Impact of Hfq on the intrinsic drug resistance of Salmonella enterica serovar Typhimurium
Salmonella enterica is an important enteric pathogen, and its various serovars cause both systemic and intestinal diseases in humans and domestic animals.

The X-ray Outburst of H1743-322: High-Frequency QPOs with a 3:2 Frequency Ratio
We observed the 2003 X-ray outburst of H1743-322 in a series of 130 pointed observation with RXTE. We searched individual observations for high-frequency QPOs (HFQPOs) and found only weak or marginal detections near 240 and 160 Hz.

Pleiotropic regulatory function of the RNA chaperone Hfq in the Pseudomonas protegens FD6
The rhizosphere bacterium Pseudomonas protegens FD6, which is associated with the production of antibiotics such as pyoluteorin (PLT) and 2,4-diacetylphloroglucinol (2,4-DAPG), has strong antagonistic effects on phytopathogens.

Effects of diamagnetic levitation on bacterial growth in liquid [PDF]
Diamagnetic levitation is a technique that uses a strong, spatially-varying magnetic field to levitate diamagnetic materials, such as water and biological cells. This technique has the potential to simulate aspects of weightlessness, on the Earth.

Lagrangian matching invariants for fibred four-manifolds: I
In a pair of papers, we construct invariants for smooth four-manifolds equipped with `broken fibrations' - the singular Lefschetz fibrations of Auroux, Donaldson and Katzarkov - generalising the Donaldson-Smith invariants for Lefschetz fibrations.

Hfq regulates anti-oxidative ability in Vibrio parahaemolyticus
Hfq plays a fundamental role in bacterial cell physiology. It can stimulate or repress the expression of certain target genes, and there is a possibility that Hfq regulates the oxidative stress response. However, how Hfq functions that in Vibrio parahaemolyticus remains speculative.

An upstream Hfq binding site in the fhlA mRNA leader region facilitates the OxyS-fhlA interaction.
BackgroundTo survive, bacteria must be able to adapt to environmental stresses. Small regulatory RNAs have been implicated as intermediates in a variety of stress-response pathways allowing dynamic gene regulation. The RNA binding protein Hfq facilitates

Acidic C-terminal domains autoregulate the RNA chaperone Hfq
The RNA chaperone Hfq is an Sm protein that facilitates base pairing between bacterial small RNAs (sRNAs) and mRNAs involved in stress response and pathogenesis. Hfq possesses an intrinsically disordered C-terminal domain (CTD) that may tune the function

Ultrafast Coulomb-induced dynamics of 2D magnetoexcitons
We study theoretically the ultrafast nonlinear optical response of quantum well excitons in a perpendicular magnetic field. We show that for magnetoexcitons confined to the lowest Landau levels, the third-order four-wave-mixing (FWM) polarization is ...
