description: We provide a numerical framework with which spatially and spectrally accurate representations of X-ray binary populations can be studied from hydrodynamical cosmological simulations. We construct average spectra accounting for a hot gas component and verify the emergence of observed scaling relations between galaxy wide X-ray luminosity ($L_{X}$) and stellar mass ($M_{\star}$) as well as star-formation rate (SFR). Using simulated galaxy halos extracted from the $(48\,h^{-1} \mathrm{cMpc})^3$ volume of the Magneticum Pathfinder cosmological simulations at $z = 0.07$ we generate mock spectra with the X-ray photon-simulator Phox. We extend the Phox code to account for the stellar component in the simulation and study the resulting contribution in composite galactic spectra. Average X-ray luminosity functions are perfectly reproduced up to the one-photon luminosity limit. Comparing our resulting $L_{X}-\mathrm{SFR}-M_{\star}$ relation for X-ray binaries with recent observations of field galaxies in the Virgo galaxy cluster we find significant overlap. Invoking a metallicity dependent model for high-mass X-ray binaries yields an anti-correlation between mass-weighted stellar metallicity and SFR normalized luminosity. The spatial distribution of high-mass X-ray binaries coincides with star-formation regions of simulated galaxies while low-mass X-ray binaries follow the stellar mass surface density. X-ray binary emission is the dominant contribution in the 2-10 keV band in the absence of an actively accreting central super-massive black hole with 50% contribution in the 0.5-2 keV band rivaling the hot gas component. Our modelling remains consistent with observations despite uncertainties connected to our approach. The predictive power and easily extendable framework hold great value for future investigations of galactic X-ray spectra.

description: Let $D$ be a diagram of an alternating knot with unknotting number one. The branched double cover of $S^3$ branched over $D$ is an L-space obtained by half integral surgery on a knot $K_D$. We denote the set of all such knots $K_D$ by $\mathcal D$. We characterize when $K_D\in \mathcal D$ is a torus knot, a satellite knot or a hyperbolic knot. In a different direction, we show that for a given $n>0$, there are only finitely many L-space knots in $\mathcal D$ with genus less than $n$.

description: Supersolid inflation is a class of inflationary theories that simultaneously breaks time and space reparameterization invariance during inflation, with distinctive features for the dynamics of cosmological fluctuations. We investigate concrete realizations of such a scenario, including non-minimal couplings between gravity and the fields driving inflation. We focus in particular on the dynamics of primordial gravitational waves and discuss how their properties depend on the pattern of symmetry breaking that we consider. Tensor modes can have a blue spectrum, and for the first time we build models in which the squeezed limit of primordial tensor bispectra can be parametrically enhanced with respect to standard single-field scenarios. At leading order in a perturbative expansion, the tensor-to-scalar ratio depends only on the parameter controlling the breaking of space-reparameterization. It is independent from the quantities controlling the breaking of time-reparameterization, and this represents a difference with respect to standard single-field inflationary models.

Assessment of the Challenges of Risk Management Implementation in ethio telecom, Telecom Expansion Program (TEP)
Creators: name: Kebede, Daniel
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The development of a stronger risk culture across the whole organization offers greater benefits. Such a risk culture would mean tackling a number of current challenges. Make everyone responsible for managing risks and for everyone to take accountability for doing so, so that the management of risk becomes an everyday, whole-company approach. If people are to be empowered to manage risks then the next challenge is to train and educate people within the organization so that they have the tools and the skills to manage risks that they face. This includes general risk management awareness training for everyone, with more specialized risk and opportunity management training for those who deal with specific types of risk, whether financial, security, project, safety, or other. The purpose of this study is to assess challenges of risk management implementation in Telecom Expansion Program of ethio telecom. The program's risk management implementation is assessed in line with the five risk management processes of; planning, identification, analysis, response and monitoring. Questionnaire was developed based on each risk management process and distributed to 40 respondents. The data obtained from the questionnaire was analyzed quantitatively using SPSS software and the data collected from interview were analyzed qualitatively. The quantitative data were presented using tables, graphs & charts and the qualitative data was used to support and elaborate the quantitative data. From the quantitative and qualitative data it was found that the program gives the utmost attention for risk management and included risk management in the program's plan. Risks arise at each stage of the program were managed throughout the program lifecycle. Risk analysis and monitoring was performed well in the program whereas risk identification is not performed exhaustively. The main challenges resulting from the study was: lack of risk expert to lead RM team, lack of practical experience, lack of risk knowledge and information and low level of awareness among stakeholders. Lack of risk management expert to lead RM is observed persistently in every stage of risk management. To overcome the challenges mentioned above and to enjoy the benefits of good risk management, the researcher suggested: ownership and accountability of risks must be created among stakeholders through allowing them to have a part on risk management process. The company must see other options to get a skilled manpower to handle its future risks. On the top of these, intensive risk management awareness creation training must be provided to everyone to enhance the risk management culture.

description: We study quasiconformal deformations and mixing properties of hyperbolic sets in the family of holomorphic correspondences z^r +c, where r >1 is rational. Julia sets in this family are projections of Julia sets of holomorphic maps on C^2, which are skew-products when r is integer, and solenoids when r is non-integer and c is close to zero. Every hyperbolic Julia set in C^2 moves holomorphically. The projection determines a branched holomorphic motion with local (and sometimes global) parameterisations of the plane Julia set by quasiconformal curves.

description: Cognitive remediation (CR) may alleviate cognitive difficulties in schizophrenia. This thesis: 1) examined the impact of drill-and-strategy CR on cognition, living skills and self-efficacy compared to computer game (CG) control; 2) explored the impact of intrinsic motivation on therapy outcomes; and 3) compared the lived experience of both groups. Overall, CR produced greater improvements in cognition, which was more likely when motivation increased over time. CR and CG both enhanced self-efficacy, yet neither improved living skills. Learning new skills and encountering challenge were unique processes in CR. These findings should be considered when developing and delivering CR therapies in future.

description: We report on the implementation of degenerate Raman sideband cooling of $^{40}$K atoms. The scheme incorporates a 3D optical lattice, which confines the atoms and drives the Raman transitions. The optical cooling cycle is closed by two optical pumping beams. The wavelength of the laser beams forming the lattice is close to the D$_2$ atomic transition, while the optical pumping is operated near the D$_1$ transition. With this cooling method, we achieve temperature of $\sim$$1μ$K of a cloud with $\sim$$10^7$ atoms. This corresponds to a phase space density of $\ge$$10^{-3}$. Moreover, the fermionic ensemble is spin polarized to conditions which are favorable for subsequent evaporative cooling. We study the dependence of the cooling scheme on several parameters, including the applied magnetic field, the detuning, duration, and intensity profile of the optical pumping beams. Adding this optical cooling stage to current Fermi gas experiments can improve the final conditions and increase the data rate.

description: Direct detection bounds are beginning to constrain a very simple model of weakly interacting dark matter---a Majorana fermion with a coupling to the $Z$ boson. In a particularly straightforward gauge-invariant realization, this coupling is introduced via a higher-dimensional operator. While attractive in its simplicity, this model generically induces a large $ρ$ parameter. An ultraviolet completion that avoids an overly large contribution to $ρ$ is the singlet-doublet model. We revisit this model, focusing on the Higgs blind spot region of parameter space where spin-independent interactions are absent. This model successfully reproduces dark matter with direct detection mediated by the $Z$ boson, but whose cosmology may depend on additional couplings and states. Future direct detection experiments should effectively probe a significant portion of this parameter space, aside from a small coannihilating region. As such, $Z$-mediated thermal dark matter as realized in the singlet-doublet model represents an interesting target for future searches.

Assessment Of The Effect Leadership Style And Culture On Project Performance- The Case Of High-Grade Ethiopian And Chinese Contractors In Ethiopia
Creators: name: Tebeje, Zinabu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The focus of previous researches done on the construction sector have been managerial and technical features of contraction projects. This study aims to explores and evaluate three fundamental issues: first, it aims to compare leadership styles adopted by Ethiopian and Chinese construction mangers; second, it examines the culture effect on leadership styles; and third, the non-parametric (Mann-Whitney) and parametric result (T-Test) for five-point Likert scale analysis has been computed and compared. Date was collected using structured questionnaire using random sampling technique for the Ethiopian contractors. For Chinese contractors who are registered in Ethiopia, the whole population were considered and all of them were requested to fill the questionnaire. Analysis using MWW showed that both Ethiopian and Chinese contractors are prone to use transformational and transactional leadership respectively. However, T-Test showed that both countries are prone to use transformation leadership. Culture exerts a little impact on leadership style, demonstrated by strong correlation only for power distance and transactional leadership style (Correlation=0.641**). Analysis of the effect of culture in leadership indicated that Ethiopia could be concluded to be a country of low power distance, high uncertainty avoidance, collective and feminine society. On the other hand, China is high power distance, high uncertainty avoidance and highly collective society. For the comparison between the non-parametric and parametric analysis, the non-parametric test has to be used as it showed some difference with the parametric result (T-Test). Pearson and Spearman showed the same result for correlation

description: We present simulations of cumulus convection over land with shortwave radiation computed by a Monte Carlo ray tracer coupled to the flow solver. Ray tracing delivers very realistic in-cloud heating rates and global horizontal irradiance fields. The necessary performance of the ray tracer has been enabled by the raw power of GPU computing and from techniques for accelerating data lookup and ray tracer convergence. We used a case study over a grassland in the Netherlands to compare simulations with a coupled ray tracer to those with a conventional two-stream solver, and to test ray tracer convergence. We demonstrate that the simulated cloud evolution is insensitive across a wide range of samples sizes in the ray tracer. Furthermore, simulations with a coupled ray tracer produce surface irradiance patterns that resemble observations and that strongly feed back to the evolution of clouds via locally enhanced surface heat fluxes.

description: This work provides a convenient and powerful means towards the engineering of Floquet bands via Bloch oscillations, by adding a tilted linear potential to periodically driven lattice systems. The added linear field not only restricts the spreading of a time-evolving wavepacket but also, depending on the ratio between the Bloch oscillation frequency and the modulation frequency of the periodic driving, dramatically modifies the band profile and topology. Specifically, we consider a driven Aubry-André-Harper model as a working example, in the presence of a linear field. Almost flat Floquet bands or Floquet bands with large Chern numbers due to the interplay between the periodic driving and Bloch oscillations can be obtained, with the band structure and topology extensively tunable by adjusting the ratio of two competing frequencies. To confirm our finding, we further execute the Thouless pumping of one and two interacting bosons in such a lattice system and establish its connection with the topological properties of single- and two-particle Floquet bands.

The films have been deposited on silicon substrate at different temperatures. Existence of the defects in the films have been verified using room temperature photo-luminescence measurements. Owing to nano crystalline nature of the films, super-magnetic ground states have been observed. A cross-over from super paramagnetic to super spin glass state has been observed as the grain density increases. Detailed magnetisation measurements along with AC susceptibility measurements have been used to determine the ground states in these AlN thin films.

description: El principal objeto de la siguiente monografía está en explicar la crítica que el filósofo greco francés, Cornelius Castoriadis, hace al neoliberalismo, el cual resulta contrario a la democracia. Igualmente, se muestra la idea de democracia como fundamento de la autonomía que reside en los ciudadanos tanto individual como colectivamente, y el recorrido por las tres esferas de la actividad humana: Oikos, Agora y Eclessia. Para su estudio se realizó la lectura de los trabajos del filósofo, sobre El avance de la insignificancia (1997), La institución de la sociedad y de la religión (en la obra Los dominios del hombre, 1998), La polis griega y la creación de la democracia (2005), la cual considera como el bien común de un grupo. Castoriadis crítica no solo al despliegue del sistema Capitalista, sino que también se esfuerza por discutir la doctrina marxista, sin perder el grado de rebeldía que lo caracteriza. En ese sentido, el filósofo plantea que “En ningún caso podemos considerar que la democracia es el espacio donde cada grupo social defiende sus intereses particulares”. Esta misma “no puede ser instrumental, una supuesta canalización de los intereses particulares en los que gana la mayoría como plantea el utilitarismo liberal". Las Significaciones Imaginarias Sociales, a las que se refiere el autor, se entienden como una organización del mundo, que establecen un conjunto de representaciones, las funciones de los miembros del grupo y el tipo de efectos predominantes. Dichas significaciones se reflejan en la crítica que Castoriadis hace al neoliberalismo y al capitalismo contemporáneo, el ansia de consumir y creer en una ilusión de la democracia en el contexto del capitalismo neoliberal.

description: In this work we study the production of two Higgs bosons at the two planned electron positron colliders with energies at the TeV domain, CLIC and ILC, within the context of Effective Field Theories (EFTs) to describe beyond the Standard Model Higgs Physics. We focus first on the case of the Higgs Effective Field Theory (HEFT) and next we compare with the case of the Standard Model Effective Field Theory (SMEFT). The predictions for double Higgs production in both EFTs are first presented for the most relevant subprocess participating in the total process of our interest, $e^+e^- \to HH ν\bar ν$, which is the scattering of two gauge bosons, $WW \to HH$, also called $WW$ fusion. The predictions for the cross section $ σ(W_X W_Y\to HH)$ as a function of the subprocess energy are analyzed in full detail for the two EFTs, for all the polarization channels with longitudinal and transverse modes $XY=LL, TT,LT,TL$, and for the most relevant effective operators in both cases. We will demonstrate that in the HEFT case, the total cross section can be fully understood in terms of the $LL$ contribution and this in turn is dominated at these TeV energies mainly by two HEFT coefficients. By doing the matching between the two EFTs at the level of the scattering amplitude for the subprocess, we will be able to find the correspondence of the leading coefficients in the HEFT and the SMEFT. In the final part of this work we will then explore the sensitivity to these two most relevant HEFT coefficients, at CLIC (3 TeV, 5 ab$^{-1}$) and ILC (1 TeV, 8 ab$^{-1}$). We will then conclude on the accessible region of these two parameters by studying the predicted rates at these two $e^+e^-$ colliders for the final state $b \bar b b \bar b ν\bar ν$ leading to characteristic signals with 4 bottom jets and missing energy.

description: Increasing the number of closely-packed air bubbles immersed in water changes the frequency of the Minnaert resonance. The collective interactions between bubbles in a small ensemble are primarily in the same phase, causing them to radiate a spherically-symmetric field that peaks at a frequency lower than the Minnaert resonance for a single bubble. In contrast, large periodic arrays include bubbles that are further apart than half the wavelength, so that collective resonances have bubbles oscillating in opposite phases, ultimately creating a fundamental resonance at a frequency higher than the single-bubble Minnaert resonance. This work investigates the transition in resonance behavior using a modal analysis of a mass-spring system and a boundary element method. We significantly reduce the computational complexity of the full-wave solver to a linear dependence on the number of bubbles in a rectangular array. The simulated acoustic fields confirm the initial downshift in resonance frequency and the strong influence of collective resonances when the array has hundreds of bubbles covering more than half the wavelength. These results are essential in understanding the low-frequency resonance characteristics of bubble ensembles, which have important applications in diverse fields such as underwater acoustics, quantum physics, and metamaterial design.

description: The aim of this research was to strengthen the medico-legal evidence base for analysing and interpreting the skeletal trauma that results from fatal falls. Using the full-body post-mortem computed tomography scans of 298 individuals who were known to have died from low free falls, falls involving stairs and high free falls, fracture patterns and morphologies were investigated. Results indicate there are a number of significant fracture patterns and morphologies characteristic of each of these fall types. Findings will allow forensic anthropologists to better interpret the mechanism of trauma in cases of skeletal remains where the circumstances of death are unknown.

Year: 2017

description: The purpose of this research is to assess the traditional status quo cost control system practiced in DAC PLC, evaluate how effectively the system measure performance, and predict the future project health based on the past performance. Identify gaps and limitations in the system, demonstrate EVM as an alternative cost control approach using a real time project data, show the effectiveness of EVM approach in terms measuring the project cost and schedule variances, efficiencies as well as predicating future performance trends along with the main parameters involves in the calculation. Consequently, recommend adoption of the Earned Value Management system to the construction firm so as to reap its comparative advantage over the traditional approach in minimizing project cost overrun and schedule delay. The research used quantitative cost and schedule related data which put into an Excel template prepared for EVA calculations. The project variance, efficiency and forecast indicators generated by Excel tool, depicted in graphs, tables and dashboard and the interpretation of results provided. In the whole process of EVA determination of performance indicators as well as interpretations of results, the effectiveness EVM approach against the traditional method is clearly compared. The findings showed that EVM approach has come more effective cost monitoring and control tool compared to the traditional system in order to identify potential schedule slippages and areas of budget overruns. In traditional project cost control system one determines the budget and measures the cost against that budget as project goes on while the EVM approach differs from conventional performance measurement practices by combining a project's cost and schedule parameters into a common framework, i.e. the measurement of the budgeted value of the work actually carried out, and its comparison with the budgeted value of the work that should have been carried out and what it actually costs. The study demonstrated the earned value technique, as it provides objective, realistic assessment of project status information for management using parametric generated with combination of (Earned Value), (planned Value), (Actual Cost), (Budget At Completion) and (Original Duration). So, t is an important component of any effective project management system, with its early warning status approach, resulting in significant improvements to its performance and contributing to a company's competitiveness and overall profitability. By adapting Earned Value concept DAC and similar construction projects will benefit the fast and accurate project performance indicators using the mathematical approach provided by Earned Value Management. Therefore, this easier and better accurate EVM method enables the project make periodic monitoring of the project health and to take prompt actions on performance discrepancies before problems grow to unrecoverable level or need major scope changes.

Subjects: subject: 110310 Intensive Care
subject: FOS: Clinical medicine

description: The intensive care unit provides continuous surveillance and highly specialized care for the sickest hospitalized patients. It is a high cost service and an assessment of its performance is necessary to optimize quality of care while minimizing costs. This research has developed a set of novel prognostic systems to predict hospital mortality in critically ill adults in Australasia for the purpose of monitoring and evaluating intensive care services. The Australian and New Zealand Risk of Death model contained in this thesis has significantly improved casemix adjustment and facilitated more accurate benchmarking of intensive care performance throughout Australia and New Zealand.

Quantum Key Distribution with Mismatched Measurements over Arbitrary Channels
Creators: name: Krawec, Walter O.
Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper, we derive key-rate expressions for different quantum key distribution protocols. Our key-rate equations utilize multiple channel statistics, including those gathered from mismatched measurement bases - i.e., when Alice and Bob choose incompatible bases. In particular, we will consider an Extended B92 and a two-way semi-quantum protocol. For both these protocols, we demonstrate that their tolerance to noise is higher than previously thought - in fact, we will show the semi-quantum protocol can actually tolerate the same noise level as the fully quantum BB84 protocol. Along the way, we will also consider an optimal QKD protocol for various quantum channels. Finally, all the key-rate expressions which we derive in this paper are applicable to any arbitrary, not necessarily symmetric, quantum channel.
Dynamical evolution in the D1D5 CFT

Subjects: subject: High Energy Physics - Theory (hep-th)

description: It is interesting to ask: how does the radial space direction emerge from the CFT in gauge-gravity duality? In this context we resolve a long-standing puzzle with the gravity duals of two classes of states in the D1D5 CFT. For each class the CFT states are in the untwisted sector, suggesting that the energy gap should be $1/R_y$ where $R_y$ is the radius of the circle on which the D1D5 CFT is compactified. For one class of states, the gravity dual indeed has exactly this gap, while for the other class, the gravity dual has a very deep throat, leading to an energy gap much smaller than $1/R_y$. We resolve this puzzle by showing that for the latter class of states, perturbing the CFT off its free point leads to the formation of a band structure in the CFT. We also explain why such a band structure does not arise for the first class of states. Thus for the case where a deep throat emerges in the gravity description, the dynamics of falling down this throat is described in the CFT as a sequential `hopping' between states all of which have the same energy at the free point; this hopping amplitude converts an integer spaced spectrum into a closely spaced band of energy levels.

description: Memory impairment is commonly experienced following stroke yet remains a high unmet need within the community. Two approaches have been used to rehabilitate memory: group compensation and computerised restoration. Despite decades of research into each respective approach, there is no clear consensus on how to best rehabilitate memory. This thesis sought to address this gap by exploring and contrasting restorative and compensatory approaches to memory rehabilitation following stroke. Using a mixed methodology approach, this study provides preliminary evidence that group compensation may be more more effective and enjoyable than computerised restoration in remediating everyday memory failures.
