Plasma-wave generation in a dynamic spacetime [PDF]

open access: yes, 2016
We propose a new electromagnetic-emission mechanism in magnetized, force-free plasma, which is driven by the evolution of the underlying dynamic spacetime.

Disks Surviving the Radiation Pressure of Radio Pulsars [PDF]

open access: yes, 2004
The radiation pressure of a radio pulsar does not necessarily disrupt a surrounding disk. The position of the inner radius of a thin disk around a neutron star can be estimated by comparing the electromagnetic energy density generated by the neutron star

1800 MHz Radiofrequency Electromagnetic Field Impairs Neurite Outgrowth Through Inhibiting EPHA5 Signaling

open access: yesFrontiers in Cell and Developmental Biology, 2021
The increasing intensity of environmental radiofrequency electromagnetic fields (RF-EMF) has increased public concern about its health effects. Of particular concern are the influences of RF-EMF exposure on the development of the brain. The mechanisms of

On classical description of radiation from neutral fermion with anomalous magnetic moment [PDF]

open access: yes, 2000
Electromagnetic radiation from an uncharged spin 1/2 particle with an anomalous magnetic moment moving in the classical electromagnetic external field originates from quantum spin-flip transitions.

Design of Wireless Automatic Synchronization for the Low-Frequency Coded Ground Penetrating Radar

open access: yesJournal of Electrical and Computer Engineering, 2015
Low-frequency coded ground penetrating radar (GPR) with a pair of wire dipole antennas has some advantages for deep detection. Due to the large distance between the two antennas, the synchronization design is a major challenge of implementing the GPR ...

Fluoride exposure induces lysosomal dysfunction unveiled by an integrated transcriptomic and metabolomic study in bone marrow mesenchymal stem cells

open access: yesEcotoxicology and Environmental Safety, 2022
Fluoride has received much attention for its predominant bone toxicity in the human body. However, the toxic mechanism of bone injury caused by fluoride exposure remains largely unclear. Bone marrow mesenchymal stem cells (BMSCs) are widely used as model

Quantum Theory of Self-Induced Transparency [PDF]

open access: yes, 1995
It is known that classical electromagnetic radiation at a frequency in resonance with energy splittings of atoms in a dielectric medium can be described using the classical sine-Gordon equation.

A Modified Magnetic Gradient Contraction Based Method for Ferromagnetic Target Localization

open access: yesSensors, 2016
The Scalar Triangulation and Ranging (STAR) method, which is based upon the unique properties of magnetic gradient contraction, is a high real-time ferromagnetic target localization method. Only one measurement point is required in the STAR method and it
