10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: Vortices and persistent currents: Rotating a condensate using photons with orbital angular momentum
I will describe experiments on generating atomic vortex states in a Bose-Einstein condensate (BEC) of sodium atoms by transferring the orbital angular momentum of a photon to an atom in quantized units of h, using a 2-photon stimulated Raman process with Laguerre-Gaussian beams. The process is coherent and can create superpositions of different vortex states, where the relative phase between the states is determined by the relative phases of the optical fields. We use this technique to generate circular flow of a BEC confined in a toroidal shaped trap. We measure that the flow of atoms persists for up to 10 seconds, which we interpret as the first direct evidence of persistent currents in a superfluid Bose gas. Stable flow was only possible in the multiply-connected geometry of the toroidal trap, and was observed for a BEC fraction as small as 15%. We also observed flow with higher angular momentum, and its splitting into singly-charged vortices when the trap topology was changed from multiply- to simply-connected.

10:30 AM - NIST COLLOQUIUM SERIES: From the Mona Lisa to the Space Shuttle -- New Heights in 3D Imaging
In recent years, three-dimensional (3D) imaging systems have come out of research laboratories to find niche markets in fields as diverse as manufacturing, anthropometry, geomatics, space exploration, and cultural heritage. Applications include recent 3D scans of the Mona Lisa, the documentation of an 8000 year old Palaeolithic site, industrial inspection, anthropometry, and the in-orbit inspection of NASA's space shuttle tiles. 3D introduces important new challenges for research: diffraction limited optical systems, the interaction of light with materials, acquisition in harsh environments, and the management of huge amount of information. The key roles played by NRC and NIST in data management and the development of industrial standards will also be discussed.

1:30 PM - CENTER FOR NANOSCALE SCIENCE AND TECHNOLOGY SEMINAR: Biological macromolecules as scaffolding for precisely engineered nanostructures
We are currently developing a system for using biological macromolecules as scaffolding for the construction of nanostructures comprising multiple inorganic nanoparticles. The system utilizes the geometry of the macromolecules to define the three-dimensional arrangement of inorganic particles in the structure. A massively parallel assembly process will be used to provide for the mass production of identical nanostructures. We envision applications to include, for example, (i) construction of small assemblies of metallic nanoparticles to form nanolenses capable of focusing surface plasmons and (ii) the construction of magnetic cellular automata.

10/30/07 2:00 PM - PHYSICAL AND CHEMICAL PROPERTIES DIVISION SEMINAR: Hydrophobic-Hydrophilic Phenomena in Protein Folding and in Protein-Protein Association
An analysis of the solvent induced contributions to the thermodynamic driving forced for protein folding and protein-protein association reveals that, contrary to the common wisdom, Hydrophilic interactions might be more important than Hydrophobic interactions. For fifteen years I have been working on hydrophobic interactions, and I believed, as most people do, that hydrophobic Interactions are the most important contributions to the driving forces for biochemical processes. Now, after critically examined the data on the various contributions to the driving forces for protein folding, and protein-protein interactions, I reached the conclusion that the Hydrophilic interactions, rather hydrophobic interactions are the more important in biochemical processes. Examples on the role of Hydrophilic interactions on solubility, protein association and molecular recognition will be presented.

10/30/07 6:30 PM - AMERICAN SOCIETY FOR QUALITY SSIG AND SOCIETY FOR SOFTWARE QUALITY: My Life with Bugs, or, Why I Believe in Combinatorial Testing
This presentation describes the benefits of combinatorial testing. Trying all combinations of inputs or program settings is impossible for most programs. However research shows that trying all pairs, all triples, all 4-way, up to 6-way combinations of parameters catches most bugs. Theoretically a relatively small number of tests can exercise all k-way combinations since a single execution exercises on the order of p^k k-way combinations, where p is the number of parameters. Recent algorithms have been able to quickly find a packing of all k-way combinations into a relatively small number of tests.

11/1/07 1:30 PM - INFORMATION ACCESS DIVISION SEMINAR: Virtual Reality Research in Biomedical and Industrial Applications
In this presentation, the speaker will talk about Virtual Reality Research applied to the fields of biomedical engineering, manufacturing, clinical and industrial applications. Software tools have been developed for computer-aided surgical planning, guiding, and navigation in oral/maxillofacial, dental, and spine regions. A portable navigation grading system was constructed to train future orthopedic surgeons. A self-developed tracking system is used to achieve the goal of surgical planning with an accuracy of 0.19mm RMS within the tracking range of 0.6m~1.0m. The aim of these tools is to create a mass customization product to be used with different patients and different treatments but in the same syndrome. Several medical procedures have benefited from the current research, such as maxillofacial reconstruction after tumor removal, model navigation surgery, 3D cephalometry, aesthetic evaluation, dental implantation, and pedicle screw implantation, etc. A virtual reality system has recently been built to be applied to occupational therapy and rehabilitation for people who suffer from Parkinson's disease, Alzheimer's disease, and stroke, and children who suffer from movement battery difficulty. In the industrial arena, a specific virtual design studio was built for a motorcycle manufacturing company to speed up their workflow from design to manufacturing. Bio: Jing-Jing Fang received her BS and MSc in applied mathematics in Taiwan, 1984. She then became a lecturer in the Department of Accounting and Statistics at Tainan Women College, and soon moved to the Department Mechanical Engineering at the National Cheng Kung University. In 1993, she was sponsored by the government to pursue her PhD in Mechanical and Chemical Engineering in Heriot-Watt University, Britain which she achieved in 1996. Currently, as Associate Professor in the Department of Mechanical Engineering at the National Cheng Kung University, Taiwan, she leads her research team working in the areas of digital human modeling, anthropometry, 3D garment design, pattern generating, image-based surgical planning, surgical navigation, and recently, occupational therapy and rehabilitation. Her work in clinical areas has benefited over 80 patients in oral/maxillofacial and spinal surgeries. Her research interests are geometric modeling, computational geometry, object-oriented design, e-Learning, and virtual reality applications. During the last eleven years, she has published nearly one hundred papers and filed for ten innovation patents. She has regularly obtained research funding from both government and from industry.
