Control and performance of a zero-current-switched three-phase inverter equipped with resonant circuits on the AC-side [PDF]

, 1996
This paper presents a zero-current-switched voltage-fed inverter equipped with resonant circuits on the AC side. The current flowing through a switching device, i.e., an IGBT is a sum of the load current and the resonant current.

Emerging role of ARHGAP29 in melanoma cell phenotype switching

Molecular Oncology, EarlyView.
This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

A New Fully Soft‐Switching High Step‐Up Interleaved Converter for Optimal Efficiency

IET Power Electronics
A novel fully soft‐switching interleaved high step‐up converter is introduced in this paper. The suggested converter achieves high voltage gain using coupled inductors (CI) and a voltage multiplier cell (VMC).

Analysis of Switching-Loss-Reduction Methods for MHz-Switching Buck Converters [PDF]

2007 IEEE Conference on Electron Devices and Solid-State Circuits, 2007
Numbers of switching-loss-reduction methods recently proposed for MHz-switching buck converters are thoroughly investigated. From a theoretical perspective, switching loss is found to be effectively minimized by adapting the width rather than the turn-on voltage of power transistors of a buck converter.

Intein‐based modular chimeric antigen receptor platform for specific CD19/CD20 co‐targeting

Molecular Oncology, EarlyView.
CARtein is a modular CAR platform that uses split inteins to splice antigen‐recognition modules onto a universal signaling backbone, enabling precise, scarless assembly without re‐engineering signaling domains. Deployed here against CD19 and CD20 in B‐cell malignancies, the design supports flexible multi‐antigen targeting to boost T‐cell activation and

Low-loss AlInN/GaN microwave switch

Electronics Letters, 2011
A report is presented on the first low-loss monolithic microwave integrated circuit switch using AlInN/GaN heterostructure field effect transistors. Owing to significantly lower sheet resistance compared to the conventional AlGaN/GaN heterostructure (215 against 280 Q/□), and lower contact resistance (0.27 against 0.5 Ω×mm), the microwave switch based ...
