description: We study the fluctuations of time-additive random observables in the stochastic dynamics of a system of $N$ non-interacting Ising spins. We mainly consider the case of all-to-all dynamics where transitions are possible between any two spin configurations with uniform rates. We show that the cumulant generating function of the time-integral of a normally distributed quenched random function of configurations, i.e., the energy function of the random energy model (REM), has a phase transition in the large $N$ limit for trajectories of any time extent. We prove this by determining the exact limit of the scaled cumulant generating function. This is accomplished by connecting the dynamical problem to a spectral analysis of the all-to-all quantum REM. We also discuss finite $N$ corrections as observed in numerical simulations.

description: We present new molecular gas maps of NGC5195 (alternatively known as M51b) from the Combined Array for Research in Millimeter Astronomy (CARMA), including 12CO(1-0), 13CO(1-0), CN(1-0), and CS(2-1). NGC5195 has also been detected in 3mm continuum. NGC5195 has a 12CO/13CO ratio consistent with normal star-forming galaxies. The CN(1-0) intensity is higher than is seen in an average star-forming galaxy, possibly enhanced in the diffuse photo-dissociation regions. Stellar template fitting of the nuclear spectrum of NGC5195 shows two stellar populations: an 80% mass fraction of old (>10Gyr) and a 20% mass fraction of intermediate-aged (~1Gyr) stellar populations, providing a constraint on the timescale over which NGC5195 experienced enhanced star formation during its interaction with M51a. The average molecular gas depletion timescale in NGC5195 is: tdep=3.08Gyr, a factor of ~2 larger than the depletion timescales in nearby star-forming galaxies, but consistent with the depletion seen in CO-detected early-type galaxies. While the radio continuum emission at centimeter and millimeter wavelengths is present in the vicinity of the nucleus of NGC5195, we find it is most likely associated with nuclear star formation rather than a radio-loud AGN. Thus, despite having a substantial interaction with M51a ~1/2Gyr ago, the molecular gas in NGC5195 has resettled and is forming stars at an efficiency consistent with settled early-type galaxies at the present time.

description: In this paper we study the problem of exact recovery of the pure-strategy Nash equilibria (PSNE) set of a graphical game from noisy observations of joint actions of the players alone. We consider sparse linear influence games --- a parametric class of graphical games with linear payoffs, and represented by directed graphs of n nodes (players) and in-degree of at most k. We present an $\ell_1$-regularized logistic regression based algorithm for recovering the PSNE set exactly, that is both computationally efficient --- i.e. runs in polynomial time --- and statistically efficient --- i.e. has logarithmic sample complexity. Specifically, we show that the sufficient number of samples required for exact PSNE recovery scales as $\mathcal{O}(\mathrm{poly}(k) \log n)$. We also validate our theoretical results using synthetic experiments.

description: Over the last few decades several types of Terahertz (THz) detectors have been developed to maturity, paving the way for various potential applications such as diagnostics of THz generation at particle accelerators. An important class are zero-biased Schottky diode THz detectors that are frequently applied at accelerator facilities for operation at room temperature. Zero-biased Schottky diode THz detectors are having lower noise compared to biased ones due to the absence of shot noise. Here we demonstrate the sensitivity of Schottky detectors using a commercial continuous wave photomixing THz system as source. Both, a commercially available as well as a research-grade compact quasi-optical detector with improved video bandwidth are compared from 0.05 to 1.2 THz in terms of sensitivity. At 1 THz, the research grade quasi optical detector shows 7 dB higher dynamic range than the commercial one.

description: Machine learning is emerging as a technology that can enhance physics experiment execution and data analysis. Here, we apply machine learning to accelerate the production of a Bose-Einstein condensate (BEC) of $^{87}\mathrm{Rb}$ atoms by Bayesian optimization of up to 55 control parameters. This approach enables us to prepare BECs of $2.8 \times 10^3$ optically trapped $^{87}\mathrm{Rb}$ atoms from a room-temperature gas in 575 ms. The algorithm achieves the fast BEC preparation by applying highly efficient Raman cooling to near quantum degeneracy, followed by a brief final evaporation. We anticipate that many other physics experiments with complex nonlinear system dynamics can be significantly enhanced by a similar machine-learning approach.

description: We investigate the consequences of fairly normal Type Ia supernovae being embedded in compact and dense envelopes of carbon and oxygen rich circumstellar material by means of detailed radiation hydrodynamic simulations. Our main focus rests on exploring the effects of the interaction between ejecta and circumstellar material on the ejecta evolution and the broad-band light curve. In our calculations, we find that a strong reverse shock efficiently decelerates and compresses the ejecta material. This leads to a significant broadening of the optical light curve, a longer rise to maximum and a slower decline in the tail phase. During the interaction, substantial radiative energy is generated, which mostly emerges in the extreme ultraviolet and X-ray regime. Only if reprocessing due to radiation-matter interactions is very efficient, a significant boost in the optical light curve is observed. We discuss these findings in particular in the context of the super-luminous event SN 2009dc. As our calculations are able to reproduce a number of its peculiar properties, we conclude that the flavour of the interaction scenario investigated in this work constitutes a promising candidate to explain such 'Super-Chandrasekhar' supernovae.

Assessment of the operational capacity of health center governing body Sokoru Woreda, Jimma Zone, Oromia, Ethiopia
Creators: name: Shifa, Kemeredin
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Background Governing body is responsible to provide strategic leadership at facility level. The facility governing body is committed to create and maintaining a strong bond between the health center and the community it serves. This governing body has the primary authority and responsibility for patient care, overall quality of service and on-going capability of the health center. To realize this, the introduction of health care financing has been introduced in Ethiopia since 1998 nationally. Good health facility governance is characterized by responsiveness and accountability; an open and transparent policy process; participatory engagement of citizens; and operational capacity of government to plan, manage, and regulate policy and service delivery. Nevertheless the performance of this governing body is not well documented in Ethiopia Objective: the aim of this study was to assess the operational capacity of health center governing body and management teams, Methodology: Descriptive qualitative method was employed. Semi Structured questionnaire was used to interview management and governing body members of six health centers selected from sokoru woreda. In-depth interviews and focus group discussions were conducted with purposively selected health extension workers, health center staffs, community leaders and health managers from Woreda and Zonal Health office. Results: - More than 15 (62.5%) of respondents indicated that they were concerned about the unclear authority of the health center governing body. Some expressed boundary problems with the health center management and other respondents emphasized the boundary problems with the woreda health office. The ambiguity in authority was apparent in statements about decisions concerning financial incentives for the staff, handling ethical issues, drug procurement, corrective action for employees, these result was supported by study conducted in Ethiopian hospitals. Conclusion and Recommendation: These qualitative results were suggested that strengthening governing body to perform essential responsibilities may result in improved health center performance. Recommendation: The performance of the governing body would be enhanced by ensuring proper selection, constitution, capacitation, integration and interaction with other institutions must be conducted.

description: The Borel map takes a smooth function to its infinite jet of derivatives (at zero). We study the restriction of this map to ultradifferentiable classes of Beurling type in a very general setting which encompasses the classical Denjoy-Carleman and Braun-Meise-Taylor classes. More precisely, we characterize when the Borel image of one class covers the sequence space of another class in terms of the two weights that define the classes. We present two independent solutions to this problem, one by reduction to the Roumieu case and the other by dualization of the involved Fréchet spaces, a Phragmén-Lindelöf theorem, and Hörmander's solution of the $\bar{\partial}$-problem.

description: We present multiple-epoch measurements of the size and surface brightness of the light echoes from supernova (SN) 2014J in the nearby starburst galaxy M82. Hubble Space Telescope (HST) ACS/WFC images were taken ~277 and ~416 days after B-band maximum in the filters F475W, F606W, and F775W. Observations with HST WFC3/UVIS images at epochs ~216 and ~365 days (Crotts 2015) are included for a more complete analysis. The images reveal the temporal evolution of at least two major light-echo components. The first one exhibits a filled ring structure with position-angle-dependent intensity. This radially extended, diffuse echo indicates the presence of an inhomogeneous interstellar dust cloud ranging from ~100 pc to ~500 pc in the foreground of the SN. The second echo component appears as an unresolved luminous quarter-circle arc centered on the SN. The wavelength dependence of scattering measured in different dust components suggests that the dust producing the luminous arc favors smaller grain sizes, while that causing the diffuse light echo may have sizes similar to those of the Milky Way dust. Smaller grains can produce an optical depth consistent with that along the supernova-Earth line of sight measured by previous studies around maximum light. Therefore, it is possible that the dust slab, from which the luminous arc arises, is also responsible for most of the extinction towards SN 2014J. The optical depths determined from the Milky Way-like dust in the scattering matters are lower than that produced by the dust slab.

description: Multiple exciton generation is a process in which more than one electron hole pair is generated per absorbed photon. It allows us to increase the efficiency of solar energy harvesting. Experimental studies have shown the multiple exciton generation yield of 1.2 in isolated colloidal quantum dots. However real photoelectric devices require the extraction of electron hole pairs to electric contacts. We provide a systematic study of the corresponding quantum coherent processes including extraction and injection and show that a proper design of extraction and injection rates enhances the yield significantly up to values around 1.6.

The importance of temperature dependent energy gap in the understanding of high temperature thermoelectric properties

description: In the present work, we show the importance of temperature dependent energy band gap, E$_{g}$(T), in understanding the high temperature thermoelectric (TE) properties of material by considering LaCoO$_{3}$ (LCO) and ZnV$_{2}$O$_{4}$ (ZVO) compounds as a case study. For the fix value of band gap, E$_{g}$, deviation in the values of $α$ has been observed above 360 K and 400 K for LCO and ZVO compounds, respectively. These deviation can be overcomed by consideration of temperature dependent band gap. The change in used value of E$_{g}$ with respect to temperature is $\sim$4 times larger than that of InAs. This large temperature dependence variation in E$_{g}$ can be attributed to decrement in the effective on-site Coulomb interaction due to lattice expansion. At 600 K, the value of \textit{ZT} for \textit{n} and \textit{p-doped}, LCO is $\sim$0.35 which suggest that it can be a used as a potential material for TE device. This work clearly suggest that one should consider the temperature dependent band gap in predicting the high temperature TE properties of insulating materials.

description: A non-orthogonal multiple access (NOMA)-aided joint communication, sensing, and multi-tier computing (JCSMC) framework is proposed. In this framework, a multi-functional base station (BS) carries out target sensing, while providing edge computing services to the nearby users. To enhance the computation efficiency, the multi-tier computing structure is exploited, where the BS can further offload the computation tasks to a powerful Cloud server (CS). The potential benefits of employing NOMA in the proposed JCSMC framework are investigated, which can maximize the computation offloading capacity and suppress the inter-function interference. Based on the proposed framework, the transmit beamformer of the BS and computation resource allocation at the BS and the CS are jointly optimized to maximize the computation rate subject to the communication-computation causality and the sensing quality constraints. Both partial and binary computation offloading modes are considered: 1) For the partial offloading mode, a weighted minimum mean square error based alternating optimization algorithm is proposed to solve the corresponding non-convex optimization problem. It is proved that a KKT optimal solution can be obtained; 2) For the binary offloading mode, the resultant highly-coupled mixed-integer optimization problem is first transformed to an equivalent but more tractable form. Then, the reformulated problem is solved by utilizing the alternating direction method of multipliers approach to obtain a nearly optimal solution. Finally, numerical results verify the effectiveness of the proposed algorithms and the proposed NOMA-aided JCSMC framework

description: We have developed Norland Optical Adhesive (NOA) flow focusing devices, making use of the excellent solvent compatibility and surface properties of NOA to generate micron scale oil-in-water emulsions with polydispersities as low as 5%. While current work on microfluidic oil-in-water emulsification largely concerns the production of droplets with sizes on the order of 10s of micrometres, large enough that Brownian motion is negligible, our NOA devices can produce droplets with radii ranging from 2 μm to 12 μm. To demonstrate the utility of these emulsions as colloidal model systems we produce fluorescently labelled polydimethylsiloxane droplets suitable for particle resolved studies with confocal microscopy. We analyse the structure of the resulting emulsion in 3D using coordinate tracking and the topological cluster classification and reveal a new mono-disperse thermal system.

description: Boson Sampling represents a promising approach to obtain an evidence of the supremacy of quantum systems as a resource for the solution of computational problems. The classical hardness of Boson Sampling has been related to the so called Permanent-of-Gaussians Conjecture and has been extended to some generalizations such as Scattershot Boson Sampling, approximate and lossy sampling under some reasonable constraints. However, it is still unclear how demanding these techniques are for a quantum experimental sampler. Starting from a state of the art analysis and taking account of the foreseeable practical limitations, we evaluate and discuss the bound for quantum supremacy for different recently proposed approaches, accordingly to today's best known classical simulators.

description: Quantum materials with a large charge current-induced spin polarization are promising for next-generation all-electrical spintronic science and technology. Van der Waals metals with high spin-orbit coupling and novel spin textures have attracted significant attention for an efficient charge to spin conversion process. Here, we demonstrate the electrical generation of spin polarization in NbSe2 up to room temperature. To probe the current-induced spin polarization in NbSe2, we used a graphene-based non-local spin-valve device, where the spin-polarization in NbSe2 is efficiently injected and detected using non-local spin-switch and Hanle spin precession measurements. A significantly higher charge-spin conversion in NbSe2 is observed at a lower temperature, below the superconducting transition temperature Tc ~ 7 K of NbSe2. However, the charge-spin conversion signal could only be observed with a higher bias current above the superconducting critical current, limiting the observation of the signal only to the non-superconducting state of NbSe2. Systematic measurements provide the possible origins of the spin polarization to be predominantly due to the spin Hall effect or Rashba-Edelstein effect in NbSe2, considering different symmetry allowed charge-spin conversion processes.

description: Background: Measles is the leading causes of death among young children. Though a safe and cost-effective vaccine is available measles occur as outbreak. In 2013, there were 145,700 measles deaths globally. In Africa, about 13 million cases and 650,000 deaths occur annually, with sub-Saharan Africa having the highest morbidity and mortality. Due to an increase in vaccination coverage in developing countries there has been a significant change in the epidemiology of measles such as higher incidence in older children and young adults. The aim of investigation was to assess risk factors and institute doable intervention measures. Methods: We applied the case definition, a maculopapular rash and fever with coryza, conjunctivitis or cough, to select cases of measles. We conducted 1:2 unmatched case-control study from May 2-10 /2015. Data was collected using structured questionnaire. Analysis was done using Epi Info 7 and SPSS software. Then, Odds Ratio with 95% CI and P-value were used to measure the significance of association in bivariate and multivariate analysis. Results: Of 143 reported cases, half of them were females. The median age of cases was10 (Q1=4, Q3=19) years while that of controls was 9 (Q1=5, Q3=15) years. The overall attack rate (AR) was 218/100,000. It was higher among 15-44 years (471/100,000). No death reported throughout the outbreak. Being vaccinated against measles was 85% less likely contracting measles [AOR: 0.15, (95% CI: 0.06, 0.38, P< 0.0001)], contact history with cases [AOR: 7.1, (95% CI: 2.4, 12.6, P < 0.0001)]. Conclusion: Adults and children greater 15 years old were more affected. Absence of vaccination and contact with cases were found to be risk factors. We searched cases house to house and provided case management to stop the epidemic. Strengthening the routine surveillance activity and EPI program were recommended to the district health office.

description: Field effect transistor (FET) based terahertz rectifiers are promising candidates for sensitive, room-temperature operated high speed (THz) detectors, e.g. in communication, medical, biochemical, security, quality control applications, or beam diagnostic applications at particle accelerators. This paper investigates the equivalent circuit in the intermediate frequency band from 0.1 to 65 GHz with S-parameter measurements in order to enable implementation with high speed post detection electronics. Preliminary results are obtained by de-embedding On-Wafer measurements and compared with theoretical expectations from hall measurements and a simplified equivalent circuit. The knowledge of the channel behavior and impedance is mandatory for impedance matching to IF circuitry in advanced detector designs.

description: The scintillation mechanism in NaI:Tl crystals produces different pulse shapes that are dependent on the incoming particle type. The time distribution of scintillation light from nuclear recoil events decays faster than for electron recoil events and this difference can be categorised using various Pulse Shape Discrimination (PSD) techniques. In this study, we measured nuclear and electron recoils in a NaI:Tl crystal, with electron equivalent energies between 2 and 40 keV. We report on a new PSD approach, based on an event-type likelihood; this outperforms the charge-weighted mean-time, which is the conventional metric for PSD in NaI:Tl. Furthermore, we show that a linear combination of the two methods improves the discrimination power at these energies.

description: Background: - Fatalities from hypertension in East Africa are increasing even though it decreased in western industrial regions. Older age, female, illiterate, smoking, physical inactivity and high waist circumferences are major risk factors for the development of hypertension. The prevalence of Hypertension among federal ministry civil servants in Addis Ababa was found to be high; which is an indication for institution based hypertension-screening programs. This study aimed to collect and organize the data about prevalence and associated factors of hypertension. Objective: - To assess the prevalence and major associated factors of hypertension among Outpatient attendants at Health Centers in Akaki Kality Sub-City. Methodology: - Cross-sectional study was conducted on 401 outpatient attendants whose age were greater or equal to 18 years from the four Government Health Centers in Akaki Kality sub-city. Systematic random Sampling was used to select study subjects from each Health Center. The data were collected by face-to-face interview. A structured pre tested questionnaire was used for data collection. The questionnaire was adopted from WHO STEPWISE survey and included additional information. In addition, blood pressure was measured using manual sphygmomanometer and stethoscope, Weight by adult weight scale, Height by tape meter and BMI was calculated. Results: - The overall prevalence of hypertension was found to be 14% (95% CI: 13.653-14.347); of which 30 (53.57%) were males (P- value > 0.05). Based on this data, alcohol drinkers were 11.844 times more likely to be hypertensive compared to non-alcohol drinkers (AOR= 11.844, 95% CI: 3.596-39.014). Cigarette smokers were 16.511 times more likely to be hypertensive compared to non-cigarette smokers (AOR= 16.511, 95% CI: 4.775-57.084). Khat chewers were 6.964 times more likely to be hypertensive compared to non-chat chewers (AOR= 6.964, 95% CI: 1.773-26.889). BMI (AOR=1.320, 95% CI: 1.149-1.516) and age (AOR=1.040, 95% CI: 1.004-1.077) were also significantly associated with hypertension. Conclusion: - The prevalence of hypertension is 14% among OPD attendants in Akaki Kality health centres. Alcohol drinking, cigarette smoking, Khat chewing, BMI ≥ 25 kg/m2 and Age ≥ 44 years old are major determinants identified by this study.

description: Stimulated emission tomography is a powerful and successful technique to both improve the resolution and experimentally simplify the task of determining the modal properties of biphotons. In the present manuscript we provide a theoretical description of SET valid for any quadratic coupling regime between a non-linear medium and pump fields generating photons by pairs. We use our results to obtain not only information about the associated modal function modulus but also its phase, for any mode, and we discuss the specific case of time-frequency variables as well as the quantities and limitations involved in the measurement resolution.

Solution of the classical Yang--Baxter equation with an exotic symmetry, and integrability of a multi-species boson tunneling model

description: Solutions of the classical Yang-Baxter equation provide a systematic method to construct integrable quantum systems in an algebraic manner. A Lie algebra can be associated with any solution of the classical Yang--Baxter equation, from which commuting transfer matrices may be constructed. This procedure is reviewed, specifically for solutions without skew-symmetry. A particular solution with an exotic symmetry is identified, which is not obtained as a limiting expansion of the usual Yang--Baxter equation. This solution facilitates the construction of commuting transfer matrices which will be used to establish the integrability of a multi-species boson tunneling model. The model generalises the well-known two-site Bose-Hubbard model, to which it reduces in the one-species limit. Due to the lack of an apparent reference state, application of the algebraic Bethe Ansatz to solve the model is prohibitive. Instead, the Bethe Ansatz solution is obtained by the use of operator identities and tensor product decompositions.

description: This research probes probable role of elemene injection on pancreatic cancer employing network pharmacology and experimental validation.GEO database were used to acquire genes which is differentially expressed between pancreatic cancer tissue with normal tissue. The vigorous energetic ingredients were identified consequent a reading search and the object genes of were obtained from BATMAN-TCM. Subsequently, a Venn diagram was constructed to visualize the common genes. Screening for survival-related genes was performed using the GEPIA database. Moreover, docking and co-immunoprecipitation studies were performed to verify the suggested contact between the elemene components and target genes. In vitro experiments using pancreatic cell lines, including Panc02, Mia PaCa-2, and Capan-1 and in vivo experiments using Panc02-injected C57BL/6 mice were conducted for further validation.Twenty-seven target genes that potentially mediate elemene’s effect on pancreatic cancer were obtained. The experiments verified that elemene injection suppresses pancreatic cancer cell expansion, blocks cells in S phase, and causes apoptosis by upregulating EPHX2 and downregulating EFNA5 in vitro and in vivo.The mechanism may be related to induced EPHX2 overexpression and EFNA5 hypoexpression. Both EPHX2 and EFNA5 are new targets for pancreatic cancer treatment that require further investigation.

description: Given an arbitrary connected $G$, the $n$-polygon graph $τ_n(G)$ is obtained by adding a path with length $n$ $(n\geq 2)$ to each edge of graph $G$, and the iterated $n$-polygon graphs $τ_n^g(G)$ ($g\geq 0$), is obtained from the iteration $τ_n^g(G)=τ_n(τ_n^{g-1}(G))$, with initial condition $τ_n^0(G)=G$. In this paper, a method for calculating the eigenvalues of normalized Laplacian matrix for graph $τ_n(G)$ is presented if the eigenvalues of normalized Laplacian matrix for graph $G$ is given firstly. Then, the normalized Laplacian spectrums for the graph $τ_n(G)$ and the graphs $τ_n^g(G)$ ($g\geq 0$) can also be derived. Finally, as applications, we calculate the multiplicative degree-Kirchhoff index, Kemeny's constant and the number of spanning trees for the graph $τ_n(G)$ and the graphs $τ_n^g(G)$ by exploring their connections with the normalized Laplacian spectrum, exact results for these quantities are obtained.

description: Motivated by recent proposals of possible wormhole existence in galactic halos, we analyse the cosmological evolution of wormhole solutions in modified $f(R)$ gravity. We construct a dynamical wormhole that asymptotically approaches FLRW universe, with supporting material going to the perfect isotropic fluid described by the equation of state for radiation and matter dominated universe respectively. Our analysis is based on an approximation of a small wormhole - a wormhole that can be treated as matched with the FLRW metric at some radial coordinate much smaller than the Hubble radius, so that cosmological boundary conditions are satisfied. With a special interest in viable wormhole solutions, we refer to the results of reconstruction procedure and use $f(R)$ functions which lead to the experimentally confirmed $Λ$CDM expansion history of the Universe. Solutions we find imply no need for exotic matter near the throat of considered wormholes, while in the limit of $f(R)=R$ this need is always present during radiation and matter dominated epoch.

description: Introduction: Male partner involvement in antenatal voluntary HIV counseling and testing (VCT) has been shown to increase uptake of interventions to reduce the risk of HIV transmission in resource-limited settings. We aimed to identify methods for increasing male involvement in antenatal VCT and determine male correlates of accepting couple counseling and how to improve these 4% of partner HIV testing. Methodology: We invited women presenting to Korem health center in antenatal clinic to return with their male partners for individual or couples VCT. Male attitudes towards VCT and correlates of accompanying female partners to antenatal clinic and receiving couple counseling were determined. Results: Of a total 225 ANC client the response rate was 95% (214), 87% (n=96), and 85% (n=191) the respondent rate were married, Tigray and orthodox followers respectively. The majority (58%) aged 19-44 years old. From the total 214 ANC clients, 145(67.8%) ANC clients brought their male partner, of which140 (96.6%) were tested as couple while the rest 5 declined to test. Sixty nine (32.2%) of the 214 ANC clients did not want to bring their male partner when invitation letter was sent. HIV prevalence among the tested couples in this study was 3.5%. Conclusions: Formulated invitation card, increasing awareness of male partner for HIV counseling and testing, and offering men at antenatal clinic with options for couple and individual counseling could increase partner HIV testing and counseling in ANC significantly, from 4% to 65.4%, at Korem health center. It was found to be an important opportunity and acceptable strategy for increasing male involvement in PMTCT and promoting male HIV testing with low cost and feasible intervention. All health center management team and board members should be committed to pursue this strategy in order to sustain it as a system. The use of weekends, in addition to the weekdays, could make the service more accessible for large proportion of "busy" clients. Future studies could benefit from such designs
