The X-ray image of a patient with COVID-19 infection depicts hazy opacity and fuzziness near the lung region. The lung region of a healthy subject appears to be clear and sharp. Deep leaning methods have demonstrated great success in many computer vision tasks [3]. Research has been ...

When we asked our contributors what their most favorite dive location was, they came back with photos and stories of beautiful and exciting spots both near and far from home. From the tropical waters of Papua New Guinea, Indonesia, the Philippines, Chuuk, Mexico's Revillagigedo Islands, Solomo...
Novel X-ray methods are transforming the study of the functional dynamics of biomolecules. Key to this revolution is detection of often subtle conformational changes from diffraction data. Diffraction data contain patterns of bright spots known as reflec

Usually, the cleaning station will be close to an area with a strong current that brings the rich plankton which mantas feed on, which explains the early reports of mantas near Gona Bara Bara as close by as the China Strait that connects the Coral Sea to the south with Milne Bay and the...
LM –Linear Motor autofocus system is fast, near-silent, and highly responsive. Super EBC –Super Electron Beam Coating is a multi-layer lens coating that minimizes flare and ghosting. Fujinon Aspherical Lens –An aspherical lens directs the rays of light from all its points to a central poin...
PLP-bound hSHMT2 forms hexagonal, rod-shaped crystals, space group P6522, with long cell edges (>150 Å) that diffract X-rays to resolutions of 2.3–2.5 Å using synchrotron radiation at cryogenic temperatures18,37,62,63. Such hSHMT2 crystals are not amenable to neutron crystallo...
The attained highly intense X-rays, surpassing the previous intensity by a hundred-fold, induced the vigorous ionization of chromium, suggesting the creation of solid-density heavy bare atomic nuclei. Our results, which demonstrate the realization of stable ultraintense XFEL beams by forming de...
Worldwide, pneumonia is the leading cause of infant mortality. Experienced radiologists use chest X-rays to diagnose pneumonia and other respiratory diseases. The diagnostic procedure's complexity causes radiologists to disagree with the decision. Early
