Role of isospin dependent mean field in pion production in heavy ion reactions [PDF]

open access: yes, 1997
The importance of a isospin dependent nuclear mean field (IDMF) in regard to the pion production mechanism is studied for the reaction $Au+Au$ at 1 GeV/nucleon using the Quantum Molecular Dynamics (QMD) model.

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection

open access: yesAdvanced Science, EarlyView.
Finite refractive indices of naturally existing materials place a fundamental ceiling on the momentum of detectable particles in traditional Cherenkov detectors. This work demonstrates transverse‐electric graphene plasmon Cherenkov radiation, breaking the momentum barrier for particle detection beyond the TeV scale with exceptional robustness and ...

L'abstentionnisme électoral en Belgique : données individuelles et agrégées à Charleroi

open access: yesL'Espace Politique, 2011
Electoral absenteeism is a common studied subject in the Anglo-Saxon and French scientific world. But researches about it in Belgium, where voting is compulsory are not far from being null.

Pion Form Factor in Chiral Limit of Hard-Wall AdS/QCD Model

open access: yes, 2007
We develop a formalism to calculate form factor and charge density distribution of pion in the chiral limit using the holographic dual model of QCD with hard-wall cutoff. We introduce two conjugate pion wave functions and present analytic expressions for

The Immune Microenvironment in Liver Cancer: From Analysis to Targeting

open access: yesAdvanced Science, EarlyView.
This review explores how smart nanomedicines overcome the immunosuppressive tumor microenvironment in liver cancer. It details targeted delivery strategies and immune reprogramming mechanisms, including remodeling abnormal physiology, modulating metabolism, and inducing immunogenic cell death. The article highlights the paradigm shift toward multimodal

Proton and pion distribution functions in counterpoint

open access: yesPhysics Letters B, 2022
Working with proton and pion valence distribution functions (DFs) determined consistently at the same, unique hadron scale and exploiting the possibility that there is an effective charge which defines an evolution scheme for DFs that is all-orders exact,

Bose-Einstein Correlations of Three Charged Pions in Hadronic Z^0 Decays [PDF]

open access: yes, 1998
Bose-Einstein Correlations (BEC) of three identical charged pions were studied in 4 x 10^6 hadronic Z^0 decays recorded with the OPAL detector at LEP. The genuine three-pion correlations, corrected for the Coulomb effect, were separated from the known ...

Energy Profile and Hopping Barriers for Small Electron Polarons at Ferroelectric Domain Walls in Bismuth Ferrite from First Principles

open access: yesphysica status solidi (b), EarlyView.
An electron polaron in bismuth ferrite needs to overcome an energy barrier to hop from initial iron site Fe1 to final iron site Fe2. Here, this energy barrier was determined ab initio for hops in perfect bismuth ferrite and at neutral ferroelectric domain walls.

Effect of bicarbonate buffer on artificial membrane permeation of drugs

open access: yesADMET and DMPK
Background and purpose: The pH value of the small intestine is physiologically maintained by bicarbonate buffer (BCB). However, the effect of BCB on the membrane permeation of drugs has not been investigated. The purpose of this study was to investigate
