Inductors used for power supplies can be miniaturized by increasing the frequency. However, as the frequency increases, the loss in the inductor increases, which hinders the improvement of efficiency. This study suggests a flux path control technology as a method for reducing inductor loss....

During the last decade, commercial banana cropping has spread widely and rapidly in tropical China. In the present study, we focus on a Dai village to identify how villagers adopted commercial banana cropping and examine the conditions that might sustain this change. The results show that the...

Field measurements conducted 4 years after the construction of a new portion of the Weixi–Shangri-La road in Yunnan, China, reveal that unprecedented rates of mass wasting occurred along the road with much of this sediment directly impacting the headwaters of the Mekong River. Landslide...
