The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

open access: yesMolecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

The orthosymplectic superalgebra in harmonic analysis [PDF]

open access: yes, 2012
We introduce the orthosymplectic superalgebra osp(m|2n) as the algebra of Killing vector fields on Riemannian superspace R^{m|2n} which stabilize the origin. The Laplace operator and norm squared on R^{m|2n}, which generate sl(2), are orthosymplectically

Dynamic transition in Landau-Zener-St\"uckelberg interferometry of dissipative systems: the case of the flux qubit [PDF]

open access: yes, 2016
We study Landau-Zener-Stuckelberg (LZS) interferometry in multilevel systems coupled to an Ohmic quantum bath. We consider the case of superconducting flux qubits driven by a dc+ac magnetic fields, but our results can apply to other similar systems.

Virulence Regulation and Lifestyle Transitions: The Role of c‐di‐GMP and Two‐Component Systems in Erwinia amylovora and Their Evolutionary Context Within Enterobacterales

open access: yesMolecular Plant Pathology, Volume 27, Issue 2, February 2026.
Erwinia amylovora infects apple blossoms by activating the T3SS, then spreads systemically via amylovoran‐mediated biofilms. Transitions between motile and sessile states are regulated by key two‐component systems and c‐di‐GMP. This review summarises infection biology, virulence factors, regulatory networks and evolutionary insights underlying fire ...

Matrix-Monotonic Optimization for MIMO Systems [PDF]

open access: yes, 2014
For MIMO systems, due to the deployment of multiple antennas at both the transmitter and the receiver, the design variables e.g., precoders, equalizers, training sequences, etc. are usually matrices.

Determination of heat transfer coefficient for hot stamping process [PDF]

open access: yes, 2015
© 2015 The Authors.The selection of the heat transfer coefficient is one of the most important factors that determine the reliability of FE simulation results of a hot stamping process, in which the formed component is held within cold dies until fully ...

Dual‐Pathway Defense: Ultramicro‐Pulverised Powder of Polygonum chinense L. and Atractylodes rhizome (PAUP) Rescues Broilers From E. coli‐Triggered Liver Injury Through Modulation of Oxidative Stress and Inflammation

open access: yesFood Science &Nutrition, Volume 14, Issue 1, January 2026.
Reduced Antibiotic residues and resistance concerns: Offers a potential natural alternative to antibiotics for combating E. coli infections in poultry. Provided safer poultry food products: By enhancing liver function, restoring weight gain, and improving feed efficiency, PAUP supports the production of healthier chickens, ultimately contributing to ...

Moraxella catarrhalis Expresses an Unusual Hfq Protein [PDF]

open access: yesInfection and Immunity, 2008
ABSTRACT The Hfq protein is recognized as a global regulatory molecule that facilitates certain RNA-RNA interactions in bacteria. BLAST analysis identified a 630-nucleotide open reading frame in the genome of Moraxella catarrhalis ATCC 43617 that was highly conserved among M. catarrhalis

A Small RNA Derived From the 5′ End of the IS200 tnpA Transcript Regulates Multiple Virulence Regulons in Salmonella typhimurium

open access: yesMolecular Microbiology, Volume 124, Issue 5, Page 413-432, November 2025.
We show deletion of an IS200‐encoded sRNA (5′tnpA) in Salmonella impacts the expression of SPI‐1, flagellar, cysteine, and phsABC regulons. Evidence is presented that, with regard to the SPI‐1 regulon, 5′tnpA may function through base pairing with another sRNA known to regulate SPI1 called PinT.

Estimating the risk of adverse birth outcomes in pregnant women undergoing non-obstetric surgery using routinely collected NHS data: an observational study [PDF]

open access: yes, 2016
Background: Previous research suggests that non-obstetric surgery is carried out in 1 – 2% of all pregnancies. However, there is limited evidence quantifying the associated risks.
