Let GR denote the real points of a connected complex reductive algebraic group defined over R). (For the basic results on cells below, this class of groups is unnecessarily restrictive. But we shall need the assumption when we discuss unipotent representations below.) Let gR denote the Lie algebra of GR and write g for the complexification of gR. Let KR denote a maximal compact subgroup in G, a...

Consumers’ attention limitations give firms incentives to manipulate prospective buyers’ allocation of attention. This paper models such attention manipulation and shows that it limits the ability of disclosure regulation to improve consumer welfare. Competitive information supply, from firms competing for attention, can reduce consumers’ knowledge by causing information overload. A single firm...

Objective Cardiac P MRS is a potentially highly useful tool for probing cardiac energetics and informing clinical management of heart disease, but whose precision suffers from low signal to noise ratio and overlapping peaks. In addition, however, valuable information describing the variance of a spectrum’s fitting remains unused or ineffectively used when determining changes in cardiac PCr/ATP ...

Complex systems such as ecosystems, electronic circuits, lasers or chemical reactions can be modelled by dynamical which typically experience bifurcations. Transients suffer extremely long delays at the vicinity of bifurcations and it is also known that these transients follow scaling laws bifurcation parameter gets closer value in deterministic systems. The mechanisms involved local are well-k...
