description: We use numerical relativity simulations to describe the spacetime evolution during nonlinear structure formation in $Λ$CDM cosmology. Fully nonlinear initial conditions are set at an initial redshift $z\approx 300$, based directly on the gauge invariant comoving curvature perturbation $\mathcal{R}_c$ commonly used to model early-universe fluctuations. Assigning a simple 3-D sinusoidal structure to $\mathcal{R}_c$, we then have a lattice of quasi-spherical over-densities representing idealised dark matter halos connected through filaments and surrounded by voids. This structure is implemented in the synchronous-comoving gauge, using a pressureless perfect fluid (dust) description of CDM, and then it is fully evolved with the Einstein Toolkit code. With this, we look into whether the Top-Hat spherical and homogeneous collapse model provides a good description of the collapse of over-densities. We find that the Top-Hat is an excellent approximation for the evolution of peaks, where we observe that the shear is negligible and collapse takes place when the linear density contrast reaches the predicted critical value $δ^{(1)}_C =1.69$. Additionally, we characterise the outward expansion of the turn-around boundary and show how it depends on the initial distribution of matter, finding that it is faster in denser directions, incorporating more and more matter in the infalling region. Using the EBWeyl code [1] we look at the distribution of the electric and magnetic parts of the Weyl tensor, finding that they are stronger along and around the filaments, respectively. We introduce a method to dynamically classify different regions in Petrov types. With this, we find that the spacetime is of Petrov type I everywhere, as expected, but we can identify the leading order type, finding a transition between different types as non-linearity grows, with production of gravitational waves.

description: The EU-funded project CIRCULAR FoodPack comprises different loops, demonstrating the circular use of plastic packaging material. One of those loops aims for the circularity of PE-based mono-material food-grade packaging items, running two cycles of packaging production, sorting, and recycling.

Films marked with tracers and subsequently sorted tracer-based in a sorting line, have been washed, de-inked and were processed to regranulates for use by a convertor. This process included additional drying, densification and extrusion to regranulates, consecutively. During extrusion, 5wt% anti-oxidant stabilizer was added, as is common for poly-ethylene. The resulting granulates were of good quality and suitable for film blowing into 25 m film at the downstream convertor. This deliverable contains the characterisation of this recyclate and the produced film.

Points of attention are material losses for each step of the process (also preceding this work) and deposition of colourant on the equipment, which must be further investigated.

description: Motivated by recent experiments, we present here a systematic ab-initio study of the length dependence of the thermal conductance of single-molecule junctions. We make use of a combination of density functional theory with non-equilibrium Green's function techniques to investigate the length dependence of the phonon transport in single alkane chains, contacted with gold electrodes via both thiol and amine anchoring groups. Additionally, we study the effect of the substitution of the hydrogen atoms in the alkane chains by heavier fluorine atoms to form polytetrafluoroethylenes. Our results demonstrate that (i) the room-temperature thermal conductance is fairly length-independent for chains with more than 5 methylene units and (ii) the efficiency of the thermal transport is strongly influenced by the strength of the phononic metal-molecule coupling. Our study sheds new light onto the phonon transport in molecular junctions, and it provides clear guidelines for the design of molecular junctions for thermal management.

description: Background: public health officer is a field of study in Ethiopia for non physicians' clinicians. This was started in 1954 EC in Gonder college of Public Health to meet the health needs of rural communities. Objective- To explore the perceptions of public health officers on whether the curriculum prepares them for clinical practice in the real environment. Methodology-A qualitative research design will be used to explore health officers perceptions of whether the curriculum prepares them for clinical practice. Data collection will done using semistructured interview guide with open ended questions. The questions will be developed using personal experience and key informants. The source population for this study will be a graduated public health officers who will be interviewed until saturation of data is reached. Data analysis was begun with translation from Amharic to English during the transcription process. A thematic analysis approach was used. Result- the result of the study has revealed that some major curriculum related gap which contributes for perceived knowledge gap of public health officers. The main gap are disproportional time allocation for very crucial courses of basic sciences and clinical. The curriculum lack strict monitoring system of its implementation. Conclusion- Based on the result of this study some strength and weakness of the curriculum are identified. Some of the strength is mentioned are strong course content of both clinical and public courses. The main weakness in the curriculum is some of the courses are not proportionally allocated with adequate time and course contents like that of basic science and clinical courses.

description: We use the large spectroscopic dataset of the MOSFIRE Deep Evolution Field (MOSDEF) survey to investigate some of the key factors responsible for the elevated ionization parameters (U) inferred for high-redshift galaxies, focusing in particular on the role of star-formation-rate surface density (Sigma_SFR). Using a sample of 317 galaxies with spectroscopic redshifts z~1.9-3.7, we construct composite rest-frame optical spectra in bins of Sigma_SFR and infer electron densities, n_e, using the ratio of the [OII] 3727, 3730 doublet. Our analysis suggests a significant (~3 sigma) correlation between n_e and Sigma_SFR. We further find significant correlations between U and Sigma_SFR for composite spectra of a subsample of 113 galaxies, and for a smaller sample of 25 individual galaxies with inferences of U. The increase in n_e -- and possibly also the volume filling factor of dense clumps in HII regions -- with Sigma_SFR appear to be important factors in explaining the relationship between U and Sigma_SFR. Further, the increase in n_e and SFR with redshift at a fixed stellar mass can account for most of the redshift evolution of U. These results suggest that the gas density, which sets n_e and the overall level of star-formation activity, may play a more important role than metallicity evolution in explaining the elevated ionization parameters of high-redshift galaxies.

description: We propose and construct a two-parameter perturbative expansion around a Friedmann-Lemaître-Robertson-Walker geometry that can be used to model high-order gravitational effects in the presence of non-linear structure. This framework reduces to the weak-field and slow-motion post-Newtonian treatment of gravity in the appropriate limits, but also includes the low-amplitude large-scale fluctuations that are important for cosmological modelling. We derive a set of field equations that can be applied to the late Universe, where non-linear structure exists on supercluster scales, and perform a detailed investigation of the associated gauge problem. This allows us to identify a consistent set of perturbed quantities in both the gravitational and matter sectors, and to construct a set of gauge-invariant quantities that correspond to each of them. The field equations, written in terms of these quantities, take on a relatively simple form, and allow the effects of small-scale structure on the large-scale properties of the Universe to be clearly identified. We find that inhomogeneous structures source the global expansion, that there exist new field equations at new orders, and that there is vector gravitational potential that is a hundred times larger than one might naively expect from cosmological perturbation theory. Finally, we expect our formalism to be of use for calculating relativistic effects in upcoming ultra-large-scale surveys, as the form of the gravitational coupling between small and large scales depends on the non-linearity of Einstein's equations, and occurs at what is normally thought of as first order in cosmological perturbations.

description: It has been proposed that the observed diphoton excess at 750 GeV could be explained within the constrained minimal supersymmetric standard model via resonantly produced stop bound states. We reanalyze this scenario critically and extend previous work to include the constraints from the stability of the electroweak vacuum and from the decays of the stoponium into a pair of Higgs bosons. It is shown that the interesting regions of parameter space with a light stop and Higgs of the desired mass are ruled out by these constraints. This conclusion is not affected by the presence of the bound states because the binding energy is usually very small in the regions of parameter space which can explain the Higgs mass. Thus, this also leads to strong constraints on the diphoton production cross section which is in general too small.

description: In this paper we study the asymptotic properties of the adaptive Lasso estimate in high dimensional sparse linear regression models with heteroscedastic errors. It is demonstrated that model selection properties and asymptotic normality of the selected parameters remain valid but with a suboptimal asymptotic variance. A weighted adaptive Lasso estimate is introduced and is investigated. In particular, it is shown that the new estimate performs consistent model selection and that linear combinations of the estimates corresponding to the non-vanishing components are asymptotically normally distributed with a smaller variance than those obtained by the "classical" adaptive Lasso. The results are illustrated in a data example and by means of a small simulation study.

Assessment of magnitude and factors associated with Maternal Near Miss in Public Hospitals of Addis Ababa
Creators: name: Kebede, Feven
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Back ground: Causes of maternal near miss can be classified as direct and indirect causes. The major direct causes of maternal near miss are obstructed or prolonged labor, postpartum hemorrhage, infections, ruptured uterus, severe preeclampsia, eclampsia and unsafe abortion. Among the indirect causes of maternal morbidity and mortality anemia, malaria, hepatitis, tuberculosis and cardiovascular disease account for the highest number of maternal deaths. Objective: To assess magnitude and factors associated with maternal near miss in selected public hospitals of Addis Ababa. Methodology: A retrospective cross-sectional study design was used .A total of 497near miss cases were identified from January 2014 to December 20014 from four selected public hospitals in Addis Ababa. Out of these 321 near miss cases were selected based on proportionally allocated sample size for each hospitals data was collected using data extraction format adopted from WHO. Data was entered into Epi data version 3.1 and transferred to SPSS version 20 and analyzed. To establishes associations between dependent and independent variables and determine possible Association, P values, logistic regression and odds ratio at 95% confidence interval were used, Statistical significance was considered at P-value less than 0.05. RUSELT The reviewed near miss cases were admitted with different diagnosis. The most common types of near-miss events fall under the diagnostic categories of hemorrhage, sevier pre-eclampsia, Eclampsia, ruptured uterus, sepsis and obstructed labor. Heammorrhage was the major 179(55.8%) diagnosis at admission followed by sever preeclampsia 116(36.1%) . The least diagnosis was uterine rupture which accounts for 4 (1.2%). On logistic regression and bivaret multivariate analysis with hemorrhage and SPE; age, parity, gestational age and ANC were significantly associated with OR. Conclusion. There is a high frequency of maternal near miss at the level of these facilities therefore maternal health policy needs to be concerned not only with averting the loss life, but also with preventing maternal near events or factors hemorrhage, hypertension, infection, ruptured uterus at all care levels including primary health care levels and community based level. Recommendation. Therefore maternal health policy needs to be concerned not only with preventing loss of life but also with preventing maternal near miss events like hemorrhage and hypertension disorder and other all health care levels including primary health care by developing management protocols. Key words: Maternal near miss, complication, outcome maternal near miss events.

description: Objective: To investigate the intersection of race and economic context in treatment with hysterectomy among reproductive aged women with noncancerous gynecologic conditions. Data Sources: We combined administrative billing records of inpatient and outpatient hysterectomy procedures (N = 28 301) occurring in North Carolina between 2011 and 2014 with census data to calculate county-level hysterectomy rates. Study Design: Spatial analysis techniques examined the distribution of black and white hysterectomy rates across counties, and county-level black and white rate differences were compared across economic contexts. Data Collection/Extraction: We restricted to those of premenopausal age identifying as non-Hispanic black or white, undergoing hysterectomy for nonemergent causes (N = 28 301 procedures). Principal Findings: County-level hysterectomy rates were spatially patterned (Moran's I, P <.05) and similarly so for black and white women (LISA, P <.005). The black-white difference in hysterectomy rates was the largest in the high economic tier counties (22/10 000 person-years [PY], P <.05) and smallest in the mid and low economic tier counties (11/10 000 PY, P >.05 and 10/10 000 PY, P >.05, respectively). Conclusion: Socioeconomic context is important to understand, particularly for black-white disparities in hysterectomy. Efforts should be made to understand the causes of higher rates of hysterectomy among blacks than whites, especially in counties in the highest economic tier.

description: We present results from a search for solar bosonic dark matter using the annual modulation method with the COSINE-100 experiment. The results were interpreted considering three dark sector bosons models: solar dark photon; DFSZ and KSVZ solar axion; and Kaluza-Klein solar axion. No modulation signal that is compatible with the expected from the models was found from a data-set of 2.82 yr, using 61.3 kg of NaI(Tl) crystals. Therefore, we set a 90$\%$ confidence level upper limits for each of the three models studied. For the solar dark photon model, the most stringent mixing parameter upper limit is $1.61 \times 10^{-14}$ for dark photons with a mass of 215 eV. For the DFSZ and KSVZ solar axion, and the Kaluza-Klein axion models, the upper limits exclude axion-electron couplings, $g_{ae}$, above $1.61 \times 10^{-11}$ for axion mass below 0.2 keV; and axion-photon couplings, $g_{aγγ}$, above $1.83 \times 10^{-11}$ GeV$^{-1}$ for an axion number density of $4.07 \times 10^{13}$ cm$^{-3}$. This is the first experimental search for solar dark photons and DFSZ and KSVZ solar axions using the annual modulation method. The lower background, higher light yield and reduced threshold of NaI(Tl) crystals of the future COSINE-200 experiment are expected to enhance the sensitivity of the analysis shown in this paper. We show the sensitivities for the three models studied, considering the same search method with COSINE-200.

description: Euclid-VIS is the large format visible imager for the ESA Euclid space mission in their Cosmic Vision program, scheduled for launch in 2020. Together with the near infrared imaging within the NISP instrument, it forms the basis of the weak lensing measurements of Euclid. VIS will image in a single r+i+z band from 550-900 nm over a field of view of ~0.5 deg2. By combining 4 exposures with a total of 2260 sec, VIS will reach to deeper than mAB=24.5 (10sigma) for sources with extent ~0.3 arcsec. The image sampling is 0.1 arcsec. VIS will provide deep imaging with a tightly controlled and stable point spread function (PSF) over a wide survey area of 15000 deg2 to measure the cosmic shear from nearly 1.5 billion galaxies to high levels of accuracy, from which the cosmological parameters will be measured. In addition, VIS will also provide a legacy dataset with an unprecedented combination of spatial resolution, depth and area covering most of the extra-Galactic sky. Here we will present the results of the study carried out by the Euclid Consortium during the period up to the Critical Design Review.

description: In view of the High Luminosity upgrade of the Large Hadron Collider (HL-LHC), planned to start around 2023-2025, the ATLAS experiment will undergo a replacement of the Inner Detector. A higher luminosity will imply higher irradiation levels and hence will demand more ra- diation hardness especially in the inner layers of the pixel system. The n-in-p silicon technology is a promising candidate to instrument this region, also thanks to its cost-effectiveness because it only requires a single sided processing in contrast to the n-in-n pixel technology presently employed in the LHC experiments. In addition, thin sensors were found to ensure radiation hardness at high fluences. An overview is given of recent results obtained with not irradiated and irradiated n-in-p planar pixel modules. The focus will be on n-in-p planar pixel sensors with an active thickness of 100 and 150 um recently produced at ADVACAM. To maximize the active area of the sensors, slim and active edges are implemented. The performance of these modules is investigated at beam tests and the results on edge efficiency will be shown.

description: The emergence of large scale structures in biological systems, and in particular the formation of lines of hierarchy, is observed in many scales, from collections of cells to groups of insects to herds of animals. Motivated by phenomena in chemotaxis and phototaxis, we present a new class of alignment models which exhibit alignment into lines. The spontaneous formation of such ``fingers" can be interpreted as the emergence of leaders and followers in a system of identically interacting agents. Various numerical examples are provided, which demonstrate emergent behaviors similar to the ``fingering'' phenomenon observed in some phototaxis and chemotaxis experiments; this phenomenon is generally known as a challenging pattern to capture for existing models. The novel pairwise interactions provides a fundamental mechanism by which agents may form social hierarchy across a wide range of biological systems.

description: The ambitious instrument suite for the future European Spallation Source whose civil construction started recently in Lund, Sweden, demands a set of diverse and challenging requirements for the neutron detectors. For instance, the unprecedented high flux expected on the samples to be investigated in neutron diffraction or reflectometry experiments requires detectors that can handle high counting rates, while the investigation of sub-millimeter protein crystals will only be possible with large-area detectors that can achieve a position resolution as low as 200 μm. This has motivated an extensive research and development campaign to advance the state-of-the-art detector and to find new technologies that can reach maturity by the time the ESS will operate at full potential. This paper presents the key detector requirements for three of the Time-of-Flight diffraction instrument concepts selected by the Scientific Advisory Committee to advance into the phase of preliminary engineering design. We discuss the available detector technologies suitable for this particular instrument class and their major challenges. The detector technologies selected by the instrument teams to collect the diffraction patterns are briefly discussed. Analytical calculations, Monte-Carlo simulations, and real experimental data are used to develop a generic method to esti- mate the event rate in the diffraction detectors. The proposed approach is based upon conservative assumptions that use information and input parameters that reflect our current level of knowledge and understanding of the ESS project. We apply this method to make predictions for the future diffraction instruments, and thus provide additional information that can help the instrument teams with the optimisation of the detector designs.

description: The recent discovery of long-range magnetic order in atomically thin films has triggered particular interest in two-dimensional (2D) van der Waals (vdW) magnetic materials. In this paper, we perform a systematic theoretical study of the magneto-optical Schäfer-Hubert effect (MOSHE) in 2D vdW antiferromagnetic \textit{M}PS$_3$ (\textit{M} = Mn, Fe, Ni) with multifold intralayer and interlayer magnetic orders. The formula for evaluating the MOSHE in 2D magnets is derived by considering the influence of a non-magnetic substrate. The MOSHE of monolayer and bilayer \textit{M}PS$_3$ are considerably large ($>2^{\circ}$), originating from the strong anisotropy of in-plane optical conductivity. The Schäfer-Hubert rotation angles are surprisingly insensitive to the orientations of the Néel vector, while the Schäfer-Hubert ellipticities are identified to be a good criterion to distinguish different interlayer magnetic orders. Our work establishes a theoretical framework for exploring novel 2D vdW magnets and facilitates the promising applications of the 2D \textit{M}PS$_3$ family in antiferromagnetic nanophotonic devices.

description: The harmonic generation has always been of fundamental interest in studying the nonlinear nature of any physical system. In the present study, Particle - In - Cell (PIC) simulations have been carried out to explore the harmonic generation of Electromagnetic waves in a magnetized plasma. The EM wave propagation is chosen to be parallel to the applied external magnetic field. The simulations show the excitation of odd higher harmonics of RCP (Right circularly polarized) and LCP (Left circularly polarized) when the incident wave is linearly polarised. The harmonic generation is maximum when the incident EM wave frequency matches the electron cyclotron frequency. When the incident EM wave has a circular polarization, no harmonics get excited. A theoretical understanding of these observations has also been provided. The studies thus show that by appropriately tailoring of plasma parameters EM waves of higher frequencies and desired nature of circular polarization can be generated.

description: We propose a geometric method to study the residual symmetries in $N=2$, $d=4$ $\text{U}(1)$ Fayet-Iliopoulos (FI) gauged supergravity. It essentially involves the stabilization of the symplectic vector of gauge couplings (FI parameters) under the action of the U-duality symmetry of the ungauged theory. In particular we are interested in those transformations that act non-trivially on the solutions and produce scalar hair and dyonic black holes from a given seed. We illustrate the procedure for finding this group in general and then show how it works in some specific models. For the prepotential $F=-iX^0X^1$, we use our method to add one more parameter to the rotating Chow-Compère solution, representing scalar hair.

description: The Madison Symmetric Torus (MST) is a toroidal device that, when operated as a tokamak, is resistant to disruptions. Unlike most tokamaks, the MST plasma is surrounded by a close fitting highly conducting wall, with a resistive wall penetration time two orders of magnitude longer than in JET or DIII-D, and three times longer than in ITER. The MST can operate with edge q_a < 2, unlike standard tokamaks. Simulations presented here indicate that the MST is unstable to resistive wall tearing modes (RWTMs) and resistive wall modes (RWMs). They could in principle cause disruptions, but the predicted thermal quench time is much longer than the experimental pulse time. If the MST thermal quench time were comparable to measurements in JET and DIII-D, theory and simulations predict that disruptions would have been observed in MST. This is consistent with the modeling herein, predicting that disruptions are caused by RWTMs and RWMs. In the low q_a regime of MST, the RWTM asymptotically satisfies the RWM dispersion relation. The transition from RWTM to RWM occurs smoothly at q_a = m/n, where m,n are poloidal and toroidal mode numbers.
Exclusive breast feeding, Baby Friendly Hospital Initiative (BFHI), health care providers, infant, Wolaita, Ethiopia

description: Introduction: Promotion of exclusive breastfeeding for the first 6 months of life is the most effective preventive strategy for saving the lives in low-income settings, and significantly contributes to the reduction of child mortality. Baby friendly hospital initiative is based on ten steps to successful breastfeeding; however which one of them are being implemented and associated with exclusive breastfeeding is not clear. Objective: To assess rate of exclusive breastfeeding; Examine whether the health facilities implementing 8 out of ten steps and Identify health facility support factors associated with exclusive breastfeeding. Method and Materials: Community based cross-sectional study was conducted among 458 randomly selected mother-infant pairs and 45 health care providers in town administrations of Wolaita Zone; Southern Ethiopia from January to February 2016. Data were collected from mothers and health care providers using pretested and structured questionnaires. Bivariate and multivariate logistic regressions were performed to identify the presence and strength of association. Odds ratio with 95% confidence interval was estimated to check for statistical significance. Result: The rate of exclusive breastfeeding was (93.2%) and 22.2% of health care providers received training. Facilities demonstrated higher compliance to Step 6, 7 and 9. In multivariate logistic regression; antenatal care visit at government health facility 4.54 (95% CI: 1.77, 11.65), receiving breastfeeding counselling during antenatal care visit 3.05 (95% CI: 1.12, 8.29) and having information on breastfeeding support 3.20 (95% CI: 1.23, 8.33) were statistically significantly association with exclusive breastfeeding. Conclusion: Exclusive breastfeeding rate is high. However, relatively small proportions of managers/staffs trained adequately. Facilities are not complied with majority of baby friendly practices. Attending government health facility for antenatal care visit, receiving breastfeeding counselling during antenatal care visit and having information on breastfeeding support are associated with exclusive breastfeeding practice. These suggest training of managers/staffs, providing support by trained health care providers during antenatal care visit and information on breastfeeding support.

description: We introduce a new version of $ψ$-Hilfer fractional derivative, on an arbitrary time scale. The fundamental properties of the new operator are investigated and, in particular, we prove an integration by parts formula. Using the Laplace transform and the obtained integration by parts formula, we then propose a $ψ$-Riemann-Liouville fractional integral on times scales. The applicability of the new operators is illustrated by considering a fractional initial value problem on an arbitrary time scale, for which we prove existence, uniqueness and controllability of solutions in a suitable Banach space. The obtained results are interesting and nontrivial even for particular choices: (i) of the time scale; (ii) of the order of differentiation; and/or (iii) function $ψ$; opening new directions of investigation.

Shear viscosity of nuclear matter

description: Shear viscosity $η$ is calculated for the nuclear matter described as a system of interacting nucleons with the van der Waals (VDW) equation of state. The Boltzmann-Vlasov kinetic equation is solved in terms of the plane waves of the collective overdamped motion. In the frequent-collision regime, the shear viscosity depends on the particle-number density $n$ through the mean-field parameter $a$, which describes attractive forces in the VDW equation. In the temperature region $T=15 - 40$~MeV, a ratio of the shear viscosity to the entropy density $s$ is smaller than 1 at the nucleon number density $n =(0.5 - 1.5)\,n^{}_0$, where $n^{}_0=0.16\,$fm$^{-3}$ is the particle density of equilibrium nuclear matter at zero temperature. A minimum of the $η/s$ ratio takes place somewhere in a vicinity of the critical point of the VDW system. Large values of $η/s\gg 1$ are, however, found in both the low-density, $n\ll n^{}_0$, and high-density, $n>2n^{}_0$, regions. This makes the ideal hydrodynamic approach inapplicable for these densities.
