Methods for Analyzing Avionics Reliability Reflecting Atmospheric Radiation in the Preliminary Development Phase: An Integrated Failure Rate Analysis

Aerospace
Advances in deep submicron semiconductor technology have increased the significance of studying soft errors caused by atmospheric radiation in avionics systems. Atmospheric radiation particles, such as protons and neutrons, can induce Single Event Upsets

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Low-Power Radiation-Hardened Static Random Access Memory with Enhanced Read Stability for Space Applications

Applied Sciences
In space environments, radiation particles affect the stored values of SRAM cells, and these effects, such as single-event upsets (SEUs) and single-event multiple-node upsets (SEMNUs), pose a threat to the reliability of systems used in the space ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Radiation Environment-Constrained FPGA Reinforcement Technology and Reliability Research Utilizing Error Control Coding

IEEE Access
In the radiation work environment of nuclear power plants and similar facilities, radiation can induce Single Event Upsets (SEUs) and even Multiple Bit Upsets (MBUs) in Field-Programmable Gate Arrays (FPGAs) and related devices.

Mutual interference induced by single event effects in CMOS circuits

AIP Advances, 2020
Single event effect (SEE) induced mutual interference in CMOS circuits, including single event (SE) induced coupling effects (crosstalk) and modulation in local supply voltage on power-supply rails, was studied based on the increase in metal interconnect

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Compiler Optimizations Impact the Reliability of the Control-Flow of Radiation-Hardened Software

Journal of Aerospace Technology and Management, 2013
http://dx.doi.org/10.5028/jatm.v5i3.224 This paper discusses how compiler optimizations influence software reliability when the optimized application is compiled with a technique to enable the software itself to detect and correct radiation-induced ...
