Abstract: Improved computer modeling techniques, and uses thereof, are described herein. A set of unstructured textual data is received. Certain textual data is removed from the set of unstructured data to form an initial vocabulary set of textual data. One or more bigrams are added to the vocabulary set of textual data to form a final vocabulary set of textual data. The final vocabulary set of textual data is divided into a plurality of subsets of textual data based on type. A model is trained using each of the plurality of subsets of textual data to form a plurality of trained models, each corresponding to one of the types.

Abstract: A multiwell plate is described herein that can be used in cell-based applications and is made from a plastic upper plate which forms the sidewalls of one or more wells and a glass lower plate which forms the bottom walls of the wells. The plastic upper plate and glass lower plate are attached and bound to one another by a cationically photocured adhesive. A preferred cationically photcured adhesive includes: (1) one or more photocationally polymerizable epoxy and/or oxetane functional resins; (2) a low fluorescing cationic photoinitiator; and (3) a low fluorescing photosensitizer if the cationic photoinitiator does not have an adequate absorption at a wavelength >280 nm to initiate cure. Also described herein is a method for making such multiwell plates.

Abstract: Fiber optic articles, assemblies, and cables preserve optical performance by using optical waveguides having a core, a cladding, and a coating system according to the present invention. Moreover, the optical articles, assemblies, and cables of the present invention may achieve performance levels that were previously unattainable, for instance, the present invention contemplates acceptable optical performance for wavelengths such as 1625 nm and higher. Additionally, articles, assemblies, and/or cables of the present invention advantageously preserve optical performance, i.e., have relatively low delta attenuation, when subjected to manufacturing processes and/or environmental conditions such as temperature cycling. In other words, the articles, assemblies, and cables can withstand increased stress/strain before having significant attenuation.
