We present a novel scheme for dense electron acceleration driven by the laser irradiation of near-critical-density plasma. The reflux effect in transversely tailored plasma is particularly enhanced area peak density. observe bubble-like distribution re-injected electrons, which forms strong quasistatic electromagnetic field that can accelerate electrons longitudinally while also preserving tran...

A simple heuristic model is developed to examine the feasibility of using radiation pressure as a means to transport plasma dust out of the path of the forthcoming electron or photon beam. A slow electromagnetic surface wave coupled to a planar target or substrate exerts the required pressure in the removal process. The model is examined using data and parameters from single-shot radiography ex...

Hollow cathodes are important devices used for spacecraft electric propulsion. The hollow cathode has two operational modes. One mode is a stable called the spot mode, and other an unstable plume mode. Operation in should be avoided since instability causes high-energy ions that sputter-erode parts. In this study, relationship between discharge oscillations ion energy distribution was investiga...

background: there are varieties of purification techniques for separation of human plasma proteins such as salting out, ion exchange chromatography, and ethanol fractionation. there are limitations for each method, for example in salting out method, the salt has to be removed in an additional step. ion exchange chromatography is difficult for scaling up, and plasma fractionation is a time consu...

Plasma impedance probes (PIPs) are a type of RF probe that primarily measures electron density. This work introduces two advancements: streamlined analytical model for interpreting PIP-monopole measurements and techniques achieving ≥1 MHz time-resolved PIP measurements. The model’s improvements include introducing sheath thickness as measurement providing more accurate method measuring density ...

[1] Voyager 2 is making the first plasma measurements in the heliosheath. The radial flow speeds in the heliosheath vary between 80 and 200 km/s with an average speed of 138 km/s. The flow in the T (azimuthal) direction is fairly constant and averages about 48 km/s; the flow direction is consistent with flow away from the heliospheric nose. Flow in the N (meridional) direction is also away from...

Antineovascular therapy (ANET), which eradicates angiogenic endothelial cells by specifically delivered anticancer drugs to tumor cells to obtain complete cutoff of blood supply, is an effective modality for cancer treatment. Since the expression of vascular endothelial growth factor (VEGF) in hypoxic tumor cells is known to fluctuate in a circadian oscillation, we investigated the chronopharma...

Aims. We present an investigation into how the cooling of the background plasma influences the propagation of slow and fast MHD wave modes supported by an unbounded, homogenous plasma. Previous investigations have suggested that the cooling of the plasma and a reduction in density could lead to the damping of fast magneto-acoustic oscillations. We aim to investigate whether cooling of the backg...

Glycolytic oscillations, and in particular the synchronisation of these oscillations, have been intensively analysed experimentally as well as theoretically. Because the cellular membrane is permeable for products of glycolysis as acetaldehyde/pyruvate, cells can interact via exchanging these compounds. Various theoretical models have been proposed to explain the synchronisation of glycolytic o...

We describe aspects of particle creation in strong fields using a quantum kinetic equation with a relaxation-time approximation to the collision term. The strong electric background field is determined by solving Maxwell’s equation in tandem with the Vlasov equation. Plasma oscillations appear as a result of feedback between the background field and the field generated by the particles produced...
