Elliptic flow as a probe for $ψ(2S)$ production mechanism in relativistic heavy ion collisions

Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: I discuss the elliptic flows of $ψ(2S)$ with different production mechanisms in $\sqrt{s_{NN}}=2.76$ TeV Pb-Pb collisions. If the final $ψ(2S)$s are mainly from the recombination of uncorrelated charm and anticharm quarks at $T\approx T_c$, charm and anticharm quarks will carry large collective flows of the bulk medium, which will be inherited by the regenerated $ψ(2S)$s. This indicates a larger elliptic flow of $ψ(2S)$ than that of $J/ψ$ which can be regenerated at $T\ge T_c$, $v_2^{ψ(2S)}>v_2^{J/ψ}$. However, if the final $ψ(2S)$s are mainly from the transitions of $J/ψ\rightarrow ψ(2S)$ caused by the color screening of QGP, its elliptic flow should be close to the elliptic flow of $J/ψ$, $v_2^{ψ(2S)}\sim v_2^{J/ψ}$. Therefore, $ψ(2S)$ elliptic flow is a sensitive probe for its production mechanisms in relativistic heavy ion collisions.

description: Constant-dimension codes with the maximum possible minimum distance have been studied under the name of partial spreads in Finite Geometry for several decades. Not surprisingly, for this subclass typically the sharpest bounds on the maximal code size are known. The seminal works of Beutelspacher and Drake \& Freeman on partial spreads date back to 1975, and 1979, respectively. From then until recently, there was almost no progress besides some computer-based constructions and classifications. It turns out that vector space partitions provide the appropriate theoretical framework and can be used to improve the long-standing bounds in quite a few cases. Here, we provide a historic account on partial spreads and an interpretation of the classical results from a modern perspective. To this end, we introduce all required methods from the theory of vector space partitions and Finite Geometry in a tutorial style. We guide the reader to the current frontiers of research in that field, including a detailed description of the recent improvements.

The Effectiveness Of Gender-Based Violence Projects In Combating Violence Against Women In Addis Ababa, Ethiopia: The Case Of Enhancing Psycho-Social Support And Economic Wellbeing Of Women Project
Creators: name: Tsegaye, Niat
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The aim of this research is to assess the effectiveness of GBV projects in combating violence against women in Addis Ababa, Ethiopia. In order to conduct this study, a project from AWSAD was considered. In addition, one of AWSAD's shelters was approached. The research is descriptive and mostly qualitative in nature. Four respondents from AWSAD's head office and ten women and children from the shelter were selected for semi structured interviews. In both qualitative and quantitative data analysis, the results have been presented and analyzed. It was found that combating GBV through prevention and response has been successful in reducing violence against women. It has been concluded and recommended that, even though the project has showed promising figures and feedbacks from project beneficiaries, more needs to be done to both prevent and respond to GBV.

description: The energy shift of a nucleon in a static periodic magnetic field is evaluated at second order in the external field strength in perturbation theory. It is shown that the measurement of this energy shift on the lattice allows one to determine the unknown subtraction function in the forward doubly virtual Compton scattering amplitude. The limits of applicability of the obtained formula for the energy shift are discussed.

Konfiguration und Durchsetzung von Sicherheitsspezifikationen mit Hilfe einer erweiterten Java-Laufzeitumgebung

Year: 2003
Subjects: subject: 004

description: Java bietet eine konfigurierbare Zugriffskontrolle, mit der ein Anwender oder sein Administrator in einer Sicherheitspolitik festlegen kann, welche Anwendung und welcher Benutzer auf welche Systemressourcen zugreifen darf. Allerdings kann in der Sicherheitspolitik nicht definiert werden, wie diese Zugriffe ausgeführt werden, ob dabei also Sicherheitsmechanismen wie Verschlüsselung oder Authentifizierung eingesetzt werden sollen; solche Dienste müssen bereits vom Anwendungs- oder Komponentenentwickler integriert werden. Dies hat mehrere Nachteile: Möchte der Anwender zusätzliche Sicherheitsmechanismen einsetzen, so ist er auf Anwendungen oder Komponenten angewiesen, von denen seine Sicherheitsziele berücksichtigt werden. Die Entwickler können sich nicht auf die Fachlichkeit konzentrieren, sondern müssen ebenso Sicherheitskonzepte kennen und korrekt anwenden. Die Anwendungskomponenten müssen daher die kryptographischen Schlüssel zur Initialisierung der eingesetzten Algorithmen kennen, was bei fehlerhaften Implementierungen oder unzureichendem Schutz der Schlüssel zu großen Sicherheitslücken führen kann. Aus diesen Gründen erscheint es vorteilhaft, wenn der Anwender in einer Sicherheitspolitik auch solche Algorithmen vorschreiben könnte und die Java-Laufzeitumgebung diese bei Ressourcenzugriffen unabhängig von der Anwendung ausführen würde. In dieser Arbeit wird daher eine Lösung zur Konfiguration und Durchsetzung von Sicherheitsspezifikationen mit Hilfe einer erweiterten Java-Laufzeitumgebung vorgestellt. Die Lösung besteht zum einen aus einer Erweiterung der Java Virtual Machine, die eine Integration zusätzlicher Funktionalität in bestehende Klassen der Java-Klassenbibliothek ohne deren Veränderung durch Wrapping ermöglicht, und zum anderen aus der konfigurierbaren und erweiterbaren Bibliothek JSEC (Java Security Enforcement and Configuration), die bei Ressourcenzugriffen zusätzliche Sicherheitsdienste anwendet, die in einer Sicherheitspolitik spezifiziert werden können. Diese Bibliothek besitzt eine Architektur, die eine Erweiterung um weitere Ressourcentypen, um neue Sicherheitsdienste und um zusätzliche Bedingungen für die Anwendung dieser Dienste vorsieht und eine Zusammenarbeit solcher, auch unabhängig voneinander entwickelter Bestandteile ermöglicht. Die Standardimplementierung dieser Bausteine ermöglicht eine Anwendung kryptographischer Algorithmen und eine Protokollierung bei Netzwerk- und Dateizugriffen; die Sicherheitspolitik wird in XML-Dokumenten spezifiziert. Dazu werden Konzepte und Implementierungen der existierenden Java-Sicherheitsbibliotheken JCA, CE, JSSE, JAAS und des Security Managers eingesetzt und deren Erweiterbarkeit ebenfalls unterstützt.

description: We investigate a class of Young diagrams growing via the addition of unit cells and satisfying the constraint that the height difference between adjacent columns $\geq r$. In the long time limit, appropriately re-scaled Young diagrams approach a limit shape that we compute for each integer $r\geq 0$. We also determine limit shapes of `diffusively' growing Young diagrams satisfying the same constraint and evolving through the addition and removal of cells that proceed with equal rates.

description: Semiconductors are by now well-established targets for direct detection of MeV to GeV dark matter via scattering off electrons. We show that semiconductor targets can also detect significantly lighter dark matter via an absorption process. When the dark matter mass is above the band gap of the semiconductor (around an eV), absorption proceeds by excitation of an electron into the conduction band. Below the band gap, multi-phonon excitations enable absorption of dark matter in the 0.01 eV to eV mass range. Energetic dark matter particles emitted from the sun can also be probed for masses below an eV. We derive the reach for absorption of a relic kinetically mixed dark photon or pseudoscalar in germanium and silicon, and show that existing direct detection results already probe new parameter space. With only a moderate exposure, low-threshold semiconductor target experiments can exceed current astrophysical and terrestrial constraints on sub-keV bosonic dark matter.

The Interface between Strategic Human Resource Management Principles Implementation and Organizational Performance: A case study of ethio telecom
Creators: name: Wendmu, Mahelet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Strategic Human Resource Management (SHRM) is an approach that defines how the organization's goals will be achieved through people by means of HR strategies, integrated HR policies and practices. This paper examines the interface between strategic human resource management principles implementation and organizational performance of ethio telecom using data collected from 291 management employees of ethio telecom working in the head quarter. The study is mixed in its approach and explanatory in its design. The analysis of the descriptive statistics revealed that the respondents have moderate agreement regarding the implementation of SHRM principles in ethio telecom i.e vertical (internal) alignment of ethio telecom's HRM strategies, policies and practices with the company vision, mission and strategies, the consistency and congruence of ethio telecom HRM policies and practices (horizontal alignment), the role of HRM unit in playing its strategic role and the role of line managers in playing their HRM role. In addition to this, the respondents have shown moderate agreement on the overall performance of ethio telecom in the past three and half years that is measured in the key perspectives defined based on balanced scorecard approach i.e customer perspective, finance perspective, internal process perspective and learning and development perspective. The correlation analysis results have shown that there is a high positive correlation in between overall performance of ethio telecom and ET HRM strategies, policies and practices vertical alignment with VMS & ET HRM unit strategic role and there is medium positive correlation between ethio telecom overall performance and ET HRM policies and practices consistency and congruence (horizontal alignment) & ET LM HRM role. The role of HRM unit in playing its strategic role have strong positive correlation with the company overall performance. The regression model has revealed that implementation of SHRM principles explains 37.5% of ethio telecom performance. The mediation analysis has proved that HR plays a partial mediation role in enabling the implementation of SHRM principles and impacting the organizational performance positively. From the analysis of the study, it can be concluded that the implantation of SHRM principles significantly explains the company performance. Hence, ethio telecom needs to give significant attention for VII implementation of SHRM principles. Given there are no studies conducted in ethio telecom on this topic, this study may be a herald for a much rigorous study

description: In many felds of technological developments, understanding and controlling material fatigue is an important point of interest. This article is concerned with statistical modeling of the damage process of prestressed concrete under low cyclic load. A crack width process is observed which exhibits jumps with increasing frequency. Firstly, these jumps are modeled using a Poisson process where two intensity functions are presented and compared. Secondly, based on the modeled jump process, a stochastic process for the crack width is considered through a stochastic differential equation (SDE). It turns out that this SDE has an explicit solution. For both modeling steps, a Bayesian estimation and prediction procedure is presented.

description: This work presents transport coefficients of electrons (bulk drift velocity, longitudinal diffusion coefficient, and effective ionization frequency) in CO2 measured under time-of-flight conditions over a wide range of the reduced electric field, 15Td <= E/N <= 2660Td in a scanning drift tube apparatus. The data obtained in the experiments are also applied to determine the effective steady-state Townsend ionization coefficient. These parameters are compared to the results of previous experimental studies, as well as to results of various kinetic computations: solutions of the electron Boltzmann equation under different approximations (multiterm and density gradient expansions) and Monte Carlo simulations. The experimental data extend the range of E/N compared with previous measurements and are consistent with most of the transport parameters obtained in these earlier studies. The computational results point out the range of applicability of the respective approaches to determine the different measured transport properties of electrons in CO2. They demonstrate as well the need for further improvement of the electron collision cross section data for CO2 taking into account the present experimental data.

description: We present a collision model for phase-resolved Direct Numerical Simulations of sediment transport that couple the fluid and particles by the Immersed Boundary Method. Typically, a contact model for these types of simulations comprises a lubrication force for particles in close proximity to another solid object, a normal contact force to prevent particles from overlapping, and a tangential contact force to account for friction. Our model extends the work of previous authors to improve upon the time integration scheme to obtain consistent results for particle-wall collisions. Furthermore, we account for polydisperse spherical particles and introduce new criteria to account for enduring contact, which occurs in many sediment transport situations. This is done without using arbitrary values for physically-defined parameters and by maintaining the full momentum balance of a particle in enduring contact. We validate our model against several test cases for binary particle-wall collisions as well as the collective motion of a sediment bed sheared by a viscous flow, yielding satisfactory agreement with experimental data by various authors.

description: This study aims to assess the Effect of Project Monitoring and Controlling Practice on Project Success in the case of Ethiopian Airlines Digital PMO. To achieve the objective of the study Explanatory and Descriptive research design were used. As a result the researcher mainly deployed quantitative type of research design. Data for the assessment are obtained through five point Likert scale based questionnaire from 43 selected respondents. Collected data was analyzed by using descriptive analysis, correlation and regression analysis using SPSS version 20.0. The results of the collected data shows that there is good project monitoring and controlling practice in the organization, however relatively there is weak project change control process in the PMO. Results also revealed that Pearson correlation between project documentation processes was a moderate with project success, and Pearson correlation between project progress report process and project change control process was a strong with project success. Regression results shows that there was 60.7% of the change in project success was attributed to the combine effect of the independent variables in the model (project progress report, change control and documentation). The overall project Monitoring and Controlling process groups have strong impact on project success, which means that high project monitoring and controlling had likely to generate higher level of project success. To be more successful in projects, the study recommend that organization must focus on project monitoring and controlling practice especially on the project progress follow up and project change control area as they have significant impact on the project success.

description: Accretion is known to be dramatically variable across many young objects, from subtle variability on long periods to rapid dramatic outbursts in EXor and FUor objects. Such changes greatly influence and sculpt the characteristics and morphology of inner disks. present NIR interferometric results of two objects which are undergoing enhanced accretion rates. FU Ori, the archetypal outbursting star exhibiting boundary layer accretion and a viscously heated inner disk; and SU Aur, where a late infall event triggers strong disk winds from the inner disk, obscuring the central star. This work highlights the power of high angular resolution observations in diagnosing accretion and ejection processes in young stars.

description: Theta series for lattices with indefinite signature $(n_+,n_-)$ arise in many areas of mathematics including representation theory and enumerative algebraic geometry. Their modular properties are well understood in the Lorentzian case ($n_+=1$), but have remained obscure when $n_+\geq 2$. Using a higher-dimensional generalization of the usual (complementary) error function, discovered in an independent physics project, we construct the modular completion of a class of `conformal' holomorphic theta series ($n_+=2$). As an application, we determine the modular properties of a generalized Appell-Lerch sum attached to the lattice $A_2$, which arose in the study of rank 3 vector bundles on $\mathbb{P}^2$. The extension of our method to $n_+>2$ is outlined.

description: In this paper we study the domain of stable processes, stable-like processes and more general pseudo- and integro-differential operators which naturally arise both in analysis and as infinitesimal generators of Lévy- and Lévy-type (Feller) processes. In particular we obtain conditions on the symbol of the operator ensuring that certain (variable order) Hölder and Hölder-Zygmund spaces are in the domain. We use tools from probability theory to investigate the small-time asymptotics of the generalized moments of a Lévy or Lévy-type process $(X_t)_{t \geq 0}$, \begin{equation*} \lim_{t \to 0} \frac 1t\left(\mathbb{E}^x f(X_t)-f(x)\right), \quad x\in\mathbb{R}^d, \end{equation*} for functions $f$ which are not necessarily bounded or differentiable. The pointwise limit exists for fixed $x \in \mathbb{R}^d$ if $f$ satisfies a Hölder condition at $x$. Moreover, we give sufficient conditions which ensure that the limit exists uniformly in the space of continuous functions vanishing at infinity. As an application we prove that the domain of the generator of $(X_t)_{t \geq 0}$ contains certain Hölder spaces of variable order. Our results apply, in particular, to stable-like processes, relativistic stable-like processes, solutions of Lévy-driven SDEs and Lévy processes.

description: We extend a result on renormalized oscillation theory, originally derived for Sturm-Liouville and Dirac-type operators on arbitrary intervals in the context of scalar coefficients, to the case of general Hamiltonian systems with block matrix coefficients. In particular, this contains the cases of general Sturm-Liouville and Dirac-type operators with block matrix-valued coefficients as special cases. The principal feature of these renormalized oscillation theory results consists in the fact that by replacing solutions by appropriate Wronskians of solutions, oscillation theory now applies to intervals in essential spectral gaps where traditional oscillation theory typically fails.

description: The main objective of the study was to examine effects of leadership style on employee engagement. A total of 242 questioner were distributed out of this 239 respondents completed the MLQ and Gallup 12 item survey questionnaires. The study employed both Descriptive and explanatory research design. Primary and secondary sources of data were used in the study. In addition the study employed a stratified random sampling method to collect data from professional employees of commercial bank of Ethiopia found in ten Grade 4 branches under East Addis Ababa District. The collected data was analysed using SPSS software version 22. In addition, to analyse the collected data descriptive statistics (frequencies means & standard deviations), correlation & regression analysis were used. The descriptive statistics result showed that the employees exhibited a great extentlevel of engagement and the dominant leadership style at the organization is transactional leadership. The Correlation and regression analysis also showed there is a relationship between the effect of leadership style (Independents Variables) and Employees Engagement (Dependent Variable).In addition the result of peerson correlation revealed that significant positive relationship is found between Leadership style and Employee Engagement. At last the researcher suggested that since the effect of leadership style has a significant effect on employee engagement, it is recommended that using various leadership styles will bring more effectiveness and enhance employee performance

description: One of the fundamental questions of theoretical cosmology is whether the universe can undergo a non-singular bounce, i.e., smoothly transit from a period of contraction to a period of expansion through violation of the null energy condition (NEC) at energies well below the Planck scale and at finite values of the scale factor such that the entire evolution remains classical. A common claim has been that a non-singular bounce either leads to ghost or gradient instabilities or a cosmological singularity. In this letter, we examine cubic Galileon theories and present a procedure for explicitly constructing examples of a non-singular cosmological bounce without encountering any pathologies and maintaining a sub-luminal sound speed for co-moving curvature modes throughout the NEC violating phase. We also discuss the relation between our procedure and earlier work.

Metáforas: eufemismos y disfemismos en los titulares de prensa sobre el tema de la muerte en el periódico Q’hubo, un análisis crítico del discurso

Subjects: subject: Análisis crítico del discurso
subject: Análisis del discurso narrativo
subject: Tabu
subject: Feminismo y literatura

description: Esta investigación tuvo como propósito establecer, desde el Análisis Crítico del Discurso (ACD), las diversas formas en las que operan las figuras retóricas –metáforas especiales: eufemismos y disfemismos– en la construcción ideológica del tabú de la muerte en los titulares de prensa del periódico Q’hubo Cartagena, para identificar su tendencia de uso. Se utilizaron 50 titulares de noticias que datan entre 2008 a 2018, escogiendo solamente lunes, sábados y domingos por ser los días donde más se presentaban sucesos fatales. Para ello se analizó la estructura sintáctica de los titulares en sintagmas nominales, verbales y adjetivales; la función social de los mismos y las ideologías subyacentes en ellos. Los resultados mostraron que dichas figuras retóricas permiten abordar temas tabuizados. Además, se pudo develar que el discurso periodístico utilizado en el Q’hubo de Cartagena hace uso de expresiones cargadas de ideologías religiosas y simbólicas que existen asociadas a dicho tema. Ello sirvió para dar cuenta de la compleja relación que se entreteje entre discurso, sociedad e ideología, y que se evidencia en los imaginarios que se construyen en torno a temáticas inherentes al ser humano y, en general, a los seres vivos, como lo es la muerte.

description: A family of sets is said to be \emph{intersecting} if any two sets in the family have nonempty intersection. In 1973, Erdős raised the problem of determining the maximum possible size of a union of $r$ different intersecting families of $k$-element subsets of an $n$-element set, for each triple of integers $(n,k,r)$. We make progress on this problem, proving that for any fixed integer $r \geq 2$ and for any $k \leq (\tfrac{1}{2}-o(1))n$, if $X$ is an $n$-element set, and $\mathcal{F} = \mathcal{F}_1 \cup \mathcal{F}_2 \cup \ldots \cup \mathcal{F}_r$, where each $\mathcal{F}_i$ is an intersecting family of $k$-element subsets of $X$, then $|\mathcal{F}| \leq {n \choose k} - {n-r \choose k}$, with equality only if $\mathcal{F} = \{S \subset X:\ |S|=k,\ S \cap R \neq \emptyset\}$ for some $R \subset X$ with $|R|=r$. This is best possible up to the size of the $o(1)$ term, and improves a 1987 result of Frankl and Füredi, who obtained the same conclusion under the stronger hypothesis $k < (3-\sqrt{5})n/2$, in the case $r=2$. Our proof utilises an isoperimetric, influence-based method recently developed by Keller and the authors.

Assessment On Project Risk Management Practices In Railway Construction Projects: The Case Of Ethiopian Railways Corporation
Creators: name: Juhar, Aminu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The history of the railway sector in Ethiopia has been dominated by the story of Ethio-Djibouti Railway Company for more than a century. However recently Ethiopia is investing billions of dollars, which is highly indebting the country, to construct railway infrastructures throughout the country and their successful completion and operation is a must. To be successful, a project organization should be committed to address risk management proactively and consistently throughout the project. This study tries to assess and shade light on the current project risk management practices of railway construction projects undertaken by Ethiopian Railways Corporation.To address the research objective review of related literatures is made; questionnaires were prepared and distributed to selected respondents to collect necessary data. After collecting and analyzing data the study has identified that due to different factors the level of risk awareness in ERC is low. In addition it is pointed out by the study that the corporation is not giving proper emphasis for risk management practices indicated through not assigning adequate resources for the risk management activities, poor communication, lack of experience in risk management practices, no training and development programs, not structuring a well-organized specific department for managing risks and having no handy risk policy. The research further identified financial risks as a type of risk which is highly probable to occur and with a relatively high impact on project cost. Access to construction site and material risks are further recognized by the study as having relatively high impact on project time and quality respectively. Finally, based on the findings and conclusions made, the research ends by providing recommendations which will help to enhance the project risk management practices of ERC.

Tilings in graphons

Subjects: subject: Combinatorics (math.CO)

description: We introduce a counterpart to the notion of vertex disjoint tilings by copy of a fixed graph F to the setting of graphons. The case F=K_2 gives the notion of matchings in graphons. We give a transference statement that allows us to switch between the finite and limit notion, and derive several favorable properties, including the LP-duality counterpart to the classical relation between the fractional vertex covers and fractional matchings/tilings, and discuss connections with property testing. As an application of our theory, we determine the asymptotically almost sure F-tiling number of inhomogeneous random graphs \mathbb{G}(n,W). As another application, in an accompanying paper [Hladky, Hu, Piguet: Komlos's tiling theorem via graphon covers, preprint] we give a proof of a strengthening of a theorem of Komlos [Komlos: Tiling Turán Theorems, Combinatorica, 2000].
