Creators: name: Hamelmal, Tigist
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The purpose of this research is to examine the extent how cross-cultural diversity affects organizational effectiveness in selected international organizations in Addis Ababa. This research was aimed to achieve the following objectives; to assess, explain and identify how power distance, individualism/collectivism, masculinity/femininity uncertainty avoidance time orientation affect the organizational effectiveness. This research adopted explanatory research design to explain the relationship between variables. Quantitative method of research approach was also used to test the relationship between the dependent variables and independent variables. The target populations of this research were comprised of 462 professional employees from the two organizations 352 and 110 respectively. The researcher used 15% sale size from each organization and 70 questionnaires were distributed; 68 were returned. The questionnaire was a self-prepared questionnaire measured on Likert scale used to collect data from respondents. The questionnaire reliability was tested by using Cronbach's Alpha test. The data obtained was analyzed by using statistical Package for Science. Descriptive and inferential statistics method was used to analyze the collected data. The correlation analysis evidenced that cultural diversity influences organizational effectiveness. The beta coefficient results also showed that culture has an influence in bringing variation in organizational effectiveness

description: A major open problem in the theory of twisted commutative algebras (tca's) is proving noetherianity of finitely generated tca's. For bounded tca's this is easy, in the unbounded case, noetherianity is only known for Sym(Sym^2(C^\infty)) and Sym(\wedge^2(C^\infty)). In this paper, we establish noetherianity for the skew-commutative versions of these two algebras, namely \wedge(Sym^2(C^\infty)) and \wedge(\wedge^2(C^\infty)). The result depends on work of Serganova on the representation theory of the infinite periplectic Lie superalgebra, and has found application in the work of Miller-Wilson on "secondary representation stability" in the cohomology of configuration spaces.

description: We develop a formally exact technique for obtaining steady-state distributions of non-interacting active Brownian particles in a variety of systems. Our technique draws on results from the theory of two-way diffusion equations to solve the steady-state Smoluchowski equation for the 1-particle distribution function. The methods are employed to study in detail three scenarios: 1) confinement in a channel, 2) a constant flux steady state, and 3) sedimentation in a uniform external field. In each scenario, known behaviors are reproduced and precisely quantified, and new results are presented. In particular, in the constant flux state we derive an effective diffusivity which interpolates between the ballistic behavior of particle trajectories at short distances and their diffusive behavior at large distances. We also calculate the sedimentation profile of active Brownian particles near a wall, which complements earlier studies on the part far from the wall. Our techniques easily generalize to other active models, including systems whose activity is modeled in terms of Gaussian colored noise.

description: Using conformal field theory and localization tecniques we study the propagation of waves in gravity backgrounds described by Schrödinger like equations with Fuchsian singularities. Exact formulae for the connection matrices relating the asymptotic behaviour of the wave functions near the singularities are obtained in terms of braiding and fusion rules of the CFT. The results are applied to the study of quasi normal modes, absorption cross sections, amplification factors, echoes and tidal responses of black holes (BH) and exotic compact objects (ECO) in four and five dimensions. In particular, we propose a definition of dynamical Love numbers in gravity.

description: This paper examines communities’ accessibility to critical facilities such as hospitals, emergency medical services, and emergency shelters when facing flooding. We use travel speed reduction to account for flood-induced partial road failure. A modified betweenness centrality metric is also introduced to calculate the criticality of roads for connecting communities to critical facilities. The proposed model and metric are applied to the Delaware road network under 100-year floods. This model highlights the severe critical facility access loss risk due to flood isolation of facilities. The mapped post-flooding accessibility suggests a significant travel time increase to critical facilities and reveals disparities among communities, especially for vulnerable groups such as long-term care facility residents. We also identified critical roads that are vital for post-flooding access to critical facilities. The results of this research can help inform targeted infrastructure investment decisions and hazard mitigation strategies that contribute to equitable community resilience enhancement.

description: We compute a spectrum of parametric X-ray radiation (PXR) inside a crystal from a bunch of electrons, which is periodically modulated in density. We consider that the bunch of electrons is exiting from a XFEL channel. We demonstrate that in the case of a resonance between the frequency of parametric X-ray radiation and a frequency of modulation of an electron bunch the sequence of strong quasi-monochromatic X-ray pulses is formed -- superradiant parametric X-ray emission (SPXE) with frequencies multiples of the modulation frequency. The number of photons in the impulse of SPXE in the case of an extremely asymmetric diffraction is comparable with the photon number in the impulse of a XFEL. Moreover the SPXE is directed under the large angle to the electron velocity and every harmonic in the spectrum is emitted under its own angle.

description: The quantum Cramér-Rao bound (QCRB) sets a fundamental limit for the measurement of classical signals with detectors operating in the quantum regime. Using linear-response theory and the Heisenberg uncertainty relation, we derive a general condition for achieving such a fundamental limit. When applied to classical displacement measurements with a test mass, this condition leads to an explicit connection between the QCRB and the Standard Quantum Limit which arises from a tradeoff between the measurement imprecision and quantum backaction; the QCRB can be viewed as an outcome of a quantum non-demolition measurement with the backaction evaded. Additionally, we show that the test mass is more a resource for improving measurement sensitivity than a victim of the quantum backaction, which suggests a new approach to enhancing the sensitivity of a broad class of sensors. We illustrate these points with laser interferometric gravitational wave detectors.

description: The advent of next generation radio telescope facilities, such as the Square Kilometer Array (SKA), will usher in an era where a Pulsar Timing Array (PTA) based search for gravitational waves (GWs) will be able to use hundreds of well timed millisecond pulsars rather than the few dozens in existing PTAs. A realistic assessment of the performance of such an extremely large PTA must take into account the data analysis challenge posed by an exponential increase in the parameter space volume due to the large number of so-called pulsar phase parameters. We address this problem and present such an assessment for isolated supermassive black hole binary (SMBHB) searches using a SKA era PTA containing $10^3$ pulsars. We find that an all-sky search will be able to confidently detect non-evolving sources with redshifted chirp mass of $10^{10}$ $M_\odot$ out to a redshift of about $28$ (corresponding to a rest-frame chirp mass of $3.4\times 10^{8}$ $M_\odot$). We discuss the important implications that the large distance reach of a SKA era PTA has on GW observations from optically identified SMBHB candidates. If no SMBHB detections occur, a highly unlikely scenario in the light of our results, the sky-averaged upper limit on strain amplitude will be improved by about three orders of magnitude over existing limits.

title: The Application of a New Mass Spectrometry Technique Using Non-Invasive Biological samples for Conservation and Ecology Studies
Creators: name: Koch, Natalie
Publisher: name: University of Liverpool Repository
Year: 2023

description: Effective conservation strategies are required to increase biodiversity. More information about a species increases the chances of choosing policies that enhance survival. Many historical population monitoring methods, such as live trapping, were invasive or difficult to implement for particular species or locations. This has led to the development of molecular analysis of non-invasive samples, including faeces. Faecal samples are easy to collect and store; they are a potentially rich source of information and do not require direct observation of the animal. Faecal samples can be used to obtain genetic information, but techniques are labour-intensive and time-consuming, and the abundance of hormones in faecal samples degrades with time. The potential of a new ambient mass spectrometry technique to analyse faecal samples was investigated in this study. Rapid Evaporative Ionisation Mass spectrometry (REIMS) was developed for medicine to distinguish between cancerous and healthy tissue. It was used in food security to determine if the origin of a food source is as advertised. We have shown that REIMS can discriminate different species of rodents. This study aimed to determine the scope of REIMS to differentiate faecal samples of laboratory animals by analysing the sex, maturity and strain of different lab mice. The discrimination ability of REIMS was also explored in captive zoo animals to determine whether REIMS could be used to detect pregnancy. The practicality of REIMS in field studies was tested, and the ability to use REIMS as a method for population monitoring was determined by establishing the species distribution of rodents in multiple field sites. The power of REIMS to distinguish between more subtle differences; sex, maturity, strain and pregnancy; was limited compared to species. The composition of faecal samples did change with storage time, but REIMS could still distinguish between species of samples that had been in the freezer for over two years. REIMS established the species distribution of three rodent species across four field sites. Therefore, REIMS can be used as an additional non-invasive method to aid conservation and ecology studies.

description: Recently, a type of Hall effect due to an unusual layer-locked Berry curvature called the layer Hall effect (LHE) has been reported in the even-layered two-dimensional antiferromagnetic (AFM) MnBi2Te4 [A. Gao et.al, Nature 595, 521 (2021)]. In this work, we report that the quantization of LHE, which we call the quantum anomalous layer Hall effect (QALHE), can be realized in MnBi2Te4. The QALHE originates from kicking a layer-locked Berry-curvature monopole out of the Fermi sea by a vertielectric cal field. Remarkably, we demonstrate that the electric-field reversal can switch the sign of the quantized Hall conductance of QALHE in the even-layered AFM phase. The QALHE can also be realized in the ferromagnetic phase. These results provide a promising way toward the electric engineering of the Berry curvature monopoles and quantized-layered transport in topological magnets.

description: It is known that malware can leak data from isolated, air-gapped computers to nearby smartphones using ultrasonic waves. However, this covert channel requires access to the smartphone's microphone, which is highly protected in Android OS and iOS, and might be non-accessible, disabled, or blocked. In this paper we present `GAIROSCOPE,' an ultrasonic covert channel that doesn't require a microphone on the receiving side. Our malware generates ultrasonic tones in the resonance frequencies of the MEMS gyroscope. These inaudible frequencies produce tiny mechanical oscillations within the smartphone's gyroscope, which can be demodulated into binary information. Notably, the gyroscope in smartphones is considered to be a 'safe' sensor that can be used legitimately from mobile apps and javascript. We introduce the adversarial attack model and present related work. We provide the relevant technical background and show the design and implementation of GAIROSCOPE. We present the evaluation results and discuss a set of countermeasures to this threat. Our experiments show that attackers can exfiltrate sensitive information from air-gapped computers to smartphones located a few meters away via Speakers-to-Gyroscope covert channel.

description: An isoscalar $pn$ pair is expected to emerge in nuclei that have similar proton and neutron numbers and it may be a candidate for a deuteron ``cluster.'' There is, however, no experimental evidence for it. The purpose of this paper is to construct a new reaction model for the ($p,pd$) reaction including the deuteron breakup in the elementary process and the deuteron reformation by the final-state interactions (FSIs). How these processes contribute to the observables of the reaction is investigated. The distorted wave impulse approximation is extended in twofold. The elementary processes of the ($p,pd$), i.e., the $p$-$d$ elastic scattering and $d(p,p)pn$ reaction, are described with an impulse picture employing a nucleon-nucleon effective interaction. The three-body scattering waves in the final state of the ($p,pd$) reaction are calculated with the continuum-discretized coupled-channels method. The triple differential cross section (TDX) of the ($p,pd$) reaction is calculated with the new model. The elementary processes are described reasonably well with the present model. As for the ($p,pd$) reaction, the deuteron reformation can either increase or decrease the TDX height depending on the interference between the elastic and breakup channel of deuteron, while the \textit{back-coupling} effect always decreases it. It is shown that the deuteron reformation significantly changes the TDX of the ($p,pd$) reaction through the interference. It is important to include this process to quantitatively discuss the ($p,pd$) cross sections in view of the deuteron formation in nuclei. For more quantitative discussion regarding the experimental data, further improvement will be necessary.

description: We study the viscous dissipation in pipe flows in long channels with porous or semipermeable walls, taking into account both the dissipation in the bulk of the channel and in the pores. We give simple closed form expressions for the dissipation in terms of the axially varying flow rate $Q(x)$ and the pressure $p(x)$, generalizing the well known expression $\dot W=Q\,Δp$ for the case of impenetrable walls with constant $Q$ and a pressure difference $Δp$ between the ends of the pipe. When the pressure $p_0$ outside the pipe is constant, the result is the straightforward generalization $\dot W=Δ\left[(p-p_0) \,Q\right]$. Finally, applications to osmotic flows are considered.

description: The construction industry has been seen as one of the hazardous industries. This is because the industry has a poor health and safety performance record compared to other industries all over the world. Labor law in every nation provides that it is the duty of an employer to ensure that every worker employed works under satisfactory, safe and healthy conditions. Health and safety at construction sites deals with both physical and psychological well being of workers on construction sites and other persons whose health is likely to be adversely affected by construction activities. The major objectiveof this research is to present findings of health and safety management practices in building construction recently constructed in Addis Ababa, Ethiopia under YOTEK construction plc. 60 of employees were selected for the study for which a questionnaire was distributed and additionally documented sources were looked for more accurate data including site observation. Consequently, the study result revealed that relatively through time the company is developing better Health and safety (HS) practice but there are also limitations such as lack of management motivation and commitment in implementation and workers'carelessness

Coming on the heels of our previous work about $T_{cc}$ and $T_{bb}$, we present a study on the bound states and the resonant states of its companions $QQ\bar{q}\bar{s}$ ($Q=c,b; q=u, s$) tetraquarks with strange flavor in the chiral quark model. Two pictures, one with meson-meson picture, another with diquark-antidiquark picture and their couplings are considered in our calculations. Isospin violation is neglected herein. Our numerical analysis indicates that only the state $bb\bar{u}\bar{s}$ with $\frac{1}{2}(1^+)$ is bound, with the binding energy 3.5 MeV. Besides, we also find some resonant states for the double-heavy strange tetraquarks with the real scaling method.

To study this subject matter, Ethiopian Insurance Corporation labor union which has 899 members was selected. The study used descriptive research design and employed mixed research approach, to investigate the extent to which the labor union participates and allows its own members to take part in labor affairs to maintain good employment relation in the corporation. Due to the time and budget constraint, dispersed geographical location and similarity of work categories, data was collected from all offices that are located in Addis Ababa, where there are 511 union members. From this population size 224 union members were selected by using convenience sampling and 4 union leaders and 4 administrative managers were purposively selected by using purposive sampling, who were considered to be major informants. The sampled union members were asked to complete a self-administered questionnaire with 39 likert scale questions categorized in four parts. To check the internal consistency and reliability of the questions, pilot testing was conducted and Cronobach's Alpha of 0 .919 was acquired. The final response rate was 87% (N=190). The respondents' responses were analyzed using descriptive statistics through SPSS. The results are presented in the form of figures, charts and tables using mean and percentages. The findings revealed that the role of the labor union in ensuring the benefits of the union, in maintaining peaceful employment relation and in collective bargaining is good, whereas the overall role of labor union in promoting industrial democracy among union members and in the corporation is low. However, the labor union needs to work on creating ways to participate in strategic issues of the corporation, succession plan and employee promotion. And, most importantly it needs to work on finding ways to reach out all union members, so that they can participate in labor affairs and get up-to-date information about changes in the corporation
Merging binary black holes, their spins & formation: What do we know so far from gravitational waves?

description: Population studies of gravitational-wave events can help us probe the lives of compact binaries and the environments in which they form (e.g. field or clusters). Recent work has painted conflicting portraits of the distribution of black hole spins in merging binaries leading to different conclusions about their formation pathways. In this talk, I describe the emerging picture of black hole spin using observations from LIGO-Virgo–KAGRA with current spin models and explorations of various subpopulations. We find no clear evidence for a subpopulation of non-spinning black holes nor clear evidence for binaries with extreme misalignments. However, all three scenarios are consistent with the data. We also find that, at most, 89% of binaries are dynamically assembled. I will also discuss aspects of model misspecification and implications for future population studies.

description: La consideraciones fines que se presentan a continuación se ocuparán de algunos temas inquietantes en la confrontación con Nietzsche, el primero de ellos hará referencia al problema de la justicia, en otros términos, al choque inexorable entre las reivindicaciones sociales de algunos sectores por daños recibidos en el pasado, frente a la redención del mismo llevada a cabo por el superhombre con la ayuda de su capacidad de olvido. En el segundo tema abordaremos precisamente esa capacidad de olvido, frente a ésta nos preguntaremos si para el superhombre no seria necesaria una cuota de memoria que le permita no recaer en los modelos axiológicos anteriores. Encontrará también un espacio en la presente conclusión el rescate de la figura nietzscheana, nos enfrentaremos con esa plétora de ideas que tergiversaron y vulgarizaron al pensador Nietzsche. Para terminar, presentaremos una reflexión personal que logra rescatar aquello apreciado y querido en el superhombre, dejando de lado los elementos alarmantes que podrían desprenderse de esta figura.

description: Node classification using Graph Neural Networks (GNNs) has been widely applied in various real-world scenarios. However, in recent years, compelling evidence emerges that the performance of GNN-based node classification may deteriorate substantially by topological perturbation, such as random connections or adversarial attacks. Various solutions, such as topological denoising methods and mechanism design methods, have been proposed to develop robust GNN-based node classifiers but none of these works can fully address the problems related to topological perturbations. Recently, the Bayesian label transition model is proposed to tackle this issue but its slow convergence may lead to inferior performance. In this work, we propose a new label inference model, namely LInDT, which integrates both Bayesian label transition and topology-based label propagation for improving the robustness of GNNs against topological perturbations. LInDT is superior to existing label transition methods as it improves the label prediction of uncertain nodes by utilizing neighborhood-based label propagation leading to better convergence of label inference. Besides, LIndT adopts asymmetric Dirichlet distribution as a prior, which also helps it to improve label inference. Extensive experiments on five graph datasets demonstrate the superiority of LInDT for GNN-based node classification under three scenarios of topological perturbations.

description: I discuss the possible effects of a finite density of localised near-zero Dirac modes in the chiral limit of gauge theories with $N_f$ degenerate fermions. I focus in particular on the fate of the massless quasi-particle excitations predicted by the finite-temperature version of Goldstone's theorem, for which I provide an alternative and generalised proof based on a Euclidean ${\rm SU}(N_f)_A$ Ward-Takahashi identity. I show that localised near-zero modes can lead to a divergent pseudoscalar-pseudoscalar correlator that modifies this identity in the chiral limit. As a consequence, massless quasi-particle excitations can disappear from the spectrum of the theory in spite of a non-zero chiral condensate. Three different scenarios are possible, depending on the detailed behaviour in the chiral limit of the ratio of the mobility edge and the fermion mass, which I prove to be a renormalisation-group invariant quantity.

description: This paper proposes a new neural network architecture by introducing an additional dimension called height beyond width and depth. Neural network architectures with height, width, and depth as hyper-parameters are called three-dimensional architectures. It is shown that neural networks with three-dimensional architectures are significantly more expressive than the ones with two-dimensional architectures (those with only width and depth as hyper-parameters), e.g., standard fully connected networks. The new network architecture is constructed recursively via a nested structure, and hence we call a network with the new architecture nested network (NestNet). A NestNet of height $s$ is built with each hidden neuron activated by a NestNet of height $\le s-1$. When $s=1$, a NestNet degenerates to a standard network with a two-dimensional architecture. It is proved by construction that height-$s$ ReLU NestNets with $\mathcal{O}(n)$ parameters can approximate $1$-Lipschitz continuous functions on $[0,1]^d$ with an error $\mathcal{O}(n^{-(s+1)/d})$, while the optimal approximation error of standard ReLU networks with $\mathcal{O}(n)$ parameters is $\mathcal{O}(n^{-2/d})$. Furthermore, such a result is extended to generic continuous functions on $[0,1]^d$ with the approximation error characterized by the modulus of continuity. Finally, we use numerical experimentation to show the advantages of the super-approximation power of ReLU NestNets.

description: Weak measurements done on a subsystem of a bipartite system having both classical and nonClassical correlations between its components can potentially reveal information about the other subsystem with minimal disturbance to the overall state. We use weak quantum discord and the fidelity between the initial bipartite state and the state after measurement to construct a cost function that accounts for both the amount of information revealed about the other system as well as the disturbance to the overall state. We investigate the behaviour of the cost function for families of two qubit states and show that there is an optimal choice that can be made for the strength of the weak measurement.
