We report the experimental demonstration of efficient interaction multi-kilo-electron-volt heralded x-ray photons with a beam splitter. The measured photon rate at outputs splitter is about $0.01\text{ }\text{ }\mathrm{counts}/\mathrm{s}$ which comparable to in absence use this together number and energy resolving detectors show directly that when single interacts it can only be detected either...

We herewith present a novel approach to predict protein-ligand binding modes from the single two-dimensional structure of the ligand. Known protein-ligand X-ray structures were converted into binary bit strings encoding protein-ligand interactions. An artificial neural network was then set up to first learn and then predict protein-ligand interaction fingerprints from simple ligand descriptors....

Context. In the framework of the study of the X-ray and optical emission in supernova remnants we focus on an isolated X-ray knot in the northern rim of the Vela SNR (Vela FilD), whose X-ray emission has been studied and discussed in Paper I. Aims. We aim at understanding the physical origin of the X-ray and optical emission in FilD, at understanding the role of the different physical processes...

It is shown that an instanton induced interaction between quarks produces a very deeply bound H-dibaryon with mass below 2M N , M H = 1718 MeV. Therefore the H-dibaryon is predicted to be a stable particle. The reaction of photodisintegration of H-dibaryon to 2Λ in during of its penetration into cosmic microwave background will result in a new possible cutoff in the cosmic-ray spectrum. This pr...
