Schr\"odinger operators on the half line: Resolvent expansions and the Fermi golden rule at thresholds [PDF]

, 2005
We consider Schr\"odinger operators $H=- \d^2/\d r^2+V$ on $L^2([0,\infty))$ with the Dirichlet boundary condition. The potential $V$ may be local or non-local, with polynomial decay at infinity.

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

A Hybrid Proximal Point Three-Step Algorithm for Nonlinear Set-Valued Quasi-Variational Inclusions System Involving (A,η)-Accretive Mappings

Fixed Point Theory and Applications, 2010
The main purpose of this paper is to introduce and study a new class of generalized nonlinear set-valued quasi-variational inclusions system involving (A,η)-accretive mappings in Banach spaces.

Third Class Resolver: a retrospective analysis.

European journal of paediatric dentistry, 2014
To evaluate the use of Third Class Resolver (TCR), a new fixed and functional orthopaedic appliance for the treatment of skeletal Class III malocclusion in adolescents and young adults.Study design: Retrospective analysis. Twenty subjects, 10 females and 10 males, affected by Class III malocclusion were treated with a new fixed orthopaedic appliance ...

Spatially Resolved Analysis of Bragg Selectivity [PDF]

Applied Sciences, 2015
This paper targets an inherent control of optical shrinkage in photosensitive polymers, contributing by means of spatially resolved analysis of volume holographic phase gratings. Point by point scanning of the local material response to the Gaussian intensity distribution of the recording beams is accomplished.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

FEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

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 ...

Feedback stabilization of a coupled string-beam system

Networks and Heterogeneous Media, 2009
We consider a stabilization problemfor a coupled string-beam system. We prove some decay results of the energy of the system. Themethod used is based on the methodology introduced in Ammari and Tucsnak [2] where the exponential and weak stability for the

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

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 ...

Algorithms for Solving System of Extended General Variational Inclusions and Fixed Points Problems

Abstract and Applied Analysis, 2012
We introduce a new system of extended general nonlinear variational inclusions with different nonlinear operators and establish the equivalence between the aforesaid system and the fixed point problem.
