10:45 AM - NIST SEMINAR: Oxygen Phonon Anomalies in Strongly Correlated Perovskite Oxides
Remarkable electronic properties of many perovskite oxides such as high temperature superconductivity and colossal magnetoresistance (CMR) are of both practical and fundamental interest. Oxygen vibrations in these materials are strongly coupled to electronic degrees of freedom as evidenced by a number of experimental and theoretical results. Thus detailed measurements of phonons with oxygen character can be used as a sensitive probe of electronic states. Results of several neutron scattering studies of phonon dispersions at different temperatures in YBa2Cu3O7, Ba0.6K0.4BiO3, La1.69Sr0.31NiO4, and La0.7Sr0.3MnO3 will be presented. Effects of superconductivity, charge inhomogeneities including stripes, and the CMR transition on the oxygen vibrations will be discussed.

2:00 PM - INFORMATION TECHNOLOGY LABORATORY SEMINAR: Free and Open Source Software (FOSS) Uses in the Department of Defense
Dr. Bollinger will brief interested NIST staff on the results of a new survey completed by MITRE for the Defense Information Systems Agency (DISA) on the number and types of FOSS applications within the Department of Defense. The main conclusion of the analysis was that FOSS software plays a more critical role in the DoD than has generally been recognized. FOSS applications are most important in four broad areas: Infrastructure Support, Software Development, Security, and Research. Dr. Bollinger encourages critics and skeptics about FOSS to pepper him with tough questions!

1/16 -- THURSDAY

10:45 AM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Pr0.6Ca0.4MnO3: From Low-Temperature Ordering to the Effects of Substrate-Induced Strain
Renewed interest in the perovskite manganites followed the initial report of a colossal magnetoresistance effect in a La0.67Ca0.33MnO3 film. Yet, this effect is just one of the many fascinating phenomena exhibited by these materials. For example in bulk Pr0.6Ca0.4MnO3, the ground state properties are determined by a balancing of several degrees of freedom that results in novel types of low-temperature ordering: a complicated charge and orbital ordering with associated lattice distortions occurs below a temperature of ~245 K, and at lower temperatures, magnetic ordering consisting of ferromagnetic zigzags-antiferromagnetically coupled-sets in. In Pr0.6Ca0.4MnO3 films, substrate-induced strain can also affect the balancing of the various degrees of freedom, and can have significant effects on both the structure and low-temperature ordering. In this talk, I will describe studies of Pr0.6Ca0.4MnO3-in both bulk and film form-which were carried out using several x-ray scattering techniques.

1/21/03 12:00 PM - OFFICE OF INTERNATIONAL AND ACADEMIC AFFAIRS SEMINAR: NRC Postdoctoral Research Associates Monthly "No-Host" Brown Bag Lunch
Dr. Jack Hsia, NIST NRC Postdoctoral Research Associateships Program Representative, Office of International and Academic Affairs, Division 109, is sponsoring monthly "no-host" brown bag lunch gatherings for NRC postdoctoral research associates. All postdocs are invited, from those newly arrived and those who may be nearing the end of their tenure at NIST. The purpose of these lunches is for NRC postdocs at NIST to get to know each other and establish a network. This will be your time and place to meet with each other. The next no-host brown bag lunch is scheduled for January 21, 2003, 12:00pm-1:00pm, in the Division 109 conference room, building 222, room B212. Future no-host brown bag lunches are scheduled for February 18, 2003, and March 18, 2003, same location as stated above. These no-host brown bag lunches are scheduled for the third Tuesday of each month through the end of 2003.

1/29/03 10:30 AM - INFORMATION TECHNOLOGY LABORATORY SEMINAR: Fuzzy Logic, or How I Learned to Stopy Worrying and Love Partial Set Membership
Fuzzy logic allows inference and computations based on partial membership of entities in given sets. In practice, it allows machines to deal cleanly and robustly with natural imprecision, and has spawned applications in a variety of areas. It has facilitated programming of neural networks, decision aids, expert systems, and controllers. In modeling, it can improve on traditional approaches, as it lends itself to traditional coding methods with less code complexity As an example, the speaker will use an ultimately neuro-fuzzy implementation of a high-order differential-equation-based muscle force estimation model that she is developing. Some background on fuzzy logic and its applications will be given to demonstrate the benefits of using it, and potential future uses of fuzzy logic will be discussed. Bio: Amy J. O'Brien (aobrien@dsrnet.com) is a systems engineer with Digital System Resources, Inc. in Fairfax, VA and is finishing her PhD in Electrical Engineering at George Washington University. Her dissertation involves control-theoretic systems modeling, soft computing, and biomedical engineering. Her current research involves developing an ultimately neuro-fuzzy implementation of a high-order differential-equation-based muscle force estimation model. She has publications related to her research and to a powerful generalized fuzzy inference engine she developed to support it. She regularly presents fuzzy logic tutorials.
