 2020-03-2611:25 [FZJ-2020-01610] Preprint et al Study of Three-Nucleon Dynamics in the dp Breakup Collisions using the WASA Detector Differential cross section for the 1H(d,pp)n breakup reaction at deuteron beam energy of 340 MeV has been measured with the use of WASA detector at COSY-Juelich. The set of proton-proton coincidences registered at Forward Detector has been analysed on dense grid of kinematic variables, giving in total around 5600 data points. [...] OpenAccess: PDF PDF (PDFA); 2020-03-1714:06 [FZJ-2020-01521] Preprint et al Technical Design Report for the PANDA Endcap Disc DIRC PANDA (anti-Proton ANnihiliation at DArmstadt) is planned to be one of the four main experiments at the future international accelerator complex FAIR (Facility for Antiproton and Ion Research) in Darmstadt, Germany. It is going to address fundamental questions of hadron physics and quantum chromodynamics using cooled antiproton beams with a high intensity and and momenta between 1.5 and 15 GeV/c.

A thorough understanding of the individual components, such as the ion conducting membrane and the electrode layers, can be obtained with scattering techniques on atomit to molecular length scales. [...] OpenAccess: PDF PDF (PDFA); 2020-02-2616:27 [FZJ-2020-01271] Preprint et al Worldwide Hydrogen Provision Scheme Based on Renewable Energy 2020-02-1409:51 [FZJ-2020-01077] Preprint Rossetti, G. Modeling the allosteric modulation on a G-Protein Coupled Receptor: the case of M2 muscarinic Acetylcholine Receptor in complex with LY211960 Scientific reports (2020) Allosteric modulation is involved in a plethora of diverse protein functions, which are fundamental for cells’ life. This phenomenon can be thought as communication between two topographically distinct site of a protein structure. [...] Restricted: DOCX; 2020-02-0708:13 [FZJ-2020-00940] Preprint et al Implementation of GENFIT2 as an experiment independent track-fitting framework The GENFIT toolkit, initially developed at the Technische Universitaet Muenchen, has been extended and modified to be more general and user-friendly. The new GENFIT, called GENFIT2, provides track representation, track-fitting algorithms and graphic visualization of tracks and detectors, and it can be used for any experiment that determines parameters of charged particle trajectories from spacial coordinate measurements. [...] OpenAccess: PDF PDF (PDFA); 2020-02-0611:59 [FZJ-2020-00925] Preprint Barnett, L. Sampling distribution for single-regression Granger causality estimators We show for the first time that, under the null hypothesis of vanishing Granger causality, the single-regression Granger-Geweke estimator converges to a generalised $\chi^2$ distribution, which may be well approximated by a $\Gamma$ distribution. We show that this holds too for Geweke's spectral causality averaged over a given frequency band, and derive explicit expressions for the generalised $\chi^2$ and $\Gamma$-approximation parameters in both cases. [...] OpenAccess: PDF PDF (PDFA); 2020-02-0514:37 [FZJ-2020-00896] Preprint et al CPlantBox, a whole plant modelling framework for the simulation of water and carbon related processes The interaction between carbon and flows within the plant is at the center of most growth and developmental processes. Understanding how these fluxes influence each other, and how they respond to heterogeneous environmental conditions, is important to answer diverse questions in forest, agriculture and environmental sciences. [...] OpenAccess: PDF; 2020-02-0514:35 [FZJ-2020-00895] Preprint et al Call for participation: Collaborative benchmarking of functional-structural root architecture models. The case of root water uptake Three-dimensional models of root growth, architecture and function are becoming important tools that aid the design of agricultural management schemes and the selection of beneficial root traits. However, while benchmarking is common in many disciplines that use numerical models such as natural and engineering sciences, functional-structural root architecture models have never been systematically compared. [...] OpenAccess: PDF PDF (PDFA); 2020-02-0514:34 [FZJ-2020-00894] Preprint et al Water and phosphorus uptake by upland rice root systems unraveled under multiple scenarios: linking a 3D soil-root model and data Background and aims Upland rice is often grown where water and phosphorus (P) are limited and these two factors interact on P bioavailability. To better understand this interaction, mechanistic models representing small-scale nutrient gradients and water dynamics in the rhizosphere of full-grown root systems are needed.Methods Rice was grown in large columns using a P-deficient soil at three different P supplies in the topsoil (deficient, suboptimal, non-limiting) in combination with two water regimes (field capacity versus drying periods).
