MEETINGS AT NIST

ITL Seminar Series

RECENT DEVELOPMENTS IN DATA MINING

Usama Fayyad
Senior Researcher,Decision Theory & Adaptive Systems Group, Microsoft Research. Redmond, CA


Monday, March 8, 1999, 10:30AM, Lecture Room A, Administration Building.

Systems for extracting interesting structure from databases, especially large data stores, are becoming a necessity. The existing data access model is clearly hitting its limits. Data Mining methods provide a way to address some of these problems. These methods have their origins in statistics, databases, pattern recognition, learning, visualization, and parallel computing. I'll outline some recent advances towards scaling mining algorithms to large databases, and cover the research challenges and opportunities posed by the problem of extracting models from massive data sets. The talk will particularly focus on the decomposition of classification and clustering algorithms so that they work effectively with a database system back-end.

Biography: Usama Fayyad is a Senior Researcher at Microsoft Research (http://research.microsoft.com/~fayyad). His research interests include scaling data mining algorithms to large databases, learning algorithms, and statistical pattern recognition, especially classification and clustering. He is Editor-in-Chief of the journal Data Mining and Knowledge Discovery.

(NOTE: The location for this seminar has changed since the original announcement.)

ENHANCED BONE CELL RESPONSE WITH SURFACE-IMMOBILIZED PEPTIDES

Geoffrey Moodie
Dept of Molecular Pharmacology and Biotechnology, Brown University. Providence, RI


Thursday, March 11, 1999, 10:30AM, Rm. B165, Bldg 221.

Cells communicate with their extracellular matrix (ECM) by interacting with specific amino acid sequences located within large ECM proteins. Cell-ECM interactions are largely regulated through a family of heterodimeric receptors called integrins. Several of these sequences (peptides) have been characterized and have functional effects similar to the parent protein. In working toward improving biomaterial surfaces for orthopedic and dental applications we have immobilized one such fragment, RGD (argenine-glycine-aspartic acid), to the surface of gold via a gold-thiol linkage. Contact angle and surface plasmon resonance have been used to characterize the resultant peptide layer. Bone cells (osteoblasts) were isolated from neonatal rat calvariae. These cells show 100% greater adhesion to RGD-treated surfaces at 20 minutes, even in the presence of serum proteins. Real-time video imaging shows that surface-immobilized RGD also increases the rate and extent of cell spreading. Alkaline phosphatase, a marker for bone cell maturation, is up regulated on RGD surfaces, as is the mRNA for certain RGD receptors (integrins). Osteoblasts are also observed to form focal adhesions (integrin-mediated signaling clusters) on these surfaces. RGD-coated, but not protein coated, surfaces maintain this bioactivity even after 30 days exposure to ionic media. Experiments performed over a range of surface concentrations of RGD show this effect to be dose-dependent. In vivo pilot studies carried out with a rat femur model showed that RGD coated implants enhanced bone coverage and thickness.

CSTL Colloquium Series

FABRICATION OF SILICON-BASED FIELD EMITTER ARRAYS

Gary McGuire
Director, Materials Center of North Carolina, Research Triangle Park, NC.


Friday, March 12, 1999, 10:30AM, Lecture Room A, Administration Building.

Vacuum microelectronics is a new interdisciplinary field utilizing the mechanism of electron emission into a vacuum. By fabricating arrays of conductive or semiconductive structures that are gated or ungated, a multitude of devices can be formed that utilize cold emission and ballistic transport of electrons from emitting cathodes to appropriate collector electrodes. Vacuum microelctronic devices have potential in a wide range of applications including flat panel displays, high-frequency power sources and amplifiers, radiation-hardened and high temperature electronics and sensors. Field emitter devices have been fabricated utilizing sharpened tips and deposited films; horizontal and vertical structures have been produced; metal and semiconductor tips have been utilized. The relative merits of these various structures will be reviewed along with a history of the technology. MCNC has chosen silicon as the cathode material because of its compatibility with standard CMOS and bipolar technologies. A review will be provided of the status of MCNC's field emitter program. The process technology utilizing orientation dependent and oxidation sharpening of the field emitter tips will be highlighted. Issues concerning the statistical control of the fabrication process, critical in view of the need for reliable large arrays, will be discussed. Integration of low work function coatings into the silicon emitter processing sequence will be presented.

NIST WEB SITE ANNOUNCEMENTS

LEADERSHIP AND MANAGEMENT DEVELOPMENT AT NIST

Last year, the Director of NIST appointed a task group charged to identify and make available an evolving system of leadership and management development and training options suitable for the NIST culture and research environment. A sub-committee of that task group surveyed about 1,000 employees including seniors managers, middle managers, and non-management staff. The results of that survey are presented on the website.

In the coming weeks the website will be expanded to include the final report of last year's task group, and ongoing activities in this area.
