NMR blood flow imaging using multiecho, phase contrast sequences.

Abstract: Moving nuclei, in contrast to stationary nuclei, experience a phase shift in the presence of a balanced gradient. Monitoring of this phase shift can be used to measure the flow velocity of moving nuclei. A specific scan sequence for blood flow imaging is presented. This sequence uses multiple echoes as well as a phase contrast approach to generate both conventional anatomical images and blood flow images from the same data. Images of a phantom and a human volunteer demonstrating the accuracy of the method are presented.

Ultraviolet curable epoxy silicone coating compositions

Abstract: Epoxy functional diorganosiloxane fluids are combined with bis-aryl iodonium salts, particularly linear alkylate bis-dodecylphenyl iodonium salts to form a silicone coating composition effective for rendering surfaces non-adherent to other surfaces which would normally adhere thereto, and which will cure to a final non-adherent state upon brief exposure to ultraviolet radiation. Adhesion of the silicone coating to a substrate can be improved with the addition of β-(3,4-epoxycyclohexyl)ethyltrimethoxy silane.

Using multiple knowledge sources for word sense discrimination

Abstract: This paper addresses the problem of how to identify the intended meaning of individual words in unrestricted texts, without necessarily having access to complete representations of sentences. To discriminate senses, an understander can consider a diversity of information, including syntactic tags, word frequencies, collocations, semantic context, role-related expectations, and syntactic restrictions. However, current approaches make use of only small subsets of this information. Here we will describe how to use the whole range of information. Our discussion will include how the preference cues relate to general lexical and conceptual knowledge and to more specialized knowledge of collocations and contexts. We will describe a method of combining cues on the basis of their individual specificity, rather than a fixed ranking among cue-types. We will also discuss an application of the approach in a system that computes sense tags for arbitrary texts, even when it is unable to determine a single syntactic or semantic representation for some sentences.

Criterion for Registration in Dielectric Track Detectors

Abstract: Dielectric track detectors have a sharp threshold for track registration that depends on the atomic number and the energy of the bombarding particles. New data on track registration in muscovite mica, Lexan polycarbonate, and cellulose nitrate contradict the previously proposed empirical criterion that tracks are formed if the total rate of energy loss exceeds a critical value that is characteristic of the solid. In contrast, the ion explosion spike mechanism for track formation predicts that a solid will record tracks if the rate of primary ionization exceeds a critical rate for that solid. All the known experimental measurements are consistent with this criterion.
