We review how nuclear forces emerge from low-energy QCD via chiral effective field theory.
The presentation is accessible to the non-specialist. At the same time, we also provide …

Cognition can be defined as computation over meaningful representations in the brain to
produce adaptive behaviour. There are two views on the relationship between cognition and …

This discussion shows that a new approach to an enlarged definition (or view or notion) will
likely empower us to more effectively consider different notions of value across research or …

How should firms decide whether and when to invest in new capital equipment, additions to
their workforce, or the development of new products? Why have traditional economic models …

An effort has been made to present the various topics in the theory of graphs in a logical
order, to indicate the historical background, and to clarify the exposition by including figures …

The relativistic S-matrix formalism of Feynman is applied to the bound-state problem for two
interacting Fermi-Dirac particles. The bound state is described by a wave function …

Order α 6 mc 2 corrections to the fine structure splitting of the deepest triplet P state (2 3 P 0,
1, 2) of the He 4 atom have been investigated. The investigation is based on the covariant …

Abstract Ideas and techniques known in quantum electrodynamics have been applied to the
Bardeen-Cooper-Schrieffer theory of superconductivity. In an approximation which …

The statistical dynamics of a classical random variable that satisfies a nonlinear equation of
motion is recast in terms of closed self-consistent equations in which only the observable …
