description: Even denominator fractional quantum Hall states in a ZnO quantum well reveal interesting phase transitions in a tilted magnetic field. We have analyzed the planar electron gas in ZnO, confined in a parabolic potential in the third dimension, perpendicular to the plane of the electron gas. Since the Landau level gap is very small in this system we have included the screened Coulomb potential in order to include the effects of all the Landau levels. We observe an incompressible state - compressible state phase transition induced by the tilted field. Additionally, the 5/2 state has been experimentally found to be missing in this system. We however propose that a wider quantum well may help to stabilize the incompressible phase at the 5/2 filling factor.

Determinants of Taxpayers' Voluntary Compliance with Taxation: The Case Study of Dire Dawa City
Creators: name: Tulu, Lemessa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: Improved tax compliance boosts the revenues available for supporting public services without increasing the current tax burden on compliant tax payers. There appears to be a trend in tax compliance policies with initiatives by a number of tax authorities to move towards a more taxpayer focused approach. A number of tax authorities have been moving towards a more sophisticated approach to tax compliance. Traditionally there seems to have been an assumption that tax compliance can be ensured with the help of legal enforcement and penalties. These days this is ceasing to be the case, as the taxpayers are demanding more assistance and fair treatment from the tax authorities. Even there seems to have been a shift in attitudes towards treating the taxpayer less as a passive donor who simply has to be billed for taxes due and more as a customer sometimes requiring particular forms of assistance and support. The voluntary compliance behavior of the taxpayers is determined by various factors and identifying these factors and treating them accordingly should be the central premises of any tax system in order to maintain voluntary compliance at satisfactory levels. This study was meant to identify the determinants of taxpayers' voluntary compliance in Dire Dawa city. Based on this fact the necessary data were collected using standard questionnaire and analyzed. According to the response of the respondents, certain factors were found to be the determinants of taxpayers' voluntary compliance. These are, tax fairness and equity, organizational strength of the tax authority, awareness level of the taxpayers, socio-cultural factors, and provision of social services by the government. Finally, based on the findings possible recommendations were given. These include, maintaining tax fairness and equity, building capacity of the tax authority, conducting extensive awareness creation programs, and providing social services to the general public.

Subjects: subject: Information Theory (cs.IT)

description: In this paper, we study cooperative cognitive radio networks consisting of a primary user and multiple secondary users. Secondary users transmit only when primary user is sensed as silent and may interfere with primary transmission due to imperfect sensing. When primary activity is sensed correctly, secondary users cooperate with primary user by assisting retransmission of failed packets of primary user. We analyze packet throughput of primary and secondary users for three variations of proposed cooperation method. Signal flow graph (SFG) based approach is employed to obtain closed form expressions of packet throughput. The analysis is done for two cases; individual sensing and cooperative sensing. Further, we characterize optimal transmission probability of secondary users that maximizes individual secondary packet throughput keeping all queues in the system stable. Results present a comparison of throughput performance of proposed cooperation methods under different scenarios and show their benefits for both primary as well as secondary user throughput.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Recent financial shocks have generated a lot of debates over the issue of liquidity risk and strategies to mitigate its effects on financial institutions, particularly banks as majors' players in the funding liquidity markets. The purpose of this study is to investigate the impact of liquidity on performance of banks in Ethiopia by using data of eight private commercial banks from year 2009/10 to 2013/14. The study used quantitative research approach and secondary financial data which is analyzed by using multilevel linear regressions models for the three bank performance measures; Return on Asset (ROA), Return on Equity (ROE), and Net Interest Margin (NIM). The random effect multilevel regression model was applied to investigate the impact of liquidity measures; loan to deposit ratio (LDR), loan to asset ratio(LAR), and liquid asset to deposit ratio(LADR) on major bank performance measures i.e., (ROA), (ROE), and (NIM) separately. Eight private banks are randomly selected and considered in the sample out of sixteen private banks representing 50% in number. The study used trend analysis using graphs for each of the variables in the study to observe the trend on them throughout the observation period. The empirical results show that the performance (profitability) measure, NIM, has significant relationship with liquidity measures of LDR, LAR and LADR. The other performance measure, ROE has positive and significant relationship with LADR; but ROA has positive and significant relationship with LADR. Hence, the impact of liquidity on financial performance of private commercial banks in Ethiopia is both positively & negatively related and the significant relationship varies from measure to measure. Finally, there has to be further research apart from bank specific measures considered in this study on the relationship between liquidity and performance of private commercial banks in Ethiopia by incorporating regulatory factors and other bank specific and macroeconomic factors. Further research is recommended on how to achieve the optimal liquidity level in commercial banks. Key words: Liquidity, Liquidity Risk, Performance, Private Banks

description: Drug development productivity has been declining lately due to elevated costs and reduced discovery rates. Therefore, pharmaceutical companies have been seeking alternative ways to determine and evaluate drug candidates. In this work, we proposed a new computational approach to directly predict the regulatory approval of drug candidates, and implemented it as a method called ‘DrugApp.’ To accomplish this task, we employed multiple types of features including molecular and physicochemical properties of drug candidates, together with clinical trial and patent-related features, which are then processed by random forest classifiers to train our disease group-specific approval prediction models. Our evaluations indicated DrugApp has a high and robust prediction performance. Within a use-case study, we showed our method can predict phase IV trial drugs that are later withdrawn from the market due to severe side effects. Finally, we used DrugApp models to forecast the approval of drug candidates that are currently in phases I/II/III of clinical trials. We hope that our study will aid the research community in terms of evaluating and improving the process of drug development.

description: In 1909, Millikan showed that the charge of electrically isolated systems is quantized in units of the elementary electron charge e. Today, the persistence of charge quantization in small, weakly connected conductors allows for circuits where single electrons are manipulated, with applications in e.g. metrology, detectors and thermometry. However, quantum fluctuations progressively reduce the discreteness of charge as the connection strength is increased. Here we report on the full quantum control and characterization of charge quantization. By using semiconductor-based tunable elemental conduction channels to connect a micrometer-scale metallic island, the complete evolution is explored while scanning the entire range of connection strengths, from tunnel barrier to ballistic contact. We observe a robust scaling of charge quantization as the square root of the residual electron reflection probability across a quantum channel when approaching the ballistic critical point, which also applies beyond the regimes yet accessible to theory. At increased temperatures, the thermal fluctuations result in an exponential suppression of charge quantization as well as in a universal square root scaling, for arbitrary connection strengths, in agreement with expectations. Besides direct applications to improve single-electron functionalities and for the metal-semiconductor hybrids emerging in the quest toward topological quantum computing, the knowledge of the quantum laws of electricity will be essential for the quantum engineering of future nanoelectronic devices.

description: Excerpt: Much of the confusion about our own productive capacity stems from viewing capacity in a fixed, physical sense rather than in variable, economic terms. Let us analyze the farm capacity of the United States in dynamic and economic terms. In so doing, four factors should be kept in mind: (1) the time period under consideration, (2) the levels of prices received by farmers, (3) the mix of farm products that is desired, and (4) the amount of public and private investment in future productive capacity.

The Role of ACSI in Addressing Financial Needs of Women Clients Engaged in Micro and Small Enterprise: The case of Bahir Dar Branch.
Creators: name: Mandefro, Gedam
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2010

description: Poor people in general lack access to financial services from formal financial institutions. Poor households pursing micro and small enterprise are excluded from formal institutional credit service. This is because of the high collateral and antiquated lending practice of the formal institutions. Microfinance institutions are considered as a promising source for micro and small business operator specially women throughout the world. Therefore, it is vital to evaluate the role of microfinance programs in addressing financial needs of women engaged in micro and small business sector. The existing operation of the formal financial institutions (Banks) in Ethiopia is inefficient in providing financial services to the poor. Microfinance is considered to meet the gap created by the conventional financial institutions by providing financial service for the productive poor specially women so that they can engage themselves in productive activities, i.e. micro and small business activities. In order to investigate the fundamental premise, this study examined empirical evidence in Amhara Credit and Saving Institution to know its role in addressing financial needs of women clients. Therefore, the objective of this study is to assess the source of startup and working capital, working capital and funds for expansion of the business during operations for women engaged in MSEs sector and to what extent ACSI helps women to address their financial needs. Primary data were collected through interview with manager of the branch office and some selected women clients. Secondary data were gathered from different literature and MFIs reports and publications. The research is both quantitative and qualitative in nature. Descriptive analysis was applied in the study. The role of microfinance is analyzed based mainly on clients' profile, sources of startup capital, sources of working capital, loan methodology and loan size. The finding indicates that ACSI has made significant contribution to address working capital needs of women clients than the other sources of funds of women. However the result also indicates that ACSI has benefited men than women, the loan size is very small to the needs of women, the procedure and regulations are very restrictive to access the loan. Therefore, modifications of loan size and flexibility in operational activities would be appropriate to address financial problem of women in the sector.

description: In der Arbeit sollen nach einem Durchgang durch das Denken Platons, Aristoteles’ und Plotins die Grundzüge der dynamischen Anthropologie des im 4. Jahrhundert lebenden Kirchenvaters Gregor von Nyssa behandelt werden. Mein Ziel ist, Gregors Beitrag zur Vorstellung eines dynamischen Menschen, wie sie vor allem im neuzeitlichen Denken propagiert wurde, vor dem Hintergrund dreier anthropologischer Modelle aus der Antike sichtbar zu machen. Im 1. Teil wird gezeigt, dass der Begriff der Vollkommenheit in der Anthropologie der griechisch-philosophischen Tradition mit dem Erreichen eines Endpunktes der Strebensdynamik zusammenfällt. Im 2. Teil wird nach den Gründen für Gregors These gefragt, dass die Vollkommenheit des Menschen unbegrenzt ist, insofern sie in einem endlosen Aufstieg zu Gott, einem unaufhörlichen Wandel zum Besseren besteht. Es wird dargelegt, dass die Begründung der Grenzenlosigkeit des Aufstiegs bei Gregor nicht nur über den Gedanken der Unendlichkeit Gottes verläuft, sondern auch über jenen der Wandelbarkeit des Menschen, die Gregor der Unwandelbarkeit Gottes gegenüberstellt und durchaus positiv wertet. Die These von der Wandelbarkeit der menschlichen Natur, die mit Gregors Freiheitsbegriff verknüpft ist, soll anschließend vor dem Hintergrund des Denkens Platons, Aristoteles’, Plotins sowie der Freiheitsphilosophie des Origenes beleuchtet werden, um die Besonderheiten von Gregors anthropologischer Konzeption sichtbar zu machen. Hierdurch zeigt sich, dass Gregors Gottesbegriff zwar die Endlosigkeit des Aufstiegs verbürgt. Doch der positive Sinn des endlosen Fortschritts zum Guten, in dem Gregor die Vollkommenheit des Menschen erblickt, wird nur unzureichend erfasst, wenn man nicht mitbedenkt, dass der Mensch dadurch auf die beste Weise seine wandelbare Natur verwirklicht.
Commercial Bank operational risk management: Exploratory study on selected Ethiopian Commercial Banks

description: The purpose of this study is to analyze operational risk management (ORM) of selected Ethiopian commercial banks. As operational risk differs from the other banking risks in terms of its quantification and prediction ability, banks need to measure and manage it carefully as it will have detrimental effect on its entire performance and profitability eventually. The types of data used were both primary and secondary as the research design employed was mixed-mode (Qualitative and quantitative) design. The variables were affirmed reliable fulfilling the minimum 70% requirement of Cronbach"s alpha value. As the study was conducted at institutional level the non probability purposive sampling technique was used to select the banks. Hence, 12 commercial banks have been selected and contacted, where the sample respondents", staffs of risk management section (Risk experts and officers) and internal auditors were used as "key informant" or "Proxy" for the study unit of analysis (Banks). And 96 respondents" for the unit analysis were considered for this study. As the study was constituted a data having an ordinal scale of measurement, the Spearman correlation (Rho) coefficient and principal component analysis (PCA) were used as methods of data analysis. Besides, the descriptive analysis has been used for an interpretation of close ended questions. Analysis of Spearman Correlation (Rho) coefficient findings has resulted into existence of significant positive correlation coefficient between the variables tough the degree of strength differs. Principal component analysis as factor analysis method has resulted into an extraction of 6 factors as useful factors out of the initial 20 factors considered based on an Eigen value, λ>1.0 which all together accounts for about 64% of variance. The descriptive analysis of the board approval of policies and procedures of banks operational risk has shown the presence of board approval on the different issues of banks operational risk, based on majority of the responses though it wouldn"t guarantee the presence of effective ORM. It is highly recommended to have committed management and strong internal control mechanisms for an effective ORM.

description: Scintillation properties of the new Tl2LaCl5: xCe3+ where x = 0, 0.5, 1 and 10 mole % (TLC: Ce3+) single crystals are presented. Two zones vertical Bridgman technique is used for the growth of this scintillation material. High Z-number (79) of this material offer excellent detection efficiency for X- and γ-rays. Grown samples are characterized under X- and γ-rays excitation in order to find the emission wavelength, energy resolution, light yield, and decay time. Emission spectra exhibit Ce3+ emission bands between 350 - 550 nm and peaking at 389 nm. The obtained energy resolution and light yield increases with high Ce-concentration. Energy resolution and light yield of 10%Ce-doped sample are found to be 6.9% (FWHM) and 51,000+-5000 ph/MeV, respectively at room temperature. For the grown samples, two exponential decay time constants are found. The measured decay time constants showed variation in their values with respect to Ce-concentrations in the host crystal. Fast decay time constant of 31 ns with 87% light emission is found for 10%Ce sample. Scintillation results suggested that TLC will be one of the promising next generation scintillator for the medical imaging techniques such as Positron Emission Tomography (PET).

description: Through an extensive set of realistic synthetic observations (produced in Paper I), we assess in this part of the paper series (Paper III) how the choice of observational techniques affects the measurement of star-formation rates (SFRs) in star-forming regions. We test the accuracy of commonly used techniques and construct new methods to extract the SFR, so that these findings can be applied to measure the SFR in real regions throughout the Milky Way. We investigate diffuse infrared SFR tracers such as those using 24 μm, 70 μm and total infrared emission, which have been previously calibrated for global galaxy scales. We set up a toy model of a galaxy and show that the infrared emission is consistent with the intrinsic SFR using extra-galactic calibrated laws (although the consistency does not prove their reliability). For local scales, we show that these techniques produce completely unreliable results for single star-forming regions, which are governed by different characteristic timescales. We show how calibration of these techniques can be improved for single star-forming regions by adjusting the characteristic timescale and the scaling factor and give suggestions of new calibrations of the diffuse star-formation tracers. We show that star-forming regions that are dominated by high-mass stellar feedback experience a rapid drop in infrared emission once high-mass stellar feedback is turned on, which implies different characteristic timescales. Moreover, we explore the measured SFRs calculated directly from the observed young stellar population. We find that the measured point sources follow the evolutionary pace of star formation more directly than diffuse star-formation tracers.

description: The Porter-Thomas (PT) distribution of resonance widths is one of the oldest and simplest applications of statistical ideas in nuclear physics. Previous experimental data confirmed it quite well but recent and more careful investigations show clear deviations from this distribution. To explain these discrepancies the authors of [PRL \textbf{115}, 052501 (2015)] argued that to get a realistic model of nuclear resonances is not enough to consider one of the standard random matrix ensembles which leads immediately to the PT distribution but it is necessary to add a rank-one interaction which couples resonances to decay channels. The purpose of the paper is to solve this model analytically and to find explicitly the modifications of the PT distribution due to such interaction. Resulting formulae are simple, in a good agreement with numerics, and could explain experimental results.

description: We present the results of numerical study of the phase dynamics of the DC-SQUID with topologically trivial and nontrivial barriers. In our calculations we take into account two components of supperconducting current, Cooper pairs ($2π$-periodic) and Majorana fermions ($4π$-periodic) currents. Magnetic field dependence of return current is presented. The qualitative behavior of this dependence is explained. We show that in case of two component superconducting current the periodicity of magnetic field dependence of return current displaced by Cooper pairs and Majorana fermion ratio over the magnetic field. This effect makes possible the experimental determination of ratio of Cooper pairs and Majorana fermions currents.

description: The present study investigates Vibrio outbreak in the hatchery system designed for larval rearing of shovel-nosed lobster Thenus unimaculatus in India. High larval mortalities during the episode led to an almost complete loss of the larval stock during the first 10 days. Microscopic examination revealed heavy fouling of the phyllosoma appendages. Histopathological analysis showed the presence of bacteria in larval tissues. Investigation by scanning electron microscopy revealed the formation of bacterial plaques on appendages and adhesion of bacteria on fine setae in heavily infected larvae. Bacteria isolated from larvae and identified by 16S rRNA sequencing and phylogenetic analysis indicated that the strains were closely related to luminescent Vibrio campbellii and Vibrio harveyi. The virulence potential of Vibrio strains isolated from larvae was evaluated through an experimental infection. The study helps to understand microbial infection and its impact on phyllosoma survival and may allow a more effective health management regime to improve larval survival in the hatchery phase.
Skilled Manpower Turnover and Its Management The Case of Ethiopian Roads Authority
Creators: name: Aberra, Solomon
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: Employee turnover is an important and pervasive feature of the labour market. Employee turnover affects both workers and the firms. Workers experience disruption, the need to learn new job-specific skills and find different career prospects. Firms suffer the loss of job-specific skills, disruption in production and incur the costs of hiring and training new workers. Turnover is a serious and costly problem but it is rarely seen as such by the people who could take action to prevent it. Often they fail to take action partly because departing employees couch their reasons of leaving in cryptic and euphemistic language. They do so because they distrust the company –often one of their reasons for leaving. Many upper managers believe that departing employees are going to a better place, and not leaving an undesirable one-sometimes because that is what they want to believe. A high level of Labour Turnover could be caused by many factors such as inadequate wage levels leading employees to move to competitors; poor morale and low level of motivation within the workforce; recruiting and seeking the wrong employees in the first place; a buoyant local labour market offering more attractive opportunities to employees and miss-match between employee's personal values, career, goals and plans with the larger corporate culture. High labour turnover has become a problem for government institutions. Well experienced and qualified professionals leave position they held in government offices. Ethiopia Roads Authority is one of the victims of this high labour turnover. Currently the Ethiopian Roads Authority is facing a frequent turnover of staff, and as such the high turnover is costing the authority in terms of productivity, money and time.

For a Reynolds number Re=1000, we study the effect of increasing Hartmann number Ha. The resulting flow structures are inspected by ultrasound Doppler velocimetry. With a weak applied magnetic field, we observe an equatorially anti-symmetric jet instability with azimuthal wave number m=3. As the magnetic field strength increases, this instability vanishes. When the field is increased further, an equatorially symmetric return flow instability arises. Our observations are shown to be in good agreement with linear stability analysis and non-linear flow simulations.

description: Context: Companies that operate in the software-intensive business are confronted with high market dynamics, rapidly evolving technologies as well as fast-changing customer behavior. Traditional product roadmapping practices, such as fixed-time-based charts including detailed planned features, products, or services, typically fail in such environments Until now the underlying reasons for the failure of product roadmaps in a dynamic and uncertain market environment are not been widely analyzed and understood. Objective: This paper aims to identify current challenges and pitfalls practitioners face when developing and handling product roadmaps in a dynamic and uncertain market environment. Method: In order to reach our objective we conducted a grey literature review (GLR). Results: Overall we identified 40 relevant papers, from which we could extract 11 challenges of the application of product roadmapping in a dynamic and uncertain market environment. The analysis of the articles showed that the major challenges for practitioners originate from overcoming a feature-driven mindset, not including a lot of details in the product roadmap as well as ensuring that the content of the roadmap is not determined on the opinions of management or experts. The results of our study can be used to derive requirements for the development of approaches for a successful product roadmapping in a dynamic and uncertain market environment.

In contrast to existing techniques like coronagraphy, we apply well-established techniques from integrated optics to exclusively extinct a very narrow angular direction coming from the sky. This extinction is achieved in the pupil plane and does not suffer from diffraction pattern residuals. We give a comprehensive presentation of the underlying theory as well as first laboratory results.

Year: 2015

description: Examining employees' reaction to organizational change using employees' perception about organizational change variables was the aim of this study. The independent variables are perceived organizational support, perceived procedural justice, perceived fear of consequences of a change, perceived self-confidence for learning and development, perceived trust in management and perceived Need for change and the dependent variable is reaction to change. The study used quantitative data by using survey method and structured survey questionnaires were distributed to 373 (three hundred seventy three) Employees of Ethiopian Revenue and Custom Authority in seven branches were selected by using stratified sampling technique. Beside this simple random sampling technique used to select the employees as respondent. SPSS version 20 also employed to analysis the data. Pearson's correlation matrix was used to show the relationship' between the dependent and the independent variables. The researcher also used multiple regression tools to examine the effects of independent variables on dependent variable. The multiple regression result indicates that, perceived organizational support, perceived procedural justice, perceived self-confidence to learning and development, perceived trust in management and perceived need for change have negative and significant effect on resistance to change while it is positive and significant effect on support to change. Unlike this perceived fear of consequence of change is positive and significant effect on resistance to change whereas it is insignificant to support to change. Key words: organizational change, attitude, perception, resistance to change, support to change, reaction to change

description: Zero-attracting least-mean-square (ZA-LMS) algorithm has been widely used for online sparse system identification. It combines the LMS framework and $\ell_1$-norm regularization to promote sparsity, and relies on subgradient iterations. Despite the significant interest in ZA-LMS, few works analyzed its transient behavior. The main difficulty lies in the nonlinearity of the update rule. In this work, a detailed analysis in the mean and mean-square sense is carried out in order to examine the behavior of the algorithm. Simulation results illustrate the accuracy of the model and highlight its performance through comparisons with an existing model.

title: Putinism as a political regime
Creators: name: Ovcharenko, Mariia
Year: 2023

description: Putinismus ist ein Begriff, der verwendet wird, um das politische und sozioökonomische System zu beschreiben, das unter der Führung von Wladimir Putin in Russland entstanden ist. Diese Zusammenfassung bietet einen Überblick und eine Analyse der wichtigsten Merkmale und Dynamiken des Putinismus und wirft Licht auf dessen Ursprünge, Eigenschaften und Auswirkungen. Die Ursprünge des Putinismus lassen sich auf den Zusammenbruch der Sowjetunion und die anschließenden politischen und wirtschaftlichen Turbulenzen in Russland zurückführen.
description: Putinism is a term used to describe the political and socioeconomic system that has emerged under the leadership of Vladimir Putin in Russia. This abstract provides an overview and analysis of key features and dynamics of Putinism, shedding light on its origins, characteristics, and implications. The origins of Putinism can be traced back to the collapse of the Soviet Union and the subsequent political and economic turmoil in Russia. As a response to these challenges, Putin rose to power in the early 2000s, presenting himself as a strong leader capable of restoring stability and asserting Russia's influence on the global stage.

description: Resilient and profitable banks can contribute immensely to the development of financial sector in particular and the country's development in general. The study employed autoregressive distributed lag (ARDL) to examine the relationship and behavior of liquidity and profitability of the commercial banking industry in Ethiopia. Quarterly consolidated financial statements of fifteen commercial banks that covers the period 2003Q2 – 2014Q3 is used for this study. Augmented Dickey Fuller (ADF) is used to test for unit root. In attempt to draw valid conclusion, diagnostic tests are carried out for serial correlation, heteroscedasticity, and normality. In order to check the stability of long-run coefficients that form the error-correction term in combination of short-run dynamics, cumulative sum of recursive residuals test (CUSUM) and the cumulative sum of squares of recursive residuals test(CUSUMQ) is applied to the residuals of the models. The estimation result of the error correction model shows that the speed of adjustment of liquidity and profitability to long run equilibrium is faster in the commercial banking industry of Ethiopia. The results of ARDL estimation shows that loan growth, bank size, credit risk, saving deposit growth, demand deposit growth, and fixed deposit growth are key determinants of liquidity both in the short and long term. While non-interest income and operating expenses management are the key determinants of profitability both in the short and long term. The result of pairwise Granger causality test shows that neither unidirectional nor bidirectional pattern of causality exists between liquidity and profitability. Key words: ARDL, Liquidity, Profitability, Granger causality, Error correction model, Commercial banking industry

description: Condensed matter systems can host quasiparticle excitations that are analogues to elementary particles such as Majorana, Weyl, and Dirac fermions. Recent advances in band theory have expanded the classification of fermions in crystals, and revealed crystal symmetry-protected electron excitations that have no high-energy counterparts. Here, using angle-resolved photoemission spectroscopy, we demonstrate the existence of a triply degenerate point in the electronic structure of MoP crystal, where the quasiparticle excitations are beyond the Majorana-Weyl-Dirac classification. Furthermore, we observe pairs of Weyl points in the bulk electronic structure coexisting with the 'new fermions', thus introducing a platform for studying the interplay between different types of fermions.

Year: 2019

description: The study examined Factors that affecting E-banking satisfaction in commercial bank of Ethiopia. A total of 340 questionnaires for customers and 67 for employee at e-payment department were properly filled and returned and two interviews questions are prepared and asked for two managers and one team leaders of e-payment were conducted and also random sampling were employed. Both primary and secondary data was collected for the purpose of this study. Primary data were collected using likert scale based questionnaires. After the collection of raw data, classification and tabulation was done by the researcher to make it ready for the analysis. And the data was analyzed using descriptive statistics. (Correlation analysis& multiple regression models) and secondary data also used like bank manual, annual reports and different books related to Ebanking were used. The empirical findings show that service quality dimensions (reliability, assurance, responsiveness, empathy and tangibility) have significant relationship with customer satisfaction e-banking. Except Tangibility service quality dimensions (reliability, assurance, responsiveness & empathy) have positive and significant impact on customer satisfaction in e-banking of commercial bank of Ethiopia. The basic challenging problems faced by commercial banks of Ethiopia in relation to E-banking are insecurity, erratic power supplies, as well as difficulty in transacting business electronically were the main challenges associated with electronic Banking. Also Infrastructure (telecommunication and power), lack of centrally followed country initiative in similar manner with other African countries, strong cash habit, technology phobia, lack of trust on it and lack of Merchants' willingness in relation with POS service are external challenge. Poor employee awareness in terms of service delivery, maintenance support and lack of a comprehensive performance measurement system are internal challenges Finally in the last part of the study recommendation of the study is presented
Ultra High Energy Cosmic Rays & Super-heavy Dark Matter

description: We reanalyse the prospects for upcoming Ultra-High Energy Cosmic Ray experiments in connection with the phenomenology of Super-heavy Dark Matter. We identify a set of observables well suited to reveal a possible anisotropy in the High Energy Cosmic Ray flux induced by the decays of these particles, and quantify their performance via Monte Carlo simulations that mimic the outcome of near-future and next-generation experiments. The spherical and circular dipoles are able to tell isotropic and anisotropic fluxes apart at a confidence level as large as $4σ$ or $5σ$, depending on the Dark Matter profile. The forward-to-backward flux ratio yields a comparable result for relatively large opening angles of about 40~deg, but it is less performing once a very large number of events is considered. We also find that an actual experiment employing these observables and collecting 300~events at 60~EeV would have a $50\%$ chance of excluding isotropy against Super-heavy Dark Matter at a significance of at least $3σ$
