Influence of electron-ion collisions on Coulomb crystallization of ultracold neutral plasmas

open access: yes, 2004
While ion heating by elastic electron-ion collisions may be neglected for a description of the evolution of freely expanding ultracold neutral plasmas, the situation is different in scenarios where the ions are laser-cooled during the system evolution ...

Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

open access: yesMolecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

Tuning the conductivity of vanadium dioxide films on silicon by swift heavy ion irradiation

open access: yesAIP Advances, 2011
We demonstrate the generation of a persistent conductivity increase in vanadium dioxide thin films grown on single crystal silicon by irradiation with 1 GeV 238U swift heavy ions at room temperature.

Modulational Stability Analysis of Ion Temperature Gradient Modein Electron-ion Plasma

open access: yesKuwait Journal of Science, 2023
A theoretical investigation of the modulational stability of the ion temperature gradient (ITG) mode in electron–ion plasma is presented. The technique of reduction perturbation (RPT) is applied to the basic magneto hydrodynamic equations of ITG mode ...

Stabilized Radiation Pressure Dominated Ion Acceleration from Thin-foil Targets

open access: yes, 2010
We study transverse and longitudinal electron heating effects on the target stability and the ion spectra in the radiation pressure dominated regime of ion acceleration by means of multi dimensional particle-in-cell (PIC) simulations.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

open access: yesMolecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Single residues in the outer pore of TRPV1 and TRPV3 have temperature-dependent conformations. [PDF]

open access: yesPLoS ONE, 2013
Thermosensation is mediated by ion channels that are highly temperature-sensitive. Several members of the family of transient receptor potential (TRP) ion channels are activated by cold or hot temperatures and have been shown to function as temperature ...

Mean sheared flow and parallel ion motion effects on zonal flow generation in ion-temperature-gradient mode turbulence

open access: yes, 2009
The present work investigates the direct interaction of sheared mean flow with zonal flows (ZF) and the effect of parallel ion motion on ZF generation in ion-temperature-gradient (ITG) background turbulence. An analytical model for the direct interaction
