Anticorrelation between Ion Acceleration and Nonlinear Coherent Structures from Laser-Underdense Plasma Interaction [PDF]
, 2011 In laser-plasma experiments, we observed that ion acceleration from the Coulomb explosion of the plasma channel bored by the laser, is prevented when multiple plasma instabilities such as filamentation and hosing, and nonlinear coherent structures ...

New Journal of Physics, 2021 By taking the spin and polarization of the electrons, positrons and photons into account in the strong-field QED processes of nonlinear Compton emission and pair production, we find that the growth rate of QED cascades in ultra-intense laser fields can ...

Electron density diagnostics in atmospheric pressure radio frequency dielectric barrier discharge and discharge with bare electrode [PDF]
, 2019 Electron densities in two types of atmospheric pressure radio frequency plasma sources: dielectric barrier discharge (DBD) and discharge with bare electrode (DBE) are investigated by analysis of Stark broadening of Hydrogen Balmer (Hβ) lines.

Microwave power coupling in a surface wave excited plasma
, 2014 In recent decades, different types of plasma sources have been used for various types of plasma processing, such as, etching and thin film deposition. The critical parameter for effective plasma processing is high plasma density. One type of high density

The close T Tauri binary system V4046 Sgr: Rotationally modulated X-ray emission from accretion shocks [PDF]
, 2011 We report initial results from a quasi-simultaneous X-ray/optical observing campaign targeting V4046 Sgr, a close, synchronous-rotating classical T Tauri star (CTTS) binary in which both components are actively accreting.

Variable X-ray emission from the accretion shock in the classical T Tauri star V2129 Ophiuchi [PDF]
, 2011 Context. The soft X-ray emission from high density plasma observed in several CTTS is usually associated with the accretion process. However, it is still unclear whether this high density “cool” plasma is heated in the accretion shock, or if it is ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Calibration of Swarm Plasma Densities Overestimation Using Neural Networks
Space WeatherRecent studies have shown that the measurements of Langmuir Probes (LPs) onboard ESA's Swarm mission overestimate ion densities on the nightside by up to 50%. The overestimation is due to the assumption of oxygen‐only plasma for ion density calculations,
