In this paper, we describe the system we used for the TREC Question Answering Track. For factoid and list questions two different approaches were exploited: A redundancy-based approach using a modified version of aranea and a parse-tree based unifier. The modified version of aranea essentially uses Google snippets for extracting answers and then projects them to aquaint. The parse-tree based un...

An infrared radiation-detecting system was used to measure initial heat production in bull frog sartorius muscle at 15 degrees C. Numerous tests with the system showed that thermal artifacts were not noticeable. Many previous measurements with myothermic thermopiles were corroborated with this method. In addition, a cooling phase as large as 0.39 of peak exothermicity was found during and after...

We studied electrostatic charging of ice films induced by the impact of 1−200-keV Ar+ ions and their subsequent discharging postirradiation. We derived the positive surface electrostatic potential from the kinetic energy of sputtered molecular ions and with a Kelvin probe. Measurements were performed as a function of film thickness, temperature, and ion energy. Charging requires that the projec...

continuing this treatment contrasts with good comfort care at the end of life.3-5 Research since Edna shows that medically supplied nutrition and hydration does not improve survival among patients with advanced dementia, and increases the risks of aspiration, pneumonia, and gastrointestinal discomfort.6-10 Since the Nancy Cruzan and Terri Schiavo cases in the 1990s, many medical organizations h...

Chapter 15 Social dynamics at work: Meetings as a gateway Annika L. Meinecke TU Braunschweig Nale Lehmann-Willenbrock VU University Amsterdam, the Netherlands Abstract Meetings offer an exciting gateway to dynamic social processes in organizations. During their meeting interactions, employees exchange information, build common ground, create new ideas, manage relationships, and make or break te...

The prediction of spectral water leaving radiance and remote sensing reflectance from a coupled physical/ecological/optical simulation is one of the goals of the ONR Hyperspectral Coastal Ocean Dynamics Experiment (HyCODE). This goal requires coupling a high-resolution circulation model (ROMS) to provide realistic physical forcing to a dynamic ecological model that produces depth-dependent dist...

This report aims to identify factors which are related to use of oral contraceptives at an early age. A self-administered questionnaire was completed at schools in 1988 and 1992 in southern and western Finland (N = 1339). Sexually experienced girls (mean age 15.8 years) who had answered the question concerning their oral contraceptive use were included (N = 389). Logistic regression analysis wa...
