Organic-inorganic hybrid mesoporous silica materials and their application as host matrix for protei
Transparent, organic-inorganic hybrid mesoporous silica materials have been prepared successfully via the acid-catalyzed hydrolysis and cocondensation of tetramethyl orthosilicate and various organosiloxanes via the nonsurfactant templated sol-gel process. The organic groups were attached to the silica matrix via the non-hydrolyzable Si-C covalent bond and functioned as network modifier. The synthetic conditions have been systematically studied and optimized. Nitrogen adsorption and transmission

Authoring Intelligent Tutoring Systems:
An analysis of the state of the art
This paper consists of an in-depth summary and analysis of the research and development state of the art for intelligent tutoring system (ITS) authoring systems. A seven-part categorization of two dozen authoring systems is given, followed by a characterization of the authoring tools and the types of ITSs that are built for each category. An overview of the knowledge acquisition and authoring techniques used in these systems is given. A characterization of the design tradeoffs involved in buildi
The Microsoft Case
Professors Lessig and Zittrain will teach a research seminar on the Microsoft case. The seminar will meet at least once a week, beginning the week of 9/21. It will review the proceedings leading up to the present antitrust action, and then shadow the current trial. We will collect transcripts from the case, which will be assigned each week, as well as other readings to be determined. In addition to the ultimate question of liability, we will consider whether there are special issues that cybersp
