The pion charge radius from charged pion electroproduction [PDF]
, 2000 We analyze a low-energy theorem of threshold pion electroproduction which allows one to determine the charge radius of the pion. We show that at the same order where the radius appears, pion loops induce a correction to the momentum dependence of the ...

Proton First: Rationalizing a Proton Transfer in a Protein‐Fragment Complex
ChemMedChem, Volume 20, Issue 20, October 15, 2025.We combine experimental and theoretical approaches to investigate benzoic acid binding to Protein Kinase A. The crystal structure shows benzoic acid protonated in the complex. Isothermal titration calorimetry (ITC) fails to detect binding, likely due to low affinity.

Dalitz plot studies of D0 → KS0π+π− decays
EPJ Web of Conferences, 2012 The availaible data on the D0 → KS0π+π− decays are analysed in the framework of the quasi two-body QCD factorization approximation. The annihilation, via Wexchange, amplitudes are added to the weak-decay tree amplitudes.

The charged and neutral pion masses revisited
Physics Letters B, 2019 Results from neutrino mass and oscillation experiments now set the mass of the muon neutrino to less than 2 eV/c2. This fact, together with our former measurement of the muon momentum in pion decay at rest, pμ+=(29.79200±0.00011) MeV/c, allows us to ...

Nonequilibrium Pion Distribution within the Zubarev Approach
Particles, 2020 We discuss how the non-equilibrium process of pion production within the Zubarev approach of the non-equilibrium statistical operator leads to a theoretical foundation for the appearance of a non-equilibrium pion chemical potential for the pion ...

Initial three‐ and half‐year machine performance assessment of a superficial radiation therapy unit
Journal of Applied Clinical Medical Physics, Volume 26, Issue 10, October 2025.Abstract Purpose This work reports on results of periodic machine quality assurance (QA) tests for our superficial radiation therapy (SRT) unit (SRT‐100 Vision) performed for the first three‐ and half‐ year. Methods Results of machine warm‐up, dosimetry, mechanical, safety and imaging QA tests for our SRT‐100 Vision unit were reviewed and analyzed ...

An improved hadronic model for pion electroproduction
Physics Letters B, 2020 Current measurements of the high energy behavior of the pion form factor are obtained from pion electroproduction data. These values are model dependent, utilizing the Vanderhaeghen, Guidal and Laget Regge (VGL) Model for their extraction.

PION–PION SCATTERING ABOVE RESONANCES [PDF]
Meson 2002, 2003 We model large angle intermediate energy pion-pion scattering by the pQCD two-gluon (2g) exchange contribution and discuss the onset of the dominance of the Glauber-Gribov-Landshoff (GGL) component. The pQCD 2g exchange contribution becomes substantial already at $|t|\sim$ 1 GeV^{2}, but the pQCD exchange dominance is deferred to $|t|\sim$ 3 GeV^{2 ...

Auditory and Semantic Processing of Speech‐in‐Noise in Autism: A Behavioral and EEG Study
Autism Research, Volume 18, Issue 10, Page 2011-2030, October 2025.ABSTRACT Autistic individuals often struggle to recognize speech in noisy environments, but the neural mechanisms behind these challenges remain unclear. Effective speech‐in‐noise (SiN) processing relies on auditory processing, which tracks target sounds amidst noise, and semantic processing, which further integrates relevant acoustic information to ...
