4/19 -- WEDNESDAY

10:30 AM - ELECTRON AND OPTICAL PHYSICS DIVISION SEMINAR: Complex Matter-Antimatter Structures
The first rigorous calculation demonstrating positron binding to a non-hydrogenic atom was presented in 1997/1998 for lithium. Subsequent calculations have show positron and positronium binding to many other atoms. Analysis of these systems provides detailed information on matter-antimatter interactions and insight into the dynamics of the electron-positron annihilation in materials.

4/20 -- THURSDAY

10:30 AM - ELECTRON AND OPTICAL PHYSICS DIVISION SEMINAR: The STM as a Magnetic Microscope
Light is emitted when an STM scans a metal surface. If the metal is magnetic the light will be circularly polarized with a polarization that is related to the magnetization of the metal. This implies the possibility of a magnetic microscope with exceptional resolution. We will discuss the physics of such a microscope.

4/21 -- FRIDAY

10:30 AM - INFORMATION TECHNOLOGY LABORATORY SEMINAR: The Systems Engineering Process Activities (SEPA) Methodology and Tool Suite
The SEPA methodology and its associated tool suite are described. SEPA provides a documented formal method for the engineering of large, complex systems. It does this by embedding the software or system development process in a larger knowledge engineering framework, resulting in better traceability of code to domain requirements, individual stakeholders, and implementation considerations. It also facilitates a smooth engineering process, documentation of decisions and requirement changes, and coordination of team efforts. Examples of its application are discussed. Bio: Suzanne Barber's current research centers on (1) formal software engineering methods and tools; and (2) distributed, autonomous agent-based systems. Dr. Barber received her Ph.D. in Electrical Engineering from the University of Texas, Arlington, following her BS in Engineering Science from Trinity University. She began her career at the Robotics Institute (Carnegie Mellon), working on languages and interfaces for automated robotic assembly, and later joined the Automation and Robotics Research Institute (UT, Arlington) where her research addressed knowledge-based representations and planning systems for manufacturing applications. As a researcher, she has worked with a variety of government agencies (e.g. NIST, NSF, DARPA, NIH, ONR) and companies (e.g. GM, TI, H-P). She has published nearly 100 articles in refereed conference proceedings and journals and 4 book chapters, and she holds copyrights for software development, knowledge engineering, and simulation environments. She is the recipient of multiple awards for both her teaching and her research, and is active in professional societies.

ADVANCE NOTICE

4/25/00 10:30 AM - NIST CHAPTER SIGMA XI SEMINAR: SIGMA XI COLLOQUIUM SERIES: Cholesterol and Coronary Artery Disease
Cholesterol deposition in the walls of blood vessels begins a complex pathological process called atherosclerosis. Atherosclerosis can eventually lead to blockage of the vessels usually by triggering a blood clot to form. When this process occurs in a coronary artery, the blockage can cause a heart attack. White blood cells (macrophages) respond to the buildup of vessel wall cholesterol. I will discuss mechanisms for cholesterol deposition in arteries and how macrophages function during development of atherosclerotic lesions

4/18 -- TUESDAY

3:00 PM - PROPRIETY AND PROPERTY: INTERNET IN CONFLICT
It has become apparent that without adequate protection the intellectual property of an organization can be easily lost or corrupted. Critical operational functions can be compromised and brand integrity can be threatened. Protecting an enterprise that employs automated information systems at any level requires understanding every level of the "threat" to the information infrastructure including; mistake, misadventure, mischief, malice and malevolence. An additional, and growing, element of the threat derives from a fundamental conflict about the nature and extent of personal property rights in the network. Recent attention in the media has brought hacking threats into sharp focus, at the individual enterprise level. Little attention has been paid to the critical infra-structure threats that result from poor policy and process in the enterprise, or to the public policy that might address the problem of a well protected enterprise suffering information system attack as the result if the poor practices of an interconnected partner. Mr. Herskowitz will discuss the character of each of these threats and recent experience in e-business. He will outline the public policy issues as well as system architectural issues and look briefly at the impact of liability/loss insurance policies on the evolution of a secure national information infrastructure.

MEMORANDUM TO NIST PERSONNEL FROM ENVIRONMENTAL SERVICES
In the interests of more properly handling and disposing of waste paper materials at NIST, and of more effectively contributing to the preservation of the environment, a more aggressive program is being enacted to place color-coded and clearly labeled containers throughout the facilities to collect the different kinds of waste paper. This program will not work without the assistance of all NIST personnel. Please help us make the program successful by disposing of waste paper materials and trash in the proper containers as follows: white paper only (typing or copy paper) in the small grey rectangular cans or the large white round containers; office mix, co-mingled paper in the blue rectangular cans; waste and lunch in the brown and grey round office cans, the burgundy square containers, or the yellow-top round containers; and aluminum cans only in the green rectangular containers. Any questions regarding the program should be directed to the Environmental Services Group.
