polyhydroxyalkanoates (phas) are naturally occurring polyester that can be accumulated in bacterial cells as a carbon and energy storage compound. they are metabolized by many microorganisms. these biopolymers accumulate in microbial cells under stress conditions such as limitation of nitrogen, phosphate, sulfur, oxygen, and excess carbon source. currently, phas have attracted increasing intere...

Micromagnetic beads are widely used in biomedical applications for cell separation, drug delivery, and hypothermia cancer treatment. Here we propose to use self-organized magnetic bead structures which accumulate on fixed magnetic seeding points to isolate circulating tumor cells. The analysis of circulating tumor cells is an emerging tool for cancer biology research and clinical cancer managem...

Magnetic detection technology has wide applications in the fields of geological exploration, biomedical treatment, wreck removal and localization of unexploded ordinance. A large number of methods have been developed to locate targets with static magnetic fields, however, the relation between the problem of localization of moving objectives with alternating magnetic fields and the localization ...

Turbulence with an associated turbulent magnetic field is common in astrophysical environments. The determination of the transport of charged particles both parallel and perpendicular to the mean magnetic field is of considerable interest. Quasi-linear analysis or direct numerical simulation can be used to find the effects of the turbulent magnetic field on the transport of charged particles. A...

An interface-tracking numerical algorithm for the simulation of magnetohydrodynamic multiphase / free surface flows in the low-magnetic-Reynolds-number approximation of (Samulyak R., Du J., Glimm J., Xu Z., J. Comp. Phys., 2007, 226, 1532) is described. The algorithm has been implemented in multi-physics code FronTier and used for the simulation of MHD processes in liquids and weakly ionized pl...

The magnetic field generation by a relativistic laser light irradiated on a thin target at the oblique incidence is investigated using a two dimensional particlein-cell simulation. The surface magnetic field inhibits the electron transport towards the inside plasma, when an incident angle exceeds the critical angle, which depends on the laser and plasma parameters.

OBJECTIVE The behavior of beta particles under the magnetic field was investigated both theoretically and experimentally based on the assumption of reducing the damage to the normal tissues created by using magnetic field in radionuclide therapy. METHODS A water-filled spherical medium and a beta particle source was formed by using Geant4 simulation software for the theoretical study. After a...

Abstract We present the simulation methodology and results of our new data-driven global coronal magnetohydrodynamics (MHD) model. In this model, solar-surface electric field is first calculated such that curl will satisfy both induction equation given temporal variations magnetic field. use synoptic maps Helioseismic Magnetic Imager three-component vector-magnetic-field data to specify magneti...

A Magneto Plasma Sail (MPS) produces a propulsive force by the interaction between the solar wind and an artificial magnetic field inflated by a plasma jet injection. Using a 2D hybrid PIC simulation code, the parametric study of magnetic inflation by the plasma jet injection is performed under different realistic parameters in terms of plasma material (Ar/Xe) and injection direction. We evalua...
