Among M-phase shift keying (M-PSK) schemes, quadrature phase-shift keying (QPSK) is used most often because of its efficient bandwidth consumption.However, in comparison with minimum-shift keying, which has continuous phase transitions, QPSK requires a higher bandwidth to transmit a signal.This article focuses on the phase transitions in QPSK signa

The two-speed automatic transmission can adjust the drive motor speed of electric vehicles and expand their output torque range.This study proposes a rule-based partitioned gear-shifting strategy for pure electric vehicles equipped with a Solar Power two-speed dual-clutch transmission, combining economic and dynamic shifting strategies to ensure lo
In the past twenty years, the consumption of opioid medications has reached significant proportions, leading to a rise in drug misuse and abuse and increased opioid dependence and related fatalities.Thus, the purpose of this study was to determine whether there are pharmacovigilance signals of abuse, misuse, and dependence and their nature for the
