Thermoviscoelasticity in Kelvin–Voigt Rheology at Large Strains
Creators: name: Mielke, Alexander
name: Roubíček, Tomáš
Publisher: name: Humboldt-Universität zu Berlin
Year: 2020
Subjects: subject: 530 Physik

description: The frame-indifferent thermodynamically-consistent model of thermoviscoelasticity at large strain is formulated in the reference configuration by using the concept of the second-grade nonsimple materials. We focus on physically correct viscous stresses that are frame indifferent under time-dependent rotations. Also elastic stresses are frame indifferent under rotations and respect positivity of the determinant of the deformation gradient. The heat transfer is governed by the Fourier law in the actual deformed configuration, which leads to a nontrivial description when pulled back to the reference configuration. The existence of weak solutions in the quasistatic setting, that is inertial forces are ignored, is shown by time discretization.

description: Grenzflächen spielen eine wichtige Rolle bei der Bildung von Biomaterialien in Organismen, z. B. bei der Skelettbildung oder bei der Bildung von Magnetfeld-Rezeptoren, und haben so Einfluss auf Systeme und Prozesse des täglichen Lebens. Um die Abläufe während dieser Strukturbildungsprozesse zu verstehen, wurden viele Studien an der Flüssig- Gas-Grenzfläche durchgeführt. Dieses System entspricht jedoch nicht dem natürlichen Grenzflächensystem. Im Rahmen dieser Dissertation wurde die Strukturbildung an der Flüssig-Flüssig-Grenzfläche, die eher dem natürlichen System entspricht, mit Synchrotronstrahlung untersucht. Messmethoden waren dabei die Röntgenreflektivität und die Röntgendiffraktion. Das Probensystem bestand aus verschiedenen Metallsalzlösungen unter einer Toluolschicht, in der Fettsäuren mit verschiedenen Kettenlängen gelöst waren. Die meisten Metallsalze bildeten Metallseifen mit den im Toluol gelösten Fettsäuren. Die Metallseifen bildeten sich direkt an der Grenzfläche und lagerten sich in einer dünnen Schicht an. Eine Ausnahme stellte Calcium dar. Zwar bildeten sich auch hier Metallseifen, allerdings formten sich hier 50 nm große Kristallite, die sich in einer hoch orientierten Schicht an der Grenzfläche anlagerten. Zudem setzte nach mehreren Tagen eine biomimetische Mineralisation ein.
Sexual Violence among female street Adolescents in Addis Ababa
Creators: name: MoIla, Mitike
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2000

description: A cross-sectional survey among 654 female street adolescents and a qualitative study among 32 male street adolescents were undeltaken to determine the magnitude of rape, attempted rape and its consequences, to describe life skills of escaping the attempt and to describe attitudes of male street ado lescents towards rape in Addis Ababa. The quantitative study revealed that the prevalence of rape among female street adolescents in the last 3 months was 15.6%, (using the definition ofrape as the penile penetration of the vagina), attempted rape 20.4% and unwelcome kiss 16.4%. The most popular way of escaping the attempt was yelling, l'luming, negotiating, and fighting back. Raping a girl in the street as reported by the male focus group study was used as a means of penalizing a girl for adultery or for refusing a sexual advance. The boys report showed that the girls are blamed for their victimization, as "being in the wrong place at the wrong time" and being provocative by talking in a sexual maImer. Rape was significantly associated with living alone and low self-esteem of girls due to early childhood sexual abuse. Unwanted pregnancy, abortion, STDs, and psychological, problems were reported to prevail as consequence of rape. After their victimization 80% of the victims did not report the event to legal bodies. Awareness of street girls towards contraceptive use and STDs were significantly associated with increase in age. This study has showed girls in the street are at a higher ri sk of rape and its consequences. It is recommended that though tackling the root cause i.e., streetism is a long-term issue, establishing a rape crisis center in health institutions with standard STDs treatment and cOlll1seling service, wide spread public education, law protection, training of life skills in protecting girls from rape, night shelter for girls are some of the many to be lIl1dertaken. Fmther more a longitudinal study on the impacts of childhood sexual abuse is recommended. v

description: The purpose of this dissertation is to present the various challenges that medicine has faced in recent years and to highlight the role that health professionals are called upon to undertake regarding medical information via the internet and most specifically regarding the creation of websites that offer health information and services. The role of proper information and medical services on the internet has necessitated the establishment and implementation of codes of conduct for medical websites. This paper examines the quality criteria of health related websites and analyses ethical guidelines that must be adopted by each medical site. These proposals are a combination of existing guidelines, standard criteria and codes of conduct.

description: In our previous papers [arXiv:2106.03150, arXiv:2110.10917, arXiv:2208.00822], we analyzed the asymptotic behavior of future directed null geodesics near future null infinity and then we showed a proposition on the accessibility of the null geodesics to future null infinity in a specific class of asymptotically flat spacetimes. In this paper, we adopt the retarded time of the Bondi coordinate as the parameter for the null geodesics and then see that one can relax the assumptions imposed in our previous studies. As a consequence, we obtain a new null-access theorem for generic asymptotically flat spacetimes.

description: Gel-immobilized colloidal crystals were prepared to obtain hybrid plasmonic-photonic crystals, in which electric field enhancement to a greater extent than that due to localized surface plasmons (LSP) alone was expected due to coupling between LSP and the photonic band. Polystyrene colloidal crystals immobilized by the N-(hydroxymethyl)acrylamide gel were immersed in an aqueous dispersion of gold nanoparticles (AuNPs). Then, the gel-immobilized colloidal crystals were picked out and immersed in an ionic liquid mixture. The surfaces of the gel-immobilized colloidal crystals immersed in the AuNP dispersion were observed via scanning electron microscopy after this solvent substitution. The lattice spacing of the colloidal crystal varied as the composition of the ionic liquid mixture was changed. The composition was determined so that the photonic band gap wavelength coincided with the LSP wavelength. Further, the reflection spectra were measured. Thus, we successfully prepared a hybrid plasmonic-photonic crystal.

description: The linear polarization of thermal dust emission provides a powerful tool to probe interstellar and circumstellar magnetic fields, because aspherical grains tend to align themselves with magnetic field lines. While the Radiative Alignment Torque (RAT) mechanism provides a theoretical framework to this phenomenon, some aspects of this alignment mechanism still need to be quantitatively tested. One such aspect is the possibility that the reference alignment direction changes from the magnetic field ("B-RAT") to the radiation field k-vector ("k-RAT") in areas of strong radiation fields. We investigate this transition toward the Orion Bar PDR, using multi-wavelength SOFIA HAWC+ dust polarization observations. The polarization angle maps show that the radiation field direction is on average not the preferred grain alignment axis. We constrain the grain sizes for which the transition from B-RAT to k-RAT occur in the Orion Bar (grains > 0.1 μm toward the most irradiated locations), and explore the radiatively driven rotational disruption that may take place in the high-radiation environment of the Bar for large grains. While the grains susceptible to rotational disruption should be in supra-thermal rotation and aligned with the magnetic field, k-RAT aligned grains would rotate at thermal velocities. We find that the grain size at which the alignment shifts from B-RAT to k-RAT corresponds to grains too large to survive the rotational disruption. Therefore, we expect a large fraction of grains to be aligned at supra-thermal rotation with the magnetic field, and potentially be subject to rotational disruption depending on their tensile strength.

description: The aim of this paper is to demonstrate the possible use of the new coronal model COCONUT to compute a detailed representation of a numerical CME at 0.1~AU, after its injection at the solar surface and propagation in a realistic solar wind, as derived from observed magnetograms. We present the implementation and propagation of modified Titov-Démoulin (TDm) flux ropes in the COCONUT 3D MHD coronal model. The background solar wind is reconstructed in order to model two opposite configurations representing a solar activity maximum and minimum respectively. Both were derived from magnetograms which were obtained by the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamic Observatory (SDO) satellite. We track the propagation of 24 flux ropes, which differ only by their initial magnetic flux. We especially investigate the geometry of the flux rope during the early stages of the propagation as well as the influence of its initial parameters and solar wind configuration on 1D profiles derived at 0.1~AU. At the beginning of the propagation, the shape of the flux ropes varies between simulations during low and high solar activity. We find dynamics that are consistent with the standard CME model, such as the pinching of the legs and the appearance of post-flare loops. Despite the differences in geometry, the synthetic density and magnetic field time profiles at 0.1~AU are very similar in both solar wind configurations. These profiles are similar to those observed further in the heliosphere and suggest the presence of a magnetic ejecta composed of the initially implemented flux rope and a sheath ahead of it. Finally, we uncover relationships between the properties of the magnetic ejecta, such as density or speed and the initial magnetic flux of our flux ropes.

description: Background: Methods developed to estimate intervention effects in external target populations assume that all important effect measure modifiers have been identified and appropriately modeled. Propensity score-based diagnostics can be used to assess the plausibility of these assumptions for weighting methods. Methods: We demonstrate the use of these diagnostics when assessing the transportability of treatment effects from the standard of care for metastatic colorectal cancer control arm in a phase III trial (HORIZON III) to a target population of 1,942 Medicare beneficiaries age 65+ years. Results: In an unadjusted comparison, control arm participants had lower mortality compared with target population patients treated with the standard of care therapy (trial vs. target hazard ratio [HR] = 0.72, 95% confidence interval [CI], 0.58, 0.89). Applying inverse odds of sampling weights attenuated the trial versus target HR (weighted HR = 0.96, 95% CI = 0.73, 1.26). However, whether unadjusted or weighted, hazards did not appear proportional. At 6 months of follow-up, mortality was lower in the weighted trial population than the target population (weighted trial vs. target risk difference [RD] = -0.07, 95% CI = -0.13, -0.01), but not at 12 months (weighted RD = 0.00, 95% CI = -0.09, 0.09). Conclusion: These diagnostics suggest that direct transport of treatment effects from HORIZON III to the Medicare population is not valid. However, the proposed sampling model might allow valid transport of the treatment effects on longer-term mortality from HORIZON III to the Medicare population treated in clinical practice.

description: Ziel des Forschungsvorhabens ist es, Erkenntnisse zu gewinnen über Lernprozesse von mathematisch schwachen Schülerinnen und Schülern im Umgang mit Variablen in Sachsituationen und diese für die Entwicklung eines Unterrichtsdesigns nutzbar zu machen. Dafür ist es notwendig, den Lerngegenstand zu spezifizieren, ein Unterrichtsdesign zu entwickeln, zu erproben und auszuwerten, sowie daraus resultierend die Theorieentwicklung voranzutreiben. Diese einzelnen Arbeitsbereiche entstammen der fachdidaktischen Entwicklungsforschung, die diesem Projekt seinen Rahmen gibt (Hußmann 2013). Sie sind vielfältig miteinander verknüpft und bauen jeweils aufeinander auf, sodass erst das mehrfache Durchlaufen der Arbeitsbereiche zu vertieften theoretischen Erkenntnissen und praxistauglichen Unterrichtsdesigns führen kann. Dieser Artikel möchte eine erste Annäherung an die Strukturierung des Lerngegenstandes, sowie Entwicklung und Auswertung eines Unterrichtsdesigns vorstellen, die in noch folgenden Forschungszyklen weiter ausdifferenziert und fokussiert werden. Hierauf soll am Ende des Beitrags ein Ausblick gewährt werden.
Risky sexual practices and associated factors among daytime and evening shift of polytechnic college students in Addis Ababa :The case of Nifas silk polytechnic college.
Creators: name: Wale, Wase
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Introduction:Risky sexual behaviors are any practices that increase the probability of adverse sexual and reproductive health.Most college adolescent and young aged 15–24 years are at particularly high risky sexual practices and often characterized by anew-found sense selfgovernment, experimentation with sex and a feeling of invincibility. Objective:To compare the magnitude of risky sexual practices and associated factors among day/regular and evening/extension shift of polytechnic college students in Addis Ababa with the case of Nifassilk polytechnic college. Method and material: A comparative cross sectional study was conducted from March 27April 15, 2019. A stratified sampling technique was used based on type of schooling (day and evening time) and then, allocation of sample was proportionally distributed torespected study levels based on number of students. Study participants were selected using simple random sampling technique. Two population proportion formulas were used to calculate a total sample size of 486 students (243 day/regular and 243 night/extension students). Data was summarized using descriptive statistics including mean, proportion and standard deviation and inferential statistics such as chi-square test and binomial logistic regression. Ethical clearance was obtained from Addis Ababa University School of Public health. Result: A total of 442 students (227 regular/day time and 215 extension/evening shift)participated in the study making the response rate 90.9%. The prevalence of risky sexual practice among regular/day and extension/evening shift students were 34(15%)and 75(34.9%), respectively and the overall prevalence for both type schooling was 109(24.7%). The difference between the two categories is statistically significant (p<0.05). In this study, among those students who had practiced premarital first sexual intercourse, 40(66.6%) and 58(61%) of them had not used condom respectively for day and night time shift students. Conclusion: The study depicted that the prevalence of risky sexual practice among night/evening time students is more than twofold of the prevalence among day time students. The schools and other actors need to address both type of schooling with adolescent and youth friendly risk reduction interventions by giving due emphasis to evening/extension students.

description: Magnetic skyrmions are particle-like textures in the magnetization, characterized by a topological winding number. Nanometer-scale skyrmions have been observed at room temperature in magnetic multilayer structures. The combination of small size, topological quantization, and their efficient electric manipulation makes them interesting candidates for information carriers in high-performance memory devices. A skyrmion racetrack memory has been suggested where information is encoded in the distance between skyrmions moving in a one-dimensional nanostrip. Here, we propose an alternative design where skyrmions move in two (or more) parallel lanes and the information is stored in the lane number of each skyrmion. Such a multilane track can be constructed by controlling the height profile of the nanostrip. Repulsive skyrmion-skyrmion interactions in narrow nanostrips guarantee that skyrmions on different lanes cannot pass each other. Current pulses can be used to induce a lane change. Combining these elements provides a robust, efficient design of skyrmion-based storage devices.

description: Auffassungen von Mathematik sind ein Faktor zur Erklärung der vielzitierten doppelten „Diskontinuität“ im Lehramtsstudium und werden als ein Aspekt der Übergangsproblematik Schule-Hochschule gehandelt. So werden verschiedene hochschuldidaktische Bemühungen im Rahmen der universitären Lehrerbildung u.a. mit dem Ziel begründet, ein „tragfähiges Mathematisches Weltbild“ bei den angehenden Lehrerinnen und Lehrern zu etablieren (vgl. z.B. Beutelspacher u.a., 2011). Dabei ist das Phänomen der „Mathematischen Weltbilder“, „epistemologische Überzeugungen“, „beliefs“ oder des „beliefs systems“ bezüglich der Disziplin Mathematik allgemein aber auch bezüglich des Lehrens und Lernen inzwischen viel beforscht. Eine umfängliche Erforschung der fachimmanenten Auffassungen bezogen auf Teilgebiete der Mathematik insbesondere mit Blick die Besonderheiten der Lehrerbildung steht in des noch aus. Hier setzt ein gemeinsames Forschungsprojekt der Universitäten Köln und Siegen an.

description: In dieser Arbeit wurden besondere Auswirkungen der elektromagnetischen Kopplung auf die Wellenstränge von Turbogeneratoren untersucht. Es wurde nachgewiesen, dass durch asynchron laufende Drehfeldmaschine zusätzliche Stromanteile im Netz entstehen, welche in Synchrongeneratoren zu kritischen Torsionsanregungen im subsynchronen und im supersynchronen Bereich führen können. Es wurde gezeigt, dass bereits sehr kleine Anregungsamplituden ausreichen, um deutliche Torsionsanregungen herbeizuführen. Ferner wurde nachgewiesen, dass durch leistungselektronische Anlagen eine Torsionsanregung und folglich Gefährdung des Wellenstrangs erfolgen kann. In allen Fällen wurde deutlich, dass die Beurteilung einer Gefahr für den Wellenstrang stets einer vielschichtigen Betrachtung bedarf. Auch zeigt sich, dass standarisierte Berechnungsmethoden (z.B. mittels Park’schem Ersatzschaltbild) teilweise an ihre Grenzen stoßen. Schließlich ist die Bedeutung der Torsionsdämpfung nochmals deutlich zu Tage getreten.

description: Στην εργασία αυτή, εξετάζεται κατά το ένα μέρος το υπόδειγμα ή παράδειγμα της νεοφιλελεύθερης σκέψης, όπως το έχουν αναπτύξει οι δύο μεγαλύτεροι θεωρητικοί του: από τη μία ο Φρήντριχ φον Χάγιεκ, εκπρόσωπος της Αυστριακής Σχολής των Οικονομικών και από την άλλη ο Μίλτον Φρίντμαν, καθηγητής οικονομικών του Πανεπιστημίου του Σικάγο. Αυτό συντελείται μέσα από τα βασικότερα έργα τους, που είναι ο «Δρόμος προς τη δουλεία» του Χάγιεκ και το «Καπιταλισμός και ελευθερία» του Φρίντμαν. Επίσης, γίνεται μια περιοδολόγηση στις πολιτικοϊστορικές τους εμπλοκές, εφόσον ο Χάγιεκ συνδέθηκε έντονα με την κυβέρνηση της Μάργκαρετ Θάτσερ ως μέντορας της ίδιας της πρωθυπουργού και ο Φρίντμαν συνδέθηκε έντονα, μεταξύ άλλων, με τη Χιλή του Πινοσέτ. Εν συνεχεία, εξετάζονται οι παράλληλες θέσεις ορισμένων από τους σημαντικότερους Πατέρες της Εκκλησίας, σε βασικές θεματικές όπως η κοινωνικότητα, η (κοινωνική) δικαιοσύνη, και η ελευθερία, η οποία στο νεοφιλελεύθερο υπόδειγμα αφορά την έλλειψη εμποδίων στην δραστηριότητα του επιχειρηματία-κεφαλαιοκράτη. Οι έννοιες αυτές συνάγεται ότι προκύπτουν από διαφορετικής έως και αντιδιαμετρικής σημασίας και μεταξύ τους «σύνθεσης» στα έργα των Πατέρων και στους θεωρητικούς του νεοφιλελεύθερου υποδείγματος
description: In this dissertation, the neoliberal paradigm, as developed by its two greatest theorists, is firstly examined; the thought of Friedrich von Hayek is studied, as of a paramount representative of the Austrian School of Economics, as well as that of Milton Friedman, who was a professor of economics at the University of Chicago, who promoted monetarism. This is carried out through their most fundamental works, which are Hayek's "Road to Serfdom" and Friedman's "Capitalism and Freedom". There is also an examination of their political and historical involvements, since Hayek was strongly associated with Margaret Thatcher's government as Thatcher’s own mentor and Friedman was strongly associated with Pinochet's Chile, among others. Subsequently, the corresponding positions of some of the most important Fathers of the Church are examined, on basic themes and topics such as sociality, (social) justice, and freedom; the latter, when it comes to the neoliberal model, has exclusively got to do with the lack of regulation in the activity of the businessman-capitalist. These concepts are inferred to have a different and even antidiametric meaning and overall "synthesis" in the Patristic works and those of the theorists of the neoliberal paradigm

description: We assemble charged colloidal spheres at deliberately chosen locations on a charged unstructured glass substrate utilizing ion exchange based electro-osmotic micro-pumps. Using microscopy, a simple scaling theory and Brownian Dynamics simulations, we systematically explore the control parameters of crystal assembly and the mechanisms through which they depend on the experimental boundary conditions. We demonstrate that crystal quality depends crucially on the assembly distance of the colloids. This is understood as resulting from the competition between inward transport by the electro-osmotic pump flow and the electro-phoretic outward motion of the colloids. Optimized conditions include substrates of low and colloids of large electro-kinetic mobility. Then a sorting of colloids by size is observed in binary mixtures with larger particles assembling closer to the ion exchanger beads. Moreover, mono-sized colloids form defect free single domain crystals which grow outside a colloid-free void with facetted inner crystal boundaries centred on the ion exchange particle. This works remarkably well, even with irregularly formed ion exchange resin splinters.

description: The generalized parton distributions (GPDs) for the spin-3/2 $Δ^+$ resonance are studied numerically by using a diquark spectator approach. Our results show that symmetric constraints from time reversal on GPDs are satisfied. The axial vector form factors of the system are also provided and compared with the lattice QCD calculation. Furthermore, the structure functions are obtained from GPDs in the forward limit. The evolution of structure functions to the scales up to 4 GeV are carried out as predictions for the possible lattice QCD calculations.

description: The rules that govern spin exchange interaction in pristine graphene nanostructures are constrained by the bipartite character of the lattice, so that the sign of the exchange is determined by whether magnetic moments are on the same sublattice or else. The synthesis of graphene ribbons with perfect zigzag edges and a fluoranthene group with a pentagon ring, a defect that breaks the bipartite nature of the honeycomb lattice, has been recently demonstrated. Here we address how the electronic and spin properties of these structures are modified by such defects, both for indirect exchange interactions as well as the emergent edge magnetism, studied both with DFT and mean field Hubbard model calculations. In all instances we find that the local breakdown of the bipartite nature at the defect reverts the sign of the otherwise ferromagnetic correlations along the edge, introducing a locally antiferromagnetic intra-edge coupling and, for narrow ribbons, also revert the antiferromagnetic inter-edge interactions that are normally found in pristine ribbons. Our findings show that these pentagon defects are a resource that permits to engineer the spin exchange interactions in graphene based nano-structures.

description: We analyze quasi-two-body charmless $B$ decays $B_{(s)} \to P_1 V \to P_1 P_2 P_3$ with $V$ representing a vector resonant, and $P_{1,2,3}$ as a light pseudo-scalar meson, pion, kaon or $η^{(\prime)}$. The intermediate processes $B_{(s)} \to P_1 V $ are calculated in the factorization-assisted topological-amplitude approach and the vector resonant effects are described by the Breit-Wigner propagator, which successively decay to $P_1 P_2$ via strong interaction. Taking into account of all vector resonances in ground state, $ρ, K^*, ω, ϕ$, we present the related branching fractions, and calculate the virtual effects for $B_{(s)} \to π, K (ρ,ω\to) KK$. We also predict direct $\it{CP}$ asymmetries of three body B decay modes with $ρ, K^*$ resonances as intermediate states. Our predicted branching fractions of decay modes dominated by the color-favored tree diagram or the color-favored penguin diagram are consistent with the perturbative QCD approach's predictions as well as QCD factorization approach. While for those nonperturbative contribution dominated decay modes, the branching ratios in this work are in better agreement with current experimental data than the PQCD predictions and the QCD factorization results due to their shortage of the nonperturbative contributions or $1/m_b$ power corrections. Many of the decays channels, especially for direct $\it{CP}$ asymmetries, are waiting for the future experiments.

description: Nanosatellites are becoming more widely used than ever before. Their small form factor and simple manufacturing process makes them the ideal vessel for scientific experiments in space. The AcubeSAT nanosatellite aims to perform high-throughput biological research in space in a low cost, scalable and easily reproducible way. An imaging system to record and analyse scientific data is crucial to this research. However, processes like image capture and compression are complex on embedded systems with limited resources. This thesis will investigate the unique requirements and restrictions of image compression for biological research in space applications. Furthermore, we examine image compression algorithms in space grade embedded systems with limited computational and time resources. The results are compared, and a final compression scheme and techniques are proposed. Lastly, the tools used to achieve the required results are demonstrated

description: Ring-shaped superfluids with weak links provide a perfect environment for studying persistent currents and dynamic stirring protocols. Here, we investigate the effects of a weak-link system on dipolar supersolids. By calculating the ground state energy at fixed angular momenta, we find that metastable persistent currents may exist in the supersolid phase near the superfluid transition point. When stirring the weak link rapidly enough, we show that vortices can enter the supersolid. These vortex entries cause phase slips, emitting solitonic excitations that interfere with the crystalline structure of the supersolid, leading to a continuous melting and recrystallization of the droplets. Finally, we examine the release of vortex-carrying supersolids from the trap, observing that the released density exhibits a discrete structure associated with the density modulation and a central hole resulting from the vortex core.

description: Sexual risk behaviors remained one of the most important tools for assessing the trend of HIV/AIDS epidemic in SSA regions. Further more, they are the major indicators utilized in several evaluative studies for the effectiveness of HIV/AIDS intervention programs, essentially targeting young people. The present study had an objective of assessing the difference in the sexual risk behaviors for HIV infection between out of school anti-AIDS club members and non-member youths in Jimma and Agaro Towns from January to February 2003. Quasi-experimental design in which proportions of major risk behaviors for HIV infection among randomly selected sample of anti-AIDS club member youths of Jimma town compared with a similar sample of non-club member youths in Agaro Town was employed. A pre-tested interviewer administered questionnaire was used to collect data. FGDs were also conducted in the two groups to complement the quantitative findings. The study participants were categorized into four homogenous strata based on their sex and age. Among the study participants, about one third of the club members and a quarter of non-club members admitted to have practiced sexual activity with the mean age at sexual debut of 16.8(61.9) and 16.8(62.1), respectively. Of the sexually active respondents, 30.3% of club members and 16.4% of the non-club members reported to have had two or more non-commercial sexual partners in the last one year, while only 46% and 39.3%, respectively used condom consistently. The differences were not statistically significant in both cases. Club members were found to have better scope of knowledge and attitude and more proportions perceive them themselves to be at risk of VIII HIV infection compared to the non-club members. Both quantitative and qualitative design identified the presence of major misconceptions pertaining to HIV transmission and the role of condom among the non-club member comparison groups. Adolescents and in-school youth were more likely to limit self to a single partner than the older groups. On the other hand alcohol and khat consumption were shown to have a potentiating effect for risky sexual practice. From this study it was concluded that youths organized under anti-AIDS clubs in Jimma town had a better off knowledge, attitude and perception pertaining to HIV/AIDS, while risk practice remained uniform with that of un-intervened group. Thus, more intensified, and comprehensive approach with adequate policy and social support from relevant sectors is highly recommended.

description: Purpose: De-implementation of low-value services among patients with limited life expectancy is challenging. Robust mortality prediction models using routinely collected health care data can enhance health care stakeholders' ability to identify populations with limited life expectancy. We developed and validated a claims-based prediction model for 5-year mortality using regularized regression methods. Methods: Medicare beneficiaries age 66 or older with an office visit and at least 12 months of pre-visit continuous Medicare A/B enrollment were identified in 2008. Five-year mortality was assessed through 2013. Secondary outcomes included 30-, 90-, and 180-day and 1-year mortality. Claims-based predictors, including comorbidities and indicators of disability, frailty, and functional impairment, were selected using regularized logistic regression, applying the least absolute shrinkage and selection operator (LASSO) in a random 80% training sample. Model performance was assessed and compared with the Gagne comorbidity score in the 20% validation sample. Results: Overall, 183 204 (24%) individuals died. In addition to demographics, 161 indicators of comorbidity and function were included in the final model. In the validation sample, the c-statistic was 0.825 (0.823-0.828). Median-predicted probability of 5-year mortality was 14%; almost 4% of the cohort had a predicted probability greater than 80%. Compared with the Gagne score, the LASSO model led to improved 5-year mortality classification (net reclassification index = 9.9%; integrated discrimination index = 5.2%). Conclusions: Our claims-based model predicting 5-year mortality showed excellent discrimination and calibration, similar to the Gagne score model, but resulted in improved mortality classification. Regularized regression is a feasible approach for developing prediction tools that could enhance health care research and evaluation of care quality.

description: This paper presents an innovative neural network model, integrating Convolutional NeuralNetworks (CNN) and Long Short-Term Memory networks (LSTM), designed to longitudinally monitorand predict the health status of elderly individuals living alone. In the model architecture, CNN is taskedwith extracting spatiotemporal features related to behavioral patterns and health from daily activitytrajectory maps, while LSTM leverages these feature sequences to learn the normal behavioral patterns ofthe elderly, handling long-term dependencies in time-series data. This dual approach not only enables theidentification of immediate anomalies but also forecasts potential health issues, such as Alzheimer'sdisease. By defining exceptional behavior tags and encoding them as supervised learning objectives, themodel achieves effective prediction of abnormal states among the elderly, providing a morecomprehensive and proactive solution for their healthcare monitoring.

description: Observations of the cosmic 21-cm power spectrum (PS) are starting to enable precision Bayesian inference of galaxy properties and physical cosmology, during the first billion years of our Universe. Here we investigate the impact of common approximations about the likelihood used in such inferences, including: (i) assuming a Gaussian functional form; (ii) estimating the mean from a single realization; and (iii) estimating the (co)variance at a single point in parameter space. We compare "classical" inference that uses an explicit likelihood with simulation based inference (SBI) that estimates the likelihood from a training set. Our forward-models include: (i) realizations of the cosmic 21-cm signal computed with 21cmFAST by varying UV and X-ray galaxy parameters together with the initial conditions; (ii) realizations of the telescope noise corresponding to a 1000 h integration with SKA1-Low; (iii) the excision of Fourier modes corresponding to a foreground-dominated, horizon "wedge". We find that the 1D PS likelihood is well described by a Gaussian accounting for covariances between wavemodes and redshift bins (higher order correlations are small). However, common approaches of estimating the forward-modeled mean and (co)variance from a random realization or at a single point in parameter space result in biased and over-constrained posteriors. Our best results come from using SBI to fit a non-Gaussian likelihood with a Gaussian mixture neural density estimator. Such SBI can be performed with up to an order of magnitude fewer simulations than classical, explicit likelihood inference. Thus SBI provides accurate posteriors at a comparably low computational cost.
