description: Cosmic strings, if they exist, source nonlinear and non-Gaussian perturbations all the way back to the time of equal matter and radiation (and earlier). Here, we compute the mass function of halos seeded by a scaling distribution of cosmic string loops, and we compare the results with the predictions of the standard Gaussian $Λ$CDM model. Assuming a simple linear relation between stellar mass and halo mass, we also compute the stellar mass function. The contribution of cosmic strings dominates at sufficiently high redshifts $z > z_c$ where $z_c$ depends on the mass of the halo and on the mass per unit length $μ$ of the strings and is of the order $z_c \sim 12$ for $Gμ= 10^{-8}$. We find that strings with this value of $Gμ$ can explain the preliminary JWST data on the high redshift stellar mass density. Based on an extreme value statistic, we find that the mass of the heaviest expected string-seeded galaxy for the current JWST sky coverage is compatible with the heaviest detected galaxy. Given the uncertainties in the interpretation of the JWST data, we discuss predictions for higher redshift observations.

description: The Effect of Branding on Customers Preference of Hotel Brands: The Case of Four Star Hotels in Hawassa, Ethiopia Solomon G/selassie Addis Ababa University, 2018 Branding is an influential marketing tool that when used efficiently and effectively could provide value for the stakeholders, mainly company and customers, then evaluating the degree of the importance of branding, matters must be assessed from both sides. As the market becomes more competitive with products and services, which are substitutes, the study of Brand Trust will become more crucial. Thus, this study was intended to study the causal effect relationship between branding and consumers' preferences on hotel brands in a fast-growing city located on the shores of Lake Hawassa, south of Addis Ababa. Out of 384-target population, 320 respondents returned completed and properly filled questionnaires, which meant 83.33 percent coverage of total respondents from the customers of these hotels. Using quantitative research approach, and descriptive and explanatory research design, it was found that brand image consumer preferences (4.21) were rated as at much and brand experience (4.11), brand awareness (4.01), brand attitude (4.16), brand trust (3.99) and the mean value for all variables ranges from 3.99 to 4.29 and it indicates that most respondents' response or preferred the category of agree and there is correlation between brand image (r=0.628), brand awareness (r=0.43), brand experience (r=0.522), brand attitude (r=0.545) and brand trust (r=0.693) and consumers preferences with statistically significant (Sig. (2-tailed) = 0.000). Moreover, from the result, it can be concluded that with 59.9% of the variance (R-Square) in brand image, brand awareness, brand experience, brand attitude and brand trust have significant effect on consumers preferences and the model adopted appropriately measure the construct. It is sure that marketers need to understand consumer behavior to compete with rivals. Consumers may be irrational people who make decisions not on based rational reasons

description: We theoretically investigate a novel supersolid structure taking the form of stacked, disk-shaped superfluid droplets connected via a dilute superfluid, in an antidipolar condensate. A phase diagram is determined for varying the particle number and scattering length, identifying the regions of a regular dipolar superfluid, supersolid stacks, and isolated stacked disk-shaped droplets in an experimentally realizable trapping potential. The collective Bogoliubov excitation spectrum across the superfluid-supersolid phase transition is studied, and the transition point is found to be associated with the breaking of the degeneracy of the two lowest-lying modes. The dynamical generation of the supersolid stacks is also investigated by ramping down the scattering length across the phase transition. Moreover, we have studied the impact of vortex-line penetration on the phase transition. We have found that the presence of a vortex line causes the supersolid region to move towards weaker contact interactions. Our detailed numerical simulations highlight that an antidipolar condensate can create such supersolid stacks within an experimentally reachable parameter regime.

description: Instantaneous quantum computing is a sub-universal quantum complexity class, whose circuits have proven to be hard to simulate classically in the Discrete-Variable (DV) realm. We extend this proof to the Continuous-Variable (CV) domain by using squeezed states and homodyne detection, and by exploring the properties of post-selected circuits. In order to treat post-selection in CVs we consider finitely-resolved homodyne detectors, corresponding to a realistic scheme based on discrete probability distributions of the measurement outcomes. The unavoidable errors stemming from the use of finitely squeezed states are suppressed through a qubit-into-oscillator GKP encoding of quantum information, which was previously shown to enable fault-tolerant CV quantum computation. Finally, we show that, in order to render post-selected computational classes in CVs meaningful, a logarithmic scaling of the squeezing parameter with the circuit size is necessary, translating into a polynomial scaling of the input energy.

Search for anomalous Wtb couplings and flavour-changing neutral currents in t-channel single top quark production in pp collisions at sqrt(s) = 7 and 8 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Single top quark events produced in the t channel are used to set limits on anomalous Wtb couplings and to search for top quark flavour-changing neutral current (FCNC) interactions. The data taken with the CMS detector at the LHC in proton-proton collisions at sqrt(s) = 7 and 8 TeV correspond to integrated luminosities of 5.0 and 19.7 inverse femtobarns, respectively. The analysis is performed using events with one muon and two or three jets. A Bayesian neural network technique is used to discriminate between the signal and backgrounds, which are observed to be consistent with the standard model prediction. The 95% confidence level (CL) exclusion limits on anomalous right-handed vector, and left- and right-handed tensor Wtb couplings are measured to be |f[V]^R| < 0.16, |f[T]^L| < 0.057, and -0.049 < f[T]^R < 0.048, respectively. For the FCNC couplings kappa[tug] and kappa[tcg], the 95% CL upper limits on coupling strengths are |kappa[tug]|/Lambda < 4.1E-3 TeV-1 and |kappa[tcg]|/Lambda < 1.8E-2 TeV-1, where Lambda is the scale for new physics, and correspond to upper limits on the branching fractions of 2.0E-5 and 4.1E-4 for the decays t to ug and t to cg, respectively.

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

description: The purpose of this study was to assess the reward system on clerical employees' performance: the case of CBE selected North Addis Ababa District city branches. To address the research question, the researcher has conducted interviews with the three branch managers of the selected branches. In addition to this, the analysis was done by the help of SPSS version 20 and presented using descriptive statistics. Tables are used to provide information on the variables. Interpretation is made on the frequency and percentage of the data. The results are investigated in terms of descriptive statistics followed by inferential statistics on the variables. A total of 272 questionnaires were distributed to the employees in the selected branches and a total of 250 employees completed the questionnaire properly. The study's result has implied that employees of the bank were not motivated by the bank's reward system. Even though the bank implemented both financial and nonfinancial rewards, currently the financial reward that implemented is not attractive when comparing with competitors and current market. Employees like to be consulted what they need most when they perform better. Therefore the bank should modify the existing reward system especially financial rewards, make available exceptional rewards to retain skilled and high performing employee and also the bank should devise a mechanism to attach rewards with individual performance. Finally, the researcher's lack of prior experience in conducting systematized research and absence of prior works on the subject matter in Ethiopian context would have some impact on the results of the study that will call up for other researchers to prove the reliability of this study Key words: Reward system, reward types, Employee Performance

description: We consider the general thermal asymptotically flat Kerr-Newman black holes in 4d Einstein-Maxwell theory. Even though their thermodynamics has been understood for decades, the Gibbs free energy and on-shell action are only known implicitly as functions of the standard chemical potentials. Using the so-called left and right moving (or holomorphic and anti-holomorphic) variables related to the chemical potentials on both the outer and the inner horizons, we are able to present explicit and very simple expressions for all quantities. We discuss various limits in the parameter space, remarkably finding a smooth BPS limit allowing direct access to the extremal surface. In the BPS limit the anti-holomorphic part of the on-shell action vanishes identically, leading automatically to the holomorphic expression expected microscopically. This gives us confidence that the newly defined thermal partition function in terms of these variables is the natural candidate for a full microscopic description.

Interaction effects on the classification of crystalline topological insulators and superconductors

Year: 2016
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We classify interacting topological insulators and superconductors with order-two crystal symmetries (reflection and twofold rotation), focusing on the case where interactions reduce the noninteracting classification. We find that the free-fermion $\mathbb{Z}_2$ classifications are stable against quartic contact interactions, whereas the $\mathbb{Z}$ classifications reduce to $\mathbb{Z}_N$, where $N$ depends on the symmetry class and the dimension $d$. These results are derived using a quantum nonlinear $σ$ model (QNLSM) that describes the effects of the quartic interactions on the boundary modes of the crystalline topological phases. We use Clifford algebra extensions to derive the target spaces of these QNLSMs in a unified way. The reduction pattern of the free-fermion classification then follows from the presence or absence of topological terms in the QNLSMs, which is determined by the homotopy group of the target spaces. We show that this derivation can be performed using either a complex fermion or a real Majorana representation of the crystalline topological phases and demonstrate that these two representations give consistent results. To illustrate the breakdown of the noninteracting classification we present examples of crystalline topological insulators and superconductors in dimensions one, two, and three, whose surfaces modes are unstable against interactions. For the three-dimensional example, we show that the reduction pattern obtained by the QNLSM method agrees with the one inferred from the stability analysis of the boundary modes using bosonization.

Year: 2018

description: Marketing strategies constitute one of the key functional strategies that Small and Medium Enterprises (SMEs) adopt to enhance performance. This study is aimed to examine the effect of marketing strategy on SMEs performance in Addis Ababa City. By taking the research objectives and questions into considerations, only quantitative research approach and both descriptive and explanatory research design were used. The study was delimited to proportionate stratified and purposive sampling techniques. Quantitative data was collected using a structured questionnaire which has been developed and distributed to a sample of 365 owners and/or managers of SMEs in the three sub-cities (Lideta, Yeka, and Kirkos). With a response rate of 94%, 344 questionnaires have been returned and were valid for data analysis. The quantitative data were analyzed by using descriptive and inferential analysis. The findings of descriptive statistics have shown that the mean score of marketing strategy variables i.e. STP, product, price, promotion, place, customer orientation, and relationship marketing inclined to agreement level. All independent variables have the significant correlation with the dependent variable "performance". In this case, relatively relationship marketing had a higher strong relationship with performance. Likewise, the empirical findings of the multiple regression indicated that, only six of the predictor variables STP, Product, Promotion, Place, Customer Orientation, and Relationship Marketing have a positive and significant effect on the Performance of SMEs but, price is not. The results also revealed that these independent variables were significant joint predictors of performance. The independent variables jointly explained 61.5% of the variance in performance. Finally, recommendations were made for SMEs based on the findings of the study.

description: The energy dependence of Tsallis statistics parameters is presented for charged pions produced at beam energies ranging between 6.3 GeV and 7 TeV. It is found that deviations from Boltzmann statistics are monotonically growing with beam energy. This may be attributed to the dominance of low $x$ at higher energies leading to the power-like NLO QCD spectra for which Tsallis statistics may serve as effective theory. At the same time, for larger $x$ at lower beam energies the Gaussian falloff of transverse-momentum-dependent distributions is crucial and correspondent effective description is provided by the Boltzmann distribution.

description: Welfare-state measures often tend to persist even when they seem to have become suboptimal due to changes in the economic environment. This paper proposes an information-based explanation for this welfare-state persistence. I present a structural model where rationally inattentive voters decide upon implementations and removals of social insurance. In this model, welfare- state persistence arises from disincentive effects of social insurance on attentiveness. The welfare state crowds out private financial precautions and with it agents' attentiveness to changes in economic fundamentals. When welfare-state arrangements are pronounced, agents realize changes in economic fundamentals later and reforms have considerable delays.

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The {\it Kepler} mission has detected thousands of planetary systems with 1-7 transiting planets packed within 0.7~au from their host stars. There is an apparent excess of single-transit planet systems that cannot be explained by transit geometries alone, when a single planetary mutual inclination dispersion is assumed. This suggests that the observed compact planetary systems have at least two different architectures. We present a scenario where the "Kepler dichotomy" may be explained by the action of an external giant planet or stellar companion misaligned with the inner multi-planet system. The external companion excites mutual inclinations of the inner planets, causing such systems to appear as "Kepler singles" in transit surveys. We derive approximate analytic expressions (in various limiting regimes), calibrated with numerical calculations, for the mutual inclination excitations for various planetary systems and perturber properties (mass $m_p$, semi-major axis $a_p$ and inclination $θ_p$). In general, the excited mutual inclination increases with $m_p/a_p^3$ and $θ_p$, although secular resonances may lead to large mutual inclinations even for small $θ_p$. We discuss the implications of our results for understanding the dynamical history of transiting planet systems with known external perturbers.

The Impact of public Sector Spending on the Economic Growth A particular Focus on Road and Electric Power Sector (The Case of Ethiopia)
Creators: name: Kebede, Bayew
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The government of Ethiopia for the past ten years is exercising an expansionary fiscal policy with the aim of providing major public infrastructure services in the country. With regard to this, the government have increased the level of total public expenditure by more than hundred percent in GTP periods. Taking in to account the shortage of capital to finance public expenditures in Ethiopia, both the short run and long run effects of this government spending have to be measured to determine whether the expenditure is creating the intended economic growth. Short run economic outburst can misled governments that the existing public expenditure will have a positive outcome also in the long run while it may not. On the other hand, the increase in public expenditure can result in resource absorption from the productive private sector, which most scholars argue to be more efficient, to public sector. The objective of this paper is to analyze the impact of government spending on economic growth in Ethiopia. In doing so, considering the complexity of the link between government spending and economic growth, both descriptive explanations and econometric analysis were applied in the study. In addition, key informant interview was made in order to triangulate the empirical results obtained. The descriptive analysis found that the trend of public spending in Ethiopia and the deficit level is growing adjacently in recent years. However, the level of accumulated public debt borrowed to finance the deficit is at low risk according to IMF standard of high risk dept level. The empirical analysis found that public spending on social sectors has positive long run effect on the growth of real percapita income while spending on general services is suppressing its growth. From the selected infrastructure sector components, while public expenditure on electric power sector has significant positive effect, road sector development has insignificant effect on the growth of real percapita income growth

description: The fractional Josephson effect has been observed in many instances as a signature of a topological superconducting state containing zero-energy Majorana modes. We present a nontopological scenario which can produce a fractional Josephson effect generically in semiconductor-based Josephson junctions, namely, a resonant impurity bound state weakly coupled to a highly transparent channel. We show that the fractional ac Josephson effect can be generated by the Landau-Zener processes which flip the electron occupancy of the impurity bound state. The Josephson effect signature for Majorana modes become distinct from this nontopological scenario only at low frequency. We prove that a variant of the fractional ac Josephson effect, namely, the low-frequency doubled Shapiro steps, can provide a more reliable signature of the topological superconducting state.

description: Lead white is the most ancient and common white pigment used in mural paintings. However, it tends to blacken with time due to its oxidation to plattnerite (\b{eta}-PbO2). Chemical treatments were used but they can put the pictorial layers supports at risks. Hereby we address the possibility of thermally reconverting black plattnerite to white lead carbonates via a massicot (\b{eta}-PbO) intermediate, with a view to developing a restoration procedure using continuous wave laser heating. We first investigated the conditions (temperature, time, and environment) in which pure powders react, before studying mural painting samples. Experiments were made in ovens and TGA and XRD and SEM characterization were achieved. Litharge (α-PbO) and massicot were obtained from plattnerite respectively between 564 and 567 °C and at 650 °C. Lead carbonates (cerussite, hydrocerussite and plumbonacrite) formed from massicot in wet CO2 below 100 °C in a few hours. Lastly, when heating plattnerite based mural painting samples, lead species reacted with binders and mortar, yielding massicot, plumbonacrite but also lead silicate and calcium lead oxides. This demonstrates the viability of thermal reconversion of darkened lead in mural, while raising concerns about the formation of several lead species by reaction with mural painting constituents.

description: It is shown that certain sets of normalised unity-resolving (e.g. coherent) states in Hilbert space serve to generate upper bounds on the partition function of a given Hamiltonian in that space. These bounds may be viewed as generalisations of bounds derived previously by Golden, Thompson, Hepp and Lieb (see Phys. Rev. A, vol.8, p.2517, 1973). The new bounds are compared to the original Golden-Thompson bound by proving several theorems and by computing explicit examples.

description: Erkennung der Toneinsätze in Musikaufnahmen ist der erste und sehr wichtige Schritt bei der Musiktranskription. Es existieren bereits sehr viele Algorithmen, die diesem Ziel dienen. Bei den meisten davon werden die Algorithmusparameter mittels genetischer Verfahren so optimiert, dass diese Algorithmen für alle Musikinstrumente durchschnittlich die besten Erkennungsraten liefert. Dabei sind die Klangeigenschaften von Instrumenten verschiedener Instrumentenarten sehr unterschiedlich, so dass es sinnvoll ist, optimale Parametereinstellungen in Abhängigkeit von Instrumentenklassen zu bestimmen. Bei Musikstücken, die von mehreren Instrumenten gespielt werden, ist dieses Problem allerdings komplizierter. Ziel dieses Berichtes ist, einen einfachen Algorithmus zur Einsatzzeiterkennung auf Tonabfolgen verschiedener Musikinstrumente zu testen, um zunächst grobe Zusammenhänge zwischen Einstellungen von Algorithmusparametern und Instrumentenart zu bestimmen. Wegen großer Unterschiede zwischen echten und synthetischen Musiktönen bezüglich ihrer Klangeigenschaften wird großer Wert auf die Erzeugung von Tonabfolgen mittels echter Tonaufnahmen gelegt. Dazu wird in dieser Arbeit ein Verfahren vorgestellt.

description: Reference potential approach (RPA) is successful in obtaining inverse potentials for weakly bound diatomic molecules using Morse function. In this work, our goal is to construct inverse potentials for all available l-channels of np-scattering using RPA. The Riccati-type phase equations for various l-channels are solved using 5th order Runge-Kutta method to obtain scattering phase shifts (SPS) in tandem with an optimization procedure to minimize mean squared error (MSE). Interaction potentials for a total of 18 states have been constructed using only three parameter Morse interaction model. The obtained MSE is < 1% for 1S0 , 3P1 and 3D1 channels and < 2% for 1P1 channel and < 0.1% for rest of the 14 channels. The obtained total scattering cross-sections at various lab energies are found to be matching well with experimental ones. This phase wave analysis study of all channels of np-scattering using RPA has been undertaken using Morse function as zeroth reference, by us, is for the first time.

description: The blind structured illumination microscopy (SIM) strategy proposed in (Mudry et al., 1992) is fully re-founded in this paper, unveiling the central role of the sparsity of the illumination patterns in the mechanism that drives super-resolution in the method. A numerical analysis shows that the resolving power of the method can be further enhanced with optimized one-photon or two-photon speckle illuminations. A much improved numerical implementation is provided for the reconstruction problem under the image positivity constraint. This algorithm rests on a new preconditioned proximal iteration faster than existing solutions, paving the way to 3D and real-time 2D reconstruction

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: This study examines the various bank specific and macroeconomic variables that affect the banking system stability in Ethiopia during the study period ranging from 2000 to 2013. Arellano-Bond estimation technique had been employed to estimate the various determinants. From the Empirical result of this paper it was concluded that previous year banking system stability, economic growth and lending growth to the private sector were amongst determinants that affect the banking system stability positively; whereas total bank's asset, inflation and real interest rate were found to negatively affect the banking system stability; whilst government budget deficit, exchange rate volatility and treasury bills were found not having any impact on the banking system stability in Ethiopia. The policy implications of these results is so vital to the banking industry in Ethiopia, incase that most of the variables can be maintained and controlled by the National Bank of Ethiopia. The researcher thus finally puts the policy implications based on these results. To maintain the banking system stability in Ethiopia the researcher recommends to uphold: the economic growth of the country, previous year's banking system stability, bank lending growth and increasing the management's aptitude especially to lessen the diseconomies of scale in the banking industry; on the contrary the researcher recommends to dwindle the inflation rate and interest rate.

description: We demonstrate matterwave interference in a warm vapor of rubidium atoms. Established approaches to light pulse atom interferometry rely on laser cooling to concentrate a large ensemble of atoms into a velocity class resonant with the atom optical light pulse. In our experiment, we show that clear interference signals may be obtained without laser cooling. This effect relies on the Doppler selectivity of the atom interferometer resonance. This interferometer may be configured to measure accelerations, and we demonstrate that multiple interferometers may be operated simultaneously by addressing multiple velocity classes.

description: Image denoising is an important pre-processing step in medical image analysis. Different algorithms have been proposed in past three decades with varying denoising performances. More recently, having outperformed all conventional methods, deep learning based models have shown a great promise. These methods are however limited for requirement of large training sample size and high computational costs. In this paper we show that using small sample size, denoising autoencoders constructed using convolutional layers can be used for efficient denoising of medical images. Heterogeneous images can be combined to boost sample size for increased denoising performance. Simplest of networks can reconstruct images with corruption levels so high that noise and signal are not differentiable to human eye.

description: In marketing, efficiency is one of cost benefits analysis measurement tools that are used to determine by some factors. Among these factors, price discovery, quality grading, risk management, clearing and settlement, market data dissemination, and transaction cost has been used for this study. Today, the attitude of marketing philosophies are changed thus the researcher have tried to find out really these factors of market efficiency affect the market interaction. Efficiency in marketing is the most used measure of market performance. Improved marketing efficiency is a common goal of farmers, marketing organizations, consumers, and society. The research had the objective of identifying and explaining the factors of Market Efficiency of ECX. In order to address its objectives, the research has been generally set conceptual framework. Triangulation of data in the realm of qualitative and quantitative research methods employing interview and questionnaire data analysis have been employed respectively. Four key informants representing other department heads have been purposively selected. In addition, random sampling has been used to analyze data collected through questionnaires of ECX members and 185 market actors have been involved in the study. The finding of the study shows that there is a direct and positive relationship between most of factors of market efficiency. All the factors of market efficiency measures have positive effect on market efficiency, among which clearing and settlement has the highest effect with coefficient followed by market data dissemination, risk management, price discovery, and quality grading respectively. But, transaction cost has a negative effect on the market efficiency. ECX recommended developing a market efficiency strategy and policy in concerning about the strong and lesser performance of each factors of market efficiency and also including others variable which is not in this study. ECX advised that to give them a chance to be active participants in the trading system in the presents of challenging was happened. Especially, Exporters may have determined some factors of market efficiency due to experience sharing with abroad business interaction. In the case of information and transportation infrastructures ECX recommended that in revised and developed system to have a good culture of working together with other governmental organization to enhance the market efficiency and make synergy effect.
