The problem of adversarial attacks to a black-box model when no queries are allowed has posed great challenge the community and been extensively investigated. In this setting, one simple yet effective method is transfer obtained examples from attacking surrogate models fool target model. Previous works have studied what kind can generate more transferable examples, but their performances still ...

The men-having-sex-with-men (MSM) population has become one of the major risk groups for HIV-1 infection in the Asia Pacific countries. Hong Kong is located in the centre of Asia and the transmission history of HIV-1 subtype B transmission among MSM remained unclear. The aim of this study was to investigate the transmission dynamics of HIV-1 subtype B virus in the Hong Kong MSM population. Samp...

This paper studies method of simulated moments (MSM) estimators that are implemented using Bayesian methods, specifically Markov chain Monte Carlo (MCMC). Motivation and theory for the methods is provided by Chernozhukov Hong (2003). The shows, experimentally, confidence intervals these may have coverage which far from nominal level, a result has parallels in literature overidentified GMM estim...

Estimating usual food intake distributions from short-term quantitative measurements is critical when occasionally or rarely eaten food groups are considered. To overcome this challenge by statistical modeling, the Multiple Source Method (MSM) was developed in 2006. The MSM provides usual food intake distributions from individual short-term estimates by combining the probability and the amount ...

background: musculoskeletal manifestations (msm) of inflammatory bowel diseases (ibds) are usually the most frequent extraintestinal manifestations. however, they are not paid enough attention during regular office visits. this cross-sectional study aimed to draw a clinical picture of msm and their relationships with other findings in patients with ibd. materials and methods: patients of our ib...

BACKGROUND In the context of a generalized epidemic and criminalization of homosexuality, men who have sex with men (MSM) in Malawi have a disproportionate burden of HIV compared to other adults. Past research has documented low uptake of HIV prevention and health services among MSM, self-reported fear of seeking health services, and concerns of disclosure of sexual orientation and discriminati...

OBJECTIVES Men who have sex with men (MSM) bear the greatest burden of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in every state in the U.S., but their populations are poorly defined. We estimated and compared populations of MSM in 2007 by region, state, and race/ethnicity. METHODS We averaged findings from two statistical models we had previously developed t...

BACKGROUND Men who have sex with men (MSM) are at high risk of HIV infection. For developing proper interventions, it is important to know the size of MSM population. However, size estimation of MSM populations is still a significant public health challenge due to high cost, hard to reach and stigma associated with the population. OBJECTIVES We aimed to estimate the social network size (c val...

BACKGROUND The present permanent deferral policy in Israel for MSM was established in 1977 and was based on the previous (now outdated) USA Food and Drug Administration standards. This study analyses epidemiological data regarding blood donations among MSM, in order to estimate the risk for HIV transfusion transmitted infection (TTI) if the policy is changed to allow at-risk MSM to donate blood...

BACKGROUND Black/white disparities in HIV incidence and prevalence among men who have sex with men (MSM) in the United States remain largely unexplained. We examined the impact on HIV prevalence and incidence of interventions that decrease disparities in HIV care. Deciding which interventions have most impact on reducing disparities is critical. METHODS Using available US Centers for Disease ...
