Peptide‐based ligand antagonists block a Vibrio cholerae adhesin
FEBS Letters, EarlyView.The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Continuous spectrum of a fourth order nonhomogeneous differential operators with variable exponent
Electronic Journal of Qualitative Theory of Differential Equations, 2013 In this article, we consider the nonlinear eigenvalue problem: $$\left\{ \begin{array}{ll} \Delta(|\Delta u|^{p_1(x)-2}\Delta u)+\Delta(|\Delta u|^{p_2(x)-2}\Delta u)=\lambda|u|^{q(x)-2}u,\ {\rm in}\ \Omega, & \\ u=\Delta u=0,\ {\rm on ...

Quantum Critical Points-Experiments
, 1998 We review experiments on Li(Ho,Tb)pY1-pF4 which test ideas about quantum critical phenomena in the clean (ferromagnetic) and disordered (spin glass) limits. The outstanding problem of the ‘anti-glass’ discovered for p=0.045 is also described. Finally, we point out the ubiquity of quantum critical points in condensed matter physics.

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Critical points of an invariant function may or may not be symmetric. We prove, however, that if a symmetric critical point exists, those adjacent to it are generically symmetry breaking. This mathematical mechanism is shown to carry important implications for our ability to efficiently minimize invariant nonconvex functions, in particular those ...

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer
FEBS Letters, EarlyView.Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Existence of solutions to fractional Hamiltonian systems with combined nonlinearities
Electronic Journal of Differential Equations, 2016 This article concerns the existence of solutions for the fractional Hamiltonian system $$\displaylines{ - _tD^{\alpha}_{\infty}\big(_{-\infty}D^{\alpha}_{t}u(t)\big) -L(t)u(t)+\nabla W(t,u(t))=0,\cr u\in H^{\alpha}(\mathbb{R},\mathbb{R}^n ...
