/ Sanjari, M S (Darmstadt, GSI) ; Dmytriiev, D (Darmstadt, GSI ; U. Heidelberg (main)) ; Litvinov, Yu A (Darmstadt, GSI ; U. Heidelberg (main)) ; Gumenyuk, O (CERN ; Darmstadt, GSI) ; Hess, R (Darmstadt, GSI) ; Joseph, R (Darmstadt, GSI) ; Litvinov, S A (Darmstadt, GSI) ; Steck, M (Darmstadt, GSI) ; Stöhlker, Th (Darmstadt, GSI)
An improved design of a longitudinally sensitive resonant Schottky cavity pickup for the heavy ion storage rings of the Facility for Antiproton and Ion Research in Europe (FAIR) project is reported. The new detector has a higher measured Q value of ∼3000 and a higher simulated shunt impedance of 473.3 kΩ. [...]

BioDynaMo: a modular platform for high-performance agent-based simulation
/ Breitwieser, Lukas (CERN ; Zurich, ETH) ; Hesam, Ahmad (CERN ; Zurich, ETH) ; de Montigny, Jean (CERN) ; Vavourakis, Vasileios (Cyprus U. ; University Coll. London) ; Iosif, Alexandros (Cyprus U.) ; Jennings, Jack (Newcastle upon Tyne U.) ; Kaiser, Marcus (Newcastle upon Tyne U. ; Shanghai SSRF ; Nottingham U.) ; Manca, Marco (Unlisted, NL) ; Di Meglio, Alberto (CERN) ; Al-Ars, Zaid (Delft Tech. U.) et al.
Motivation: Agent-based modeling is an indispensable tool for studying complex biological systems. However,
existing simulation platforms do not always take full advantage of modern hardware and often have a field-specific
software design.
Results: We present a novel simulation platform called BioDynaMo that alleviates both of these problems.
BioDynaMo features a modular and high-performance simulation engine. [...]

Neopterin formation through radical scavenging of superoxide by the macrophage synthesised antioxidant 7,8-dihydroneopterin
/ Baxter-Parker, Gregory (Canterbury U.) ; Prebble, Hannah M (Canterbury U.) ; Cross, Sean (Canterbury U.) ; Steyn, Nina (Canterbury U.) ; Shchepetkina, Anastasia (Canterbury U.) ; Hock, Barry D (Otago U.) ; Cousins, Andrew (Unlisted, NZ) ; Gieseg, Steven P (CERN)
Clinical measurement of neopterin has been extensively used as a marker of inflammation but the in vivo mechanism generating neopterin is poorly understood. Neopterin is described as the oxidation product of 7,8-dihydroneopterin, a potent antioxidant generated by monocyte/macrophages in response to interferon-γ. [...]

Measurements of the $^{33}$S$ ($n$, α)$^{30}$ $Si$ cross-section at n_TOF and ILL: Implications in neutron capture therapy
/ Praena, Javier (Granada U.) ; Isabelópez-Casas, L (Granada U.) ; Sabat, Mariaé-Gilarte (CERN ; Seville U.) ; Arias, Fernando de Saavedra (Granada U.) ; Porras, Ignacio (Granada U.)
Up to a couple of years ago, the 33S(n, α)30Si cross-section data had been limited and scarce. The origin in the solar system of 36S had been the only motivation to study that cross-section. [...]

Secondary electron generation mechanisms in carbon allotropes at low impact electron energies
/ Bellissimo, Alessandra (Rome U. ; CERN) ; Pierantozzi, Gian Marco (Rome U.) ; Ruocco, Alessandro (Rome U.) ; Stefani, Giovanni (Rome U.) ; Ridzel, Olga Yu (TU Vienna) ; Astašauskas, Vytautas (TU Vienna) ; Werner, Wolfgang S M (TU Vienna) ; Taborelli, Mauro (CERN)
More than a century after the discovery of the electron, there are still fundamental, yet unresolved, questions
concerning the generation-ejection mechanism of the ubiquitous Secondary Electrons (SEs) from a solid surface.
Broadness of the field of application for these SEs makes it desirable to be able to control this phenomenon,
which requires the understanding of the elementary physical mechanism leading to their generation and
emission. This paper reports on the dissection of such a tangled process operated by the help of spectroscopic
tools of increasing finesse; measuring differential cross sections with an increasing degree of differentiation.
These results demonstrate that single ionising scattering events, assisted by collective excitations, constitute the
fundamental ingredient leading to SE-generation and -emission. [...]
