We investigated 4th-grade children's search strategies on sequential search tasks in which the goal is to identify an unknown target object by asking yes-no questions about its features. We used exhaustive search to identify the most efficient question strategies and evaluated the usefulness of children's questions accordingly. Results show that children have good intuitions regarding questions...

BACKGROUND AND PURPOSE A system for the detection, measurement and analysis of the periodic physiological organ motion during radiotherapy treatment is proposed and clinically tested in this paper. MATERIAL AND METHODS The procedure is based on the acquisition of fluoroscopic sequences, followed by an automatic detection of the movement using cross-correlations with matched filters. RESULTS...

Driven by fear of underinvestment in network assets, merchant investment in electricity transmission networks (MTI) is now legally allowed. Given that MTI is a real possibility, regulators face a new set of questions. After classifying different types of MTI, the paper raises and analyses regulatory questions, concentrating on the effect on competition, ownership questions, third-party-access r...

Herein we describe the synthesis of the first Thalidomide-biotin analogue in order to initiate investigations into the unknown molecular mode of action of Thalidomide. In this manner we describe the attachment of biotin tether through the Huisgen 1,3-dipolar cycloaddition or "click" synthetic methodology.
