Abstract: A discrete time-domain modeling and analysis for the peak current controlled (PCC) buck light-emitting diode (LED) driver is presented in this paper. The discrete time-domain equation ...

When the microgrid is in the islanding operation mode, affected by the line impedance difference between the distributed power sources (DGs), the traditional droop control strategy will lead to the ...

Arousal may be understood on a spectrum, with excessive sleepiness, cognitive dysfunction, and inattention on one side, a wakeful state in the middle, and hypervigilance, panic, and psychosis on the ...

Multiseriate cortical sclerenchyma (MCS) is a root anatomical phenotype with utility in environments with mechanical impedance. The MCS phenotype is characterized by small cells with thick walls in ...

Improving the efficiency of root systems should result in crop varieties with better yields, requiring fewer chemical inputs, and that can grow in harsher environments. Little is known about the ...
