Shallow Convolutional Neural Network for COVID-19 Outbreak Screening using Chest X-rays [PDF]

open access: yes, 2020
Among radiological imaging data, chest X-rays are of great use in observing COVID-19 mani- festations. For mass screening, using chest X-rays, a computationally efficient AI-driven tool is the must to detect COVID-19 positive cases from non-COVID ones ...

Ionization and heating by X-rays and cosmic rays*

open access: yesEPJ Web of Conferences, 2015
High-energy radiation from the central T Tauri and protostars plays an important role in shaping protoplanetary disks and influences their evolution. Such radiation, in particular X-rays and extreme-ultraviolet (EUV) radiation, is predominantly generated

X-ray emission characteristics in magnetically driven plasma jet experiments on PTS facility

open access: yesMatter and Radiation at Extremes, 2020
Jets are commonly observed astrophysical phenomena. To study the x-ray emission characteristics of jets, a series of radial foil Z-pinch experiments are carried out on the Primary Test Stand at the Institute of Fluid Physics, China Academy of Engineering

X-rays Stimulate Granular Secretions and Activate Protein Kinase C Signaling in Human Platelets

open access: yesCurrent Issues in Molecular Biology, 2023
X-rays can induce morphological as well as functional changes in cells. Platelets are anuclear cellular fragments originating from megakaryocytes and are the major regulators in hemostasis and thrombosis. Platelet products are irradiated to avoid medical

THE MAN BEHIND THE CURTAIN: X-RAYS DRIVE THE UV THROUGH NIR VARIABILITY IN THE 2013 ACTIVE GALACTIC NUCLEUS OUTBURST IN NGC 2617 [PDF]

open access: yes, 2013
After the All-Sky Automated Survey for SuperNovae discovered a significant brightening of the inner region of NGC 2617, we began a ∼70 day photometric and spectroscopic monitoring campaign from the X-ray through near-infrared (NIR) wavelengths. We report
