RHLP-18T: A Radiation-Hardened 18T SRAM with Enhanced Read Stability and Low Power Consumption

Applied Sciences
Electronic equipment in space is constantly exposed to high-energy particles, which can induce Single Event Upsets (SEUs) in memory components, threatening system reliability.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Application of the Nuclear Microprobe to the Imaging of Single Event Upsets in Integrated Circuits [PDF]

, 1991
A new form of microscopy has been developed which produces micron-resolution maps of where single event upsets occur during ion irradiation of integrated circuits.

Proton-Induced Upsets in 41-nm NAND Floating Gate Cells

, 2012
The corruption of floating gate bits due to high-energy protons is analyzed in 41-nm single level NAND Flash memories. Proton-induced upsets at low doses are not negligible in deeply-scaled single-level cell Flash memories, due to a combination of direct

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Algorithm of SEU Rate Prediction Inside Spacecrafts [PDF]

Journal of Astronomy and Space Sciences, 1996
One of the important effects of the space environment on the satellites and spacecrafts is the single event upsets (SEUs) which are caused by the high energy particles in space.

Single Event Effects in 90-nm Phase Change Memories

, 2011
Single event effects are investigated in 90-nm phase change memories. The cells are shown to be insensitive to heavy-ion strikes and will likely remain so for a few more generations.
