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 ...

Field-Plated D3mosfet Design for Breakdown Voltage Improvement

Diamond and Related Materials, 2022
As commonly reported in other power devices, the lateral deep-depletion diamond MOSFET (D3MOSFET) suffers from an electric crowding effect at the gate-edge towards the drain. This behavior leads to a premature breakdown of the gate-oxide (made of Al2O3) below the expected performances of diamond material.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Effects of Incomplete Ionization on Beta - Ga2O3 Power Devices: Unintentional Donor with Energy 110 meV

, 2017
Understanding the origin of unintentional doping in Ga2O3 is key to increasing breakdown voltages of Ga2O3 based power devices. Therefore, transport and capacitance spectroscopy studies have been performed to better understand the origin of unintentional

Electrical characterization of the soft breakdown failure mode in MgO layers [PDF]

, 2009
The soft breakdown (SBD) failure mode in 20 nm thick MgO dielectric layers grown on Si substrates was investigated. We show that during a constant voltage stress, charge trapping and progressive breakdown coexist, and that the degradation dynamics is ...

Day/night variations of myeloid and lymphoid cell subsets in the murine inguinal lymph node

FEBS Open Bio, EarlyView.
The circadian system is involved in the temporal regulation of the immune system. Our study reveals that two innate immune populations, NKT cells and neutrophils, predominate at the beginning of the day in healthy mice, highlighting how the time of day influences immune responses.

Low breakdown voltage Schottky diode as voltage regulator

Electronics Letters, 1981
Experimental evidence is given showing that Ag-n-Si Schottky diodes with resistivity about 40 mΩcm have steeper reverse breakdown characteristics than corresponding low-voltage p-n junction regulator diodes fabricated by local epitaxy. Avalanche multiplication in such a diode starts at 1.7 V, and the device has a low positive temperature coefficient of
