Buying stocks with low dispersion in analysts earnings forecasts and selling stocks with high dispersion yields statistically significant and economically large payoffs (Diether, Malloy, and Scherbina (2002)). • This negative relation between dispersion and returns (dispersion effect

ABSTRACT Paramagnetic deoxyhemoglobin in venous blood is a naturally occurring contrast agent for magnetic resonance imaging (MRI). By accentuating the effects of this agent through the use of gradient-echo techniques in high fields, we demonstrate in vivo images of brain microvasculature

For wireless cellular communication systems, one seeks a simple effective means of power control of signals associated with randomly dispersed users that are reusing a single channel in different cells. By effecting the lowest interference environment, in meeting a required minimum signal

of a composed object to an external, real photon field of arbitrary energy. Being energy dependent, they therefore contain additional information about dispersive effects induced by internal relaxation mechanisms, baryonic resonances and meson production thresholds of the nucleon. We give explicit

In this paper we present a stochastic add–on extension to standard raytracing which makes it possible to render dispersion effects more efficiently than hitherto possible. Our method incurs less overhead than previous proposals, is physically accurate and is applicable to most of the currently

Abstract. The explicit energy dependence of the single particle self-energy (dispersive effects), due to short range correlations, is included in the treatment of neutron matter superfluidity. The method can be applied in general to strong interacting fermion systems, and it is expected to be valid

Abstract. Oil spill dispersant, as a kind of effective measures to deal with oil spill, has been widely used, but the effectiveness still needs more investigations. In this paper, what factors influenced the dispersant effectiveness was studied in the tank with the action of waves of different time

The effect of surfactant composition on the percent of oil dispersed in sea water One approach in reducing the adverse effects of oil spills is to introduce chemical dispersants, reduce the toxicity of the crude oil by reducing its concentration. Dispersants are composed of surfactants, including

The packet pair technique estimates the capacity of a path (bottleneck bandwidth) from the dispersion (spacing) experienced by two back-to-back packets [1][2][3]. We demonstrate that the dispersion of packet pairs in loaded paths follows a multimodal distribution, and discuss the queueing effects
