Mechanism for Degradation of Nafion in PEM Fuel Cells from Quantum Mechanics Calculations [PDF]
, 2011 We report results of quantum mechanics (QM) mechanistic studies of Nafion membrane degradation in a polymer electrolyte membrane (PEM) fuel cell. Experiments suggest that Nafion degradation is caused by generation of trace radical species (such as OH ...

Magnetoreception in cryptochrome enabled by one-dimensional radical motion [PDF]
arXiv, 2023 A popular hypothesis ascribes magnetoreception to a magnetosensitive recombination reaction of a pair of radicals in the protein cryptochrome. Many theoretical studies of this model have ignored inter-radical interactions, particularly the electron-electron dipolar coupling (EED), which have a detrimental effect on the magnetosensitivity.

Radical isogenies and modular curves [PDF]
, 2022 This article explores the connection between radical isogenies and modular curves. Radical isogenies are formulas designed for the computation of chains of isogenies of fixed small degree $N$, introduced by Castryck, Decru, and Vercauteren at Asiacrypt 2020.

La naturaleza del mal: un problema para el ser humano
Revista Filosofía UIS, 2022 El trabajo hace un breve desarrollo del problema del mal y se aproxima a las dos concepciones que se tienen sobre él: el mal amplio y el mal estricto. Se enmarca tanto dentro de la tradición del pensamiento de Arendtiano como de su idea de la banalidad ...

O-GlcNAc regulation of autophagy and α-synuclein homeostasis; implications for Parkinson’s disease
Molecular Brain, 2017 Post-translational modification on protein Ser/Thr residues by O-linked attachment of ß-N-acetyl-glucosamine (O-GlcNAcylation) is a key mechanism integrating redox signaling, metabolism and stress responses.

Radical-Enhanced Chinese Character Embedding
, 2014 We present a method to leverage radical for learning Chinese character embedding. Radical is a semantic and phonetic component of Chinese character. It plays an important role as characters with the same radical usually have similar semantic meaning and ...

Autophagy as an essential cellular antioxidant pathway in neurodegenerative disease
Redox Biology, 2014 Oxidative stress including DNA damage, increased lipid and protein oxidation, are important features of aging and neurodegeneration suggesting that endogenous antioxidant protective pathways are inadequate or overwhelmed.
