C++ Declarative API – Implementation Overview Within the XRootD Framework / Poenaru, Robert (Bucharest, IFIN-HH) ; Simon, Michal (CERN)
A brief description of the XRootD architecture and its purpose within the Worldwide Large Hadron Collider Computing Grid (WLCG), alongside an overview of the server-and client- sides of the XRootD framework are discussed in the present work. The client-side of XRootD has a relatively new feature called Declarative API. [...]

The CLAS12 Geant4 simulation / Ungaro, M (Jefferson Lab) ; Angelini, G (George Washington U.) ; Battaglieri, M (INFN, Genoa) ; Burkert, V D (Jefferson Lab) ; Carman, D S (Jefferson Lab) ; Chatagnon, P (Orsay, IAS) ; Contalbrigo, M (INFM, Ferrara) ; Defurne, M (IRFU, Saclay) ; De Vita, R (INFN, Genoa) ; Duran, B (Temple U.) et al.
The Geant4 Monte-Carlo (GEMC) package is used to simulate the passage of particles through the various CLAS12 detectors. The geometry is implemented through a database of Geant4 volumes created either through the GEMC native API, by the CLAS12 geometry service, or imported from the CAD engineering model. [...]
