Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: Back ground: Breast cancer is the most common cancer in women worldwide. Approximately 1.7 million new cases were recorded globally in 2012, accounting for 25 percent of all new cases of cancer in women. Because of an increased vulnerability to breast cancer there is increasing comorbid conditions at the time of diagnosis. Comorbidity is an illness other than the principal diagnosis that influences the outcome of treatment. The number of comorbidities per individual patient ranged from none to 13. Objective: To assess comorbidities and associated factors among breast cancer patients who have been treated and made follow up in Tikur Anbesa Hospital, Addis Ababa, Ethiopia Methods: A facility based cross-sectional study design was employed among a total of 404 randomly selected breast cancer patients who had follow up in Tikur Anbesa Referral Hospital. Every other patient who came for follows ups were interviewed and their charts were tracked and reviewed to assess comorbidities following their interview. The interview was done immediately following their medical checkup and the sequences of the interview was based on their medical checkup. A semi structured questionnaire prepared in English and translated to Amharic language from June to August 2017 was employed. Frequency, cross tabulation, Logistic regression applied to calculate percentage, 95% CI and Odds Ratio with SPSS version 20.0 after cleaned and edited. Result: In this study a total of 404 female breast cancer cases were assessed of which the mean and SD, age of the study participants was 43.5+7.8 years respectively. Of all study participants 322 (79.7 %) were have comorbidities. Fatty liver 48(11.9%), Neutropenia 43 (10.6%), Gastritis/PUD 34 (8.4%), Anemia 31 (7.7%) were top listed or more prevalent comorbidities in the first and second follow up times. Participants who were not under radiation treatment were 0.37 times less odds to develop comorbidity than under those who were under radiation treatment, OR 0.37, 95% CI (0.19-0.72) and those who did not get hormone treatment were 0.26 times less chance than those who got hormone treatment, OR 0.26, 95% CI (0.16-0.74). Conclusion and Recommendation: Large number of breast cancer patients had comorbidities. Attention should be given during patient's diagnosis not to distract breast cancer and comorbidity one with the other, develop system to identify number of comorbidities which used to use the data for action and, Neutropenia, Fatty liver, Gastritis, Anemia were with the highest prevalent comorbidities especially during the first and second follow up of the breast cancer patients so attention shall be given how to management of them.

description: Sagan et al. (1993) used the Galileo space probe data and first principles to find evidence of life on Earth. Here we ask whether Sagan et al. (1993) could also have detected whether life on Earth had three-dimensional structure, based on the Galileo space probe data. We reanalyse the data from this probe to see if structured vegetation could have been detected in regions with abundant photosynthetic pigments through the anisotropy of reflected shortwave radiation. We compare changing brightness of the Amazon forest (a region where Sagan et al. (1993) noted a red edge in the reflectance spectrum, indicative of photosynthesis) as the planet rotates to a common model of reflectance anisotropy and found measured increase of surface reflectance of 0.019 versus a 0.007 predicted from only anisotropic effects. We hypothesize the difference was due to minor cloud contamination. However, the Galileo dataset had only a small change in phase angle (sun-satellite position) which reduced the observed anisotropy signal and we demonstrate that theoretically if the probe had a variable phase angle between 0-20, there would have been a much larger predicted change in surface reflectance of 0.06 and under such a scenario three-dimensional vegetation structure on Earth could possibly have been detected. These results suggest that anisotropic effects may be useful to help determine whether exoplanets have three-dimensional vegetation structure in the future but that further comparisons between empirical and theoretical results are first necessary.

description: Gravitational-wave (GW) radiation from a coalescing compact binary is a standard siren as the luminosity distance of each event can be directly measured from the amplitude of the signal. One possibility to constrain cosmology using the GW siren is to perform statistical inference on a population of binary black hole (BBH) events. In essence, this statistical method can be viewed as follows. We can modify the shape of the distribution of observed BBH events by changing cosmological parameters until it eventually matches the distribution constructed from an astrophysical population model, thereby allowing us to determine the cosmological parameters. In this work, we derive the Cramér-Rao bound for both cosmological parameters and those governing the astrophysical population model from this statistical dark siren method by examining the Fisher information contained in the event distribution. Our study provides analytical insights and enables fast yet accurate estimations of the statistical accuracy of dark siren cosmology. Furthermore, we consider the bias in cosmology due to unmodeled substructures in the merger rate and the mass distribution. We find a $1\%$ deviation in the astrophysical model can lead to a more than $1\%$ error in the Hubble constant. This could limit the accuracy of dark siren cosmology when there are more than $10^4$ BBH events detected.

description: We design plano-concave silicon lenses with coupled gradient-index plasmonic metacoatings for ultrawide apertured focusing utilizing a reduced region of $\sim 20 λ^2$. The anomalous refraction induced in the planar input side of the lens and in the boundary of the wavelength-scale focal region boosts the curvature of the emerging wavefront, thus significantly enhancing the resolution of the tightly-focused optical wave. The formation of a light tongue with dimensions approaching those of the concave opening is here evidenced. This scheme is expected to have potential applications in optical trapping and detection.

description: In this article, we study the ground states and the first radial excited states of the tensor-tensor type scalar hidden-charm tetraquark states with the QCD sum rules. We separate the ground state contributions from the first radial excited state contributions unambiguously, and obtain the QCD sum rules for the ground states and the first radial excited states, respectively. Then we search for the Borel parameters and continuum threshold parameters according to four criteria and obtain the masses of the tensor-tensor type scalar hidden-charm tetraquark states, which can be confronted to the experimental data in the future.

description: Low achei vements in the Expanded Programme on Immunization (EPI) has been found to be one of the major health problems in the North-Eastern Arsi region of Ethiopia. This study was conducted to assess fact ors having influence on the attainment of EPI rates at the level of individual health care units. The factors studied were categorized as follows: a) Factors related to the health workers' knowledge, attitude and practice. b) Factors related to the the health care delivery system, with emphasis on the provision of EPI service. c) Factors related to the char acteristics of the health care uni ts, and d) factors related to the socio-cul tural, demographic and other characteristics of mothers. Two health workers from each one of the 17 health care units were included in the study population and from the area serviced by each health care unit, 50 mothers of undertwo children were selected . The study found that the immunization coverage rates attained by the individual health care units ranged from 18% to 96%. In the case of pregnant women the rate ranged from 12% to 96%. The mean immunization rates were 52.8% and 51% in the under-two children and pregnant mothers, respectively. other findings were that daily EPI session, using occasions of mass meetings or other public gatherings for informing the public about EPI, weekly tracing of EPI defaulters, vi and involving the community in EPI activities were found to be associated with high coverage. Mothers' educational status, attitude towards the health care system, and EPI, were positively associated with immunization coverage.

description: We examine the precision limits of Hong-Ou-Mandel (HOM) timing measurements, as well as precision limits applying to generalized two-photon measurements. As a special case, we consider the use of two-photon measurements using photons with variable bandwidths and frequency correlations. When the photon bandwidths are not equal, maximizing the measurement precision involves a trade-off between high interference visibility and strong frequency anticorrelations, with the optimal precision occuring when the photons share non-maximal frequency anticorrelations. We show that a generalized measurement has precision limits that are qualitatively similar to those of the HOM measurement whenever the generalized measurement is insensitive to the net delay of both photons. By examining the performance of states with more general frequency distributions, our analysis allows for engineering of the joint spectral amplitude for use in realistic situations, in which both photons may not have ideal spectral properties.

description: The Herbig Ae/Be stars (HAeBes) allow an exploration of the properties of Pre-Main Sequence(PMS) stars above the low-mass range ($<2{\rm\thinspace M_{\odot}}$) and those bordering the high-mass range ($>8{\rm\thinspace M_{\odot}}$). This paper is the second in a series exploring accretion in 91 HAeBes with Very Large Telescope/X-shooter spectra. Equivalent width measurements are carried out on 32 different lines, spanning the UV to NIR, in order to obtain their line luminosities. The line luminosities were compared to accretion luminosities, which were determined directly from measurements of an UV-excess. When detected, emission lines always demonstrate a correlation with the accretion luminosity, regardless of detection frequency. The average relationship between accretion luminosity and line luminosity is found to be ${\thinspace L_{\rm acc}}\propto{\thinspace L_{\rm line}}^{1.16 \pm 0.15}$. This is in agreement with the findings in Classical T Tauri stars, although the HAeBe relationship is generally steeper, particularly towards the Herbig Be mass range. Since all observed lines display a correlation with the accretion luminosity, all of them can be used as accretion tracers. This has increased the number of accretion diagnostic lines in HAeBes tenfold. However, questions still remain on the physical origin of each line, which may not be due to accretion.

Creators: name: Dendir, Andamlak
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: Globally, malnutrition is one of the most common causes of morbidity and mortality in children under the age of five year. In our nation 51% of all causes of death in children under the age of five year were associated with malnutrition. But, little information is available on whether maternal empowerment and food insecurity are contextual underlying determinants of protein energy malnutrition among 6-36 month old children, especially in the case of gurage zone. Therefore, this study aimed to assess the relationship between household maternal empowerment and food security status on protein energy malnutrition (PEM) among 6-36 month old children Methods: A health facility based unmatched case–control study was conducted from February 20 to April 20, 2015 among 6-36 month old children who visited to Butajira hospital and health center in Butajira town of Gurage zone. A total of 346 (116 children with undernutrition and 232 children free of undernutrition) children were included in the study. Though eligible case participants were selected consecutively, control participants were selected by systematic sampling technique. The data were collected using interviewer administered structured questionnaire with anthropometric measurement instrument. Data were entered into EPI data 3.1 computer program and analyzed using statistical package for social science version 21. Crude and adjusted odds ratios were calculated through simple and binominal multiple logistic regressions model. Result:-A total of 115 cases and 231 controls were included in the analysis. After adjusting for the potential confounders, stunting among children was significantly associated with household maternal disempowermentAOR 6.66 (2.32-19.14), moderateAOR 4.894 (1.66-14.35) and severe food insecurity AOR 9.465 (3.13-28.57). Sever food insecurity AOR 2.880 (1.282-6.469) and maternal disempowermentAOR 2.658 (1.067-6.621) was significantly associated with Underweight. However, from hypothesized variables only sever food insecurity were shown an association with wastingAOR 2.79 (1.09-7.16) Conclusion: Maternal disempowerment and severe food insecurity were independently associated with wasting, stunting and underweight among 6-36 month old children who visited to Butajira Hospital and Health center of Gurage zone. Besides, living in rural residence, having low wealth status and being in age group less than or equal to 24month were found to be factor influencing the nutritional status of children.

description: We present the results from the analysis of galaxy rotation curves with Verlinde's emergent gravity. We use the data in the SPARC (Spitzer Photometry and Accurate Rotation Curves) database, which contains a sample of 175 nearby disk galaxies with 3.6 $μ$m surface photometry and rotation curves. We compute the gravitational acceleration at different galactocentric radii expected from the baryon distribution of the galaxies with the emergent gravity, and compare it with the observed gravitational acceleration derived from galactic rotation curves. The predicted and observed accelerations agree well with a mean offset $μ{\rm [log(g_{obs})-log(g_{Ver})]}=-0.060\pm0.004$ and a scatter $σ{\rm [log(g_{obs})-log(g_{Ver})]}=0.137\pm0.004$ by assuming a de Sitter universe. These offset and scatter become smaller when we assume a more realistic universe, quasi de Sitter universe, as $μ=-0.027\pm0.003$ and $σ=0.129\pm0.003$. Our results suggest that Verlinde's emergent gravity could be a good solution to the missing mass problem without introducing dark matter.

description: We use the local value of the Hubble constant recently measured with 2.4% precision, as well as the latest compilation of cosmic chronometers data, together with standard probes such as Supernovae Type Ia and Baryon Acoustic Oscillation distance measurements, in order to impose constraints on the viable and most used f(T) gravity models, where T is the torsion scalar in teleparallel gravity. In particular, we consider three f(T) models with two parameters, out of which one is independent, and we quantify their deviation from $Λ$CDM cosmology through a sole parameter. Our analysis reveals that for one of the models a small but non-zero deviation from $Λ$CDM cosmology is slightly favored, while for the other models the best fit is very close to $Λ$CDM scenario. Clearly, f(T) gravity is consistent with observations, and it can serve as a candidate for modified gravity.

description: Ferroelectricity in atomically thin bilayer structures has been recently predicted1 and measured[2-4] in two-dimensional (2D) materials with hexagonal non-centrosymmetric unit-cells. Interestingly, the crystal symmetry translates lateral shifts between parallel 2D layers to a change of sign in their out-of-plane electric polarization, a mechanism referred to as "Slide-Tronics"[4]. These observations, however, have been restricted to switching between only two polarization states under low charge carrier densities[5-12], strongly limiting the practical application of the revealed phenomena[13]. To overcome these issues, one needs to explore the nature of the polarization that arises in multi-layered van der Waals (vdW) stacks, how it is governed by intra- and inter-layer charge redistribution, and to which extent it survives the introduction of mobile charge carriers, all of which are presently unknown14. To explore these questions, we conduct surface potential measurements of parallel WSe2 and MoS2 multi-layers with aligned and anti-aligned configurations of the polar interfaces. We find evenly spaced, nearly decoupled potential steps, indicating highly confined interfacial electric fields, which provide means to design multi-state "ladder ferroelectrics". Furthermore, we find that the internal polarization remains significant upon electrostatic doping of a mobile charge carrier density as high as 1013 cm-2, with substantial in-plane conductivity. Using first-principles calculations based on density functional theory (DFT), we trace the extra charge redistribution in real and momentum space and identify an eventual doping-induced depolarization mechanism.

I describe here the logical and historical construction of this theory, by emphasising the pioneering and key role it played for neutrino mass. I show that it is a self-contained and predictive model with the Higgs origin of Majorana neutrino mass, in complete analogy with the SM situation regarding charged fermions.

description: Quantized vortices are the prototypical feature of superfluidity. Pervasive in all natural systems, vortices are yet to be observed in dipolar quantum gases. Here, we exploit the anisotropic nature of the dipole-dipole interaction of a dysprosium Bose-Einstein condensate to induce angular symmetry breaking in an otherwise cylindrically symmetric pancake-shaped trap. Tilting the magnetic field towards the radial plane deforms the cloud into an ellipsoid through magnetostriction, which is then set into rotation. At stirring frequencies approaching the radial trap frequency, we observe the generation of dynamically unstable surface excitations, which cause angular momentum to be pumped into the system through vortices. Under continuous rotation, the vortices arrange into a stripe configuration along the field--in close corroboration with simulations--realizing a long sought-after prediction for dipolar vortices.

description: In this paper we show that the equation of motion of a massless scalar particle near the black hole (BH) horizon in the Schwarzschild-deSitter (SdS) spacetime enjoys a hidden conformal symmetry when the two horizons satisfy a quadratic relation, not related with the Nariai limit. This hidden symmetry is $SL(2,\mathbb{R})\times SO(2)$ instead of $SO(2,1)\times SO(2)$, the expected symmetry of $dS_2\times S^2$. We present a structural analysis of SdS spacetime and compute the leading quantum corrections to the entropy of SdS spacetime in a semi-classical way.

description: Climate change has a crucial impact on European agriculture in plenty of ways. The role of land use systems, such as agriculture, as a climate change mitigation and adaptation strategy is important as these systems can collect atmospheric carbon dioxide (CO2) and store carbon (C). Although biomass carbon storage in agriculture has been highly neglected. The methodological difficulties in estimating the C stock of biomass and soil storage of Carbon are reinforced by the lack of reliable estimates of the agriculture area. This research analyses the relationship between changes in tree cover in agricultural areas of the Mediterranean area (more specifically in the regions of Spain, Italy and Greece) and the storage of biomass carbon (associated with the related mitigation of CO2 emissions). Remote sensing images have become a valuable source of data for this analysis. Α set of remote sensing data with MODIS satellite images was used and was combined with Tier 1 carbon storage estimates to estimate carbon dioxide storage for the Mediterranean climate zones. The measurements for biomass carbon were made at the overall level for the Mediterranean but also separately for the national and regional levels of Italy, Greece and Spain. The findings of the research showed that the distribution of tree cover in agricultural areas widely followed the climatic zones. Most part of the agricultural land in Europe is estimated at levels around 10 t C / ha.

description: It has been realized that thermal shear plays a similar role as thermal vorticity in polarizing spin of particles in heavy ion collisions. We point out that shear has a fundamental difference that it leads to particle redistribution in the medium. The redistribution gives rise to an additional contribution to spin polarization through the self-energy, which is parametrically the same order as the one considered so far in the literature. The self-energy contribution is in general gauge dependent. We introduce double gauge links stretching along the Schwinger-Keldysh contour to restore gauge invariance. We also generalize the straight path to adapt to the Schwinger-Keldysh contour. We find another contribution associated with the gauge link, which is also parametrically the same order. We illustrate the two contributions with a massive probe fermion in massless QED plasma with shear. A modest suppression of spin polarization is found from the combined contributions when the probe fermion has momentum much greater than the temperature.

description: We performed a spectral line survey called Exploring Molecular Complexity with ALMA (EMoCA) toward Sagittarius~B2(N) between 84.1 and 114.4 GHz with the Atacama Large Millimeter/submillimeter Array (ALMA) in its Cycles 0 and 1. We determined line intensities of n-propyl cyanide in the ground vibrational states of its gauche and anti conformers toward the hot molecular core Sagittarius B2(N2) which suggest that we should also be able to detect transitions pertaining to excited vibrational states. We wanted to determine spectroscopic parameters of low-lying vibrational states of both conformers of n-propyl cyanide to search for them in our ALMA data. We recorded laboratory rotational spectra of n-propyl cyanide in two spectral windows between 36 and 127 GHz. We searched for emission lines produced by these states in the ALMA spectrum of Sagittarius B2(N2). We modeled their emission and the emission of the ground vibrational states assuming local thermodynamic equilibrium (LTE). We have made extensive assignments of a- and b-type transitions of the four lowest vibrational states of the gauche conformer which reach J and Ka quantum numbers of 65 and 20, respectively. We assigned mostly a-type transitions for the anti conformer with J and Ka quantum numbers up to 48 and 24, respectively. Rotational and Fermi perturbations between two anti states allowed us to determine their energy difference. The resulting spectroscopic parameters enabled us to identify transitions of all four vibrational states of each conformer in our ALMA data. The emission features of all states, including the ground vibrational state, are well-reproduced with the same LTE modeling parameters, which gives us confidence in the reliability of the identifications, even for the states with only one clearly detected line.

Tsallis cosmology and its applications in dark matter physics with focus on IceCube high-energy neutrino data

description: In this paper we employ a recent proposal of C. Tsallis and formulate the first law of thermodynamics for gravitating systems in terms of the extensive but non-additive entropy. We pay a particular attention to an integrating factor for the heat one-form and show that in contrast to conventional thermodynamics it factorizes into thermal and entropic part. Ensuing first law of thermodynamics implies Tsallis cosmology, which is then subsequently used to address the observed discrepancy between current bound on the Dark Matter relic abundance and present IceCube data on high-energy neutrinos. To resolve this contradiction we keep the conventional minimal Yukawa-type interaction between standard model and Dark Matter particles but replace the usual Friedmann field equations with Tsallis-cosmology-based modified Friedmann equations. We show that when the Tsallis scaling exponent $δ\sim 1.57$ (or equivalently, the holographic scaling exponent $α\sim 3.13$) the aforementioned discrepancy disappears.

Molecular Lines of 13 Galactic Infrared Bubble Regions

description: We investigated the physical properties of molecular clouds and star formation processes around infrared bubbles which are essentially expanding HII regions. We performed observations of 13 galactic infrared bubble fields containing 18 bubbles. Five molecular lines, 12CO (J=1-0), 13CO (J=1-0), C18O(J=1-0), HCN (J=1-0), and HCO+ (J=1-0), were observed, and several publicly available surveys, GLIMPSE, MIPSGAL, ATLASGAL, BGPS, VGPS, MAGPIS, and NVSS, were used for comparison. We find that these bubbles are generally connected with molecular clouds, most of which are giant. Several bubble regions display velocity gradients and broad shifted profiles, which could be due to the expansion of bubbles. The masses of molecular clouds within bubbles range from 100 to 19,000 solar mass, and their dynamic ages are about 0.3-3.7 Myr, which takes into account the internal turbulence pressure of surrounding molecular clouds. Clumps are found in the vicinity of all 18 bubbles, and molecular clouds near four of these bubbles with larger angular sizes show shell-like morphologies, indicating that either collect-and-collapse or radiation-driven implosion processes may have occurred. Due to the contamination of adjacent molecular clouds, only six bubble regions are appropriate to search for outflows, and we find that four of them have outflow activities. Three bubbles display ultra-compact HII regions at their borders, and one of them is probably responsible for its outflow. In total, only six bubbles show star formation activities in the vicinity, and we suggest that star formation processes might have been triggered.

Nonlocal de Sitter gravity and its exact cosmological solutions

description: This paper is devoted to a simple nonlocal de Sitter gravity model and its exact vacuum cosmological solutions. In the Einstein-Hilbert action with $Λ$ term, we introduce nonlocality by the following way: $R - 2 Λ= \sqrt{R-2Λ}\ \sqrt{R-2Λ} \to \sqrt{R-2Λ}\ F(\Box)\ \sqrt{R-2Λ} ,$ where ${F} (\Box) = 1 + \sum_{n= 1}^{+\infty} \big( f_n \Box^n + f_{-n} \Box^{-n} \big) $ is an analytic function of the d'Alembert-Beltrami operator $\Box$ and its inverse $\Box^{-1}$. By this way, $R$ and $Λ$ enter with the same form into nonlocal version as they are in the local one, and nonlocal operator $F(\Box)$ is dimensionless. The corresponding equations of motion for gravitational field $g_{μν}$ are presented. The first step in finding some exact cosmological solutions is solving the equation $\Box \sqrt{R-2Λ} = q \sqrt{R-2Λ} , $ where $ q =ζΛ\quad (ζ\in \mathbb{R})$ is an eigenvalue and $\sqrt{R-2Λ}$ is an eigenfunction of the operator $\Box .$ We presented and discussed several exact cosmological solutions for homogeneous and isotropic universe. One of these solutions mimics effects that are usually assigned to dark matter and dark energy. Some other solutions are examples of the nonsingular bounce ones in flat, closed and open universe. There are also singular and cyclic solutions. All these cosmological solutions are a result of nonlocality and do not exist in the local de Sitter case.

description: This study aims to unravel the mechanism of colossal magnetoresistance (CMR) observed in n-type HgCr$_2$Se$_4$, in which low-density conduction electrons are exchange-coupled to a three-dimensional Heisenberg ferromagnet with a Curie temperature $T_C\approx$ 105 K. Near room temperature the electron transport exhibits an ordinary semiconducting behavior. As temperature drops below $T^*\simeq2.1T_C$, the magnetic susceptibility deviates from the Curie-Weiss law, and concomitantly the transport enters an intermediate regime exhibiting a pronounced CMR effect before a transition to metallic conduction occurs at $T

description: We consider the frog model with geometric lifetime (parameter $1-p$) on homogeneous trees of dimension $d$. In 2002, \cite{alves2002-2} proved that there exists a critical lifetime parameter $p_c\in(0,1)$ above which infinitely many frogs are activated with positive probability, and they gave lower and upper bounds for $p_c$. Since then, the literature on this model focussed on refinements of the upper bound. In the present paper we improve the bounds for $p_c$ \emph{on both sides}. We also provide a discussion comparing the bounds of the literature and their proofs. Our proofs are based on coupling.
