چکیده
This article presents current density profiles due to Lorentz and hydrodynamic forces in the presence of spatially varying plasma parameters, electrostatic field (E0→), microwave electric (E1→̃) obtained from experiments a confined by dipole magnet driven at steady state. The E0→ (or E1→̃) pressure tensor P0¯ P1¯) were determined obtain total J0→ J1→̃) various spatial locations employing electrical conductivity S¯DC S¯AC) as previous work [Nanda et al., Phys. Plasmas 29, 062105 (2022)]. results show that DC force dominates over those force, converse is observed case AC density. Furthermore, flow regulated bounce motion (along r̂ θ̂) grad-curvature drift ϕ̂), whereas E→×B→ controls along three directions, where r̂, θ̂, ϕ̂ represent unit vectors spherical polar co-ordinates. dominance θ̂ directs particles azimuthal direction J→×B→ force. prevents loss radial thus helping overall confinement. reveals interesting features profiles, guided motion, magnetic drifts, anisotropic tensor, which would be beneficial for understanding laboratory space plasmas.

fMRI-constrained dipole fits and current density reconstructions
1. Introduction Hemodynamic priors in the MEG/EEG inverse problem promise to raise spatial resolution, as fMRI maps have a resolution in the mm range [1]. On the other hand, MEG/EEG data could add information about the temporal dynamics of the underlying brain activity. To achieve a combination of these modalities, the results of an fMRI analysis shall be used as constraints in the subsequent E...
متن کاملComputational Lipidology: Predicting Lipoprotein Density Profiles in Human Blood Plasma
Monitoring cholesterol levels is strongly recommended to identify patients at risk for myocardial infarction. However, clinical markers beyond "bad" and "good" cholesterol are needed to precisely predict individual lipid disorders. Our work contributes to this aim by bringing together experiment and theory. We developed a novel computer-based model of the human plasma lipoprotein metabolism in ...
متن کاملStationary density profiles in the levitated dipole experiment: towards fusion without tritium fuel
The Levitated Dipole Experiment (LDX) is used to study hightemperature plasma confined by the magnetic field produced by a high-current superconducting ring. Multiple-frequency ECRH heats and sustains plasma discharges for long, quasi-steady periods, and conditions of high plasma beta are reached by adjusting the rate of neutral fueling. When the superconducting ring is levitated by attraction ...
متن کاملFour-dimensional ultrasound current source density imaging of a dipole field.
Ultrasound current source density imaging (UCSDI) potentially transforms conventional electrical mapping of excitable organs, such as the brain and heart. For this study, we demonstrate volume imaging of a time-varying current field by scanning a focused ultrasound beam and detecting the acoustoelectric (AE) interaction signal. A pair of electrodes produced an alternating current distribution i...
متن کاملVisualization of cardiac dipole using a current density map: detection of cardiac current undetectable by electrocardiography using magnetocardiography.
A close relationship exists between electric current and the magnetic field. However, electricity and magnetism have different physical characteristics, and magnetocardiography (MCG) may provide information on cardiac current that is difficult to obtain by electrocardiography (ECG). In the present study, we investigated the issue of whether the current density map method, in which cardiac curre...
