A Classical Molecular Dynamics Study on the Effect of Si/Al Ratio and Silanol Nest Defects on Water Diffusion in Zeolite HY
The diffusion of water confined in zeolite HY has been studied using classical molecular dynamics at 300 K to probe the effects of water loading, Si/Al ratio, and silanol nest defect presence on the behavior of water confined...
Spectral Gap in Mean-Field O(n) -Model
Abstract We study the dependence of the spectral gap for the generator of the Ginzburg–Landau dynamics for all$$\mathcal...

Alternatives to Traditional Per-Oral Endoscopy for Screening.
Barrett's esophagus (BE) predisposes patients to esophageal adenocarcinoma. 3 to 6% of individuals with gastro-esophageal reflux disease are estimated to have BE but only 20 to 25% of BE patients are currently diagnosed. The...
Ruthenium-catalyzed <i>O</i>- to S-alkyl migration
A practical ruthenium-catalyzed O- to S-alkyl migration affords structurally diverse thiooxazolidinones in excellent yields. Our studies suggest this catalytic transformation proceeds through a pseudoreversible radical...
Short-Term Response of Cytosolic N O 3 - to Inorganic Carbon Increase in Posidonia oceanica Leaf Cells.
The concentration of CO2 in the atmosphere has increased over the past 200 years and is expected to continue rising in the next 50 years at a rate of 3 ppm·year-1. This increase has led to a decrease in seawater pH that has...

Improved bounds for the Erdős-Rogers function
The Erd\H{o}s-Rogers function $f_{s,t}$ measures how large a $K_s$-free
induced subgraph there must be in a $K_t$-free graph on $n$ vertices. While
good estimates for $f_{s,t}$ are known for some pairs $(s,t)$, notably...
Horizontally acquired divergent O-antigen contributes to escape from cross-immunity in the classical bordetellae

Background:
Horizontal gene transfer (HGT) allows for rapid spread of genetic material between species, increasing genetic and phenotypic diversity. Although HGT contributes to adaptation and is widespread in many bacteria...
