A wavelet modulation method for a quasi-Z-source inverter
工程科学学报, 2017 A wavelet modulation strategy applied to a quasi-Z-source inverter was proposed. The regulating range of the shootthrough duty ratio could be increased by changing the locations of the sampling points set using traditional wavelet-modulation.

Modulating autophagy: a strategy for cancer therapy [PDF]
Chinese Journal of Cancer, 2011 Autophagy is a process in which long-lived proteins, damaged cell organelles, and other cellular particles are sequestered and degraded. This process is important for maintaining the cellular microenvironment when the cell is under stress. Many studies have shown that autophagy plays a complex role in human diseases, especially in cancer, where it is ...

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Switching Modulation Strategies for Multilevel Inverter
ELEKTRIKA- Journal of Electrical Engineering, 2021 There is always a need to create efficient and optimized converters to deliver the best possible results to achieve a better THD profile in the waveform output. One way is by controlling the switching of the power switches of the converters using appropriate modulation schemes.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Novel Hybrid Modulation Method for Modular Multilevel Converter Based Energy Storage System
IEEE Access, 2023 This paper focuses on introducing a modular cascaded battery energy storage system and establishing a mathematical model for both the AC and DC sides of the energy storage system. Based on this, a corresponding control strategy is proposed.

A Seven-level defined selective harmonic elimination PWM strategy [PDF]
, 2006 Selective harmonic elimination pulse-width modulation (SHE-PWM) techniques offer an optimized control approach for a given converter and are therefore suitable for the low switching frequency high-power applications.
