A Radiation-Hardened Low-Power SRAM with Enhanced Write Capability for Space Applications

Applied Sciences
With continued scaling of CMOS technology, the critical charge required for state retention in SRAM cells has decreased, leading to increased vulnerability to radiation-induced soft errors such as single-event upsets (SEUs) and single-event multi-node ...

Causal relationships between solar proton events and single event upsets for communication satellites [PDF]

, 2013
In this work, we analyze a historical archive of single event upsets (SEUs) maintained by Inmarsat, one of the world's leading providers of global mobile satellite communications services.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Overview of software tools for modeling single event upsets in microelectronic devices

Безопасность информационных технологий, 2016
The paper presents the results of the analysis of existing simulation tools for evaluation of single event upset susceptibility of microelectronic devices with deep sub-micron feature sizes. This simulation tools are meant to replace obsolete approach to

Statistical Analysis of LEO and GEO Satellite Anomalies and Space Radiation

Aerospace
Exposure to space radiation substantially degrades satellite systems, provoking severe partial or, in some extreme cases, total failures. Electrostatic discharges (ESD), single event latch-up (SEL), and single event upsets (SEU) are among the most ...

Development of the analog ASIC for multi-channel readout X-ray CCD camera

, 2011
We report on the performance of an analog application-specific integrated circuit (ASIC) developed aiming for the front-end electronics of the X-ray CCDcamera system onboard the next X-ray astronomical satellite, ASTRO-H.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells

FEBS Letters, EarlyView.
Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.

Randomness in Competitions [PDF]

, 2012
We study the effects of randomness on competitions based on an elementary random process in which there is a finite probability that a weaker team upsets a stronger team.
