description: We consider the star discrepancy of two-dimensional sequences made up as a hybrid between a Kronecker sequence and a perturbed Halton sequence in base 2, where the perturbation is achieved by a digital-sequence construction in the sense of Niederreiter whose generating matrix contains a periodic perturbing sequence of a given period length. Under the assumption that the Kronecker sequence involves a parameter with bounded continued fraction coefficients sharp discrepancy estimates are obtained. Furthermore, we study the problem from a metric point of view as well. Finally, we also present sharp general and tight metric bounds for certain lacunary trigonometric products which appear to be strongly related to these problems.

Year: 2018

description: The purpose of this study was to asses factors affecting employee turnover intention in nongovernmental organization in Addis Ababa, case of Strong Heart Development and Capacity Building Project. The study sought to determine why employees leave their organizations or companies. There is no doubt that turnover is costly; thus, it is important to understand what leads to such a phenomenon. Basic questions ie main factors for employees to leave their jobs, and the consequence of employee turnover on the organization's service were asked. Is it job satisfaction? Is it employee compensation? is it workload? Is it relationship between employee and management? Or career development? The study employed quantitative and qualitative research design methods. Since the number of the study population was manageable, the census method has been employed in the study and the entire population was the subject of study Thus, survey, interview, and document review were used to gather the data. Descriptive analysis and inferential statistics were employed in the analysis. Statistical Package for the Social Sciences (SPSS-) version 24 software was used in the analysis. Tables are used to present the data. Inferential statistics such as regression analysis was applied to determine the relative importance of each of the five variables with respect to employee turnover. Based on the data analysis the following findings were recorded. The main finding indicated that dissatisfaction with job, compensation, management& employee relation, workload, career development were some of the factors for employee turnover. The finding also indicated the following effects of turnover including loss of experienced and skilled employees, higher recruitment costs, and higher workload due to leavers. Recommendations is forwarded based on the findings so that managers revise salary and benefit packages, provide training and promotion opportunity, to keep the employee satisfied on their job and retained in the organization.

description: We consider the problem of geometric optimisation of the lowest eigenvalue of the Laplacian in the exterior of a compact planar set, subject to attractive Robin boundary conditions. Under either a constraint of fixed perimeter or area, we show that the maximiser within the class of exteriors of convex sets is always the exterior of a disk. We also argue why the results fail without the convexity constraint and in higher dimensions.

description: Raw food diets are one of several alternative eating plans that are becoming more and more appealing in western nations. The overall idea is to include a large number of raw foods in your diet; nevertheless, raw food eaters adhere to varying dietary guidelines. The subjects, who have been eating raw food for an average of 2.3 years, are made up of 230 male and 342 female individuals who are between the ages of 25 and 74. A thorough questionnaire and a food frequency questionnaire were utilized to gauge the individuals' eating habits and consumption in order to study their health behaviours. The study's raw food eaters were highly conscious of their health. The majority of them abstained from drinking, smoking, and regular exercise. Antinutrients and toxic substances in some raw foods should be correspondingly considered. Moreover, food safety is another point for concern in the consumption of raw food diets due to possible contamination by parasites, bacteria and soil-transmitted pathogens.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This basic aim of this paper to identify and investigate the effect of intrinsic and extrinsic rewards on employees' motivation in Ethio Telecom. As per the researcher made mini survey, the reward system of Ethio Telecom does not motivate its employees due to task in the job routine and limited, no job rotation and enlargement, limited career path and low opportunity to get promotion. The study followed mostly a quantitative and some qualitative approach to achieve the objectives of this study by describing and identifying the relation and effect of reward up on employee motivation. There were 11 independent variables were taken for this study. These are from intrinsic reward (Task and skill variety, Achievement, Opportunity for career growth, Responsibility, Autonomy, Job rotation and enlargement) ; from extrinsic reward ( Payment, Promotion, Working condition, Benefit package and recognition.). A standardized and well-structured questionnaire was used to measure the responses on a five level likert scale. Questionnaire was sent to 365 respondents in printed form and 324 collected and this is about 89%. The responses were analyzed using the Statistical Package for Social Sciences (SPSS) version 15.0 such as multiple regressions, The Pearson Product Moment correlation coefficient and descriptive statistics were used. For the descriptive statistics, graphical illustrations and table were used to provide information on key demographic variables in this study. The study confirmed existence of positive significant relationship between the total reward and employee motivation through correlation analysis and also it confirmed that total reward (intrinsic and extrinsic reward) has significant effect on employee motivation through multiple regression. Key word: Intrinsic Reward, Extrinsic Reward and Employee motivation.

description: Reconnections and interactions of filamentary coherent structures play a fundamental role in the dynamics of fluids, plasmas and nematic liquid crystals. In fluids, vortex reconnections redistribute energy and helicity among the length scales and induce fine-scale turbulent mixing. Unlike ordinary fluids where vorticity is a continuous field, in quantum fluids vorticity is concentrated into discrete (quantized) vortex lines turning vortex reconnections into isolated events, making it conceptually easier to study. Here we report experimental and numerical observations of three-dimensional quantum vortex interactions in a cigar-shaped atomic Bose-Einstein Condensate (BEC). In addition to standard reconnections, already numerically and experimentally observed in homogeneous systems away from boundaries, we show that double reconnections, rebounds and ejections can also occur as a consequence of the non-homogeneous, confined nature of the system.

Year: 2017

description: The value of human resource is an advantage to any organization and as a result training and development become a matter that has to be confronted by every organization. The practice of training in any organization is continuous process to refining the ability of employees. It is an effort to improve their performance, it is also an attempt made by the employer to provide opportunity for the employee to obtain enhanced job interrelated knowledge, skill and abilities. Therefore, the objective of the study was to assess the effect of training and development on employees' performance in African Union Commission. The research is based on primary and secondary data. The primary data was collected using self-administered questioners distributed to 138 respondents. The researcher used SPSS 20, descriptive statistics, correlation and regression analysis to analyze the data collected and to evaluate the relationship between the two variables. There is positive but low degree correlation between training need assessment and job performance (r = 0.351, p<0.001) and between training evaluation and employees job performance (r = 0.389, p<0.001). Employees whose training needs assessment were met were three times more likely to have good job performance compared with those whose training needs were not met; similarly, employees with positive perception towards training evaluation were four times more likely to exhibit better job performance compared with employees with negative perception. Thus the result of the study signifies that there is a positive and significant relationship between training and employee performance in the context of the African Union Commission. The researcher recommends that the AUC should incorporate needs assessment and evaluation into its training and development program. The study also recommend that in order to enhance employee performance the commission should continue its training program so that it can build and strengthen employee's competencies.

Human Norovirus (NV) is now considered the predominant cause of nonbacterial gastroenteritis cases worldwide. Despite the high frequency of infection in the community there still remains no vaccine or anti-viral treatment for NV infection attributed to the lack of suitable culture systems or animal models. The identification of a novel Murine Norovirus (MNV) in immune-deficient laboratory mice have greatly advanced our knowledge of the mechanisms involved norovirus (NoV) replication and pathogenesis. We examined the roles and interactions of several of the non-structural proteins, with focus on the predominantly uncharacterized non-structural protein three (NS3). Through expression studies, we identified that the NS3 protein induced the formation of distinct vesicle-like structures that did not colocalise with specific protein markers for cellular organelles. Instead these vesicular structures colocalised with membranes of high cholesterol content. Using a GFP-tagged MNV-NS3 we observed that these structures were highly motile, and their movement was dependent on intact microtubules. Our other key area of study was the innate immune system, and the methods employed by MNV (as a model for NV) to subvert and manipulate both the recognition and the response elicited during infection. We established that MNV has several avenues to combat the innate immune system. These studies identified that MNV prevents the nuclear translocation of transcription factors that contribute significantly to innate immune activation and function. We further interrogated these observations and found not one, but three candidates NS1-2, NS3 and NS4 when solely expressed were able to inhibit STAT1 nuclear translocation. Although such redundancy is rarely observed in virus replication, we believe this aids in the efficiency of the MNV to down-regulate the innate immune response, which it performs concurrently at various stages of the innate immune pathway to rapidly deplete host defences.

description: As the capacity of Solid-State Drives (SSDs) is constantly being optimised and boosted with gradually reduced cost, the SSD cluster is now widely deployed as part of the hybrid storage system in various scenarios such as cloud computing and big data processing. However, despite its rapid developments, the performance of the SSD cluster remains largely under-investigated, leaving its sub-optimal applications in reality. To address this issue, in this paper we conduct extensive empirical studies for a comprehensive understanding of the SSD cluster in diverse settings. To this end, we configure a real SSD cluster and gather the generated trace data based on some often-used benchmarks, then adopt analytical methods to analyse the performance of the SSD cluster with different configurations. In particular, regression models are built to provide better performance predictability under broader configurations, and the correlations between influential factors and performance metrics with respect to different numbers of nodes are investigated, which reveal the high scalability of the SSD cluster. Additionally, the cluster's network bandwidth is inspected to explain the performance bottleneck. Finally, the knowledge gained is summarised to benefit the SSD cluster deployment in practice.

description: We present a new finite-sample analysis of M-estimators of locations in $\mathbb{R}^d$ using the tool of the influence function. In particular, we show that the deviations of an M-estimator can be controlled thanks to its influence function (or its score function) and then, we use concentration inequality on M-estimators to investigate the robust estimation of the mean in high dimension in a corrupted setting (adversarial corruption setting) for bounded and unbounded score functions. For a sample of size $n$ and covariance matrix $Σ$, we attain the minimax speed $\sqrt{Tr(Σ)/n}+\sqrt{\|Σ\|_{op}\log(1/δ)/n}$ with probability larger than $1-δ$ in a heavy-tailed setting. One of the major advantages of our approach compared to others recently proposed is that our estimator is tractable and fast to compute even in very high dimension with a complexity of $O(nd\log(Tr(Σ)))$ where $n$ is the sample size and $Σ$ is the covariance matrix of the inliers. In practice, the code that we make available for this article proves to be very fast.

Using recent data on high energy neutrino from IceCube and Pierre Auger experiments we derive the upper-limits on neutrino flux from dark matter decay and constraints on dark matter parameter space. For the dark matter masses of order $10^8$ GeV the constraints derived are slightly stronger than those obtained for the same dark matter model using the high energy gamma-ray limits.

Creators: name: Na, Seunghoon

Publisher: name: Bank of Canada
Year: 2023

description: This paper investigates exchange rate dynamics in open economies by incorporating bounded rationality. We develop a small open-economy New Keynesian model with an incomplete asset market, wherein decision-makers possess limited foresight and can plan for only a finite distance into the future. The equilibrium dynamics depend on the degree of foresight and the decision-makers’ belief-updating behaviors that approximate continuation values at the end of their planning horizons. This limited foresight leads to persistent, non-monotonic forecast errors in the real exchange rate across time horizons and distinguishes between short- and long-term expectations. This framework hence provides a micro-foundation for understanding time-horizon variability in uncovered interest parity puzzles.
description: Cette étude s’intéresse aux mouvements de change dans des économies ouvertes où les agents disposent d’une rationalité limitée. Un modèle néo-keynésien d’économie ouverte avec un marché d’actifs incomplet est construit. Les décideurs y sont dotés d’un niveau de prévoyance limitée et ne peuvent planifier qu’à court terme à l’intérieur d’un horizon fini. La dynamique de l’équilibre dépend du degré de prévoyance des décideurs et de leurs comportements. À la fin de leurs horizons de planification, les décideurs réévaluent leurs croyances à l’égard de la valeur du taux de change de façon à déterminer approximativement des valeurs de continuation. Leur prévoyance limitée conduit à des erreurs de prévision non monotones et persistantes du taux de change réel, qui se répètent dans les différents horizons, et opère une distinction entre les anticipations à court et long terme. Le modèle jette donc les bases microéconomiques pour une compréhension de la variabilité des horizons temporels dans les énigmes entourant la parité des taux d’intérêt sans couverture du risque de change.

description: Many community detection algorithms have been developed to uncover the mesoscopic properties of complex networks. However how good an algorithm is, in terms of accuracy and computing time, remains still open. Testing algorithms on real-world network has certain restrictions which made their insights potentially biased: the networks are usually small, and the underlying communities are not defined objectively. In this study, we employ the Lancichinetti-Fortunato-Radicchi benchmark graph to test eight state-of-the-art algorithms. We quantify the accuracy using complementary measures and algorithms' computing time. Based on simple network properties and the aforementioned results, we provide guidelines that help to choose the most adequate community detection algorithm for a given network. Moreover, these rules allow uncovering limitations in the use of specific algorithms given macroscopic network properties. Our contribution is threefold: firstly, we provide actual techniques to determine which is the most suited algorithm in most circumstances based on observable properties of the network under consideration. Secondly, we use the mixing parameter as an easily measurable indicator of finding the ranges of reliability of the different algorithms. Finally, we study the dependency with network size focusing on both the algorithm's predicting power and the effective computing time.

description: We consider the chiral model of twisted bilayer graphene introduced by Tarnopolsky-Kruchkov-Vishwanath (TKV). TKV have proved that for inverse twist angles $α$ such that the effective Fermi velocity at the moiré $K$ point vanishes, the chiral model has a perfectly flat band at zero energy over the whole Brillouin zone. By a formal expansion, TKV found that the Fermi velocity vanishes at $α\approx .586$. In this work, we give a proof that the Fermi velocity vanishes for at least one $α$ between $.57$ and $.61$ by rigorously justifying TKV's formal expansion of the Fermi velocity over a sufficiently large interval of $α$ values. The idea of the proof is to project the TKV Hamiltonian onto a finite dimensional subspace, and then expand the Fermi velocity in terms of explicitly computable linear combinations of modes in the subspace, while controlling the error. The proof relies on two propositions whose proofs are computer-assisted, i.e., numerical computation together with worst-case estimates on the accumulation of round-off error which show that round-off error cannot possibly change the conclusion of the computation. The propositions give a bound below on the spectral gap of the projected Hamiltonian, an Hermitian $80 \times 80$ matrix whose spectrum is symmetric about $0,$ and verify that two real 18th order polynomials, which approximate the numerator of the Fermi velocity, take values with definite sign when evaluated at specific values of $α$. Together with TKV's work our result proves existence of at least one perfectly flat band of the chiral model.

description: A finales del siglo XIX y principios del siglo XX en la costa norte de Colombia ocurrió un fenómeno migratorio que fortaleció las sociabilidades y economía de ciudades como Barranquilla o Cartagena. De este fenómeno migratorio resaltamos la participación de un grupo proveniente de oriente medio que se destaca a lo largo del tiempo como un constante contribuyente a las dinámicas enomicas, sociales y políticas de la región caribe. Sus luchas como población extranjeras, sus logros como y empresarios, sus estrategias como comerciantes y sus avances como seres humanos han sido vistos como virtuosos a lo largo que se ha escrito sobre ellos en general una comunidad que aportó y aún siguen vigente en la escena socio-politica de la región.

description: We introduce a dynamical Mordell-Lang-type conjecture for coherent sheaves. When the sheaves are structure sheaves of closed subschemes, our conjecture becomes a statement about unlikely intersections. We prove an analogue of this conjecture for affinoid spaces, which we then use to prove our conjecture in the case of surfaces. These results rely on a module-theoretic variant of Strassman's theorem that we prove in the appendix.

description: Se elaboró un yogur descremado utilizando leche en polvo descremada, adicionado con aceite esencial de Flor de Jamaica. Dicho aceite esencial se obtuvo mediante la técnica de extracción por arrastre de vapor. A éste aceite esencial se le realizaron diversos análisis o pruebas químicas, tales como índice de refracción, índice de acidez, índice de yodo, y dos pruebas químicas para la determinación de su capacidad antioxidante, DPPH ó método del 2,2 difenil-1-picrilhidrazilo y TBA ó método del ácido tiobarbitúrico, por triplicado. Una vez elaborado el yogurt se le practicaron las siguientes pruebas fisicoquímicas: Porcentaje de grasa, proteína, sólidos totales, densidad y acidez. Se prepararon yogures con concentraciones de 50, 100 y 150 ppm de aceite esencial extraído de la flor de Jamaica. A los tres yogures se le realizaron pruebas de capacidad antioxidante mediante el método de DPPH, a los días 1, 6, 11, y 16. En donde se encontró una alta capacidad antioxidante al día 1, y con el pasar de los días ésta fue disminuyendo paulatinamente. Adicional a esto, 20 panelistas no entrenados realizaron un test de evaluación sensorial al yogur con las diferentes concentraciones, quienes lo caracterizaron con 4 parámetros: color, sabor, textura y aceptabilidad general, resultando como el más agradable en cuanto al color el yogur con 150 ppm de aceite esencial de flor de Jamaica, y en cuanto al sabor, textura y aceptabilidad general el yogur con 100 ppm de aceite esencial de flor de Jamaica. Luego se recogieron muestras del yogurt, para así realizarles las pruebas microbiológicas establecidas por el ministerio de protección social, tales como Coliformes totales, fecales y hongos y levaduras, resultando este producto como apto para el consumo humano. Así mismo le fue practicada la prueba de viscosidad cuyo resultado fue de 740 Cp. Esto se hizo con el objetivo de obtener un yogurt con propiedad funcional (antioxidante), adicionado con aceite esencial de flor de Jamaica, el cual tuvo efectividad en todos los tratamientos, ya que su capacidad antioxidante se incrementó dependiendo del aumento de la concentración del antioxidante o aceite esencial. En la evaluación de la capacidad antioxidante mediante el método del DPPH, el yogur con concentración de 150 ppm en aceite esencial de flor de Jamaica presentó un porcentaje de captación de radicales libres de 100% en el primer día, 33,33% al sexto día, 23,81% al décimo primer día y 7,14% al décimo sexto día.

description: The main intention of this project work is to assess and evaluate critically its status, performance and problems of Ethio telecom's expansion project implementation, monitoring and evaluations process. The study was based on primary data source collected from the Ethio telecom infrastructure expansion project teams and secondary data collected from company websites and project materials. The researcher used descriptive research design to describe the performance and challenges of telecom expansion project and for the purpose of triangulation, quantitative and qualitative approaches was utilized. This means descriptive method of data analysis was employed via using statistical software (SPSS) to describe the frequency, percentage, mean, and standard deviation of the actual performance status of the Ethio telecom expansion project against the target, and challenges faced by this company while implementing, monitoring and evaluating process TEP project sites. Based on the information gathered from respondents (questionnaire and interview results) different challenges observed during expansion project that broadly categorized to internal and external challenges

Spin-Orbit Dimers and Non-Collinear Phases in $d^1$ Cubic Double Perovskites

description: We formulate and study a spin-orbital model for a family of cubic double perovskites with $d^1$ ions occupying a frustrated fcc sublattice. A variational approach and a complimentary analytical analysis reveal a rich variety of phases emerging from the interplay of Hund's and spin-orbit couplings (SOC). The phase digram includes non-collinear ordered states, with or without net moment, and, remarkably, a large window of a non-magnetic disordered spin-orbit dimer phase. The present theory uncovers the physical origin of the unusual amorphous valence bond state experimentally suggested for Ba$_2B$MoO$_6$ ($B$=Y,Lu), and predicts possible ordered patterns in Ba$_2B$OsO$_6$ ($B$=Na,Li) compounds.
