description: The properties of the cosmic microwave background (CMB) temperature and polarisation anisotropies measured by a static, off-centered observer located in a local spherically symmetric void, are described. In particular in this paper we compute, together with the standard 2- point angular correlation functions, the off-diagonal correlators, which are no more vanishing by symmetry. While the energy shift induced by the off-centered position of the observer can be suppressed by a proper choice of the observer velocity, a lensing-like effect on the CMB emission point remains. This latter effect is genuinely geometrical (e.g. non-degenerate with a boost) and reflects in the structure of the off-diagonal correlators. At lowest order in this effect, the temperature and polarisation correlation matrices have non-vanishing diagonal elements, as usual, and all the off-diagonal terms are excited. This particular signature of a local void model allows one, in principle, to disentangle geometrical effects from local kinematical ones in CMB observations.

description: The International Day for the Elimination of Sexual Violence in Conflict provides us with an important opportunity to reflect on this specific form of violence and its distressing prevalence in ongoing conflicts, including the war in Ukraine. Despite persistent efforts towards its elimination undertaken by the United Nations and numerous civil society organizations during the past decades, there remains an urgent need to raise awareness and advocate for survivor-centered preventive measures and responses.
The effect of Service Quality on Customer satisfaction The Case of Ethiopian Revenue & Customs Authority, Nifassilk-Lafto Subcity

description: A lot of work has gone into studying service quality and customer satisfaction in the private sector but a few are conducted in the public sector such as ERCA. Moreover the prevailing indicators of customer dissatisfaction in relation to service delivery at ERCA demand to conduct a study on the issue. This study was conducted to examine the effect of service quality on customer satisfaction in the context of ERCA-Nifassilk-Lafto sub-city. The SERVPERF model was employed and the study was conducted using a quantitative method through cross-sectional survey design. The sample size was 387 and the sampling technique used was convenient sampling. Self administered survey questionnaire based on the modified 22 items of the SERVPERF scale was used as instrument to collect primary data. The results of correlation analysis showed that all the five service quality dimensions were significantly correlated with customer satisfaction. The dimension that was highly correlated with customer satisfaction was empathy (correlation coefficient = 0.807) followed by assurance (correlation coefficient = 0.785), responsiveness (correlation coefficient = 0.784), reliability (correlation coefficient = 0.777), and finally tangibility was found to be the dimension that was least correlated with customer satisfaction (with correlation coefficient = 0.547). Multiple regression analysis was also performed and from the results the R2 value for the model summary of the five service quality dimensions was 0.81 which indicated that service quality dimensions on aggregate are capable of explaining the variance in customer satisfaction by 81%.The 'b' coefficients for tangibility, reliability, empathy, assurance and responsiveness, were found to be 0.082, 0.264, 0.303, 0.291 and 0.271 respectively. Except tangibility the 'b' coefficients for the four service quality dimensions were statistically significant at 99% confidence intervals and for the dimension tangibility it was significant at 95% confidence interval

description: The 2+1d continuum Lifshitz theory of a free compact scalar field plays a prominent role in a variety of quantum systems in condensed matter physics and high energy physics. It is known that in compact space, it has an infinite ground state degeneracy. In order to understand this theory better, we consider two candidate lattice regularizations of it using the modified Villain formalism. We show that these two lattice theories have significantly different global symmetries (including a dipole global symmetry), anomalies, ground state degeneracies, and dualities. In particular, one of them is self-dual. Given these theories and their global symmetries, we can couple them to corresponding gauge theories. These are two different $U(1)$ tensor gauge theories. The resulting models have excitations with restricted mobility, i.e., fractons. Finally, we give an exact lattice realization of the fracton/lineon-elasticity dualities for the Lifshitz theory, scalar and vector charge gauge theories.

description: We propose a scheme to dynamically generate optical flux lattices with nontrivial band topology using amplitude-modulated Raman lasers and radio-frequency (rf) magnetic fields. By tuning the strength of Raman and rf fields, three distinct phases are realized at unit filling for a unit cell. Respectively, these three phases correspond to normal insulator, topological Chern insulator, and semimetal. Nearly nondispersive bands are found to appear in the topological phase, which promises opportunities for investigating strongly correlated quantum states within a simple cold-atom setup. The validity of our proposal is confirmed by comparing the Floquet quasienergies from the evolution operator with the spectrum of the effective Hamiltonian.

A computational study of particle deposition patterns from a circular laminar jet

description: Particle deposition patterns on the plate of inertial impactor with circular laminar jet are investigated numerically with a Lagrangian solver implemented within the framework of the OpenFOAM$^{\circledR}$ CFD package. Effects of taper angle of the nozzle channel and jet-to-plate distance are evaluated. The results show that tapered nozzle tends to deposit more particles toward the circular spot edge than straight nozzle. At jet Reynolds number $Re = 1132$, a tapered nozzle deposits particles to form a pattern with a high density ring toward the deposition spot edge, especially for particle Stokes number $St > St_{50}$, which is absent with a straight nozzle. Increasing the jet-to-plate distance tends to reduce the value of particle density peak near deposition spot edge. Reducing $Re$ to $283$ (e.g., for $300$ ccm flow through a $1.5$ mm diameter jet nozzle) yields particle deposition patterns without the high density ring at the deposition spot edge when the same tapered nozzle is used. The particle deposition patterns with the straight nozzle at $Re = 283$ exhibit further reduced particle density around the spot edge such that the particle density profile appears more or less like a Gaussian function. In general, the effect of reducing $Re$ on particle deposition pattern seems to be similar to increasing the jet-to-plate distance. The computed particle deposition efficiency $η$ shows the fact that very fine particles with extremely small values of $St$ near the jet axis always impact the center of plate, indicating that the value of $η$ does not approach zero with a substantial reduction of $St$. Such a "small particle contamination" typically amounts to $\sim 10\%$ of small particles (with $\sqrt{St} < 0.1$) at $Re \sim 1000$ and $\sim 5\%$ at $Re \sim 300$, which may not be negligible in data analysis with inertial impactor measurement.

description: This work focuses on the microstructure, magnetic properties and magnetocaloric effect of CoFe$_2$O$_4$ (CFO) nanoparticles elaborated by sol-gel auto combustion method. The XRD investigation indicates that CFO is crystallized in a cubic spinel structure and the SEM micrograph shows a fine quasi-spherical with an average grain sizes of 160 nm. The temperature dependence of the Raman spectra reveals the ferromagnetic to paramagnetic (FM-PM) transition started from 723 K and the magnetization versus temperature measurements shows the Curie temperature located at T$_{\rm C}$ = 785 K. Large value of magnetocaloric temperature change of $Δ$T =11.2 K with a high RCP of 687.56 J Kg$^{-1}$ are achieved indirectly via the Maxwell approach making our CFO nanopowder suitable candidate for both environmentally friendly magnetic refrigeration and medical applications at ambient temperature.

description: In this third paper of a series on radio weak lensing for cosmology with the Square Kilometre Array, we scrutinise synergies between cosmic shear measurements in the radio and optical/near-IR bands for mitigating systematic effects. We focus on three main classes of systematics: (i) experimental systematic errors in the observed shear; (ii) signal contamination by intrinsic alignments; and (iii) systematic effects due to an incorrect modelling of non-linear scales. First, we show that a comprehensive, multi-wavelength analysis provides a self-calibration method for experimental systematic effects, only implying <50% increment on the errors on cosmological parameters. We also illustrate how the cross-correlation between radio and optical/near-IR surveys alone is able to remove residual systematics with variance as large as 0.00001, i.e. the same order of magnitude of the cosmological signal. This also opens the possibility of using such a cross-correlation as a means to detect unknown experimental systematics. Secondly, we demonstrate that, thanks to polarisation information, radio weak lensing surveys will be able to mitigate contamination by intrinsic alignments, in a way similar but fully complementary to available self-calibration methods based on position-shear correlations. Lastly, we illustrate how radio weak lensing experiments, reaching higher redshifts than those accessible to optical surveys, will probe dark energy and the growth of cosmic structures in regimes less contaminated by non-linearities in the matter perturbations. For instance, the higher-redshift bins of radio catalogues peak at z~0.8-1, whereas their optical/near-IR counterparts are limited to z<0.5-0.7. This translates into having a cosmological signal 2 to 5 times less contaminated by non-linear perturbations.

description: With increasing competition and quickly spreading of knowledge, the future of many businesses depend upon their ability to innovate. However, empirical and environmental scan evidence shows that low technological innovativeness of small and Medium Enterprises (SMEs) in Addis Ababa. Thus, this study examines barriers for technological innovation in SMEs. The data for the study was collected from four selected sub cities of Addis Ababa SMEs (Akaki, Bole, Kirkos and Yeka). The questionnaires were distributed randomly for 207 SME managers and/or owners to gather the needed information. The data gathered from managers or owners' using ordinary scale was analyzed quantitatively. On the other hand, interview data from official of sub cities was analyzed qualitatively. The mean, mode, percentage, and correlation analyses were used to process variables and data analysis. The result of this study indicates that the major barriers of introducing or expanding technological innovation for the sampled SMEs are: lack of government policy and regulation, lack of technological and market information, inadequate research and development, high cost of innovation, organizational culture, size of enterprise, lack of skilled personnel, lack of finance and absence of cooperation. In addition, the comparative analysis indicate that, except government policy and regulation, organizational culture, size of enterprise and lack of skilled personnel, all other factors were considered to be an important barrier to industry level and both for Small and Medium Enterprises. Similarly, all factors have statistically significant relationship for Industry, Small and Medium specific, except lack of cooperation, it is statistically insignificant for SME's specific technological innovation.

description: Let $P$ be a parabolic subgroup of a connected simply connected complex semisimple Lie group $G$. Given a compact Kähler manifold $X$, the dimensional reduction of $G$-equivariant holomorphic vector bundles over $X\times G/P$ was carried out by the first and third authors. This raises the question of dimensional reduction of holomorphic principal bundles over $X\times G/P$. The method used for equivariant vector bundles does not generalize to principal bundles. In this paper, we adapt to equivariant principal bundles the Tannakian approach of Nori, to describe the dimensional reduction of $G$-equivariant principal bundles over $X\times G/P$, and to establish a Hitchin--Kobayashi type correspondence. In order to be able to apply the Tannakian theory, we need to assume that $X$ is a complex projective manifold.

description: We study the mass-richness relation using galaxy catalogues and images from the Sloan Digital Sky Survey. We use two independent methods, in the first one, we calibrate the scaling relation with weak-lensing mass estimates. In the second procedure we apply a background subtraction technique to derive the probability distribution, $P(M \mid N)$, that groups with $N$-members have a virialized halo mass $M$. Lensing masses are derived in different richness bins for two galaxy systems sets: the maxBCG catalogue and a catalogue based on a group finder algorithm developed by Yang et al. MaxBCG results are used to test the lensing methodology. The lensing mass-richness relation for the Yang et al. group sample shows a good agreement with $P(M \mid N)$ obtained independently with a straightforward procedure.

description: In this paper we present some new results regarding the solvability of nonlinear Hammerstein integral equations in a special cone of continuous functions. The proofs are based on a certain fixed point theorem of Leggett and Williams type. We give an application of the abstract result to prove the existence of nontrivial solutions of a periodic boundary value problem. We also investigate, via a version of Krasnosel{\cprime}slki{\uı}'s theorem for the sum of two operators, the solvability of perturbed Hammerstein integral equations in the space of continuous functions of bounded variation in the sense of Jordan. As an application of these results, we study the solvability of a boundary value problem subject to integral boundary conditions of Riemann--Stieltjes type. Some examples are presented in order to illustrate the obtained results.

description: We prove that prethermalization is a generic property of gapped local many-body quantum systems, subjected to small perturbations, in any spatial dimension. More precisely, let $H_0$ be a Hamiltonian, spatially local in $d$ spatial dimensions, with a gap $Δ$ in the many-body spectrum; let $V$ be a spatially local Hamiltonian consisting of a sum of local terms, each of which is bounded by $ε\ll Δ$. Then, the approximation that quantum dynamics is restricted to the low-energy subspace of $H_0$ is accurate, in the correlation functions of local operators, for stretched exponential time scale $τ\sim \exp[(Δ/ε)^a]$ for any $a<1/(2d-1)$. This result does not depend on whether the perturbation closes the gap. It significantly extends previous rigorous results on prethermalization in models where $H_0$ was frustration-free. We infer the robustness of quantum simulation in low-energy subspaces, the existence of athermal ``scarred" correlation functions in gapped systems subject to generic perturbations, the long lifetime of false vacua in symmetry broken systems, and the robustness of quantum information in non-frustration-free gapped phases with topological order.

Year: 2019

description: Commodity exchanges have crucial roles in the economic development of a nation at large and in the financial and non-financial developments of their market actors. Exporters of commodities as market actors of commodity exchanges are expected to benefit from agricultural commodity exchanges. The purpose of this paper was to examine the role of ECX in stimulating agricultural commodity exports with the case of export coffee. A structured questionnaire was prepared to measure ECX"s role in this regard from its coffee exporting members" perspective. A quantitative research approach was implemented, and the hypotheses were also tested on a sample of 130 coffee exporting members and non-member direct traders of ECX. Out of the 130 distributed questionnaires, valid response was collected from 118 respondents resulting with a 90.77% percent response rate. The data were analyzed using descriptive statistics, correlation & regression. The findings of descriptive statistics of the independent variables showed that facilitation of physical trade dimension scored the highest rating with a mean value of 3.83 while the storage and grading dimension scored the least mean value of 2.86. The correlation analysis result indicated that facilitation of physical trade had significant correlation with the export performance with 95% confidence interval & at 0.05 p-value, by scoring a Pearson Correlation Coefficient "R-value" of 0.665 and the remaining variables" result indicated that they were moderately correlated with export performance. The linear combination of the predictors" (independent variables) explained 54.6% of the variance in export performance. In addition to correlation analysis, further regression analysis was also conducted, and the result indicated that storage and grading, market information provision and market development dimensions of ECX"s roles had a significant positive influence on export performance of coffee exporters. The results are useful to ECX in identifying focus areas of service that help to enhance the performance of coffee exporter members.

description: With increasing commercial availability of quantum information processing devices the need for testing them efficiently for their specified functionality will arise. Complete quantum channel characterization is out of the question for anything more than the simplest quantum channels for one or two qubits. Quantum functional testing leads to a decision problem with outcomes corresponding to rejection or acceptance of the claim of the producer that the device parameters are within certain specifications. In this context, we introduce and analyse three ingredients that can speed up this decision problem: iteration of the channel, efficient decision criteria, and non-greedy adaptive experimental design.

description: Much literature exists about knowledge transfer in general, but very little deals with the link between the micro-perspective of learning in organizations and structural, cultural, and cognitive constraints caused by the organization - particularly with regard to prerequisites of knowledge-transfer within groups in knowledge-based working processes. The main question of this article is: How can knowledge transfer be supported? We exemplify this theoretical question with the help of an investigation we accomplished in German hospitals. The aim of our article is to fill two detected gaps in the existing literature: First we analyze knowledge transfer as a double-sided process of providing and obtaining knowledge. Second we link structural, cultural, and cognitive perspectives together and give a theoretical underpinning of knowledge transfer. We will give empirical evidence from our survey which supports five of our six hypotheses: Possibilities of interaction, organizational culture, and intrinsic motivation are relevant requirements for knowledge transfer. Only team size is not a significant factor for transferring knowledge in hospitals. In detail we show in this article that different factors support providing or obtaining knowledge.

description: Emergence of new protein structures has proved difficult to trace in nature and engineer in the laboratory. However, one aspect of structure evolution has proved immensely helpful for determining the three-dimensional structure of proteins from their sequences: in the vast majority of cases, proteins that share more than 30% sequence identity have similar structures. Below this mark is the "twilight zone" where proteins may have identical or very different structures. These observations form the foundational intuition behind structure homology modeling. Despite their importance, however, they have never received a comprehensive biophysical justification. Here we show that the onset of the twilight zone is more gradual for proteins with low contact density, a proxy for low thermodynamic stability, than proteins with high contact density. Then we present an analytical model that treats divergent fold evolution as an activated process, in analogy to chemical kinetics, where sequence evolution must overcome thermodynamically unstable evolutionary intermediates to discover new folds. This model explains the existence of a twilight zone and explains why its onset is more abrupt for some classes of proteins than for others. We test the assumptions of the model and characterize the dynamics of fold evolution using evolutionary simulations of model proteins and cell populations. Overall these results show how fundamental biophysical constraints directed evolutionary dynamics leading to the Universe of modern protein structures and sequences.

description: In Einstein's General Relativity (GR), the gravitational interactions are described by the spacetime curvature. Recently, other alternative geometric formulations and representations of GR have emerged in which the gravitational interactions are described by the so-called torsion or non-metricity. Here, we consider the recently proposed modified symmetric teleparallel theory of gravity or $f\left( Q\right) $ gravity, where $Q$ represents the non-metricity scalar. In this paper, motivated by several papers in the literature, we assume the power-law form of the function $% f\left( Q\right) $ as $f\left( Q\right) =αQ^{n+1}+β$ (where $% α$, $β$, and $n$ are free model parameters) that contains two models: Linear ($n=0$) and nonlinear ($n\neq 0$). Further, to add constraints to the field equations we assume the deceleration parameter form as a divergence-free parametrization. Then, we discuss the behavior of various cosmographic and cosmological parameters such as the jerk, snap, lerk, $Om$ diagnostic, cosmic energy density, isotropic pressure, and equation of state (EoS) parameter with a check of the violation of the strong energy condition (SEC) to obtain the acceleration phase of the Universe. Hence, we conclude that our cosmological $f(Q)$ models behave like quintessence dark energy (DE).

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Globalization and technology improvements have exposed companies to a situation with tough competition; Banking is one of the service industries characterized by high customer contact with individually customized service solutions where customer satisfaction has been an increasing focus of research (Molina et al., 2007). Customer loyalty is the top 10 most valuable performance measures (Davidson 1999) and is also considered as one of the 15 most commonly used measures according to Ambler and Puntoni (2003).Only few studies have investigated and measured CRM effect despite the practical relevance of operational zing and measuring CRM effect for business performance variables (Padmavathy et al., 2012).The general objective of the study was to investigate the possible relationship between Customer relationship management and customer loyalty in the banking industry in Ethiopia. More specifically, the study tried to see the relationship of CRM with Trust, Commitment, conflict handling, and Communication & Primary data was obtained through structured questionnaire from customers selected banks i.e. CBE and ZB. A convince non probability sampling technique was used to sample between banking firms. The researcher proportionally distributed 294 questionnaires to customers of the two selected banks and 267 of them were good for further analysis. The questionnaires were analyzed using SPSS version 20. Pearson Correlation and multiple regressions were used to establish the relationship between the independent and dependent constructs of the research. The findings revealed that the two independent variables (Conflict handling and Competence) are statistically important determinants of customer loyalty in the banking industry of Ethiopia whereas Commitment, Trust and Communication had positive relation with customer loyalty but not predictor of customer loyalty since they were not supported by the findings. A conclusion was drawn to the effect that since factor influencing customer loyalty have been established, banks should give appropriate focus to significant dimensions of CRM.

description: The thermal spectrum of relic gravitational waves causes the new amplitude that called `modified amplitude'. Our analysis shows that, there exist some chances for detection of the thermal spectrum in addition to the usual spectrum by Adv.LIGO data of GW150914 and detector based on the maser light (Dml). The behavior of the inflation and reheating stages are often known as power law expansion like $ S(η)\propto η^{1+β}$, $S(η)\propto η^{1+β_s}$ respectively. The $β$ and $β_s$ have an unique effect on the shape of the spectrum. We find some upper bounds on the $β$ and $β_s$ by comparison the usual and the thermal spectrum with the Adv.LIGO and Dml. As this result modifies our information about the nature of the evolution of inflation and reheating stages.

Stochastic Relations Interpreting Modal Logic
Creators: name: Doberkat, Ernst-Erich

Year: 2004
Subjects: subject: bisimulations
subject: congruences
subject: Hennessy-Milner Theorem
subject: modallogic
subject: stochastic Kripke models
subject: stochastic relations
subject: 004

description: We propose an interpretation of modal logic through stochastic relations, providing a probabilistic complement to the usual nondeterministic interpretations using Kripke models. A simple temporal logic and a logic with a countable number of diamonds illustrate the approach. The main technical result of this paper is a probabilistic analogon to the well-known Hennessy-Milner Theorem characterizing models that have the same theories for their states and bisimilarity as equivalent properties. This requires the study of congruences for stochastic relations that underly the interpretation, for which a general bisimilarity result is also established. The results depend on the existence of semi-pullbacks for stochastic relations over analytic spaces.
Classes of hydrodynamic and magnetohydrodynamic turbulent decay

description: We perform numerical simulations of decaying hydrodynamic and magnetohydrodynamic turbulence. We classify our time-dependent solutions by their evolutionary tracks in parametric plots between instantaneous scaling exponents. We find distinct classes of solutions evolving along specific trajectories toward points on a line of self-similar solutions. These trajectories are determined by the underlying physics governing individual cases, while the infrared slope of the initial conditions plays only a limited role. In the helical case, even for a scale-invariant initial spectrum (inversely proportional to wavenumber k), the solution evolves along the same trajectory as for a Batchelor spectrum (proportional to k^4.

description: The present work is dedicated to the description of the thin-walled conductor attraction effect by the pulse magnetic field. This phenomenon was displayed experimentally. The effect pointed out relates to the direction of the pulse magnetic fields energy practical usage for the different technologies in manufacture. In the scientific literature this direction is known as the magnetic pulse metal forming. A hypothesis about the physical essence of the displayed phenomenon is suggested.

description: Electronic structure calculations have been instrumental in providing many important insights into a range of physical and chemical properties of various molecular and solid-state systems. Their importance to various fields, including materials science, chemical sciences, computational chemistry and device physics, is underscored by the large fraction of available public supercomputing resources devoted to these calculations. As we enter the exascale era, exciting new opportunities to increase simulation numbers, sizes, and accuracies present themselves. In order to realize these promises, the community of electronic structure software developers will however first have to tackle a number of challenges pertaining to the efficient use of new architectures that will rely heavily on massive parallelism and hardware accelerators. This roadmap provides a broad overview of the state-of-the-art in electronic structure calculations and of the various new directions being pursued by the community. It covers 14 electronic structure codes, presenting their current status, their development priorities over the next five years, and their plans towards tackling the challenges and leveraging the opportunities presented by the advent of exascale computing.

description: We report on the production of ultracold heteronuclear YbLi* molecules in a dual-species magneto-optical trap by photoassociation (PA). The formation of the electronically excited molecules close to dissociation was observed by trap loss spectroscopy. We find 4 rovibrational states within a range of $250\,$GHz below the Yb($^1S_0$) + Li($^2P_{1/2}$) asymptote and observe isotopic PA line shifts in mixtures of $^6$Li with $^{174}$Yb, $^{172}$Yb, and $^{176}$Yb. We also describe our theoretical ab-initio calculation for the relevant electronic potentials and utilize it to analyze and identify the lines in the experimentally observed spectrum.

description: The third string bordism group $\mathrm{Bord}_3^{\mathrm{String}}$ is known to be $\mathbb{Z}/24\mathbb{Z}$. Using Waldorf's notion of a geometric string structure on a manifold, Bunke--Naumann and Redden have exhibited integral formulas involving the Chern-Weil form representative of the first Pontryagin class and the canonical 3-form of a geometric string structure that realize the isomorphism $\mathrm{Bord}_3^{\mathrm{String}} \to \mathbb{Z}/24\mathbb{Z}$. We will show how these formulas naturally emerge when one considers certain natural $\mathrm{U}(1)$-valued and $\mathbb{R}$-valued 3d TQFT associated with the classifying stacks of Spin bundles with connection and of String bundles with geometric structure, respectively.

description: We develop a method to calculate left-right eigenvector correlations of the product of $m$ independent $N\times N$ complex Ginibre matrices. For illustration, we present explicit analytical results for the vector overlap for a couple of examples for small $m$ and $N$. We conjecture that the integrated overlap between left and right eigenvectors is given by the formula $O = 1 + (m/2)(N-1)$ and support this conjecture by analytical and numerical calculations. We derive an analytical expression for the limiting correlation density as $N\rightarrow \infty$ for the product of Ginibre matrices as well as for the product of elliptic matrices. In the latter case, we find that the correlation function is independent of the eccentricities of the elliptic laws.

Historical studies not elsewhere classified

description: After a brief exposition of the work El Imperio de la China, by Jesuit Álvaro Semedo, I examine elements of the elocution of the historical and geographical genres, the moralizing purpose of the 1600s, the relationship of historical discourse with rhetoric and poetics, as well as the understanding of its post-Tridentine evangelizing cause, to understand the possibilities of truth in History.
