A bstract We show that barotropic flows of a perfect, charged, classical fluid exhibit an anomaly analogous to the chiral known in quantum field theories with Dirac fermions. prominent effect is transport electric current at equilibrium reservoir. find it also property celebrated Beltrami — stationary solutions Euler equation extensive helicity.

Critics of psychological measurement have accused quantitative psychologists ignoring the empirical hypothesis that phenomena are (Michell), or claimed it is impossible in principle to find out whether actually (Trendler). By drawing on Bennett and Hacker (2003), I argue both criticisms do not go far enough because they sidestep fundamental conceptual problem debate: It give concrete formulatio...

Receptor-stimulated phosphatidylinositol (Ptdlns) metabolism was discovered by Hokin & Hokin in 1953 and substantially characterized by the same workers during the following few years (see Hawthorne, 1960). However, the function of this response remained obscure until Michell (1975) realized that it might in some way be responsible for the receptor-stimulated elevation in the cytoplasmic concen...

Dual conservation laws of linear planar elasticity theory have been systematically studied based on stress function formalism. By employing generalized symmetry transformation or Lie–B€acklund transformation, a class of new dual conservation laws in planar elasticity have been discovered based on Noether theorem and its Bessel–Hagen generalization. These dual conservation laws represent variati...

Composing services makes sense only if they are compatible, i.e. composition does not lead to problems such as livelocks or deadlocks. In general, compatibility can be checked using state space explorations on any kind of formal models of services. Petri nets, one of the formal models in use, offer a rich theory for reasoning without exploring a state space. Among the techniques is the so-calle...

Only some special open surfaces satisfying the shape equation of lipid membranes can be compatible with the boundary conditions. As a result of this compatibility, the first integral of the shape equation should vanish for axisymmetric lipid membranes, from which two theorems of nonexistence are verified: (i) there is no axisymmetric open membrane being a part of torus satisfying the shape equa...
