Background & objectives:AirQ software proved to be a valid and reliable tool to estimate the potential short term effects of air pollution. In this study the AirQ2.2.3 model was used to evaluate adverse health effects caused by nitrogen dioxide(NO2) exposure in Ahvaz during 2009. Materials & Methods:The AirQ,developed by the World Health Organization (WHO) to predi...
Prentice [1] offered a statistical definition of a surrogate endpoint as ‘a response variable for which a test of the null hypothesis of no relationship to the treatment groups under comparison is also a valid test of the corresponding null hypothesis based on the true endpoint’. A National Institutes of Health (NIH) working group generated less quantitatively rigorous definitions that contrast...
We demo an online system that tracks the availability of over four-hundred public SPARQL endpoints and makes up-to-date results available to the public. Our demo currently focuses on how often an endpoint is online/offline, but we plan to extend the system to collect metrics about available meta-data descriptions, SPARQL features supported, and performance for generic queries.
The 6-Minute Walk Distance (6-MWD) has been the most utilized endpoint for judging the efficacy of pulmonary arterial hypertension (PAH) therapy in clinical trials conducted over the past two decades. Despite its simplicity, widespread use in recent trials and overall prognostic value, the 6-MWD has often been criticized over the past several years and pleas from several PAH experts have emerge...
the study was carried out to develop an efficient approach for prediction the genotoxicity of carbon nanotubes. the experimental data on the bacterial reverse mutation test (ta100) on multi-walled carbon nanotubes (mwcnts) was collected from the literature and examined as an endpoint. by means of the optimal descriptors calculated with the monte carlo method a mathematical model of the endpoint...
BACKGROUND The efficacy of disease management programs in improving the outcome of heart failure patients remains uncertain and may vary across health systems. This study explores whether a countrywide disease management program is superior to usual care in reducing adverse health outcomes and improving well-being among community-dwelling adult patients with moderate-to-severe chronic heart fai...
We investigate helicity amplitudes (HAs) of A→BC-type decays for arbitrary spin towards the kinematic endpoint. show that HAs are proportional to product Clebsch-Gordan coefficients (CGC) and velocity a non-negative power. The latter can be zero in which case HA is non-vanishing at At endpoint explicit breaking rotational symmetry, through external momenta, restored findings interpreted as spec...
