Reexamining Black-Body Shifts for Hydrogenlike Ions [PDF]

open access: yes, 2008
We investigate black-body induced energy shifts for low-lying levels of atomic systems, with a special emphasis on transitions used in current and planned high-precision experiments on atomic hydrogen and ionized helium.

Heterodyne non-demolition measurements on cold atomic samples: towards the preparation of non-classical states for atom interferometry [PDF]

open access: yes, 2011
We report on a novel experiment to generate non-classical atomic states via quantum non-demolition (QND) measurements on cold atomic samples prepared in a high finesse ring cavity.

The optimization of the multi-atmospheric Ar-Xe laser [PDF]

open access: yes, 1998
The quasi-steady-state conditions of the multi-atmospheric e-beam sustained Ar-Xe laser are investigated. It is observed that the duration of the stationary period depends on the e-beam current, discharge power deposition, and gas pressure.

Benchmarking a first-principles thermal neutron scattering law for water ice with a diffusion experiment

open access: yesEPJ Web of Conferences, 2017
The neutron scattering properties of water ice are of interest to the nuclear criticality safety community for the transport and storage of nuclear materials in cold environments.

Clique‐width: Harnessing the power of atoms [PDF]

open access: yesJournal of Graph Theory, 2020
AbstractMany NP‐complete graph problems are polynomial‐time solvable on graph classes of bounded clique‐width. Several of these problems are polynomial‐time solvable on a hereditary graph class if they are so on the atoms (graphs with no clique cut‐set) of .

Investigation on ultimate strength of thin wall tee pipe for sodium cooled fast reactor under seismic loading

open access: yesMechanical Engineering Journal, 2016
It is important to investigate the failure mode and ultimate strength of piping components in order to evaluate the seismic integrity of piping. Many failure tests of thick wall and high pressure piping for Light Water Reactors (LWRs) have been ...

Self-Channeling of High-Power Long-Wave Infrared Pulses in Atomic Gases.

open access: yesPhysical Review Letters, 2017
We simulate and elucidate the self-channeling of high-power 10  μm infrared pulses in atomic gases. The major new result is that the peak intensity can remain remarkably stable over many Rayleigh ranges.

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

open access: yesFEBS 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 ...
