Internal structure of the Tcc(3875)+ from its light-quark mass dependence

open access: yesPhysics Letters B
We employ a chiral effective field theory-based approach to connect DD⁎ scattering observables at the physical and variable pion masses accessible in lattice QCD simulations.

Nonperturbative partonic quasidistributions of the pion from chiral quark models

open access: yesPhysics Letters B, 2017
We evaluate nonperturbatively the quark quasidistribution amplitude and the valence quark quasidistribution function of the pion in the framework of chiral quark models, namely the Nambu–Jona-Lasinio model and the Spectral Quark Model.

Determination of the pion distribution amplitude

open access: yes, 2013
Right now, we have not enough knowledge to determine the hadron distribution amplitudes (DAs) which are universal physical quantities in the high energy processes involving hadron for applying pQCD to exclusive processes.

Commissioning of a 142.4 MeV ultra‐high dose rate (UHDR) proton beamline in a synchrotron‐based proton therapy system

open access: yesMedical Physics, Volume 52, Issue 7, July 2025.
Abstract Background Recent studies suggest that radiotherapy at ultrahigh dose rates (>40 Gy/s, FLASH) offers normal tissue sparing effects while maintaining tumor control. There is significant interest in preclinical studies investigating the mechanism of FLASH sparing effects.

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.

Artificial Endosymbiosis of Pedobacter sp. DDGJ Boosts the Growth Potential, Stress Resistance and Productivity of Morchella Mushrooms

open access: yesMicrobial Biotechnology, Volume 18, Issue 7, July 2025.
This study introduced Pedobacter sp. DDGJ into morel hyphal cells and determined the effect of artificial endosymbiosis on morel growth, stress resistance and productivity. ABSTRACT True morels are precious edible and medicinal mushrooms. The sustainable development of morel cultivation necessitates urgent breeding programmes to develop improved ...

An improved hadronic model for pion electroproduction

open access: yesPhysics 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.

Design and validation of an electroencephalogram‐supported approach to tracking real‐time cognitive load variations for adaptive video‐based learning

open access: yesBritish Journal of Educational Technology, Volume 56, Issue 4, Page 1553-1572, July 2025.
Cognitive load is a critical internal state associated with learners' learning process and significantly influences learning outcomes. With the worldwide popularity of video‐based learning (VBL), tracking real‐time cognitive load variations becomes more and more important for the timely provision of adaptive learning support during the learning process.

Medium effects on pion production in heavy ion collisions [PDF]

open access: yes, 2017
Within the framework of the relativistic Vlasov-Uehling-Uhlenbeck transport model based on the relativistic nonlinear NL$\rho$ interaction, we study pion in-medium effects on the $\pi^-/\pi^+$ ratio in Au+Au collisions at the energy of $E/A=400~\mathrm ...
