description: Very-high-energy gamma rays produce electron positron pairs in interactions with low-energy photons of extragalactic background light during propagation through the intergalactic medium. The electron-positron pairs generate secondary gamma rays detectable by gamma-ray telescopes. This secondary emission can be used to detect intergalactic magnetic fields (IGMF) in the voids of large-scale structure. A new gamma-ray observatory, namely, Cherenkov Telescope Array (CTA), will provide an increase in sensitivity for detections of these secondary gamma-ray emission and enable the measurement of its properties for sources at cosmological distances. The interpretation of the CTA data, including detection of IGMF and study of its properties and origins, will require precision modeling of the primary and secondary gamma-ray fluxes. We asses the precision of the modeling of the secondary gamma-ray emission using model calculations with publicly available Monte-Carlo codes CRPropa and ELMAG and compare their predictions with theoretical expectations and with model calculations of a newly developed CRbeam code. We find that model predictions of different codes differ by up to 50% for low-redshift sources, with discrepancies increasing up to order-of-magnitude level with the increasing source redshifts. We identify the origin of these discrepancies and demonstrate that after eliminating the inaccuracies found, the discrepancies between the three codes are reduced to 10% when modeling nearby sources with z~0.1. We argue that the new CRbeam code provides reliable predictions for spectral, timing and imaging properties of the secondary gamma-ray signal for both nearby and distant sources with z~1. Thus, it can be used to study gamma-ray sources and IGMF with a level of precision that is appropriate for the prospective CTA study of the effects of gamma-ray propagation through the intergalactic medium.

description: We describe the gluon parton distribution function (PDF) in the proton, deduced by data from the ATLAS and HERA experiments, in the framework of the parton statistical model. The best fit parameters involved in the Planck formula that describes the gluon distribution are consistent with the results obtained from analysis of deep inelastic scattering processes. Remarkably, the agreement between the statistical model and the experimental gluon distributions is found with the same value of the "temperature" parameter $\bar{x}$ found by fitting the valence parton distributions from deep inelastic scattering. This result corroborates the validity of the statistical approach in the gluon sector.

The representation involves quantum dilogarithm type infinite products in the $n(n-1)/2$-fold tensor product of $q$-bosons. It leads to a matrix product formula of the stationary probabilities in the $U_q(A_n^{(1)})$-zero range process on a one-dimensional periodic lattice.

description: Liver elastography is a recent non-invasive diagnostic technique that is used to investigate the degree of liver fibrosis. Furthermore, metabolic syndrome and its parameters such as obesity, resistance to insulin, HDL decrease and hypertriglyceridaemia affect the degree of fibrosis. An equally important role in the above correlation plays the co morbidity of diabetes mellitus.The aim of the current thesis is the correlation of liver elastography with metabolic indexes in obese patients with or without diabetes mellitus. Α sample of 28 obese patients with type II diabetes mellitus and 29 obese patients without type II diabetes was assembled. For the statistical analysis the data from indexes regarding the metabolic syndrome was used as well as the results of the elastography examination.According to the data from the statistical analysis, liver fibrosis is affected by different metabolic indexes in obese patients with and without type II diabetes mellitus. Furthermore, the elastography results show a greater degree of fibrosis in the first category of patients, a fact that can be contributed mainly in the insulin resistance that is evident.

description: In the spacetime induced by a rotating cosmic string we compute the energy levels of a massive spinless particle coupled covariantly to a homogeneous magnetic field parallel to the string. Afterwards, we consider the addition of a scalar potential with a Coulomb-type and a linear confining term and completely solve the Klein-Gordon equations for each configuration. Finally, assuming rigid-wall boundary conditions, we find the Landau levels when the linear defect is itself magnetized. Remarkably, our analysis reveals that the Landau quantization occurs even in the absence of gauge fields provided the string is endowed with spin.

Assessment of Pregnancy Risk perception and contraceptive use among female college students in Shashamane town
Creators: name: Tesa, Edao
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: BACKGROUND: The adolescent period is a time at which individuals explore and develop their sexuality, gender and sex role. These factors have a profound influence on a young person's current and future health. It is believed that age at menarche is declining, and that premarital adolescent sexual activity is increasing. Clearly, if this change in behavior is not compensated by an increase in premarital use of contraception, it is expected that there will be an increase in the proportion of out-of-wedlock adolescent births, as well as an increase in the prevalence of induced abortion which ends in high proportion of maternal mortality rate. OBJECTIVE: The objective of this study is to assess pregnancy risk perception and contraceptive use among college student in Shashamane town. METHODS: A cross- sectional descriptive survey was carried out among college students in Shashamane Woreda, Western Arsi Zone, from February 15th to may 2011. A total of six hundred seventeen subjects were involved with response rate of 100%. To collect data, a pre- tested self administered questionnaire was used. RESULTS: Out of the total students 314(50.9%) were sexually active. The mean age for first sexual initiation was 17yrs with 1.4yrs of SD. The likelihood of becoming sexually active was lower among students from other Woreda than from Shashamane and two times higher among students who live with friends in rented house at significant level of association (AOR=0.5519;95%CI;0.3648,0.8349) and(AOR=2.44;95%CI;1.5581,3.8334) respectively. Out of the total respondent only 287(46.5%) knew the exact days of ovulation .Among the sexually active respondents, 164(52.2%) had ever used IX contraceptive . The odds of contraceptive use among students who have low perception about the weight of being pregnant is extremely low ( AOR=0.31;95%CI;0.19, 0.5) CONCLUSION: From this study, it was concluded that the age of the sexual debut among college youths were too early. Contraceptive utilization and self-risk perception toward unwanted pregnancy among youths were also very low. Youths also lack comprehensive knowledge about phase of ovulation. The likely hood of contraceptive use among students with low perception is low. RECOMMENDATION: IEC programs should be put on reproductive health in order to encourage the youths to delay sex and negotiate contraceptive use. Young people rely heavily up on interpersonal contacts for sexual information, peer based intervention should be implemented to ascertain that youths have access to accurate information.

description: We study geodesics flows on curved quantum Riemannian geometries using a recent formulation in terms of bimodule connections and completely positive maps. We complete this formalism with a canonical $*$ operation on noncommutative vector fields. We show on a classical manifold how the Ricci tensor arises naturally in our approach as a term in the convective derivative of the divergence of the geodesic velocity field, and use this to propose a similar object in the noncommutative case. Examples include quantum geodesic flows on the algebra of 2 x 2 matrices, fuzzy spheres and the $q$-sphere.

description: We extend our prescription for the construction of a covariant and background-independent effective action for scalar quantum field theories to the case where momentum modes below a certain scale are suppressed by the presence of an infrared regulator. The key step is an appropriate choice of the infrared cutoff for which the Ward identity, capturing the information from single-field dependence of the ultraviolet action, continues to be exactly solvable, and therefore, in addition to covariance, manifest background independence of the effective action is guaranteed at any scale. A practical consequence is that in this framework one can adopt truncations dependent on the single total field. Furthermore we discuss the necessary and sufficient conditions for the preservation of symmetries along the renormalization group flow.

description: We use the type theory for rings of operators due to Kaplansky to describe the structure of modules that are invariant under automorphisms of their injective envelopes. Also, we highlight the importance of Boolean rings in the study of such modules. As a consequence of this approach, we are able to further the study initiated by Dickson and Fuller regarding when a module invariant under automorphisms of its injective envelope is invariant under any endomorphism of it. In particular, we find conditions for several classes of noetherian rings which ensure that modules invariant under automorphisms of their injective envelopes are quasi-injective. In the case of a commutative noetherian ring, we show that any automorphism-invariant module is quasi-injective. We also provide multiple examples that show that our conditions are the best possible, in the sense that if we relax them further then there exist automorphism-invariant modules which are not quasi-injective. We finish this paper by dualizing our results to the automorphism-coinvariant case.

description: Background: According to the Center for Disease Control and prevention, surgical site infections are classified as being incisional and organ space that must develop within 30 days of operation. Objective: The objective of this research was to assess the effectiveness of taking 1day against 7 days antibiotic prophylaxis on maternal infection after cesarean section Methodology: A prospective follow up study was conducted in which 209 women were grouped into exposed and non-exposed arms based on PO antibiotics given on discharge date. Each patient was observed in the post-operative ward and was followed back to home till 30 days from the operation day. Four hourly temperatures was taken as long as they stay in the hospital. Fever developing or persisting for 48 hours of >37oc after surgery was included as the febrile morbidity. Wound was examined on 3rd, 7th, 14th, 21st.and 30 rd. Comparisons between groups was obtained by x2 test. Stratified analyses, survival analysis and Cox regression was used to identify risk factors for infection. Results were reported with 95% confidence interval (CI). Result: in the 7 day antibiotics group 51 mothers (50%) had ruptured membranes compared with 40 (37.4%) in the 1 day antibiotics group but it was not significant at 5% level of significance (p = 0.06). The mean duration of operation room stay was 34.50 ± 6.265 minutes in the exposed group and 35.14 ± 5.89 minutes in an unexposed group (p = 0.30). During the study period, a total of 30 mothers (14.3%) infected giving an infection incidence rate of 5.1 per 1000 person-days, 179 (85.6%) were censored well, while total of 8 (3.8%) were lost to follow up. For 7 days prophylactic groups, 14 infection (13.2%) were reported, giving an overall infection rate of 4 per 1000 person-days, while in a 1 day prophylactic antibiotics group 16 (15.5%) infection were reported giving a incidence rate of 5 per 1000 person-days(P<0.8). In conclusion, our study showed that there was no significant difference between the two groups in terms of single day doses versus multiple day's doses of antibiotic prophylaxis against postoperative infection in emergency caesarean section. So I recommend physicians to prescribe 1 day regimen prophylactic antibiotics. 1 |

description: Quantum spin liquid is a nontrivial magnetic state of longstanding interest, in which spins are strongly correlated and entangled but do not order1, 2; further intriguing is its doped version, which possibly hosts strange metal and unconventional superconductivity3. Promising and currently the only candidate of the doped spin liquid is a triangular-lattice organic conductor, kappa-(BEDT-TTF)4Hg2.89Br8, recently found to hold metallicity, spin-liquid-like magnetism and BEC-like superconductivity4-6. The nature of the metallic state with the spin-liquid behaviour is awaiting to be further clarified. Here, we report the thermoelectric signature that mobile holes in the spin liquid background is in a quantum critical state and it pertains to the BEC-like superconductivity. The Seebeck coefficient divided by temperature, S/T, is enhanced on cooling with logarithmic divergence indicative of quantum criticality. Furthermore, the logarithmic enhancement is correlated with the superconducting transition temperature under pressure variation, and the temperature and magnetic field profile of S/T upon the superconducting transition change with pressure in a consistent way with the previously suggested BEC-BCS crossover. The present results reveal that the quantum criticality in a doped spin liquid emerges in a phase, not at a point, and is involved in the unconventional BEC-like nature.

description: We study the power spectra of f(R) inflation using a new technique in which the norm-squared of the mode functions is evolved. Our technique results in excellent analytic approximations for how the spectra depend upon the function $f(R)$. Although the spectra are numerically the same in the Jordan and Einstein frames for the same wave number $k$, they depend upon the geometries of these frames in quite different ways. For example, the power spectra in the two frames are different functions of the number of e-foldings until end of inflation. We discuss how future data on reheating can be used to distinguish f(R) inflation from scalar-driven inflation.

For this aim we estimated the angles ? between the rotation axis and the magnetic moment of the neutron star for 376 radio pulsars using three different methods. It was shown that there was the predominance of small inclinations of the magnetic axes. Using the obtained values of the angle ? we calculated the equatorial magnetic inductions for pulsars considered. These inductions are several times higher as a rule than corresponding values in the known catalogs.

description: We introduce families of rational functions that are biorthogonal with respect to the $q$-hypergeometric distribution. A triplet of $q$-difference operators $X$, $Y$, $Z$ is shown to play a role analogous to the pair of bispectral operators of orthogonal polynomials. The recurrence relation and difference equation take the form of generalized eigenvalue problems involving the three operators. The algebra generated by $X$, $Y$, $Z$ is akin to the algebras of Askey--Wilson type in the case of orthogonal polynomials. The actions of these operators in three different basis are presented. Connections with Wilson's ${}_{10}ϕ_9$ biorthogonal rational functions are also discussed.

description: Background: Shared modes of transmission of infection with HIV and hepatitis B and/or C virus, have made them important causes of morbidity and mortality in HIV infected persons receiving antiretroviral drugs. The magnitude of HBV and HCV co and triple infection among HIV patients has not been known in Jimma zone. Objective: To determine the prevalence of hepatitis B and C; and associated risk factors among HIV positive individuals in Jimma zone, Ethiopia, 2016. Methods: A facility based cross sectional study based on secondary data were conducted on an anonymous samples collected for VCT at Jimma specialized hospital from January, 2015 to May, 2016. A questionnaire adapted for this study was used to collect data on demographic characteristics, associated risk factors, and serological status of HBV/HCV among HIV positive individuals. Results: A history of four hundred eleven HIV positive individuals were included in the study, Majority of participants were female65.5%. Age (28.8±11.2) year were enrolled. Thirty three (8.0%)[95% CI, 5.2–10.3] were HBV positive, twenty (4.9%) [95% CI, 2.8–6.9] were HCV positive and four (1.0%) [95% CI, 0.2–2.3] were HBV/HCV/HIV triple infected. Rural residency shown to be independent predictor for HCV [AOR = 2.81; 95% CI 1.03–7.68]. Conclusions: These findings suggest that co-infection and triple co-infection is similar with the general population in the study setting. Therefore, it is important to implement a screening program for HIV positive individuals for active infection of HBV and HCV is therefore necessary.

description: The human thymus is the site of T-cell maturation andninduction of central tolerance. Hematopoietic stem cell (HSC)-derived progenitors are recruited to the thymus from the fetal liver during early prenatal development and from bone marrow at later stages and postnatal life. The mechanism by which HSCs are recruited to the thymus is poorly understood in humans, though mouse models have indicated the critical role of thymic stromal cells (TSC). Here, we developed a 3D microfluidic assay based on human cells to model HSC extravasation across the endothelium into the extracellular matrix. We found that the presence of human TSC consisting of cultured thymic epithelial cells (TEC) and interstitial cells (TIC) increases the HSC extravasation rates by 3-fold. Strikingly, incorporating TEC or TIC alone is insufficient to perturb HSC extravasation rates. Furthermore, we identified complex gene expressions from interactions between endothelial cells, TEC and TIC modulates the HSCs extravasation. Our results suggest that comprehensive signaling from the complex thymic microenvironment is crucial for thymus seeding and that our system will allow manipulation of these signals with the potential to increase thymocyte migration in a therapeutic setting.

In this article we make an experimental comparison between the uniformity of NbTiN thin films produced by two DC magnetron sputtering systems with vastly different target sizes: the Nordiko 2000 equipped with a circular 100mm diameter target, and the Evatec LLS801 with a rectangular target of 127 mm x 444.5 mm. In addition to the films deposited staticly in both systems, we have also deposited films in the LLS801 while shuttling the substrate in front of the target, with the aim of further enhancing the uniformity. Among these three setups, the LLS801 system with substrate shuttling has yielded the highest uniformity in film thickness (+/-2%), effective resistivity (decreasing by 5% from center to edge), and superconducting critical temperature (T_c = 15.0 K - 15.3 K) over a 100 mm diameter wafer. However, the shuttling appears to increase the resistivity by almost a factor of 2 compared to static deposition. Surface SEM inspections suggest that the shuttling could have induced a different mode of microstructural film growth.

description: Much work has been carried out to investigate the genetic and epigenetic basis of endometriosis and proposed that endometriosis has been described as an epigenetic disease. The purpose of this study was to extract the imprinting genes that are associated with endometriosis development. Methods: The information on the imprinting genes can be accessed publicly from a web-based interface at http://www.geneimprint.com/site/genes-by-species. Results: In the current version, the database contains 150 human imprinted genes derived from the literature. We searched gene functions and their roles in particular biological processes or events, such as development and pathogenesis of endometriosis. From the genomic imprinting database, we picked 10 genes that were highly associated with female reproduction; prominent among them were paternally expressed genes (DIRAS3, BMP8B, CYP1B1, ZFAT, IGF2, MIMT1, or MIR296) and maternally expressed genes (DVL1, FGFRL1, or CDKN1C). These imprinted genes may be associated with reproductive biology such as endometriosis, pregnancy loss, decidualization process and preeclampsia. Discussion: This study supports the possibility that aberrant epigenetic dysregulation of specific imprinting genes may contribute to endometriosis predisposition.

description: Hydrodynamical simulations of star formation often do not possess the dynamic range needed to fully resolve the build-up of individual stars and star clusters, and thus have to resort to subgrid models. A popular way to do this is by introducing Lagrangian sink particles, which replace contracting high density regions at the point where the resolution limit is reached. A common problem then is how to assign fundamental stellar properties to sink particles, such as the distribution of stellar masses. We present a new and simple statistical method to assign stellar contents to sink particles. Once the stellar content is specified, it can be used to determine a sink particle's radiative output, supernovae rate or other feedback parameters that may be required in the calculations. Advantages of our method are (i) it is simple to implement, (ii) it guarantees that the obtained stellar populations are good samples of the initial mass function, (iii) it can easily deal with infalling mass accreted at later times, and (iv) it does not put restrictions on the sink particles' masses in order to be used. The method works very well for sink particles that represent large star clusters and for which the stellar mass function is well sampled, but can also handle the transition to sink particles that represent a small number of stars.

description: Variational quantum algorithms are a promising class of algorithms that can be performed on currently available quantum computers. In most settings, the free parameters of a variational circuit are optimized using a classical optimizer that updates parameters in Euclidean geometry. Since quantum circuits are elements of the special unitary group, we can consider an alternative optimization perspective that depends on the structure of this group. In this work, we investigate a Riemannian optimization scheme over the special unitary group and we discuss its implementation on a quantum computer. We illustrate that the resulting Riemannian gradient-flow algorithm has favorable optimization properties for deep circuits and that an approximate version of this algorithm can be performed on near-term hardware.

description: We investigate the real-time evolution of lattice bosons in two spatial dimensions whose dynamics is governed by a Markovian quantum master equation. We employ the Wigner-Weyl phase space quantization and derive the functional integral for open quantum many-body systems that governs the time evolution of the Wigner function. Using the truncated Wigner approximation, in which quantum fluctuations are only taken into account in the initial state whereas the dynamics is governed by classical evolution equations, we study the buildup of long-range correlations due to the action of non-Hermitean quantum jump operators that constitute a mechanism for dissipative cooling. Starting from an initially disordered state corresponding to a vortex condensate, the dissipative process results in the annihilation of vortex-antivortex pairs and the establishment of quasi long-range order at late times. We observe that a finite vortex density survives the cooling process which disagrees with the analytically constructed vortex-free Bose-Einstein condensate at asymptotic times. This indicates that quantum fluctuations beyond the truncated Wigner approximation need to be included to fully capture the physics of dissipative Bose-Einstein condensation.

description: We investigate the influence of slab thickness on the electronic structure of the Si(100)-p(2x2) surface in density functional theory (DFT) calculations, considering both density of states and band structure. Our calculations, with slab thicknesses of up to 78 atomic layers, reveal that the slab thickness profoundly affects the surface band structure, particularly the dangling bond states of the silicon dimers near the Fermi level. We find that, to precisely reproduce the surface bands, the slab thickness needs to be large enough to completely converge the bulk bands in the slab. In case of the Si(100) surface, the dispersion features of the surface bands, such as the band shape and width, converge when the slab thickness is larger than 30 layers. Complete convergence of both the surface and bulk bands in the slab is only achieved when the slab thickness is greater than 60 layers.

description: This thesis analyzes the regulatory framework of the duration of pre-trial or temporary detention and its control process and discusses issues related to Articles 292 and 293 of the Criminal Procedure Code from a theoretical and practical perspective. The following systematic approach is followed: First, the evolution of constitutional and procedural regulations relating to the duration of pre-trial detention is briefly presented. Then, in framing the concept of the duration of pre-trial detention, the start and end of pre-trial detention is defined and the related issue of the coincidence of time served and provisional detention is addressed. Regarding the control of the duration of pre-trial detention, emphasis is placed on the points of the time of control, the competence, the justification of the relevant judgment, the procedural actions of the competent bodies and the right of the accused to be heard. Subsequently, issues concerning the procedural framework of doubts and objections regarding the extension or supplementation of the maximum limits of pre-trial detention are analyzed, as well as issues concerning the imposition of restrictive conditions. Finally, the difficulties that arise when imposing pre-trial detention in the context of multiple offences are highlighted.

description: We initiate the study of parameterized complexity of $\textsf{QMA}$ problems in terms of the number of non-Clifford gates in the problem description. We show that for the problem of parameterized quantum circuit satisfiability, there exists a classical algorithm solving the problem with a runtime scaling exponentially in the number of non-Clifford gates but only polynomially with the system size. This result follows from our main result, that for any Clifford + $t$ $T$-gate quantum circuit satisfiability problem, the search space of optimal witnesses can be reduced to a stabilizer subspace isomorphic to at most $t$ qubits (independent of the system size). Furthermore, we derive new lower bounds on the $T$-count of circuit satisfiability instances and the $T$-count of the $W$-state assuming the classical exponential time hypothesis ($\textsf{ETH}$). Lastly, we explore the parameterized complexity of the quantum non-identity check problem.
Determinants of Onchocerciasis Infection and Its Impact on Health and Productivity in Teppi Coffee Plantation Field Workers

description: A cross-sectional survey of onchocerciasis in male field workers was conducted in Teppi Coffee Plantation Project, Baya Farm, in November-December 1991. The objectives were to assess the magnitude of the problem, to measure the sensitivity of various diagnostic procedures, to assess the effect on onchocerciasis infection of various exposure factors, and to determine the effect of the disease on work productivity. A total of 196 study subjects participated in the study. They were interviewed to assess their exposure status and complaints of rheumatism. Physical examination was conducted and measurements on weight and height, and on visual acuity were taken. Parasitological diagnosis was based on skin biopsies from the calf, hip, and scapula bilaterally. Labor cards were reviewed over the previous twelve months to assess various indicators of work productivity. A case-control analysis was performed. It was found that the prevalence rate of onchocerciasis was very high (82.8%), as compared to other studies conducted in Ethiopia. This was ascribed to the selection of the study population, whose age, gender, and exposure status made it prone to contract the disease. No study subject had any detectable visual impairment and other chronic manifestations were few. This was attributed partially to the "healthy worker effect". Parasitological diagnosis detected 93.8% of the cases while clinical diagnosis only detected 35.8% of the cases. v In this study it was not possible to establish the protective effect of being always fully clothed at work and having less riverassociated activities. This was attributed to the cumulative effect of exposure to many different sources due to the long sojourn of study subjects in endemic areas . Workers with onchocerciasis were significantly more likely to be absent from work due to illness and other reasons, and earned significantly less wages than workers without onchocerciasis, thus demonstrating that non-blinding onchocerciasis has a negative impact on work productivity
