Purpose This study aims to realize natural and effort-saving motion behavior and improve effectiveness for different operators in human–robot force cooperation. Design/methodology/approach The parameter of admittance model is identified by deep deterministic policy gradient (DDPG) to realize...

Lack of health insurance affects workers and families who depend on job-based coverage for health care. In 2007, the unemployment rate in California was 5.5%. By the end of 2009, it had more than doubled to 12.3%. This study uses data from the 2007 and 2009 California Health Interview Survey to...

Prior literature on social capital and health has predominantly focused on health outcomes and individual access to healthcare services. It is not known to what degree, if any, community social capital influences the performance or behaviors of public hospitals, a key source of healthcare for...

Migrant studies of physical activity (PA) can provide insight into the prevention of chronic disease. It is unclear, however, whether PA increases or decreases the longer migrants live in their host country. In the US, studies on immigrants' length of residence in the US and PA are inconclusive...

This article contains a new subnet training method for modular neural networks, proposed with the inspiration of the principle of “an expert with other capabilities”. The key point of this method is that a subnet learns the neighbor data sets while fulfilling its main task: learning the...

In this article, decane, methyl benzene, pyridine and acetic acid were selected as different polarity components in crude oil, and their adsorption behavior on water-wet silica surface was investigated by molecular dynamics simulation. Simulation results indicated that polar components could...
