description: In this work we explore the physics associated to Calabi-Yau (CY) n-folds that can be described as a fibration in more than one way. Beginning with F-theory vacua in various dimensions, we consider limits/dualities with M-theory, type IIA, and heterotic string theories. Our results include many M-/F-theory correspondences in which distinct F-theory vacua - associated to different elliptic fibrations of the same CY n-fold - give rise to the same M-theory limit in one dimension lower. Examples include 5-dimensional correspondences between 6-dimensional theories with Abelian, non-Abelian and superconformal structure, as well as examples of higher rank Mordell-Weil geometries. In addition, in the context of heterotic/F-theory duality, we investigate the role played by multiple K3- and elliptic fibrations in known and novel string dualities in 8-, 6- and 4-dimensional theories. Here we systematically summarize nested fibration structures and comment on the roles they play in T-duality, mirror symmetry, and 4-dimensional compactifications of F-theory with G-flux. This investigation of duality structures is made possible by geometric tools developed in a companion paper [1].

Finite Element Analysis of Geosynthetic Reinforced Pile-Supported (GRPS) Embankments
Creators: name: Haleluya, Mesfin
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: A large number of projects are now being carried out on soft ground due to the limitation of land availability for infrastructure projects in many countries. In addition, embankments are often required in many civil engineering construction projects involving infrastructure development to elevate the ground level. However, the undesirable characteristics associated with soft soils such as inadequate bearing capacity and large settlements/displacements, which can occur over a long time made embankment construction over soft ground is a challenging task. Several researches in the past have shown that Geosynthetic Reinforced Piled Embankment Systems (GRPES) are attractive solutions for such problems. Thus, a finite element model was carried out using the finite element software ABAQUS in order to investigate the behavior of GRPS embankments and improve the existing knowledge in the area. The role of pile supports and geosynthetic reinforcement was investigated using a two-dimensional numerical model with three different analysis cases i.e. when the soft soil is not improved - case 1, when a pile support is used in the soft soil - case 2, and when a pile support and geosynthetic reinforcement are used together - case 3. It is observed that there is 80% reduction in lateral displacement in case 2 than case 1 and 12% reduction in case 3 than case 2. The incorporation of piles to the soft soil has shown a 2.65% increase in vertical stress and a 96% reduction in settlements. Pile settlements were found to be low by about 83% compared to the corresponding subsoil. The incorporation of geosynthetic reinforcement while the piles are present showed a slight reduction in vertical displacement. In addition, the influence of increasing the number of geosynthetic layers caused a reduction in the lateral displacement.

description: We report the synthesis of single crystals of a novel layered iridate Ba$_{21}$Ir$_9$O$_{43}$, and present the crystallographic, transport and magnetic properties of this material. The compound has a hexagonal structure with two iridium oxide layers stacked along the $c$ direction. One layer consists of a triangular arrangement of Ir$_2$O$_9$ dimers while the other layer comprises two regular octahedra and one triangular pyramid, forming inter-penetrated triangular lattices. The resistivity as a function of temperature exhibits an insulating behavior, with a peculiar $T^{-3}$ behavior. Magnetic susceptibility shows antiferromagnetic Curie-Weiss behavior with $Θ_\mathrm{CW} \simeq -$90 K while a magnetic transition occurs at substantially lower temperature of 9 K. We discuss possible valence states and effective magnetic moments on Ir ions in different local environments, and argue that the Ir ions in a unique triangular-pyramidal configuration likely carry unusually large magnetic moments.

description: Undoped iron superconductors accommodate $n=6$ electrons in five d-orbitals. Experimental and theoretical evidence shows that the strength of correlations increases with hole-doping, as the electronic filling approaches half-filling with $n=5$ electrons. This evidence delineates a scenario in which the parent compound of iron superconductors is the half-filled system, in analogy to cuprate superconductors. In cuprates the superconductivity can be induced upon electron or hole doping. In this work we propose to search for high-Tc superconductivity and strong correlations in chromium pnictides and chalcogenides with $n<5$ electrons. By means of ab-initio, slave spin and multi-orbital RPA calculations we analyse the strength of the correlations and the superconducting and magnetic instabilities in these systems with main focus on LaCrAsO. We find that electron-doped LaCrAsO is a strongly correlated system with competing magnetic interactions, being $(π,π)$ antiferromagnetism and nodal d-wave pairing the most plausible magnetic and superconducting instabilities, respectively.

description: Six billion people lack access to safe, timely, and affordable cardiac surgical care when needed. Despite these gaps and persistent disparities, recent developments have enabled a growing momentum for the field of global cardiac surgery. This article describes recent developments in the field of global cardiac surgery with a particular emphasis on academic, societal, and political momentum. It also presents an overview of the global surgery and cardiovascular health discourse that took place at the 75th World Health Assembly and look ahead toward future opportunities to move the needle toward universal access to cardiovascular healthcare. While the gaps in access to cardiac surgical care across the globe remain enormous, the growing momentum of the field of global cardiac surgery enables cautious optimism for the future. Societal efforts, increasing funding opportunities, and virtual meetings have enabled greater international dialogue within and beyond the cardiovascular community. Achievements by the global surgical and cardiovascular health communities at high-level meetings provide an entry-point for global cardiac surgery toward greater political prioritization that is more aligned with the global burden of cardiovascular surgical disease. Cardiac surgeons, other heart team members, and trainees are critical voices in accelerating momentum toward cardiovascular health equity for all. Together, we can move beyond the tipping point.

description: We consider inter-atomic forces due to resonant dipole-dipole interactions within a dimer of highly excited Rydberg atoms, embedded in an ultra-cold gas. These forces rely on a coherent superposition of two-atom electronic states, which is destroyed by continuous monitoring of the dimer state through a detection scheme utilizing controllable interactions with the background gas atoms. We show that this intrinsic decoherence of the molecular energy surface can gradually deteriorate a repulsive dimer state, causing a mixing of attractive and repulsive character. For sufficiently strong decoherence, a Zeno-like effect causes a complete arrest of interatomic forces. We finally show how short decohering pulses can controllably redistribute population between the different molecular energy surfaces.

description: The observation of a possible electromagnetic counterpart by the Fermi GBM group to the aLIGO detection of the merger of a black hole binary has spawned a number of ideas about its source. Furthermore, observations of fast radio bursts (FRBs) have similarly resulted in a range of new models that might endow black hole binaries with electromagnetic signatures. In this context, even the unlikely idea that astrophysical black holes may have significant charge is worth exploring, and here we present results from the simulation of weakly charged black holes as they orbit and merge. Our simulations suggest that a black hole binary with mass comparable to that observed in GW150914 could produce the level of electromagnetic luminosity observed by Fermi GBM ($10^{49}$ ergs/s) with a non-dimensional charge of $q \equiv Q/M = 10^{-4}$ assuming good radiative efficiency. However even a charge such as this is difficult to imagine avoiding neutralization long enough for the binary to produce its electromagnetic counterpart, and so this value would likely serve simply as an upper bound. On the other hand, one can equivalently consider the black holes as having acquired a magnetic monopole charge that would be easy to maintain and would generate an identical electromagnetic signature as the electric charges. The observation of such a binary would have significant cosmological implications, not the least of which would be an explanation for the quantization of charge itself. We also study such a magnetically charged binary in the force-free regime and find it much more radiative, reducing even further the requirements to produce the counterpart.

description: The optical response of traditional semiconductors depends on the laser excitation power used in experiments. For two-dimensional (2D) semiconductors, laser excitation effects are anticipated to be vastly different due to complexity added by their ultimate thinness, high surface to volume ratio, and laser-membrane interaction effects. We show in this article that under laser excitation the optical properties of 2D materials undergo irreversible changes. Most surprisingly these effects take place even at low steady state excitation, which is commonly thought to be non-intrusive. In low temperature photoluminescence (PL) we show for monolayer (ML) MoSe2 samples grown by different techniques that laser treatment increases significantly the trion (i.e. charged exciton) contribution to the emission compared to the neutral exciton emission. Comparison between samples exfoliated onto different substrates shows that laser induced doping is more efficient for ML MoSe2 on SiO2/Si compared to h-BN and gold. For ML MoS2 we show that exposure to laser radiation with an average power in the $μ$W/$μ$m$^2$ range does not just increase the trion-to-exciton PL emission ratio, but may result in the irreversible disappearance of the neutral exciton PL emission and a shift of the main PL peak to lower energy.

Survey on the Assessment of Mother's Experiences And Satisfactions With Health Extension Program Related to Antenatal Care In Kirkos Sub-City, Addis Ababa, Ethiopia
Creators: name: G/Hiwo, Abebe
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Background: One of the focus areas in Health Extension Program of Ethiopia is maternal health. Client satisfaction is considered as one of the most wanted outcomes of health care and it is directly related with utilization of HEP. On the other hand, there is no ample information on users' awareness about the service provided in the HEP. Therefore, this study is intended to assess mothers' experiences and satisfaction with health extension service in Kirkos sub city, Addis Ababa. Objective: The objective of this study was to assess mothers` experience and satisfaction with HEP related to antenatal care in kirkos sub-city, Addis Ababa, Ethiopia Methods: A community based cross sectional study employed by quantitative data collecting method was used. The data was conducted from April- May 2014 in kirkos sub-city, Addis Ababa, Ethiopia. In randomly selected seven woredas of the sub city, a total of 290 mothers were included in the study. Systematic sampling technique was used to select study respondents. Binary and Multivariate logistic regression was applied to identify the predictor factor for satisfaction. Results: 26.6 % of the respondents had an experience of interaction with health extension workers during one year prior to the survey. 46.8% of mothers had only one follow up. 30.4 % of them had twice of the service. The average score of Mothers' Satisfaction was 109 (42.7 %) of the mothers satisfied with the health extension program in relation to Antenatal care. (28.6%) Mothers were satisfied with courtesy, (28.6%) of the mothers with quality of care. Involvement of husband in HEP was found to be statistically significant independent predictor for satisfaction of mother on HEP with AOR =5.93(1.20 -29.22). Involvement of husband in the HEP increases almost six times satisfaction of mothers in using the service delivered by the Hews. This study is supported by the study carried out in Jimma southern Ethiopia. Conclusion: The HEP is implemented in urban community but mothers are not attracted by the service. In Addis Ababa there are different health service alternatives which the mother can get ANC service. The involvement of husbands in the HEP was found to be a main predictor for the satisfaction of mothers with HEP related to ANC. The experience of mothers ever visited by HEWs during the last one year was very low but the Knowledge of mothers about the services delivered by health extension workers are good. In this study the satisfaction and experience of interpersonal relationship were reported to be low. Key words: HEP, Satisfaction, Experience, HEWs, Ethiopia

description: The exact factorization of an electron-nuclear wavefunction [A. Abedi, N. T. Maitra, and E. K. U. Gross, Phys. Rev. Lett. 105, 123002 (2010)] allows us to define the rigorous nuclear time-dependent Schrödinger equation (TDSE) with a time-dependent potential-energy surface (TDPES) that fully accounts for the coupling to the electronic motion and drives the nuclear wavepacket dynamics. Here, we study whether the propagation of multiple classical trajectories can reproduce the quantum nuclear motion in strong-field processes when their motions are governed by the quantum Hamilton-Jacobi equation derived by applying Bohmian mechanics to this exact nuclear TDSE. We demonstrate that multiple classical trajectories propagated by the force from the gradient of the exact TDPES plus the Bohmian quantum potential can reproduce the strong-field dissociation dynamics of a one-dimensional model of the H$_2^+$ molecule. Our results show that the force from the Bohmian quantum potential plays a non-negligible role in yielding quantum nuclear dynamics in the strong-field process studied here, where ionization and/or splitting of nuclear probability density occurs.

description: Everyday people spend much time in vehicles. Either riding or driving has become a part of our life. A comfortable thermal sensation brought on occupants contributes a lot to our life and work. On the contrast, a bad and uncomfortable thermal environment may get human ill and even risk their life. Air distributions in the passenger trains are crucial to thermal comfort and air quality. Computational fluid dynamics (CFD) has been playing an important role in evaluating and designing various air distributions. Recent advances in CFD approaches and turbulence models provide a great potential of improving predict on accuracy of air distributions in enclosed environments. The objective of the present research was to investigate the air flow distribution inside the passenger train through the route of Addis Ababa –Djibouti as well as to show the terminate velocity (draft) below 0.7 m/s around the passenger's necks by use numerical simulations. For the study purpose, the passenger train coach was simulated by creating the model in CATIA & Ansys design modeller and assessed by CFD analysis using commercial code FLUENT (ANSYS14.5) software for solving, analysing and post processing the results. Air flow pattern have been studied in the interior of passenger train within different angle of air diffuser arrangement which are at zero, 15 and 25degress in which their results have showed that the passengers 'neck area speed were an average 0.681,0.7146 and 0.7057m/s respectively. Its result obtained from the numerical simulation agreed well with the comfort region which is below 0.7 m/s so that the air diffuser arrangement at an angle zero degree is better than the 15 and 25 degrees. Though the numerical simulation provides considerable insight into the theoretical indoor airflow distribution, the underlying assumptions that went into the modelling are questionable. Experimental studies will be necessary to develop a more accurate model if it possible.

description: In this paper we investigated the long-term evolution of the pulse-period in the high-mass X-ray binary LMC X-4 by taking advantage of more than 43~yrs of measurements in the X-ray domain. Our analysis revealed for the first time that the source is displaying near-periodical variations of its spin period on a time scale of roughly 6.8~yrs, making LMC X-4 one of the known binary systems showing remarkable long term spin torque reversals. We discuss different scenarios to interpret the origin of these torque reversals.

According to the discussion in [1] one can define BMS-analogous supertranslation and superrotation for spacetime with black hole in Gaussian null coordinates. In the leading and subleading orders of near horizon approximation, the infinitely degenerate black hole solutions are derived by considering Einstein equations with or without cosmological constant, and they are related to each other by the diffeomorphism generated by horizon supertranslation. Higher order results and degenerate Rindler horizon solutions also are given in appendices.

description: L’espérance de vie tout comme la proportion de personnes âgées dans la population augmentent, et toujours plus de personnes vieillissent à la maison. Cependant, toutes ne peuvent pas compter sur le soutien de membres de la famille proche (partenaires et enfants), en particulier sur leur accompagnement psychosocial au quotidien. Cette situation n’est pas synonyme de vulnérabilité, mais peut devenir problématique lorsque les ressources financières ou sociales viennent à manquer et que les conditions-cadres de l’État social pour l’accompagnement sont lacunaires. Un bon accompagnement dans la vieillesse, dans le sens d’un « travail relationnel de care », met l’accent sur les besoins psychosociaux des personnes âgées et leur permet de mener une vie autodéterminée, indépendamment de leur degré de dépendance à des soins. Pourtant, s’il existe en Suisse un droit pour les formes de soutien que sont l’aide et les soins, ce droit n’existe pas pour l’accompagnement dans la vieillesse. Le travail de care non rémunéré par des proches de la famille et les réseaux informels est implicitement considéré comme acquis.

We demonstrate the capabilities of this model by predicting the behaviour of topological edge states in quasi-periodic structures. A proposition to use this model in Casimir physics is presented.

description: We show that in the perturbative regime defined by the coupling constant, the theta-exact Seiberg-Witten map applied to noncommutative U(N) Yang-Mills --with or without Supersymmetry-- gives an ordinary gauge theory which is, at the quantum level, dual to the former. We do so by using the on-shell DeWitt effective action and dimensional regularization. We explicitly compute the one-loop two-point function contribution to the on-shell DeWitt effective action of the ordinary U(1) theory furnished by the theta-exact Seiberg-Witten map. We find that the non-local UV divergences found in the propagator in the Feynman gauge all but disappear, so that they are not physically relevant. We also show that the quadratic noncommutative IR divergences are gauge-fixing independent and go away in the Supersymmetric version of the U(1) theory.

description: Menschen, welche einen negativen Asylentscheid oder einen Nichteintretensentscheid erhalten, müssen die Schweiz verlassen. Während ihrem Verbleib in der Schweiz, haben die Betroffenen das Recht auf Nothilfe. Nothilfe ist eine existenzsichernde Massnahme, welche abgewiesenen Asylsuchenden die als notwendig erachteten materiellen und finanziellen Mittel zusichert. Die Nothilfebezüger*innen leben meist über Jahre in Kollektivunterkünften, in welchen sie mit einem niedrigen Geldbetrag ihren Lebensunterhalt bestreiten. Die Möglichkeit ausgeschafft zu werden bleibt bestehen. In dieser Bachelorarbeit «Leben in der Nothilfe – Eine bedürfnistheoretische Auseinandersetzung der Lebensumstände von abgewiesenen Asylsuchenden in der Nothilfe und daraus folgende Handlungsempfehlungen für die Soziale Arbeit» setzen sich Seline Weissflog und Rebekka Schwarz mit den Lebensumständen der Nothilfebezüger*innen auseinander. Dabei wird aufgezeigt, dass das Nothilfesystem ein menschenwürdiges Dasein verhindert. Aufgrund dessen stellt sich die Frage, welche Veränderungen förderlich wären, um die Lebensumstände der Nothilfebezüger*innen zu verbessern. Die konkreten Lebensumstände, sowie Veränderungsmöglichkeiten werden mittels Leitfadeninterviews mit Betroffenen und Expertinnen qualitativ erforscht. Die Ergebnisse werden mit einer sozialarbeitswissenschaftlichen Theorielinie verknüpft und daraus Handlungsempfehlungen für die Soziale Arbeit formuliert.

description: We compute the gradient expansion for anisotropic hydrodynamics. The results are compared with the corresponding expansion of the underlying kinetic-theory model with the collision term treated in the relaxation time approximation. We find that a recent formulation of anisotropic hydrodynamics based on an anisotropic matching principle yields the first three terms of the gradient expansion in agreement with those obtained for the kinetic theory. This gives further support for this particular hydrodynamic model as a good approximation of the kinetic-theory approach. We further find that the gradient expansion of anisotropic hydrodynamics is an asymptotic series, and the singularities of the analytic continuation of its Borel transform indicate the presence of non-hydrodynamic modes.
Cosmological histories from the Friedmann equation: The universe as a particle

description: In this note, we discuss how possible expansion histories of the universe can be inferred in a simple way, for arbitrary energy contents. No new physical results are obtained, but the goal is rather to discuss an alternative way of writing the Friedmann equation in order to facilitate an intuitive understanding of the possible solutions; for students and researchers alike. As has been noted in passing by others, this specific form of the Friedmann equation allows us to view the universal expansion as a particle rolling along a frictionless track. Specific examples depicted include the current concordance cosmological model as well as a stable static universal model.

description: We obtain two-dimensional exact analytic solutions for the structure of the hot accretion flows without wind. We assume that the only non-zero component of the stress tensor is $T_{rφ}$. Furthermore we assume that the value of viscosity coefficient $α$ varies with $θ$. We find radially self-similar solutions and compare them with the numerical and the analytical solutions already studied in the literature. The no-wind solution obtained in this paper may be applied to the nuclei of some cool-core clusters.

description: We present a consistent total flux catalogue for a $\sim$1 deg$^2$ subset of the COSMOS region (R.A. $\in [149.55\degr, 150.65\degr]$, DEC $\in [1.80\degr, 2.73\degr]$) with near-complete coverage in 38 bands from the far-ultraviolet to the far-infrared. We produce aperture matched photometry for 128,304 objects with i < 24.5 in a manner that is equivalent to the Wright et al. (2016) catalogue from the low-redshift (z < 0.4) Galaxy and Mass Assembly (GAMA) survey. This catalogue is based on publicly available imaging from GALEX, CFHT, Subaru, VISTA, Spitzer and Herschel, contains a robust total flux measurement or upper limit for every object in every waveband and complements our re-reduction of publicly available spectra in the same region. We perform a number of consistency checks, demonstrating that our catalogue is comparable to existing data sets, including the recent COSMOS2015 catalogue (Laigle et al. 2016). We also release an updated Davies et al. (2015) spectroscopic catalogue that folds in new spectroscopic and photometric redshift data sets. The catalogues are available for download at http://cutout.icrar.org/G10/dataRelease.php. Our analysis is optimised for both panchromatic analysis over the full wavelength range and for direct comparison to GAMA, thus permitting measurements of galaxy evolution for 0 < z < 1 while minimising the systematic error resulting from disparate data reduction methods.

description: Living microorganisms are capable of a tactic response to external stimuli by swimming towards or away from the stimulus source; they do so by adapting their tactic signal transduction pathways to the environment. Their self-motility thus allows them to swim against a traveling tactic wave, whereas a simple fore-rear asymmetry argument would suggest the opposite. Their biomimetic counterpart, the artificial microswimmers, also propel themselves by harvesting kinetic energy from an active medium, but, in contrast, lack the adaptive capacity. Here we investigate the transport of artificial swimmers subject to traveling active waves and show, by means of analytical and numerical methods, that self-propelled particles can actually diffuse in either direction with respect to the wave, depending on its speed and waveform. Moreover, chiral swimmers, which move along spiraling trajectories, may diffuse preferably in a direction perpendicular to the active wave. Such a variety of tactic responses is explained by the modulation of the swimmer's diffusion inside traveling active pulses.

description: We report the first results from our program to examine the metallicity distribution of the Milky Way nuclear star cluster connected to SgrA*, with the goal of inferring the star formation and enrichment history of this system, as well as its connection and relationship with the central 100 pc of the bulge/bar system. We present the first high resolution (R~24,000), detailed abundance analysis of a K=10.2 metal-poor, alpha-enhanced red giant projected at 1.5 pc from the Galactic Center, using NIRSPEC on Keck II. A careful analysis of the dynamics and color of the star locates it at about 26 pc line-of-sight distance in front of the nuclear cluster. It probably belongs to one of the nuclear components (cluster or disk), not to the bar-bulge or classical disk. A detailed spectroscopic synthesis, using a new linelist in the K band, finds [Fe/H]~-1.0 and [alpha/Fe]~+0.4, consistent with stars of similar metallicity in the bulge. As known giants with comparable [Fe/H] and alpha enhancement are old, we conclude that this star is most likely to be a representative of the ~10 Gyr old population. This is also the most metal poor confirmed red giant yet discovered in vicinity of the nuclear cluster of the Galactic Center. We consider recent reports in the literature of a surprisingly large number of metal poor giants in the Galactic Center, but the reported gravities of log g ~4 for these stars calls into question their reported metallicities.
