Wave-Particle Interaction in the Ionosphere and magnetosphere
Antarctic Record, 1979 Wave-particle interactions that are important processes for the control of the electromagnetic states in the earth's magnetosphere are surveyed relatingto the auroral zone that is the most suitable window to clarify the various aspects of wave-particle ...

A review of frequency chirping mechanism of chorus waves in the Earth's magnetosphere
地球与行星物理论评, 2022 Whistler mode chorus waves are common and intense electromagnetic waves in the Earth's magnetosphere. They play a crucial role in magnetospheric electron dynamics by accelerating and scattering electrons over a wide energy range.

Conditional wave theory of environmental interactions with a quantum particle
Physical Review Research, 2020 We present an alternative formulation of quantum decoherence theory using conditional wave theory (CWT), which was originally developed in molecular physics (also known as exact factorization methods). We formulate a CWT of a classic model of collisional

Two types of ELF hiss observed at Varanasi, India [PDF]
Annales Geophysicae, 1999 The morphology of ELF hiss events observed at low-latitude ground station Varanasi (L = 1.07, geomagnetic latitude 14°55'N) are reported, which consist of two types: (1) events which propagated in ducted mode along the geomagnetic field line ...

Using MEPED observations to infer plasma density and chorus intensity in the radiation belts
Frontiers in Astronomy and Space Sciences, 2022 Efforts to model and predict energetic electron fluxes in the radiation belts are highly sensitive to local wave-particle interactions. In this study, we use multi-point measurements of precipitating and trapped electron fluxes to investigate the dynamic

Article: Heating of beam ions by ion acoustic waves [PDF]
Annales Geophysicae, 1998 Satellite measurements show that ion beams above the auroral acceleration region are heated to hundreds of eV in a direction perpendicular to the magnetic field. We show that ion acoustic waves may be responsible for much of this heating.

Landau Damping of Langmuir Waves: An Alternative Derivation
Physics, 2021 In this paper, a discussion of the Landau damping of Langmuir waves is presented together with a simple derivation which does not require the application of methods of complex analysis.

Wave–particle interactions in tokamaks
Nuclear FusionTransport consequences of the wave–particle interactions in the quasilinear plateau (QP) regime are presented. Eulerian approach is adopted to solve the drift kinetic equation that includes the physics of the nonlinear trapping (NT) and QP regimes.

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Molecular Oncology, EarlyView.Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...
