description: Deep learning has emerged as an effective solution for addressing the challenges of short-term voltage stability assessment (STVSA) in power systems. However, existing deep learning-based STVSA approaches face limitations in adapting to topological changes, sample labeling, and handling small datasets. To overcome these challenges, this paper proposes a novel phasor measurement unit (PMU) measurements-based STVSA method by using deep transfer learning. The method leverages the real-time dynamic information captured by PMUs to create an initial dataset. It employs temporal ensembling for sample labeling and utilizes least squares generative adversarial networks (LSGAN) for data augmentation, enabling effective deep learning on small-scale datasets. Additionally, the method enhances adaptability to topological changes by exploring connections between different faults. Experimental results on the IEEE 39-bus test system demonstrate that the proposed method improves model evaluation accuracy by approximately 20% through transfer learning, exhibiting strong adaptability to topological changes. Leveraging the self-attention mechanism of the Transformer model, this approach offers significant advantages over shallow learning methods and other deep learning-based approaches.

Year: 2014

description: Background: Substance abuse during pregnancy is more prevalent than commonly realized.The problem is greatly underestimated in many parts of the world. Specifically limited research to date has addressed the relationship between substance use and birth outcomes among women in Ethiopia. Therefore, the study to close the gap in generating first hand information on the issue Objective: The main objective of this study was to examine the effect of maternal substance abuse on the birth weight of a newborn Methods: The study used analytic study method in the form of facility based unmatched case control study, which compares the substance use of women during pregnancy with birth weight of newborns delivered from women in Addis Ababa Hospitals using an interview with a structured and pre-tested questionnaire. Sample total sample was allocated to each health facility based on their patient load by proportionate to size, and a total of 112 cases of neonates with low birth weight were compared with 235 controls of neonates born with normal or higher birth weight to identify gaps. The data were analyzed using the SPSS-21 statistical - package. Results:- khat chewing, cigarette and shisha smoking and having a partner smoking during pregnancy were statistically significant with lower birth weight Overall, factors associated with low birth weight were mothers who had sexual violence during pregnancy, Mothers who did not attend primary school (Education) and those with history of low birth weight. Moreover, lesser weight gain during pregnancy and short birth interval were associated with low birth weight. Conclusion:- The association of low birth weight among mothers who had substance abuse was strong for particularly khat, cigarette and shisha smoking during pregnancy therefore, I recommend health professionals working in antenatal care service should be given training on counseling of mothers for banning or lowering use of substance abuse, and providing educational opportunity for girls and mothers is needed.

description: An der Modellegierung Fe-15%Cr wurden Anfangszustände der Oxidation untersucht, wie sie sich einerseits aus dem Angriff der Probenoberfläche durch O2 unter Ultrachochvakuum-Bedingungen (UHV) und andererseits in strömenden Gasgemischen N2/Ar-H2-H2O bei Atmosphärendruck ergeben. Verschieden orientierte Einkristallproben ((100), (110) und (111)) wurden zum Teil bereits nach mechanischer Präparation für eine Minute bei 800°C in einem Hochtemperatur-Reaktor oxidiert, der im Wesentlichen einem Röhrenofen entspricht aber direkten Zugang zur oberflächenanalytischen Untersuchung mittels Röntgen-Photoelektronen-Spektroskopie (XPS) bietet. Teils wurden die Proben ebenfalls bei 800°C in entsprechenden Dosen Sauerstoff [mbar·s] in der Präparationskammer einer UHV-Apparatur oxidiert und deren Ergebnisse miteinander verglichen. Darüber hinaus war es möglich, den Fortschritt der Oxidation der Probenoberfläche bei kleinem Sauerstoffdruck und bis zu 440°C in einem Rastertunnelmikroskop (STM) in-situ zu verfolgen. Es konnte gezeigt werden, daß trotz des großen Druckunterschieds geeignete Bedingungen gefunden werden können, unter denen der Oxidationsangriff vergleichbare Schichtdicken und Oxidstrukturen zur Folge hat, obwohl sich das Verhalten der verschiedenen Probenorientierungen deutlich voneinander unterscheidet.

description: Detections of extended Ly$α$ halos (LAHs) around Ly$α$ emitters (LAEs) have lately been reported on a regular basis, but their origin is still under investigation. Simulation studies predict that the outer regions of the extended LAHs contain a major contribution from the Ly$α$ emission of faint, individually undetected LAEs. To address this matter from an observational angle, we use halo occupation distribution (HOD) modeling to reproduce the clustering of a spectroscopic sample of 1265 LAEs at $3

description: We compute the transverse single spin asymmetry in light hadron production $p^\uparrow p\to hX$ and $p^\uparrow A\to hX$ including the gluon saturation effect in the unpolarized nucleon/nucleus. In the forward (large-$x_F$) region, the dominant contribution comes from the so-called derivative term associated with the soft gluonic pole. This leads to the cancellation of nuclear effects in $A_N$ which can be tested at RHIC. We also show that the soft fermionic pole disappears in the saturation environment.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: New adverse events and toxicities are identified as people live longer on ART and the availability of numerous new drugs and drug combinations make systematic monitoring of ADR critical in the HIV program. The contribution of health professionals to adverse drug reaction databases is enormously significant, but under-reporting remains a major draw-back of spontaneous reporting and the level of adverse drug reaction reporting in Ethiopia is alarmingly low. Thus, a facility based cross sectional study was conducted in ART clinics of public health facilities of Addis Ababa city to assess the health care providers' knowledge, attitude & practice on adverse drug reaction reporting. A total of 250 health care providers were included in the study by considering a 10% nonresponse rate. Using proportional allocation to type of facilities; 9 facilities from Public hospitals and 27 from health center based ART clinics were selected. Data was collected through a selfadministered questionnaire from health professionals selected by simple random sampling methods. Observation was also used to verify existence of reporting forms in the facilities. After the data collection was completed, data was entered and processed using EPI-info software and exported to SPSS for analysis. The response rate was 93.22%. Among respondents (108)46.2% were aware of the existence of a national Pharmacovigilance center in Ethiopia and only 92(39.3%) of them knew where it is located. Among the respondents only 134(57.3 %) of them were aware of the yellow card reporting scheme for reporting ADRs. Most respondents 208 (88.9%) agree the fact that ADR should be reported spontaneously at a regular basis. 212(92.7%) of them also agree that reporting ADR is part of their duty as health professionals & 197(84.2%) of the respondents believe that reporting ADR should be mandatory. 101 (43. 2%) of the respondents encountered at least one patient on ADR in their clinical practice in the past one year and 96(41%) of the respondents encountered at least one ADR on PLWHAs taking ART. But only 31(30.7%) of the respondents reported that they noted the ADR they encountered on patient clinical or pharmacy record and only 34(14.5%) of the respondents had ever reported ADRs. The present study revealed the health care professionals have positive attitudes towards ADR monitoring and reporting. But there are gaps in knowledge and practice of ADR reporting. The major reasons for under reporting are found to be concern that the report may be wrong, lack of confidence on diagnosis of ADR and unavailability of reporting forms.

description: Objectives: This study was aimed to determine the magnitude and associated risk factors of low back pain among taxi drivers in Addis Ababa, Ethiopia. Methods: A cross sectional study was conducted among 422 full time taxi drivers from February to May 2015. The data were collected using questionnaire adapted from Nordic questionnaire. The questionnaire included questions about socio demographic variables, work-related, lifestyle activity and psychosocial characteristics. Prevalence of LBP was assessed as frequencies of study subject those response experiences of LBP and the data were obtained using an interview questionnaire. Bivariate analysis was used to assess the association between these variables and Multivariate analysis to control confounding variables. Results: Prevalence of LBP was found to be 64.2%. The study found year of driving, history of back trauma, frequent load lifting, lack of rest break during work day, uncomfortable seat pan and previous job involve sitting as risk factors for LBP among taxi drivers in this study. LBP was associated significantly with history of back trauma (OR=4.014, 95% CI 2.329-6.916, p<0.001), driving for more than nine year duration (OR=3.668, 95% CI 1.376-10.859, p=0.01). Ergonomics factors like uncomfortable seat pan (OR=1.73, 95% CI 1.08-2.77, p=0.023), lack of rest break during work day (OR=1.906,95% CI 1.179-3.08, p=0.008), characteristics of previous job involve sitting (OR=2.972, 95% CI 1.79-4.932, p<0.001), frequently load handling activity at work (OR=2.13, 95% CI 1.045-4.344, p= 0.039) were found risk factors of LBP among taxi drivers in this present study. Conclusion: These findings call for preventive strategies and safety guidelines, in order to reduce the incidence of LBP, among taxi drivers in, Addis Ababa, Ethiopia.
Physikalische Grundlagen von chemischen Raman-Sensoren mit Schwerpunkt auf faseroptischen SERS-Sonden

description: Faseroptische SERS-Sensoren wurden durch die Beschichtung der Endflächen von optischen Fasern mit rauhen Metallfilmen erzeugt. Zu den verschiedenen Präparationstechniken, die angewendet und verglichen wurden, gehörten das langsame Aufdampfen von Metall-Inselfilmen und das Bedampfen von Nanopartikeln, aufgerauhten oder elektronenlithographisch strukturierten Oberflächen mit Metallfilmen. Der Einfluß der Laserleistung auf die Messungen mit SERS-Sensoren wurde untersucht, und es wurden maximale Laserintensitäten bestimmt, oberhalb derer es zu einer Verringerung der Oberflächenverstärkung kommt.Aufgrund der Überlagerung der SERS-Spektren von der Faserspitze und der Raman-Spektren des Faserkernmaterials sind maximale Oberflächenverstärkungen eine Voraussetzung für die Konstruktion langer Fasersensoren. Die Oberflächenverstärkung konnte durch eine Veränderung der Fasersensorgeometrie deutlich verbessert werden, wobei diese Geometrieänderung durch gewinkeltes Anschleifen und konisches Ätzen erzeugt wurde.Die Anwendbarkeit der faseroptischen SERS-Sensoren als chemische Sensoren wurde anhand von Beschichtungen mit selektiv adsorbierenden Rezeptormolekülen untersucht.
description: Single-fibre sensors using surface-enhanced Raman-scattering were prepared by depositing rough metal films at the tips of optical fibres. Different deposition techniques such as slow evaporation of metal island films and vacuum deposition of metal films over nanoparticles or on pre-roughened surfaces or on surfaces structured by electron beam lithography were applied and compared. Laser power effects on SERS sensors were investigated and maximum laser intensities were determined above which a reduction of SERS enhancement is indicated. The superposition of surface Raman spectra from the tips and Raman spectra of the fibre core made maximum enhancements necessary for the construction of long fibre sensors. The enhancement was improved significantly by altering the tip geometry (using angled polishing and conical etching). The applicability of SERS-active fibre tips as chemical sensors was investigated by coating them with selectively adsorbing receptor molecules.

description: We investigate a non-Hermitian model featuring non-reciprocal gradient hoppings. Through an in-depth analysis of the Liouvillian spectrum and dynamics, we confirm the emergence of the Liouvillian skin effect resulting from the non-reciprocal nature of hoppings in this model. Furthermore, we observe that the presence of gradient hopping strength leads to an accelerated relaxation time for the system. Through numerical investigations of the Liouvillian gap, relaxation time, and steady-state localization length, we discover that the relaxation time in this model cannot be explained by the currently established relationship associated with the Liouvillian skin effect. This discrepancy highlights the need for further exploration and theoretical advancements to fully comprehend the intricate mechanisms underlying quantum relaxation processes. Motivated by these findings, we propose a theoretical approach to realize this non-Hermitian model in an atomic system with a sideband structure by employing adiabatic elimination technique. These results contribute to our deeper comprehension of quantum relaxation dynamics and provide theoretical backing for the development of techniques aimed at controlling quantum relaxation processes.

description: We consider a particle trapped by a generic external potential and under the influence of a quantum-thermal Ohmic bath. Starting from the Langevin equation, we derive the corresponding Schwinger-Keldysh action. Then, within the path-integral formalism, we obtain both the semiclassical Fokker-Planck equation and the quantum Fokker-Planck equation for this out-of-equilibrium system. In the case of an external harmonic potential and in the underdamped regime, we find that our Fokker-Planck equations contain an effective temperature $T_{\rm eff}$, which crucially depends on the interplay between quantum and thermal fluctuations in contrast to the classical Fokker-Planck equation. In the regime of high temperatures, one recovers the classical Fokker-Planck equation. As an application of our result, we also provide the stationary solution of the semiclassical Fokker-Planck equations for a superconducting Josephson circuit and for a Bose Josephson junction, which are experimentally accessible.

Creators: name: Abraham, Zinash
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Background- Addressing family planning in the postpartum period is crucial for better maternal, neonatal and child survival because it enables women to achieve healthy interval between births. The first year after a woman has given birth is crucial for use of contraceptives to prevent unwanted pregnancy. Many women, however, do not realize that they are at a risk for pregnancy during this period. Consequently, contraceptive use by women during this period is low, resulting to unintended pregnancies and unwanted childbearing. Objectives -To assess intention and determinants of contraceptive use among postpartum married women in health centers of Adama. Method- - A facility based cross sectional study that employed exit interviews with postnatal clients was conducted in all public health centers, from June –July, 2016 in Adama town. Four hundred twenty two study subjects were allocated to the institution by proportional based on the number of deliveries three months prior to the study. Pre tested structured Amharic version questionnaire was used to collect the data through interview. Both bivariate and multiple logistic regressions were used to identify determinant factors. Result -Of 420 postnatal women interviewed 66.2% of them were intention to use contraceptive methods and 45.5% postnatal mothers stated that they have an intention to start after 45 days of delivery. However, 43.6% of respondents have negative attitude towards modern contraceptive. Governmental Occupation, Desire for more children, Frequency of ANC visit and discussion with providers after delivery were the main determinants of the intention to use postpartum family planning among the mothers (AOR of 3.029; 95%CI (1.19, 7.70), AOR of 0.45; 95%CI (0.24, 0.84)), AOR of 0.42; 95%CI (0.20, 0.85) and AOR of 2.98; 95% CI of (1.84, 4.82)) respectively. Conclusion and Recommendation-This study has revealed that intention to use contraceptive during post partum period is significantly higher. Family planning programmes should give high priority to the mothers in order to encourage them uptake contraceptives as early as possible during their postpartum period. Likewise, there is need to strengthen policies that promote girls education and opportunity of job. Health professional should discuss about FP after delivery and during consecutive antenatal visit is crucial to improve contraceptive knowledge and empower women to make informed choice
A Two-Stage Active-Set Algorithm for Bound-Constrained Optimization

description: In this paper, we describe a two-stage method for solving optimization problems with bound constraints. It combines the active-set estimate described in [Facchinei and Lucidi, 1995] with a modification of the non-monotone line search framework recently proposed in [De Santis et al., 2012]. In the first stage, the algorithm exploits a property of the active-set estimate that ensures a significant reduction in the objective function when setting to the bounds all those variables estimated active. In the second stage, a truncated-Newton strategy is used in the subspace of the variables estimated non-active. In order to properly combine the two phases, a proximity check is included in the scheme. This new tool, together with the other theoretical features of the two stages, enables us to prove global convergence. Furthermore, under additional standard assumptions, we can show that the algorithm converges at a superlinear rate. Promising experimental results demonstrate the effectiveness of the proposed method.

description: We provide a possible way of avoiding the hair-loss problem by studying gauge fluctuations on a classical Schwarzschild black hole background. The hair-loss problem arises due to the small fidelity of reconstructing the interior operator at the end stage of the evaporation, which is general in most schemes trying to decouple the early and late radiation to avoid firewall. To circumvent the problem, we put the black hole in a cavity as a toy model and study the entropy behavior of the system with different temperatures. By analyzing gauge fluctuations with nontrivial boundary conditions, we find that the entropy of the black hole system increases at the end stage, rather than directly dropping to zero. Besides the end stage, the entropy is the same as Page's original argument. The hair-loss problem can be avoided by the proposed model and we can gain important insights into the end stage of the evaporation and quantum effects of gravity.

Merging black hole binaries in galactic nuclei: implications for advanced-LIGO detections

description: Motivated by the recent detection of gravitational waves from the black hole binary merger GW150914, we study the dynamical evolution of black holes in galactic nuclei where massive star clusters reside. With masses of ~10^7M_Sun and sizes of only a few parsecs, nuclear star clusters are the densest stellar systems observed in the local universe and represent a robust environment where (stellar mass) black hole binaries can dynamically form, harden and merge. We show that due to their large escape speeds, nuclear star clusters can keep a large fraction of their merger remnants while also evolving rapidly enough that the holes can sink back to the central regions where they can swap in new binaries that can subsequently harden and merge. This process can repeat several times and produce black hole mergers of several tens of solar masses similar to GW150914 and up to a few hundreds of solar masses, without the need of invoking extremely low metallicity environments or implausible initial conditions. We use a semi-analytical approach to describe the formation and dynamics of black holes in massive star clusters. We find a black hole binary merger rate per volume from nuclear star clusters of ~1.5 Gpc^-3 yr^-1, implying up to a few tens of possible detections per year with Advanced LIGO. Our models suggest a local merger rate of 0.3- 1 Gpc^-3 yr^-1 for high mass black hole binaries similar to GW150914 (total mass >~ 50 M_Sun, redshift z< 0.3); a merger rate comparable to that of high mass black hole binaries that are dynamically assembled in globular clusters. Finally, we show that if all black holes receive high natal kicks, >~50km s^-1, then nuclear star clusters could dominate the local merger rate of binary black holes compared to the merger rate of similar binaries produced in either globular clusters or through isolated binary evolution.

description: The dynamical generation of a fermion gap in graphene is studied at the infra-red Lorentz-invariant fixed point where the system is described by an effective relativistic-like field theory: reduced QED$_{4,3}$ with $N$ four component fermions ($N=2$ for graphene), where photons are $(3+1)$-dimensional and mediate a fully retarded interaction among $(2+1)$-dimensional fermions. A correspondence between reduced QED$_{4,3}$ and QED$_3$ allows us to derive an exact gap equation for QED$_{4,3}$ up to next-to-leading order. Our results show that a dynamical gap is generated for $α> α_c$ where $1.03 < α_c < 1.08$ in the case $N=2$ or for $N < N_c$ where $N_c$ is such that $α_c \to \infty$ and takes the values $3.24 < N_c < 3.36$. The striking feature of these results is that they are in good agreement with values found in models with instantaneous Coulomb interaction. At the fixed point: $α= 1/137 \ll α_c$, and the system is therefore in the semi-metallic regime in accordance with experiments.

description: The notion of Mode 2 knowledge production (Gibbons et al. 1994, Nowotny et al. 2001) already has a remarkable history. It was launched fifteen years ago to capture the ongoing changes in the world of science, science policy and the knowledge economy at large. While it is not the only attempt to make sense of the change, it definitively is the most popular. Since its publication in 1994, ‘The New Production of Knowledge’ (Gibbons et al. 1994), which has coined the notions of Mode 1 and Mode 2, has received almost 1900 citations in scientific journals (see Figure 1). It is a blessing that it has helped both scholars and policymakers to get a grip on the profound changes going on in contemporary science systems. But the concept of Mode 2 knowledge production also proved to be a mixed blessing by creating confusion and by conflating interrelated yet independent trends.

Perception of High School Students towards Voluntary HIV Counseling and Testing, Using Health Belief Model in Butajira, SNNPR
Creators: name: Abebe, Abiy

description: A cross sectional descriptive study was conducted in January 2006, among Butajira senior secondary school students. The objective of the study was to assess the perception and attitude of the students towards voluntary counseling and testing (VCT) services based on Health Belief Model. A multi stage sampling method was used to fill 658 self-administered questionnaires of which 638 were returned complete making the respondent rate of 96.9%. Among the respondents, 415(65%) were males and 223(35%) were females. The mean age of the students was 16.25± 2.09. Of both sex mix, 129(20.22%) of the respondents had sexual experience i.e. 16.92% of the males and 3.3% of the females. The majority, 96.7% of them had heard about VCT services from different sources but only 118(18.5%) of the students had undergone VCT. Eighty two percent of the students were willing to undergo VCT. A theoretical construct with the intention to willingness to under go VCT was analyzed. Thus bi-variate regression analysis showed that willingness to VCT was significantly associated with perceived susceptibility AOR=0.37(0.28, 0.89), perceived barrier AOR= 0.45 (0.23, 0.89), perceived benefit AOR=1.79 (1.44, 2.49) Even if majority of the students had high level of knowledge, still they were engaged in risky sexual behavior. About half of the students had low perception ix towards acquiring HIV. Therefore, Information, education and communication programs should be established and emphasis should be put on reproductive health in order to encourage the students to avoid unsafe sex. HIV preventive messages like VCT should emphasis on personal susceptibility to HIV/ AIDS. Self-efficacy of the students to use VCT should be strengthened and quantitative study on perceived barriers and benefit of VCT should be conducted.

description: While the roundworm Caenorhabditis elegans is best known as a genetic model system, recent advances in biology have led some researchers to reconsider this small nematode in its natural context. In the last decade, hundreds of C. elegans strains have been isolated from the wild and whole-genome sequenced. These new population genetic resources have enabled the application of powerful complementary techniques to this well-characterized animal. Here, I apply genome-wide association to two complex polygenic traits in wild populations of C. elegans: magnetosensation & alcohol response.

description: This paper addresses the identification of Arabic handwritten digits. In addition to digit identifiability, the paper presents digit recognition. The digit image is divided into grids based on the distribution of the black pixels in the image. Several types of features are extracted (viz. gradient, curvature, density, horizontal and vertical run lengths, stroke, and concavity features) from the grid segments. K-Nearest Neighbor and Nearest Mean classifiers are used. A database of 70000 of Arabic handwritten digit samples written by 700 writers is used in the analysis and experimentations. The identifiability of isolated and combined digits are tested. The analysis of the results indicates that Arabic digits 3 (٣), 4 (٤), 8 (٨), and 9 (٩) are more identifiable than other digits while Arabic digit 0 (٠) and 1 (١) are the least identifiable. In addition, the paper shows that combining the writer’s digits increases the discriminability power of Arabic handwritten digits. Combining the features of all digits, K-NN provided the best accuracy in text-independent writer identification with top-1 result of 88.14%, top-5 result of 94.81%, and top-10 results of 96.48%.

description: Telomerase, a potential marker for tumorigenesis, has been found to be activated in more than 85-90% of human cancer. Curcumin is the major biologically active, yellow phytochemical compound of Curcuma longa (Zingiberaceae). The present study is aimed to investigate the capacity of curcumin on the regulation of telomerase activity and induction of apoptosis in P388D1 mouse lymphoma cells. Here, we demonstrate that curcumin at a concentration of 3.5 µM and an incubation period of 48h induces apoptosis and inhibits telomerase activity in the P388D1 cells. Curcumin induced apoptosis and telomerase activity in P388D1 lymphoma cells was confirmed by enumeration of apoptotic cells, % DNA fragmentation and RT-PCR. The culture supernatant of lymphoma cells treated with curcumin showed a higher level of nitric oxide content. RT-PCR analysis revealed over expression of TNF-α and IL-1β and inhi-bition of the antiapoptotic Bcl-2 and human catalytic subunit hTERT in the curcumin treated lymphoma cells as compared to untreated cells. Taken together the result shows that curcumin could significantly inhibit tumor proliferation and induce apoptosis in lymphoma cells. Thus, curcumin should be further tested as a possible antineoplastic agent.

description: We study modeling of two-phase flow in highly heterogeneous fractured and porous media. The flow behaviour is strongly influenced by mass transfer between a highly permeable (mobile) fracture domain and less permeable (immobile) matrix blocks. We quantify the effective two-phase flow behaviour using a multirate rate mass transfer (MRMT) approach. We discuss the range of applicability of the MRMT approach in terms of the pertinent viscous and capillary diffusion time scales. We scrutinize the linearization of capillary diffusion in the immobile regions, which allows for the formulation of MRMT in the form of a non-local single equation model. The global memory function, which encodes mass transfer between the mobile and the immobile regions, is at the center of this method. We propose two methods to estimate the global memory function for a fracture network with given fracture and matrix geometry. Both employ a scaling approach based on the known local memory function for a given immobile region. With the first method, the local memory function is calculated numerically, while the second one employs a parametric memory function in form of truncated power-law. The developed concepts are applied and tested for fracture networks of different complexity. We find that both physically based parameter estimation methods for the global memory function provide predictive MRMT approaches for the description of multiphase flow in highly heterogeneous porous media.
