein transition temperature, the zero temperature density and mass profiles give an excellent description of the dark matter halos. However, finite temperature effects may play an important role in the early stages of the cosmological evolution of the dark matter condensates.

Why Are AGN and Host Galaxies Misaligned?

description: It is well-established observationally that the characteristic angular momentum axis on small scales around AGN, traced by radio jets and the putative torus, is not well-correlated with the large-scale angular momentum axis of the host galaxy. In this paper, we show that such misalignments arise naturally in high-resolution simulations in which we follow angular momentum transport and inflows from galaxy to sub-pc scales near AGN, triggered either during galaxy mergers or by instabilities in isolated disks. Sudden misalignments can sometimes be caused by single massive clumps falling into the center slightly off-axis, but more generally, they arise even when the gas inflows are smooth and trace only global gravitational instabilities. When several nested, self-gravitating modes are present, the inner ones can precess and tumble in the potential of the outer modes. Resonant angular momentum exchange can flip or re-align the spin of an inner mode on a short timescale, even without the presence of massive clumps. We therefore do not expect that AGN and their host galaxies will be preferentially aligned, nor should the relative alignment be an indicator of the AGN fueling mechanism. We discuss implications of this conclusion for AGN feedback and BH spin evolution. The misalignments may mean that even BHs accreting from smooth large-scale disks will not be spun up to maximal rotation, and so have more modest radiative efficiencies and inefficient jet formation. Even more random orientations are possible if there is further, un-resolved clumpiness in the gas, and more ordered accretion may occur if the inflow is slower and not self-gravitating.

description: We describe mixing scalar particles and Majorana fermions using Closed-Time-Path methods. From the Kadanoff-Baym equations, we obtain the charge asymmetry, that is generated from decays and inverse decays of the mixing particles. Within one single formalism, we thereby treat Leptogenesis from oscillations and recover as well the standard results for the asymmetry in Resonant Leptogenesis, which apply when the oscillation frequency is much larger than the decay rate. Analytic solutions for two mixing neutral particles in a constant-temperature background illustrate our results qualitatively. We also perform the modification of the kinetic equations that is necessary in order to take account of the expansion of the Universe and the washout of the asymmetry.

description: This study aimed to evaluate histological modifications of the vaginal mucosa after repeated microablative fractional CO2 laser treatments. As secondary objectives we evaluated the clinical effects associated with repeated microablative fractional CO2 laser treatments using validated questionnaires. A prospective intervention study was performed in the Division of Gynecology and Obstetrics, Urogynecology Unit, IRCCS San Raffaele Scientific Institute with 15 postmenopausal women complaining of genitourinary syndrome of menopause symptoms. The cohort of patients was submitted to at least two previous laser treatment cycles in the past years. The Vaginal Health Index (VHI), visual analog scale (VAS), Female Sexual Function Index (FSFI), Urinary Distress Inventory-6 (UDI-6), International Consultation on Incontinence Questionnaire – Urinary Incontinence (ICIQ-UI) and 5-point Likert scale were used. Moreover, histological examinations were carried out on all samples. At 4 weeks after the last treatment, the VHI score and all FSFI items were significantly increased compared with baseline. We observed a statistically significant decrease in both frequency and severity for all urinary symptoms after the follow-up. We observed a statistically significant increase in the number of epithelial cell layers with a consequent increase in epithelial thickness, in the number of glycogen-filled cells and in the number of papillae after the laser treatment. No signs of fibrosis were observed as neovascularization was observed in each woman. This is the first study demonstrating the histological persistency of efficacy in repeated annually laser treatment cycles, with tissue changes always leading to regenerative results without any sign of fibrosis.

description: This paper studies the three-user finite-field multi-way relay channel, where the users exchange messages via a relay. The messages are arbitrarily correlated, and the finite-field channel is linear and is subject to additive noise of arbitrary distribution. The problem is to determine the minimum achievable source-channel rate, defined as channel uses per source symbol needed for reliable communication. We combine Slepian-Wolf source coding and functional-decode-forward channel coding to obtain the solution for two classes of source and channel combinations. Furthermore, for correlated sources that have their common information equal their mutual information, we propose a new coding scheme to achieve the minimum source-channel rate.

The implementation of oral health regulation in long-term care facilities
Creators: name: Jiang, Caroline Yueh Wen
Publisher: name: University of British Columbia
Year: 2012

description: Background: Poor oral health in long-term care (LTC) facilities is rampant and currently there is no effective strategy for improving daily oral healthcare in most of them. The government of British Columbia has implemented an oral health regulation for joint responsibility between dental professionals and LTC administrators to maintain the daily oral healthcare of residents in their care; however, it seems that conflicting priorities persist and are a barrier to achieving optimal oral health for residents. Research Questions: How has the governmental regulation on oral healthcare in LTC been developed, implemented and sustained? Methods: I conducted a secondary analysis of open-ended interviews with 14 LTC administrators undertaken before the regulation was implemented. Subsequently I conducted similar interviews with five government officials and five administrators to explore how the regulation was developed and implemented. Participants for interviews were selected purposefully to obtain a comprehensive response to my questions. I used a constant comparison technique to analyze relationships between the various perspectives, and I determined the trustworthiness of my findings by triangulating them with published literature on this topic, and by allowing participants to comment on them. Results: Before the regulation was implemented administrators emphasized a need for constant reminders, continuing education and administrative accountability to maintain the daily oral healthcare in LTC facilities. Government officials developed the regulation so that facility residents would receive a clinical examination annually by a dental professional. However, LTC administrators seemed unaware of this regulation, and when brought to their attention did not expect it to be assessed by government inspectors. This disregard for regulation was confirmed by the inspectors who explained that they do not enquire about daily oral healthcare of residents unless there is a written recommendation from a dental professional for treatment of specific mouth problems. Conclusions: The regulation to manage oral healthcare in LTC facilities is not being implemented or sustained as intended because of inadequate collaboration between dental professionals, administrators, and government inspectors.

Metamagnetism and Lifshitz Transitions in Models for Heavy Fermions

description: We investigate metamagnetic transitions in models for heavy fermions by considering the doped Kondo lattice model in two dimensions. Results are obtained within the framework of dynamical mean field and dynamical cluster approximations. Universal magnetization curves for different temperatures and Kondo couplings develop upon scaling with the lattice coherence temperature. Furthermore, the coupling of the local moments to the magnetic field is varied to take into account the different Landé factors of localized and itinerant electrons. The competition between the lattice coherence scale and the Zeeman energy scale allows for two interpretations of the metamagnetism in heavy fermions: Kondo breakdown or Lifshitz transitions. By tracking the single-particle residue through the transition, we can uniquely conclude in favor of the Lifshitz transition scenario. In this scenario, a quasiparticle band drops below the Fermi energy which leads to a change in topology of the Fermi surface.

description: Studies have shown racial/ethnic differences in the prevalence of vasomotor symptoms (VMS), sleep disturbance and VMS treatment in menopause. To assess the reproducibility of these differences, we systematically reviewed observational studies, published in 2000–2021, reporting the prevalence/incidence of VMS, sleep disturbance or treatment use in menopausal women stratified by race/ethnicity. We screened 3799 records from PubMed and Embase and included 27 papers (19 studies). No incidence data were found. Prevalence data varied widely, but some common patterns emerged. In all five studies comparing VMS between Black women and White, Hispanic and/or East Asian women, the prevalence was highest in Black women and lowest in East Asian women. The prevalence of sleep disturbance overall was compared among Black, White and East Asian women in two study populations, and was highest in White women in both papers. Sleep disturbance was more common than VMS in East Asian women. In all four studies comparing hormone therapy use between White women and Black and/or East Asian women, treatment use was more common in White women. These results highlight the need for individualized counseling and treatment, outreach to under-served minorities, and standardized definitions and outcome measures for VMS and sleep disturbance for future studies.

description: Im August 2022 hat der US- Kongress ein umfangreiches Bundesgesetz, den Inflation Reduction Act (IRA), verabschiedet, das der US-Wirtschaft zu mehr Wachstum und Resilienz verhelfen soll. Es ist ein massives staatliches Investitions- und Ausgabenprogramm in den Sozialstaat, in die bundesweite Infrastruktur und in den Klima- und Umweltschutz in Höhe von geschätzt rund 430 Milliarden Dollar. Gleichzeitig soll es die Vormachtstellung der USA als größten Energieproduzenten langfristig sichern, die Reindustrialisierung der US-Wirtschaft unterstützen sowie eine starke Antwort auf Chinas wirtschaftliche und technologische Hegemonialbestrebungen geben. Die Ausgestaltung des Programms setzt enorme Anreize und gibt teils Verpflichtungen vor, Produktion in die USA zu verlagern. Diese Local-Content-Klauseln können sich stark auf die europäische Wirtschaft auswirken, wenn Produktion aus der EU in die USA verlagert wird. Dies verlangt strategische wirtschaftspolitische Antworten, die die EU teilweise schon angekündigt hat, zum Beispiel bei der Lockerung ihrer Subventionsregelungen. Aber auch an anderen Stellen müsste sie noch dringend nachjustieren, vor allem bei der sicheren Versorgung mit kritischen Rohstoffen.

The evolution of the orbit distance in the double averaged restricted 3-body problem with crossing singularities

description: We study the long term evolution of the distance between two Keplerian confocal trajectories in the framework of the averaged restricted 3-body problem. The bodies may represent the Sun, a solar system planet and an asteroid. The secular evolution of the orbital elements of the asteroid is computed by averaging the equations of motion over the mean anomalies of the asteroid and the planet. When an orbit crossing with the planet occurs the averaged equations become singular. However, it is possible to define piecewise differentiable solutions by extending the averaged vector field beyond the singularity from both sides of the orbit crossing set. In this paper we improve the previous results, concerning in particular the singularity extraction technique, and show that the extended vector fields are Lipschitz-continuous. Moreover, we consider the distance between the Keplerian trajectories of the small body and of the planet. Apart from exceptional cases, we can select a sign for this distance so that it becomes an analytic map of the orbital elements near to crossing configurations. We prove that the evolution of the 'signed' distance along the averaged vector field is more regular than that of the elements in a neighborhood of crossing times. A comparison between averaged and non-averaged evolutions and an application of these results are shown using orbits of near-Earth asteroids.

description: Oscillations of the $F(R)$ dark energy around the phantom divide line, $ω_{DE}=-1$, both during the matter era and also in the de Sitter epoch are investigated. The analysis during the de Sitter epoch is revisited by expanding the modified equations of motion around the de Sitter solution. Then, during the matter epoch, the time dependence of the dark energy perturbations is discussed by using two different local expansions. For high values of the red shift, the matter epoch is a stable point of the theory, giving the possibility to expand the $F(R)$-functions in terms of the dark energy perturbations. In the late-time matter era, the realistic case is considered where dark energy tends to a constant. The results obtained are confirmed by precise numerical computation on a specific model of exponential gravity. A novel and very detailed discussion is provided on the critical points in the matter era and on the relation of the oscillations with possible singularities.

description: Im Jahr 2021 vereinbarte die G7 mit Südafrika eine Partnerschaft für eine gerechte Energiewende (JETP). Dieses – neue – Instrument der internationalen Zusammenarbeit soll Schwellen- und Entwicklungsländer bei einer sozialgerechten Energiewende und beim Kohleausstieg unterstützen. Mit diesem Instrument sollen Partnerschaften auf Augenhöhe zwischen Gebern und Nehmern ermöglicht und so der Umbau des Energiesektors erleichtert werden. Eine Evaluierung der südafrikanischen JETP zeigt, dass es sich dabei de facto um einen internationalen Politikprozess zur Richtungsbestimmung handelt, dem aber noch die nötige Legitimation und der institutionelle Rahmen fehlen. Auch zeigt sich, dass die gegenwärtigen Finanzierungsinstrumente, die Transferleistungen meist an Konditionen knüpfen, nur bedingt effektiv sind; ihnen mangelt es im politischen Prozess häufig an der notwendigen Flexibilität. Durch eine gemeinsame Vereinbarung von Gebern und Nehmern, die auf politischen Zielen, Normen und Gegenseitigkeit beruht, kann die notwendige Zusammenarbeit und anschließende Förderung einer gerechten Energiewende hingegen erleichtert werden. Die Intensivierung politischer Dialoge, die Durchführung gegenseitiger Politikevaluationen und die Verbesserung des Regelwerks wie der Legitimität einer Zusammenarbeit können dabei probate Mittel für eine effektive Partnerschaft sein.

description: The dust-acoustic waves and their stability in the permeating dusty plasma with the Maxwellian velocity distribution are investigated. We derive the dust-acoustic wave frequency and instability growth rate in two limiting physical cases that the thermal velocity of the flowing dusty plasma is (a) much larger than, and (b) much smaller than the phase velocity of the waves. We find that the stability of the waves depend strongly on the velocity of the flowing dusty plasma in the permeating dusty plasma. The numerical analyses are made based on the example that a cometary plasma tail is passing through the interplanetary space plasma. We show that, in case (a), the waves are generally unstable for any flowing velocity, but in case (b), the waves become unstable only when the wave number is small and the flowing velocity is large. When the physical conditions are between these two limiting cases, we gain a strong insight into the dependence of the stability criterions on the physical conditions in the permeating dusty plasma.

description: The ApaI polymorphism (G > T, rs7975232) of the vitamin D receptor (VDR) gene in the risk of postmenopausal osteoporosis has been widely researched, and the results have yielded conflicts. Therefore, we performed an updated pooled analysis to comprehensively assess the association between VDR ApaI polymorphism and postmenopausal osteoporosis risk. We searched eligible studies about ApaI polymorphism and osteoporosis through the PubMed, Embase, CNKI and Wanfang databases; case–control studies containing available genotype frequencies of A/a were chosen. We used the odds ratio with 95% confidence interval to assess the strength of this association. Sensitivity analysis and publication bias assessment were performed. Trial sequential analysis (TSA) was performed to evaluate a sufficient sample. Twenty-two studies assessed the relationship between ApaI polymorphism and the risk of osteoporosis in postmenopausal women. The comprehensive analyses showed no significant association for ApaI polymorphism with postmenopausal osteoporosis in the overall population, equally valid for Asian and Caucasian subgroups with any genetic model. TSA still indicated the results were robust. The present meta-analysis suggests that the VDR ApaI genotype may not affect the risk of postmenopausal osteoporosis in Asians and Caucasians.

description: We study Weyssenhoff spin fluids in Bianchi type-I cosmological models, within the framework of torsional f(R)-gravity; the resulting field equations are derived and discussed in both Jordan and Einstein frames, clarifying the role played by the spin and the non-linearity of the gravitational Lagrangian f(R) in generating the torsional dynamical contributions. The general conservation laws holding for f(R)-gravity with torsion are employed to provide the conditions needed to ensure the preservation of the Hamiltonian constraint and the consequent correct formulation of the associated initial value problem. Examples are eventually given.

Columba : patriarch, prophet and politician. An analysis of the figure of Columba in Adomnán's Vita Columbae and Manus Ơ Donnell's Betha Colaim Chille

description: St. Columba is an iconic figure in the early Irish Christian Church. His life and works are testament to the spread of Irish monasticism and the success of Christian colonization of the British Isles. His legacy in the literary canon is simultaneously soldier, scholar and saviour. Two biographies written nearly one thousand years apart are used to analyse the saint’s life as exemplar of spiritual and political probity. The Vita Columbae, penned in the seventh century C.E. by Adomnán, the abbot of Iona, presents the figure of Columba as an early Christian soldier and pioneer; a politically savvy individual conscious of his royal heritage and dynastic responsibilities. He is a figure who bridged the gap between the secular and the ecclesiastical realms of interest, demonstrating the potential for mutual benefit arising from the co-operation between church and state which resulted in the creation of a unique Gaelic Christian identity. In contrast, stands the sixteenth century life of Columba, the Betha Colaim Chille by Manus O’ Donnell who was a direct descendant of the saint. This account inverts the characterization of Columba to reveal him as a figure of resistance to English colonization, a soldier of destiny who will remind the Gaelic peoples of their history and bring about a renaissance in Irish culture and identity. For Adomnán this identity is tied to Columba and the monastery at Iona and articulated as synonymously Irish and Christian under the banner of Columbine monasticism. O' Donnell utilizes and builds on this legacy, depicting Columba as a revolutionary figure who combines the virtues and valour of his pre-Christian forbearers, the Gaelic chieftains. This image is one that all Gaelic peoples might ascribe to and thus avoid the colonisation and consequent Anglicization by the Tudor conquest of sixteenth century Ireland. Both works are important in the development of Irish Language, literature and culture upon which ideas of 'Gaelic Identity’ were articulated. The literary tradition of Columba is a part of a larger body of work that engages with these ideas and demonstrates the importance of Columba and his legacy in the historical record.

description: We present limits on Majoron-emitting neutrinoless double-beta decay modes based on an exposure of 112.3 days with 125 kg of Xe-136. In particular, a lower limit on the ordinary (spectral index n = 1) Majoron-emitting decay half-life of Xe-136 is obtained as T_{1/2}^{0νχ^{0}} > 2.6 x 10^{24} yr at 90% C.L., a factor of five more stringent than previous limits. The corresponding upper limit on the effective Majoron-neutrino coupling, using a range of available nuclear matrix calculations, is < (0.8 - 1.6) x 10^{-5}. This excludes a previously unconstrained region of parameter space and strongly limits the possible contribution of ordinary Majoron emission modes to 0νββdecay for neutrino masses in the inverted hierarchy scheme.

description: At the beginning of the new era, the rise of the Fourth Industrial Revolution has been rapidly transforming society into a new form that has never been experienced before. While previous industrial revolutions have also contributed to societal growth through phenomenal inventions and discoveries, the Fourth Industrial Revolution has the potential to break the most conventional rule, and one that has dominated social and economic activities: physical interaction. In the near future, sitting at the office, having an in-person meeting, or going on a business trip may no longer be needed as physical barriers are destroyed by cyberspace. However, two significant issues have also risen, and the threat they pose is growing day by day.

Climate change, the by-product of the First Industrial Revolution, has been growing through the Second and the Third Industrial Revolution and has begun to express its tremendous influence. Simultaneously, cybercrimes, a newly emerging issue, have quickly grown in size through the ever-increasing cyberspace that exists today, posing enormous financial and ethical problems to society. As climate change and cybercrimes are issues thought to be mutually exclusive of one another, attempts to attack them individually have been made. However, despite the perceived differences between these two issues, they may not be entirely unrelated. This paper argues that there may be a potential connection between climate change and cybercrimes and suggests practical solutions that can be implemented to address both issues together effectively.

Do peaked solitary water waves indeed exist?
Creators: name: Liao, Shijun
Publisher: name: arXiv
Year: 2012

description: Many models of shallow water waves admit peaked solitary waves. However, it is an open question whether or not the widely accepted peaked solitary waves can be derived from the fully nonlinear wave equations. In this paper, a unified wave model (UWM) based on the symmetry and the fully nonlinear wave equations is put forward for progressive waves with permanent form in finite water depth. Different from traditional wave models, the flows described by the UWM are not necessarily irrotational at crest, so that it is more general. The unified wave model admits not only the traditional progressive waves with smooth crest, but also a new kind of solitary waves with peaked crest that include the famous peaked solitary waves given by the Camassa-Holm equation. Besides, it is proved that Kelvin's theorem still holds everywhere for the newly found peaked solitary waves. Thus, the UWM unifies, for the first time, both of the traditional smooth waves and the peaked solitary waves. In other words, the peaked solitary waves are consistent with the traditional smooth ones. So, in the frame of inviscid fluid, the peaked solitary waves are as acceptable and reasonable as the traditional smooth ones. It is found that the peaked solitary waves have some unusual and unique characteristics. First of all, they have a peaked crest with a discontinuous vertical velocity at crest. Especially, the phase speed of the peaked solitary waves has nothing to do with wave height. In addition, the kinetic energy of the peaked solitary waves either increases or almost keeps the same from free surface to bottom. All of these unusual properties show the novelty of the peaked solitary waves, although it is still an open question whether or not they are reasonable in physics if the viscosity of fluid and surface tension are considered.
