Dispersion of Klauder's temporally stable coherent states for the hydrogen atom

, 1998
We study the dispersion of the "temporally stable" coherent states for the hydrogen atom introduced by Klauder. These are states which under temporal evolution by the hydrogen atom Hamiltonian retain their coherence properties.

Intra- and intermolecular proton transfer in 2,6-diaminopyridinium 4-hydroxypyridin-1-ium-2,6-dicarboxylate [PDF]

, 2012
Chelidamic acid (4-hydroxypyridine-2,6-dicarboxylic acid) and 2,6-diaminopyridine react to form the title salt, C5H8N3+·C7H4NO5-; there are two formula units in the asymmetric unit.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

FEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Optical deceleration of atomic hydrogen

New Journal of Physics, 2022
Abstract We demonstrate control over the motional degrees of freedom of a cryogenic hydrogen atomic beam using an accelerating optical lattice. For our method, we load metastable atoms from a cryogenic beam into a moving optical lattice, decelerate the lattice, and observe a commensurate deceleration of the atoms. For this demonstration,

Perturbation hydrogen-atom spectrum in deformed space with minimal length

, 2006
We study energy spectrum for hydrogen atom with deformed Heisenberg algebra leading to minimal length. We develop correct perturbation theory free of divergences.

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

FEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...

Intense field stabilization in circular polarization: 3D time-dependent dynamics [PDF]

, 2001
We investigate the stabilization of a hydrogen atom in circularly polarized laser fields. We use a time-dependent, fully three dimensional approach to study the quantum dynamics of the hydrogen atom subject to high intensity, short wavelength laser ...

In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

FEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Chlorido(4-methylpyridin-2-amine-κN1)(2-{[(4-methylpyridin-2-yl)imino-κN]methyl}phenolato-κO)copper(II)

Acta Crystallographica Section E, 2012
In the title complex, [Cu(C13H11N2O)Cl(C6H8N2)], the CuII atom adopts a distorted tetrahedral geometry being coordinated by the phenolic O atom and the azomethine N atom of the Schiff base ligand N-salicylidene 2-aminopyridine, and by the 2-aminopyridine
