Cold binary atomic collisions in a light field

Journal of Research of the National Institute of Standards and Technology, 1996
The rate coefficients are calculated for trap loss due to excited state formation during s-wave collisions of two atoms in a light field in a cold atomic gas near conditions for formation of a Bose-Einstein condensate. Blue detuning from the allowed atomic resonance transition causes excitation of a replusive molecular potential, whereas red detuning ...

Icariin Enhances the Enzymatic Activity of N‐acetylgalactosaminidase to Augment Akkermansia Abundance in Gut Microbiota for Improved PD‐1 Blockade Efficacy in Tumor Suppression

Advanced Science, EarlyView.
Icariin promoted the growth of Akk by enhancing the activity of N‐acetylgalactosaminidase (Amuc_0920), which enhanced mucin utilization and provided a favorable nutrient environment for bacterial growth. This icariin‐mediated enrichment of Akk further reshaped the tumor microenvironment and promoted CD8+ T cell infiltration, ultimately synergizing with

Open heavy flavor measurements in d+Au collisions at PHENIX experiment

EPJ Web of Conferences, 2014
The heavy quarks produced in the early stage of heavy-ion collisions are very effective probes of the dense partonic medium produced at RHIC. PHENIX has the ability to measure heavy quark production through single electrons in the central arm ...

Towards sympathetic cooling of large molecules: Cold collisions between benzene and rare gas atoms

, 2009
This paper reports on calculations of collisional cross sections for the complexes Z-CDH6 (X = 3He, 4He, Ne) at temperatures in the range 1)μK - 10K and shows that relatively large cross sections in the 103-105Å2 range are available for collisional ...

Astrocytic Phenotypic Switching in Posterior Piriform Cortex Orchestrates Bone Cancer Pain–Depression Comorbidity via Purinergic–Noradrenergic Signaling

Advanced Science, EarlyView.
Bone cancer pain and depression share a common origin: astrocytic A2‐to‐A1 transition in the posterior piriform cortex. This phenotypic shift disrupts the ATP–adenosine–A2AR–norepinephrine axis, simultaneously driving nociceptive and affective dysfunction.

J/ψ suppression and low mass dileptons in the NA60 experiment

EPJ Web of Conferences, 2010
The NA60 experiment, at CERN SPS, has studied muon pairs production in p-A and A-A collisions at 158 GeV. After an introduction to explain why the dimuon measurements are a useful tool to investigate the formation of a deconfined medium and how these ...

Observation of electron cyclotron harmonic emissions due to electrostatic instabilities in mirror-confined plasma

Physical Review Research, 2020
Electron cyclotron instabilities are of fundamental importance in space and laboratory plasmas having nonthermal electron distribution functions. Observations are reported of electromagnetic emissions at electron cyclotron harmonics in a mirror-confined ...

Hydrogen (H2) Recovery From Hydrogen Sulfide (H2S): Current Technologies, Challenges, and Future Outlook

Advanced Science, EarlyView.
ABSTRACT Hydrogen sulfide (H2S) can be transformed into hydrogen (H2) through several chemical and catalytic processes, offering a promising route for both waste treatment and clean H2 production. This colorless, flammable, and toxic gas is found abundantly in swamps, volcanoes, hot springs, sewages, other natural gas fields, and even in refineries and

Quarkonium suppression in heavy-ion collisions from coherent energy loss in cold nuclear matter

, 2014
International audienceThe effect of parton energy loss in cold nuclear matter on the suppression ofquarkonia (J/psi, Upsilon) in heavy-ion collisions is investigated, byextrapolating a model based on coherent radiative energy loss recently shown ...
