Velocity-Dependent Nuclear Potentials for Singlet-Even States

Physical Review, 1962
The usual models for the two-nucleon interaction involve a potential which includes a repulsive hard core at short distances and as a result, the treatment of the many-body problem is mathematically complicated. Peierls, Levinger, and others have suggested that ordinary perturbation theory may be useful if the two-body interaction can be described by a

Proposed Weber potential with absolute velocities

Foundations of Physics Letters, 1995
The Weber potential U is limited to relative velocities between charges V less than\(\sqrt {2c} \) and fails when V→2c. If the relative velocity of action between charges is c, then U equals the root-mean-square average of the retarded and advanced Coulomb potential.

Biotic Velocity Identifies Potential Climate Refugia Beyond Climate Velocity Estimates

Global Ecology and Biogeography
ABSTRACT Aim Climate velocity is commonly used to identify potential climate refugia, yet this climate‐only metric overlooks species‐specific ecological and dispersal constraints, and thus may fail to reveal the actual biotic velocity required to track shifting climates under different ...

Influence of intracellular potential and conduction velocity on extracellular muscle fibre potential

Journal of Electromyography and Kinesiology, 1993
The influence of alterations in intracellular action potential (ICAP) duration and in muscle fibre conduction velocity (CV) on the extracellular action potential (ECAP) duration was studied. The experiments were carried out on frog isolated skeletal muscle fibres.

Statistical mechanics of velocity-dependent potentials

Nuclear Physics, 1965
Abstract We consider the statistical mechanics of a system in which the particles interact through a velocity-dependent potential, of the form p ij V(| r ij |)· p ij ( p ij is the relative momentum of the i th and j th particles ) .

Muscle action potential propagation velocity changes during activity

Muscle & Nerve, 1988
AbstractFatigue from high frequency stimulation is associated with EMG signal changes, which are primarily due to a slowing of the sarcolemma conduction velocity. In the present study, in which isolated mouse soleus and extensor digitorum longus muscles have been studied, it is shown that the action potential propagation velocity is (1) decreased by an

The Stream Function and the Velocity Potential Function

The Mathematical Gazette, 1954
The stream function, ψ, is a function specially suited for dealing with two-dimensional flow while the velocity potential, ϕ, is a function which may be used with either two- or three-dimensional flow. In two-dimensional flow, the chief utility of ψ and ϕ occurs when they satisfy Laplace's equation ∇

Velocity-Dependent Nucleon-Nucleon Potentials

1963
An investigation is carried out to see whether a nonsingular two-nucleon velocity-dependent potential can give similar results as those of a model hard-core potential in the a-state in nuclear-matter. Reasons for failure of some earlier velocity-dependent model potentials to give saturation in nuclear-matter at reasonable densities are examined and a ...
