The physics of a locked magnetic island chain maintained in the pedestal of an H-mode tokamak plasma by a static, externally generated, multi-harmonic, helical magnetic perturbation is investigated. The non-resonant harmonics of the external perturbation are assumed to give rise to significant toroidal flow damping in the pedestal, in addition to the naturally occurring poloidal flow damping. F...

In neoclassical theory, product differentiation provides consumers with a variety of different products within a particular industry, rather than a homogeneous product that characterizes purely competitive markets. The welfare-enhancing benefit of product differentiation is the greater variety of products available to consumers, which comes at the cost of a higher average total cost of producti...

with τe being the electron collision time. nEQ is an equilibrium density associated with neoclassical fields and currents. K (nEQ) =−∇qJPS, which in turn is driven by the corresponding neoclassical potential JPS = 1 C (φPS). The contribution of impurities to the gross plasma density ni,0 is assumed to be negligible, i. e. ni = ni,0+nimp ≈ ni,0. For cold impurities the ion-drift velocity is give...

Static neoclassical framework cannot be applied to model time dependent processes or increasing returns to scale in production. The dynamization of the neoclassical theory of a firm by dynamic optimization, on the other hand, assumes inconsistent profit functions with the former. As a solution to these problems, we present a dynamic theory of a firm consistent with the static neoclassical theor...

We present a numerical and analytic assessment of the transport in two quasi-axially symmetric stellarators, including one variant of the MHH2 class[l] of such devices, and a configuration we refer t o as NHH2, closely related t o MHH2. Monte Carlo simulation results are compared with expectations from established stellarator neoclassical theory, and with some empirical stellarator scalings, us...

In their recent analysis of the alleged decay in modern economics, Ben Fine and Dimitris Milonakis claim to find its source and origin in the ‘marginal revolution’ of the 1870s. They argue that this development led to ‘methodological individualism’ and the detachment of economics from society and history. I contest their account of the marginal revolution and of the role of Alfred Marshall amon...

We present a detailed analysis of assumptions that J. Bell used to show that local realism contradicts QM. We find that Bell’s viewpoint on realism is nonphysical, because it implicitly assume that observed physical variables coincides with ontic variables (i.e., these variables before measurement). The real physical process of measurement is a process of dynamical interaction between a system ...
