Toroid moments in electrodynamics and solid-state physics
Physics Reports, 1990The role is explained of toroid moments and average 2n-power radii in the structure of multipole expansions in the framework of Maxwell-Lorentz electrodynamics. A complete scheme of multipole expansions is given in terms of distribution theory. A number of particular applications of toroid moments is considered in condensed-matter physics.

Physics of charmed baryons and their magnetic moments
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1996Abstract The extant quark and soliton model as well as chiral perturbation theory based predictions of the spectra and magnetic moments of the charmed hyperons are described, along with their theoretical foundations in QCD. The differences between the predictions obtained by different methods are emphasized.

Physical electroweak anapole moment for the neutrino
Physical Review D, 1999We calculate the neutrino anapole moment in the context of the standard model of the electroweak interactions and we show that this quantity is infinite and gauge dependent in this model. We define the electroweak anapole moment of the neutrino ${a}_{{\ensuremath{\nu}}_{l}}^{\mathrm{EW}}$ through the ${\ensuremath{\nu}}_{l}{l}^{\ensuremath ...

Just a moment—a modelling exercise for physics
European Journal of Physics, 2006This paper addresses the seemingly simple concept of turning moments. The approach taken is to set the learning in the context of the action of the biceps brachi or muscle of the upper arm. A simple laboratory exercise can be used to generate data and these data can then be modelled mathematically. Real data, from muscle activity, can then be collected

The Cyber-Physical Policy Moment
2020This concluding chapter argues that privacy and security have to take primacy as aspirational values as networks shift from digital only to directly embedded in the physical world. It calls for various stakeholders to urgently take serious cyber-physical policy choices and collectively elevate cybersecurity as a generational imperative necessary for ...

Generalized-moments: Application to solid-state physics
1985In condensed-matter physics, the density of eigenstates n(E) of hermitian operators is often computed using continued-fraction expansions of the Hilbert transform of n(E). The framework of this technique is briefly reviewed in the present paper. Emphasis is given on the generalized-moments method, intimately related to orthogonal polynomials.

Analytical Tire Forces and Moments with Physical Parameters
Tire Science and Technology, 2008Abstract The pneumatic tire behaves as a highly nonlinear system. Its complexity has limited the development of a complete and reasonable theory governing its mechanics. Practical tire models used in vehicle dynamics simulation and tire-related research rely basically on curve-fitted experimental data and empirical adjustments of ...

Moments of certain stochastic integrals occurring in mathematical physics
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1992SynopsisWe give an expression for the n-th moment of certain Itô integrals. The integrands considered are nonanticipating functionals of the form s↦a(s, Xs), where a is a measurable time-dependent vector field in space satisfying mild regularity conditions, and Xs is standard translated Brownian motion. The expressions are similar to the Dyson-Phillips
