We develop methods for estimating the size of hard-to-reach populations from data collected using network-based questions on standard surveys. Such data arise by asking respondents how many people they know in a specific group (e.g. people named Michael, intravenous drug users). The Network Scale up Method (NSUM) is a tool for producing population size estimates using these indirect measures of...

drought is random and nonlinear phenomenon and using linear stochastic models, nonlinear artificial neural network and hybrid models is advantaged for drought forecasting. this paper presents the performances of autoregressive integrated moving average (arima), direct multi-step neural network (dmsnn), recursive multi-step neural network (rmsnn), hybrid stochastic neural network of directive ap...

Abstract Objectives Osteitis and tissue remodeling are inflammatory processes associated with the severity of chronic rhinosinusitis nasal polyps (CRSwNP). Nasal steroids mainly recommended therapeutics in treatment disease, besides their beneficial effects, they may worsen osteitis via osteopenia. This study aimed to search for coalescence CRSwNP steroid use (NSU). Methods A cross-sectional wa...

The wireless sensor network (WSN) is typically comprised many tiny nodes equipped with processors, sender/receiver antenna and limited battery in which it is impossible or not economic to recharge. Meanwhile, network lifespan is one of the most critical issues because of limited and not renewal used battery in WSN. Several mechanisms have been proposed to prolong network lifespan such as LEACH,...

introduction: ureaplasma uriealyticum is one of the most important causes of nongonococcal and nonspecific urethritis (ngu & nsu) in men. mycoplasma hominis too has a causal role in ngu & nsu. this study aimed to investigate whether it is possible to detect mycoplasma hominis and ureaplasma uriealyticum in first voided urine samples in men suffering from ngu & nsu without complaints of urethral...
