description: In this paper, we calculate the scalar $a_0(980)$-meson leading-twist wavefunction by using light-cone harmonic oscillator model (LCHO). In which the model parameters are determined by fitting the $ξ$-moments $\langleξ_{a_0}^n\rangle_ζ$ of its light-cone distribution amplitudes. Then, the $a_0(980)$-meson leading-twist light-cone distribution amplitudes with three different scales $ζ= (1.0, 2.0, 5.2)~{\rm GeV}$ are given. After constructing the relationship between $a_0(980)$-meson leading-twist parton distribution functions/valence quark distribution function and its LCHO wavefunction, we exhibit the $q^{a_0}(x,ζ)$ and $x q^{a_0}(x,ζ)$ with different scales. Furthermore, we also calculate the Mellin moments of the $a_0(980)$-meson's valence quark distribution function $\langle x^n q^{a_0}\rangle_ζ$ with $n = (1,2,3)$, i.e. $\langle x q^{a_0}\rangle_{ζ_5} = 0.026$, $\langle x^2 q^{a_0}\rangle_{ζ_5} = 0.017$ and $\langle x^3 q^{a_0}\rangle_{ζ_5} = 0.012$. Finally, the scale evolution for the ratio of the Mellin moments $x^n_{a_0}(ζ,ζ_k)$ are presented.

description: We theoretically investigate the phenomena of adiabatic quantum charge pumping through a normal-insulator-superconductor-insulator-normal (NISIN) setup of silicene within the scattering matrix formalism. Assuming thin barrier limit, we consider the strength of the two barriers ($χ_{1}$ and $χ_{2}$) as the two pumping parameters in the adiabatic regime. Within this geometry, we obtain crossed Andreev reflection (CAR) with probability unity in the $χ_{1}$-$χ_{2}$ plane without concomitant transmission or elastic cotunneling (CT). Tunability of the band gap at the Dirac point by applying an external electric field perpendicular to the silicene sheet and variation of the chemical potential at the normal silicene region, open up the possibility of achieving perfect either CAR or transmission process through our setup. This resonant behavior is periodic with the barrier strengths. We analyze the behavior of the pumped charge through the NISIN structure as a function of the pumping strength and angles of the incident electrons. We show that large ($Q\sim2e$) pumped charge can be obtained through our geometry when the pumping contour encloses either the CAR or transmission resonance in the pumping parameter space. We discuss possible experimental feasibility of our theoretical predictions.

Determinants of Commercial Banks' Deposit Growth in Ethiopia: Case Study on the Commercial Bank of Ethiopia
Creators: name: Belay, Hibret
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: This study primarily aims at determining the short and long run impacts of determinant factors on deposit growth of commercial bank of Ethiopia for the period 1974/75 to 2013/14 using Vector Error Correction Model (VECM). The study also checked the causal relationships that exist between deposit growth and its determinant factors employing test of Granger causality. In the empirical VECM model, control variables (Economic Growth, Inflation, Interest Rate, Exchange Rate, Population Growth and Branch Expansion) are included to enable ceteris paribus interpretation of the relationship and impact on the growth of deposit in commercial bank of Ethiopia. The estimated results suggest that interest rate has positive but insignificant impact on deposit growth both in the long run and short run. While Exchange rate and branch expansion significantly increases banks deposit contemporaneously both in the short run and long-run. Population and Economic growth also has a positive relationship with deposit growth and it is significant in the long run but insignificant in the short run. However, Inflation has positive and significant impact on deposit in the long-run and negative impact in the short run. Using test of granger causality, the study found uni-directional causality that runs from deposit to inflation, from exchange rate deposit, from deposit to interest rate, from population growth to deposit without any feedback response. The finding also indicates that there is bi-directional causality between branch expansion and deposit and economic growth in Ethiopia. This implies that deposit can affect economic growth through investment. These results have important policy implications for both domestic policy makers and the bankers working in the country. The findings are of direct relevance to the development of deposit mobilization policy by the commercial bank of Ethiopia. KEY WORDS: Deposit, Determinant Factors, VECM, Granger Causality and CBE

description: We study the imprint of light scalar fields on gravitational waves from extreme mass ratio inspirals -- binary systems with a very large mass asymmetry. We first show that, to leading order in the mass ratio, any effects of the scalar on the waveform are captured fully by two parameters: the mass of the scalar and the scalar charge of the secondary compact object. We then use this theory-agnostic framework to show that the future observations by LISA will be able to simultaneously measure both of these parameters with enough accuracy to detect ultra-light scalars.

description: Dynamical reduction models propose a solution to the measurement problem in quantum mechanics: the collapse of the wave function becomes a physical process. We compute the predictions to decaying and Dynamical reduction models propose a solution to the measurement problem in quantum mechanics: the collapse of the wave function becomes a physical process. We compute the predictions to decaying and flavor--oscillating neutral mesons for the two most promising collapse models, the QMUPL (Quantum Mechanics with Universal Position Localization) model and the mass-proportional CSL (Continuous Spontaneous Localization) model. Our results are showing (i) a strong sensitivity to the very assumptions of the noise field underlying those two collapse models and (ii) under particular assumptions the CSL case allows even to recover the decay dynamics. This in turn allows to predict the effective collapse rates solely based on the measured values for the oscillation (mass differences) and the measured values of the decay constants. The four types of neutral mesons ($K$-meson, $D$-meson, $B_d$-meson, $B_s$-meson) lead surprisingly to ranges comparable to those put forward by Adler (2007) and Ghirardi-Rimini-Weber (1986). Our results show that these systems at high energies are very sensitive to possible modifications of the standard quantum theory making them a very powerful laboratory to rule out certain collapse scenarios and studying the detailed physical processes solving the measurement problem.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The study seeks to examine the effects of CBE"s advertising on customers" attitude. To achieve the objective, both primary and secondary data sources were used. In this study, advertisement was treated as an independent variable and customers" attitude was considered as dependent variable. Advertisement was further expressed using specific variables such as celebrity endorsement, message credibility, message attractiveness, media accessibility, media attractiveness and media credibility. Descriptive as well as inferential statistics were used to analyze the data and interpret results. The findings indicate that CBE"s advertising has a positive and significant effects on customers" attitude. Specifically, Celebrity Endorsement, Message Credibility and Media Attractiveness have a positive and significant effect on customers" attitude. Thus, it is important for the bank to continue advertising using a celebrity who has good reputation. In addition, it is advisable for the bank to conduct a media audience survey to select a media which has strong public acceptance before undertaking promotion.

We give a matrix product construction for this ground state and the corresponding symmetric Koornwinder polynomials. Based on the form of this construction and numerical evidence, we conjecture a relation between the generating function of the cumulants of the current, and a certain limit of the symmetric Koornwinder polynomials.

Our model corresponds to an ideal gas performing constantly accelerating motion in a Minkowski spacetime at zero temperature, where the gas is composed of the complex scalar particles, and is supposed to be in a thermal bath at some temperature by the Unruh effect. The critical Unruh temperature we obtain agrees with the usual result in the 4D Euclid space at finite temperature.

Configurational Entropy of Self Propelled Glass Formers

description: The configurational entropy is an indispensable tool to describe super-cooled liquids near the glass transition. Its calculation requires the enumeration of the basins in the potential energy landscape and when available, it reveals a direct connection with the relaxation time of the liquid. While there are several reports on the measurement of configurational entropy in passive liquids, very little is understood about its role in active liquids which have a propensity to undergo a glass transition at low temperatures. In this paper, we report a careful calculation of the configurational entropy in a model glass former where the constituent units are self propelled. We show that unlike passive liquids, the anharmonic contribution to the glass entropy in these self-propelled liquids can be of the same order as the harmonic contribution, and therefore must be included in the calculation of the configurational entropy. Our extracted configurational entropy is in good agreement with the generalized Adam-Gibbs relation predicted by the random first order transition theory enabling us to deduce a scaling relation between the configurational entropy and the point-to-set length scale in these active systems. Our findings could be of great utility in conventional active systems such as self-propelled granules, Janus particles and dense bacterial suspensions, to mention a few.

description: GARCH- and Stochastic Volatility (SV)-models are the main workhorses for describing unobserved volatility in asset returns. Because economic theory behind these models is not the same and estimating SV-models is much more difficult, discriminating between these two rival models is of interest. This paper suggests a nonnested testing procedure going back to Davidson and MacKinnon (1981) that does not implicitly assume that one of the models is the correct one. We illustrate the proposed test by applying it to ten daily stock index return series and five exchange rate return series.

description: In this paper, we establish connections between the first extensions of simple modules and certain filtrations of of standard modules in the setting of graded Hecke algebras. The filtrations involved are radical filtrations and Jantzen filtrations. Our approach involves the use of information from the Langlands classification as well as some deeper understanding on some structure of some modules. Such module arises from the image of a Knapp-Stein type intertwining operator and is a quotient of a generalized standard module. Along the way, we also deduce some results on the blocks for finite-dimensional modules of graded Hecke alebras. As an application, we compute the Ext-groups for irreducible modules in a block for the graded Hecke algebra of type $C_3$, assuming the truth of a version of Jantzen conjecture.

description: Modern privacy regulations, such as the General Data Protection Regulation (GDPR), address privacy in software systems in a technologically agnostic way by mentioning general "technical measures" for data privacy compliance rather than dictating how these should be implemented. An understanding of the concept of technical measures and how exactly these can be handled in practice, however, is not trivial due to its interdisciplinary nature and the necessary technical-legal interactions. We aim to investigate how the concept of technical measures for data privacy compliance is understood in practice as well as the technical-legal interaction intrinsic to the process of implementing those technical measures. We follow a research design that is 1) exploratory in nature, 2) qualitative, and 3) interview-based, with 16 selected privacy professionals in the technical and legal domains. Our results suggest that there is no clear mutual understanding and commonly accepted approach to handling technical measures. Both technical and legal roles are involved in the implementation of such measures. While they still often operate in separate spheres, a predominant opinion amongst the interviewees is to promote more interdisciplinary collaboration. Our empirical findings confirm the need for better interaction between legal and engineering teams when implementing technical measures for data privacy. We posit that interdisciplinary collaboration is paramount to a more complete understanding of technical measures, which currently lacks a mutually accepted notion. Yet, as strongly suggested by our results, there is still a lack of systematic approaches to such interaction. Therefore, the results strengthen our confidence in the need for further investigations into the technical-legal dynamic of data privacy compliance.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2027

description: This study seeks to assess the strategic human resources management practices of Ethiopian private commercial banks. The study adopts a probabilistic research method approach. Specifically, the study adopted the survey method using a population of seven banks and 7,308 employees. The head office of each bank was purposively sampled. A sample of 314 employees was selected using stratified random sampling. Data was collected using self-administered questionnaires and interviews. Data analysis involved statistical computations for averages, percentages, and standard deviation analysis. Statistical computer software (SPSS and MS Excel) were used in data analysis. From the study, it was found that the overall strategic human resource practices in private commercial banks were perceived positively. However, training and development as well as integration of HRM practices with corporate strategy were perceived negatively. From the study, it is concluded that there is a positive perception of overall strategic human resource management practices in private commercial banks. Training programs, participative work settings, impartial recruitment and incentive arrangements provide proper motivation and combine to enhance organizational goals' achievement in terms of market share and profitability. It is recommended that private commercial banks should develop and document human resource management strategies that are linked with the overall banks strategy.

Starting from two spatially separated Bose-Einstein condensates of Rb and Cs atoms, Rb-Cs atom pairs are efficiently produced by using the superfluid-to-Mott insulator quantum phase transition twice, first for the Cs sample, then for the Rb sample, after nulling the Rb-Cs interaction at a Feshbach resonance's zero crossing. We form molecules out of atom pairs and characterize the mixing process in terms of sample overlap and mixing speed. The dense and ultracold sample of more than 5000 RbCs molecules is an ideal starting point for experiments in the context of quantum many-body physics with long-range dipolar interactions.

description: We construct electrically charged Kerr black holes (BHs) with scalar hair. Firstly, we take an uncharged scalar field, interacting with the electromagnetic field only indirectly, via the background metric. The corresponding family of solutions, dubbed Kerr-Newman BHs with ungauged scalar hair, reduces to (a sub-family of) Kerr-Newman BHs in the limit of vanishing scalar hair and to uncharged rotating boson stars in the limit of vanishing horizon. It adds one extra parameter to the uncharged solutions: the total electric charge. This leading electromagnetic multipole moment is unaffected by the scalar hair and can be computed by using Gauss's law on any closed 2-surface surrounding (a spatial section of) the event horizon. By contrast, the first sub-leading electromagnetic multipole -- the magnetic dipole moment --, gets suppressed by the scalar hair, such that the gyromagnetic ratio is always smaller than the Kerr-Newman value ($g=2$). Secondly, we consider a gauged scalar field and obtain a family of Kerr-Newman BHs with gauged scalar hair. The electrically charged scalar field now stores a part of the total electric charge, which can only be computed by applying Gauss' law at spatial infinity and introduces a new solitonic limit -- electrically charged rotating boson stars. In both cases, we analyse some physical properties of the solutions.

Salt fingering staircases and the three-component Phillips effect

description: Understanding the dynamics of staircases in salt fingering convection presents a long-standing theoretical challenge to fluid dynamicists. Although there has been significant progress, particularly through numerical simulations, there are a number of conflicting theoretical explanations as to the driving mechanism underlying staircase formation. The Phillips effect proposes that layering in stirred stratified flow is due to an antidiffusive process, and it has been suggested that this mechanism may also be responsible for salt fingering staircases. However, the details of this process, as well as mathematical models to predict the evolution and merger dynamics of staircases, have yet to be developed. We generalise the theory of the Phillips effect to a three-component system (e.g. temperature, salinity, energy) and demonstrate the first regularised nonlinear model of layering based on mixing-length parameterisations. The model predicts both the inception of layering and its long-term evolution through mergers , whilst generalising, and remaining consistent with, previous results for double-diffusive layering based on flux ratios. Our model of salt fingering is formulated using spatial averaging processes and closed by a mixing length parameterised in terms of the kinetic energy and the salt and temperature gradients. The model predicts a layering instability for a bounded range of parameter values in the salt fingering regime. Nonlinear solutions show that an initially unstable linear buoyancy gradient develops into layers, which merge through a process of stronger interfaces growing at the expense of weaker interfaces. Mergers increase the buoyancy gradient across interfaces, and increase the buoyancy flux through the staircase.

description: In this paper we continue our study of bifurcations of solutions of boundary-value problems for symplectic maps arising as Hamiltonian diffeomorphisms. These have been shown to be connected to catastrophe theory via generating functions and ordinary and reversal phase space symmetries have been considered. Here we present a convenient, coordinate free framework to analyse separated Lagrangian boundary value problems which include classical Dirichlet, Neumann and Robin boundary value problems. The framework is then used to {prove the existence of obstructions arising from} conformal symplectic symmetries on the bifurcation behaviour of solutions to Hamiltonian boundary value problems. Under non-degeneracy conditions, a group action by conformal symplectic symmetries has the effect that the flow map cannot degenerate in a direction which is tangential to the action. This imposes restrictions on which singularities can occur in boundary value problems. Our results generalise classical results about conjugate loci on Riemannian manifolds to a large class of Hamiltonian boundary value problems with, for example, scaling symmetries.

description: In view of the latest experimental results recently released by the ATOMKI collaboration, we critically re-examine the possible theoretical interpretation of the observed anomalies in terms of a new BSM boson $X$ with mass $\sim17\;$MeV. To this end we employ a multipole expansion method and give an estimate for the range of values of the nucleon couplings to the new light state in order to match the experimental observations. Our conclusions identify the axial vector state as the most promising candidate, while other spin/parity assignments seems disfavored for a combined explanation. This results is however based on an order of magnitude estimate for the, currently unknown, axial nuclear matrix element of the $^{12}$C transition, that needs then to be evaluated before being able to draw a definite conclusion. Intriguingly, an axial vector state can also simultaneously accommodate other experimental anomalies, {\emph{i.e.}} the KTeV anomaly in $π^0 \to e^+ e^-$ decay while being compatible with the conflicting measurements of the anomalous magnetic moment of the electron $(g-2)_e$ and other constraints on the electron couplings of the $X$ boson. The PADME experiment will completely cover the relevant region of the parameter space, thus allowing for a strong test of the existence of the $X$ particle.

description: The purpose of this study was to empirically investigate the effect of competitive intelligence on Marketing Effectiveness in the steel manufacturing Industries in Ethiopia. It followed a deductive form of research approach and the research design was explanatory. The target population of this study is seventeen steel/rebar manufacturing industries in Ethiopia. Since, my study is organization based, key informants from the seventeen industries in Ethiopia constituted the study. The two key informants are: Marketing managers, and sales managers, giving a total of thirty four respondents who were administered the copies of the questionnaire. Upon retrieval and data cleaning, 30 copies were subjected to Data analysis. Data analyses were aided by the use of SPSS version 21.0. In this research competitive intelligence is diffused in to sub variables which all combine to make competitive intelligence. The sub variables include market place opportunities, competitor threats, competitive risks, core assumptions and vulnerabilities. The data were analyzed using descriptive statistics (frequency, percentage) and inferential statistics like correlation and multiple regressions. The finding revealed that there are positive and significant relationships between market place opportunities & core assumptions as dimensions of competitive intelligence with customer philosophy(Marketing effectiveness), and there is a positive and significant relationship between market place opportunities with competitive risks and core assumptions. Eventually, this study recommends appropriate actions for companies in using competitive intelligence as a means of overcoming the intense competition that exist in the market, and be effective in their marketing

Overall, the tourism industry in Bahir Dar City has shown encouraging and positive growth in the recent days.However, the city administration has to expand and improve transportation and communication facilities and related infrastructures to increase the tourism competitiveness of the city. Furthermore, political stability of the city together with tourists' safety has great impact on tourism development of the city. The research also shows that there should be more encouraging incentive packages to draw tourism investors in the city where tourist attractions are located

description: We study the relation between critical exponents and Hausdorff dimensions of limit sets for projective Anosov representations. We prove that the Hausdorff dimension of the symmetric limit set in $\mathbf{P}(\mathbb{R}^{n}) \times \mathbf{P}({\mathbb{R}^{n}}^*)$ is bounded between two critical exponents associated respectively to a highest weight and a simple root.

Temperature-Dependent Band Structure of SrTiO$_3$ Interfaces

description: We build a theoretical model for the electronic properties of the two-dimensional (2D) electron gas that forms at the interface between insulating SrTiO$_3$ and a number of polar cap layers, including LaTiO$_3$, LaAlO$_3$, and GdTiO$_3$. The model treats conduction electrons within a tight-binding approximation, and the dielectric polarization via a Landau-Devonshire free energy that incorporates strontium titanate's strongly nonlinear, nonlocal, and temperature-dependent dielectric response. The self-consistent band structure comprises a mix of quantum 2D states that are tightly bound to the interface, and quasi-three-dimensional (3D) states that extend hundreds of unit cells into the SrTiO$_3$ substrate. We find that there is a substantial shift of electrons away from the interface into the 3D tails as temperature is lowered from 300 K to 10 K. This shift is least important at high electron densities ($\sim 10^{14}$ cm$^{-2}$), but becomes substantial at low densities; for example, the total electron density within 4~nm of the interface changes by a factor of two for 2D electron densities $\sim 10^{13}$ cm$^{-2}$. We speculate that the quasi-3D tails form the low-density high-mobility component of the interfacial electron gas that is widely inferred from magnetoresistance measurements.

description: FASER, the ForwArd Search ExpeRiment, is a currently operating experiment at the Large Hadron Collider (LHC) that can detect light long-lived particles produced in the forward region of the LHC interacting point. In this paper, we study the prospect of detecting light CP-even and CP-odd scalars at FASER and FASER 2. Considering a model-independent framework describing the most general interactions between a CP-even or CP-odd scalar and SM particles using the notation of coupling modifiers in the effective Lagrangian, we develop the general formalism for the scalar production and decay. We then analyze the FASER and FASER 2 reaches of light scalars in the large $\tanβ$ region of the Type-I two Higgs double model as a case study, in which light scalars with relatively long lifetime could be accommodated. In the two benchmark scenarios we considered, the light (pseudo)scalar decay length varies in $(10^{-8}, 10^5)$ meters. Both FASER and FASER 2 can probe a large part of the parameter space in the large $\tanβ$ region up to $10^5$, extending beyond the constraints of the other existing experiments.

Corporate Governance Mechanisms and Financial Performance in Ethiopian Insurance Industry
Creators: name: Mekonnen, Bedilu

description: Good corporate governance is an important pillar of the market economy and it enhances investor confidence. A strong and balanced board of directors is necessary as a supervising body for the executive management of a company with dispersed ownership and it has received new urgency due to various corporate scandals and failure. This study seeks to see impacts of corporate governance mechanism on financial performance of Insurers in Ethiopia. To address the research hypotheses needs and achieve the broad research objective, a quantitative research approach and explanatory research design were adopted in carrying out this research. The variables were chosen based on findings from both empirical and theoretical literature. Secondary data of seven insurers from 2006 to 2015 with a total of 70 observations were collected using purposive sampling technique. The study employed panel data estimation techniques and the researcher has adopted fixed effects regression technique instead of random effect models, in the case of cross section-fixed effects, the p-value is insignificant and only period fixed effects is allowed to analyse. The study analyses a range of internal corporate governance variables board size, chief executive's compensation, board member educational qualification, female directors in the board, frequency of board meeting, board member other business managements experience, board member's industry specific experience and the study also controls the effect of premium growth of Insurers. The regression results show that, board size, chief executive's compensation, board member educational qualification, female directors in the board, frequency of board meeting, and board member other business managements experience, had a significant effect on the financial performance in Ethiopian insurance sector. Other variables including board member's industry specific experience and premium growth have statistically insignificant impact on financial performance (ROA) of insurance companies in Ethiopia. So, stakeholders should give consideration to board size, chief executive's compensation, board member educational qualification, female directors in the board, frequency of board meeting, and board member other business managements experience when they set governance policy for industry as general and for the company specifically.

Large-Scale Cosmic-Ray Anisotropy as a Probe of Interstellar Turbulence

description: We calculate the large-scale cosmic-ray (CR) anisotropies predicted for a range of Goldreich-Sridhar (GS) and isotropic models of interstellar turbulence, and compare them with IceTop data. In general, the predicted CR anisotropy is not a pure dipole; the cold spots reported at 400 TeV and 2 PeV are consistent with a GS model that contains a smooth deficit of parallel-propagating waves and a broad resonance function, though some other possibilities cannot, as yet, be ruled out. In particular, isotropic fast magnetosonic wave turbulence can match the observations at high energy, but cannot accommodate an energy dependence in the shape of the CR anisotropy. Our findings suggest that improved data on the large-scale CR anisotropy could provide a valuable probe of the properties - notably the power-spectrum - of the interstellar turbulence within a few tens of parsecs from Earth.

description: We present a comprehensive simulation study of the Newtonian and quantum model of a Stern-Gerlach experiment with cold neutrons.By solving Newton's equation of motion and the time-dependent Pauli equation, for a wide range of uniform magnetic field strengths, we scrutinize the role of the latter for drawing the conclusion that the magnetic moment of the neutron is quantized. We then demonstrate that a marginal modification of the Newtonian model suffices to construct, without invoking any concept of quantum theory, an event-based subquantum model that eliminates the shortcomings of the classical model and yields results that are in qualitative agreement with experiment and quantum theory. In this event-by-event model, the intrinsic angular momentum can take any value on the sphere, yet, for a sufficiently strong uniform magnetic field, the particle beam splits in two, exactly as in experiment and in concert with quantum theory.
