2/26 -- THURSDAY

10:30 AM - POLYMERS DIVISION SEMINAR: Environmentally and Biologically Responsive Materials Constructed via Peptide Molecule Folding and Self-assembly
We are exploring new methods of materials construction via aqueous molecular self-assembly, specifically peptidic molecule self-assembly. By using peptidic molecules in the self-assembly design process, one can take advantage of inherent biomolecular attributes, namely secondary structure and intramolecular folding events, in addition to more traditional self-assembling molecular attributes such as amphiphilicty, to define hierarchical material structure and consequent properties. The self-assembled nature of the resultant material imparts beneficial rheological properties (e.g. shear thinning, self-healing) for ease of processing. Intramolecular folding events impart an environmental responsiveness in the materials (e.g. drastic viscoelastic changes with changes in pH). The peptidic nature of the constituent molecules provides for desired biological activity (e.g. biocompatibility with mammalian cells, antimicrobial behavior, biodegradability). The utility in material design with two general classes of molecule, block copolypeptides and amphiphilic beta hairpin peptides, will be discussed.

ADVANCE NOTICE

3/4/04 10:00 AM - OFFICE OF THE DIRECTOR, NIST SEMINAR: "Small Molecule Screening & Chemical Genetics at NIH: The Roadmap & Beyond."
With the completion of the human genome sequence has come the opportunity, and the scientific imperative, to determine the function of the large number of proteins encoded by the genome. Recent efforts at NIH, particularly through the Director's Roadmap process, have focused on making small molecule probe compounds available to the research community for this purpose (http://nihroadmap.nih.gov/molecularlibraries/index.asp). The structure, context, and goals of this initiative will be discussed, including description of the component of the screening program that will be based on the NIH campus in Bethesda.

3/5/04 10:30 AM - PHYSICS LABORATORY SEMINAR: Modeling Explosive Epidemics: HIV/AIDS
Mathematical models are crucial for understanding how HIV/AIDS is spread. It has been widely claimed that epidemiological modeling shows that HIV epidemics are dominated by people in their primary stage of infection, i.e., within a couple of months of becoming infected and before antibodies develop. Our models show that late stage is more infectious, i.e., the symptomatic stage, generally seven or so years after becoming infected. We find that the established estimate of the ratio of (late stage infectiousness)/ (primary stage infectiousness) is 100 times too small. When HIV is most infectious is critical to intervention strategies, especially in countries where there is little treatment available. Professor Yorke, along with Benoit Mandelbrot, shared the 2003 Japan prize for his pioneering contributions to chaos theory and the science and technology of complexity.

3/9/04 10:30 AM - INFORMATION TECHNOLOGY LABORATORY SEMINAR: Generative Ontologies For Knowledge Extraction From Text
Development of intelligent decision support systems can be accelerated by knowledge extraction, which aims to automatically populate complex schemas such as cases, lessons, and plans from text documents. In contrast to traditional information extraction techniques that use shallow natural language processing techniques and simple lexicons, knowledge extraction requires a combination of deep natural language techniques and rich lexical resources, which must support robust and accurate interpretation of specialized subject matter text. Popular lexical resources such as WordNet and ontologies such as CyC are representationally inadequate and largely incomplete for processing text in specialized domains (i.e., sublanguage). Consequently, we have extended generative lexicon theory and created one of its first implementations, called generative Sublanguage Ontologies (SO), which provides a rich representation for selecting unanticipated meanings of terms and their novel combinations by applying a small set of sense generation operators. I will describe SO concept representations that include novel entity and event structures within an object-oriented inheritance framework. I will discuss a methodology for representing world knowledge in SO for better interpretation of compound nouns and resolve prepositional attachments. In addition, I will show how SOs concept representation enables morphological semantics to significantly reduce its size and improve text interpretation. Finally, I will describe tools and methodologies to engineer SOs for naval knowledge extraction. Dr. Kalyan Gupta is a Chief Scientist with ITT Industries. He conducts interdisciplinary research for NRL’s IDA Group, focusing on applying AI techniques to knowledge-based decision support systems. Since October 2000 he has worked on the NRL project Language Understanding for Interactive Knowledge Management, where he is focusing on mixed-initiative case-based reasoning (CBR), information extraction, knowledge management, lexicon engineering, document restructuring, and knowledge-based project planning. He previously was Head of Research and Development at CaseBank Technologies Inc., whose product is based on his PhD research. He has authored three U.S. patents, and has published articles in journals such as IEEE Transactions on Systems Man Cybernetics, Decision Support Systems, and Omega, and in reputed national and international conferences. Dr. David Aha leads NRL’s Intelligent Decision Aids (IDA) Group, whose focus is on the research and development of state-of-the-art decision aiding tools that can be transitioned to their sponsors’ organizations. He currently lead and/or participates in projects concerning intelligent lessons learned systems, deviation detection for crisis action planning, hypothesis elaboration for suspected terrorist activities, machine learning testbed for (war)gaming systems, plan de-confliction and air vehicle management, and automated on-road driving simulation. David has published approximately 90 technical contributions, given keynote presentations at several international technical conferences, (co-)organized 13 international conferences/workshops, has served on the editorial boards for JAIR, Machine Learning, and Applied Intelligence, (co-)edited two special journal issues, and serves on several AI conference program committees.

3/26/04 10:30 AM - INTELLIGENT SYSTEMS DIVISION SEMINAR: Expectation-based, Multi-focal, Saccadic (EMS-) Vision for Perception and Control of Vehicle Motion
Over the last six years (1997 – 2003), building on two decades of experience with two generations of vision systems based on the 4-D approach to dynamic vision, the vertebrate-type EMS-vision system has been conceived, built and validated experimentally. The latest results with the two experimental vehicles VaMoRs (a 5-ton van) and VaMP (a sedan Mercedes 500 SEL) will be discussed. A new level of active gaze control and the explicit representation of behavioral capabilities allow great flexibility and adaptability. The intermediate level of dynamic knowledge representation nicely separates systems dynamics methods (exploiting large data streams from sensing) from AI-methods with predominantly quasi-static knowledge components (for mission planning, situation assessment and behavior decision). Behavioral capabilities are represented on both levels with correspondingly adapted interface parameters and methods. Results will be shown by video for combined radar/vision-based hybrid adaptive cruise control (keeping speed-dependent distance to the vehicle in front) on highways (VaMP) and for mission performance on a network of minor unmarked roads, and cross-country-driving on grass surfaces with avoidance of negative obstacles (ditches). In the last-mentioned application (maybe for the first time) full frame-rate, full image stereo interpretation in this complex environment has been achieved integrating special US-hardware (Pyramid Vision Technology ‘Acadia’) into the distributed COTS-PC-system used for EMS-vision.
