Vacuum Ultraviolet Fourier-transform Spectroscopy of <sup>16</sup>O and <sup>18</sup>O
Abstract
A spectroscopic study of atomic oxygen (O i ) is performed using the Fourier-transform vacuum ultraviolet (VUV) spectrometer at the Dichroïsme Et...
Formyloxyacetoxyphenylmethane and 1,1-diacylals as versatile O-formylating and O-acylating reagents for alcohols
Formyloxyacetoxyphenylmethane, symmetric 1,1-diacylals and mixed 1-pivaloxy-1-acyloxy-1-phenylmethanes have been used as moisture stable O-formylating and O-acylating reagents for primary and secondary alcohols, allylic alcohols...

O-Antigen-Dependent Colicin Insensitivity of Uropathogenic Escherichia coli.
Connor Sharp, Christine Boinett, Amy Cain, Nicholas G Housden, Sandip Kumar, Keith Turner, Julian Parkhill, Colin Kleanthous
Aug 20, 2019
The outer membrane of Gram-negative bacteria presents a significant barrier for molecules entering the cell. Nevertheless, colicins, which are antimicrobial proteins secreted by Escherichia coli, can target other E. coli cells...

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...
Precise control of Cu$_2$O nanostructures and LED-assisted photocatalysis
We describe the synthesis and characterization of a high-efficiency visible light Cu$_2$O photocatalyst. Uniform cubic, octahedral and rhombic dodecahedral Cu$_2$O nanocrystals with a size of 300–600 nm were synthesized using a...
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
Sara E Hester, Jihye Park, Laura L Goodfield, Heather A Feaga, Andrew Preston, Eric T Harvill

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...

Late, not early mismatch responses to changes in frequency are reduced or deviant in children with dyslexia
BACKGROUND: Developmental disorders of oral and written language have been linked to deficits in the processing of auditory information. However, findings have been inconsistent, both for behavioural and electrophysiological...
