description: We study the electronic thermal conductivity $κ_\textrm{el}$ and the thermal diffusion constant $D_\textrm{Q,el}$ in the square lattice Hubbard model using the finite-temperature Lanczos method. We exploit the Nernst-Einstein relation for thermal transport and interpret the strong non-monotonous temperature dependence of $κ_\textrm{el}$ in terms of that of $D_\textrm{Q,el}$ and the electronic specific heat $c_\textrm{el}$. We present also the results for the Heisenberg model on a square lattice and ladder geometries. We study the effects of doping and consider the doped case also with the dynamical mean-field theory. We show that $κ_\textrm{el}$ is below the corresponding Mott-Ioffe-Regel value in almost all calculated regimes, while the mean free path is typically above or close to lattice spacing. We discuss the opposite effect of quasi-particle renormalization on charge and heat diffusion constants. We calculate the Lorenz ratio and show that it differs from the Sommerfeld value. We discuss our results in relation to experiments on cuprates. Additionally, we calculate the thermal conductivity of overdoped cuprates within the anisotropic marginal Fermi liquid phenomenological approach.

description: That physisorbents can reduce the energy footprint of water vapor capture and release has attracted interest because of potential applications such as moisture harvesting, dehumidification, and heat pumps. In this context, sorbents exhibiting an S-shaped single-step water sorption isotherm are desirable, most of which are structurally rigid sorbents that undergo pore-filling at low relative humidity (RH), ideally below 30% RH. Here, we report that a new flexible one-dimensional (1D) coordination network, [Cu(HQS)(TMBP)] (H2HQS = 8-hydroxyquinoline-5-sulfonic acid and TMBP = 4,4′-trimethylenedipyridine), exhibits at least five phases: two as-synthesized open phases, α ⊃ H2O and β ⊃ MeOH; an activated closed phase (γ); CO2 (δ ⊃ CO2) and C2H2 (ϵ ⊃ C2H2) loaded phases. The γ phase underwent a reversible structural transformation to α ⊃ H2O with a stepped sorption profile (Type F-IV) when exposed to water vapor at <30% RH at 300 K. The hydrolytic stability of [Cu(HQS)(TMBP)] was confirmed by powder X-ray diffraction (PXRD) after immersion in boiling water for 6 months. Temperature-humidity swing cycling measurements demonstrated that working capacity is retained for >100 cycles and only mild heating (<323 K) is required for regeneration. Unexpectedly, the kinetics of loading and unloading of [Cu(HQS)(TMBP)] compares favorably with well-studied rigid water sorbents such as Al-fumarate, MOF-303, and CAU-10-H. Furthermore, a polymer composite of [Cu(HQS)(TMBP)] was prepared and its water sorption retained its stepped profile and uptake capacity over multiple cycles.

description: It is shown that, an entire class of off-diagonally disordered linear lattices composed of two basic building blocks and described within a tight binding model can be tailored to generate absolutely continuous energy bands. It can be achieved if linear atomic clusters of an appropriate size are side coupled to a suitable subset of sites in the backbone, and if the nearest neighbor hopping integrals, in the backbone and in the side coupled cluster bear a certain ratio. We work out the precise relationship between the number of atoms in one of the building blocks in the backbone, and that in the side attachment. In addition, we also evaluate the definite correlation between the numerical values of the hopping integrals at different subsections of the chain, that can convert an otherwise point spectrum (or, a singular continuous one for deterministically disordered lattices) with exponentially (or power law ) localized eigenfunctions to an absolutely continuous spectrum comprising one or more bands (subbands) populated by extended, totally transparent eigenstates. The results, which are analytically exact, put forward a non-trivial variation of the Anderson localization [P. W. Anderson, Phys. Rev. 109, 1492 (1958)], pointing towards its unusual sensitivity to the numerical values of the system parameters and, go well beyond the other related models such as the Random Dimer Model (RDM) [Dunlap et al., Phys. Rev. Lett. 65, 88 (1990)].

description: Nuclear scattering events with large momentum transfer in atomic, molecular, or solid-state systems may result in electronic excitations. In the context of atomic scattering by dark matter (DM), this is known as the Migdal effect, but the same effect has also been studied in molecules in the chemistry and neutron scattering literature. Here we present two distinct Migdal-like effects from DM scattering in molecules, which we collectively refer to as the molecular Migdal effect: a center-of-mass recoil, equivalent to the standard Migdal treatment, and a non-adiabatic coupling resulting from corrections to the Born-Oppenheimer approximation. The molecular bonds break spherical symmetry, leading to large daily modulation in the Migdal rate from anisotropies in the matrix elements. Our treatment reduces to the standard Migdal effect in atomic systems but does not rely on the impulse approximation or any semiclassical treatments of nuclear motion, and as such may be extended to models where DM scatters through a long-range force. We demonstrate all of these features in a few simple toy models of diatomic molecules, namely ${\rm H}_2^+$, N$_2$, and CO, and find total molecular Migdal rates competitive with those in semiconductors for the same target mass. We discuss how our results may be extended to more realistic targets comprised of larger molecules which could be deployed at the kilogram scale.

description: We perform systematic first-principles calculations of the proximity exchange coupling, induced by cobalt (Co) and nickel (Ni) in graphene, via a few (up to three) layers of hexagonal boron nitride (hBN). We find that the induced spin splitting of the graphene bands is of the order of 10 meV for a monolayer of hBN, decreasing in magnitude but alternating in sign by adding each new insulating layer. We find that the proximity exchange can be giant if there is a resonant $d$ level of the transition metal close to the Dirac point. Our calculations suggest that this effect could be present in Co heterostructures, in which a $d$ level strongly hybridizes with the valence-band orbitals of graphene. Since this hybridization is spin dependent, the proximity spin splitting is unusually large, about 10 meV even for two layers of hBN. An external electric field can change the offset of the graphene and transition-metal orbitals and can lead to a reversal of the sign of the exchange parameter. This we predict to happen for the case of two monolayers of hBN, enabling electrical control of proximity spin polarization (but also spin injection) in graphene/hBN/Co structures. Nickel-based heterostructures show weaker proximity effects than cobalt heterostructures. We introduce two phenomenological models to describe the first-principles data. The minimal model comprises the graphene (effective) $p_z$ orbitals and can be used to study transport in graphene with proximity exchange, while the $p_z$-$d$ model also includes hybridization with $d$ orbitals, which is important to capture the giant proximity exchange. Crucial to both models is the pseudospin-dependent exchange coupling, needed to describe the different spin splittings of the valence and conduction bands.

description: ABSTRACT Emotional intelligence is the ability of an individual to recognize his or her own feelings, rationalize among those feelings as well as incorporate such feelings into thinking and actions. Psychological well-being is recognized as the capability to actively participate in work and to create important relationships with others, and to establish positive emotions. In today’s practice, patients’ care is not only confined to the physical ailment but also to the psychological and emotional needs of the patients, hence, the role of emotional intelligence and psychological well-being must be taken seriously, as nurses are confronted not only by the patients’ emotions but also by their own.
 This study aims to gain insight into the level of emotional intelligence and
 psychological well-being among nurses in a psychiatric hospital in Kuwait and to determine the significant relationship between the levels of emotional intelligence, psychological well-being and the profile of mental health nurses focusing on the field of caring. Quantitative non-experimental descriptive correlational design was used, and the standardized questionnaires namely: Schutte Self-Report Emotional Test (SSRET) and Psychological Well-being Scale (PWBS) were used to gather data from 150 respondents. Results shows most of the surveyed respondents are male (58.7%), belongs to generation Y (23 – 38 years old) or the millennial age (65.3%). Mostly are
 married (90%), obtained a baccalaureate degree in nursing (74.7%). Majority are Indian national (66%) having 1 – 5 years of work experience (30%).
 Pearson Product-Moment Correlation and chi square test were used to analyze the data. The results showed a high level of emotional intelligence of mental health nurses’ and low score in almost all the subscale of PWB with a low overall mean score of 141.40 (SD = 20.80). The correlation results also showed that there is no significant positive correlation between emotional intelligence and psychological well-being.
 Further, the result of the chi-squared test showed that there is no statistically
 significant correlation between demographic profile and psychological well-being and emotional intelligence of mental health nurses in Kuwait.

description: We report abundances of elements from $_{26}$Fe to $_{40}$Zr in the cosmic radiation measured by the SuperTIGER (Trans-Iron Galactic Element Recorder) instrument during 55 days of exposure on a long-duration balloon flight over Antarctica. These observations resolve elemental abundances in this charge range with single-element resolution and good statistics. These results support a model of cosmic-ray origin in which the source material consists of a mixture of 19$^{+11}_{-6}$\% material from massive stars and $\sim$81\% normal interstellar medium (ISM) material with solar system abundances. The results also show a preferential acceleration of refractory elements (found in interstellar dust grains) by a factor of $\sim$4 over volatile elements (found in interstellar gas) ordered by atomic mass (A). Both the refractory and volatile elements show a mass-dependent enhancement with similar slopes.

description: We study the possibility of spontaneous symmetry breaking in systems with both charge and dipole symmetries. For $d$-dimensional systems at a positive temperature, we show that charge symmetry cannot be spontaneously broken for $d\leq 4$, while dipole symmetry cannot be spontaneously broken for $d\leq 2$. For $T=0$, we show that charge symmetry cannot be spontaneously broken for $d\leq 2$ if the compressibility is finite. We also show that continuum systems with a dipole symmetry have infinite inertial mass density.

description: Background: voluntary HIV counselling and testing (VCT) is one of the key strategies in the prevention and control of HIV/AIDS in Ethiopia. However, the utilization of VCT service particularly among married couples is very low in Gondar city. We therefore conducted this study to determine the prevalence, willingness and factors associated with VCT service utilization among married couples in Gondar city. Methods: a population based cross sectional study employing both quantitative and qualitative research method was conducted between February and March 2010. A total of 846 married couples aged 18 years and above were sampled from 3 randomly selected kebeles. Data was collected on VCT service utilization and independent variables. Binary logistic regression (bivariate and multivariate analysis) was performed to determine the predictors of VCT service utilization among married couples. Results: 838 married couples (1676 individuals) participated in the study with a response rate of 99.05 %. VCT use was higher among married women in the age group of 18-30 years and 31-40 years than married men. The major barriers to VCT service utilization among married couples were stigma, discrimination, fear of test results, partner rejection, and fear of marital breakage. However, 76.1% of married couples reported that they had willingness to use VCT. Conclusion: the VCT service utilization among married couples in Gondar city was very low. In order to increase VCT service utilization, there should be particular attention on health education, home based VCT programs, pertinent media programs and community mobilization

description: In this work, electrically and thermally conductive poly (butylene terephthalate) nanocomposites were prepared by in-situ ring-opening polymerization of cyclic butylene terephthalate (CBT) in presence of a tin-based catalyst. One type of graphite nanoplatelets (GNP) and two different grades of reduced graphene oxide (rGO) were used. Furthermore, high temperature annealing treatment under vacuum at 1700°C was carried out on both RGO to reduce their defectiveness and study the correlation between the electrical/thermal properties of the nanocomposites and the nanoflakes structure/defectiveness. The morphology and quality of the nanomaterials were investigated by means of electron microscopy, x-ray photoelectron spectroscopy, thermogravimetry and Raman spectroscopy. Thermal, mechanical and electrical properties of the nanocomposites were investigated by means of rheology, dynamic mechanical thermal analysis, volumetric resistivity and thermal conductivity measurements. Physical properties of nanocomposites were correlated with the structure and defectiveness of nanoflakes, evidencing a strong dependence of properties on nanoflakes structure and defectiveness. In particular, a significant enhancement of both thermal and electrical conductivities was demonstrated upon the reduction of nanoflakes defectiveness.

description: Recent MHD simulations find that the reversal of the local resistive interchange parameter $D_R$ from negative to positive due to impurity radiation cooling is able to trigger the resistive tearing mode growth in a tokamak above a threshold in impurity level. A layer of perturbed Pfirsch-Schlüter current density and resistivity are also induced by the impurity radiation, which further govern the tearing mode growth and saturation in the nonlinear stage. The impurity threshold and the tearing mode growth strongly depend on the parallel thermal conductivity, and such a dependence derives from the impact on $D_R$ of the fast parallel thermal equilibration along the helical magnetic field lines.

description: Spontaneous parametric down-conversion (SPDC) is a widely used source for photonic entanglement. Years of focused research have led to a solid understanding of the process, but a cohesive analytical description of the paraxial biphoton state has yet to be achieved. We derive a general expression for the spatio-temporal biphoton state that applies universally across common experimental settings and correctly describes the non-separability of spatial and spectral modes. We formulate a criterion on how to decrease the coupling of the spatial from the spectral degree of freedom by taking into account the Gouy phase of interacting beams. This work provides new insights into the role of the Gouy phase in SPDC, and also into the preparation of engineered entangled states for multidimensional quantum information processing.

description: Background: Currently the prevalence of obesity and overweight increase worldwide and adolescent are one of the vulnerable group to be affected. Reduced physical activity and sedentary behavior including screen time have given attention as a potential risk for high prevalence of overweight/obesity. But in spite of this fact there is little information on the association between screen time and increase overweight/obesity in our setting Objective: The study aimed at determining prevalence of time spent on screen above the recommendation and its relationship with overweight/obesity among secondary school adolescents in Addis Ababa, Ethiopia, in 2018. Method: School based cross sectional study was conducted among adolescent in Addis Ababa, Ethiopia. Sample size was calculated using single population proportion formula and final sample size become 550. Data were collected by using interviewer administered questionnaires. Finally, Descriptive statistics, bivariate analysis and multivariable logistic regression analyses was performed by using SPSS software version 20 and P-value less than 0.05 was used to declare statistically significant association. Result The study found that the mean screen time in the study population was 4.1±2.2 hr. per a day. In which 290 (53.7%) of adolescents spent more than 2hr. on screen. And the prevalence of overweight and obesity were 12.3% and 1.85% respectively. Female sex AOR 1.90 (1.05-3.43), high socio-economic status AOR 2.86 (1.06-7.73), high screen time AOR 3.01 (1.53-5.90), eating habit while watching TV AOR 4.05 (1.83-9.03), physical activity AOR 0.27 (0.13-0.59) were found to have significant association with overweight/obesity. Conclusion and recommendation This study demonstrated a 53.7% prevalence of screen time above recommended amount and also a positive association between longer periods of screen time and overweight/obesity among adolescents in Addis Ababa. Therefore Parents and adolescents should be aware about this association and should be encourage to participate their children in other means of recreational activity.

description: Filaments and sheets are striking visual patterns in cosmic web. The maximum extent of these large-scale structures are difficult to determine due to their structural variety and complexity. We construct a volume-limited sample of galaxies in a cubic region from the SDSS, divide it into smaller subcubes and shuffle them around. We quantify the average filamentarity and planarity in the three-dimensional galaxy distribution as a function of the density threshold and compare them with those from the shuffled realizations of the original data. The analysis is repeated for different shuffling lengths by varying the size of the subcubes. The average filamentarity and planarity in the shuffled data show a significant reduction when the shuffling scales are smaller than the maximum size of the genuine filaments and sheets. We observe a statistically significant reduction in these statistical measures even at a shuffling scale of $\sim 130 \,$Mpc, indicating that the filaments and sheets in three dimensions can extend up to this length scale. They may extend to somewhat larger length scales that are missed by our analysis due to the limited size of the SDSS data cube. We expect to determine these length scales by applying this method to deeper and larger surveys in future.

description: The doubly special relativity (DSR) theories are investigated in order to take into account an observer-independent length scale in special relativity framework. It is widely believed that any quantum theory of gravity would reduce to a DSR model at the flat limit when purely gravitational and quantum mechanical effects are negligible. Gravity's rainbow is a simple generalization of DSR theories to incorporate gravity. In this paper, we show that the effective Friedmann equations that are suggested by loop quantum cosmology (LQC) can be exactly reobtained in rainbow cosmology setup. The deformed geometry of LQC then completely fixes the modified dispersion relation and results in unique DSR model. In comparison with standard LQC scenario where only the geometry is modified, both of the geometry and matter parts get modifications in our setup. In this respect, we find that the total number of microstates for the universe is finite which suggests the statistical origin for the energy and entropy density bounds. These results explicitly show that the DSR theories are appropriate candidates for the flat limit of loop quantum gravity.

A distinct change from a compact nucleus to a nuclear molecule is described as a second order QPT occurring at a certain value of angular momentum. This finding is in accordance with experimental observations when nuclear molecules appear. The method has implication in the fission of heavy nuclei.

description: We present the first three-dimensional gas-dynamical simulations of the grazing envelope evolution (GEE) of stars, with the goal of exploring the basic flow properties and the role of jets at the onset of the GEE. In the simulated runs, a secondary main-sequence star grazes the envelope of the primary asymptotic giant branch (AGB) star. The orbit is circular at the radius of the AGB primary star on its equator. We inject two opposite jets perpendicular to the equatorial plane from the location of the secondary star, and follow the evolution for several orbital periods. We explore the flow pattern by which the jets eject the outskirts of the AGB envelope. After one orbit the jets start to interact with gas ejected in previous orbits and inflate hot low-density bubbles.

description: We find $n(n-3)/2$-dimensional regions of the space of kinematic invariants, where all the solutions to the scattering equations (the core of the CHY formulation of amplitudes) for $n$ massless particles are real. On these regions, the scattering equations are equivalent to the problem of finding stationary points of $n-3$ mutually repelling particles on a finite real interval with appropriate boundary conditions. This identification directly implies that for each of the $(n-3)!$ possible orderings of the $n-3$ particles on the interval, there exists one stable stationary point. Furthermore, restricting to four dimensions, we find that the separation of the solutions into $k\in \{2,3,\ldots ,n-2\}$ sectors naturally matches that of permutations of $n-3$ labels into those with $k-2$ descents. This leads to a physical realization of the combinatorial meaning of the Eulerian numbers.

description: We study general collisions between chiral solitons in Bose-Einstein condensates subject to combined attractive and current-dependent interatomic interactions. A simple analysis based on the linear superposition of the solitons allows us to determine the relevant time and space scales of the dynamics, which is illustrated by extensive numerical simulations. By varying the differential amplitude, the relative phase, the average velocity, and the relative velocity of the solitons, we characterize the different dynamical regimes that give rise to oscillatory and interference phenomena. Apart from the known inelastic character of the collisions, we show that the chiral dynamics involves an amplitude reduction with respect to the case of regular solitons. To compare with feasible ultracold gas experiments, the influence of harmonic confinement is analyzed in both the emergence and the interaction of chiral solitons.

description: DARTWARS (Detector Array Readout with Traveling Wave AmplifieRS) is a three years project that aims to develop high-performing innovative Traveling Wave Parametric Amplifiers (TWPAs) for low temperature detectors and qubit readout (C-band). The practical development follows two different promising approaches, one based on the Josephson junctions (TWJPA) and the other one based on the kinetic inductance of a high-resistivity superconductor (KITWPA). This paper presents the advancements made by the DARTWARS collaboration to produce a first working prototype of a KITWPA.

Factors Affecting Health Extension Workers motivation in selected rural districts of Ethiopia
Creators: name: Tesfaye, Chala
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background: The Health Extension Program (HEP) in Ethiopia is a core component of the broader health system and is one of the strategies implemented with a view to achieving universal coverage of primary health care to the rural population within the context of limited resources. There is scanty evidence on factors influencing motivation of health extension workers (HEWs) in Ethiopia. This study aimed to explore factors affecting motivation of rural HEWs. Methods: A qualitative case study design was used. In depth interview data collection methods carried out for comprehensive understanding of factors affecting motivation among rural HEWs. HEWs working in rural areas are the primary study population. Two districts were selected from Oromia and SNNPR based on accessibility to carry out the research. Sixteen study respondents (no refusal) were sampled considering a wide range of variation in multiple aspects of HEWs like service year, marital status and career level (level III and level IV). The principal investigator collected all data. All interviews were recorded, transcribed, translated, coded and thematically analyzed based on similarities, differences, and associations. Atlas.ti (v 7.5.7) was used to analyze the data. Quality assurance of the study was considered from selection of study design to data analysis and report writing. Result: Factors affecting motivation HEWs were identified at the individual, family, community, and organizational/system levels. Love of work and pride to serve community is personal level motivators. However, workload and burnout were among de-motivating factors at individual level. Moral and domestic work supports are main family level source of HEWs' motivation. At community level, increased respect, acceptance and task sharing motivated HEWs. On the contrary, less acceptability of health service by the community de-motivated HEWs. Slow progress in career advancement; poor supervision, support and governance from leaders, inadequate material availability, no transfer policy, insufficient financial earning were labeled as de-motivating factor at health system/organizational level. Among the motivating factors at organizational level, regular supportive supervision by health center, availability of supplies and on the job trainings were identified. Conclusions: Workload, remuneration, career advancement, transfer policy and leadership support require more attention. Functional linkage with health center, regular training and community engagement are essential to maintain level of motivation.

description: Spatio-temporal complexity of ecological dynamics has been a major focus of research for a few decades. Pattern formation, chaos, regime shifts and long transients are frequently observed in field data but specific factors and mechanisms responsible for the complex dynamics often remain obscure. An elementary building block of ecological population dynamics is a prey-predator system. In spite of its apparent simplicity, it has been demonstrated that a considerable part of ecological dynamical complexity may originate in this elementary system. A considerable progress in understanding of the prey-predator system's potential complexity has been made over the last few years; however, there are yet many questions remaining. In this paper, we focus on the effect of intraspecific competition in the predator population. In mathematical terms, such competition can be described by an additional quadratic term in the equation for the predator population, hence resulting in the variant of prey-predator system that is often referred to as Bazykin's model. We pay a particular attention to the case (often observed in real population communities) where the inherent prey and predator timescales are significantly different: the property known as a `slow-fast' dynamics. Using an array of analytical methods along with numerical simulations, we provide comprehensive investigation into the spatio-temporal dynamics of this system. In doing that, we apply a novel approach to quantify the system solution by calculating its norm in two different metrics such as $C^0$ and $L^2$. We show that the slow-fast Bazykin's system exhibits a rich spatio-temporal dynamics, including a variety of long exotic transient regimes that can last for hundreds and thousands of generations.
