Abstract Mini-EUSO is part of the JEM-EUSO program and operates on board International Space Station (ISS). It a UV-telescope with single-photon counting capability looking at nighttime downwards to Earth through nadir-facing UV-transparent window. As pre-flight tests, engineering model, telescope 1/9 original focal surface lens 2.5 cm diameter, has been built tested. Tests model have made in l...

OBJECTIVE To study the relations between maternal occupational exposure to solvents during pregnancy and the risk of congenital malformations. METHODS A prospective population-based cohort, specifically designed to study the impact of maternal exposure to solvents on the risk of congenital malformations, began in 2002 in three districts of Brittany (France). 3421 pregnant women were recruited...

OBJECTIVES We tested the validity of a job exposure matrix (JEM) for coal tar pitch volatiles (CTPV) at a Söderberg aluminum smelter. The JEM had been developed by a committee of company hygienists and union representatives for an earlier study of cancer incidence and mortality. Our aim was to test the validity and reliability of the expert-based assignments. METHODS Personal CTPV exposure me...

OBJECTIVE To assess the contribution of workplace exposures to chronic obstructive pulmonary disease (COPD) risk in a community with a heavy burden of past industrial employment. METHODS A random population sample of Sheffield, U.K. residents aged over 55 years (n=4000), enriched with a hospital-based supplemental sample (n=209), was approached for study. A comprehensive self-completed questi...

OBJECTIVE To investigate the influence of maternal working conditions on fertility and pregnancy outcomes. METHODS 8880 women were enrolled in a large prospective birth cohort during early (76%), mid (21%) or late pregnancy (3%) (61% participation). Complete questionnaire information was available for 6302 women (71% response). Outcomes were prolonged time to pregnancy (TTP) (> 6 months), pre...

CONTEXT Retrospective exposure assessment in population-based case-control studies poses a major challenge due to the wide range of occupations and industries involved. The FINJEM is a generic job-exposure matrix (JEM) developed in Finland, which represents a potentially cost-effective exposure assessment tool. While FINJEM has been used in several studies outside Finland, little is known of it...

OBJECTIVE To develop a job-exposure matrix (JEM) that estimates exposure to eight variables representing different aspects of shiftwork among female workers. METHODS Occupational history and shiftwork exposure data were obtained from a population-based breast cancer case-control study. Exposure to light at night, phase shift, sleep disturbances, poor diet, lack of physical activity, lack of v...

Abstract Research showed that deep learning models are vulnerable to membership inference attacks, which aim determine if an example is in the training set of model. We propose a new framework defend against this sort attack. Our key insight we retrain original classifier with dataset independent while their elements sampled from same distribution, retrained will leak no information cannot be i...
