description: The apparent shape of galaxy clustering depends on the adopted cosmology used to convert observed redshift to comoving distance, the $r(z)$ relation, as it changes the line elements along and across the line of sight differently. The Alcock-Paczyński (AP) test exploits this property to constrain the expansion history of the universe. We present an extensive review of past studies on the AP test. We adopt an extended AP test method introduced by Park et al. (2019), which uses the full shape of redshift-space two-point correlation function (CF) as the standard shape, and apply it to the SDSS DR7, BOSS, and eBOSS LRG samples covering the redshift range up to $z=0.8$.We calibrate the test against the nonlinear cosmology-dependent systematic evolution of the CF shape using the Multiverse simulations. We focus on examining whether or not the flat $Λ$CDM `concordance' model is consistent with observation. We constrain the flat $w$CDM model to have $w=-0.892_{-0.050}^{+0.045}$ and $Ω_m=0.282_{-0.023}^{+0.024}$ from our AP test alone, which is significantly tighter than the constraints from the BAO or SNe I$a$ methods by a factor of 3 - 6. When the AP test result is combined with the recent BAO and SNe I$a$ results, we obtain $w=-0.903_{-0.023}^{+0.023}$ and $Ω_m=0.285_{-0.009}^{+0.014}$. This puts a strong tension with the flat $Λ$CDM model with $w=-1$ at $4.2σ$ level. Consistency with $w=-1$ is obtained only when the Planck CMB observation is combined. It remains to see if this tension between observations of galaxy distribution at low redshifts and CMB anisotropy at the decoupling epoch becomes greater in the future studies and leads us to a new paradigm of cosmology.

description: Within the framework of Boltzmann equation, we present a $\mathbf{k\cdot p}$ theory based study for the low-field mobilities of InSb nanowires (InSb NWs) with relatively large cross sectional sizes (with diameters up to 51.8 nm). For such type of large size nanowires, the intersubband electron-phonon scattering is of crucial importance to affect the scattering rate and then the mobility. In our simulation, the lowest 15 electron subbands and 50 transverse modes of phonons are carefully accounted for. We find that, up to the 51.84 nm diameter, the mobility monotonously increases with the diameter, not yet showing any saturated behavior. We also find that, while the bulk InSb mobility is considerably higher than the bulk Si, the small size (e.g. $\sim 3$ nm diameter) nanowires from both materials have similar magnitude of mobilities. This implies, importantly, that the mobility of the InSb NWs would decrease faster than the SiNWs as we reduce the cross sectional size of the nanowires.

description: Collimated outflows (jets) appear to be a ubiquitous phenomenon associated with the accretion of material onto a compact object. Despite this ubiquity, many fundamental physics aspects of jets are still poorly understood and constrained. These include the mechanism of launching and accelerating jets, the connection between these processes and the nature of the accretion flow, and the role of magnetic fields; the physics responsible for the collimation of jets over tens of thousands to even millions of gravitational radii of the central accreting object; the matter content of jets; the location of the region(s) accelerating particles to TeV (possibly even PeV and EeV) energies (as evidenced by gamma-ray emission observed from many jet sources) and the physical processes responsible for this particle acceleration; the radiative processes giving rise to the observed multi-wavelength emission; and the topology of magnetic fields and their role in the jet collimation and particle acceleration processes. This chapter reviews the main knowns and unknowns in our current understanding of relativistic jets, in the context of the main model ingredients for Galactic and extragalactic jet sources. It discusses aspects specific to active Galactic nuclei (especially blazars) and microquasars, and then presents a comparative discussion of similarities and differences between them.

description: In this work we first briefly review some of the mutual friction effects on vortex lines and rings that were obtained in the context of the truncated Gross-Pitaevskii equation in references Krstulovic \& Brachet [Phys.~Rev.~E \textbf{83}(6), 066311 and Phys.~Rev.~B \textbf{83}132506 (2011)], with particular attention to the anomalous slowdown of rings produced by thermally excited Kelvin waves. We then study the effect of mutual friction on the relaxation and fluctuations of Kelvin waves on straight vortex lines by comparing the results of full $3D$ direct simulations of the truncated Gross-Pitaevskii equation with a simple stochastic Local-Induction-Approximation model with mutual friction and thermal noise included. This new model allows us to determine the mutual friction coefficient $α$ and $α'$ for the truncated Gross-Pitaevskii equation.

description: Electromagnetically induced transparency (EIT) in three-level systems uses a strong control laser on one transition to modify the absorption of a weak probe laser on a second transition. The control laser creates dressed states whose decay pathways show interference. We study the role of dressed-state interference in causing EIT in the three types of three-level systems -- lambda ($Λ$), ladder ($Ξ$), and vee (V). In order to get realistic values for the linewidths of the energy levels involved, we consider appropriate hyperfine levels of $^{87}$Rb. For such realistic systems, we find that dressed-state interference causes probe absorption---given by the imaginary part of the susceptibility---to go to zero in a $Λ$ system, but plays a negligible role in $Ξ$ and V systems.

Experimental Investigation on Performance Characteristics and Efficiency of Electric Injera Baking Pans "(Mitad)"
Creators: name: Tafere, Awash
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: Enjera baking is the most energy intensive activity in Ethiopia; and preparation of enjera is rather a long process relative to other Ethiopian food. The aim of this thesis work is to investigate the performance characteristics and efficiency of the electric baking pan ("mitad") experimentally and to prove the efficiency of improved "mitad" is best. Experimentation and processing of data were performed to study the energy consumption cost and ways to increase the performance of the baking pan. Thermo-physical properties were determined quasi experimentally before, during, and after baking processes of the product ("Enjera"). Initial heating up and cyclic enjera baking time with its power consumption and heat loss analysis of the system were presented for performance comparison of the baking pans. Experiments were conducted to measure temperature profile during initial heating up and cyclic baking of the pans. Maximum energy losses are occurred at the bottom of conventional and improved baking pans with the efficiency of 52% and 75% respectively. Even though the efficiency of improved electric "mitad" was higher than the conventional one, still there was high energy loss due to poor insulation material. Performance improvement options of each baking pans can be made by increasing the number of cycles and density of the batter. This alternative can be increase the efficiency by 5-10% of the baking pans. Economic result illustrates that improved baking pan has higher initial capital investment than the conventional one; but they have lower operating costs. Then overall present worth of improved baking pan has lower cost than conventional baking pan. Finally, based on the points outlined above, improved electric "mitad" have an advantage over conventional electric "mitad" and our recommendation is to install improved baking pans in the kitchens of the Ethiopian house hold.

description: Solar flares and coronal mass ejections (CMEs) are thought to be the most powerful events on the Sun. They can release energy as high as 10^32 erg in tens of minutes,and could produce solar energetic particles (SEPs) in the interplanetary space. We explore global energy budgets of solar major eruptions on 6 September 2017, including the energy partition of a powerful solar flare, the energy budget of the accompanied CME and SEPs. In the wavelength range shortward of 222 nm, a major contribution of the flare radiated energy is in the soft X-ray (SXR) 0.1-7 nm domain. The flare energy radiated at wavelengths of Ly-alpha and middle ultraviolet is larger than that radiated in the extreme ultraviolet wavelength, but it is much less than that radiated in the SXR waveband. The total flare radiated energy could be comparable to the thermal and nonthermal energies. The energies carried by the major flare and its accompanied CME are roughly equal, and they are both powered by the magnetic free energy in the AR NOAA 12673. Moreover, the CME is efficient in accelerating SEPs, and that the prompt component (whether it comes from the solar flare or the CME) contributes only a negligible fraction.

description: The deep learning technique has been applied for the first time to investigate the possibility of centrality determination in terms of the number of participants ($N_{\mathrm{part}}$) in high-energy heavy-ion collisions. For this purpose, supervised learning using both deep neural network (DNN) and convolutional neural network (CNN) is performed with labeled data obtained by modeling relativistic heavy-ion collisions utilizing A Multi-phase Transport Model (AMPT). Event-by-event distributions of pseudorapidity and azimuthal angle of charged hadrons weighted by their transverse momentum are used as input to train the DL models. The DL models did remarkably well in predicting $N_{\mathrm{part}}$ values with CNN slightly outperforming the DNN model. The Mean Squared Logarithmic Error (MSLE) for the CNN model (Model-4) is determined to be 0.0592 for minimum bias collisions and 0.0114 for 0-60\% centrality class, indicating that the model performs better for semi-central and central collisions. Furthermore, the studied DL model is proven to be robust to changes in energy as well as model parameters of the input. The current study demonstrates that the data-driven technique has a distinct potential for determining centrality in terms of the number of participants in high-energy heavy-ion collision experiments.

description: A variational scheme for the derivation of generalized, symmetry-induced continuity equations for Hermitian and non-Hermitian quantum mechanical systems is developed. We introduce a Lagrangian which involves two complex wave fields and whose global invariance under dilation and phase variations leads to a mixed continuity equation for the two fields. In combination with discrete spatial symmetries of the underlying Hamiltonian, the mixed continuity equation is shown to produce bilocal conservation laws for a single field. This leads to generalized conserved charges for vanishing boundary currents, and to divergenceless bilocal currents for stationary states. The formalism reproduces the bilocal continuity equation obtained in the special case of $\mathcal{PT}$ symmetric quantum mechanics and paraxial optics.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The objective of this research was to studying the effect of televised alcoholic beverage advertising and youngster's attitude towards drinking. A questionnaire, including five-point scale items, was designed based on previous research and distributed to three hundred eighty four (174 males and 210 females) youngsters in the range of 17-26 years of age and who lives in Addis Ababa. The participants were selected using stratified random sampling method. The findings of this study revealed that watching TV alcohol advertisements is related with alcohol use. Gender of the adolescents was also related with alcohol use. Male participants, compared to females, scored high on Entertaining Presentation, informative and credibility scale items; hence they were more likely to use alcohol as compared to their female counterparts. The result also revealed that Entertaining Presentation of alcoholic beverage ads, informative of teenagers with characters of TV alcoholic beverage ads and Credibility of alcoholic beverage message derive youngsters attitude towards drinking. Moreover, Entertaining Presentation of alcoholic beverage TV ads, informative of alcoholic beverage ads to youngsters about alcohol use were found to be significant predictors of attitude towards drinking. In addition, the result from qualitative data also showed that TV alcohol commercials encouraged youngsters to use alcohol by showing, music, dance, humor and youthful lifestyle on TV alcohol ads. Moreover, youngsters perceived drinking alcohol use as healthy lifestyle due to the fact those advertisers sent only positive outcomes of alcohol. Based on the findings of the study it has been recommended that there should be counter-advertising or Brewery-Sponsored counter-advertising which teach youngsters about the hazard of alcohol drinking and abuse. Besides this study strongly suggest that the media houses and the broadcast agency should reduce youngster's exposure of alcoholic ads by setting strict time-slots which alcoholic beverages advertisements are being aired on television. And Policy makers must prohibit alcoholic beverage televised ads, from being air during sporting events and programs that are popular among youngsters

With the light-front quark model, we calculate the tensor form factors and the momentum-distributions are accessed with two parametrization forms. Numerical results for the form factors at $q^2=0$ are derived and parameters in $q^2$ distributions are obtained through extrapolation. Our results are helpful for the analysis of new physics contributions in the heavy-to-light transition.

Specifically, we determine the diffeomorphism type of such contact manifolds in the case the fundamental group is finite cyclic, and we show that on the 5-sphere the standard contact structure is the unique subcritically fillable one. More generally, it is shown that subcritically fillable contact structures on simply connected 5-manifolds are determined by their underlying almost contact structure. Along the way, we discuss the homotopy classification of almost contact structures.

description: In VO$_2$, the explicit origin of the insulator-to-metal transition is still disputable between Peierls and Mott insulators. Along with the controversy, its second monoclinic (M2) phase has received considerable attention due to the presence of electron correlation in undimerized vanadium ions. However, the origin of the M2 phase is still obscure. Here, we study a granular VO$_2$ film using conductive atomic force microscopy and Raman scattering. Upon the structural transition from monoclinic to rutile, we observe directly an intermediate state showing the coexistence of monoclinic M1 and M2 phases. The conductivity near the grain boundary in this regime is six times larger than that of the grain core, producing a donut-like landscape. Our results reveal an intra-grain percolation process, indicating that VO$_2$ with the M2 phase is a Mott insulator.
Measurement of the Inelastic Proton-Proton Cross Section at $\sqrt{s} = 13$ TeV with the ATLAS Detector at the LHC

description: This Letter presents a measurement of the inelastic proton-proton cross section using 60 $μ$b$^{-1}$ of $pp$ collisions at a center-of-mass energy $\sqrt{s}$ of $13$ TeV with the ATLAS detector at the LHC. Inelastic interactions are selected using rings of plastic scintillators in the forward region ($2.0710^{-6}$, where $M_X$ is the larger invariant mass of the two hadronic systems separated by the largest rapidity gap in the event. In this $ξ$ range the scintillators are highly efficient. For diffractive events this corresponds to cases where at least one proton dissociates to a system with $M_X>13$ GeV. The measured cross section is compared with a range of theoretical predictions. When extrapolated to the full phase space, a cross-section of $78.1 \pm 2.9$ mb is measured, consistent with the inelastic cross section increasing with center-of-mass energy.

description: We study a variational problem for the perimeter associated with the Grushin plane, called minimal partition problem with trace constraint. This consists in studying how to enclose three prescribed areas in the Grushin plane, using the least amount of perimeter, under an additional "one-dimensional" constraint on the intersections of their boundaries. We prove existence of regular solutions for this problem, and we characterize them in terms of isoperimetric sets, showing differences with the Euclidean case. The problem arises from the study of quantitative isoperimetric inequalities and has connections with the theory of minimal clusters.

It consisted of an array of 20 enriched Li$_{2}$$ ^{100}$MoO$_4$ bolometers and 20 Ge light detectors and has demonstrated that the technology of scintillating bolometers with particle identification capabilities is mature. Furthermore, CUPID-Mo can inform and validate the background prediction for CUPID. In this paper, we present a detailed model of the CUPID-Mo backgrounds. This model is able to describe well the features of the experimental data and enables studies of the $2νββ$ decay and other processes with high precision. We also measure the radio-purity of the Li$_{2}$$^{100}$MoO$_4$ crystals which are found to be sufficient for the CUPID goals. Finally, we also obtain a background index in the region of interest of 3.7$^{+0.9}_{-0.8}$(stat)$^{+1.5}_{-0.7}$(syst)$\times10^{-3}$counts/$Δ$E$_{FWHM}$/mol$_{iso}$/yr, the lowest in a bolometric $0νββ$ decay experiment.

description: The objective of the study is to examine the service quality provided by Dashen Bank and its effect on customer satisfaction using SERVPERF model. The research used descriptive and explanatory research design to describe the service quality dimensions and to understand the relationship between the variables. The Bank classified its branches in grades. In line with this, the study applied proportionate stratified sampling technique to determine the number of branches included in the sample from different grades and simple random sampling techniques to select the sample branches from each grade. Primary data is collected from the customers of the Bank using self-administered questionnaire. The questionnaire contained SERVPERF model with a 22 performance statements and the degree of the customers' agreement has been measured using five Likert Scale method. Quantitative research method is applied to analyze the data using Statistical Package for Social Science (SPSS) software version 20 and the data is presented in descriptive and inferential statistics. The correlation result of the study showed that there is a positive and significant relationship between service quality dimensions and customer satisfaction. The regression analysis exhibited, the service quality dimensions have significant influence on customer satisfaction except responsiveness. It also indicated that assurance is the dominant service quality dimension that has a strong relation with customer satisfaction in Dashen Bank. Key Words: Service quality, Customer satisfaction, SERVPERF, Dashen Bank

description: Long-range interacting many-body systems exhibit a number of peculiar and intriguing properties. One of those is the scaling of relaxation times with the number $N$ of particles in a system. In this paper I give a survey of results on long-range quantum spin models that illustrate this scaling behaviour, and provide indications for its common occurrence by making use of Lieb-Robinson bounds. I argue that these findings may help in understanding the extraordinarily short equilibration timescales predicted by typicality techniques.

description: The dynamics of one-dimensional quantum droplets and the landing applications of deep learning are recent research hotspots. In this work, we propose a novel time piecewise physics-informed neural networks (PINNs) to study complex dynamics on the one-dimensional quantum droplets by solving the corresponding amended Gross-Pitaevskii equation. The training effect of this network model in the long time domain is far better than that of the conventional PINNs, and each of its subnetworks is independent and highly adjustable. By using time piecewise PINNs with scarce training points, we not only study intrinsic modulation of single droplet and collision between two droplets, but also excite the breathers on droplet background. Intriguingly, we obtain an interference pattern from training result of collision between two droplets, which is a significant feature of the interplay of coherent matter waves. The numerical results showcase that different parameters may lead to completely different dynamic behaviors under the same initial condition in a nonlinear non-integrable system. Our results provide the significant guidance for intrinsic modulation of single droplet, droplet collision and breathers excitation via deep learning technology.

description: We study a system of two Higgs bound state, interacting via a real scalar Dark Matter mediating field, without imposing $Z_2$ symmetry on the DM sector of the postulated Lagrangian. The variational method in the Hamiltonian formalism of QFT is used to derive relativistic wave equations for the two-Higgs system, using a truncated Fock-space trial state. Approximate solutions of the 2-body relativistic coupled integral equations are presented, and conditions for the existence of Higgs bound states is examined in a broad parameter space of DM mass and coupling constants.
SERVICE QUALITY AND CUSTOMER SATISFACTION IN THE TRANSPORT SECTOR: A CASE STUDY OF ALLIANCE CITY BUS ENTERPRISE PLC

Year: 2017

description: Private transports are organizations established and owned by private or share company to provide transport services to the public. Most of the time these enterprises give their services to the public by collecting some amount of money which is less than the market price of the goods or services provided by them and sometimes with subsidy. Their customers are important stakeholders in organizations and their satisfaction is a priority to management. The objective of the study was conducted to assess the effect service quality has on the customers satisfaction of the enterprise. To achieve the objectives of this study, data was collected through questionnaire from a sample of 304 customers of the Enterprise. These respondents were selected using convenience sampling method. The data collected using the questionnaire were analyzed using statistical tools such as mean, percentage, table, correlation and frequency analysis. Service delivery of the Enterprise was evaluated by using service quality dimensions and Gap analysis method designed by Parasuraman et.al. (1988). The results of this evaluation indicate that, almost in all dimensions of service quality the Enterprise service provision rated as poor and customers are not satisfied except some factors within the dimensions. Generally, the finding of this study indicates that customers were not satisfied by overall service provision of the Enterprise and the service quality declined. Based on the findings of the study, the researcher forwards some recommendations like maintaining effective complaint handling, train employees, advise the employees about the service delivering system and customer handling procedure to serve their customers in proper way that help to improve the Enterprise service delivery position

description: A combination of competing exchange interactions and substitutional disorder gives rise to magnetic inhomogeneities in the [Y$_{2-x}$Mn$_x$]MnMnMn$_4$O$_{12}$ $x = 0.23$ and $x = 0.16$ quadruple perovskite manganites. Our neutron powder scattering measurements show that both the $x = 0.23$ and $x = 0.16$ samples separate into two distinct magnetic phases; below T$_{1}$ = 120 $\pm$ 10 K the system undergoes a transition from a paramagnetic phase to a phase characterised by short range antiferromagnetic clusters contained in a paramagnetic matrix, and below T$_{2}$ $\sim$ 65 K, the system is composed of well correlated long range collinear ferrimagnetic order, punctuated by short range antiferromagnetic clusters. A sharp increase in the antiferromagnetic phase fraction is observed below $\sim$ 33 K, concomitant with a decrease in the ferrimagnetic phase fraction. Our results demonstrate that the theoretically proposed AFM phase is stabilised in the [Y$_{2-x}$Mn$_x$]MnMnMn$_4$O$_{12}$ manganites in the presence of dominant B-B exchange interactions, as predicted.

description: Ethiopia achieved promising progress in health sector after developing HSDP and health extension program. However, implementing some selected components of Reproductive Health program, specifically FP, ANC, delivery and postnatal care; and immunization, that are given emphasis in the RH strategies for the year 2006 to 2015, assumed to be challenging in densely populated rural kebele. Hence, this study was conducted with the main objective of assessing the challenges that impeded the implementation of RH and related programs. Across sectional community- based research design backed by qualitative in-depth interviews and FGDs were used. In addition, both descriptive and exploratory method was set from May 12 to July 10, 2014 at Mokonisa kebele(in Wonago wereda, Gedeo zone of SNNPR, Ethiopia).The study population consisted of all married women in reproductive age registered in the kebele administration office in the list of conventional households. To this end, 360 women samples were included in the study, pre test questionnaire was administered. The collected data were entered and analyzed by SPSS 16.0.The qualitative data was also analyzed through non- tactical bases in their thematic areas. The result of the study showed that RH services in general were under- utilized in the study area attributed to socio economy barriers and inadequate resources in health facilities; weak information channel, negligence to adolescents RH, practices of early marriage. As a result, special attention needs to be given to the most densely populated kebele, the study area, by mobilizing relevant stakeholders and deploying adequate resources so as to surmount the challenges and bring sustainable demographic transition that can enhance socio-economic change in the study area

description: The present paper demonstrates how a natural crack mosaic resembling a random tessellation evolves with repeated 'wetting followed by drying' cycles. The natural system here is a crack network in a drying colloidal material, for example, a layer of mud. A spring network model is used to simulate consecutive wetting and drying cycles in mud layers until the crack mosaic matures. The simulated results compare favourably with reported experimental findings. The evolution of these crack mosaics has been mapped as a trajectory of a 4-vector tuple in a geometry-topology domain. A phenomenological relation between energy and crack geometry as functions of time cycles is proposed based on principles of crack mechanics. We follow the crack pattern evolution to find that the pattern veers towards a Voronoi mosaic in order to minimize the system energy. Some examples of static crack mosaics in nature have also been explored to verify if nature prefers Voronoi patterns. In this context, the authors define new geometric measures of Voronoi-ness of crack mosaics to quantify how close a tessellation is to a Voronoi tessellation, or even, to a Centroidal Voronoi tessellation.
