description: We study the linear and non-linear bias parameters which determine the mapping between the distributions of galaxies and the full matter density fields, comparing different measurements and predictions. Associating galaxies with dark matter haloes in the MICE Grand Challenge N-body simulation we directly measure the bias parameters by comparing the smoothed density fluctuations of haloes and matter in the same region at different positions as a function of smoothing scale. Alternatively we measure the bias parameters by matching the probability distributions of halo and matter density fluctuations, which can be applied to observations. These direct bias measurements are compared to corresponding measurements from two-point and different third-order correlations, as well as predictions from the peak-background model, which we presented in previous articles using the same data. We find an overall variation of the linear bias measurements and predictions of $\sim 5 \%$ with respect to results from two-point correlations for different halo samples with masses between $\sim 10^{12} - 10^{15}$ $h^{-1}M_\odot$ at the redshifts $z=0.0$ and $0.5$. Variations between the second- and third-order bias parameters from the different methods show larger variations, but with consistent trends in mass and redshift. The various bias measurements reveal a tight relation between the linear and the quadratic bias parameters, which is consistent with results from the literature based on simulations with different cosmologies. Such a universal relation might improve constraints on cosmological models, derived from second-order clustering statistics at small scales or higher-order clustering statistics.

Year: 2013

description: Background: - Premarital sex results not only expose to STDs including HIV and AIDS, but also unwanted pregnancy for females. In addition, unwanted pregnancy among female students may lead to school dropout and a failure to complete their education. Therefore, studying about the magnitude and factors associated with premarital sex among in school youth in this area is an essential issue to overcome young people from sexual related problems and to support programmers and policy makers in providing information. Objectives: - The objective of this study is to assess the magnitude and factors associated with premarital sex. Methods: - a comparative cross sectional study that employed quantitative data collection method was used. The study was conducted on May 2013 in Bishoftu preparatory school among 530 students (265 male and 265 female students). Bivariate analysis was used to describe some of the socio-demographic variables, and logistic regression model was used to measure the association of outcome variables of different characteristics of the study subjects. Results were presented using tables and figures. Result: Out of 530 samples size 504 participated in the study. About 21.6% of the respondents were sexually active; the majorities were females within the age group of 20-24 years. More than half of the sexually active students (59.6%), had their first sexual intercourse in the age group of 15-18 years, mean (+SD) age of first sexual contact were found to be 18.24(+1.493) years respectively. Twenty one percent of the respondents had multiple sexual partners and among the sexually active students 57.8% never used condom at first sex. Age, living arrangement (living with friends ), go to Bars, narcotics intake, pornography film or magazine and peer pressure for doing sex were found to be significantly associated with premarital sex(AOR: 0.550, 95%CI: 0.316, 0.956), (AOR: 3.678, 95%CI: 1.180, 11.463), (AOR: 6.802, 95%CI: 3.540, 13.067), (AOR: 7.471, 95%CI: 1.849, 30.193), (AOR: 3.000, 95%CI: 1.700, 5.295), (AOR: 2.915, 95%CI: 1.687, 5.038), respectively. Conclusion and recommendation: -From this study, one can conclude that there is a high prevalence of premarital sexual practices among youths. Therefore, an integrated effort needs to be initiated to address such youths sexual and reproductive health problems through ICC/BCC services about sexual and reproductive health in general and premarital sex and its consequences in particular within the school environment

description: Icosahedral virus capsids are composed of symmetrons, organized arrangements of capsomers. There are three types of symmetrons: disymmetrons, trisymmetrons, and pentasymmetrons, which have different shapes and are centered on the icosahedral 2-fold, 3-fold and 5-fold axes of symmetry, respectively. In 2010 [Sinkovits & Baker] gave a classification of all possible ways of building an icosahedral structure solely from trisymmetrons and pentasymmetrons, which requires the triangulation number T to be odd. In the present paper we incorporate disymmetrons to obtain a geometric classification of icosahedral viruses formed by regular penta-, tri-, and disymmetrons. For every class of solutions, we further provide formulas for symmetron sizes and parity restrictions on h, k, and T numbers. We also present several methods in which invariants may be used to classify a given configuration.

A Game-theoretic Approach for Provably-Uniform Random Number Generation in Decentralized Networks
Creators: name: Cai, Zhuo
Publisher: name: arXiv
Year: 2023
Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: Many protocols in distributed computing rely on a source of randomness, usually called a random beacon, both for their applicability and security. This is especially true for proof-of-stake blockchain protocols in which the next miner or set of miners have to be chosen randomly and each party's likelihood to be selected is in proportion to their stake in the cryptocurrency. Current random beacons used in proof-of-stake protocols, such as Ouroboros and Algorand, have two fundamental limitations: Either (i)~they rely on pseudorandomness, e.g.~assuming that the output of a hash function is uniform, which is a widely-used but unproven assumption, or (ii)~they generate their randomness using a distributed protocol in which several participants are required to submit random numbers which are then used in the generation of a final random result. However, in this case, there is no guarantee that the numbers provided by the parties are uniformly random and there is no incentive for the parties to honestly generate uniform randomness. Most random beacons have both limitations. In this thesis, we provide a protocol for distributed generation of randomness. Our protocol does not rely on pseudorandomness at all. Similar to some of the previous approaches, it uses random inputs by different participants to generate a final random result. However, the crucial difference is that we provide a game-theoretic guarantee showing that it is in everyone's best interest to submit uniform random numbers. Hence, our approach is the first to incentivize honest behavior instead of just assuming it. Moreover, the approach is trustless and generates unbiased random numbers. It is also tamper-proof and no party can change the output or affect its distribution. Finally, it is designed with modularity in mind and can be easily plugged into existing distributed protocols such as proof-of-stake blockchains.

description: Coarse architectural models are often generated at scales ranging from individual buildings to scenes for downstream applications such as Digital Twin City, Metaverse, LODs, etc. Such piece-wise planar models can be abstracted as twins from 3D dense reconstructions. However, these models typically lack realistic texture relative to the real building or scene, making them unsuitable for vivid display or direct reference. In this paper, we present TwinTex, the first automatic texture mapping framework to generate a photo-realistic texture for a piece-wise planar proxy. Our method addresses most challenges occurring in such twin texture generation. Specifically, for each primitive plane, we first select a small set of photos with greedy heuristics considering photometric quality, perspective quality and facade texture completeness. Then, different levels of line features (LoLs) are extracted from the set of selected photos to generate guidance for later steps. With LoLs, we employ optimization algorithms to align texture with geometry from local to global. Finally, we fine-tune a diffusion model with a multi-mask initialization component and a new dataset to inpaint the missing region. Experimental results on many buildings, indoor scenes and man-made objects of varying complexity demonstrate the generalization ability of our algorithm. Our approach surpasses state-of-the-art texture mapping methods in terms of high-fidelity quality and reaches a human-expert production level with much less effort.

description: Background: Women traditionally have suffered socio-cultural and economic discrimination. Thus they are easily influenced by their partners' decisions even on issues related to prevention of mother-to-child transmission of HIV/AIDS. Inadequate male involvement in pregnancy and PMTCT of HIV programmes have been identified as major bottlenecks to effective programme implementation. Objective: This study was designed to assess the male partners influence and factors on pregnant women towards voluntary HIV testing and support on PMTCT in hospitals of Addis Ababa. Method and Materials: Cross-sectional survey was conducted using structured pre-tested questionnaire on 423 HIV pre-test counseled pregnant women at five public hospitals that provide PMTCT services in Addis Ababa. The study was complimented with four FGDs and it was launched from December 2006 to January 2007. Key findings: Male partners, who had presented to PMTCT centers along with women, were found to be 10.4%; and 47.3% of the pregnant women were reported to be influenced by their male partners on decision of HIV testing. Those women who had not influenced by their male partners on HIV testing 2.56 times likely to accept HIV testing than who had not. Multiple factors were looked in study whether an association exists with male partner influence on pregnant Assessment of male partners influence on pregnant women towards voluntary HIV testing and support on PMTCT in hospitals of Addis Ababa. By: Abenet Takele vii women towards HIV testing or not: being married [AOR (95%CI) = 3.35(1.66- 11.38)], living with the male partner [AOR (95%CI) = 3.23(1.09-8.41)], economical dependence [AOR (95% CI) = 3.09 (1.84-5.90)]. Pregnant women need their male partner psychological, social and financial support as well as active involvement in PMTCT services in order to utilize the service properly. Recommendations: Besides intensifying IEC program to encourage the male partners to utilize PMTCT, care and support the pregnant women, empowering of women to make informed choices about VCT and PMTCT in providing intensive information were suggested. Supporting women to become economically independent through income generating projects as well as the strengthening of male friendly counseling at PMTCT providing institutions were also recommended.

description: The recent detections of the binary black hole mergers GW150914 and GW151226 have inaugurated the field of gravitational-wave astronomy. For the two main formation channels that have been proposed for these sources, isolated binary evolution in galactic fields and dynamical formation in dense star clusters, the predicted masses and merger rates overlap significantly, complicating any astrophysical claims that rely on measured masses alone. Here, we examine the distribution of spin- orbit misalignments expected for binaries from the field and from dense star clusters. Under standard assumptions for black-hole natal kicks, we find that black-hole binaries similar to GW150914 could be formed with significant spin-orbit misalignment only through dynamical processes. In particular, these heavy-black-hole binaries can only form with a significant spin-orbit anti-alignment in the dynamical channel. Our results suggest that future detections of merging black hole binaries with measurable spins will allow us to identify the main formation channel for these systems.

Year: 2004

description: The Extended Parallel Process Model (EPPM) provides useful information to understand the health communication messages gap. The survey was conducted to assess perception level of the risk communication variables and to examine whether the risk communication variables are predictors to HIV/AIDS prevention practices. A cross-sectional study was conducted based on EPPM in December 2003 among Bahir Dar University students. Self-administrative questionnaire prepared in English was used to collect data. Data analysis and interpreted was done using appropriate statistical methods. In this study 456-second year and above students participated. The result showed that 166(34.6%) of the students, more males than females (P<0.001) had ever had sexual intercourse. Condom use among those who had sex in 12 months prior to the survey was about 52%. A belief of personal susceptibility was very low particularly for females (1.8±1.05), (P<0.001) perceived severity was moderately high (3.8±1.32) and the perception of efficacy was high for abstinence (4.5±0.97) and seems undecided for condom (2.9±1.09). Females strongly agreed (4.2± 1.15) (P<0.001) than males (3.7±1.28) that they could able to be abstinent. The study participants reported low selfefficacy regarding condom use. Male students moderately agreed (3.5 ±1.16; P<0.001) than females (2.6±1.25) for self-efficacy of condom use). They had extremely positive attitude towards abstinence (4.5 ± 0.83) good for monogamy (4.0 ± 1.06) and fair attitude (3.1±1.15) towards condom use. Correlation and regression analysis of risk communication and outcome variables showed that perceived response-efficacy, selfefficacy towards condom and perception of susceptibility were predictors for condom use and self-efficacy was predictor for being abstinent. Credible source of information were cited as persons living with HIV/AIDS, religious persons and health personnel. Most important type of messages were with real experience and preferred way of learning was reported as religious affiliated, peer education and discussion with families. This study revealed that among health communication variables self-efficacy is strong predictor and response-efficacy, and perceived susceptibility are moderate predictors particularly for condom use. Where as perception of severity of disease was not related with response behaviors. Therefore, models/theory needs to be used to assess, design, develop and promote health intervention messages. Key words perception of threat, susceptibility, severity, efficacy, response- efficacy, self-efficacy, no response, danger control fear control

Using the eROSITA data obtained in the period from December 2019 to February 2022, we have found 1325 sources the X-ray flux from which in the 0.3-2.3 keV energy band changed by more than a factor of 10 at a confidence level of at least 99.73 %. Of them, 635 objects have been classified as AGNs or AGN candidates. We describe the procedure of searching for highly variable sources and the selection of extragalactic objects among them and describe the statistical properties of the produced catalog. We provide a catalog of 49 sources for which a statistically significant flux in their low state was detected. For the latter we provide their light curves and X-ray spectra and discuss in detail the most interesting of them.

description: The chemical modification of graphene with adatoms is of importance for nanoelectronics applications. Based on first-principles density-functional theory calculations with including van der Waals interactions, we present a comparative study of the diffusion characteristics of oxygen (O) and fluorine (F) atoms both on graphene and between the layers of bilayer graphene. We find that O and F atoms have lower binding energies between the layers of bilayer graphene compared to on graphene. Interestingly, the calculated diffusion barrier for the O atom slightly increases from 0.81 eV on graphene to 0.85 eV within bilayer graphene, while that for the F atom significantly decreases from 0.30 eV on graphene to 0.18 eV within bilayer graphene. Such contrasting behaviors of the O and F diffusions within bilayer graphene can be traced to their different bonding natures: i.e., the O adatom that has a strongly covalent C$-$O$-$C bonding on the bridge site of the C$-$C bond diffuses on one graphene layer with a slight interference of the other layer, while the F adatom that has a weakly ionic F$-$C bonding on top of a C atom easily diffuses by hopping between two graphene layers with accepting more electron charges from the two layers. The present findings have important implications for understanding the diffusion processes of F and O atoms on graphene and within bilayer graphene.

description: Automatic License Plate Recognition (ALPR) has been the focus of many researches in the past years. In general, ALPR is divided into the following problems: detection of on-track vehicles, license plates detection, segmention of license plate characters and optical character recognition (OCR). Even though commercial solutions are available for controlled acquisition conditions, e.g., the entrance of a parking lot, ALPR is still an open problem when dealing with data acquired from uncontrolled environments, such as roads and highways when relying only on imaging sensors. Due to the multiple orientations and scales of the license plates captured by the camera, a very challenging task of the ALPR is the License Plate Character Segmentation (LPCS) step, which effectiveness is required to be (near) optimal to achieve a high recognition rate by the OCR. To tackle the LPCS problem, this work proposes a novel benchmark composed of a dataset designed to focus specifically on the character segmentation step of the ALPR within an evaluation protocol. Furthermore, we propose the Jaccard-Centroid coefficient, a new evaluation measure more suitable than the Jaccard coefficient regarding the location of the bounding box within the ground-truth annotation. The dataset is composed of 2,000 Brazilian license plates consisting of 14,000 alphanumeric symbols and their corresponding bounding box annotations. We also present a new straightforward approach to perform LPCS efficiently. Finally, we provide an experimental evaluation for the dataset based on four LPCS approaches and demonstrate the importance of character segmentation for achieving an accurate OCR.

description: Background: Emergency contraception refers to type of contraception that is used as an emergency procedure to prevent unintended pregnancy following an unprotected act of sexual intercourse. Every year, unintended pregnancies lead to at least 20 million unsafe abortions, resulting in the death of some 80,000 women. There is low utilization of emergency contraception, while awareness is relatively high. Objective: To assess level of awareness, attitude and utilization of emergency contraception and factors influencing knowledge, attitude and practice. Methods: A cross-sectional survey was conducted on February 2007. There were a total of 2167 female students in 10 colleges in Asella town. Eight hundred thirty three of them were sampled for the study. Self administered questionnaire and in-depth interview was used to collect data. Result: The magnitude of sexual violence was as high as 47.9% and unwanted pregnancy was 16.9% for those who practiced sex. From 833 respondents 228 (27.4%) have knowledge about emergency contraception; Correct timing of emergency contraception was reported only by 82 (9.8%) and 20 (2.4%) of them had ever used emergency contraception. Oral contraceptive pill was the most widely used 13 (65.0%). Health professionals were main source of information 126 (55.3%), but some of the health workers have no in-service training on emergency contraception. About 548 (65.8%) of the respondents had favorable attitude towards the use of emergency contraception. All of the health institutions were not providing family planning or emergency contraception services for college students, beside the clinics in the college had no family planning program. Conclusion: There is high sexual violence & sexual harassment (high rate of unintended sex); low awareness, knowledge and utilization of emergency contraceptives among college female students and no favorable access to the service. Hence there is a need for collaborated effort to improve service quality and prevent female students/women from life threatening behaviors

description: This is a community based cross-sectional study conducted in Hossana Town southern Ethiopia n from December to January 2004; to assess the role of currently married men age 20-64 years in contraceptive use and fertility presences. A multistage sampling procedure was carried out to interview 776 men in study area. A pre-tested structured questionnaire complemented with focus group discussion was the main instrument used for data collection. The study revealed that median age at marriage was found to be 25.9 years in the Study are. Average number of living children in the study area was found to be 3.84, while ideal number of children desired was 5.2 children per men. Ninety one point five percent of the study population has heard of contraception and 79.4% of the study population knew at least one method of contraception. The contraceptive prevalence in Hossana Town was 47.6%. Among the non-users of family planning 13% of respondents mentioned desired to have more children, 8.4% mentioned that respondent opposed, followed by fear of side effects (5.4%), religious prohibition (4.5%) and known no methods was (2.7%). Fourteen point six percent of men in the study area was discontinued using family planning due to desire to have more children. The most commonly mentioned reason for using contraception among current users was childspacing by 30.7% and the second most commonly mentioned reason was child limiting by 17.5%. Thirty –seven point eight percent of men in the study area have never used family planning methods. Fifty-nine point four percent of men in the study area have mentioned intention to use family planning in the near future. Knowledge about contraception, family size, discussion with wives about family planning and fertility in the family, attitudes of respondents and their partners were found to be determinates for contraception. Participating of men in family planning service delivery system, maximizing access to good quality services, improving the quality of family planning services, and making contraceptive method mix easier to obtain and use will help to meet need of many men

description: Background: Morbidity and mortality related to HIV/AIDS remain unacceptably high in developing countries, despite major advance in HIV therapy and increased international funding on HIV/AIDS. Individual's ability to obtain, consume and utilize food is compromised by HIV/AIDS. It causes morbidity and mortality as a result of poor nutritional status and weight loss. Interactions between antiretroviral therapy (ART) and nutrition can affect medication efficacy, nutritional status, and adherence to drug regimens. The concept of enhancing access to food among PLWHA and managing the interactions between ART and food and nutrition is critical remains critical. Objective: To assess food security, nutritional status and their association with adherence of HAART among adult People living with HIV/AIDS. Methods: A hospital based cross-sectional survey was conducted between December 2010 and February 2011 among adult (≥18 years) PLWHA on HAART with a complementary qualitative interview among HAART adherence supporters at selected public hospitals of Addis Ababa, Ethiopia. A total of 394 adult PLWHA systematically selected and participated in the study having a 100% response rate. Semi structured and structured questionnaires, adopted from FANTA were used to collect data on food security. BMI measurements were taken to assess nutritional status. Univariate, bivariate and multivariate logistic regression analysis was done using SPSS version 16. Qualitative content analysis was done after importing the transcribed text onto the Open code program. Result: Majority 252 (65%) of the study participants were females, 305 (77%) in the age group 25-44 years. Overall 293(74.4%) PLWHA were food insecure with 95% CI: (70.09, 78.71). And the rate of self reported adherence based on the combined indicator of the dose and time adherence measurement was 321(81.5%) with 95% CI: (77.67, 85.33). Only 61(16.5%) with 95% CI: (12.83, 20.17) were underweight. Household's monthly income (≤500 ETB) predicted food insecurity (AOR, 6.37; 95% CI, 2.98-13.63). And there was no statistical significant association between food security and self reported HAART adherence. II food security, nutritional status & their association with HAART adherence Conclusions & recommendations: Large number of adult PLWHA was food insecure. Wide ranges of coping strategies were taken to cope with food insecurity. Self reported HAART adherence was high. Medium to long term intervention aiming at generating and diversifying income to improve self reliance of PLWHA would help mitigate the food insecurity problem.

description: The state-of-the-art neural video codecs have outperformed the most sophisticated traditional codecs in terms of RD performance in certain cases. However, utilizing them for practical applications is still challenging for two major reasons. 1) Cross-platform computational errors resulting from floating point operations can lead to inaccurate decoding of the bitstream. 2) The high computational complexity of the encoding and decoding process poses a challenge in achieving real-time performance. In this paper, we propose a real-time cross-platform neural video codec, which is capable of efficiently decoding of 720P video bitstream from other encoding platforms on a consumer-grade GPU. First, to solve the problem of inconsistency of codec caused by the uncertainty of floating point calculations across platforms, we design a calibration transmitting system to guarantee the consistent quantization of entropy parameters between the encoding and decoding stages. The parameters that may have transboundary quantization between encoding and decoding are identified in the encoding stage, and their coordinates will be delivered by auxiliary transmitted bitstream. By doing so, these inconsistent parameters can be processed properly in the decoding stage. Furthermore, to reduce the bitrate of the auxiliary bitstream, we rectify the distribution of entropy parameters using a piecewise Gaussian constraint. Second, to match the computational limitations on the decoding side for real-time video codec, we design a lightweight model. A series of efficiency techniques enable our model to achieve 25 FPS decoding speed on NVIDIA RTX 2080 GPU. Experimental results demonstrate that our model can achieve real-time decoding of 720P videos while encoding on another platform. Furthermore, the real-time model brings up to a maximum of 24.2\% BD-rate improvement from the perspective of PSNR with the anchor H.265.

description: Background: Breast cancer is the most frequently diagnosed reproductive organ cancers (ROCs) among women in Ethiopia. Even though breast self-examination (BSE) is shown to be the least expensive, less time consuming and noninvasive screening method, various studies conducted in Ethiopia showed that the practice of breast self-examination is poor. Women"s perception to breast cancer and BSE, which is considered as an important influencing factor in determining the likelihood of performing BSE, have not received enough attention particularly among female teachers. Therefore this study examined the predictors of BSE among female secondary school teachers based on the health belief model (HBM). Method: Institution based cross sectional study was conducted among female secondary school teachers in Addis Ababa, from March to April 2018. Structured self-administered questionnaire based on the revised champions health belief model instrument (RCHBM) was used for data collection. Sample size was 589 and teachers were selected randomly from thirty four public secondary schools after proportionally allocating to each school. Data was analyzed using SPSS version 21 for descriptive and logistic regression analysis was used to identify factors associated with BSE performance with corresponding 95% confidence interval. Result: a total of 566 female teachers participated in this study with 96.1% response rate. Majority of respondents 430(76%) have ever heard about BSE. More than half of the participants 56.4% reported that they never performed BSE. After controlling possible confounding variables in the multivariable logistic regression, personal history of breast problem, teaching experience, knowledge and perceived self-efficacy were significantly associated with performing BSE. Conclusion and recommendation: The practice of breast self-examination was discovered to be relatively low. Perceived self-efficacy, personal history of breast problem, teaching experience and knowledge were significant predictors of BSE performance. This emphasizes the need for designing and implementing well-designed school based education programs to improve their awareness that underline the necessity of early screening and enhancing their self-efficacy through demonstration of correct procedures on performing breast self-examination.

description: Galaxy clusters undergo mergers that can generate extended radio sources called radio relics. Radio relics are the consequence of merger-induced shocks that propagate in the intra cluster medium (ICM). In this paper we analyse the radio, optical and X-ray data from a candidate galaxy cluster that has been selected from the radio emission coming from a candidate radio relic detected in NRAO VLA Sky Survey (NVSS). Our aim is to clarify the nature of this source and prove that under certain conditions radio emission from radio relics can be used to trace relatively low-mass galaxy clusters. We have observed the candidate galaxy cluster with the Giant Meterwave Radio Telescope (GMRT) at three different frequencies. These datasets have been analysed together with archival data from ROSAT in the X-ray and with archival data from the Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) telescope in four different optical bands. We confirm the presence of a 1 Mpc long radio relic located in the outskirts of a previously unknown galaxy cluster. We confirm the presence of the galaxy cluster through dedicated optical observations and using archival X-ray data. Due to its proximity and similar redshift to a known Abell cluster, we named it: Abell 3527-bis. The galaxy cluster is among the least massive cluster known to host a radio relic. We showed that radio relics can be effectively used to trace a subset of relatively low-mass galaxy clusters that might have gone undetected in X-ray or Sunyaev-Zel'dovich (SZ) surveys. This technique might be used in future deep, low-frequency surveys as those carried on by LOFAR, uGMRT and, ultimately, SKA.
