OBJECTIVES Behavioral interventions are effective strategies for HIV/AIDS prevention and control. However, implementation of such strategies relies heavily on the accurate estimation of the high-risk population size. The multiplier method and generalized network scale-up method were recommended to estimate the population size of those at high risk for HIV by UNAIDS/WHO in 2003 and 2010, respect...

Single-image haze removal is a challenging ill-posed problem. Recently, methods based on training synthetic data have achieved good dehazing results. However, we note that these can be further improved. A novel deep learning-based method proposed to obtain better-dehazed result for single-image in this paper. Specially, propose dual multi-scale network learn the knowledge from synthetical data....

Most randomized controlled trials (RCT) of social programs test interventions at modest scale. While the hope is that promising programs will be scaled up, there are few successful examples of this scale-up process in practice. It would be ideal to know which programs will work at large scale before investing the resources to take them to scale. But it would seem that the only way to tell wheth...

I n the past, only major Internet players such as Amazon, eBay, and Google were interested in deploying large-scale Web services. However , this is changing rapidly—all sorts of companies and governmental organizations are suddenly looking towards Web services as a platform that might support a wide range of demanding applications. Examples of such systems include big banking and brokerage data...

Sicklepod (Senna obtusifolia L., Fabaceae) is a leguminous plant that thrives unwanted in crop fields such as soybean farms and is therefore described as a weed especially in many Southeastern States in the US. Although the recent introduction of “round-up-ready” soybeans mitigates infestation of the beans by sicklepod, the latter is so prolific that even volunteer stands yield over a 1120 kg/h...
