The Incidence of Retained Objects in Intraoperative X-rays for Missing Counts in Plastic Surgery: We Should Do Better

open access: yesPlastic and Reconstructive Surgery, Global Open, 2023
Background:. In the event of incorrect surgical counts, obtaining X-rays to rule out retained surgical items (RSI) is standard practice. However, these safeguards also carry risk.

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

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 from Hot Subdwarfs [PDF]

open access: yes, 2015
Thanks to the high sensitivity of the instruments on board the XMM-Newton and Chandra satellites, it has become possible to explore the properties of the X-ray emission from hot subdwarfs.

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

Reionization by Hard Photons: I. X-rays from the First Star Clusters [PDF]

open access: yes, 2001
Observations of the Ly-alpha forest at z~3 reveal an average metallicity Z~0.01 Z_solar. The high-redshift supernovae that polluted the IGM also accelerated relativistic electrons.

Internet hand x-rays: A comparison of joint space narrowing and erosion scores (Sharp/Genant) of plain versus digitized x-rays in rheumatoid arthritis patients

open access: yesBMC Musculoskeletal Disorders, 2002
Background The objective of the study is to examine the reliability of erosion and joint space narrowing scores derived from hand x-rays posted on the Internet compared to scores derived from original plain x-rays.

X-ray-Induced Heating in the Vicinity of the X-ray Interaction Point

open access: yesApplied Sciences, 2023
When X-rays pass through a material, radiation damage occurs, and heat is generated at the X-ray interaction point, which can then be transferred around the X-ray irradiation site. This X-ray-induced heat transfer can affect the temperature of the sample

Single shot diffraction of picosecond 8.7-keV x-ray pulses

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2012
We demonstrate multiphoton, single shot diffraction images of x rays produced by inverse Compton scattering a high-power CO_{2} laser from a relativistic electron beam, creating a pulse of 8.7 keV x rays.
