This paper presents an approach to shadow removal that preserves texture consistency between the original shadow and lit area. Illumination reduction in the shadow area not only darkens that area, but also changes the texture characteristics there. We achieve textureconsistent shadow removal by constructing a shadow-free and textureconsistent gradient field. First, we estimate an illumination c...

The present study examined functional MRI (fMRI) BOLD signal changes in response to object categorization during response selection and inhibition. Young adults (N=16) completed a Go/NoGo task with varying object categorization requirements while fMRI data were recorded. Response inhibition elicited increased signal change in various brain regions, including medial frontal areas, compared with ...

BACKGROUND AND PURPOSE We performed a retrospective analysis of the prognostic factors in patients treated with local intra-arterial thrombolysis (LIT). The purpose of this study was to evaluate the safety and efficacy of LIT using urokinase in patients with acute ischemic stroke of the anterior or posterior circulation and to determine the influence of clinical and radiological parameters on o...

BACKGROUND Achieving lifelong tobacco abstinence is an important public health goal. Most studies use 1-year follow-ups, but little is known about how good these are as proxies for long-term and life-long abstinence. Also, intervention intensity is an important issue for development of efficient and cost-effective cessation treatment protocols.The study aims were to assess the long-term effecti...

T he hydrated electron, an electron in aqueous solution, has captured the attention of scientists since it was discovered in 1962 as a product of water radiolysis 1. Many properties of the hydrated electron are consistent with the 'cavity' model, in which it resides in a non-spherical solvent cavity with an average radius of ~2.4 Å and is stabilized by hydrogen-bonding interactions with, on ave...

Anagyrus sp. nov. nr. sinope Noyes and Menezes (Hymenoptera: Encyrtidae) is a candidate for biological control of theMadeiramealybug,PhenacoccusmadeirensisGreen (Hemiptera: Pseudococcidae). P. madeirensis is a serious pest of horticultural crops in the southeastern United States. The Þrst experiment studied the effect of temperature (15, 20, 25, 30, and 35 C) and feeding treatment (starved, hyd...

Most of what is known about the structure of the hydrated electron comes from mixed quantum/classical simulations, which depend on the pseudopotential that couples the quantum electron to the classical water molecules. These potentials usually are highly repulsive, producing cavity-bound hydrated electrons that break the local water H-bonding structure. However, we recently developed a more att...
