Abstract A power processing system (PPS) with a seven‐level dual‐buck inverter (SLDBI) for a photovoltaic (PV) power generation system is proposed. The PPS is comprised of a boost power converter and an SLDBI. The boost power converter matches th

This paper presents the design of a 10 GHz dual-loop PLL with active cycle-jitter correction. In the main loop of the PLL, a sampling PD is utilized to suppress the in-band noise to reach the reference noise floor. On the other hand, to eliminate noi

Starting by revisiting Special Relativity, here we provide a reliable characterization of the entire 4-dimensional fundamental structures in our reality where the frame of discrete tangent space of $F^{1,3}$ is quantized to massless, zero-momentum pa

In order to provide early selection indicators for the breeding of plants used for producing tea seed oil or harvesting tea, we investigated the relationships between flower morphology and fruit yields in tea plants. We analyzed 106 tea varieties to

Serially connected statically balanced manipulators with springs have been used in many applications. However, a portion of the torques caused by springs countering each other lead to an imbalance in gravitational torques and, therefore, are deemed a

Most female meiotic spindles undergo striking morphological changes while transitioning from metaphase to anaphase. The ultra-structure of meiotic spindles, and how changes to this structure correlate with such dramatic spindle rearrangements remains
