description: Whether in nature exists Majorana neutrino is one of the most fundamental questions in physics. It is directly related to the violation of accidental $U(1)$-lepton number symmetry(LNV). Enormous efforts had been put into such test and among them, one conventional experiment is the neutrinoless double-beta decay ($0νββ$). On the other hand, there have been proposals of future electron-positron colliders such as International Linear Collider (ILC) for precision measurements of Higgs boson or new discovered beyond SM particles and it can potentially be converted into an electron-electron collider. Such collider enables a new probe of Majorana neutrino via the inverse $0νββ$ process($e^{-}e^{-}\to W^- W^-$) as an alternative and complementary test to the conventional neutrinoless double-beta decay experiments. In this paper, we illustrate the searching strategies of $e^{-}e^{-}\to W^- W^-$ at future electron colliders, and find that the channels of pure hadronic, semi-leptonic with muon and pure leptonic with muons have the most discovery potential.

description: This paper presents a study of the chemical compositions in cool gas around a sample of 27 intermediate-redshift galaxies. The sample comprises 13 massive quiescent galaxies at z=0.40-0.73 probed by QSO sightlines at projected distances d=3-400 kpc, and 14 star-forming galaxies at z=0.10-1.24 probed by QSO sightlines at d=8-163 kpc. The main goal of this study is to examine the radial profiles of the gas-phase Fe/α ratio in galaxy halos based on the observed Fe II to Mg II column density ratios. Because Mg+ and Fe+ share similar ionization potentials, the relative ionization correction is small in moderately ionized gas and the observed ionic abundance ratio N(Fe II)/N(Mg II) places a lower limit to the underlying (Fe/Mg) elemental abundance ratio. For quiescent galaxies, a median and dispersion of log =-0.06+/-0.15 is found at d ~100 kpc. On the other hand, star-forming galaxies exhibit log =-0.25+/-0.21 at d =-0.9+/-0.4 at larger distances. Including possible differential dust depletion or ionization correction would only increase the inferred (Fe/Mg) ratio. The observed N(FeII)/N(Mg II) implies super-solar Fe/α ratios in the inner halo of quiescent galaxies. An enhanced Fe abundance indicates a substantial contribution by Type Ia supernovae in the chemical enrichment, which is at least comparable to what is observed in the solar neighborhood or in intracluster media but differs from young star-forming regions. In the outer halos of quiescent galaxies and in halos around star-forming galaxies, however, the observed N(Fe II)/N(Mg II) is consistent with an α-element enhanced enrichment pattern, suggesting a core-collapse supernovae dominated enrichment history.

Year: 2017

description: This study attempts to evaluate job satisfaction of bank employees in Commercial Bank of Ethiopia (CBE) and Dashen Bank (DB). It focuses on the relative importance of job satisfaction factors and their impacts on the overall job satisfaction of employees, and also it tried to fill the gap by empirically testing the variables including Pay, Promotion, Supervision, Fringe Benefit, Contingent Reward, Operating Procedure, Co-worker, Nature of work, and Communications on employees job satisfaction. It is a cross sectional case study by using survey data collection method. A quantitative methodology was used and questionnaires were used as measuring instrument. The result has been analyzed in terms of descriptive statistic followed by inferential statistic on the variables. The result indicated that there is a significant and positive relationship between all of independent variables and dependent variables. The present study highlighted the various dimensions necessary for motivating employees to improve the quality of service in the bank sector. Findings showed that DB bank employees have more job satisfaction than CBE employees. The study setting comprised only two banks, one private bank and one public bank; future study could include other private banks so that results could be generalized widely.

description: The present investigation reports the design and synthesis of three series of benzoylthioureido derivatives bearing either benzenesulfonamide 7a–f, benzoic acid 8a–f or ethylbenzoate 9a–f moieties. The synthesised compounds were screened for their carbonic anhydrase inhibitory activity (CAI) against four isoforms hCA I, II, IX, and XII. Compounds 7a, 7b, 7c, and 7f exhibited a potent inhibitory activity towards hCAI (Kis = 58.20, 56.30, 33.00, and 43.00 nM), respectively compared to acetazolamide (AAZ) and SLC-0111 (Kis = 250.00 and 5080.00 nM). Compounds 7a, 7b, 7c, 7e, and 7f elicited selectivity over h CA II (Kis = 2.50, 2.10, 56.60,39.60 and 39.00 nM) respectively, relative to AAZ and SLC-0111(Kis = 12.10 and 960.00 nM). Also, compounds 7c, 7f, and 9e displayed selectivity against the tumour-associated isoform hCA IX (Kis = 31.20, 30.00 and 29.00 nM) respectively, compared to AAZ and SLC-0111 (Kis = 25.70 and 45.00 nM). Additionally, compounds 8a and 8f revealed a moderate to superior selectivity towards hCAXII (Kis = 17.00 and 11.00 nM) relative to AAZ and SLC-0111(Kis = 5.70 and 45.00 nM). Molecular docking and ADME prediction studies were performed on the most active compounds to shed light on their interaction with the hot spots of the active site of CA isoforms, in addition to prediction of their pharmacokinetic and physicochemical properties.

description: We present a method for the evaluation of time-dependent linear response functions for systems of active Ornstein-Uhlenbeck particles from unperturbed simulations. The method is inspired by the Malliavin weights sampling method proposed by Warren and Allen [Phys. Rev. Lett. 109, 250601 (2012)] for systems of Brownian particles. We illustrate our method by evaluating a linear response function for a single active particle in an external harmonic potential. As an application, we calculate the time-dependent mobility function and an effective temperature, defined through the Einstein relation between the self-diffusion and mobility coefficients, for a system of active particles interacting via a screened-Coulomb potential. We find that this effective temperature decreases with increasing persistence time of the self-propulsion. Initially, for not too large persistence times, it changes rather slowly, but then it decreases markedly when the persistence length of the self-propelled motion becomes comparable with the particle size.

description: The quality of language that children hear in their environment is associated with the development of language-related brain regions, in turn promoting vocabulary knowledge. Although informative, it remains unknown how these environmental influences alter the structure of neural tissue and subsequent vocabulary outcomes. The current study uses magnetic resonance elastography (MRE) to examine how children’s language environments underlie brain tissue mechanical properties, characterized as brain tissue stiffness and damping ratio, and promote vocabulary knowledge. Twenty-five children, ages 5–7, had their audio and video recorded while engaging in a play session with their parents. Children also completed the Picture Vocabulary Task (from NIH Toolbox) and participated in an MRI, where MRE and anatomical images were acquired. Higher quality input was associated with greater stiffness in the bilateral inferior frontal gyrus and right superior temporal gyrus, whereas greater vocabulary knowledge was associated with lower damping ratio in the right inferior frontal gyrus. These findings suggest changes in neural tissue composition are sensitive to malleable aspects of the environment, whereas tissue organization is more strongly associated with vocabulary outcome. Notably, these associations were independent of maternal education, suggesting more proximal measures of a child’s environment may be the source of differences in neural tissue structure underlying variability in vocabulary outcomes.

description: Aminoacyl derivatives of aminoadamantanes amantadine and rimantadine have been investigated in regard to their antiviral properties. So far, few studies on the mass spectrometric fragmentation pathway of these compounds have been reported using high-resolution mass spectrometry (HRMS). Two major fragmentation pathways have been observed. For the rimantadine derivatives, losses of rimantadine and N-(1-adamantyl) ethylformamide were described. Similarly, in case of amantadine derivatives, there were losses of amantadine and N-(1-adamantyl) formamide. The loss of the aminoacyl group was common to all of the studied compounds. Understanding the fragmentation mechanism can bring new insight into the characterization of these compounds.

description: Transition probability calculations of strong field particle processes in the Furry picture, typically use fermion Volkov solutions. These solutions have a relatively complicated spinor due to the interaction of the electron spin with a strong external field, which in turn leads to unwieldy trace calculations. The simplification of these calculations would aid theoretical studies of strong field phenomena such as the predicted resonance behaviour of higher order Furry picture processes. Here, Fierz transformations of Volkov spinors are developed and applied to a 1st order and a 2nd order Furry picture process. Combined with symmetry properties, the techniques presented here are generally applicable and lead to considerable simplification of Furry picture analytic calculations.

description: The capacities of Pleurotus ostreatus mushroom and spent substrate were evaluated for the biosorption of cadmium (II) from aqueous solution in order to select the most efficient material for bioremediation. The optimum sorption conditions were optimized, including the pH of the aqueous solution, contact time, biomass dosage, initial metal concentration, and temperature. The sorption of cadmium on both biosorbents was also evaluated by several kinetic, equilibrium, and thermodynamic models. The possible heavy metal biosorption mechanisms were evaluated through point of zero charge (pHpzc), Fourier-transform infrared (FTIR) spectroscopy and scanning electron microscopy coupled with energy dispersive X-ray microanalysis (SEM-EDX). Based on the results of column studies, the effectiveness of the P. ostreatus spent substrate was confirmed as a biosorbent for Cd(II) removal from aqueous solutions.

description: We consider spin chain families inspired by the Su, Schrieffer and Hegger (SSH) model. We demonstrate explicitly the topologically induced spatial localisation of quantum states in our systems. We present detailed investigations of the effects of random noise, showing that these topologically protected states are very robust against this type of perturbation. Systems with such topological robustness are clearly good candidates for quantum information tasks and we discuss some potential applications. Thus, we present interesting spin chain models which show promising applications for quantum devices.

description: A new procedure for the preconcentration of trace amounts of free Pb and Cd by disposable pipette extraction (DPX) is proposed herein. Recycled cork is used as a biosorbent and the procedure is completely free of organic solvents. The cork was reduced to a powder and characterized by scanning electron microscopy. Several parameters that influence the preconcentration of Pb and Cd with DPX-cork, such as the sample pH, number of extraction cycles, biosorbent mass, and percentage of acid in the desorption step, were studied. The tolerance of DPX-cork with respect to 10 potential interfering ions was also evaluated. Coupled with the high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS) technique, the sample preparation method allowed the analytical limits required for quality control (according to the permitted limits established by legislation) to be obtained. The limits of detection for the extraction of a 3.5-mL water sample were 200 ng L−1 for Pb and 100 ng L−1 for Cd. The relative standard deviations were around 7.5% for Pb and 8.0% for Cd. The optimized method was successfully applied to the determination of Cd and Pb in two certified reference materials (water and wastewater) and five water samples (collected from a mangrove, a creek, and the sea).

description: The solution of Boltzmann equation for plasma in magnetic field, with arbitrarily degenerate electrons and non-degenerate nuclei, is obtained by Chapman-Enskog method. Functions, generalizing Sonin polynomials are used for obtaining an approximate solution. Fully ionized plasma is considered. The tensor of the heat conductivity coefficients in non-quantized magnetic field is calculated. For non-degenerate and strongly degenerate plasma the asymptotic analytic formulas are obtained, which are compared with results of previous authors. The Lorentz approximation, with neglecting of electron-electron encounters, is asymptotically exact for strongly degenerate plasma. We obtain, for the first time, in three polynomial approximation, with account of electron-electron collisions, analytical expressions for the heat conductivity tensor for non-degenerate electrons, in presence of a magnetic field. Account of the third polynomial improved substantially the precision of results. In two polynomial approximation our solution coincides with the published results. For strongly degenerate electrons we obtain, for the first time, an asymptotically exact analytical solution for the heat conductivity tensor in presence of a magnetic field. This solution has considerably more complicated dependence on the magnetic field than those in previous publications, and gives several times smaller relative value of a thermal conductivity across the magnetic field at $ωτ\gtrsim 0.8$.

description: This paper proposes a new strategy for missile attitude control using a hybridization of Linear Quadratic Gaussian (LQG), Loop Transfer Recovery (LTR), and Linear Quadratic Integral (LQI) control techniques. The LQG control design is carried out in two steps i.e. firstly applying Kalman filter for state estimation in noisy environment and then using the estimated states for an optimal state feedback control via Linear Quadratic Regulator (LQR). As further steps of performance improvement of the missile attitude control system, the LTR and LQI schemes are applied to increase the stability margins and guarantee set-point tracking performance respectively, while also preserving the optimality of the LQG. The weighting matrix (Q) and weighting factor (R) of LQG and the LTR fictitious noise coefficient (q) are tuned using Nelder-Mead Simplex optimization technique to make the closed-loop system act faster. Simulations are given to illustrate the validity of the proposed technique.

description: A gold (Au) nanoparticle-modified graphite pencil electrode was prepared by an electrodeposition procedure for the sensitive and rapid flow injection amperometric determination of hydrazine (N2H4). The electrodeposited Au nanoparticles on the pretreated graphite pencil electrode surface were characterized by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction spectroscopy, and electrochemical impedance spectroscopy. Cyclic voltammograms showed that the Au nanoparticle-modified pretreated graphite pencil electrode exhibits excellent electrocatalytic activity toward oxidation of hydrazine because the highly irreversibly and broadly observed oxidation peak at +600 mV at the pretreated graphite pencil electrode shifted to −167 mV at the Au nanoparticle pretreated graphite pencil electrode; in addition, a significant enhancement in the oxidation peak current was obtained. Thus, the flow-injection (FI) amperometric hydrazine sensor was constructed based on its electrocatalytic oxidation at the Au nanoparticle-modified pretreated graphite pencil electrode. The Au nanoparticle-modified pretreated graphite pencil electrode exhibits a linear calibration curve between the flow injection amperometric current and hydrazine concentration within the concentration range from 0.01 to 100 µM with a detection limit of 0.002 µM. The flow injection amperometric sensor has been successfully used for the determination of N2H4 in water samples with good accuracy and precision.

description: For two-person dynamic zero-sum games (both discrete and continuous settings), we investigate the limit of value functions of finite horizon games with long run average cost as the time horizon tends to infinity and the limit of value functions of $λ$-discounted games as the discount tends to zero. We prove that the Dynamic Programming Principle for value functions directly leads to the Tauberian Theorem---that the existence of a uniform limit of the value functions for one of the families implies that the other one also uniformly converges to the same limit. No assumptions on strategies are necessary. To this end, we consider a mapping that takes each payoff to the corresponding value function and preserves the sub- and super- optimality principles (the Dynamic Programming Principle). With their aid, we obtain certain inequalities on asymptotics of sub- and super- solutions, which lead to the Tauberian Theorem. In particular, we consider the case of differential games without relying on the existence of the saddle point; a very simple stochastic game model is also considered.
An Assessment of Challenges and Prospects of Foreign Direct Investment in Agricultural Sector in Ethiopia (With Reference to Foreign Investment in Large Scale Farmland)
Creators: name: Aman, Mustafa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: It is obvious that our country has engaged in farmland deal with foreign agricultural investors. The government is leasing tenth of thousands of hectors of farmland to foreign agricultural firms. Therefore, this study is done with the main objective of examining the major benefits and as well threats of foreign investment in large scale farmland in Ethiopia. Thus, this paper has attempted to explore the challenges that made difficult for the country to easily drive the due benefits from foreign investment in large scale farmland. To this end the study collected primary source of data from concerned government authorities and as well from assessed foreign agricultural firm. Secondary sources of data were also used in addition to the primary data gathered. The study has found that there are various obstacles that have challenged the government from driving the due benefits from the contracts of large scale farmland. For instance the issue of transparency and consultation with local farmers and community can be mentioned among many others. The profitability of any foreign investment to a given host country depends on that respective country's government role, that makes it beneficiary to the host country or misery to that host country. Therefore, the study was concluded by recommending certain necessary suggestions, that may enables the government to get a due benefits from large scale farmland deal and consequently address some challenges that hampered the process of the deal and thus strengthen the prospects of foreign investment in large scale farmland
Meritocracy vs. Elitism in Ethiopian Civil Service: the Case of three (3) Selected Federal Ministries
Creators: name: Gebrehiwot, Kidane

description: The purpose of this study is to assess the status of merit based recruitment and the dimension of elitism in the Ethiopian Civil Service system and their impacts on organizational performance in the case of Ministry of Civil Service, Ministry of Trade and the Ministry of Information and Communications Technology. In light of this, using qualitative approach, primary data collected through questionnaires administered and interviews conducted with secondary data from government documents, reports and proclamations reviews were used to make the paper sound. This study is limited to status of meritocracy and dimensions of elitism in the selected 3(three) federal ministries. In these ministry organizations, there are about 749 employees with the exception of security personnel, drivers and janitors. These are selected as target population for the study and using simple random sampling, 75 people (10% of the population) were selected to fill descriptive questionnaires [out of which only 69(92%) of them completed and returned these questionnaires]. Moreover using purposive non-probability sampling, 8 respondents of top management officials from the selected federal ministries and 8 key informants from political parties, scholars and practitioners in the civil service were conducted for interview. The collected data has been analyzed qualitatively and quantitatively using statements, tables and percentages. Survey findings and document analysis show that the Ethiopian civil service has clearly stated rules calling for merit based appointment. However key informants and questionnaire respondents revealed that, practically political membership and loyalty is given weight for advertized civil service jobs. Key informants also revealed that the ruling party EPRDF has established its own network throughout the civil service system to control the civil service for its own purpose. Document analysis and key informant interview showed that, staff appraisal is most of the time not based on competence to jobs. Furthermore key informant interview and questionnaire responses revealed that, some of the political elites fused in the civil service system are less competent. Survey finding also revealed that, political dominance in the civil service system is posing impediments for the organizational performance in the selected federal ministries. The researcher has concluded that merit based recruitment, promotion, transfer and remunerations are weakly practiced. There is high dominance of political elites in the civil service. These all negatively affect organizational performance in the selected federal ministries and the Ethiopian civil service in general. The researcher has finally recommended that, recruitment should be only merit based; political interference should be avoided from the civil service

description: Na pandemia causada pelo vírus Covid-19, muitas escolas públicas estão mantendo aulas de forma remota. No entanto, nem todos os professores estavam preparados para a utilização massiva de ferramentas digitais no processo de ensino-aprendizagem. Sabe-se que é extremamente importante a capacitação profissional de educadores, pois mesmo que as escolas públicas invistam em uma infraestrutura moderna e tecnológica, se a capacitação docente não ocorrer, a intermediação entre o recurso e o aluno será falha. Mesmo em tempos sem pandemia, com uma educação mais tecnológica e atrativa aos estudantes, intermediada pelos educadores, será possível uma maior aceitação e inclusão na recepção de conhecimento por parte dos alunos de diferentes faixas etárias. Este trabalho tem como objetivo principal discutir as experiências relatadas a partir da análise dos dois cursos de capacitação de docentes em tecnologias digitais em educação realizadas pelo IFTM Campus Patrocínio.

description: A thiourea-detecting fluorescence sensor with Hg2+ as a switch was developed using nitrogen-doped graphene quantum dots (N-GQDs). The surface of N-GQDs had many organic functional groups on which Hg2+ was effectively bound and turned off the fluorescence of the N-GQDs. The fluorescence of N-GQDs was turned on by the thiol functional group of thiourea that bound strongly with Hg2+ and formed Hg2+/thiourea complexes. After constructing the sensor, the experimental conditions and parameters, such as the pH and Hg2+ concentration, were investigated and optimized. Under the optimum conditions, the constructed fluorescence sensor showed high sensitivity to thiourea at concentrations from 0.5 to 14 µM with a low detection limit of 41.7 nM. The sensor also exhibited high specificity, excellent stability, and good reproducibility so that the determination of thiourea in various samples had acceptable values with good recoveries from 99% to 106%. The relative standard deviation was less than 4.1% (n = 3).

Impacts of dark energy on weighing neutrinos: mass hierarchies considered

description: Taking into account the mass splittings between three active neutrinos, we investigate impacts of dark energy on constraining the total neutrino mass $\sum m_ν$ by using recent cosmological observations. We consider two typical dark energy models, namely, the $w$CDM model and the holographic dark energy (HDE) model, which both have an additional free parameter compared with the $Λ$CDM model. We employ the Planck 2015 data of CMB temperature and polarization anisotropies, combined with low-redshift measurements on BAO distance scales, type Ia supernovae, Hubble constant, and Planck lensing. Compared to the $Λ$CDM model, our study shows that the upper limit on $\sum m_ν$ becomes much looser in the $w$CDM model while much tighter in the HDE model. In the HDE model, we obtain the $95\%$ CL upper limit $\sum m_ν<0.105~\textrm{eV}$ for three degenerate neutrinos. This might be the most stringent constraint on $\sum m_ν$ by far and is almost on the verge of diagnosing the neutrino mass hierachies in the HDE model. However, the difference of $χ^2$ is still not significant enough to distinguish the neutrino mass hierarchies, even though the minimal $χ^2$ of the normal hierarchy is slightly smaller than that of the inverted hierarchy.

The Role of EDC in creating a suitable environment to start-up women-owned MSEs in Addis Ababa

Year: 2018

description: This research aims to identify the role of EDC in creating suitable environment for start-up women-owned Micro and Small Enterprises in Addis Ababa, and assess EDC's contributions towards filling the skill gaps and the financial problems that most women-owned MSEs face at the start-up stage. Data were gathered distributing questionnaires and an in-depth interview made with key informants. From a total of 104 ETW and WET women trainees at EDC in 2014, a sample size of 83 is taken using simple random sampling method. As per the findings of the study, EDC's role towards skill development and change in entrepreneurial mindset is found to be beneficial to those women trainees. The partnership that EDC has created with Enat Bank is found to be another way of creating an enabling environment to those women owned MSEs because even though low in number, about 18 women with low income trained at EDC have benefited from the collateral free loan and 139 are in waiting list applying for the loan. The fact that those trained women gained new skills and knowledge relevant to running and creating a business; increased their motivation and self-confidence in their entrepreneurial abilities, and are able to employ more employees and increased their capital/total asset is found to be a positive result, the training alone may not guarantee for the achievement of the objectives of the programs of EDC, unless a joint post-training follow-up and strengthened advisory services, more access to credit and working premises, creating a market linkage and other supports by the government are not incorporated. Therefore, those gaps needs remedial actions to be taken by the center, the government, donors and others who work in partnership.

description: In a variety of different settings cumulative sum (CUSUM) procedures have been applied for the sequential detection of structural breaks in the parameters of stochastic models. Yet their performance depends strongly on the time of change and is best under early-change scenarios. For later changes their finite sample behavior is rather questionable. We therefore propose modified CUSUM procedures for the detection of abrupt changes in the regression parameter of multiple time series regression models, that show a higher stability with respect to the time of change than ordinary CUSUM procedures. The asymptotic distributions of the test statistics and the consistency of the procedures are provided. In a simulation study it is shown that the proposed procedures behave well in finite samples. Finally the procedures are applied to a set of capital asset pricing data related to the Fama-French extension of the capital asset pricing model.

description: A real-space formalism for density-functional perturbation theory (DFPT) is derived and applied for the computation of harmonic vibrational properties in molecules and solids. The practical implementation using numeric atom-centered orbitals as basis functions is demonstrated exemplarily for the all-electron Fritz Haber Institute ab initio molecular simulations (FHI-aims) package. The convergence of the calculations with respect to numerical parameters is carefully investigated and a systematic comparison with finite-difference approaches is performed both for finite (molecules) and extended (periodic) systems. Finally, the scaling tests and scalability tests on massively parallel computer systems demonstrate the computational efficiency.
Kardar-Parisi-Zhang equation and large deviations for random walks in weak random environments

description: We consider the transition probabilities for random walks in $1+1$ dimensional space-time random environments (RWRE). For critically tuned weak disorder we prove a sharp large deviation result: after appropriate rescaling, the transition probabilities for the RWRE evaluated in the large deviation regime, converge to the solution to the stochastic heat equation (SHE) with multiplicative noise (the logarithm of which is the KPZ equation). We apply this to the exactly solvable Beta RWRE and additionally present a formal derivation of the convergence of certain moment formulas for that model to those for the SHE.
