description: The possibility of observing many body localization of ultracold atoms in a one dimensional optical lattice is discussed for random interactions. In the non-interacting limit, such a system reduces to single-particle physics in the absence of disorder, i.e. to extended states. In effect the observed localization is inherently due to interactions and is thus a genuine many-body effect. In the system studied, many-body localization manifests itself in a lack of thermalization visible in temporal propagation of a specially prepared initial state, in transport properties, in the logarithmic growth of entanglement entropy as well as in statistical properties of energy levels.

description: We reconsider gravitational corrections to vacuum decay, confirming and simplifying earlier results and extending them by allowing for a non-minimal coupling of the Higgs to gravity. We find that leading-order gravitational corrections suppress the vacuum decay rate. Furthermore, we compute minor corrections to thermal vacuum decay in the SM by adding one-loop contributions to the Higgs kinetic term, two-loop contributions to the Higgs potential and allowing for time-dependent bounces.

description: We study two-point correlation functions of a massive free scalar field in de Sitter space using the heat kernel formalism. Focusing on two operators in conjugate static patches we derive a geodesic approximation to the two-point correlator valid for large mass and at late times. This expression involves a sum over two complex conjugate geodesics that correctly reproduces the large-mass, late-time limit of the exact two-point function in the Bunch-Davies vacuum. The exponential decay of the late-time correlator is associated to the timelike part of the complex geodesics. We emphasize that the late-time exponential decay is in tension with the finite maximal entropy of empty de Sitter space, and we briefly discuss how non-perturbative corrections might resolve this paradox.

description: We consider the Einstein-Dirac field equations describing a self-gravitating massive neutrino, looking for axially-symmetric exact solutions; in the search of general solutions, we find some that are specific and which have critical features, such as the fact that the space-time curvature turns out to be flat and the spinor field gives rise to a vanishing bi-linear scalar $\overlineψψ=0$ with non-vanishing bi-linear pseudo-scalar $i\overlineψγ^5ψ\not=0$: because in quantum field theory general computational methods are built on plane-wave solutions, for which bi-linear pseudo-scalar vanishes while the bi-linear scalar does not vanish, then the solutions we found cannot be treated with the usual machinery of quantum field theory. This means that for the Einstein-Dirac system there exist admissible solutions which nevertheless cannot be quantized with the common prescriptions; we regard this situation as yet another issue of tension between Einstein gravity and quantum principles. Possible ways to quench this tension can be seen either in enlarging the validity of quantum field theory or by restricting the space of the solutions of the Einstein-Dirac system of field equations.

description: We study maximally supersymmetric solutions of all gauged or deformed supergravity theories in $D \ge 3$ space-time dimensions. For vanishing background fluxes the space-time background has to be either Minkowski or anti-de Sitter. We derive a simple criterion for the existence of solutions with non-trivial fluxes and determine all supergravities that satisfy it. We show that their solutions coincide with those of the corresponding ungauged theories and conclude that the known list of maximally supersymmetric solutions is exhaustive.

description: The ultrafast response and broadband absorption of all-optical graphene switches are highly desirable features for on-chip photonic switching. However, because graphene is an atomically thin material, its absorption of guided optical modes is relatively low, resulting in high saturation thresholds and switching energies for these devices. To boost the absorption of graphene, we present a practical design of an electrically-biased all-optical graphene switch that is integrated into silicon slot waveguides, which strongly confine the optical mode in the slotted region and enhance its interaction with graphene. Moreover, the design incorporates a silicon slab layer and a hafnia dielectric layer to electrically tune the saturation threshold and the switching energy of the device by applying DC voltages of <0.5 V. Using this device, a high extinction ratio (ER) of 10.3dB, a low insertion loss (IL) of <0.7dB, and an ultra-efficient switching energy of 79fJ/bit at 0.23V bias are attainable for a 40um long switch. The reported performance metrics for this device are highly promising and are expected to serve the needs of next-generation photonic computing systems.

description: We consider the Proca theory of the real massive vector field. There is a locally conserved 4-current operator in such a theory, which one may use to define the charge operator. Accordingly, there are charged states in which the expectation value of the charge operator is non-zero. We take a close look at the charge operator and study the dynamics of the certain class of charged states. For this purpose, we discuss the mean electric field and 4-current in such states. The mean electric field has the periodically oscillating Coulomb component, whose presence explains the periodic charge oscillations. A complementary insight at such a phenomenon is provided by the mean 4-current, whose discussion leads to the identification of a certain paradox. Last but not least, we show that there is a shock wave propagating in the studied system, which affects analyticity of the mean electric field and 4-current.

description: The Earth-stopping effect plays a crucial role in the direct detection of sub-GeV dark matter. Besides the elastic scattering process, the quasi-elastic and deep inelastic scatterings between dark matter and nucleus that are usually neglected can dominate the interaction, especially in the accelerated dark matter scenarios, which may affect the dark matter detection sensitivity significantly for the underground experiments. We calculate such inelastic scattering contributions in the Earth-stopping effect and illustrate the essence of our argument with the atmospheric dark matter. With the available data, we find that the resulting upper limits on the atmospheric dark matter-nucleus scattering cross-section can differ from those only considering the elastic scattering process by one order of magnitude.

Bankers Perception Towards the Impact of Bank Specific Factors on Non Performing Loans in United Bank S.C.
Creators: name: Desalegn, Endashaw
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The study tries to examine the impact of factors affecting non-performing loans in the case of United Bank S.C. one of the major components of bank's assets is loans and advances. Failure to manage loans, which make up the lion's share of banks assets, would likely lead to the occurrence of high level of non-performing loan. In this regard NBE sets the threshold at 5%.Hence;the broad objective of the study was to assess bank specific factors of NPL in the case of United Bank S.C. Based on this broad objective, a number of specific objectives were developed. Some of the specific objectives were to identify the relationship between non-performing loan and loan growth, interest rate, credit terms, credit policy & culture, collateral, credit monitoring & risk assessment, operational efficiency, and other related objectives. In order to undertake the research both primary and secondary data was used. Primary data was collected through structured questionnaire and interview. The total population was 252 and only 103 were taken as a sample using stratified random sampling. Secondary data were collected from Provisioning report and Audited Financial statement. The collected data were analyzed using SPSS Version 20, Narration and percentages, Correlation, logistic regression and multivariate model was used. Accordingly, the result of the study indicated that, lack of loan monitoring and follow up, rapid loan growth, poor risk assessment, loan length/period, and non-collateralized loans are some of the major causes of NPL and on the other hand, interest rate and having large number of borrowers doesn't affect loan performance. All in all, based on the finding of the research, continuous policy revision, adopting relationship management approach, closely viewing the international practice, capacity development and training to credit operators and others were recommended.

description: The collapse of Landau levels under an electric field perpendicular to the magnetic field is one of the distinctive features of Dirac materials. So is the coupling of lattice deformations to the electronic degrees of freedom in the form of gauge fields which allows the formation of pseudo-Landau levels from strain. We analyze the collapse of Landau levels induced by strain on realistic Weyl semimetals hosting anisotropic, tilted Weyl cones in momentum space. We perform first-principles calculations, to establish the conditions on the external strain for the collapse of Landau levels in TaAs which can be experimentally accessed.

Disky elliptical galaxies and the allegedly over-massive black hole in the compact massive `ES' galaxy NGC 1271

description: While spiral and lenticular galaxies have large-scale disks extending beyond their bulges, and most local early-type galaxies with 10^{10} < M_*/M_Sun < 2x10^{11} contain a disk (e.g., ATLAS^3D), the early-type galaxies do possess a range of disk sizes. The edge-on, `intermediate-scale' disk in the `disky elliptical' galaxy NGC 1271 has led to some uncertainty as to what its spheroidal component is. Walsh et al. reported a directly measured black hole mass of 3x10^9 M_Sun for this galaxy; which they remarked was an order of magnitude greater than what they expected based on their derivation of the host spheroid's luminosity. Our near-infrared image analysis supports a small embedded disk within a massive spheroidal component with M_{sph,*} = (0.9+/-0.2)x10^{11} M_Sun (using M_*/L_H = 1.4 from Walsh et al.). This places NGC 1271 just 1.6-sigma above the near-linear M_bh-M_{sph,*} relation for early-type galaxies. Therefore, past speculation that there may be a systematic difference in the black hole scaling relations between compact massive early-type galaxies with intermediate-scale disks, i.e. ES galaxies such as NGC 1271, and early-type galaxies with either no substantial disk (E) or a large-scale disk (S0) is not strongly supported by NGC 1271. We additionally (i) show how ES galaxies fit naturally in the (`bulge'-to-total)-(morphological type) diagram, while noting a complication with recent revisions to the Hubble-Jeans tuning-fork diagram, (ii) caution about claims of over-massive black holes in other ES galaxies if incorrectly modelled as S0 galaxies, and (iii) reveal that the compact massive spheroid in NGC 1271 has properties similar to bright bulges in other galaxies which have grown larger-scale disks.

description: ``Do Carroll particles move?'' The answer depends on the characteristics of the particle such as its mass, spin, electric charge, and magnetic moment. A massive Carroll particle (closely related to fractons) does not move; its immobility follows from Carroll boost symmetry which implies dipole conservation, but not conversely. A massless Carroll particle may propagate by following the Hall law, consistently with the partial breaking of the Carroll boost symmetry. The framework is extended to Carroll field theory. In $d=2$ space dimensions, the Carroll group has a two-fold central extension which allows us to generalize the dynamics to massive and massless particles, including anyons. The anyonic spin and magnetic moment combine with the doubly-extended structure parameterized by two Casimir invariants interpreted as intrinsic magnetization and non-commutativity parameter. The extended Carroll particle subjected to an electromagnetic background field moves following a generalized Hall law which includes a Zeeman force. This theory is illustrated by massless, uncharged anyons with doubly-centrally extended structure we call exotic photons, which move on the horizon of a Black Hole, giving rise to an anyonic spin-Hall Effect.

description: We investigate a linear, fully coupled thermoelasticity problem for a highly heterogeneous, two-phase medium. The medium in question consists of a connected matrix with disconnected, initially periodically distributed inclusions separated by a sharp interface undergoing an a priori known interface movement due to phase transformations. After transforming the moving geometry to an $\varepsilon$-periodic, fixed reference domain, we establish the well-posedness of the model and derive a number of $\varepsilon$-independent a priori estimates. Via a two-scale convergence argument, we then show that the $\varepsilon$-dependent solutions converge to solutions of a corresponding upscaled model with distributed time-dependent microstructures.

The observed scattering rate is lower than previous theoretical estimates. The majority of the discrepancy is explained by a more accurate treatment of the scattered photon density of states. This work establishes that, contrary to previous models, there is no fundamental limit to laser-driven quantum gates from laser-induced spontaneous Raman scattering.

title: Prophecy on the page
title: the material texts of women’s prophetic discourse, 1640–1660
titleType: Subtitle
Creators: name: McGann, Claire
Publisher: name: Lancaster University
Year: 2025

description: This thesis argues that the production and form of the material text influenced the communication and reception of women’s prophetic discourse in England from 1640–1660. During this turbulent era, claims to divine inspiration enabled hundreds of women to participate in religious and political debate. The resulting discourse, broadly conceived as prophetic, was recorded and published in various print and manuscript texts, allowing readers to encounter the female prophet on the page. This thesis asks: how and by whom were these textual objects produced? Additionally, how might a prophecy’s material textual features – such as its binding, typography and page arrangement ¬– influence a reader’s interpretation of the prophetic message? These questions are explored through four case studies focusing on Grace Cary, Anna Trapnel, Sarah Wight and Eleanor Davies. Over the past forty years, critics have considered the ways in which prophetic texts framed women such as Cary, Trapnel, Wight and Davies as authoritative messengers of God’s word. Much of this scholarship has focused on the signifying role of feminised bodies, since prophetic legitimacy is often associated with corporeal weakness and receptivity to the divine Other. This thesis, however, shifts this critical focus from the body of the female prophet to the body of the text by offering the first extended bibliographic study of seventeenth-century women’s prophecy. This approach enables an extension and reframing of previous understandings of the mediation and authority of women’s spiritual discourse. An analysis of the material text reveals that prophecy’s textual objects frequently contain signs of their co-creation by multiple bodies (including printers and readers) and stage plural interventions across various copies and editions. This thesis argues that these multiple, co-created texts are not neutral mediators. Prophecy on the page is received in ways shaped and revealed by the form and production of its material texts.

description: The faintest ultraluminous X-ray sources (ULXs), those with 0.3-10 keV luminosities 1 < L_X/10^39 < 3 erg s^-1, tend to have X-ray spectra that are disk-like but broader than expected for thin accretion disks. These `broadened disk' spectra are thought to indicate near- or mildly super-Eddington accretion onto stellar remnant black holes. Here we report that a sample of bright thermal-dominant black hole binaries, which have Eddington ratios constrained to moderate values, also show broadened disk spectra in the 0.3-10 keV band at an order of magnitude lower luminosities. This broadening would be missed in studies that only look above ~2 keV. While this may suggest that broadened disk ULXs could be powered by accretion onto massive stellar remnant black holes with close to maximal spin, we argue in favor of a scenario where they are at close to the Eddington luminosity, such that radiation pressure would be expected to result in geometrically slim, advective accretion disks. However, this implies that an additional physical mechanism is required to produce the observed broad spectra at low Eddington ratios.

description: Value chains that generate an increased willingness to pay among consumers by offering enhanced levels of sustainability are widely discussed as an important strategy for creating new business opportunities and fostering food system transformation. Previous research has highlighted the importance of governance arrangements to secure the trust necessary for the establishment of sustainability-based value chains. However, how different coordination designs by private and public actors along the value chain affect trust formation is not well understood. To address this question, this paper combines the concepts of hybrid governance and multidimensional trust to guide a comparative analysis of five sustainability-based agri-food value chains in Germany as exemplary case studies. The findings show that different types of governance activities are necessary to build the capacity to address four different sources of trust: dispositional, affinitive, rational and procedural trust. Building trust capacities facilitates coordination of activities along the value chain and reliable delivery of sustainability-related value propositions. In all five cases, governance arrangements and building of trust capacities were geared towards increasing willingness to pay. Sustainability-based agri-food value chains have therefore limited potential to internalize the agri-food sector’s substantial negative externalities.

description: Unmanned aerial vehicle (UAV)-enabled wireless power transfer (WPT) systems offer significant advantages in coverage and deployment flexibility, but suffer from endurance limitations due to the limited onboard energy. This paper proposes to improve the energy efficiency of UAV-enabled WPT systems with multiple ground sensors by utilizing reconfigurable intelligent surface (RIS). Specifically, the total energy consumption of the UAV is minimized, while meeting the energy requirement of each sensor. Firstly, we consider a fly-hover-broadcast (FHB) protocol, in which the UAV radiates radio frequency (RF) signals only at several hovering locations. The energy minimization problem is formulated to jointly optimize the UAV's trajectory, hovering time and the RIS's reflection coefficients. To solve this complex non-convex problem, we propose an efficient algorithm. Specifically, the successive convex approximation (SCA) framework is adopted to jointly optimize the UAV's trajectory and hovering time, in which a minorization-maximization (MM) algorithm that maximizes the minimum charged energy of all sensors is provided to update the reflection coefficients. Then, we investigate the general scenario in which the RF signals are radiated during the flight, aiming to minimize the total energy consumption of the UAV by jointly optimizing the UAV's trajectory, flight time and the RIS's reflection coefficients. By applying the path discretization (PD) protocol, the optimization problem is formulated with a finite number of variables. A high-quality solution for this more challenging problem is obtained. Finally, our simulation results demonstrate the effectiveness of the proposed algorithm and the benefits of RIS in energy saving.

Utilization of Duckweed as a Carbon Source for the Production of Lactic Acid
Creators: name: Endriss, Ali
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Despite a great deal of research work on lactic acid fermentation in the past, the production of lactic acid from duckweed has yet to be investigated. In this study lactic acid was produced from duckweed thourgh existing technologies of saccharification/acid hydrolysis and fermentation of starch would been used for duckweed-to-lactic acid conversion. For this purpose, small fronds of duckweed plants was harvested, crushed and prepared into a solution. The duckweed slurry was subjected to acid hydrolysis. Then, fermentation of duckweed hydro-lysate was done in shake flasks using Lactobacillus plantarum species which was isolated from enset. The immediate solutions were anlysed by using UV-Spectrophotometer (concentration of lactic acid) and serial dilution methocd (viable cell count). Finally, the optimum operation conditions of fermentation (i.e. incubation time, pH and temperature) were determined by using design expert software (version 10.0.1). and the optimum incubation time, pH and temprature were 21 hours, 6.4 and 34 0 C respectively. The amount of lactic acid produced and number of viable cells at optimum operating conditions of fermentations were 15.6574g/L and 4.34004E+008.

description: Univalent categories constitute a well-behaved and useful notion of category in univalent foundations. The notion of univalence has subsequently been generalized to bicategories and other structures in (higher) category theory. Here, we zoom in on monoidal categories and study them in a univalent setting. Specifically, we show that the bicategory of univalent monoidal categories is univalent. Furthermore, we construct a Rezk completion for monoidal categories: we show how any monoidal category is weakly equivalent to a univalent monoidal category, universally. We have fully formalized these results in UniMath, a library of univalent mathematics in the Coq proof assistant.

The Effect of Consumers' Attitude on the Purchase Intentions of Imported Pharmaceutical Products in Ethiopia

description: Consumers attitude is a central concern of both product and service marketers that it is difficult to imagine any consumer research project that does not include the measurement of some aspect of consumer attitudes. Ethiopia which is classified by the world bank as a low-income country, has a population of 91.73 million people and per capita public health spending was 16.60USD, and of the total private expenditure on health care, 79.8% was out-of-pocket (Gedif, 2016). Therefore, this study is intended to measure the attitude of consumers in a developing economy like Ethiopia towards imported pharmaceuticals. After reviewing relevant literature, a research model was adapted and five hypotheses were developed. The research approach was deductive and quantitative in nature which tried to test the credibility of the adapted attitude model in the context of the pharmaceutical sector in Ethiopia. Besides, the research design used in this study was explanatory in nature. 384 questionnaires were distributed where 296 of them were returned back and 223 were found to be useful for analysis. Both descriptive and inferential statistics were used and SPSS version 24 was used for running the statistical result. Related to the findings, the study revealed that consumers' cognition, normative belief, social influence, product attributes, and utilitarian value mean score was greater than 3. The degree and direction of association or covariance between the five dimensions of consumer attitude and purchase intention was tested through correlation analysis. The Pearson correlation (r) was found to be all positive and moderate except that of utilitarian value which showed a weak relation (r = 0.149). The multiple regression analysis revealed that 44.2% of consumers' purchase intention of pharmaceuticals is explained by cognition, normative belief, social influence, product attributes, and utilitarian value. Besides, it was found out that the three hypotheses were confirmed and two hypotheses were rejected.

description: A través de este trabajo se desarrollan elementos conceptuales que permiten hacer una aproximación a la violencia política que sufren las personas LGBTIQ+ por hechos o situaciones de discriminación, prejuicios y violencia basados en la orientación sexual, identidad o expresión de género diversa, tanto en la etapa electoral al igual que durante el ejercicio del cargo de elección popular. Para lo anterior, se reconstruyeron algunos casos de violencia a partir de la información registrada en la prensa, decisiones de autoridades electorales e informes de organizaciones de la sociedad civil. Estos casos permitieron identificar que existe una violencia asociada a la ausencia de reconocimiento de la identidad de género de las personas trans, la cual en algunas ocasiones se profundiza ante la existencia de marcos electorales cisexistas y otra relacionada a los ataques que sufren las personas electas por su orientación sexual. La invitación que se hace a través de este documento de trabajo es iniciar el debate sobre la necesidad de adoptar un concepto de violencia política contra las personas LGBTIQ+ que incluya categorías específicas para la investigación, sanción y reparación de estos hechos, esto como un mecanismo para visibilizar los obstáculos que limitan la participación de este sector poblacional.

description: We combine structural and magnetic measurements to compare the different magnetic phase diagrams between the pressure and substitution studies in CeTiGe3. We report on the structural, magnetic, and electrical transport properties of single crystals of CeTi1-xVxGe3 (x = 0, 0.1, 0.2, 0.3, 0.4, 0.9, and 1), and of polycrystalline samples (x = 0.5, 0.6, 0.7, 0.8), as well as structural properties of CeTiGe3 under pressure up to 9 GPa. The ferromagnetic ordering in CeTiGe3 is suppressed with V doping in CeTi1-xVxGe3, and suggests a possible ferromagnetic quantum critical point near x = 0.45. We perform a detailed crystalline electric field (CEF) analysis, and the magnetic susceptibility data in pure CeTiGe3 and CeVGe3 can be well explained by the CEF model. The proposed CEF energy levels suggest that there is a gradual change of the ground state from 5/2 state in CeTiGe3 to 1/2 state in CeVGe3, and a suppression of CEF splitting energies near the quantum critical region. When hydrostatic pressure is used instead of chemical substitution, the quantum critical point is avoided by the appearance of magnetic phases above around 4.1 GPa. In the substitution study, the ferromagnetic and antiferromagnetic regions are well separated, whereas they touch in the pressure study. We observe a different trend in the temperature dependence of the resistivity maximum in both studies, suggesting that the CEF splitting energy is suppressed by V substitution but enhanced by pressure. We also observe different responses in lattice constants between the two studies, highlighting the fact that substitution effects cannot be reduced to chemical pressure effects only. Nevertheless, when the magnetic phase diagrams of both hydrostatic pressure and substitution are compared, we find a common critical lattice constant c = 5.78 A where the ferromagnetic ordering is suppressed in both studies.

description: This paper studies the quark condensate, magnetic moment, magnetic polarization, and magnetic susceptibility in a strong external magnetic field by employing the Dyson-Schwinger equations (DSE). The results show that these physical quantities as functions of the magnetic field. We note that the quark's spin polarizations are approximately proportional to the magnetic field magnitude. For comparison, we investigate the magnetic moments and susceptibility of the nucleon in the constituent quark model framework and demonstrate that both these quantities increase as the magnetic field rises.

description: We present the results of near-infrared (2.5--5.4um) long-slit spectroscopy of the extended green object (EGO) G318.05+0.09 with AKARI. Two distinct sources are found in the slit. The brighter source has strong red continuum emission with H2O ice, CO2 ice, and CO gas and ice absorption features at 3.0, 4.25um, 4.67um, respectively, while the other greenish object shows peculiar emission that has double peaks at around 4.5 and 4.7um. The former source is located close to the ultra compact HII region IRAS 14498-5856 and is identified as an embedded massive young stellar object. The spectrum of the latter source can be interpreted by blue-shifted (-3000 ~ -6000km/s) optically-thin emission of the fundamental ro-vibrational transitions (v=1-0) of CO molecules with temperatures of 12000--3700K without noticeable H2 and HI emission. We discuss the nature of this source in terms of outflow associated with the young stellar object and supernova ejecta associated with a supernova remnant.

description: Many physical quantities in solid-state physics are calculated from k-space summation. For spectral functions, the frequency-dependent factor can be decomposed into the energy-conserving delta function part and the nondissipative principal value part. A very useful scheme for this k-space summation is the tetrahedron method. Tetrahedron methods have been widely used to calculate the summation of the energy-conserving delta function part such as the imaginary part of the dielectric function. On the other hand, the corresponding tetrahedron method for the nondissipative part such as the real part of the dielectric function has not been used much. In this paper, we address the technical difficulties in the tetrahedron method for the nondissipative part and present an easy-to-implement, stable method to overcome those difficulties. We demonstrate our method by calculating the static and dynamical spin Hall conductivity of platinum. Our method can be widely applied to calculate linear static or dynamical conductivity, self-energy of an electron, and electric polarizability, to name a few.
