description: We use the two-flavor linear sigma model with quarks to study the phase structure of isospin asymmetric matter at zero temperature. The meson degrees of freedom provide the mean field chiral- and isospin-condensates on top of which we compute the effective potential accounting for constituent quark fluctuations at one-loop order. Using the renormalizability of the model, we absorb the ultraviolet divergences into suitable counter-terms that are added respecting the original structure of the theory. These counter-terms are determined from the stability conditions which require the effective potential to have minima in the condensates directions at the classical values, as well as the transition from the non-condensed to the condensed phase to be smooth as a function of the isospin chemical potential. We use the model to study the evolution of the condensates as well as the pressure, energy and isospin densities and the sound velocity as functions of the isospin chemical potential. The approach does a good average description up to isospin chemical potentials values not too large as compared to the vacuum pion mass.

description: Two-band electronic structures with a valence and a conduction band separated by a tunable energy gap and with pairing of electrons in different channels can be relevant to investigate the properties of two-dimensional multiband superconductors and electron-hole superfluids, as monolayer FeSe, recently discovered superconducting bilayer graphene, and double-bilayer graphene electron-hole systems. This electronic configuration allows also to study the coexistence of superconductivity and charge density waves in connection with underdoped cuprates and transition metal dichalcogenides. By using a mean-field approach to study the system above mentioned, we have obtained numerical results for superconducting gaps, chemical potential, condensate fractions, coherence lengths, and superconducting mean-field critical temperature, considering a tunable band gap and different filling of the conduction band, for parametric choice of the pairing interactions. By tuning these quantities, the electrons redistribute among valence and conduction band in a complex way, leading to a new physics with respect to single-band superconductors, such as density induced and band-selective BCS-BEC crossover, quantum phase transitions, and hidden criticalities. At finite temperature, this phenomenon is also responsible for the non-monotonic behavior of the superconducting gaps resulting in a superconducting-normal state reentrant transition, without the need of disorder or magnetic effects.

description: We use the recently modified Friedmann equations obtained from string T-duality effects that encode the zero-point length (Phys. Lett. B 836 (2023), 137621) to study the phase space analyses of a bouncing early universe. An important implication of such stringy effects is that they can alleviate the initial singularity since the Raychaudhuri equation is modified. We investigate if the Universe can undergo an accelerated expansion phase for a specific domain of the equation of state parameter. The stringy effects are encoded in the parameter $Γ$, which depends not only on the zero-point length but also on the state parameter $ω$. We construct two dynamical systems depending on whether $-1 < ω\leq -1/3$ and $ω\geq -1/3$, and we classify the equilibrium points of each system. Exact solutions and cosmological implications are discussed.

description: We investigate the non-universal part of the orbital entanglement spectrum (OES) of the nu = 1/3 fractional quantum Hall effect (FQH) ground-state with Coulomb interactions. The non-universal part of the spectrum is the part that is missing in the Laughlin model state OES whose level counting is completely determined by its topological order. We find that the OES levels of the Coulomb interaction ground-state are organized in a hierarchical structure that mimic the excitation-energy structure of the model pseudopotential Hamiltonian which has a Laughlin ground state. These structures can be accurately modeled using Jain's "composite fermion" quasihole-quasiparticle excitation wavefunctions. To emphasize the connection between the entanglement spectrum and the energy spectrum, we also consider the thermodynamical OES of the model pseudopotential Hamiltonian at finite temperature. The observed good match between the thermodynamical OES and the Coulomb OES suggests a relation between the entanglement gap and the true energy gap.

description: The current concerted efforts of Ethiopian government for the establishment of  IWM  in every
rural areas  is an emerging agricultural development and  rural livelihood  strategy aiming at
developing  environmental protection and enhancing  rural  households income  through
participating them on rural developmental activities for improving agricultural production and
productivity. This study was conducted to examine the current status of IWM in relation to its
structure and community participation on watershed development based activities, to identify
the main challenges, to evaluate the  opportunities  of  IWM  to the livelihood of the rural
households, and to assess the institutional and implementation  related issues  of  IWM in the
study area. The study was based on descriptive survey  and followed cross sectional design
encompassing both qualitative and quantitative data. A total of 212 sample respondents were
selected  through systematic random sampling. The data were analyzed by using simple
descriptive  statistics such as percentage, frequency, tables and charts. Qualitative data were
analyzed through interpretation and conceptual generalization.  The findings of this study
indicate that  the study micro-watershed  faced various  social,  economical,  institutional and
implementation  problems that hinder the effective performances of  watershed interventions
and development projects. Of which deforestation, soil degradation, over grazing, continuous
plows, less contact between agricultural experts and farmers are the main determinant.
Furthermore, poor education status of the respondent and farmers lack awareness of carrying
responsibility is the other challenging factors for the adoption and implementation of IWM
practices. For that reason, limited training and technical support of agricultural experts/DAs,
poor planning and identification of problems, lack of proper follow up, lack of organization, proper implementation problems, lack of coordination between farmers and DAs, lack of
support from NGO’s,  limited use of proper management techniques for varying landscape,
administrative problem and failure of the committee in mobilizing the community are the main
institutional and implementation constraints in the study area.  Therefore, the  district
agriculture and rural development offices and every concerned stakeholder should take into
consideration the social, economical, institutional and implementation constraints affected the
effective functioning of IWM program/projects.

description: We analyse the general structure of the three-point functions of conserved higher-spin supercurrents in 3D, $\mathcal{N}=1$ superconformal field theory. It is shown that supersymmetry imposes additional restrictions on correlation functions of conserved higher-spin currents. We develop a manifestly supersymmetric formalism to compute the three-point function $\langle \mathbf{J}^{}_{s_{1}} \mathbf{J}'_{s_{2}} \mathbf{J}''_{s_{3}} \rangle$, where $\mathbf{J}^{}_{s_{1}}$, $\mathbf{J}'_{s_{2}}$ and $\mathbf{J}''_{s_{3}}$ are conserved higher-spin supercurrents with superspins $s_{1}$, $s_{2}$ and $s_{3}$ respectively (integer or half-integer). Using a computational approach limited only by computer power, we analytically impose the constraints arising from the superfield conservation equations and symmetries under permutations of superspace points. Explicit solutions for three-point functions are presented and we provide a complete classification of the results for $s_{i} \leq 20 $; the pattern is very clear, and we propose that our classification holds for arbitrary superspins. We demonstrate that Grassmann-even three-point functions are fixed up to one parity-even structure and one parity-odd structure, while Grassmann-odd three-point functions are fixed up to a single parity-even structure. The existence of the parity-odd structure in the Grassmann-even correlation functions is subject to a set of triangle inequalities in the superspins. For completeness, we also analyse the structure of three-point functions involving conserved higher-spin supercurrents and scalar superfields.

description: Education is the process  in which Knowledge and skill transferred to other people through
discussion, teaching and research. It plays a significant role for the civilization,
modernization and  development of any country.  Ethiopia has a long and rich history of
educational  traditions such as Indigenous, Religious and Modern education in Ethiopia. The
study was confined to Sendafa Preparatory School in Special Zone of Oromia state of
Ethiopia. It employed mixed-method approaches and descriptive survey design. Among 183
social science learners 126 learners were sampled through lottery sampling technique. But
all Geography teachers and departmental heads were taken as the main participants through
purposive sampling techniques. Questionnaire, structured interviews, observation and
documents were the main data collection instruments for the study. Data that were collected
through close-ended questionnaires were edited, coded, classified, tabulated and organized
in the form of tables have been analyzed through frequency, percentage and mean via SPSS
software. However, data that were collected through interviews, observation and open-ended
questionnaire were analyzed inductively using narrations and descriptions through words,
phrases and statements, whereas the data collected from documents were organized in the
form of tables and analyzed via percentage.  Based on the analyzed data, findings were
depicted. The finding of the study revealed that majority  of teachers’ frequently practice
teacher-centered method teaching, teachers’ failure to utilize teaching materials, shortage of
time, poor teacher-student relationship, teachers failed to measure learners’ academic
progress through continuous assessment techniques, absence of plasma TV transmission and
dearth of instructional resources  such as reference books, pedagogical centre, scarcity of
budget were considerable hindrances on the implementation of Geography syllabus through
the participatory approaches  of teaching methods. Based on the findings of the study,
recommendations were made to the concerned bodies to alleviate problem of the quality of
teaching-learning process in Geography participatory teaching approach and utilization of
resource upgrade the quality of education and increase learners’ achievement.

description: A simple constituent model of gluodynamics that is motivated by lattice field theory and the QCD Hamiltonian in Coulomb gauge is applied to descriptions of hybrid meson flavor mixing and vector hybrid configuration mixing. Good agreement with lattice gauge computations is obtained for flavor multiplet masses, while mixing angles are in approximate agreement, given large errors. The configuration mixing results are also in rough agreement with lattice NRQCD calculations. Thus the viability of constituent gluon models of hybrid hadrons and glueballs is supported. The results suggest that a flavor multiplet of vector hybrids should appear with masses of approximately 2100, 2200, and 2300 MeV and that the isovector vector hybrid decay constant is about 20 MeV. Similarly, the $π_1$ exotic hybrid should have isospin partner states near 1760 and 1900 MeV, and it is suggested that the recently seen $η_1$ hybrid signal is the latter state.

description: Globally, forests cover about four billion hectares. Ethiopia forest cover is about 3% of the
total land area which is far much below the internationally recommended 10% per country.
More than 1.6 billion people globally depend on forests for their livelihood. Ethiopia is one
of the worlds fastest population growth accelerated environmental degradation and
structural food insecurity. In Ethiopia the factors accelerated forest resource degradation
has the major threat to rural livelihoods and sustainable natural resource management in the
country. The objective of study of this study is to determine socio-economic factors affecting
sustainable management of Gorte forest, assess to current forest conservation activity. A
descriptive research design was used. Purposive sampling was used in the study and the
sample size was 182 respondents, Data was collected using questionnaire, satellite image,
interview and observation. Data was analyzed using descriptive analysis by the help of
statistical package for social sciences. The stakeholders are not adequately involved in forest
management. The major causes of deforestation in study area were agricultural land
expansion, cutting down of tree for fuel wood and charcoal production, settlement expansion
and timber harvest for construction purpose. Efforts should thus be focused on those factors
that affect sustainable management of the forest.

description: Moiré physics plays an important role for the characterization of functional materials and the engineering of physical properties in general, ranging from strain-driven transport phenomena to superconductivity. Here, we report the observation of moiré fringes in conductive atomic force microscopy (cAFM) scans gained on the model ferroelectric Er(Mn,Ti)O$_3$. By performing a systematic study of the impact of key experimental parameters on the emergent moiré fringes, such as scan angle and pixel density, we demonstrate that the observed fringes arise due to a superposition of the applied raster scanning and sample-intrinsic properties, classifying the measured modulation in conductance as a scanning moiré effect. Our findings are important for the investigation of local transport phenomena in moiré engineered materials by cAFM, providing a general guideline for distinguishing extrinsic from intrinsic moiré effects. Furthermore, the experiments provide a possible pathway for enhancing the sensitivity, pushing the resolution limit of local transport measurements by probing conductance variations at the spatial resolution limit via more long-ranged moiré patterns.

description: We evaluate optimized parallel sparse matrix-vector operations for two representative application areas on widespread multicore-based cluster configurations. First the single-socket baseline performance is analyzed and modeled with respect to basic architectural properties of standard multicore chips. Going beyond the single node, parallel sparse matrix-vector operations often suffer from an unfavorable communication to computation ratio. Starting from the observation that nonblocking MPI is not able to hide communication cost using standard MPI implementations, we demonstrate that explicit overlap of communication and computation can be achieved by using a dedicated communication thread, which may run on a virtual core. We compare our approach to pure MPI and the widely used "vector-like" hybrid programming strategy.

description: Ethiopia is one of the Sub-Saharan African Countries known for its fast population growth
which results in rural farmland fragmentation and land intensification. The objective of this
paper is to investigate the impacts of rapid population growth on the rural farmland
fragmentation and land use intensification in the case of Essara Woreda, Dawuro  Zone,
Southern Ethiopia. The data used in this study were collected from 119 samples household
heads of the four rural Kebele  identified via simple random sampling. The methods of data
analysis used in the study were descriptive statistics such as percentage and frequency. The
findings reveal that there  illiteracy is one of the key causes for rapid population  growth
which lead smaller farmland holding per household  in  the district. Also,  the findings show
that being involved in family planning is the best option for reducing to the future rapid
population growth. Moreover, the rapid growth of population has resulted in shortage of
farmland, and fragmentation through time and which in turn affects small holder agriculture
and sustainability of rural livelihoods. Thus, the  result calls for further interventions in
family planning to limit the rapid population growth, intensification agricultural production
and enhancing non-farm activities.

description: In this article, we solve the Duffin--Kemmer--Petiau (DKP) equation in the presence of hyperbolic tangent potential for spin-one particles. By partitioning the spin-one spinor, we show that the DKP equation is equivalent to the Klein--Gordon equation formalism. The scattering solutions are derived in terms of hypergeometric functions. The reflection $R$ and transmission $T$ coefficients are calculated in terms of the Gamma functions. The results show the presence of the superradiance phenomenon when $R$ for a specific region in the potential becomes greater than one.

description: The objective of this study was to assess urban land registration system and its contribution
to  sustainable  land  management,  and  to  identify  challenges  of  implementing  land
registration.  In  addition,  the  study  was  aimed  at  discussing  the  socio-economic  impacts  of
land  registration  system  in  the  town.  The  study  used  multi -stage  sampling  technique  to
maintain the representativeness of sample. Sample kebeles were selected by using Systematic
random  sampling  technique  and  266  households  were  selected.  To  achieve  the  research
objectives, both primary and secondary data were collected from different sources. Primary
data  sources  include  owner  occupied  households  in  selected  kebeles,  senior  experts,  and
officials  in  the  municipality,  revenue  office,  and  courts.  The  Secondary  data  sources  were
internet  web  sites,  annual  reports,  regional  regulation,  directive,  and  other  supportive
documents. The collected data were coded, edited, analyzed and interpreted. This study has
shown that the land registration system in Wolayita Sodo was not implemented properly. This
is mainly due to different factors. These include lack of Sound legal framework related to
land registration,  low level of public awareness and participation, lack of skilled man power
to  implement  land  registration  and  recording,  inadequate  material  and  financial  capacity
and  poor  coordination  and  integration  among  different  departments  and  sectors.  Lack  of
political  commitment  in  allocating  material  and  financial  resources  was  also  another
problem in implementing land registration in the town. Due to the above problems, the town
experienced low and decreasing revenue collection from land and proliferation of informal
land  occupation  and  land  speculation.  The  growing  number  of  land  disputes  was  another
impacts associated with poor land registration system and parcel boundary adjudication. To
mitigate  the  challenges  of  implementing  land  registration  in  Sodo  town,  enacting  an
appropriate legislative framework, and strengthening of man power, material and financial
capacity should be important tasks. Public awareness creation on land registration and its
importance through mass media and public meeting should be given emphasis.

Here, we collected data on identification of 100 snake species by building a week-long online citizen science challenge which attracted greater than 1000 participants from around the world. We show that a large community including both professional herpetologists and skilled avocational snake enthusiasts with the potential to quickly (less than 2 min) and accurately (69–90%; see text) identify snakes is active online around the clock, but that only a small fraction of community members are proficient at identifying snakes to the species level, even when provided with the snake's geographical origin. Nevertheless, participants showed great enthusiasm and engagement, and our study provides evidence that innovative citizen science/crowdsourcing approaches can play significant roles in training and building capacity. Although identification by an expert familiar with the local snake fauna will always be the gold standard, we suggest that healthcare workers, clinicians, epidemiologists and other parties interested in snakebite could become more connected to these communities, and that professional herpetologists and skilled avocational snake enthusiasts could organize ways to help connect medical professionals to crowdsourcing platforms. Involving skilled avocational snake enthusiasts in decision making could build the capacity of healthcare workers to identify snakes more quickly, specifically and accurately, and ultimately improve snakebite treatment data and outcomes.

description: A first-principles method is presented to calculate elastic constants up to the fourth order of crystals with the cubic and hexagonal symmetries. The method relies on the numerical differentiation of the second Piola-Kirchhoff stress tensor and a density functional theory approach to compute the Cauchy stress tensors for a minimal list of strained configurations of a reference state. The number of strained configurations required to calculate the independent elastic constants of the second, third, and fourth order is 24 and 37 for crystals with the cubic and hexagonal symmetries, respectively. Here, this method is applied to five crystalline materials with the cubic symmetry (diamond, silicon, aluminum, silver, and gold) and two metals with the hexagonal close packing structure (beryllium and magnesium). Our results are compared to available experimental data and previous computational studies. Calculated linear and nonlinear elastic constants are also used, within a nonlinear elasticity treatment of a material, to predict values of volume and bulk modulus at zero temperature over an interval of pressures. To further validate our method, these predictions are compared to results obtained from explicit density functional theory calculations.
Modelling human escape from X-chromosome inactivation in mouse
Creators: name: Peeters, Samantha
Publisher: name: University of British Columbia

description: A long-standing question concerning X-chromosome inactivation has been how some genes avoid the otherwise stable chromosome-wide heterochromatinization of the inactive X. As 20% or more of human X-linked genes escape from inactivation, such genes are important contributors to sex differences in gene expression, and identifying the mechanism by which these exceptions occur will inform our understanding of X-inactivation and broader questions of epigenetic regulation. While bioinformatic studies have generated a list of candidate features, the nature of the elements or definitive evidence that any one particular element is necessary or sufficient for a gene to escape, is still elusive and requires experimental validation. Mouse models offer a well-characterized and readily manipulated system in which to study X-inactivation and escape, but have far fewer genes and gene clusters that escape than humans. Given these differences, it was unclear whether the mechanism of escape gene regulation is conserved between species, and thus, this thesis addresses conservation of the escape process and the potential to model human escape gene regulation using mouse systems. Bacterial artificial chromosomes carrying genes known to escape from X-inactivation in humans were targeted to the Hprt locus and studied on the inactive X in mice. They were examined for escape by expression and inactivation-associated DNA methylation of promoter CpG islands. Expression from the inactive X and corresponding low promoter DNA methylation of human gene RPS4X demonstrated that the mouse system is capable of recognizing human elements. Furthermore, the escape status of the transgene remained stable between developmental time points, tissues, and individual females. A second human escape gene, KDM5C, was targeted to the Hprt locus and was surprisingly subject to inactivation, suggesting that its mechanism of escape was not conserved or that the critical elements for escape were not contained in the transgene. To further interrogate the escape elements involved in both human genes analyzed, as well as additional constructs of interest, a docking site at Hprt was generated in a female mouse embryonic stem cell line. Overall, this thesis contributed to the development of approaches to examine human escape from inactivation, and characterization of two human escape regions.

description: The Przybylski star spectrum has been studied in order to search for deuterium lines. Since this star is extremely enriched in the s-process elements, which are the product of interaction between free neutrons and seed nuclei, we might as well expect to detect deuterium in this star. However, no visible spectroscopic manifestation of deuterium has been detected. Perhaps, the reason of this result is the convective "destruction" of this isotope.

description: Ethiopia is one of the most severely affected country in the Eastern Africa particularly in
rangeland degradation. The main objective of this study was to assess the impact of rangeland
degradation on the livelihood of semi-pastoral community of Malle Woreda, South Ethiopia. A
multi-stage random sampling technique was used. Data was collected from two kebeles, namely
Goloberendo and Kenbabobo. The main source of data for the study were 169 households, 20
FGD  participants  and 10  interviewers.  The instruments used for data collection were
questionnaires, interview, focus group discussions and  GIS and remote  sensing.  The data
obtained from questionnaires were analyzed using descriptive statistics such as mean, standard
deviation, percentage,  frequency and inferential statistics, like  independent t-test and  chi-
square  test  were  employed with  the  help of SPSS  version  20. Similarly, multiple  linear
regression model  and satellite  image was  used  through STATA version 13 and GIS  and RS,
respectively.  In the current study,  finding  from  satellite image  indicated that,  rangeland  is
highly degraded.  The result showed that the  area  before three decades were  under  a good
rangeland resources are changed in to new condition of degradation.  Livestock  population,
lack of diversified income,  human population  growth, encroachment  of shrub,  overgrazing,
traditional herding, variability of rainfall and temperature  and expansion of  farm land were
found  statistically significant causes of rangeland degradation.  Besides,  the multiple  linear
regression  model  analysis  showed  that, impact of rangeland degradation on  semi-pastoral
livelihood determined by  age of households  head, family size,  access to  market,  access to
pasture, drought,  households  head education, livestock holding  size, households  annual
income, veterinary service and  households  mobility.  On the other hand, the  semi-pastoral
households develop strategies,  like mobility, selling of livestock, distribution of their livestock
to other closet households resides in different kebele, used as rangeland trees as feed resources
for their livestock, communal and private water harvest and private pasture for their milky
livestock during shortage of forage and water. In addition, non-pastoral and off-farm activities
were statistically  significant relationship  with  effects of rangeland degradation.  In order to
alleviate these problems the government, other concerned bodies, NGOs and community should
work  jointly  to  rangeland  development  and management  with the  diversification  of  semi-
pastoral livelihood of the study area.

description: In charged current weak interaction processes, neutrinos are produced in an entangled state with the charged lepton. This correlated state is disentangled by the measurement of the charged lepton in a detector at the production site. We study the dynamical aspects of disentanglement, propagation and detection, in particular the conditions under which the disentangled state is a coherent superposition of mass eigenstates. The appearance and disappearance far-detection processes are described from the time evolution of this disentangled "collapsed" state. The familiar quantum mechanical interpretation and factorization of the detection rate emerges when the quantum state is disentangled on time scales \emph{much shorter} than the inverse oscillation frequency, in which case the final detection rate factorizes in terms of the usual quantum mechanical transition probability provided the final density of states is insensitive to the neutrino energy difference. We suggest \emph{possible} corrections for short-baseline experiments. If the charged lepton is unobserved, neutrino oscillations and coherence are described in terms of a reduced density matrix obtained by tracing out an un-observed charged lepton. The diagonal elements in the mass basis describe the production of mass eigenstates whereas the off diagonal ones provide a measure of coherence. It is shown that coherences are of the same order of the diagonal terms on time scales up to the inverse oscillation frequency, beyond which the coherences oscillate as a result of the interference between mass eigenstates.

description: Land degradation has been the most serious problem that has treated the life of millions of people
in Ethiopia. The causes of land degradation are complex and diverse. Although  influenced by
natural and socio-economic factors, land degradation in Ethiopia is mainly a function of growing
population exploitative substance agriculture and rudimentary production methods but the problem
is not noticed and perceived by all farmers at the same fashion and level. Thus, the study is aimed
to  evaluate  the status of farmers‟ perception of  land degradation  and management practices in
doyogena woreda.  A  three-stage systematic sampling procedure was employed to select  three
sample kebeles and 129 sample household heads to collect primary data. Interview and observation
were also used to collect the relevant data. Descriptive statistics, chi-square analysis and Likert
scale were employed to show the frequency and percentage distribution of respondents. As the
study has been shown the farmers‟ perception of  steep slope , human population pressure, soil
erosion, deforestation, over cultivation, planting eucalyptus tree, lack of fertilizers, overgrazing,
poor farming practice and absence of crop rotation  as the  cause  of  land degradation  were found
relatively reported by majority of the respondents except few educated farmers.  For many farmers
reported that difficulty for farming increased of requirements of fertilizers, loss of agricultural
production, poverty and economic backwardness, landlessness and migration as consequence of
land degradation in study area. Concerning the perception to land management practices, closure of
grazing land,  terracing and tree planting  are said to have been the least perceived as management
practices used by farmers except those who attached their life with in education. On the other hand,
organic manure, mulching, crop rotation, and tree planting  were indicated as the frequently used
soil management practices  by large  house hold size. Pertaining the sources of information for
farmers‟ friends and relatives were found as the most important one. As the chi-square analysis has
been shown age,  education and household size  were major factors that influence perception of
farmers. Therefore, continuous education, training and disseminating information is very important
to arouse farmers‟ perception of  land degradation  and management practices by considering their
current perception level in the study area.

description: Remote sensing hyperspectral and more generally spectral instruments are common tools to decipher surface features in Earth and Planetary science. While linear mixture is the most common approximation for compounds detection (mineral, water, ice, etc...), the transfer of light in surface and atmospheric medium are highly non-linear. The exact simulation of non-linearities can be estimated at very high numerical cost. Here I propose a very simple non-linear form (that includes the regular linear area mixture) of radiative transfer to approximate surface spectral feature. I demonstrate that this analytical form is able to approximate the grain size and intimate mixture dependence of surface features. In addition, the same analytical form can approximate the effect of Martian mineral aerosols. Unfortunately, Earth aerosols are more complex (water droplet, water ice, soot,...) and are not expected to follow the same trend.
