New modulation scheme for bidirectional qZS modular multi-level converters

open access: yesThe Journal of Engineering, 2019
This study proposes a dedicated modulation scheme for a bidirectional quasi-Z-source (qZS) modular multi-level converter. The operation principle and a suitable pulse-width modulation method are proposed.

Computer-aided simulation of power MOSFET switch-mode convertors

open access: yesElectronics Letters, 1984
A computer-aided modelling procedure for power MOSFET switching convertors is reported. Results show dynamic turn-on and turn-off device waveforms, peak stresses, switching trajectory and transient switching losses. Excellent agreement is demonstrated between predicted and measured switching characteristics on an experimental high-frequency high ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

open access: yesFEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...
