10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: NOTE: DATE CHANGE ** Fundamental Constants and Tests of Theory in Rydberg States of Hydrogen-Like Ions ** NOTE: DATE CHANGE
Comparison of precision frequency measurements to quantum electrodynamics (QED) predictions for Rydberg states of hydrogen-like ions can yield information on values of fundamental constants and test theory. In this talk, simplifications in the theory for Rydberg states that allow a substantial improvement in the accuracy of the predicted levels, will be described. For these states, the fact that the wave function is small near the nucleus results in the finite nuclear size correction being completely negligible. Also, for Rydberg states, the higher-order terms in the QED corrections are relatively smaller than they are for S states, so theoretical expressions with a given number of terms are more accurate. With these improvements, the uncertainty in the predictions is dominated by the uncertainty in the Rydberg constant, the electron-nucleus mass ratio, and the fine-structure constant.

2/18 -- WEDNESDAY

11:00 AM - STATISTICAL ENGINEERING DIVISION SEMINAR: Experimental Design in the Scheduling of Two Unrelated Parallel Processors
Given a group of tasks and two non-identical processors with the ability to complete each task, which tasks should be assigned to which processor to complete the group of tasks in as short amount of time as possible? Processors may be airport runways, shipping trucks, manufacturing lines, computer processors, or surgeons. The tasks may be airplane take-offs and landings, packages to be shipped, products to be built, computer codes to be run, or patients to be operated on. This problem has been formalized in the scheduling literature as the minimization of the makespan (time required to complete all tasks) for two unrelated parallel processors. One possible approach to solving this problem is to simulate the process, consider the computed processing times for all possible assignment schedules (complete enumeration), and select the assignment schedule that produces the minimum makespan. A typical implementation of the complete enumeration approach is to calculate the makespan for each assignment schedule one by one, noting the minimum makespan and associated assignment schedule observed thus far. This talk discusses the benefit realized by implementing the complete enumeration approach using a 2k full factorial experimental design framework, as illustrated by a printed circuit board assembly case study. Also explored is the possibility of employing the 2k - p fractional factorial experimental design structure in the solution of the two unrelated parallel processors problem.

2:00 PM - POLYMERS DIVISION SEMINAR: Role of interphase in polymer matrix composites on micro- and nano-scale: Continuum mechanics and polymer physics approach
The control of the performance of polymer composites can be excercised at various length scales. At the macro-scale, part design and manufacturing technology are the principal means of achieving desired structural performance. Properties of the constituents, their content and spatial arrangement and the 3D-interphase phenomena are the main variables at the micro-scale. Most of current applications of composites in the aerospace structures, aircrafts, cars, boats and sporting goods are only considering this 2-level composite design. It seems possible to consider an additional length scale in the design of future polymer composites to achieve composite structures capable of signaling their integrity status and capable of self repair locally by taking advantage of the nano-scale materials design. This approach simulates, to some extent, multiscale structure of biocomposites such as wood, bones, shells or other cytoskeletons. The hierarchical structure and multifunctional performance of biocomposites is controlled at the various length-scale interfaces between the individual structural levels. Unlike at the micro- and macro- scales, where the 3D-interphases existing between the individual components or phases are considered continuous, at the nano-scale, both the 2D-interface and the 3D-interphase phenomena must be considered at the length scales corresponding to the dimensions of individual molecules. Questions like "Does the inclusion shape matter on the nanoscale?" or "Will nano-composites ever reach the structural properties of micro-composites?" are challenging large number of researchers active in the area of advanced polymer composites. This presentation aims at elucidating some aspects of the principal differences between the role of interface/interphase phenomena as affected by the dimension scale from 10-6 m to 10-9 m. In order to provide experimental background for understanding micro-scale interphase, thickness dependence of elastic moduli of thin organic layers deposited on solid glass surfaces will be discussed. Effects of molecular structure and type of surface interactions on the elastic moduli of these layers will be described. An attempt will be made to correlate the obtained data with the results of the single embedded fiber fragmentation tests. Further, temperature and composition dependeces of elastic moduli of model nanocomposites containing particles of varying shape with smilar specific surface area of approximately 150 m2/g will be interpreted using chain reptation dynamics approach to describe the molecular reinforcing mechanism at the nano-scale and the controlling role of the area of contact between the matrix and the reinforcement. A "hybrid" approach to bridge the micro-scale continuum mechanics models with the nano-scale discrete chain dynamics models will be demonstrated to provide means for transforming mechanical response of a polymer composite accross the individual length scales from nano- to macro-scale

2/19 -- THURSDAY

10:30 AM - CNST ELECTRON PHYSICS GROUP & QUANTUM ELECTRICAL METROLOGY DIVISION SEMINAR: Quantum effects in the conductivity of high-mobility Si MOSFET at ultra-low temperatures
We have measured the conductivity of high-mobility (001) Si metal-oxide-semiconductor field effect transistors over wide ranges of electron densities n=(1.8–15)x10^11 cm^-2, temperatures T=30mK–4.2K, and in-plane magnetic fields B=0–5T. The experimental data have been analyzed using the theory of interaction effects in the conductivity of disordered two-dimensional (2D) systems. The parameters essential for comparison with the theory, such as the intervalley scattering time and valley splitting, have been measured in independent experiments. The observed behavior of the conductivity, including the quasi-linear increase with decreasing T down to ~0.4K and its downturn at lower temperatures, is in agreement with the theory. The values of the Fermi-liquid parameter F_0^\sigma, obtained from the comparison agree with the corresponding values extracted from the analysis of Shubnikov–de Haas oscillations based on the theory of magneto-oscillations in interacting 2D systems.

1:00 PM - BUILDING ENVIRONMENT DIVISION SEMINAR: A New Modeling Methodology for Deposition of Airborne Particulate Matter
Given that people spend most of their time indoors (over 80%), the presence of particles in indoor air is an important air quality issue. Inhalation exposure to airborne particles has been shown to have adverse effects on health. Particle deposition (loss) to surfaces can affect exposure, as deposited particles cannot be inhaled effectively. Several factors affect the rate of deposition such as the flow structure, surface characteristics and air temperature gradient. In this talk, a new analytical model developed for particle deposition onto indoor surfaces will be introduced and discussed. This model predicts deposition to smooth surfaces as a function of particle size, density and turbulent intensity. The developed model has been successfully incorporated into computational software providing an Eulerian approach to model particle distribution for indoor environments. Several examples are given to illustrate application of the model to predict human exposure.

10:30 AM - NIST COLLOQUIUM SERIES: Making Life and Death Decisions in Conditions of Uncertainty: Options in the 2008 Russian-Georgian War
The Russian-Georgian war in August-October 2008 caused about 6000 casualties and displaced more than 130,000 people. All Georgian villages in the territory of South Ossetia were leveled. Overall damage to property is estimated at about $1B. Russian troops temporarily occupied up to a quarter of the Georgian territory, and Russia has unilaterally recognized the independence of Abkhazia and South Ossetia and deployed thousands of new troops on a permanent basis in those territories. Based on even this brief account, there is a widespread notion that on August 7 Georgian President Mikheil Saakashvili made a fatal mistake by ordering Georgian troops to launch an attack on Tskhinvali, on South Ossetian formations, and on Russian 'peace-keeping' troops. Could he have behaved differently, and if so, how differently? What would happen if he had not mobilized his troops? Had he not ordered Georgian troops to fight, would it have been possible to stop the offensive from the North and avoid the war? What would happen if Mr. Saakashvili had decided to wait? * From 2000-2005 Dr. Illarionov was the chief economic adviser of Russian President Vladimir Putin. He also served as Mr. Putin's personal representative on the G-8. He is said to be one of Russia's most forceful and articulate advocates of an open society and democratic capitalism.

ADVANCE NOTICE

2/23/09 11:00 AM - CHEMICAL SCIENCE AND TECHNOLOGY LABORATORY OFFICE SEMINAR: Chemical Science and Technology Laboratory Colloquium
Knowledge of cellular structure and function has advanced in recent years because of progress in biochemistry, molecular biology and microscopy. Advances in fluorescence microscopy due to improved dyes, techniques and equipment has facilitated the viewing and measurement of intimate cellular details. A snippet of data from live and fixed cells in a number of applications using high content imaging and non-laser confocal equipment developed by the investigators will be highlighted. There are pressing needs for advances in fluorescence microscopy to improve the state-of-the-art in terms of both temporal and spatial 3D resolution. For greatest adaptation by the scientific community, these advances should be simple, fast and low in cost. With that in mind, we have recently described a simple and new approach to 2-photon microscopy and a new concept in laserless holography which could acquire all the information in a 3D field in one snapshot and without laser illumination! The new technique in 2-photon microscopy obviates the current need to scan the pulsed laser beam across the sample to excite 2-photon fluorescence on a pixel by pixel basis with the emission recorded by a photomultiplier tube. In our non-scanning approach, 2-photon fluorescence of a full microscope field is captured on the image array of a CCD camera after the whole field is simultaneously excited by a uniformly expanded pulsed laser beam. FINCH is our new laserless holographic technique which can be applied to any wave-based imaging technique and stands for Fresnel Incoherent Correlation Holography. It is much simpler than conventional holography since it is a single beam system where interference to create the hologram occurs from two self-interfering beams which originate from the object under observation. Initial results of macro reflected light and multicolor fluorescence imaging will be shown. The technique has been applied to fluorescence microscopy and is called FINCHSCOPE. The current status of the FINCHSCOPE will be presented. Full development of FINCH promises to simplify many wave-based 3D imaging techniques in addition to microscopy. Furthermore, since off-axis holography can increase resolution beyond the Raleigh optical limit, FINCH could also be a useful platform for super-resolution.

2/25/09 3:00 PM - BIOCHEMICAL SCIENCE DIVISION SEMINAR: Pathogen Ecology: The Fate of Bacillus anthracis in the Environment
Much work has been devoted to the recovery and collection procedures of WMD organisms in atypical "environmental" settings; however, many of these organisms pose different recovery and collection difficulties when sampling is performed in the natural environment. The Air Force Research Laboratory has studied several WMD organisms over the years, and now has branched out into studying select WMD organisms in their natural settings--a term referred to as Pathogenic Ecology. Pathogenic ecology is the study of the set of conditions necessary for the sustainment of a pathogen in the natural environment. This definition assumes that microbes do not become pathogens in isolation but require the correct ecology to express or sustain pathogenicity. Anthrax is endemic around the world (except Antarctica) ,ever present in the natural environment as a quiescent spore between outbreaks, and occasionally, may multiply in certain soil types, and re-emerges in isolated outbreaks. Bacillus anthracis has not become the "perfect" lethal pathogen and created pandemics, in spite of its antiquity and its worldwide distribution. This presentation will cover the field findings, as well as the lessons learned in standing-up their pathogenic ecology program. Findings and lessons learned include: - Paradigm shifts of how organisms behave in laboratory settings versus naturally occurring field settings - The concept of "Pathogenic Ecology" which studies the relationship between the organisms and the environment in which they reside - The role of soil in determining how viable a WMD organism can survive in the environment - Difficulties in obtaining specific organisms, even in the presence of an epidemic - Potential zoonotic involvement and surveillance following a WMD release

3/2/09 10:30 AM - CNST ELECTRON PHYSICS GROUP SEMINAR: DYNAMICAL MEASUREMENTS WITH A NUCLEAR MAGNETIC RESONANCE FORCE MICROSCOPE
Nuclear Magnetic Resonance Force Microscopy (NMRFM) is a technique that combines the fine resolution of scanning probe microscopy with the spin sensitivity of nuclear magnetic resonance (NMR) to yield highly detailed spin information. NMRFM provides resolution that is several orders of magnitude finer than conventional NMR, thus enabling measurements of samples previously inaccessible by conventional NMR, such as thin films and nanostrucstures. In this talk I will discuss the principle behind NMRFM operation and the construction as well as experiments we have performed with our He-3 NMRFM. Room temperature measurements were taken on ammonium sulfate to yield micron scale 1-D images and a spin echo as well as the demonstration of spin nutation. I will also discuss future applications of this instrument toward relaxation measurements of single crystal magnesium diboride at low temperatures as well as other experiments that increase the sensitivity of this technique.

3/6/09 10:30 AM - NIST COLLOQUIUM SERIES: Next Generation Neural Implants
Neurons, once severely damaged, do not repair or regenerate themselves, leaving permanent debilitating deficits for tens of millions of people worldwide. As there's no other solution within sight, implant technology is used to intact tissues and/or replace defective functions, e.g., pacemakers and electronic cochlear implants. However, current implants are far from ideal. They are still bulky, rigid, power hungry, and functionally limited. Some, like retinal implants, require more advanced features, like a large number of electrodes and extreme volume. This talk will review progress on next generation implants, which must be miniature, flexible, and highly functional for better muscular, retinal, cortical and spinal use.
