The solar system comprises a relatively small number of X‐ray emitting objects, which are associated with a variety of physical emission processes: we can explore them with good spatial and temporal precision at relatively local distances, and in situ as well, unlike the rest of the Universe....
News & Views31 Oct 2024Nature Photonics Volume: 18, P: 1129-1130 Nonlinear absorption of an X-ray pulse during the formation of warm dense matter A bright, ultrashort X-ray pulse is used to transiently create and characterize warm dense copper. As the pulse intensity is increased, the opac...

The normal chest X-ray (left panel) depicts clear lungs without any areas of abnormal opacification in the image. Bacterial pneumonia (middle) typically exhibits a focal lobar consolidation, in this case in the right upper lobe (white arrows), whereas viral pneumonia (right) manifests with a ...
NASA's Chandra X-ray Observatory has taken space-based images of the universe in X-ray light since 1999. See spectacular photos by the Chandra space telescope here.
X-Ray imaging is a technique that relies on the differential absorption of photons by tissues based on their electron density. It produces two-dimensional images of three-dimensional structures by detecting the photons passing through the body using film or digital detectors. ...
TorchXRayVision is an open source software library for working with chest X-ray datasets and deep learning models. It provides a common interface and common pre-processing chain for a wide set of publicly available chest X-ray datasets. In addition, a number of classification and representation ...
The utility model discloses an X-ray tube with various size focuses and two-member filaments. A filament is added on the basis of the single filament of the original size focuses to change the single into a set. The life of the filament is improved to one time. Consequently, the service...
David W L Hukins 1981 Oxford: Pergamon ix + 164 pp price £11.95Most books on x-ray diffraction relate to crystalline materials (where the solving of structures has become a rather mechanical process) and, because of the breadth of the subject, are either very superficial or indulge in con...
