A Novel Super Transistor-Based High-Performance CCII and Its Applications
Elektronika ir Elektrotechnika, 2018 In this paper a high-performance low-voltage low-power CMOS second-generation current conveyor (CCII) is presented. The proposed CCII is based on super transistor (ST) and enables low input impedance at X terminal and high output impedance at Z terminal.

A High-Performance SiC Super-Junction MOSFET With a Step-Doping Profile
IEEE Journal of the Electron Devices Society, 2021 In this article, we investigate a 4H-SiC super- junction (SJ) MOSFET structure with a charge-imbalance doping-profile. According to our numerical simulations and comparisons with the conventional SiC VDMOS (C-VDMOS) and SiC SJ VDMOS (SJ-VDMOS) devices ...

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.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

An Improved 4H-SiC Trench MOS Barrier Schottky Diode With Lower On-Resistance
IEEE Access, 2019 An improved 4H-SiC trench MOS barrier Schottky (TMBS) structure that can significantly reduce the specific on-resistance ( $R_{on,sp}$ ) is proposed in this paper.

Molecular Oncology, EarlyView.Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...
