Continuous solutions of cosmic-rays and waves in astrophysical environments [PDF]

open access: yesScientific Reports, 2023
The propagation of energetic charged particles and cosmic rays in magnetized thermal plasma is focused. We consider a four-fluid system that consists of thermal plasma, cosmic rays, and two opposite propagating Alfvén waves to investigate the dynamics ...

Examination of Xmax anisotropy for the next generation Ultra-high energy cosmic rays observations [PDF]

open access: yesEPJ Web of Conferences, 2023
The estimation of mass composition ultra-high energy cosmic rays is essential to understand their origin and generation mechanism. Recent experiments are expected to discover anisotropy of mass composition in ultra-high energy cosmic rays.

Development of a Machine Learning Forecast Model for Global Horizontal Irradiation Adapted to Tibet Based on Visible All-Sky Imaging

open access: yesRemote Sensing, 2023
The Qinghai-Tibet Plateau is rich in renewable solar energy resources. Under the background of China’s “dual-carbon” strategy, it is of great significance to develop a global horizontal irradiation (GHI) prediction model suitable for Tibet.

RETRACTED: EEG Signal Connectivity for Characterizing Interictal Activity in Patients With Mesial Temporal Lobe Epilepsy

open access: yesFrontiers in Neurology, 2021
Over the last decade, several methods for analysis of epileptiform signals in electroencephalography (EEG) have been proposed. These methods mainly use EEG signal features in either the time or the frequency domain to separate regular, interictal, and ...

Texture-based brain networks for characterization of healthy subjects from MRI

open access: yesScientific Reports, 2023
Brain networks have been widely used to study the relationships between brain regions based on their dynamics using, e.g. fMRI or EEG, and to characterize their real physical connections using DTI.

Red Dwarfs as Sources of Cosmic Rays [PDF]

open access: yesEPJ Web of Conferences, 2022
The Pamela, Fermi, AMS-02 spectrometer experimental data cannot be explained using the diffusive models of propagation of cosmic-rays accelerated at the supernova shocks and require the existence of nearby sources of cosmic rays at the distances less ...

Charmed Galaxies [PDF]

open access: yesEPJ Web of Conferences, 2023
The quest for finding the origins of cosmic rays has been going on for many decades. Cosmic rays as charged particles react to cosmic magnetic fields and typically travel in diffusive motion through the Universe.

Observation of the Energy Dependence of Primary and Secondary Cosmic Rays with the AMS Detector on the International Space Station [PDF]

open access: yesEPJ Web of Conferences, 2019
Precision study of cosmic nuclei provides detailed knowledge on the origin and propagation of cosmic rays. AMS is a multi-purpose high energy particle detector designed to measure and identify cosmic ray nuclei with unprecedented precision. It is able to

Functionalized UiO-66-NH2 by trimellitic acid for highly selective adsorption of basic blue 3 from aqueous solutions

open access: yesFrontiers in Chemistry, 2022
A novel metal-organic framework (MOF) UiO-66-TLA (UiO-66-Trimellitic Acid) was synthesized by one-pot method with trimellitic acid as modifier, which can effectively remove the basic dye Basic Blue 3 (BB3) in wastewater. Modification with carboxyl groups

Large-scale cosmic ray fluctuations inferred from the ground-based neutron and ionizing component observations and their relevance to cosmic ray anisotropy

open access: yesGeofísica Internacional, 1988
Se estudia el comportamiento del espectro de potencia de las fluctuaciones en la intensidad de los rayos cósmicos para frecuencias menores de 10-4Hz, determinado a partir de las observaciones en superficie de las componentes nucleónica y de ionización ...
