description: We present an efficient heating/cooling method coupled with chemistry and ultraviolet (UV) radiative transfer, which can be applied to numerical simulations of the interstellar medium (ISM). We follow the time-dependent evolution of hydrogen species (H$_2$, H, H$^+$), assume carbon/oxygen species (C, C$^+$, CO, O, and O$^+$) are in formation-destruction balance given the non-steady hydrogen abundances, and include essential heating/cooling processes needed to capture thermodynamics of all ISM phases. UV radiation from discrete point sources and the diffuse background is followed through adaptive ray tracing and a six-ray approximation, respectively, allowing for H$_2$ self-shielding; cosmic ray (CR) heating and ionization are also included. To validate our methods and demonstrate their application for a range of density, metallicity, and radiation field, we conduct a series of tests, including the equilibrium curves of thermal pressure vs. density, the chemical and thermal structure in photo-dissociation regions, H I-to-H$_2$ transitions, and the expansion of H II regions and radiative supernova remnants. Careful treatment of photochemistry and CR ionization is essential for many aspects of ISM physics, including identifying the thermal pressure at which cold and warm neutral phases co-exist. We caution that many current heating and cooling treatments used in galaxy formation simulations do not reproduce the correct thermal pressure and ionization fraction in the neutral ISM. Our new model is implemented in the MHD code Athena and incorporated in the TIGRESS simulation framework, for use in studying the star-forming ISM in a wide range of environments.

description: Predicting how much mixing occurs when a given amount of energy is injected into a Boussinesq fluid is a longstanding problem in stratified turbulence. The huge number of degrees of freedom involved in those processes renders extremely difficult a deterministic approach to the problem. Here we present a statistical mechanics approach yielding prediction for a cumulative, global mixing efficiency as a function of a global Richardson number and the background buoyancy profile.

Personal dust exposure and chronic respiratory health symptoms among flour mill factory Workers in Akaki kaliti sub city, Addis Ababa, Ethiopia, 2019.
Creators: name: Amare, Embay
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Background: Flour mill workers are at an increased risk of developing respiratory symptoms due to exposure to flour dust in their working environment. Exposure to flour dust linked with the development of chronic respiratory disorders. However, very little evidence has been available on the exposure level of flour dust and the respiratory health status of exposed workers. Objective: The aim of this study was to assess personal dust exposure level, chronic respiratory health symptoms and associated factors among flour mill workers in Addis Ababa, Ethiopia. Methods: Cross-sectional study was conducted among a sample of 424 randomly selected workers from Kaliti and Fafa flour mill factories. Respiratory health symptoms were assessed using an American Thoracic Society standard questionnaire customized with local context. For personal dust exposure assessment a total of 50 personal dust samplers were collected from 25 randomly selected workers. A repeated sample was taken from five work sections having similar exposure group following Rappaport sampling recommendation. Epi-Info V. 7.2 and SPSS V.21 statistical software were used for data entry and analysis, respectively. Descriptive statistics was used, and data was presented using tables and figures. Gravimetric analysis of the filters was done using a standard micro-balance with a detection limit 0.01mg in Environmental and Occupational Health accredited Laboratory, School of Public Health, Addis Ababa University. The dust level was described and compared with the threshold limit value of American conference of governmental industrial hygienist recommendation (10 mg/m3) for total dust. Results: Majority (92%) of workers were exceeded the threshold limit value recommended for total dust (10 mg/m 3 ). The prevalence of chronic respiratory health symptoms among flour mill factory workers was 58.3% (53.7-63.4). Chronic respiratory health symptoms were significantly associated with age group(AOR=1.95, 95%CI;1.17-2.79 and AOR=12.3, 95%CI;4.39-34.6), monthly income (AOR=1.68, 95% CI;1-2.79), work experience (AOR=2.58, 95% CI;1-6.62), past dust exposure (AOR=1.86, 95% CI;1.08-3.2) and utilization of respiratory protective equipment's (AOR=2.29, 95%CI;1.27-4.13).The GM (±GSD) of dust exposure level was 62.75(±12.55) mg/m 3 . Conclusion and recommendation: Chronic respiratory health symptoms were highly prevalent among flour mill factory workers and workers who exposed to flour dust concentration was above the acceptable recommended limit value. Supportive supervision and solution between Ministry of Labour and Social Affairs, flour mill managers and workers is needed to reduce exposure and improve working environment.

description: The PhotoDissociation Region Toolbox provides comprehensive, easy-to-use, public software tools and models that enable an understanding of the interaction of the light of young, luminous, massive stars with the gas and dust in the Milky Way and in other galaxies. It consists of an open-source Python toolkit and photodissociation region models for analysis of infrared and millimeter/submillimeter line and continuum observations obtained by ground-based and sub-orbital telescopes, and astrophysics space missions. Photodissociation regions (PDRs) include all of the neutral gas in the ISM where far-ultraviolet photons dominate the chemistry and/or heating. In regions of massive star formation, PDRs are created at the boundaries between the H II regions and neutral molecular cloud, as photons with energies 6 eV $ < h ν< $ 13.6 eV photodissociate molecules and photoionize metals. The gas is heated by photo-electrons from small grains and large molecules and cools mostly through far-infrared fine-structure lines like [O I] and [C II]. The models are created from state-of-the art PDR codes that includes molecular freeze-out; recent collision, chemical, and photo rates; new chemical pathways, such as for oxygen chemistry; and allow for both clumpy and uniform media. The models predict the emergent intensities of many spectral lines and FIR continuum. The tools find the best-fit models to the observations and provide insights into the physical conditions and chemical makeup of the gas and dust. The PDR Toolbox enables novel analysis of data from telescopes such as ISO, Spitzer, Herschel, STO, SOFIA, SWAS, APEX, ALMA, and JWST.

description: The Cosmology Large Angular Scale Surveyor (CLASS) is a four telescope array designed to characterize relic primordial gravitational waves from inflation and the optical depth to reionization through a measurement of the polarized cosmic microwave background (CMB) on the largest angular scales. The frequencies of the four CLASS telescopes, one at 38 GHz, two at 93 GHz, and one dichroic system at 145/217 GHz, are chosen to avoid spectral regions of high atmospheric emission and span the minimum of the polarized Galactic foregrounds: synchrotron emission at lower frequencies and dust emission at higher frequencies. Low-noise transition edge sensor detectors and a rapid front-end polarization modulator provide a unique combination of high sensitivity, stability, and control of systematics. The CLASS site, at 5200 m in the Chilean Atacama desert, allows for daily mapping of up to 70\% of the sky and enables the characterization of CMB polarization at the largest angular scales. Using this combination of a broad frequency range, large sky coverage, control over systematics, and high sensitivity, CLASS will observe the reionization and recombination peaks of the CMB E- and B-mode power spectra. CLASS will make a cosmic variance limited measurement of the optical depth to reionization and will measure or place upper limits on the tensor-to-scalar ratio, $r$, down to a level of 0.01 (95\% C.L.).

description: The precursors of short and long Gamma Ray Bursts (SGRBs and LGRBs) can serve as probes of their progenitors, as well as shedding light on the physical processes of mergers or core-collapse supernovae. Some models predict the possible existence of Quasi-Periodically Oscillations (QPO) in the precursors of SGRBs. Although many previous studies have performed QPO search in the main emission of SGRBs and LGRBs, so far there was no systematic QPO search in their precursors. In this work, we perform a detailed QPO search in the precursors of SGRBs and LGRBs detected by Fermi/GBM from 2008 to 2019 using the power density spectrum (PDS) in frequency domain and Gaussian processes (GP) in time domain. We do not find any convinced QPO signal with significance above 3 $σ$, possibly due to the low fluxes of precursors. Finally, the PDS continuum properties of both the precursors and main emissions are also studied for the first time, and no significant difference is found in the distributions of the PDS slope for precursors and main emissions in both SGRBs and LGRBs.

A self-consistent theory of localization in nonlinear random media
Creators: name: Cherroret, Nicolas
Publisher: name: arXiv
Year: 2016
Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: The self-consistent theory of localization is generalized to account for a weak quadratic nonlinear potential in the wave equation. For spreading wave packets, the theory predicts the destruction of Anderson localization by the nonlinearity and its replacement by algebraic subdiffusion, while classical diffusion remains unaffected. In 3D, this leads to the emergence of a subdiffusion-diffusion transition in place of the Anderson transition. The accuracy and the limitations of the theory are discussed.

description: In 2019, the Technical University of Chemnitz (TUC) in Germany has started a project to establish a new research Information system providing structured academic information in a Linked Data fashion. In the first analysis phase, essential requirements for the implementation of a rich, sustainable, digital research information system were identified and concretized. Various established research information systems at other institutions were evaluated and compared; deciding for Duraspace’s VIVO in the end. In the initial development period, we achieved the first milestone to deploy, customize, and populate a stable demonstrator with basic functionalities. At the moment, we face three particular challenges related to the complexity of data, data ingestion, and technical issues that we want to share and discuss in our talk. Besides traditional VIVO information entity types, we provide additional information on academic projects, publications, and the knowledge skills of a researcher or professorship. The main challenge is to gather and provide meta-information about an entity, which cannot directly be taken from an existing data source. An example of that is the wish to apply VIVO as an expert search application where expertise information is provided for every researcher. The next challenge is the decision to which extent are staff members allowed to update automatically-collected information. In particular, by using the existing VIVO backend interface and how to ensure to not overwrite updated information in the next ingestion activity. Finally, the RIS needs to include different landing pages and focal points in views for stakeholders from the university, industry, the media sector, and other social areas. We would like to share our own VIVO experience, our future development plan as well as listen to the feedback from the VIVO community.
The association Between Substance Abuse and HIV infection among People Visiting HIV Testing and Counseling centers in Addis Ababa, Ethiopia

description: The magnitude of HIV/AIDS in Ethiopia is ever increasing. It is also believed that the use of substances is increasing in some major towns including Addis Ababa. However, data regarding the relation of substance abuse and HIV infection is lacking. A case-control study was carried out in Addis Ababa from December 2001 to February 2002 to explore the association between substance abuse and HIV infection and to determine the prevalence and the factors related to substance abuse among people visiting HIV testing and counseling centers. Among all visitors for HIV testing and counseling, 227 cases and 726 controls were identified. Cases and controls were compared by socio demographic, socio economic, exposure to substances and risky behaviors that predispose them to HIV infection. The prevalence of "hard' drug use was found to be 1.2% with the rate being 3.2% in the cases and 0.54% in the controls. Alcohol drinking was found to be associated with serum HIV positivity after controlling for other confounding variables. While young age of 15 to 24 and being single were found to be associated with serum HIV positivity, having monthly family income was found to be protective against HIV infection. Being male and having sex with commercial sex workers were related to both alcohol drinking and khat chewing. From the study, we concluded high prevalence of alcohol and khat abuse among people visiting HIV counseling and testing centers. Alcohol was found to be a significant risk factor for HIV infection among people visiting HIV testing and counseling centers. The need of health education to bring behavioral changes and further study to identify the prevalence and role of substance in exposure to HIV infection in the community is recommended.
The Host Galaxies of Hybrid Morphology Radio Sources

description: Based on their differing radio morphologies, powerful radio galaxies can be separated into the Fanaroff-Riley I (FR-I) and II (FR-II) classes. Hybrid morphology radio sources (HyMoRS) contain morphologies consistent with each type of jet on either side: a powerful, highly relativistic FR-II-like jet terminating in a hotspot on one side and an FRI-like plume on the other. HyMoRS present a unique opportunity to study the conditions which give rise to the dichotomy. Using host galaxy properties, we conduct the first multiwavelength investigation into whether orientation can explain HyMoRS morphology. Through optical spectroscopy and mid-infrared photometry, we analyze the emission characteristics, and evaluate the broad characteristics of five HyMoRS host galaxies at intermediate redshifts (0.4 < z < 1.5). The HyMoRS host galaxies in our sample have properties consistent with typical host galaxies of FR-II sources, suggesting that the observed hybrid morphologies may be caused by a dense, cluster-like environment bending FR-II jets combined with a favorable orientation which can make one side appear similar to an FR-I jet. Our results thus support the hypothesis that HyMoRS are mainly caused by environment and orientation.

description: We present the mathematical analysis of generalized complex contagions in clustered multiplex networks for susceptible-infected-recovered (SIR)-like dynamics. The model is intended to understand diffusion of influence, or any other spreading process implying a threshold dynamics, in setups of interconnected networks with significant clustering. The contagion is assumed to be general enough to account for a content-dependent linear threshold model, where each link type has a different weight (for spreading influence) that may depend on the content (e.g., product, rumor, political view) that is being spread. Using the generating functions formalism, we determine the conditions, probability, and expected size of the emergent global cascades. This analysis provides a generalization of previous approaches and is specially useful in problems related to spreading and percolation. The results present non trivial dependencies between the clustering coefficient of the networks and its average degree. In particular, several phase transitions are shown to occur depending on these descriptors. Generally speaking, our findings reveal that increasing clustering decreases the probability of having global cascades and their size, however this tendency changes with the average degree. There exists a certain average degree from which on clustering favours the probability and size of the contagion. By comparing the dynamics of complex contagions over multiplex networks and their monoplex projections, we demonstrate that ignoring link types and aggregating network layers may lead to inaccurate conclusions about contagion dynamics, particularly when the correlation of degrees between layers is high.

description: Many researchers and research institutions wish to quantify the impact their research output has achieved - whether societal or scientific - and incorporate this information into research profile systems. The available data sources usually range from classical citation databases to various providers of so-called alternative metrics (Altmetrics). In the ROSI project we have developed a prototype that collects scientometric data from open data sources such as Paperbuzz and CrossRef Event Data API. In this presentation, we will first explain the iterative development process in which researchers from the humanities, social sciences, engineering and science were asked about their preferences and requirements. This resulted in a prototype that was subjected to a further round of criticism from the disciplines mentioned above, including focus group workshops. The prototype is capable of feeding different types of impact with indicators from different data sources. We will explain the technical setup of the open source application (JavaScript, open APIs, JSON) and demonstrate its features like configuration, customisation and visualization. Finally, we will explain the most important design decisions and show how the ROSI prototype can be used within VIVO.

description: We examine the ground-state phase diagram and thermal phase transitions in a plaquettized fully frustrated bilayer spin-1/2 Heisenberg model. Based on a combined analysis from sign-problem free quantum Monte Carlo simulations, perturbation theory and free-energy arguments, we identify a first-order quantum phase transition line that separates two competing quantum-disordered ground states with dominant singlet formations on inter-layer dimers and plaquettes, respectively. At finite temperatures, this line extends to form a wall of first-order thermal transitions, which terminates in a line of thermal critical points. From a perturbative approach in terms of an effective Ising model description, we identify a quadratic suppression of the critical temperature scale in the strongly plaquettized region. Based on free-energy arguments we furthermore obtain the full phase boundary of the low-temperature dimer-singlet regime, which agrees well with the quantum Monte Carlo data.

description: High levels of deuterium fraction in N$_2$H$^+$ are observed in some pre-stellar cores. Single-zone chemical models find that the timescale required to reach observed values ($D_{\rm frac}^{{\rm N}_2{\rm H}^+} \equiv {\rm N}_2{\rm D}^+/{\rm N}_2{\rm H}^+ \gtrsim 0.1$) is longer than the free-fall time, possibly ten times longer. Here, we explore the deuteration of turbulent, magnetized cores with 3D magnetohydrodynamics simulations. We use an approximate chemical model to follow the growth in abundances of N$_2$H$^+$ and N$_2$D$^+$. We then examine the dynamics of the core using each tracer for comparison to observations. We find that the velocity dispersion of the core as traced by N$_2$D$^+$ appears slightly sub-virial compared to predictions of the Turbulent Core Model of McKee & Tan, except at late times just before the onset of protostar formation. By varying the initial mass surface density, the magnetic energy, the chemical age, and the ortho-to-para ratio of H$_2$, we also determine the physical and temporal properties required for high deuteration. We find that low initial ortho-to-para ratios ($\lesssim 0.01$) and/or multiple free-fall times ($\gtrsim 3$) of prior chemical evolution are necessary to reach the observed values of deuterium fraction in pre-stellar cores.

description: Soft X-rays (90-173 eV) from the 3rd generation Canadian Light Source have been used in conjunction with a multi coincidence time and position sensitive detection apparatus to observe the dissociative ionization of OCS. By varying the X-ray energy we can compare dynamics from direct and Auger ionization processes, and access ionization channels which result in two or three body breakup, from 2+ to 4+ ionization states. We make several new observations for the 3+ state such as kinetic energy release limited by photon energy, and using Dalitz plots we can see evidence of timescale effects between the direct and Auger ionization process for the first time. Finally, using Dalitz plots for OCS$^{4+}$ we observe for the first time that breakup involving an O$^{2+}$ ion can only proceed from out of equilibrium nuclear arrangement for S(2p) Auger ionization.

Intention - behavior gap

description: Indiana University-Purdue University Indianapolis (IUPUI)
description: Since the COVID-19 pandemic unexpectedly hit the world, the tourism industry has been impacted in every conceivable area. Environmental issues are recognized and considered essential to solve especially in the tourism industry. It is unavoidable that tourists bring both positive and negative impacts to a destination. Meanwhile, the tourism industry is eager to return to its pre-pandemic tourist numbers and levels of spending that traveler previously engaged in. The young generations, specifically Gen Y and Z, play an important role in the tourism market, and they often embody a mindset that takes into consideration issues of sustainability. However, they are not as active as expected in practicing sustainable travel behaviors. Sustainable tourism development and "green" travel practices are becoming increasingly necessary. The main purpose of this study is to identify the gaps between Gen Y and Z's intentions and their behaviors regarding sustainable travel. This study developed and tested a conceptual framework to understand this dynamic. This study identified two gaps: (a) the behavior-intention gap, which exists between Gen Y & Z's intentions and their behaviors in sustainable travel, and (b) daily life and sustainable travel gap, which is the gap between individuals’ daily sustainable habits and sustainable travel behaviors. The results of quantitative study indicated the factors contributed to the gaps included: (1) individuals who have bachelor’s degrees are more likely to conduct sustainable travel behaviors; (2) individuals who have daily sustainable habits; (3) individuals who have higher perceived consumer effectiveness. The implications of the study provide suggestions for destinations to promote sustainable travel and ways to encourage more sustainable traveling choices by travelers.

description: We present a search for transient and highly variable sources at low radio frequencies (150-200 MHz) that explores long timescales of 1-3 years. We conducted this search by comparing the TIFR GMRT Sky Survey Alternative Data Release 1 (TGSS ADR1) and the GaLactic and Extragalactic All-sky Murchison Widefield Array (GLEAM) survey catalogues. To account for the different completeness thresholds in the individual surveys, we searched for compact GLEAM sources above a flux density limit of 100 mJy that were not present in the TGSS ADR1; and also for compact TGSS ADR1 sources above a flux density limit of 200 mJy that had no counterpart in GLEAM. From a total sample of 234 333 GLEAM sources and 275 612 TGSS ADR1 sources in the overlap region between the two surveys, there were 99658 GLEAM sources and 38 978 TGSS ADR sources that passed our flux density cutoff and compactness criteria. Analysis of these sources resulted in three candidate transient sources. Further analysis ruled out two candidates as imaging artefacts. We analyse the third candidate and show it is likely to be real, with a flux density of 182 +/- 26 mJy at 147.5 MHz. This gives a transient surface density of rho = (6.2 +/- 6) x 10-5 deg-2 . We present initial follow-up observations and discuss possible causes for this candidate. The small number of spurious sources from this search demonstrates the high reliability of these two new low-frequency radio catalogues.

description: Solar Ring (SOR) is a proposed space science mission to monitor and study the Sun and inner heliosphere from a full 360° perspective in the ecliptic plane. It will deploy three 120°-separated spacecraft on the 1-AU orbit. The first spacecraft, S1, locates 30° upstream of the Earth, the second, S2, 90° downstream, and the third, S3, completes the configuration. This design with necessary science instruments, e.g., the Doppler-velocity and vector magnetic field imager, wide-angle coronagraph, and in-situ instruments, will allow us to establish many unprecedented capabilities: (1) provide simultaneous Doppler-velocity observations of the whole solar surface to understand the deep interior, (2) provide vector magnetograms of the whole photosphere - the inner boundary of the solar atmosphere and heliosphere, (3) provide the information of the whole lifetime evolution of solar featured structures, and (4) provide the whole view of solar transients and space weather in the inner heliosphere. With these capabilities, Solar Ring mission aims to address outstanding questions about the origin of solar cycle, the origin of solar eruptions and the origin of extreme space weather events. The successful accomplishment of the mission will construct a panorama of the Sun and inner-heliosphere, and therefore advance our understanding of the star and the space environment that holds our life.

description: Sharp structures in magnetic field-dependent spin Seebeck effect (SSE) voltages of Pt/Y$_{3}$Fe$_{5}$O$_{12}$ (YIG) at low temperatures are attributed to the magnon-phonon interaction. Experimental results are well reproduced by a Boltzmann theory that includes the magnetoelastic coupling (MEC). The SSE anomalies coincide with magnetic fields tuned to the threshold of magnon-polaron formation. The effect gives insight into the relative quality of the lattice and magnetization dynamics.

description: We investigate the structure of a particular class of massive vacuum Feynman integrals at two loops. This class enjoys the linear relation $m_1+m_2=m_3$ between its three propagator masses, corresponding to zeros of the associated Källén function. Apart from having applications in thermal field theory, the integrals can be mapped onto one-loop three-point functions with collinear external momenta, suggesting the term "collinear" masses. We present a closed-form solution for these integrals, proving that they can always be factorized into products of one-loop cases, for all integer-valued propagator powers.

description: Predicting popularity, or the total volume of information outbreaks, is an important subproblem for understanding collective behavior in networks. Each of the two main types of recent approaches to the problem, feature-driven and generative models, have desired qualities and clear limitations. This paper bridges the gap between these solutions with a new hybrid approach and a new performance benchmark. We model each social cascade with a marked Hawkes self-exciting point process, and estimate the content virality, memory decay, and user influence. We then learn a predictive layer for popularity prediction using a collection of cascade history. To our surprise, Hawkes process with a predictive overlay outperform recent feature-driven and generative approaches on existing tweet data [43] and a new public benchmark on news tweets. We also found that a basic set of user features and event time summary statistics performs competitively in both classification and regression tasks, and that adding point process information to the feature set further improves predictions. From these observations, we argue that future work on popularity prediction should compare across feature-driven and generative modeling approaches in both classification and regression tasks.
Gender Based Violence and Risk of HIV Infection among Women Attending VCT Services in Addis Ababa City

description: Background: HIV/AIDS and violence are among the major health problems affecting the lives of millions of women, worldwide. As women get increasingly infected by HIV/AIDS, violence and fear of violence are emerging as important risk factors contributing to their vulnerability to HIV infection, directly through forced sex and indirectly by constraining women's ability to negotiate safe sexual behavior. Few studies linked men's use of violence to their own high risk sexual behavior, hence, their own as well as their partner's risk of HIV infection. Despite the recognition of both problems of violence and HIV in Ethiopia, no study yet assessed gender based violence as a risk factor for women's HIV infection. Objectives: This study was conducted: to measure the prevalence of various forms of gender based violence, including intimate partner physical and sexual violence and to assess associations between gender-based violence, HIV risk behaviors and HIV infection among women attending voluntary counseling and testing service in Addis Ababa City. Methods: We did a cross sectional study among 743 women attending VCT service at six health institutions in Addis Ababa City. Women who ever engaged in steady heterosexual relationship interviewed and socio-demographic characteristics, risk behavior including multiple male partners, casual partners, transactional sex, condom use and alcohol/Khat use and experience of psychological, physical and sexual violence from intimate partner, childhood sexual assault, forced first intercourse and sexual assault by non partners were assessed using structured questionnaire and linked with women serostatus data. ix RESULT: The prevalence of lifetime intimate partner physical and sexual violence was 54.6% and 41% respectively and 21.8% of women reported experiencing forced sex or rape at their first sex. At the date of interview 35.4% of women tested HIV positive. After adjustment for socio-demographic characteristics and women risk behavior, intimate partner violence was associated with HIV seropositivity. Childhood sexual assault, forced first intercourse and adult sexual assault by non partner were not associated with HIV serostatus. In our study participants, condom use, refusal of sex and demand for monogamous relationship was affected by intimate partner violence. CONCLUSION: in our study participants, women partnered with violent men are at increased risk of HIV infection. Our data support the hypotheses that abusive partners are more likely to have HIV and place their female partners at high risk of HIV. HIV/AIDS intervention need to target male sexual risk taking and need to work at broader and societal level to challenge cultures of violence and male dominant norms of power relations.
