Low frequency electromagnetic radiation coming from gravitational waves generated by neutron stars [PDF]

open access: yes, 2017
We investigate the possibility of observing very low frequency (VLF) electromagnetic radiation produced from the vacuum by gravitational waves. We review the calculations leading to the possibility of vacuum conversion of gravitational waves into ...

A method for separating O-wave and X-wave and its application in digital ionosonde

open access: yesAnnals of Geophysics, 2014
Separation for O wave and X wave is a very important job in interpretation of ionograms, which is premise for automatic scaling. In this paper, a new digital method for separating O wave and X wave is presented, based on a numerical synthesizing ...

On the Phenomenology of Tachyon Radiation [PDF]

open access: yes, 1995
We present a brief overview of the different kinds of electromagnetic radiations expected to come from (or to be induced by) space-like sources (tachyons).

Vibration Error Analysis and Motion Compensation of Video Synthetic Aperture Radar

open access: yesLeida xuebao, 2015
Video Synthetic Aperture Radar (ViSAR) system offers high imaging frame rate, and high resolution, and it is consequently used to investigate and locate near-moving targets. Compared with microwave SAR, the practical application of ViSAR is restricted by

A Novel Strategy for Improving the Aeromagnetic Compensation Performance of Helicopters

open access: yesSensors, 2018
An aeromagnetic survey is an important method in magnetic anomaly detection and geophysical prospecting. The magnetic field is typically measured by optically pumped magnetometers (OPM) installed on the aircraft.

An Efficient Spectrum Reconstruction Algorithm for Non-Uniformly Sampled Signals and Its Application in Terahertz SAR

open access: yesRemote Sensing, 2023
An efficient spectrum reconstruction algorithm based on the Tikhonov regularization for terahertz (THz) synthetic aperture radar (SAR) azimuth non-uniform sampling is proposed in this article.

Multi-quasi-parabolic ionosphere model with EF-valley

open access: yesAnnals of Geophysics, 2016
We improve the conventional multi-quasi-parabolic (MQP) model and develop two MQP models with EF-valley by applying the predicted EF-valley parameter of the newest version of the International Reference Ionosphere.

Identifying the development in phase and amplitude of dipole and multipole radiation [PDF]

open access: yes, 2012
The spatial variation in phase and the propagating wave-front of plane wave electromagnetic radiation are widely familiar text-book territory. In contrast, the developing amplitude and phase of radiation emitted by a dipole or multipole source generally ...

miR-3614–5p downregulation promotes cadmium-induced breast cancer cell proliferation and metastasis by targeting TXNRD1

open access: yesEcotoxicology and Environmental Safety, 2022
Cadmium (Cd), which is considered an endocrine disruptor, has been linked to the onset of breast cancer (BC). Our recent study demonstrated that Cd-induced BC progression has a strong correlation with miR-374c-5p dysregulation. The aim of our work was to
