[{"status":"public","date_updated":"2024-01-09T09:02:22Z","abstract":[{"text":"Several fixed-target experiments reported J/ψ and ϒ polarizations, as functions of Feynman x (xF) and transverse momentum (PT), in three different frames, using different combinations of beam particles, target nuclei, and collision energies. Despite the diverse and heterogeneous picture formed by these measurements, a detailed look allows us to discern qualitative physical patterns that inspire a simple empirical model. This data-driven scenario offers a good quantitative description of the J/ψ and ϒ(1S) polarizations measured in proton- and pion-nucleus collisions, in the xF 0.5 domain: more than 80 data points (not statistically independent) are well reproduced with only one free parameter. This study sets the context for future low-PT\r\n quarkonium polarization measurements in proton- and pion-nucleus collisions, such as those to be made by the AMBER experiment, and shows that such measurements provide significant constraints on the poorly-known parton distribution functions of the pion.","lang":"eng"}],"oa_version":"Published Version","publication_status":"published","day":"10","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"has_accepted_license":"1","scopus_import":"1","citation":{"chicago":"Faccioli, Pietro, Ilse Krätschmer, and Carlos Lourenço. “Low-PT Quarkonium Polarization Measurements: Challenges and Opportunities.” <i>Physics Letters B</i>.

Here we provide first steps towards the extension of this stochastic approach to bosonic systems by considering the one-dimensional quantum quartic oscillator. We show how to exactly parameterize the time evolution of this prototypical model via the dynamics of a set of classical variables. We interpret these variables as stochastic processes, which allows us to propose a novel way to numerically simulate the time evolution of the system.

Here we combine protein deuteration, fast magic-angle spinning (~45–60 kHz) and proton detection to study dynamics of ubiquitin in microcrystals, and in particular a mutant in a region that undergoes microsecond motions in a β-turn region in the wild-type protein. We use 15N R1ρ relaxation measurements as a function of the radio-frequency (RF) field strength, i.e. relaxation dispersion, to probe how the G53A mutation alters these dynamics. We report a population-inversion of conformational states: the conformation that in the wild-type protein is populated only sparsely becomes the predominant state. We furthermore explore the potential to use amide-1H R1ρ relaxation to obtain insight into dynamics. We show that while quantitative interpretation of 1H relaxation remains beyond reach under the experimental conditions, due to coherent contributions to decay, one may extract qualitative information about flexibility.","lang":"eng"}],"author":[{"full_name":"Gauto, Diego F.","first_name":"Diego F.","last_name":"Gauto"},{"first_name":"Audrey","full_name":"Hessel, Audrey","last_name":"Hessel"},{"last_name":"Rovó","first_name":"Petra","full_name":"Rovó, Petra"},{"last_name":"Kurauskas","full_name":"Kurauskas, Vilius","first_name":"Vilius"},{"last_name":"Linser","full_name":"Linser, Rasmus","first_name":"Rasmus"},{"full_name":"Schanda, Paul","first_name":"Paul","orcid":"0000-0002-9350-7606","last_name":"Schanda","id":"7B541462-FAF6-11E9-A490-E8DFE5697425"}],"_id":"8447"},{"author":[{"last_name":"Franco","first_name":"Rémi","full_name":"Franco, Rémi"},{"last_name":"Favier","full_name":"Favier, Adrien","first_name":"Adrien"},{"full_name":"Schanda, Paul","first_name":"Paul","id":"7B541462-FAF6-11E9-A490-E8DFE5697425","last_name":"Schanda","orcid":"0000-0002-9350-7606"},{"first_name":"Bernhard","full_name":"Brutscher, Bernhard","last_name":"Brutscher"}],"_id":"8448","day":"01","date_published":"2017-08-01T00:00:00Z","page":"125-129","oa_version":"None","publication_status":"published","abstract":[{"lang":"eng","text":"We present an improved fast mixing device based on the rapid mixing of two solutions inside the NMR probe, as originally proposed by Hore and coworkers (J.

The novelty of this device is that it allows removing the injector from the NMR detection volume after mixing, and thus provides good magnetic field homogeneity independently of the initial sample volume placed in the NMR probe. The apparatus is simple to build, inexpensive, and can be used without any hardware modification on any type of liquid-state NMR spectrometer. We demonstrate the performance of our fast mixing device in terms of improved magnetic field homogeneity, and show an application to the study of protein folding and the structural characterization of transiently populated folding intermediates."}],"doi":"10.1016/j.jmr.2017.05.016","language":[{"iso":"eng"}],"year":"2017","publisher":"Elsevier","date_updated":"2021-01-12T08:19:20Z","status":"public","type":"journal_article","month":"08","publication_identifier":{"issn":["1090-7807"]},"quality_controlled":"1","publication":"Journal of Magnetic Resonance","title":"Optimized fast mixing device for real-time NMR applications","volume":281,"article_type":"original","date_created":"2020-09-18T10:06:27Z","citation":{"ama":"Franco R, Favier A, Schanda P, Brutscher B.

Averaging of the dipolar coupling reports on motions on time scales up to the inverse of the coupling constant, in our case tens of microseconds. Combining dipolar-coupling derived order parameters that characterize the amplitudes of the motion with relaxation data leads to a more precise characterization of the dynamical parameters and helps to disentangle the amplitudes and the time scales of the motional processes, which impact relaxation rates in a highly correlated way. Here. we describe and characterize an improved experimental protocol – based on REDOR – to measure these couplings in perdeuterated proteins with a reduced sensitivity to experimental missettings. Because such effects are presently the dominant source of systematic errors in experimental dipolar-coupling measurements, these compensated experiments should help to significantly improve the precision of such data.

To achieve the highest possible sensitivity, SOFAST-HMQC experiments are preferably performed on high-field NMR spectrometers equipped with cryogenically cooled probes. The duty cycle of over 80% in fast-pulsing SOFAST-HMQC experiments, however, may cause problems when using a cryogenic probe. Here we introduce SE-IPAP-SOFAST-HMQC, a new pulse sequence that provides comparable sensitivity to standard SOFAST-HMQC, while avoiding heteronuclear decoupling during 1H detection, and thus significantly reducing the radiofrequency load of the probe during the experiment. The experiment is also attractive for fast and sensitive measurement of heteronuclear one-bond spin coupling constants.","lang":"eng"}],"author":[{"first_name":"Thomas","full_name":"Kern, Thomas","last_name":"Kern"},{"id":"7B541462-FAF6-11E9-A490-E8DFE5697425","last_name":"Schanda","orcid":"0000-0002-9350-7606","full_name":"Schanda, Paul","first_name":"Paul"},{"last_name":"Brutscher","first_name":"Bernhard","full_name":"Brutscher, Bernhard"}],"_id":"8482"},{"article_processing_charge":"No","issue":"2","extern":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","keyword":["Nuclear and High Energy Physics","Biophysics","Biochemistry","Condensed Matter Physics"],"intvolume":"       178","date_created":"2020-09-18T10:13:51Z","citation":{"ieee":"P.
