Chitosan–Alginate Polyelectrolyte Systems: From Classical Release Models to the D‐PARMO Framework

open access: yesMacromolecular Materials and Engineering, Volume 311, Issue 5, May 2026.
Classical empirical models fail to predict the dynamic in vivo behavior of chitosan‐alginate nanocarriers. Bridging this translational gap, the novel D‐PARMO framework replaces purely descriptive curve‐fitting with a mechanistically informed operational model.

On the impact of mass difference between the pions (π±-π0) and the nucleons (n-p) on the charge independence breaking of nuclear forces

open access: yesЯдерна фізика та енергетика, 2017
Charge dependence of the pion-nucleon coupling constants and the 1S0-state low-energy nucleon-nucleon scattering parameters are studied on the basis of the Yukawa meson theory.

Neutrino-induced coherent pion production off nuclei reexamined

open access: yes, 2009
It is pointed out that so far all theoretical estimates of coherent pion production off nuclei induced by neutrinos rely on the 'local approximation' well known in photonuclear physics. The effects of dropping this approximation are discussed.

The pion electromagnetic form-factor in a QCD-inspired model [PDF]

open access: yes, 2004
We present detailed numerical results for the pion space-like electromagnetic form factor obtained within a recently proposed model of the pion electromagnetic current in a confining light-front QCD-inspired model. The model incorporates the vector meson

Optimal 1TEL–target protein linker character is target protein‐dependent

open access: yesActa Crystallographica Section D, Volume 82, Issue 5, Page 516-532, May 2026.
In this study, we examine the effect of short to medium‐length flexible, semi‐flexible and rigid linkers on the crystallization of a DARPin or the TNK1 UBA domain fused to the 1TEL protein crystallization chaperone, demonstrating that while rigid linkers can impair crystallization and reduce diffraction quality, the ideal linker character remains ...

Evaluation of the two lightest quark masses

open access: yesЯдерна фізика та енергетика, 2017
Simple relations between the masses of the two lightest up and down quarks were obtained on the basis of the simple physically based model compatible with the present-day theory of strong interactions, i.e. with quantum chromodynamics.

Pion-Nucleon Scattering and Pion-Pion Interaction [PDF]

open access: yesProgress of Theoretical Physics, 1962
Applying Cini-Fubini approximation to the Mandelstam representation for pion-nucleon scattering amplitude, we treat explicitly the effect of pion-pion interaction to be added to the dispersion relation given by Chew, Goldberger, Low and Nambu. On account of scanty information on the contribution to tl:e dispersion .integral from high-mass states, we ...

Virtual-pion and two-photon production in pp scattering

open access: yes, 2002
Two-photon production in pp scattering is proposed as a means of studying virtual-pion emission. Such a process is complementary to real-pion emission in pp scattering.

Pion transverse-momentum spectrum and elliptic anisotropy of partially coherent source

open access: yesPhysics Letters B, 2018
In this letter, we study the pion momentum distribution of a coherent source and investigate the influences of coherent emission on the pion transverse-momentum (pT) spectrum and elliptic anisotropy.
