    Publicado 2019
    “…Discrepancies observed during the optics measurements at the Large Hadron Collider (LHC) and the Proton Synchrotron Booster (PSB) between different $\beta$-reconstruction approaches, show that the impact of the BPM calibration factors on the optics functions was higher than expected from the design values and tolerances. …”

    “…Successively presented are a study on attenuation length measurements of scintillating fibres, the development of a detector control system, a performance study of services, usage of a detector control system during physics data taking and the corresponding analysis of elastic scattered protons. The Scintillating Fibre (SciFi) tracker is part of the Upgrade I of the LHCb detector that is currently carried out during the second Long Shutdown period of the Large Hadron Collider (LHC). …”

    “…From 2026, the CERN Large Hadron Collider (LHC) will enter the High Luminosity phase, also known as phase-2, where the machine will almost double the number of proton collisions per second. This luminosity increase brings challenges to the LHC experiments, like CMS, particularly to their most forward detector sub-systems closer to the beamline. …”

    “…In the presumptive common mechanism, the phosphoprotein’s seryl/threonyl phosphate coordinates the M(1)/M(2) system, W(1)(OH(−)) attacks the central P atom, rupturing the antipodal bond, and simultaneously, a histidine/aspartate tandem protonates the exiting seryl/threonyl alkoxide. Based on studies of PPP5C, a conserved arginine proximal to M(1) is also expected to bind the substrate’s phosphate group in a bidentate fashion. …”

    “…This has a decisive effect on the interfacial processes that can occur since NP–water interactions can be uniquely investigated as a function of pH and provides an environment allowing for unhindered proton migration. Our studies confirm that water is dissociatively adsorbed at the hematite surface and molecularly adsorbed at the TiO(2) NP surface at low pH. …”

    “…Biochemical workup was remarkable for elevated CgA of 4800 ng/mL (n: <311 ng/mL) and elevated gastrin level of 700 pg/mL (n: <100 pg/mL); however, the patient was on proton pump inhibitors. A Ga-68 DOTATATE scan revealed 4 DOTATATE avid masses in the pancreatic head, neck, body and tail, the largest measuring 2.3 cm in the pancreatic head. …”
