MEETINGS AT NIST

NEXT GENERATION DESIGN ENVIRONMENTS

Bill Eckert
NASA.

Phil Milstead
NASA

John Malone, NASA

Monday, February 8, 1999, 9:00AM, - Monday, February 8, 1999 Rm. A108, Bldg 220.

NASA has established a new strategic goal to provide advanced development tools, process and products to increase design confidence, and reduce the design cycle time for aircraft and space vehicles by 50% in 10 years and by 75% in 25 years. The goal uses commercial aircraft as a baseline, but, with varying results, the products easily apply to defense craft, experimental craft, and vehicles for space access and transportation. Many of the products generated in this goal are expected to help in various other design and manufacturing environments. NASA is seeking to collaborate with other Federal agencies to achieve what is quickly becoming a National Goal. This talk will include NASA's current roadmap for achieving the goal and is presented as part of the opening remarks in discussions to establish active collaboration between NASA and NIST.

THE EFFECT OF A SINGLE ADSORBED ATOM ON THE LOCAL ELECTRONIC STRUCTURE AT SEMICONDUCTOR SURFACES: STM-PHOTOVOLTAGE IMAGING

Dr. Gaddi Haase
Department of Chemical Physics, Weizmann Institute for Science. Rehovot, Israel


Wednesday, February 10, 1999, 10:30AM, Rm.A-322, Bldg.222.

For the first time, atomically resolved, local surface photovoltage imaging through scanning tunneling microscopy (STM) was used to detect surfaces states created by single alkali metal adatoms and single defects on GaAs (11), Si (100) 2x1 and Si (111) 7x7 surfaces. We took advantage of the fact that the electric field produced by the STM tip penetrates the surface to study local Fermi-leveling pinning. This work was aimed to help understand changes in thermal and photo-reactivity of semiconductor surfaces in the vicinity of single adsorbates and defects.

Polymers Division Distinguished Lecturer Series

SYNCHROTRON RADIATION STUDIES OF LIQUID POLYMER FILMS

Dr. Sunil K. Sinha
Advanced Photon Source, Argonne National Laboratory. Argonne, IL


Thursday, February 11, 1999, 11:00AM, Rm. B245, Bldg. 224.

X-Ray reflectivity and off-specular diffuse scattering have become popular techniques for characterizing structure and fluctuations in thin liquid films of polymers and other forms of soft condensed matter. We shall review these techniques and discuss a variety of recent experimental results such as studies of capillary wave fluctuations of liquid polymer films and the effects of finite thickness, the static and relaxational effects associated with conformal height fluctuations of the free surface and the substrate, as well as recent studies on dewetting and island formation and their effect on capillary waves.

Optical Technology Division Seminar

BIOLOGICAL APPLICATIONS OF MULTIPHOTON SCANNING NEAR FIELD OPTICAL MICROSCOPY

Vinod Subramaniam
Department of Molecular Biology, Max Planck Institute for Biophysical Chemistry. Gottingen, Germany


Thursday, February 18, 1999, 10:30AM, Rm. B165, Bldg 221.

We have implemented multiphoton excitation with continuous-wave (CW) and picosecond pulsed lasers in our scanning near-field optical microscope (SNOM). With a CW laser operating at 647 nm we can generate background-free images of the important near-UV absorbing DNA dyes Ethidium Bromide, DAPI, and Hoechst 33342 bound to polytene chromosomes and cell nuclei. Using a picosecond pulsed 1064 nm laser we can simultaneously image two-photon excited visible dyes and three-photon excited near-UV dyes in a crosstalk-free manner. Multiphoton excitation yields enhanced axial resolutions and improved photobleaching characteristics compared to one-photon excitation for our samples.

CSTL Colloquium Series

OXIDATIVE STRESS AND AGING

Richard Cutler
President and Scientific Director, Human Longevity Sciences. Phoenix, AZ


Thursday, February 18, 1999, 10:30AM, Lecture Room A, Administration Building.

Metabolism, like other aspects of life, involves tradeoffs. Scientists now know that oxidant by-products from normal metabolism and exogenous sources cause damage to DNA, protein and lipid (fat). This damage, known as Oxidative Stress, has been implicated in a range of diseases including cancer, arteriosclerosis, neurodegenerative diseases such as Parkinson's and Alzheimer's, and aging.

Antioxidant supplements protect your body from oxidative stress damage, but how does one know they are working. To answer this question, a new diagnostic field has emerged. Oxidative Stress Profiling analyzes key markers within your body to determine an individual's level of oxidative stress and level of antioxidant protection.

To learn about this exciting field, Dr. Richard G. Cutler will discuss the current measurement technologies used for analysis and outline the importance of monitoring one's level of oxidative stress.

Advance Notice NIST Colloquium Series

USING SUPERCOMPUTERS TO DESIGN AND MODEL NOVEL MATERIALS

Professor Steven R. Richardson
Materials Science Research Center, Howard University.


Friday, February 19, 1999, 10:30AM, Green Auditorium, Administration Building.

Everyone is familiar with the marvelous computer simulations being used in the movies, like scenes of the Titanic sailing off from Liverpool, intergalactic space travel, and toys, ants, and pigs with anthropomorphic behavior. Professor Richardson will discuss how the power of modern supercomputers, coupled with recent advances in computational materials science and theoretical condensed matter physics, is enabling us to design and study novel materials -- new plastics, new composite materials, and new drugs -- and then model their behavior and test their performance under simulated conditions. As an example, he will discuss recent calculations on the structural properties of the energetic material, solid cubane, and a first-principles study of the high pressure phases of zinc.

AI PLANNING: A NEW APPROACH

Dana Nau
Prof., Computer Sciences & Dir., Computer-Integrated Manufacturing Laboratory, Univ. of Maryland.


Monday, February 22, 1999, 11:00AM, Lecture Room D, Administration Building.

The Simple Hierarchical Ordered Planner (SHOP) is among the fastest and most versatile systems for computational planning (often called artificial intelligence planning). In fact, it is proving to be orders of magnitude faster than other general planning methods. It is the outgrowth of work in planning that has also been applied to manufacturing planning and even incorporated in a successful electronic bridge-playing program that featured in stories in the New York Times and Washington Post. This talk summarizes recent experiences with the technique, as well as the possible future uses.

Biography: Dana Nau ( http://www.cs.umd.edu/users/nau/ ) is professor of Computer Science and Director of the Computer-Integrated Manufacturing Laboratory at the University of Maryland. His research interests include artificial intelligence in planning and searching and computer-integrated design and manufacturing. He received his Ph.D. from Duke University in 1979 and now has more than 200 technical publications. An NSF Graduate Fellow and later an NSF Presidential Young Investigator, he has also been awarded the ISR Outstanding Systems Engineering Faculty award at the University of Maryland, and is a Fellow of the American Association for Artificial Intelligence (AAAI).
