Room temperature electric field controlled magnetism is extremely promising for the next-generation high-performance spintronic devices.Here, based on the ferroelectric switching driven oxygen ion migration in the Ta/Co/BiFeO3/SrRuO3 heterostructures, the magnetic moment, magnetic coercive field, exchange bias field, and junction resistance are rev
For cyclist fatalities in 2014 in Japan, the head was the most frequently injured body region.In the present study, the authors analyzed the features of cyclist head injuries in real-world traffic accidents using the data of patients who were taken to the emergency room in Dokkyo Medical University Koshigaya Hospital in Japan, from 2011 to 2013.The
This study examines listening effort, as indexed by pupil dilation, needed for processing foreign-accented speech that varies in intelligibility.Previous research has shown that the magnitude of pupil dilation is influenced by various factors, crucially the amount of noise added to speech.However, the method has not yet been used to examine foreign
