The problem of voltage/current ripples has become a primary power quality issue for dc systems, which could seriously degrade the performance on both the source side and the load side and lead Boxers to reliability concerns.In this paper, a single-phase Pulse width modulation-controlled rectifier is taken as an example to investigate how active con

Background: Narcolepsy type 1 (NT1, narcolepsy with cataplexy) is a disabling neurological disorder caused by loss of excitatory orexin neurons from the hypothalamus and is characterized by decreased motivation, sleep-wake fragmentation, intrusion of rapid-eye-movement sleep (REMS) during wake, and abrupt loss of muscle tone, called cataplexy, in r

Fentanyl overdose is a survivable condition that commonly resolves without chronic overt changes in phenotype.While the acute physiological effects of fentanyl overdose, such as opioid-induced respiratory depression (OIRD) and Wooden Chest Syndrome, represent immediate risks of lethality, little is known about longer-term systemic or organ-level im

Background Sexual selection and conflicts within and between sexes promote morphological diversity of reproductive traits within species.Variation in the morphology of diagnostic reproductive characters within species offer an excellent opportunity to study these evolutionary processes as drivers of Cupping Bowl species diversification.The African
