Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Interplanetary Particle Environment. Proceedings of a Conference [PDF]
A workshop entitled the Interplanetary Charged Particle Environment was held at the Jet Propulsion Laboratory (JPL) on March 16 and 17, 1987. The purpose of the Workshop was to define the environment that will be seen by spacecraft operating in the 1990s.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Estimation method for bit upset ratio of NAND flash memory induced by heavy ion irradiation
AIP AdvancesIn order to estimate the bit upset ratio of NAND flash memory induced by heavy ion irradiation, starting from the physical mechanism of the bit upset of NAND flash memory, an analytical model based on statistical methods was developed to describe the ...

Radiation Hardened NULL Convention Logic Asynchronous Circuit Design
Journal of Low Power Electronics and Applications, 2015 This paper proposes a radiation hardened NULL Convention Logic (NCL) architecture that can recover from a single event latchup (SEL) or single event upset (SEU) fault without deadlock or any data loss.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.
