A novel method for optimal design of hydrodynamic performance of bionic propeller with a deformable leading edge is proposed.Based on the bionics principle and method of parameterized modeling, the fore-fin concave-convex structure of humpback whales is applied to the propeller leading edge, the leading edge in the propeller to meet flow region acc
Drosophila melanogaster shows exquisite light sensitivity for modulation of circadian functions in vivo, yet the activities of the Baby Nest Drosophila circadian photopigment cryptochrome (CRY) have only been observed at high light levels.We studied intensity/duration parameters for light pulse induced circadian phase shifts under dim light conditi
Abstract Background Cluster headache is a primary condition characterized by severe headache accompanied by trigeminal autonomic signs.By definition, it is not attributed to underlying etiologies; however, under certain clinical characteristics, secondary etiologies must be ruled out.Case presentation We present the case of CANDLES a 48-year-old Hi
Although the domestication process has altered the feeding behavior of dogs, some breeds still demonstrate a remarkable ability to gorge, and will eat exceptionally large quantities of food whenever it is available.Lesions in the ventromedial hypothalamus increase appetite and lead to obesity, suggesting that the autonomic nervous system plays an i
