Year: 2005

description: Qualitative study was conducted in Addis Ababa to investigate factors predisposing street children to HIV/AIDS among children aged 5-18 years,to explore individual behavioral factors that increase sexual risk behaviors and to assess the socio economic and societal influence on the street children sexual behavior .The participant were selected using homogenous sampling and informants who are familiar with the target population ,culture and have rich information were selected .The study has triangulated focus group discussion ,key informant interview and non participatory observation using open ended thematize question guide, interview guide and checklists respectively. Data analysis was done manually in the field and using computer soft ware for handling qualitative data .HIV/AIDS was a relatively low concern to the street children due to their preoccupation with survival and adverse environment, levels of HIV/AIDS knowledge was relatively high, though most not put it in practice because of mood change due to substance use and alcohol intake. Majority consider themselves to be victims of the deadly disease HIV/AIDS, moreover stigmatized by the community and government organs .They believe condom use reduces sexual pleasure and perceive sex to be more natural. The driving force that put them to use substance and alcohol were the usual and regular onset of depression ,stress ,boredom and to relive hunger ,cope with harsh realities of life ,to avert fear ,sad and to get confidence .Peer to be sexually active ,families tendency to monitor their children were found to be associated with risky sexual practices ,children tendency to chew chat ,smoke cigarette ganja ,shisha and drink alcohol were reported as the factor putting street children at risk of unsafe sexual practices and HIV infection, girls in the street are at higher risk of rape and its consequences, ,HIV/AIDS and STIs. Homosexuality was also evident among some street boys. Promoting media education, focusing on child rearing practice and peer education to get children out of substance abuse and unsafe sex by creating street based activities and mini project scheme. Appropriate and consistent IEC/BCC target oriented need to be disseminated , to this specific social group, more over banning all substance offering houses, chewing in the street, and its circulation. Changing the outlook and mistreatment of children by community and government organs to wards the street children

description: Recent observations of the microwave sky, by the space telescopes such as WMAP and Planck, have opened a new window into the analysis of continuum emission from supernova remnants (SNRs). In this paper, different emission models that can explain the characteristic shape of presently known integrated radio/microwave continuum spectrum of the Galactic SNR IC 443 are tested and discussed. In particular, the possibility that the slight bump in the integrated continuum of this remnant around 20 -- 70~GHz is genuine and that can be explained by the contribution of additional emission mechanism such as of spinning dust is emphasized. We find that adding a spinning dust component to the emission model improves the fit of the integrated spectrum of this SNR while, at the same time preserves the physically probable parameter values. Finally, models that include the high-frequency synchrotron bending of the IC 443 radio to microwave continuum are favored.

description: Recently we calculated the contribution of Leutwyler zero mode chromons to the Yang-Mills effective Lagrangian by integrating over collective coordinates of the nonlinearly interacting zero modes. Here we analyse the behaviour of the partition function prefactor and the integration measure Jacobian of the zero modes and show that these factors do not contribute to the effective Lagrangian.

description: We revisit the scenario of primordial black hole (PBH) formation from large curvature perturbations generated during the waterfall phase transition in hybrid inflation models. In a minimal setup considered in the literature, the mass and abundance of PBHs are correlated and astrophysical size PBHs tend to be overproduced. This is because a longer length scale for curvature perturbations (or a larger PBH mass) requires a longer waterfall regime with a flatter potential, which results in overproduction of curvature perturbations. However, in this paper, we discuss that the higher-dimensional terms for the inflaton potential affect the dynamics during the waterfall phase transition and show that astrophysical size PHBs of order $10^{17\text{--}23} \, {\rm g}$ (which can explain the whole dark matter) can form in some parameter space consistently with any existing constraints. The scenario can be tested by observing the induced gravitational waves from scalar perturbations by future gravitational wave experiments, such as LISA.

description: Rayleigh-Bénard convection (RBC) is a recurrent phenomenon in several industrial and geoscience flows and a well-studied system from a fundamental fluid-mechanics viewpoint. However, controlling RBC, for example by modulating the spatial distribution of the bottom-plate heating in the canonical RBC configuration, remains a challenging topic for classical control-theory methods. In the present work, we apply deep reinforcement learning (DRL) for controlling RBC. We show that effective RBC control can be obtained by leveraging invariant multi-agent reinforcement learning (MARL), which takes advantage of the locality and translational invariance inherent to RBC flows inside wide channels. The MARL framework applied to RBC allows for an increase in the number of control segments without encountering the curse of dimensionality that would result from a naive increase in the DRL action-size dimension. This is made possible by the MARL ability for re-using the knowledge generated in different parts of the RBC domain. We show in a case study that MARL DRL is able to discover an advanced control strategy that destabilizes the spontaneous RBC double-cell pattern, changes the topology of RBC by coalescing adjacent convection cells, and actively controls the resulting coalesced cell to bring it to a new stable configuration. This modified flow configuration results in reduced convective heat transfer, which is beneficial in several industrial processes. Therefore, our work both shows the potential of MARL DRL for controlling large RBC systems, as well as demonstrates the possibility for DRL to discover strategies that move the RBC configuration between different topological configurations, yielding desirable heat-transfer characteristics. These results are useful for both gaining further understanding of the intrinsic properties of RBC, as well as for developing industrial applications.

description: Background: Academic physicians, such as those affiliated with National Cancer Institute (NCI)–designated Comprehensive Cancer Centers, may have different practice patterns regarding the use of high-cost cancer drugs than nonacademic physicians. Materials and Methods: For this cohort study, we linked cancer registry, administrative, and demographic data for patients with newly diagnosed cancer in North Carolina from 2004 to 2011. We selected cancer types with multiple U.S. Food and Drug Administration–approved, National Comprehensive Cancer Network–recommended treatment options and large differences in reimbursement between higher-priced and lower-priced options (stage IV colorectal, stage IV lung, and stage II–IV head-and-neck cancers). We assessed whether provider's practice setting—NCI-designated Comprehensive Cancer Center (“NCI”) versus other location (“non-NCI”)—was associated with use of higher-cost treatment options. We used inverse probability of exposure weighting to control for patient characteristics. Results: Of 800 eligible patients, 79.6% were treated in non-NCI settings. Patients treated in non-NCI settings were more likely to receive high-cost treatment than patients treated in NCI settings (36.0% vs. 23.2%), with an unadjusted prevalence difference of 12.7% (95% confidence interval [CI], 5.1%–20.0%). After controlling for potential confounding factors, non-NCI patients remained more likely to receive high-cost treatment, although the strength of association was attenuated (adjusted prevalence difference, 9.6%; 95% CI −0.1%–18.7%). Exploratory analyses suggested potential heterogeneity across cancer type and insurance status. Conclusion: Use of higher-cost cancer treatments may be more common in non-NCI than NCI settings. This may reflect differential implementation of clinical evidence, local practice variation, or possibly a response to the reimbursement incentives presented by chemotherapy billing. Implications for Practice: Oncology care delivery and practice patterns may vary between care settings. By comparing otherwise similar patients treated in National Cancer Institute (NCI)–designated Comprehensive Cancer Centers with those treated elsewhere, this study suggests that patients may be more likely to receive treatment with certain expensive cancer drugs if treated in the non-NCI setting. These practice differences may result in differences in patient costs and outcomes as a result of where they receive treatment.
Merger of a White Dwarf-Neutron Star Binary to $10^{29}$ Carat Diamonds: Origin of the Pulsar Planets

description: We show that the merger and tidal disruption of a C/O white dwarf (WD) by a neutron star (NS) binary companion provides a natural formation scenario for the PSR B1257+12 planetary system. Starting with initial conditions for the debris disk produced of the disrupted WD, we model its long term viscous evolution, including for the first time the effects of mass and angular momentum loss during the early radiatively inefficient accretion flow (RIAF) phase and accounting for the unusual C/O composition on the disk opacity. For plausible values of the disk viscosity $α\sim 10^{-3}-10^{-2}$ and the RIAF mass loss efficiency, we find that the disk mass remaining near the planet formation radius at the time of solid condensation is sufficient to explain the pulsar planets. Rapid rocky planet formation via gravitational instability of the solid carbon-dominated disk is facilitated by the suppression of vertical shear instabilities due to the high solid-to-gas ratio. Additional evidence supporting a WD-NS merger scenario includes (1) the low observed occurrence rate of pulsar planets ($\lesssim 1\%$ of NS birth), comparable to the expected WD-NS merger rate; (2) accretion by the NS during the RIAF phase is sufficient to spin PSR B1257+12 up to its observed 6 ms period; (3) similar models of `low angular momentum' disks, such as those produced from supernova fallback, find insufficient mass reaching the planet formation radius. The unusually high space velocity of PSR B1257+12 of $\gtrsim 326\,{\rm km\,s}^{-1}$ suggests a possible connection to the Calcium-rich transients, dim supernovae which occur in the outskirts of their host galaxies and were proposed to result from mergers of WD-NS binaries receiving SN kicks. The C/O disk composition implied by our model likely results in carbon-rich planets with diamond interiors.

description: Two electrons in a quantum dot (QD) can form triplet states. We analyze the exchange coupling of the triplet states of the negatively charged exciton in a QD (X$^-$, two electrons and one hole) with the spin of a magnetic atom (Mn). Two techniques are used to access the spin structure of this magnetic complex: the resonant excitation of the excited states of X$^-$-Mn and the analysis of the emission of a negatively charged biexciton in a magnetic dot (XX$^-$-Mn). The photo-luminescence (PL) excitation of X$^-$-Mn reveals excited states with a circularly polarized fine structure which strongly depends on the Mn spin state S$_z$ and gives rise to negative circular polarization emission. This fine structure arises from the coupling of the triplet states of an excited charged exciton with the Mn (X$^{-*}$-Mn) and its S$_z$ dependence can be described by a spin effective model. The recombination of XX$^-$-Mn leaves in the dot a charged exciton in its excited state and the PL structure is controlled by the coupling of triplet states of X$^{-*}$ with the Mn spin. An analysis of the polarization and magneto-optic properties of this emission gives access to the electron-hole exchange interaction within the triplets states. Comparing the fine structure of the singlet X$^-$-Mn and of the triplets of X$^{-*}$-Mn we can independently study the different source of anisotropy in the QD: the valence band mixing and the exchange interaction in an anisotropic potential

description: The present dissertation attempts to analyse Turkey’s influence on the Western Balkan countries, through its application of “soft power”. First, there is an explanation of the term “soft power”, its characteristics and the position it holds in geopolitical strategies. It is followed by an analysis of Turkey’s “soft power” and its application toward the Western Balkan region in political, economic, and social terms. The states included are Serbia, Bosnia-Herzegovina, Montenegro, Republic of Kosovo, Albania and North Macedonia. The dissertation presents only briefly the first years that followed the dissolution of the Soviet Union and Yugoslavia and has an emphasis on the Justice and Development Party period (Α.Κ.Ρ. – Adalet ve Kalkınma Partisi). Turkish “soft power” is examined in the light of both official state initiatives, as well as those of the private sector. Within this context there will be a final attempt to assess the effectiveness of Turkish “soft power” through examining and comparing financial and trade statistics, alongside social indicators, related to Turkey and the countries-subjects of this dissertation

description: The aim of the present thesis was the study of the full span of implicit complements in Standard Modern Greek and the examination of the correct use of the diagnostic of direct object omission of Rappaport-Hovav and Levin (1998). We presented the existing literature and added new classes of implicit complements to it, creating the full typology in the first section. In the second section, we discussed a set of problematic predictions that the above-mentioned diagnostic makes. We tested the sorts of implicit complements that can exist in a sentence rendering the use of the diagnostic incorrect. We concluded that out of the four sorts of implicit complements that exist in Standard Modern Greek, only one kind guarantees the correct and safe use of the diagnostic. Then, we presented and analyzed three verb classes that threaten the manner-result complementarity hypothesis (Rappaport-Hovav and Levin, 1998) and we secured that this happens even with the sort of implicit complement with which the diagnostic is fully operative. The contribution of the present thesis is then two-fold, since it provides a full typology of a barely studied constituent and crosses its sets with a distinct hypothesis to corroborate the diagnostic of direct object omission

description: We analyze chiral topological edge modes in a non-Hermitian variant of the 2D Dirac equation. Such modes appear at interfaces between media with different "masses" and/or signs of the "non-Hermitian charge". The existence of these edge modes is intimately related to exceptional points of the bulk Hamiltonians, i.e., degeneracies in the bulk spectra of the media. We find that the topological edge modes can be divided into three families ("Hermitian-like", "non-Hermitian", and "mixed"), these are characterized by two winding numbers, describing two distinct kinds of half-integer charges carried by the exceptional points. We show that all the above types of topological edge modes can be realized in honeycomb lattices of ring resonators with asymmetric or gain/loss couplings.

description: The vanishing affine connections have been used solely while adopting the modified $f(Q)$ gravity theory to the cosmology. Consequently, researchers could not get beyond what is already known in $f(T)$ theory earlier. To alleviate this problem, in the present manuscript we investigate a recently proposed construction of $f(Q)$ theory using non-vanishing affine connection in the spatially flat FLRW spacetime. We then investigate the cosmological solutions of $f(Q)$ theory for a perfect fluid through the phase space analysis. We introduce few variables and dimensionless parameters to construct the corresponding equations suitable for the dynamical system approach. The conservation of the energy-momentum tensor leads to a constraint equation that relates the dynamical variables. Briefly, both unstable and stable de Sitter solutions appear which correspond to early and late times accelerated expansions. Also, unstable points corresponding to the matter dominated and radiation dominated eras have been found which do exist for every $f(Q)$ function. As a result, the present discussion shows that $f(Q)$ gravity endowed by non-vanishing affine connections is capable of explaining a true sequence of cosmic eras.

description: Σκοπός της διατριβής ήταν η μελέτη του Αγίου Όρους στις τελευταίες δεκαετίες του 19ου αιώνα, έως και την απελευθέρωσή του το 1912. Μελετήθηκε το ιστορικό πλαίσιο και όλα τα γεγονότα προ, κατά τη διάρκεια και μετά την απελευθέρωση της περιοχής. Ταυτόχρονα μελετήθηκαν ζητήματα όπως αυτό της ανακήρυξης της αυτονομίας του Αγίου Όρους στο πλαίσιο του Ελληνικού Κράτους, το Ιερό Ψήφισμα του 1913 καθώς και το ζήτημα του Πανσλαβισμού στο Άγιον Όρος. Στη συνέχεια παρουσιάσαμε αναλυτικά τα χαρακτηριστικά της εξέλιξης των μοναστηριακών συγκροτημάτων μέσω της αρχιτεκτονικής σκοπιάς του αντικειμένου της εποχής, αναφερόμενοι αναλυτικά σε αυτά. Τέλος, ασχοληθήκαμε επιπλέον με την καλλιτεχνική παραγωγή της εξεταζόμενης περιόδου και τα πεδία εφαρμογής της (φορητές εικόνες, τοιχογραφίες και υπόλοιπες μορφές καλλιτεχνικής παραγωγής γλυπτική, ξυλογλυπτική, μικροτεχνία), ενώ έγινε και η περιγραφή-μελέτη κάποιων χαρακτηριστικών έργων. Παράλληλα, εκδόθηκαν χρήσιμα συμπεράσματα για το αντικείμενο ενδιαφέροντος και την ιστορική, εθνική και πολιτιστική του προέκταση
description: The purpose of the thesis was the study of Mount Athos in the last decades of the 19th century, until its liberation in 1912. The historical context and all the events before, during and after the liberation of the area were studied. At the same time, issues such as the proclamation of the autonomy of Mount Athos within the context of the Greek State, the Holy Resolution of 1913 as well as the issue of Pan-Slavism on Mount Athos were studied. Then we presented in detail the characteristics of the development of the monastic complexes through the architectural point of view of the object of the time, referring to them in detail. Finally, we also dealt with the artistic production of the examined period and its fields of application (portable images, murals and other forms of artistic production, sculpture, woodcarving, micro-art), while the description-study of some characteristic works was also done. At the same time, useful conclusions were issued about the subject of interest and its historical, national and cultural extension

description: The Quantum Chromodynamics (QCD) coupling, $α_s$, is not a physical observable of the theory since it depends on conventions related to the renormalization procedure. We introduce a definition of the QCD coupling, denoted by $\hatα_s$, whose running is explicitly renormalization scheme invariant. The scheme dependence of the new coupling $\hatα_s$ is parameterized by a single parameter $C$, related to transformations of the QCD scale $Λ$. It is demonstrated that appropriate choices of $C$ can lead to substantial improvements in the perturbative prediction of physical observables. As phenomenological applications, we study $e^+e^-$ scattering and decays of the $τ$ lepton into hadrons, both being governed by the QCD Adler function.

description: Back ground: Along with the increased survival of children infected with HIV, disclosure of HIV status to children remains a complex and a critical clinical issue in the care of HIV-infected children. Disclosed HIV status has been identified as one of the factors associated with better adherence and also essential for the secondary prevention of HIV transmission. However, HIV status disclosure of adolescent represents a challenge for the family and for medical staff. Objective: To assess the magnitude of HIV serostatus disclosure and its effect on ART treatment adherence among HIV-infected adolescents in ART care and treatment providing health facilities in Addis Ababa. Methods: A facility based cross-sectional study design was conducted among 403 adolescents receiving ART in the selected six health facilities of Addis Ababa. Caregivers of adolescents of aged 10-18 years, were interviewed using a structured questionnaire. Three days intensive training was given for all supervisors and data collectors. Stepwise logistic regression was conducted to identify the association of disclosure to HIV status and with adherence to ARV medication, Data entry and analyses was carried out using EPI info and SPSS version 16 statistical packages respectively. X RESULT: Three hundred and ninety six parents of adolescents on ART participated in this study making the response rate at 98%. Median age of the adolescents was 14 years. The level of HIV states discloser was 47%. Data showed that age greater than 14 years [AOR=(95% CI) 5.20 = (2.46-12.29)] and lower educational states of the care givers[AOR=(95% CI) 5.20 = (2.46-12.29)] were significant predictors for being disclosed. Similarly being disclosed to their HIV status and being in a fixed dose HAART regimen [AOR=(95% CI)9.94,(4.48-22.08)] and [AOR and (95% CI) 8.40= (2.48-28.47)] respectively were significantly associated with good HAART adherence. CONCLUTION: More than half (53%) of the adolescents who participated in the study did not know their HIV serostatus however, disclosed HIV status was significantly associated with good HAART adherence. The disclosure process should be thus systematically encouraged and organized among adolescent populations in order to improve their ARV medication adherence and prevent further HIV transmission.

description: We discuss the emergence of a new symmetry generator in a Hamiltonian realisation of four-dimensional gauge theories in the flat space foliated by retarded (advanced) time. It generates an asymptotic symmetry that acts on the asymptotic fields in a way different from the usual large gauge transformations. The improved canonical generators, corresponding to gauge and asymptotic symmetries, form a classical Kac-Moody charge algebra with a non-trivial central extension. In particular, we describe the case of electromagnetism, where the charge algebra is the $\mathrm{U}(1)$ current algebra with a level proportional to the coupling constant of the theory, $κ=4π^2/e^2$. We construct bilinear generators yielding Virasoro algebras on the null boundary. We also provide a non-Abelian generalization of the previous symmetries by analysing the evolution of Yang-Mills theory in Bondi coordinates.

description: Bottlenose dolphins (Tursiops truncatus) live in complex individualized societies that combine stable social units with fluid groups, and they largely rely on sound to interact with one another. This thesis applies a suite of approaches to study their acoustic communication. I studied the wild population of Sarasota, which offers long-term behavioural data and opportunities to deploy sound-and-movement recording tags. Bottlenose dolphins display a wide call repertoire, including graded sounds challenging to classify. I use dolphin social interactions to present a novel tag-based approach for studying communicative roles of call parameters changes. Applying continuously-sampled parameters, this approach examines how individuals change movements as a function of signal features. I focus then on signature whistles, sounds encoding identity information that in Sarasota are documented for most individuals. Signature whistles function as individually-distinctive contact calls, for instance between closely-bonded animals during separation, but their function between groups is poorly documented. Analysing Dtag data from instances of group encounters, I show that dolphins did not regularly produce signature whistles upon detecting another group, nor systematically before joining; instead, signatures appeared to be used strategically depending on the encountered individuals. Dolphins sometimes imitate the signature whistle of others, which is thought to function for addressing known individuals. Performing first-ever playbacks of natural signature whistle copies, I show that free-ranging subjects turned more frequently towards the playback upon hearing copies of their signature vs signature whistles of others, supporting the addressing function of copies. Signature whistle copies are often produced right after the subject’s signature, in so-called vocal matching interactions. Using playbacks with temporarily-captured subjects, I test whether signature whistle matching, or vocal matching per se, has an addressing signalling role. Subjects turned more times and produced their signature more frequently in response to signature whistle matching vs matching of other calls, supporting the former hypothesis.

Magnitude and Associated Risk Factors of Diabetic Ketoacidosis in Newlydiagnosed Diabettis Melittus Children in Addis Ababa, Ethiopia
Creators: name: Atkilt, Helen
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: Background: Diabetic Ketoacidosis (DKA) is one of the most serious acute complications of Diabetes Mellitus (DM) and the leading cause of morbidity and 9 mortality in children with type 1 diabetes. The mortality rate for DKA ranges from 2 to 5 % in developed countries and 6 to 24% in developing countries. Objectives: To assess the magnitude and associated factors of DKA in newly diagnosed Diabetic Mellitus children in Addis Ababa. Method: A facility based cross sectional study was conducted in selected hospitals in Addis Ababa. Data was double entered from the paper-based abstraction sheet into Epi info version 7 and exported to SPSS version 21 for analysis. A descriptive analysis was performed. Bivariate and multivariate logistic analysis was used to identify factors associated with the magnitude of newly diagnosed Diabetic Ketoacidosis. Categorical variables were compared if necessary using odds ratio with levels of significance set at 5%. Result: The magnitude of DKA in newly diagnosed children found to be 35.8%. The significant predictors of DKA among newly diagnosed children were age of the child, parents' knowledge of the sign and symptoms of DKA 0.51(0.273, 0.95) sign and symptoms of DKA before the onset of DKA 0.348(0.206, 0.59) and infection prior to DKA onset 3.45(1.97, 6.04). Conclusion: The overall magnitude of DKA in children with newly diagnosed type 1 diabetes in Addis Ababa is low. In particular, children between 9-12 years of age and children whose parents don't know the sign and symptoms of DKA have a high risk of DKA at primary diagnosis of DM. The Diabetic Association should give different workshop for health professional and work on awareness creation for the society using different communication media.
Evanescent Wave Spectroscopy of Sublevel Resonances near a Glass/Vapor Interface

Year: 2002
Subjects: subject: 530

description: We report the observation of atomic sublevel coherence from a quasi-twodimensional region of atomic Na vapor near a glass surface. The ground state coherences are excited with a circularly polarized laser beam and detected with a linearly polarized probe beam that is incident on the interface under conditions of total interval reflection. The coherences of the atoms that are within the evanescent wave lead to selective absorption and phase shifts of the reflected beam which can be measured by a polarization-selective detection.

description: What do societies, the Internet, and the human brain have in common? They are all examples of complex relational systems, whose emerging behaviours are largely determined by the non-trivial networks of interactions among their constituents, namely individuals, computers, or neurons, rather than the properties of the units themselves. In the last two decades, network scientists have proposed models of increasing complexity to better understand real-world systems. Only recently we have realised that multiplexity, i.e. the coexistence of several types of interactions among the constituents of a complex system, is responsible for substantial qualitative and quantitative differences in the type and variety of behaviours that a complex system can exhibit. As a consequence, multilayer and multiplex networks have become a hot topic in complexity science. Here we provide an overview of some of the measures proposed so far to characterise the structure of multiplex networks, and a selection of models aiming at reproducing those structural properties and quantifying their statistical significance. Focusing on a subset of relevant topics, this brief review is a quite comprehensive introduction to the most basic tools for the analysis of multiplex networks observed in the real-world. The wide applicability of multiplex networks as a framework to model complex systems in different fields, from biology to social sciences, and the colloquial tone of the paper will make it an interesting read for researchers working on both theoretical and experimental analysis of networked systems.
