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.

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.

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). [...] OpenAccess: PDF PDF (PDFA); 2020-02-0414:57 [FZJ-2020-00864] Preprint et al Neuronal Causes and Behavioural Effects: a Review on Logical, Methodological, and Technical Issues With Respect to Causal Explanations of Behaviour in Neuroscience Elucidating causal, neurobiological underpinnings of behaviour is an ultimate goal of every neuroscientific study. However, due to the complexity of the brain as well as the complexity of the human environment, finding a~causal architecture that underlies behaviour remains a~formidable challenge. [...] OpenAccess: PDF PDF (PDFA); 2020-01-2909:43 [FZJ-2020-00651] Preprint et al Constraints on Flavor-Diagonal Non-Standard Neutrino Interactions from Borexino Phase-II The Borexino detector measures solar neutrino fluxes via neutrino-electron elastic scattering. Observed spectra are determined by the solar-$\nu_{e}$ survival probability $P_{ee}(E)$, and the chiral couplings of the neutrino and electron. [...] OpenAccess: PDF PDF (PDFA); External link: Fulltext 2020-01-2909:36 [FZJ-2020-00648] Preprint et al Search for low-energy neutrinos from astrophysical sources with Borexino We report on searches for neutrinos and antineutrinos from astrophysical sources performed with the Borexino detector at the Laboratori Nazionali del Gran Sasso in Italy. Electron antineutrinos (ν¯e) are detected in an organic liquid scintillator through the inverse β-decay reaction. [...] OpenAccess: PDF PDF (PDFA);
