The Analysis on Space Radiation Environment and Effect of the KOMPSAT-2 Spacecraft(I): Total Ionizing Dose Effect [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2001
In this paper, space radiation environment and total ionizing dose(TID) effect have been analyzed for the KOMPSAT-2 operational orbit. It has been revealed that the trapped protons are concentrated in the SAA(South Atlantic Anomaly) area and that the ...

Total ionizing dose effect of 0.18 m nMOSFETs

open access: yesActa Physica Sinica, 2011
A 0.18 m MOSFET with shallow trench isolation is exposed to a -ray radiation. The parameters such as off-state leakage current, threshold voltage, transconductance, gate leakage current, and subthreshold slope are analyzed for pre- and post-irradiation. By introducing constant sheet charges at the shallow trench isolation oxide sidewall, good agreement

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

open access: yesFEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).

Pioneering evaluation of GaN transistors in geostationary satellites

open access: yesScientific Reports, 2022
In this paper, we present the results of a 6-year experiment in space that studied the effects of radiation in Gallium Nitride (GaN) electronics in geostationary orbit.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

open access: yesFEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Influence of enhanced low dose rate sensitivity on single-event transient degradation in the LM158 bipolar operational amplifier

open access: yesAIP Advances, 2021
The synergistic effect of enhanced low dose rate sensitivity and single-event transients (SETs) in the bipolar dual operational amplifier LM158 is studied.

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Static and Dynamic Radiation Damage of Silicon Carbide VDMOS and Their Comparison

open access: yesYuanzineng kexue jishu, 2022
The dynamic characteristics of silicon carbide VDMOS (SiC VDMOS) with different bias states under total dose radiation environment were studied. The effects of 60Co γ ray irradiation on the threshold voltage and switching characteristics of SiC VDMOS ...

Discerning protein pools by selective staining with self‐labeling tags

open access: yesFEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.
