description: We have performed $^{119}$Sn-NMR measurements on the antiperovskite oxide superconductor Sr$_{3-x}$SnO to investigate how its normal state changes with the Sr deficiency. A two-peak structure was observed in the NMR spectra of all the measured samples. This suggests that the phase separation tends to occur between the nearly stoichiometric and heavily Sr-deficient Sr$_{3-x}$SnO phases. The measurement of the nuclear spin-lattice relaxation rate $1/T_1$ indicates that the Sr-deficient phase shows a conventional metallic behavior due to the heavy hole doping. In contrast, the nearly stoichiometric phase exhibits unusual temperature dependence of $1/T_1$, attributable to the presence of a Dirac-electron band.

description: It is shown that in extremely anisotropic layered superconductors the interaction of vortex lines with a parallel planar surface, which for straight lines along the c-axis decreases exponentially over the in-plane penetration depth $λ$, becomes a long-range dipole--dipole attraction when the vortex line is distorted randomly. This novel long-range fluctuation-induced attraction enhances the thermal fluctuations down to depths much larger than $λ$ and may lead to flux creep towards the surface.

description: Three independent predictions follow from postulating the existence of protons co-accelerated with electrons in extragalactic jets (i) multi-TeV gamma ray emission from nearby blazars, (ii) extragalactic cosmic ray protons up to 10^20 eV, and (iii) extragalactic neutrinos up to 5 10^18 eV. Recent gamma ray observations of Mrk 421 and Mrk 501 employing the air-Cerenkov technique are consistent with the predicted gamma ray spectrum, if one corrects for pair attenuation on the infrared background. Prediction (ii) is consistent with cosmic ray data, if one requires that jets are responsible for at least a sizable fraction of the extragalactic gamma ray background. With kubic kilometer neutrino telescopes, it will be possible to test (iii), although the muon event rates are rather low. Neutrino oscillations can increase the event rate by inducing tau-cascades removing the Earth shadowing effect.

description: We calculate the baryon asymmetry generated at the electroweak phase transition in the minimal supersymmetric standard model, using a new method to compute the CP-violating asymmetry in the Higgsino flux reflected into the unbroken phase. The method is based on a Higgs insertion expansion. We find that the CP asymmetry at leading order is proportional to the change in $\tan β$ in the bubble wall, which is at most of order $10^{-2}$, while at next-to-leading order this suppression factor disappears. This result may enhance the final baryon asymmetry generated during the electroweak phase transition for small $Δβ(< 10^{-3}$).

description: The modification and amplification of the gluon angular distribution produced along with hard jets in nuclear collisions is computed. We consider the limit of a thin quark-gluon plasma, where the number of rescatterings of the jet and gluons is small. The focus is on jet quenching associated with the formation of highly off-shell partons in hard scattering events involving nuclei. The interference between the initial hard radiation amplitude, the multiple induced Gunion-Bertsch radiation amplitudes, and gluon rescattering amplitudes leads to an angular distribution that differs considerably from both the standard DGLAP evolution and from the classical limit parton cascading. The cases of a single and double rescattering are considered in detail, and a systematic method to compute all matrix elements for the general case is developed. A simple power law scaling of the angular distribution with increasing number of rescatterings is found and used for estimates of the fractional energy loss as a function of the plasma thickness.

Abstract: In a domain dealing with risks associated with the often quoted fast-changing technological landscape, it is surprising that one of the main tools we rely on has been more or less stable for so long. More or less? DROID signature patterns undergo changes as identification methods improve. The question at hand is how frequent those changes and updates are and what their impact is. The poster presents the findings of a brief study taking a closer look at DROID signature pattern changes over the course of time.

description: Recent technical progress demonstrates the possibility of stacking together virtually any combination of atomically thin crystals of van der Waals bonded compounds to form new types of heterostructures and interfaces. As a result, there is the need to understand at a quantitative level how the interfacial properties are determined by the properties of the constituent 2D materials. We address this problem by studying the transport and optoelectronic response of two different interfaces based on transition-metal dichalcogenide monolayers, namely WSe2-MoSe2 and WSe2-MoS2. By exploiting the spectroscopic capabilities of ionic liquid gated transistors, we show how the conduction and valence bands of the individual monolayers determine the bands of the interface, and we establish quantitatively (directly from the measurements) the energetic alignment of the bands in the different materials as well as the magnitude of the interfacial band gap. Photoluminescence and photocurrent measurements allow us to conclude that the band gap of the WSe2-MoSe2 interface is direct in k space, whereas the gap of WSe2/MoS2 is indirect. For WSe2/MoSe2, we detect the light emitted from the decay of interlayer excitons and determine experimentally their binding energy using the values of the interfacial band gap extracted from transport measurements. The technique that we employed to reach this conclusion demonstrates a rather-general strategy for characterizing quantitatively the interfacial properties in terms of the properties of the constituent atomic layers. The results presented here further illustrate how van der Waals interfaces of two distinct 2D semiconducting materials are composite systems that truly behave as artificial semiconductors, the properties of which can be deterministically defined by the selection of the appropriate constituent semiconducting monolayers.

description: The morphology of epitaxial structures formed in solidification of liquid Au films on the Au(110) surface was studied by molecular dynamics simulation based on a many--body interatomic potential. The (1x2) reconstructed and smooth phase at the temperature T=500 K, as well as a deconstructed and rough phase of the Au(110) substrate at T=900 K, were investigated. The three--dimensional islands with the (111) oriented facets were formed in solidification of thinner liquid films. At the same time, the substrate below these islands underwent a weak faceting process. Conversely, the solidification of thicker liquid films resulted in the flat solid films. The two surface phases of the Au(110) substrate induced different structure of these epitaxial solid films. The films were studied via construction of the Voronoi polyhedra, density profiles, and surface stress calculations.

description: Abstract


The Gedeo and Sidama are neighboring communities well known in Ethiopia for their indigenous agroforestry system. Both communities have strong attachments to the indigenous agroforestry system. However, in recent years, there has been a dramatic change in the agroforestry system of both communities: a shift in the value system and economic engagements that reflects a departure from the culturally embedded local knowledge, belief, norms, and environmental ethics of regulating the human-nature relationships. This paper attempts to show the eco-cultural shift in the indigenous agroforestry systems of the Gedeo and Sidama communities. The paper specifically addresses the relationship between nature and culture, and their dynamics and the challenges related to the eco-cultural shifts in the everyday lives of the communities. Methodologically, qualitative research methods such as in-depth interviews, observation, focused group discussions; narrative interview and review of secondary sources have been employed to collect data. Purposive and snowball sampling techniques have been used to find key informants in the study areas. The results have shown that various factors such as disease to native crops, erosion of traditional social structures, urbanization, modernization, modern schooling and expansion of mainstream religions have been inducing adverse effects in the indigenous agroforestry system of Gedeo and Sidama communities. In addition, with the “monetization” of the production system in the area, the indigenous agroforestry system of the Gedeo and Sidama is now shifting towards cash-oriented cropping system. As a result, the communities have started to experience ecological, social and institutional challenges. Ecologically, the communities have started to experience loss of biodiversity, infertility of soil and food insecurity; socially, uncommon and abnormal behaviors such as beggary, snatching and prostitution are on the rise; institutionally, the decay of indigenous social institutions that preserved society-nature symbiosis is quite visible. The paper recommends necessary preventive measures to reduce drivers of eco-cultural shift in the indigenous land use systems of Gedeo and Sidama and their adverse effects on the harmonious relationship between society and nature in the areas.
Screening effects on the elastic nucleon-nucleon cross section in relativistic nuclear matter

Year: 1997

description: We investigate the screening effects on the nucleon-nucleon elastic cross section inside nuclear matter at zero and finite temperature. The N-N interaction is described phenomenologically via meson exchanges ($σ$, $π$ and $ω$) in the framework of a relativistic lagrangian model. The expressions for the in-medium meson propagators, which take into account the effects of matter polarization and renormalized vacuum polarization, are used in the calculation of the various meson contributions to the total cross section in the one-boson exchange approximation. The final expressions allow a satisfactory fit of the Coulomb substracted proton-proton cross section data in vacuum. At finite density or temperature the cross section is reduced as compared to the vacuum values and compatible with the existing experimental constraints. At high density the $p$-$p$ differential cross section gets increasingly forward and backward peaked. The $σ$-$ω$ mixing plays a key role in the understanding of the results.

description: The domain of validity of the Coulomb-Corrected Strong Field Approximation (CCSFA) is going to be analyzed in relation to the semi-classical dynamics of electrons during ionization of hydrogen-like targets. Our analysis is limited to ionization driven by Ti-sapphire laser pulses with intensities up to roughly 10$^{14}$ Wcm$^{-2}$. For such parameters, the effects related to radiation pressure are small and the laser field can be described in the dipole approximation. By applying the Magnus expansion for the exact retarded electron propagator we obtain an {\it effective action} which is free of Coulomb singularities and branch points when the complex-time trajectories are used. Furthermore, we show that the classical action is exactly recovered as the asymptotic limit of its effective counterpart. The applicability of such limit is also discussed.

description: Using a self-consistent delta-hole model the pion propagation in isospin asymmetric nuclear matter is studied. In neutron-rich matter, corresponding to heavy nuclei, a significant difference in positive and negative pion light-cone distributions is obtained leading to a nuclear enhancement of up antiquark distribution compared to the down antiquark one. This means that the sea-quark asymmetry in the free nucleon cannot be extracted model independently from an experiment on a neutron-rich nucleus.

description: Studying the stellar mass, age, luminosity, star-formation rate, and impact parameter of quasar absorber host galaxies can aid in the understanding of galaxy formation and evolution as well as in testing their models. We derive the Spectral Energy Distribution (SED) and impact parameter limits of low redshift ($z_{abs} = 0.37 - 0.55$) Mg II absorbers and of higher redshift ($z_{abs} = 1.0 - 2.5$) 2175 Å dust absorbers (2DAs). We use an imaging stacking technique to statistically boost the signal-to-noise ratio (SNR) to increase detection of the absorber host galaxies. The point spread function of the background quasar is modeled with Principal Component Analysis (PCA). This method efficiently reduces the uncertainty of traditional PSF modeling. Our SED for Mg II absorbers indicates that low redshift Mg II absorber host galaxies are likely star-forming galaxies transitioning into red quiescent galaxies, with a low star formation rate of 2.2 $M_\odot$ $yr^{-1}$. From the stacked images and simulations, we show that the average impact parameter of 2DAs is > 5 times smaller than that of Mg II absorbers, at < 7 kpc instead of Mg II absorbers' 48 kpc, indicating that 2DAs are likely associated with disk components of high redshift galaxies. This means that 2DAs are likely good probes to study precursors to the Milky Way.

description: Abstract


Home-gardens contribute a lot to the fulfillment of ecological, socioeconomic, and cultural functions and local community needs. This study was conducted with the main objective of assessing the composition and measuring diversity of plant species grown in home-gardens of Uba-Debretsehay district, southern Ethiopia. Six sampling kebeles were purposively selected. 90 households were considered in this study for data collection. A total of 87 plant species belonging to 40 plant families were documented in the sampled homegardens. Family-wise distribution showed that Fabaceae and Poaceae were the richest families concerning the number of plant species each represents. The home-garden plants documented in Uba-Debretsehay have a range of use values including food, medicine, cash, ornament, spice, and construction. Regarding altitude, Ensete ventricosum, a staple food, was cultivated in home-gardens situated in highland and midland areas. Coffea arabica, various fruits, and vegetables were cultivated in midland areas of the study area while Mussa paradisca, Mangifera indica, and Saccharum officinarum were cultivated at lower altitude areas. Home-gardens in Uba-Debretsehay district consist of different varieties of plant species and serve as a basic agro-ecosystem required for the cultivation and conservation of various plant species. Home-gardens situated in Kolla agroecology have relatively a higher diversity than home-gardens in Woynadega and Dega agro-ecology; however, the overall diversity is low. Agronomists, researchers as well as other concerned bodies need to contribute to conserving plant species cultivated in the home-gardens of the study area and maintaining their diversity to protect them from getting impacted by various factors (natural/environmental and man-made factors).

Hyperfine splittings for singly charmed baryons are found to be in agreement with expectations from the quark model and with a magnitude slightly larger than experimental values. Masses of doubly charmed baryons are also calculated and compared to a variety of model calculations.

description: For decades, Participatory Action Research (PAR) has been extended as a scientific praxisapplied in different contexts, characterised by the involvement of participating groups andoriented towards social transformation. However, there is a certain dialectical tensionbetween those approaches that emphasise the method versus those that emphasise thepursuit of social change from a decolonial perspective. This article questions how thispraxis is reflected in scientific transfer, analysing not only the development and scope of scientific production in PAR, but also how the academy may reproduce relations inherentto coloniality in this transfer. To this end, the production on PAR hosted on the Web ofScience (WoS) is collected, and a bibliometric analysis is performed by applying descriptiveand relational techniques using VosViewer software. The study concludes thatscientific production has not stopped growing and that the areas of knowledge where it isapplied have diversified. However, it also points out how the knowledge productionmodel reproduces the power relations of coloniality, affecting PAR’s transfer. Thisanalysis can contribute to the debate on a scientific approach oriented to improveprocesses of social transformation.

description: Abstract


Land-use land covers are not static rather they are dynamic in response to various driving forces. The main objective of this study was to assess land use land cover changes of Minjar-Shenkora Woreda during the three decades (1987–2017). Three different Landsat satellite data sets (Landsat 5 TM, 7 ETM+ and 8 OLI-TIRS) of 1987, 2003 and 2017 were used from the United States Geological Survey (USGS), respectively. The data were processed, and the land use land cover classes were also identified using ERDAS Imagine (ver. 2014) and Arc GIS (Ver.10.3). The study revealed that forest and shrub lands have diminished from 32885 hectaresto 16034 hectaresand 61939 hectaresto 32530 hectares, respectively while agriculture and bare lands have increased from 52524 hectaresto 90859 hectaresand 3018 hectares to7441 hectares, respectively. Moreover, built up areas also have encroached farm lands and bush lands. Over utilization of wood for fuel and construction materials, human induced fire and uncontrolled grazing, population and socio-economic changes are the main causes of the land use land cover changes. On the other hand, people’s livelihood vulnerabilities and degradation are the main outcomes of the land use land cover changes. Thus, the concerned bodies of the Woreda along with the communities should discuss and formulate law that can help to protect and preserve natural vegetation, expansion of farm lands to marginal lands as well as prevent invading of farmlands by urban horizontal expansion.

description: The electrical Hall effect is the production of a transverse voltage under an out-of-plane magnetic field. Historically, studies of the Hall effect have led to major breakthroughs including the discoveries of Berry curvature and the topological Chern invariants. In magnets, the internal magnetization allows Hall conductivity in the absence of external magnetic field. This anomalous Hall effect (AHE) has become an important tool to study quantum magnets. In nonmagnetic materials without external magnetic fields, the electrical Hall effect is rarely explored because of the constraint by time-reversal symmetry. However, strictly speaking, only the Hall effect in the linear response regime, i.e., the Hall voltage linearly proportional to the external electric field, identically vanishes due to time-reversal symmetry. The Hall effect in the nonlinear response regime, on the other hand, may not be subject to such symmetry constraints. Here, we report the observation of the nonlinear Hall effect (NLHE) in the electrical transport of the nonmagnetic 2D quantum material, bilayer WTe2. Specifically, flowing an electrical current in bilayer WTe2 leads to a nonlinear Hall voltage in the absence of magnetic field. The NLHE exhibits unusual properties sharply distinct from the AHE in metals: The NLHE shows a quadratic I-V characteristic; It strongly dominates the nonlinear longitudinal response, leading to a Hall angle of about 90 degree. We further show that the NLHE directly measures the "dipole moment" of the Berry curvature, which arises from layer-polarized Dirac fermions in bilayer WTe2. Our results demonstrate a new Hall effect and provide a powerful methodology to detect Berry curvature in a wide range of nonmagnetic quantum materials in an energy-resolved way.

description: Abstract


The main objective of this research was to investigate the socioeconomic and human rights status of the irregular cross-border Ethiopian migrants in Sudan. The research targeted identifying key policy lessons that could contribute to the existing endeavors of managing migration and preventing human trafficking and smuggling of migrants. Data were collected through desk reviews, informant interviews, group discussions, and observations. The results show that Ethiopian emigrants in Khartoum have been suffering beginning from their origin, en route, and destination. The most common drivers of the emigrants are found to be an amalgam of socioeconomic, political, and environmental factors as well as pseudo-success-stories of the pioneer migrants. The en route was perilous for the migrants in which they faced physical assault, confinement, mistreatment, sexual abuse, and robbery. At the destination, the emigrants had been suffering from religion-based disparagement, nationality-based stigmatization, restricted mobility, exploitative working conditions, confiscation of resources, sexual abuse, vulnerability to drug dependence, and maltreatment. The mechanism to alleviate the problem is triple: one is expected from Ethiopia, the other from Sudan, and the third is a combined effort. In Ethiopia, enhanced democratic culture, political tolerance, good governance, improved access to legal travel authorization (visa) for safe migration, awareness creation campaigns, enhanced monitoring of the private employment agencies, and increased cooperation among stakeholders are found to be vital solutions to prevent illicit cross-border human trafficking and smuggling of migrants. Sudan is recommended to comply with the international conventions it ratified and the national legal frameworks it enforced regarding human trafficking, smuggling of migrants, and refugee protection. Ethiopia and Sudan have also something great to do together to combat the quandary of illicit migration: abolition of visa obligation for the citizens of one another and establishing robust co-managed border supervision command post mandated to address conflicts, irregular migration, and displacement at border areas.

description: We study three models of driven sandpile-type automata in the presence of quenched random defects. When the dynamics is conservative, all these models, termed the random sites (A), random bonds (B), and random slopes (C), self-organize into a critical state. For Model C the concentration-dependent exponents are nonuniversal. In the case of nonconservative defects, the asymptotic state is subcritical. Possible defect-mediated nonequilibrium phase transitions are also discussed.

description: Simply put, a sparse polynomial is one whose zero coefficients are not explicitly stored. Such objects are ubiquitous in exact computing, and so naturally we would like to have efficient algorithms to handle them. However, with this compact storage comes new algorithmic challenges, as fast algorithms for dense polynomials may no longer be efficient. In this tutorial we examine the state of the art for sparse polynomial algorithms in three areas: arithmetic, interpolation, and factorization. The aim is to highlight recent progress both in theory and in practice, as well as opportunities for future work.

description: Abstract


Low soil fertility and poor crop management practices are among the major constraints limiting the productivity of bread wheat in Ethiopia in general and Hulbareg District in particular. Therefore, a field experiment was conducted in Hulbareg District during the 2019 main cropping season to evaluate the effect of blended NPSB fertilizer rates on yield and yield components and to determine the economically feasible rates for bread wheat production. Factorial combination of three improved bread wheat varieties (Ogolcho, Kekeba and Kingbird) and five rates of NPSB fertilizers (0, 50, 100, 150 and 200) were laid out in randomized complete block design with three replications. The results revealed that the plant height, number of kernels per spike, thousand kernel weight, straw yield, number of total tillers and productive tillers were substantially (P <0.01) affected by the main effects of NPSB.. The interaction effect of fertilizer and variety was also statistically affected the days to physiological maturity, total aboveground dry biomass and grain yield. The maximum grain yield (6500 kg ha−1) and above ground dry biomass kg ha−1 (15389), were recorded at the combination of the highest rates of NPSB, i.e., 200 kg with variety Ogolcho. Generally, the economic feasibility of the fertilizer over varieties combination indicated that application of 200 kg NPSB ha−1 to Kekeba variety resulted in maximum marginal rates of return of 4202%. The partial budget analysis revealed that the highest net return (72, 495 Birr ha−1) with MRR 2711.9% was obtained for Ogolcho from application of 200 kg NPSB ha−1. Based on the result of this study, it can be concluded that bread wheat variety Ogolcho and NPSB rate of 200 kg ha−1 to be appropriate for bread wheat production in the study area.

description: Improved potential solutions are presented for the inverse scattering problem for $d$+$^4$He data. The input for the inversions includes both the data of recent phase shift analyses and phase shifts from RGM coupled-channel calculations based on the NN Minnesota force. The combined calculations provide a more reliable estimate of the odd-even splitting of the potentials than previously found, suggesting a rather moderate role for this splitting in deuteron-nucleus scattering generally. The approximate parity-independence of the deuteron optical potentials is shown to arise from the nontrivial interference between antisymmetrization and channel coupling to the deuteron breakup channels. A further comparison of the empirical potentials established here and the double folding potential derived from the M3Y effective NN force (with the appropriate normalisation factor) reveals strong similarities. This result supports the application of the double folding model, combined with a small Majorana component, to the description even of such a loosely bound projectile as the deuteron. In turn, support is given for the application of iterative-perturbative inversion in combination with the double folding model to study fine details of the nucleus-nucleus potential. A $d$-$^4$He tensor potential is also derived to reproduce correctly the negative $^6$Li quadrupole moment and the D-state asymptotic constant.
