description: We consider the $1/N$-expansion of the moments of the proper delay times for a ballistic chaotic cavity supporting $N$ scattering channels. In the random matrix approach, these moments correspond to traces of negative powers of Wishart matrices. For systems with and without broken time reversal symmetry (Dyson indices $β=1$ and $β=2$) we obtain a recursion relation, which efficiently generates the coefficients of the $1/N$-expansion of the moments. The integrality of these coefficients and their possible diagrammatic interpretation is discussed.

description: The availability of Martian atmospheric data provided by several Martian missions broadened the opportunity to investigate and study the conditions of the Martian ionosphere. As such, ionospheric models play a crucial part in improving our understanding of ionospheric behavior in response to different spatial, temporal, and space weather conditions. This work represents an initial attempt to construct an electron density prediction model of the Martian ionosphere using machine learning. The model targets the ionosphere at solar zenith ranging from 70 to 90 degrees, and as such only utilizes observations from the Mars Global Surveyor mission. The performance of different machine learning methods was compared in terms of root mean square error, coefficient of determination, and mean absolute error. The bagged regression trees method performed best out of all the evaluated methods. Furthermore, the optimized bagged regression trees model outperformed other Martian ionosphere models from the literature (MIRI and NeMars) in finding the peak electron density value, and the peak density height in terms of root-mean-square error and mean absolute error.

Contribution of the first galaxies to the cosmic far-infrared/sub-millimeter background - I. Mean background level

description: We study the contribution of the first galaxies to the far-infrared/sub-millimeter (FIR/sub-mm) extragalactic background light (EBL) by implementing an analytical model for dust emission. We explore different dust models, assuming different grain size distributions and chemical compositions. According to our findings, observed re-radiated emission from dust in dwarf-size galaxies at $z \sim 10$ would peak at a wavelength of $\sim 500 μ{\rm m}$ with observed fluxes of $\sim 10^{-3} - 10^{-2}$ nJy, which is below the capabilities of current observatories. In order to be detectable, model sources at these high redshifts should exhibit luminosities of $\gtrsim 10^{12} L_{\odot}$, comparable to that of local ultra-luminous systems. The FIR/sub-mm EBL generated by primeval galaxies peaks at $\sim 500 μ{\rm m}$, with an intensity ranging from $\sim 10^{-4}$ to $10^{-3} {\rm nW \ m^{-2} \ sr^{-1}}$, depending on dust properties. These values are $\sim 3 - 4$ orders of magnitude below the absolute measured cosmic background level, suggesting that the first galaxies would not contribute significantly to the observed FIR/sub-mm EBL. Our model EBL exhibits a strong correlation with the dust-to-metal ratio, where we assume a fiducial value of $D = 0.005$, increasing almost proportionally to it. Thus, measurements of the FIR/sub-mm EBL could provide constraints on the amount of dust in the early Universe. Even if the absolute signal from primeval dust emission may be undetectable, it might still be possible to obtain information about it by exploring angular fluctuations at $\sim 500 μ{\rm m}$, close to the peak of dust emission from the first galaxies.

description: School refusal is a costly problem, linked to negative academic, social, and emotional outcomes (Kearney, 2006). However, despite the severity of this problem, youth with medical conditions are often overlooked in school refusal research. This oversight is concerning because youth with medical conditions are overrepresented in school refusal specialty clinics (McShane et al., 2001). Children with medical conditions may be excluded from research because there is no assessment that captures the unique topography of school refusal symptoms in this population. Currently, few methods for assessing school refusal exist and no measure considers the interaction of medical conditions with school refusal symptoms. The aim of this study was to develop a measure which can be used to inform decisions on the function of school refusal behavior in medical populations. I adapted the School Refusal Assessment-Revised (SRA-R), the most researched school refusal instrument, to better capture the experiences of individuals with medical conditions. More specifically, I evaluated the psychometric quality of the adapted SRA-R, referred to as the Pediatric School Refusal Assessment (PSRA), with a sample of 194 caregivers and 88 recently hospitalized patients at Dell Children’s Medical Center. I assessed the factor structure, test-retest reliability, internal consistency, and construct validity of scores on the PSRA caregiver version. Results suggest that the factor structure is acceptable. Additionally, scores on both versions of the PSRA had acceptable test-retest reliability and internal consistency for all factors except pursuit of tangible reinforcement. Due to difficulties recruiting children during the COVID-19 pandemic, for the PSRA child version I only evaluated the internal consistency of its scores and completed an exploratory test-retest reliability analysis. Correlations between the PSRA caregiver version and similar subscales on the Pediatric Quality of Life Inventory and Strengths and Difficulties Questionnaire provide preliminary evidence of scores’ construct validity. These findings provide initial support for the PSRA’s psychometric quality. Further research must address problems with the pursuit of tangible reinforcement factor. Once these issues are addressed, the PSRA may be used to improve the identification and treatment of school refusal in children with medical conditions, which could impact long-term academic, psychological, and social outcome.

description: We study the collapse of an attractive atomic Bose-Einstein condensate prepared in the uniform potential of an optical-box trap. We characterise the critical point for collapse and the collapse dynamics, observing universal behaviour in agreement with theoretical expectations. Most importantly, we observe a clear experimental signature of the counterintuitive weak collapse, namely that making the system more unstable can result in a smaller particle loss. We experimentally determine the scaling laws that govern the weak-collapse atom loss, providing a benchmark for the general theories of nonlinear wave phenomena.

The Use of Students Questionnaire in Identification of Communities at Risk of Onchocerciasis in Kefa, South-West Ethiopia
Creators: name: Argaw, Habtamu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 1993

description: A study was conducted to test the application of the so called "indirect questionnaire approach" using key informants, for the assessment of high risk areas for onchocerciasis. The objective was to determine the validity, cost-effectiveness and operational feasibility of questionnaires. Questionnaires were designed and distributed to six junior high schools via the education officer and administered to 1385 students through their teachers. Validation test was undertaken on 1345 students of the same schools. Using the Spearman rank correlation analysis on the positive response rate on the indictors of onchocerciasis to the parasitological results,all the questions were negatively correlated, due to probably poor perception, immune tolerance and lack of attention to the manifestations in the high risk areas.Report of "nodule" was the only significantly correlated. The use of educational sector was found to be feasible. The indirect questionnaire approach was seven times less expensive, with comparable time and coverage as the biomedical approach. The study area was found to have high prevalence (15.5%) of microfilarial rate in young teenagers, and the endemic area wider. Further study is recommended to assess the applicability of the approach, in different socioeconomic and demographic situations

description: The upcoming Square Kilometer Array (SKA) is expected to produce humongous amount of data for undertaking H{\sc i}~science. We have developed an MPI-based {\sc Python} pipeline to deal with the large data efficiently with the present computational resources. Our pipeline divides such large H{\sc i}~21-cm spectral cubes into several small cubelets, and then processes them in parallel using publicly available H{\sc i}~source finder {\sc SoFiA-$2$}. The pipeline also takes care of sources at the boundaries of the cubelets and also filters out false and redundant detections. By comapring with the true source catalog, we find that the detection efficiency depends on the {\sc SoFiA-$2$} parameters such as the smoothing kernel size, linking length and threshold values. We find the optimal kernel size for all flux bins to be between $3$ to $5$ pixels and $7$ to $15$ pixels, respectively in the spatial and frequency directions. Comparing the recovered source parameters with the original values, we find that the output of {\sc SoFiA-$2$} is highly dependent on kernel sizes and a single choice of kernel is not sufficient for all types of H{\sc i}~galaxies. We also propose use of alternative methods to {\sc SoFiA-$2$} which can be used in our pipeline to find sources more robustly.

description: Measurements of double helicity asymmetries in inclusive hadron production in polarized $p + p$ collisions are sensitive to helicity-dependent parton distribution functions, in particular to the gluon helicity distribution, ∆g. This study focuses on the extraction of the double helicity asymmetry in $\eta$ production ($\vec{p}+\vec{p}$ → $\eta+X$), the $\eta$ cross section and the $\eta/\pi^0$ cross section ratio. The cross section and ratio measurements provide essential input for the extraction of fragmentation functions that are needed to access the helicity-dependent parton distribution functions.

description: Introduction: - The end result of HIV/ AIDS infection is the depletion of the immune system leading to a spectrum of various HIV/ AIDS associated opportunistic infections. Tuberculosis chronic and acute diarrhea of protozoal and bacterial infections, central nervous system infections with toxoplasma Gondi is the leading causes of morbidity and mortality in HIV/ AIDS infected patents. Objective: To describe the prevalence of opportunistic infection among HIV/AIDS patients and to identify socio-demographic factors for the development of severe forms namely central nervous system toxoplasmosis, pneumocysitc carrini pneumonia in the antiretro viral therapy clinics of public hospitals in Addis Ababa. Methods: A cross sectional study design on clinical records of HIV/AIDS patients in ART clinics. Systematic random sampling method was used to obtain the required sample. The total sample size was 566 Result: Oral candidacies 326(58. 0 %), Tuberculosis of all forms 260 (45.9%) and herpes zoster 198 (35%) had the highest prevalence. Therefore the prevalence of sever forms of the opportunistic infections made up 17.7% of the total sample. Using binary logistic regression model, WHO stage IV had an independent association with the distribution of the sever forms of the opportunistic infections. The odds of having the sever forms of the opportunistic infections was 40 times higher in the respondents who were in stage IV condition than stage III or II combined. The distribution of the sever form of opportunistic infections in St. Peter's hospital was lower by 85% as compared to the referent hospital. There was no difference in the distribution of the sever forms of the opportunistic infections in the other 7 hospitals. There was also no difference in the distribution of the sever forms of the opportunistic infections among the socio demographic group of the age, sex, marital status and education. Conclusion: Oral candidacies, TB of all forms and herpes zoster were the predominant OIS. Only WHO stage IV condition and patients from St. Peters hospital were associated with the distribution of sever forms of the OIs. Recommendation: Skilled professionals for the management of the OIs and the implementation of the TB and HIV collaborative activities are of critical importance. VIII

description: We theoretically and numerically investigate spin waves that occur in systems of classical magnetic dipoles that are arranged at the vertices of a regular polygon and interact solely via their magnetic fields. There are certain limiting cases that can be analyzed in detail. One case is that of spin waves as infinitesimal excitations from the system's ground state, where the dispersion relation can be determined analytically. The frequencies of these infinitesimal spin waves are compared with the peaks of the Fourier transform of the thermal expectation value of the autocorrelation function calculated by Monte Carlo simulations. In the special case of vanishing wave number an exact solution of the equations of motion is possible describing synchronized oscillations with finite amplitudes. Finally, the limiting case of a dipole chain with $N\longrightarrow \infty$ is investigated and completely solved.

description: Gaia19fct is one of the Gaia-alerted eruptive young stars that has undergone several brightening events. We conducted monitoring observations using multi-filter optical and near-infrared photometry, as well as near-infrared spectroscopy, to understand the physical properties of Gaia19fct and investigate whether it fits into the historically defined two classes. We present the analyses of light curves, color variations, spectral lines, and CO modeling. The light curves show at least five brightening events since 2015, and the multi-filter color evolutions are mostly gray. The gray evolution indicates that bursts are triggered by mechanisms other than extinction. Our near-infrared spectra exhibit both absorption and emission lines and show time-variability throughout our observations. We found lower rotational velocity and lower temperature from the near-infrared atomic absorption lines than from the optical lines, suggesting that Gaia19fct has a Keplerian rotating disk. The CO overtone features show a superposition of absorption and emission components, which is unlike other young stellar objects. We modeled the CO lines, and the result suggests that the emission and absorption components are formed in different regions. We found that although Gaia19fct exhibits characteristics of both types of eruptive young stars, FU Orionis-type objects (FUors) and EX Lupi-type objects (EXors), it shows more similarity with EXors in general.

description: The persistence of planetary systems after their host stars evolve into their post-main sequence phase is poorly constrained by observations. Many young white dwarf systems exhibit infrared excess emission and/or spectral absorption lines associated with a reservoir of dust (or planetesimals) and its accretion. However, most white dwarfs are too cool to sufficiently heat any circumstellar dust to detectable levels of emission. The Helix Nebula (NGC 7293) is a young, nearby planetary nebula; observations at mid- and far-infrared wavelengths revealed excess emission associated with its central white dwarf (WD 2226-210). The origin of this excess is ambiguous. It could be a remnant planetesimal belt, a cloud of comets, or the remnants of material shed during the post-asymptotic giant branch phase. Here we combine infrared (SOFIA, Spitzer, Herschel ) and millimetre (ALMA) observations of the system to determine the origin of this excess using multi-wavelength imaging and radiative transfer modelling. We find the data are incompatible with a compact remnant planetesimal belt or post-asymptotic giant branch disc, and conclude the dust most likely originates from deposition by a cometary cloud. The measured dust mass, and lifetime of the constituent grains, implies disruption of several thousand Hale-Bopp equivalent comets per year to fuel the observed excess emission around the Helix Nebula's white dwarf.

Parallel Priority-Flood Depression Filling For Trillion Cell Digital Elevation Models On Desktops Or Clusters

description: Algorithms for extracting hydrologic features and properties from digital elevation models (DEMs) are challenged by large datasets, which often cannot fit within a computer's RAM. Depression filling is an important preconditioning step to many of these algorithms. Here, I present a new, linearly-scaling algorithm which parallelizes the Priority-Flood depression-filling algorithm by subdividing a DEM into tiles. Using a single-producer, multi-consumer design, the new algorithm works equally well on one core, multiple cores, or multiple machines and can take advantage of large memories or cope with small ones. Unlike previous algorithms, the new algorithm guarantees a fixed number of memory access and communication events per subdivision of the DEM. In comparison testing, this results in the new algorithm running generally faster while using fewer resources than previous algorithms. For moderately sized tiles, the algorithm exhibits ~60% strong and weak scaling efficiencies up to 48 cores, and linear time scaling across datasets ranging over three orders of magnitude. The largest dataset on which I run the algorithm has 2 trillion (2*10^12) cells. With 48 cores, processing required 4.8 hours wall-time (9.3 compute-days). This test is three orders of magnitude larger than any previously performed in the literature. Complete, well-commented source code and correctness tests are available for download from a repository.

description: Unconventional Weyl phonons with higher topological charges in crystalline solids have attracted increasing attention. By symmetry analysis and low-energy $k.p$ effective Hamiltonian, we propose the symmetry enforced triple hourglass Weyl phonons (THWPs) with Chern number $\mathcal C$ = $\pm$ 3 protected by $6_3$ screw rotation symmetry in chiral space groups 173 ($P6_3$) and 182 ($P6_322$). We take LiIO$_3$ with space group 173 as a candidate and confirm that it possesses THWP with linear and quadratic dispersions along the $k_z$ direction and in the $k_x$-$k_y$ plane, respectively. Due to the constraints of crystal symmetry and topological charge conservation, six equivalent single Weyl phonons (SWPs) emerge and lie in the $k_z$ = 0 plane. Therefore, the unique phonon surface arcs connect the projections of two THWPs and six SWPs, leading to nontrivial sextuple-helicoid surface arcs on the (001) surface Brillouin zone. Our work proposes a class of topological phonons and realizes it in realistic materials, providing a perfect platform for experimental observation of THWPs. We expect our work to provide a new idea for detection of unconventional quasiparticles.

description: G4.8+6.2 was proposed as a possible kilonova remnant associated with the Korean guest star of AD 1163 in our Milky Way galaxy. Its age is about 860 years according to the historical record. If a neutron star was left in the center of G4.8+6.2, this young neutron star may radiate strong continuous gravitational waves, which could beat the indirect age-based upper limit with current LIGO sensitivity. In this work, we searched such continuous gravitational waves in the frequency band $20-1500 \mathrm{~Hz}$. This search used two days of LIGO O3b data from the Hanford and Livingston detectors. While no signal was found, we placed upper limits on the gravitational wave strain. For comparison, we also showed the latest results of all-sky searches obtained with various search pipelines. With upgrading of the gravitational wave detectors, it will provide the opportunity to see whether a black hole or a neutron star is harbored inside G4.8+6.2.

description: Fortunately most young people are not infected with HIV/AIDS. Infact during early adolescents HIV rate are the lowest of any period during the life cycle. The challenge is to keep them this way .Yet, it is also young people who often beers the greatest hope of changing the course of HIV/AIDS epidemic if they are given the tools and support to do so. In Ethiopia information on the knowledge and attitude about HIV/AIDS and related issue among this early adolescents is scanty. This study aimed to asses the knowledge of HIV/AIDS and factors that influence students knowledge and attitude. A cross-sectional study using self-administered questionnaire was carried out among randomly selected students in five general primary schools in Kombolcha town South Wello Zone of Amhara Regional State during November 2004 to January 2005. A total of 600 students (309 male and 291 female) 10 to 14 years old attending grade 5 to 8 were enrolled in the study. Four hundred and thirty seven (73 %), and 404 (67 %) of the respondents were knowledgeable about HIV/AIDS mode of transmission and prevention methods respectively and 98(16.3%) of them had also comprehensive knowledge on HIV/AIDS. About 430(72 %) of them had positive attitude towards AIDS patient, AIDS orphan and PLWHA. Four hundred and ten (68.3%) and 450(75.8%) replied that they discussed about HIV/AIDS with their parents and peers, respectively. Only 41 (6.1%) of the students perceived their susceptibility to HIV/AIDS. Students in higher grade level, Christians, those who discussed with their peers, and who got information from mass media source [OR=2.69(1.59,4.55), [OR=2.12(1.23,3.63)], [OR=1.88(1.11,3.19)] and [OR=1.75(1.10,2.79)] respectively had significant association with mode of transmission knowledge. Similarly respondents in higher grade level, Christians, and who got information from mass media source [OR=1.60(1.02,2.52)], [OR=2.02(1.01,3.39)] and [OR=1.76(1.12,2.75)] respectively had significant association with prevention method knowledge. Being old age [OR=2.01(1.22,3.29), urban residence [OR=1.92(1.10,3.35), Christians affiliation VIII [OR=3.39(2.07,5.54)], those from medium [OR=5.42(2.49,11.80)] and low [OR=3.37(1.66,6.84)] perceived family economic status respectively and mass media source of information [OR=1.57=(1.01,2.44)] had significant association with Students positive attitude. It was also concluded that students knowledge on the mode of transmission and prevention method were moderate and majority of participants did not show discriminatory and stigmatized attitude. Strengthening the current HIV/AIDS education going on in the school, sustaining the non-discriminatory attitude through strengthening the on going message are recommended. Key words: Early adolescents, HIV/AIDS, transmission, prevention, attitude, perceived susceptibility, Kombolcha, South Wello, Amhara and Ethiopia.

description: In the field of high-order harmonic generation from solids, the electron motion typically exceeds the edge of the first Brillouin zone. In conventional nonlinear optics, on the other hand, the excursion of band electrons is negligible. Here, the transition from conventional nonlinear optics to the regime where the crystal electrons begin to explore the first Brillouin zone is investigated. It is found that the nonlinear optical response changes abruptly already before intraband currents due to ionization become dominant. This is observed by an interference structure in the third-order harmonic generation of few-cycle pulses in a non-collinear geometry. Although approaching Keldysh parameter $γ= 1$, this is not a strong-field effect in the original sense, because the iterative series still converges and reproduces the interference structure. The change of the nonlinear interband response is attributed to Bloch motion of the reversible (or transient or virtual) population, similar to the Bloch motion of the irreversible (or real) population which affects the intraband currents that have been observed in high-order harmonic generation.

description: Using direct numerical simulations of three-dimensional magnetohydrodynamic (MHD) turbulence the spatio-temporal behavior of magnetic field fluctuations is analyzed. Cases with relatively small, medium and large values of a mean background magnetic field are considered. The (wavenumber) scale dependent time correlation function is directly computed for different simulations, varying the mean magnetic field value. From this correlation function the time decorrelation is computed and compared with different theoretical times, namely, the local non-linear time, the random sweeping time, and the Alfvénic time, the latter being a wave effect. It is observed that time decorrelations are dominated by sweeping effects, and only at large values of the mean magnetic field and for wave vectors mainly aligned with this field time decorrelations are controlled by Alfvénic effects.

description: Reconstruction of the tridimensional geometry of a visual scene using the binocular disparity information is an important issue in computer vision and mobile robotics, which can be formulated as a Bayesian inference problem. However, computation of the full disparity distribution with an advanced Bayesian model is usually an intractable problem, and proves computationally challenging even with a simple model. In this paper, we show how probabilistic hardware using distributed memory and alternate representation of data as stochastic bitstreams can solve that problem with high performance and energy efficiency. We put forward a way to express discrete probability distributions using stochastic data representations and perform Bayesian fusion using those representations, and show how that approach can be applied to diparity computation. We evaluate the system using a simulated stochastic implementation and discuss possible hardware implementations of such architectures and their potential for sensorimotor processing and robotics.

description: Measurements of double helicity asymmetries in inclusive hadron production in polarized $p + p$ collisions are sensitive to helicity-dependent parton distribution functions, in particular to the gluon helicity distribution, ∆g. This study focuses on the extraction of the double helicity asymmetry in $\eta$ production ($\vec{p}+\vec{p}$ → $\eta+X$), the $\eta$ cross section and the $\eta/\pi^0$ cross section ratio. The cross section and ratio measurements provide essential input for the extraction of fragmentation functions that are needed to access the helicity-dependent parton distribution functions.

description: We present observations of the active M-dwarf binary AT Mic (dM4.5e+dM4.5e) obtained with the orbital observatory AstroSat. During 20 ks of observations, in the far ultraviolet ($130-180$ nm) and soft X-ray ($0.3-7$ keV) spectral ranges, we detected both quiescent emission and at least five flares on different components of the binary. The X-ray flares were typically longer than and delayed (by $5-6$ min) with respect to their ultraviolet counterparts, in agreement with the Neupert effect. Using X-ray spectral fits, we have estimated the parameters of the emitting plasma. The results indicate the presence of a hot multi-thermal corona with the average temperatures in the range of $\sim 7-15$ MK and the emission measure of $\sim (2.9-4.5)\times 10^{52}$ $\textrm{cm}^{-3}$; both the temperature and the emission measure increased during the flares. The estimated abundance of heavy elements in the corona of AT Mic is considerably lower than at the Sun ($\sim 0.18-0.34$ of the solar photospheric value); the coronal abundance increased during the flares due to chromospheric evaporation. The detected flares had the energies of $\sim 10^{31}-10^{32}$ erg; the energy-duration relations indicate the presence of magnetic fields stronger than in typical solar flares.

description: Several experimental efforts such as material investigation and structure improvement have been made recently to find a large anomalous Nernst effect in ferromagnetic metals. Here, we develop a theory of spin transport driven by the anomalous Nernst effect in a diffusive ferromagnetic/nonmagnetic multilayer. Starting from a phenomenological formula of a spin-dependent electric current, the theoretical formulas of electric voltage and spin torque generated by the anomalous Nernst effect are derived. The magnitude of the electric voltage generated from the spin current via the inverse spin Hall effect is on the order of $0.1$ $μ$V for currently available experimental parameter values. The temperature gradient necessary to switch the magnetization is quite larger than the typical experimental value. The separation of the contributions of the Seebeck and transverse spin Seebeck effects is also discussed.

description: Fe-B-Si system is a matrix for synthesis of new functional materials with exceptional magnetic and mechanical properties. Progress in this area is associated with the search for optimal doping conditions. This theoretical and experimental study is aimed to address the influence of Ta alloying on the structure of undercooled (Fe0.75B0.15Si0.1)100-xTax (x=0-2) melts, their undercoolability and the processes of structure formation during solidification. Small concentration of Ta complicates standard ab initio and machine learning investigations. We developed a technique for fast and stable training of machine learning interatomic potential (MLIP) in this case and uncovered the structure of the undercooled melts. Molecular dynamic simulations with MLIP showed that at Ta concentration of 1 at.% there is a sharp change in the chemical short-range ordering in the melt associated with a change in the interaction of Ta atoms. This effect leads to a restructuring of the cluster formation in the system. At the same time, our experimental investigation shows that melts with a Ta content of 1 at.% have the greatest tendency to undercoolability. Alloying with Ta promotes the formation of primary crystals of Fe2B, and at a concentration of more than 1.5 at.% Ta, also of FeTaB. Herewith, near 1 at.% Ta, the crystallization of the melt proceeds nontrivially: with the formation of two intermediate metastable phases Fe3B and Fe2Ta Laves phase. Also, the highest tendency to amorphization under conditions of quick quenching is exhibited by a melt with a Ta concentration of 1 at.%. The results not only provide understanding of optimal alloying of Fe-B-Si materials but also promote a machine learning method for numerical design of metallic alloys with a small dopant concentration.
