In biology, many RNA molecules act as sophisticated microscopic machines. Among them, riboswitches function as tiny biological sensors, changing their 3D shape upon binding to a specific metabolite.
Abstract: Under the high-frequency and high-dv/dt pulse excitation of SiC inverter, hairpin winding (HW) is susceptible to nonuniform voltage stress, which will threaten its insulation reliability.
In the summer of 1976, the UK basked in a record-breaking ten-week heatwave. Looking back at photos of sunbathers thronging the parks and beaches, one thing leaps out: almost everyone was slim. Among ...
Abstract: The wound field flux modulation machine (WFFMM) suffers from DC winding induced voltage pulsation, which can introduce pulsation in the DC winding current, deteriorate the machine ...
