A pedestrian who was hit and killed by a driver over the weekend in San Jose has been identified as Qinghua Liu, 79, of San Jose, according to the Santa Clara County Medical Examiner-Coroner’s Office.
Findings showed the probability of achieving total remission was significantly greater in the corticosteroid pulse group compared to the oral corticosteroid group.
Scientists identified a signaling pathway within brain cells that regulates how long and how deeply we sleep. A good night's sleep can work wonders for both mind and body. But what is it that determines how much we need to sleep, and what can cause us to sleep more deeply? In a new study, rese

The way people walk while carrying their smart devices could help to improve the mapping of indoor areas poorly served by GPS.
As global positioning systems (GPS) become more advanced, they still face a challenge. Though they function well outdoors, location-based services (LBS) still struggle to map indoor locations reliably. A paper published in the open-access journal Mobile Information Systems entitled Multimode Pedestrian Dead Reckoning Gait Detection Algorithm Based on Identification of Pedestrian Phone Carrying Position tackles this problem by investigating how we carry our smartphones and how this affects our gait.
The authors, including Ying Guo and Qinghua Liu from Shandong University of Science and Technology, China, used these factors to find a way to improve algorithms used in pedestrian dead reckoning (PDR). PDR is an internal phone navigation system and currently one of the primary methods used for mapping locations t
