Triple Coincidence Beam Spin Asymmetry Measurements in Deeply Virtual Compton Scattering
<p>The Generalized Parton Distributions (GPDs) provides hitherto the most complete information about the quark structure of hadron. GPDs are accessible through hard-exclusive reactions, among which Deeply Virtual Compton Scattering (DVCS) is the cleanest reaction. A dedicated DVCS experiment on …

Exclusive pi0 production at HERMES: detection - simulation - analysis
… framework of Generalized Parton Distributions (GPDs) provides access to the hitherto unknown quark orbital angular momentum. These GPDs can be probed via the measurement of so-called exclusive reactions. In these reactions the initial and final state are fully known. In the Hermes experiment …

Non convulsive status epilepticus: ηλεκτροεγκεφαλογραφικά πρότυπα και συσχέτιση με υποκείμενη παθολογία / Non convulsive status epilepticus: electroencephalography patterns and correlation with underlying pathology
… RDA (50%), τα generalized periodic discharges – GPDs (31,8%) και τα lateralized periodic discharges – LPDs (18,2%). Τα GPDs συσχετίστηκαν κυρίως με μεταβολικές ή τοξικές διαταραχές, ενώ τα LPDs εμφανίστηκαν συχνότερα σε ασθενείς με εστιακές δομικές αλλοιώσεις, όπως ισχαιμικές βλάβες ή …

UNRAVELING THE NUCLEON 3D STRUCTURE FROM EXPERIMENT, LATTICE, AND GLOBAL ANALYSIS
… hand, kinematical corrections from higher-twist GPDs eliminate the light-cone dependence at twist three. Those light-cone dependencies are studied systematically at JLab 12 GeV and future EIC kinematics. They serve as the intrinsic systematic uncertainties in extracting the Compton form factors. …

A Model of Motivational Spillover: When One Thing Leads to Another
… with positive affect such that negative GPDs resulted in low levels of positive affect and positive GPDs resulted in high levels of positive affect. This positive affect was in turn positively related to self-efficacy for the SPT. Self-efficacy was positively associated with personal …

Photodetectors for graphene-based integrated photonics
… show plasmonic enhanced graphene photodetectors (GPDs) on silicon nitride waveguides, which generate a voltage from optically generated hot-carrier distributions in SLG via the photo-thermoelectric (PTE) effect. Then, I demonstrate PTE-GPDs—fabricated from layered material heterostructures—on a …

Deeply Virtual Compton Scattering at Hall A, Jefferson Lab
… gaps of QCD. Generalized Parton Distributions (GPDs) provide simultaneous information of both spacial and longitudinal momentum distributions of constituents of a quark-gluon system. Deeply Virtual Compton Scattering (DVCS) is understood to be the simplest and cleanest process to access GPDs. …

Deeply Virtual Compton Scattering off unpolarised deuterium at HERMES
… process. These measurements are sensitive to GPDs, allowing further experimental constraints to be made on the components of nucleon spin. In the Winter shutdown period 2005-2006 HERMES was upgraded with a Recoil Detector in the target region. This allowed the experiment to make exclusive …

Prioritizing Effort Allocation in a Multiple-Goal Environment
… the effect of goal-performance discrepancies (GPDs) on task prioritization was mediated by self-efficacy. Further the amount of time remaining before a deadline moderated the relationship between GPD and task prioritization, although the form of this relationship was not in the proposed …

Inclusive and Exclusive Compton Processes in Quantum Chromodynamics
… scattering. Generalized parton distributions (GPDs) may be observed in hard exclusive reactions such as deeply virtual Compton scattering. We develop an extension of this particular process into the weak interaction sector. We also investigate a possible application of the GPD formalism to …

Self-Regulation in a Simultaneous, Multiple-Goal Environment
… toward task goals. Results indicated that GPDs predicted goal revision direction and magnitude, and that controllability attributions moderated the GPD – revision relation. GPD size determined prioritization between tasks, as did self-efficacy. Mixed results were found for self-efficacy …

Electroproduction of Phi(1020) Mesons at High Q² with CLAS
This analysis studies the reaction ep → e′p′ϕ in the kinematical range 1.6 ≤ Q² ≤ 3.8 GeV² and 2.0 ≤ W ≤ 3:0 GeV at CLAS. After successful signal identification, total and differential cross sections are measured and compared to the world data set. Comparisons are made to the predictions of the …

UNCERTAINTY QUANTIFICATION IN DOWNSCALING OF PRECIPITATION EXTREMES AND ITS APPLICATION TO NEW ENGLAND
