Virologic failure and second-line antiretroviral therapy in children in South Africa--the IeDEA Southern Africa collaboration [PDF]
, 2011 Article approval pendingWith expanding pediatric antiretroviral therapy (ART) access, children will begin to experience treatment failure and require second-line therapy. We evaluated the probability and determinants of virologic failure and switching in

Some advances in importance sampling of reliability models based on zero variance approximation [PDF]
, 2012 We are interested in estimating, through simulation, the probability of entering a rare failure state before a regeneration state. Since this probability is typically small, we apply importance sampling.

Minimal failure probability for ceramic design via shape control [PDF]
, 2014 We consider the probability of failure for components made of brittle mate- rials under one time application of a load as introduced by Weibull and Batdorf - Crosse and more recently studied by NASA and the STAU cooperation as an objective functional in ...

Weibull Failure Probability Estimation Based on Zero-Failure Data [PDF]
Mathematical Problems in Engineering, 2015 Reliability testing is often carried out with small sample sizes and short duration because of increasing costs and the restriction of development time. Therefore, for highly reliable products, zero-failure data are often collected in such tests, which could not be used to evaluate reliability by traditional methods.

Polar Codes with exponentially small error at finite block length [PDF]
, 2018 We show that the entire class of polar codes (up to a natural necessary condition) converge to capacity at block lengths polynomial in the gap to capacity, while simultaneously achieving failure probabilities that are exponentially small in the block ...

Distinguishing two-qubit states using local measurements and restricted classical communication [PDF]
, 2002 The problem of unambiguous state discrimination consists of determining which of a set of known quantum states a particular system is in. One is allowed to fail, but not to make a mistake.

Journal of Civil Engineering and Management, 2004 Safety, reliability and risk are key issues in the preservation of our built, cultural heritage. Several structural collapses make us aware of the vulnerability of our technical and natural environment and demand an adequate engineering response.

Earth's Future, 2022 Compound flooding, caused by the simultaneous or successive occurrence of two or more flood mechanisms, is mainly associated with extreme precipitation, river overflows, and storm tides across coastal areas. The interdependencies between these components
