Equivalence of Nonstatic Two-Pion-Exchange Nucleon-Nucleon Potentials

, 1999
Off-shell aspects of the one-pion-exchange potential and their relationship to different forms of the nonstatic (subleading-order) chiral two-pion-exchange nucleon-nucleon potential are discussed.

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 ...

Information on the structure of the rho meson from the pion form-factor

, 2009
The electromagnetic pion form-factor is calculated in a Bethe-Salpeter approach which accounts for pion rescattering. In the scattering kernel the pion-pion contact interaction from lowest-order chiral perturbation theory is considered together with an ...

Barriers and Facilitators in Implementing Clinical Practice Guidelines Among Nurses in Emergency Departments and Critical Care Units: A Systematic Review

Journal of Clinical Nursing, EarlyView.
ABSTRACT Aim This systematic review explored the barriers and facilitators to the implementation of clinical practice guidelines (CPGs) among nurses in emergency departments (EDs) and critical care units (CCUs). Design Systematic review. Method A systematic review was performed using both qualitative and quantitative studies from five databases (CINAHL,

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

, 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.

Pion-Pion Interaction and Pion Production in Pion-Nucleon Collision [PDF]

Progress of Theoretical Physics, 1960
The evidence for the n;-n; interaction is investigated by considering the angular distribution of nucleon in pion production by pion-nucleon collision. It is shown that it will be quite difficult to understand the sharp forward angular distribution of nucleon without considering n;-n; interaction.

Narcissism Is Associated With Blunted Error‐Related Brain Activity

Journal of Personality, EarlyView.
ABSTRACT Objective Narcissism is associated with self‐enhancement and social antagonism, yet its neural underpinnings, particularly in error processing, remain underexplored. Competing theoretical models, such as the mask model and the metacognitive model, offer conflicting hypotheses regarding how narcissism influences early neural responses to errors.

Le vote blanc et nul en Wallonie : analyse écologique et individuelle

Belgeo, 2010
Blank and null votes are probably the electoral behaviour least taken into account by electoral studies. Though, in a democracy like Belgium, these votes are far from negligible and offer an untypical geography which underlines border areas.

Pion Superfluidity and Meson Properties at Finite Isospin Density

, 2009
We investigate pion superfluidity and its effect on meson properties and equation of state at finite temperature and isospin and baryon densities in the frame of standard flavor SU(2) NJL model.

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

Progress of Theoretical Physics, 1962
The reaction pi + N yields 2 pi + N is discussed. The production process is assumed to take place mainly via pi - pi interactions, which are studied using an extrapolation formula (G. F. Chew and F. E. Low, Phys. Rev., 113: 1640 (1959)). A program giving a consistent explanation to the process at 0.3 to 1.5 Bev is presented.
