description: We develop a stochastic description of small-field inflationary histories with a graceful exit in a random potential whose Hessian is a Gaussian random matrix as a model of the unstructured part of the string landscape. The dynamical evolution in such a random potential from a small-field inflation region towards a viable late-time de Sitter (dS) minimum maps to the dynamics of Dyson Brownian motion describing the relaxation of non-equilibrium eigenvalue spectra in random matrix theory. We analytically compute the relaxation probability in a saddle point approximation of the partition function of the eigenvalue distribution of the Wigner ensemble describing the mass matrices of the critical points. When applied to small-field inflation in the landscape, this leads to an exponentially strong bias against small-field ranges and an upper bound $N\ll 10$ on the number of light fields $N$ participating during inflation from the non-observation of negative spatial curvature.

description: The completeness of some classical statistical mechanical (SM) models is a recent result that has been developed by quantum formalism for the partition functions. In this paper, we consider a 2D classical $ϕ^4$ filed theory whose completeness has been proved in [V. Karimipour and et al, Phys. Rev. A 85, 032316]. We give a general systematic proof for the completeness of such a model where, by a few simple steps, we show how the partition function of an arbitrary classical field theory can be derived from a 2D classical $ϕ^4$ model. To this end, we start from various classical field theories containing models on arbitrary lattices and also $U(1)$ lattice gauge theories. Then we convert them to a new classical field model on a non-planar bipartite graph with imaginary kinetic terms. After that, we show that any polynomial function of the field in the corresponding Hamiltonian can approximately be converted to a $ϕ^4$ term by adding enough numbers of vertices to the bipartite graph. In the next step, we give a few graphical transformations to convert the final non-planar graph to a 2D rectangular lattice. We also show that the number of vertices which should be added grows polynomially with the number of vertices in the original model.

The Effect of organizational culture on organizational effectiveness with special reference to Ethiopian Revenues and Customs Authority
Creators: name: Abdulkadir, Rahma
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Even though there is an assumption that organizational culture is one variable which can affect an organization's function but there are few studies explicitly discuss the effect it has on organizational effectiveness. The main purpose of this study was to examine four traits of organizational culture; involvement, consistency, adaptability and mission and how they affect organizational effectiveness in the case of Ethiopian Revenues and Customs Authority (ERCA). For the study the researcher deployed explanatory research design and stratified sampling using the four sectors of ERCA functions. Proportion to population size method was used to distribute the sample in each stratum. The data had been gathered through structured questionnaire from 125 current employees of ERCA and an in-depth interview with directors in ERCA. The collected data were analyzed using statistical package for social science (SPSS) version 20. Descriptive statistics/frequency distribution and tables were used. This study takes place through two methods; the qualitative provided an explanatory analysis of management perception on the overall effect of organizational culture on ERCA's organizational effectiveness. And the quantitative study results show the predictive value of the four traits on the four indicators of organizational effectiveness of ERCA especially on employee satisfaction and organizational commitment. The research also shows that if employees are committed and share the same norms and values as per the organization, it could increase the effectiveness towards achieving the organizational goals. The study suggested that an emphasis should be given on ERCA's involvement, adaptability and consistency practices in order to enhance the effectiveness of employees' satisfaction and commitment and customers' satisfaction.

description: The uncertainty principle is considered to be one of the most striking features in quantum mechanics. In the textbook literature, uncertainty relations usually refer to the preparation uncertainty which imposes a limitation on the spread of measurement outcomes for a pair of non-commuting observables. In this work, we study the preparation uncertainty for the angular momentum, especially in the spin-1/2 representation. We derive uncertainty relations encompassing the triple components of angular momentum, and show that compared with the relations involving only two components, a triple constant $2/\sqrt{3}$ often arises. Intriguingly, this constant is the same for the position and momentum case. Experimental verification is carried out on a single spin in diamond, and the results confirm the triple constant in a wide range of experimental parameters.

description: We study analytic continuations of holographic renormalization group (RG) flows beyond their infrared (IR) fixed points. Such "trans-IR" flows are a natural framework for describing physics inside of black holes. First, we construct a monotonic holographic $a$-function which counts degrees of freedom along a trans-IR flow. Using this function, we argue that the degrees of freedom "thin out" and vanish when flowing to a trans-IR endpoint, represented by a Kasner singularity. We then recast well-studied quantum information probes in the language of trans-IR flows, finding that entanglement and complexity from volume generally fail to fully probe the trans-IR while 2-point correlations and complexity from action generally do so in a complementary manner.

description: It has been argued that the recently detected ring-down gravity waveforms could be indicative only of the presence of light rings in a horizonless object, such as a surgical Schwarzschild wormhole, with the frequencies differing drastically from those of the horizon quasinormal mode frequencies $ω_{\text{QNM}}$ at late times. While the possibility of such a horizonless alternative is novel by itself, we show by the example of Ellis-Bronnikov wormhole that the differences in $ω_{\text{QNM}}$ in the eikonal limit (large $l$) need not be drastic. This result will be reached by exploiting the connection between $ω_{\text{QNM}}$ and the Bozza strong field lensing parameters. We shall also show that the lensing observables of the Ellis-Bronnikov wormhole can also be very close to those of a black hole (say, SgrA$^{\ast }$ hosted by our galaxy) of the same mass. This situation indicates that the ring-down frequencies and lensing observables of the Ellis-Bronnikov wormhole can remarkably mimic those of a black hole. The constraint on wormhole parameter $γ$ imposed by experimental accuracy is briefly discussed. We also provide independent arguments supporting the stability of the Ellis-Bronnikov wormhole proven recently.

description: Knapsack problem (KP) is a representative combinatorial optimization problem that aims to maximize the total profit by selecting a subset of items under given constraints on the total weights. In this study, we analyze a generalized version of KP, which is termed the generalized multidimensional knapsack problem (GMDKP). As opposed to the basic KP, GMDKP allows multiple choices per item type under multiple weight constraints. Although several efficient algorithms are known and the properties of their solutions have been examined to a significant extent for basic KPs, there is a paucity of known algorithms and studies on the solution properties of GMDKP. To gain insight into the problem, we assess the typical achievable limit of the total profit for a random ensemble of GMDKP using the replica method. Our findings are summarized as follows: (1) When the profits of item types are normally distributed, the total profit grows in the leading order with respect to the number of item types as the maximum number of choices per item type $x^{\rm max}$ increases while it depends on $x^{\rm max}$ only in a sub-leading order if the profits are constant among the item types. (2) A greedy-type heuristic can find a nearly optimal solution whose total profit is lower than the optimal value only by a sub-leading order with a low computational cost. (3) The sub-leading difference from the optimal total profit can be improved by a heuristic algorithm based on the cavity method. Extensive numerical experiments support these findings.

The Constraints Of Line Managers In Effectively Implementing Hr Practices A Case Study In The Economic Commission For Africa
Creators: name: Eshet, Fetsoum
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The purpose of this paper was to analyze the constraints of line supervisors in the implementation of HR practices by taking the case of Economic Commission for Africa. In order to determine which factors constraints effective HRM implementation, it was beneficial to collect data from multiple stakeholders for a more reliable result based on the AMO theory. The effectiveness of line supervisors had been measured using data collected from line supervisors and their subordinates with a sample of 110 subordinates and 42 line managers in Economic Commission for Africa. A model that describes how devolving HR practices to the line influences the effective implementation was developed by Bos-Nehles (2006) and the study make a use of it to collect the relevant data. The perception of line supervisors on their own effectiveness was investigated in terms of the three factors of the AMO theory, which are ability, motivation and opportunity. The study incorporated the AMO theory into the model, which is operationalized in terms of five constraints: competence, desire, time capacity, support and policy & procedures. The perception of employees on the effectiveness of their line managers was investigated based on their responses of the HR practices implemented by line supervisors in the organization, namely: personnel administration, staffing, recruitment and selection, training, career development and performance management. We found competence, support, policy and procedures to be the best predictors of a line manager's HR practices effective implementation. The absence of one of the three factors can be the constraint to the effective implementation of HR practices by line managers. Motivation did not have significant direct effect on effective HR practices implementation but the relationship needs further attention. Opportunity did moderately affect the HRM implementation effectiveness. However, the results are not entirely reliable due to the small sample. Further research on additional stakeholders should determine whether different stakeholders disagree in constraints concerning the effective implementation of HR practices.

description: In millimeter wave cellular communication, fast and reliable beam alignment via beam training is crucial to harvest sufficient beamforming gain for the subsequent data transmission. In this paper, we establish fundamental limits in beam-alignment performance under both the exhaustive search and the hierarchical search that adopts multi-resolution beamforming codebooks, accounting for time-domain training overhead. Specifically, we derive lower and upper bounds on the probability of misalignment for an arbitrary level in the hierarchical search, based on a single-path channel model. Using the method of large deviations, we characterize the decay rate functions of both bounds and show that the bounds coincide as the training sequence length goes large. We go on to characterize the asymptotic misalignment probability of both the hierarchical and exhaustive search, and show that the latter asymptotically outperforms the former, subject to the same training overhead and codebook resolution. We show via numerical results that this relative performance behavior holds in the non-asymptotic regime. Moreover, the exhaustive search is shown to achieve significantly higher worst-case spectrum efficiency than the hierarchical search, when the pre-beamforming signal-to-noise ratio (SNR) is relatively low. This study hence implies that the exhaustive search is more effective for users situated further from base stations, as they tend to have low SNR.

Enhancing a slow and weak optomechanical nonlinearity with delayed quantum feedback

description: One of the central goals of quantum optics is to generate large interactions between single photons. Light interacting with motion in an optomechanical system can sense minute fluctuations in displacement, and also impart a force via radiation pressure. Taken together, these two effects mean that two photons can "sense" each other's presence in an interaction mediated by motion. It is accepted that for an optomechanical system to mediate strong interactions between single photons, the mechanical system must respond before the photon is lost ($ω_m > κ$), and the radiation pressure force must generate a displacement large enough to change the optical properties of the system ($g_0 > κ$). The challenge of achieving this "vacuum strong coupling" has prevented experiments from demonstrating single-photon interactions. In this work we show that by adding a coherent feedback channel to a slow mechanical system ($ω_m < κ$) that is weakly nonlinear ($g_0 < κ$), two spatially separated single photons can be made to effectively interact with each other deterministically through the mechanical motion of a resonator. To numerically analyze our system, we must solve Schrödinger's equation for the state of an optomechanical system coupled to a long waveguide feeback channel. We implement a matrix product state approach to keep track of and evolve the complete quantum state of the system in an efficient way. We analyze the process semiclassically and then solve the full quantum dynamics numerically to find a cross-over between the semiclassical and quantum regimes of optomechanics. Finally we analyze the experimental prospects for implementing this protocol.

Year: 2019

description: Utilization of forest wood raw materials for particle board production has resulted in deforestation, loss of habitat for millions of species, climate change and raw material competition. Therefore, the use of non woody ligno-cellulosic raw materials is a good choice for particle board production. In this study aloe and sisal stem fibers were used as a blend and mixed with urea-formaldehyde (UF) resin for particle board production. First the aloe and sisal stems were collected form Adigrat and sun dried. The dried stems were then crushed into 3mm to 6mm in size. The particles were further reduced in size by grinding (0.5-2.5mm) and classified into different classes, i.e. very fine (250µm-475µm for both aloe and sisal fibers), fine (0.5-1.4 mm for aloe and 0.71-1.4mm for sisal fibers) and coarse (1.4-2.0 mm for aloe and 1.4-2.5 mm for sisal fibers), based on the requirement for production and analysis and stored on different containers until needed. The fibers were then analyzed for their moisture, ash, extractive, hemicellulose, lignin and cellulose content. FTIR analysis was also performed for identification of the functional groups present in the aloe and sisal stem fibers. After analysis of raw materials, three layered particleboards were produced using 22cm by 22 cm mould using coarse particles (60%) as core layers and fine particles (40%) as surface layers. Design expert 11 software was used for design of the experiments and statistical analysis of the results.17 different boards were produced by varying the aloe to sisal ratio (30-60%), resin loading rate (10-15%) and pressing pressure(150-200 bar) at pressing temperature of 155 C and press time of 14 minutes. The physical (moisture content, water absorption and thickness swelling) and mechanical (Modulus of rupture (MOR), Modulus of elasticity (MOE) and Internal bond (IB)) properties of the boards were investigated and compared with the Ethiopian standards for particle board. The results of the mechanical properties test showed that the particles boards have an average values of 11.267 MPa MOR,1686.34 MPa MOE and 0.417 MPa IB. The analysis of physical properties also showed that the particle boards have average values of 76.95% water absorption and 62% thickness swelling after 2 and 24hrs of immersion in water bath. The maximum results for MOR, MOE and IB were 12.42MPa, 1830.13MPa and 0.505Mpa, respectively. These values were observed at 45% of aloe to sisal ratio, 12.5% of resin loading and 175 bar pressing pressure. The minimum values for WA and TS were 47.15% and 61.9% ,respectively. These values were observed at 45% of aloe to sisal ratio, 15 % of resin loading and 200 bar pressing pressure. The final results of mechanical properties were compared with the Ethiopian standards for particle boards and they were found satisfactory for general purpose use.

description: Sorting is at the core of many database operations, such as index creation, sort-merge joins, and user-requested output sorting. As GPUs are emerging as a promising platform to accelerate various operations, sorting on GPUs becomes a viable endeavour. Over the past few years, several improvements have been proposed for sorting on GPUs, leading to the first radix sort implementations that achieve a sorting rate of over one billion 32-bit keys per second. Yet, state-of-the-art approaches are heavily memory bandwidth-bound, as they require substantially more memory transfers than their CPU-based counterparts. Our work proposes a novel approach that almost halves the amount of memory transfers and, therefore, considerably lifts the memory bandwidth limitation. Being able to sort two gigabytes of eight-byte records in as little as 50 milliseconds, our approach achieves a 2.32-fold improvement over the state-of-the-art GPU-based radix sort for uniform distributions, sustaining a minimum speed-up of no less than a factor of 1.66 for skewed distributions. To address inputs that either do not reside on the GPU or exceed the available device memory, we build on our efficient GPU sorting approach with a pipelined heterogeneous sorting algorithm that mitigates the overhead associated with PCIe data transfers. Comparing the end-to-end sorting performance to the state-of-the-art CPU-based radix sort running 16 threads, our heterogeneous approach achieves a 2.06-fold and a 1.53-fold improvement for sorting 64 GB key-value pairs with a skewed and a uniform distribution, respectively.

description: A single channel 1.5GS/s 8-bit pipelined-SAR ADC utilizes a novel output level shifting (OLS) settling technique to reduce the power and enable low-voltage operation of the dynamic residue amplifier. The ADC consists of a 4-bit first stage and a 5-bit second stage, with 1-bit redundancy to relax the offset, gain, and settling requirements of the first stage. Employing the OLS technique allows for an inter-stage gain of ~4 from the dynamic residue amplifier with a settling time that is only 28% of a conventional CML amplifier. The ADC's conversion speed is further improved with the use of parallel comparators in the two asynchronous stages. Fabricated in a 14nm FinFET technology, the ADC occupies 0.0013mm2 core area and operates with a 0.8V supply. 6.6-bit ENOB is achieved at Nyquist while consuming 2.4mW, resulting in an FOM of 16.7fJ/conv.-step.

description: The purpose of this research was to examine the determinant factors affecting employees' job performance in the case of Wegagen Bank S.C. In the Implementing of these internal practices the bank faced a problem of formal follow up after training was conducted; inequitable salary and unfair promotion; and limitation in participating employee in decision making. Data was gathered from Head Office and 36 Addis Ababa city branches. The research is quantitative research approach using Cross sectional survey method and the researcher have used sample size determination table and stratified sampling method was employed to select the sample from each stratum to make the sample more representative of the population. Descriptive and inferential statistics of correlation and regression analysis were used to analyze the empirical data. Primary data were collected using five Point Likert-Scale questionnaires 191 responses were properly filled and returned. SPSS was used to analyze empirical data collected through the close ended questionnaire. The independent variables are training, motivation, leadership, organizational culture and working environment whereas the dependent variable is employees' job performance. The mean, frequency and percentile of the dependent and independent variables were computed and interpreted. Pearson correlation Coefficient (r) was used to determine the relationship between each independent variable with the dependent variable. The finding results indicated that the mean value for motivation (mean=2.86),leadership (mean=2.94), organizational culture (mean=2.99), and working environment (mean=2.87) were below average which indicate that there was limitation in implementing this practice in Wegagen Bank. The correlation result indicated that there were positive relationship between all of independent variables and the dependent variable, rejecting all null hypotheses. This implies that any increase or decrease on the independent variable will bring corresponding change on employees' job performance. And it's found that the independent variables has a 30.1% influence on the dependent variable while the remaining 69.9% is influenced by factors which are not covered in this study. Hence, the Wegagen Bank should periodically review its practice on motivation, leadership, organizational culture, and working environment in order to improve the limitation and to identify its effectiveness on employees' job performance.

description: Superconductivity can be understood in terms of a phase transition from an uncorrelated electron gas to a condensate of Cooper pairs in which the relative phases of the constituent electrons are coherent over macroscopic length scales. The degree of correlation is quantified by a complex-valued order parameter, whose amplitude is proportional to the strength of the pairing potential in the condensate. Supercurrent-carrying states are associated with non-zero values of the spatial gradient of the phase. The pairing potential and several physical observables of the Cooper condensate can be manipulated by means of temperature, current bias, dishomogeneities in the chemical composition or application of a magnetic field. Here we show evidence of complete suppression of the energy gap in the local density of quasiparticle states (DOS) of a superconducting nanowire upon establishing a phase difference equal to pi over a length scale comparable to the superconducting coherence length. These observations are consistent with a complete collapse of the pairing potential in the center of the wire, in accordance with theoretical modeling based on the quasiclassical theory of superconductivity in diffusive systems. Our spectroscopic data, fully exploring the phase-biased states of the condensate, highlight the profound effect that extreme phase gradients exert on the amplitude of the pairing potential. Moreover, the sharp magnetic response observed near the onset of the superconducting gap collapse regime can be exploited to realize ultra-low noise magnetic flux detectors.

description: A specialization semilattice is a join semilattice together with a coarser preorder $ \sqsubseteq $ satisfying an appropriate compatibility condition. If $X$ is a topological space, then $(\mathcal P(X), \cup, \sqsubseteq )$ is a specialization semilattice, where $ x \sqsubseteq y$ if $x \subseteq Ky$, for $x,y \subseteq X$, and $K$ is closure. Specialization semilattices and posets appear as auxiliary structures in many disparate scientific fields, even unrelated to topology. For short, the notion is useful since it allows us to consider a relation of "being generated by" with no need to require the existence of an actual "closure" or "hull", which might be problematic in certain contexts. In a former work we showed that every specialization semilattice can be embedded into the specialization semilattice associated to a topological space as above. Here we describe the universal embedding of a specialization semilattice into an additive closure semilattice. We notice that a categorical argument guarantees the existence of universal embeddings in many parallel situations.

description: The electronic and optical properties of a GaAs quantum ring (QR) with few electrons in the presence of the Rashba spin-orbit interaction (RSOI) and the Dresselhaus spin-orbit interaction (DSOI) have been investigated theoretically. Configuration interaction (CI) method is employed to calculate the eigenvalues and eigenstates of the multiple-electron QR accurately. Our numerical results demonstrate that the symmetry breaking induced by the RSOI and DSOI leads to an anisotropic distribution of multi-electron states. The Coulomb interaction offers additional modulation of the electron distribution and thus the optical absorption indices in the quantum rings. By tuning the magnetic/electric fields and/or electron numbers in a quantum ring, one can change its optical property significantly. Our theory provides a new way to control multi-electron states and optical properties of QR by hybrid modulations or by electrical means only.

description: This paper aimed at investigating the effect of employee development program on job satisfaction and employee retention in commercial Bank of Ethiopia. This study used likert scale questionnaires. Four hypotheses were investigated using multiple regression and correlation coefficient techniques. The models considered the effect of mentoring, job rotation, career development, training methods, and operational knowledge of employee's on job satisfaction and employee retention. The study also sought the relationship of EDP of mentoring, job rotation, career development, training methods, and operational knowledge of employees on job satisfaction and employee retention. The study was carried out stratified random sampled techniques used in order to select participants out of the four districts offices in Addis Ababa area of CBE out of the total sample size of 315 employees 27 poorly, and inappropriate thus the researcher collect another data in order to make appropriate analysis. Simple random sampled was used for the selected employees by used first lottery system then nth. Both descriptive and inferential statistical was used to analyze the data. A Multiple Regression made to test the four hypothesis how well the EDP could predict job satisfaction and employee retention, correlation analysis used to see their relationship. The findings of this study highlight the fact that EDP are vital to employees and certainly influence and a positive relationship on job satisfaction and employee retention in the bank. CBE should provide some level of flexibility in order to deliver developmental program that appear to be important to the employees. Also, the bank should collaborate with universities and other academic institution for research on problems confronted them regarded job satisfaction and employee retention so as to derive the best solutions for their human resource development. In future, other researchers should undertake for the entire banks in the country assessed the practices that affect job satisfaction and employee retention. Also future studies should employ mixed methods in order to obtain greater insights into the specific EDP especially from the perspective of HR development of the entire banks in Ethiopia.Key words: Employee development program, job satisfaction, employee retention
Tensor networks for dynamic spacetimes

description: Existing tensor network models of holography are limited to representing the geometry of constant time slices of static spacetimes. We study the possibility of describing the geometry of a dynamic spacetime using tensor networks. We find it is necessary to give a new definition of length in the network and propose a definition based on the mutual information. We show that by associating a set of networks with a single quantum state and making use of the mutual information based definition of length, a network analogue of the maximin formula can be used to calculate the entropy of boundary regions.
