10:30 AM - CNST ELECTRON PHYSICS GROUP SEMINAR: Slow-moving atoms and fast-moving particles: Recent results in erbium laser cooling and particle-tracking microscopy
In this talk, I will present the latest results from two research projects in CNST. In the first part, I will discuss new methods for bringing erbium atoms to ultracold temperatures by exploiting the unique laser-cooling properties of this strongly magnetic rare-earth element. The capability to cool, trap and manipulate erbium has applications for developing nanoscale optical devices and may provide access to new regimes in the study of magnetically interacting quantum gases. In the second part, I will discuss a recent breakthrough in tracking the motion of freely diffusing (solution-phase) particles using optical microscopy. A major stumbling block in achieving real-time control of individual molecules or nanoparticles is the difficulty of quickly and accurately extracting accurate position information from a CCD image. We recently developed a new computational method for extracting such information, capable of localizing particles to a few nanometers through a fast and flexible algorithm.

1:30 PM - CNST NANOFABRICATION RESEARCH GROUP SEMINAR: Vision-Based Control via A Lyapunov-Based Approach
Recent advances in visual sensing hardware, image processing/interpretation technology, and computational capability generate a golden opportunity to do real-time vision-based feedback control. This talk will describe research work on vision-based control that is obtained by exploiting a combination of multi-image photogrammetry, homography techniques, a quaternion parameterization, and Lyapunov-based nonlinear and adaptive control methods. Multi-image photogrammetry will be described as it relates to developing a measurable translation and rotation error system (via a homography decomposition) in both Euclidean and quaternion representations. New visual servo tracking control results will be described for a camera system moving with unconstrained motion. The desired trajectory to be tracked is represented by a sequence of images (e.g., a video), which can be taken online or offline by a camera. This control scheme is singularity-free and can compensate for the unknown depth information in visual feedback while achieving the asymptotic tracking results. The proposed method has been verified in a hardware-in-the-loop experimental system for simulation and test of autonomous vehicles. Vision-based control methods motivated by some open issues will also be briefly presented.

10:30 AM - ATOMIC PHYSICS DIVISION SEMINAR: Vibrational dependence of collisional and field-induced interactions of cold molecules
Controllable dipole-dipole interaction between polar molecules in an optical trap lies at the heart of many proposals to exploit entanglement as an essential resource for strongly correlated many-body states and quantum information processing. Even though polar molecules interact at large separations via dipole-dipole interaction, at shorter distances Van der Waals forces will prevail. I study both vibrationally dependent collisional and dipole-dipole interaction between cold polar molecules and with their constituent atoms. The collisional interaction coefficients are obtained by integrating the product of the dynamic polarizabilities over imaginary frequencies. This data can be used to estimate limits on the collisional lifetime of molecules in optical traps and find microscopic mechanisms by which the losses occur. The ultimate goal is to find optimal experimental conditions to diminish these collisional losses. Holding molecules in an optical lattice can prevent them from collisions. It will be helpful to understand how lattice fields and geometry will influence molecular motion, what are the ac Stark shifts of various vibrational levels due to an optical lattice. I will analyze the vibrational dependence of the ac Stark shifts of the polar RbCs and KRb and homonuclear Sr2 molecules in optical lattices.

7:00 PM - ASQ SOFTWARE SPECIAL INTEREST GROUP, SOCIETY FOR SOFTWARE QUALITY (SSQ), AND IEEE COMPUTER SOCIETY: SQA Sojourn: Lessons Learned from Six Appraisals
David Letterman has his Top Tens, but so does Lenny with his "Lenny-isms." Based on 6 successful assessments/appraisals, he gleaned his lessons learned from 3 distinct industries: telecommunications, financial and the military. Though these organizations are totally different in culture, when it comes to process improvements, there are quite a lot of similarities. Lenny takes a light-hearted approach in turning a rather dry topic into something that one would find more entertaining but also more memorable. Lessons learned should not be lessons forgotten! Lenny Eng is a graduate of Polytechnic Institute of Brooklyn with a Math degree and Sacred Heart University with a MBA, Lenny retired from Bell Labs after 20 years with AT&T. During those years, most of his career was invested in the IT field, spanning from Project Management to deployment. In his last two years, he was heading the first SQA group in the Labs that successfully passed CMM/CMMI Level 2 and 3. In total, he and his groups have passed 6 of 6 assessments/appraisals among telecommunications, financial and military industries. Companies he worked for and consulted with are: AT&T, Citi, DoD, Lucent, Pershing and Wolters Kluwer. He has trained and mentored over 100 SQA engineers. Currently he is consulting with Ft. Monmouth in their pursuit to CMMI Level 3. He was a member of the ASQ from 2000 – 2006, and is currently the Program Co-chair of the NJ SPIN Chapter. He is a video and audiophile and an avid investor. There is no cost to attend, but please register on-line at http://www.asq509.org/ht/d/DoSurvey/i/26913 by noon Friday, March 21st, 2008. Pizza and soda will be served at 6:30 PM.

3/26 -- WEDNESDAY

10:45 AM - NIST CENTER FOR NEUTRON RESEARCH SEMINAR: Proteins in Deep Sea Environment, a Combined Approach by Computer Simulation and Neutron Scattering
The adaptation to extreme environmental conditions of living organisms is one of the challenging areas in molecular biology. In the last decades particular interest has been devoted to organisms which populate the deep-sea near hydrothermal chimneys, where the temperature can change over small distances from 4°C up to ~100°C, and pressure usually reaches values of around 100 MPa. Here the speaker will present a study of the anti-association factor 6 (IF6) from the Archaeon Methanococcus Jannaschii, which lives at 2600m under sea-level at temperatures of around 80°C. This protein limits the rate of translation of DNA and has been proven to be sensitive to external stimuli and to the global status of the cell. It plays thus a fundamental role for the life of these bacteria. Very recent results from neutron scattering and molecular dynamics simulation on the influence of extreme conditions - pressures up to 1kbar and high temperatures - on the structure and dynamics of IF6, are used to compare the variants produced by Methanoccoccus Jannaschii and by Saccharomyces cerevisiae (Baker yeast), which lives under normal conditions. Quasielastic neutron scattering experiments have been undertaken to show that the dynamical behavior of both proteins in their natural and reciprocal extreme conditions is affected. We will interpret the dynamics of IF6 in the frame of the fractional Brownian dynamics (fBD) model, which has been proven to describe the internal dynamics of proteins very well over a large range of time scales from sub-nanoseconds to seconds. Moreover, we will show how the small structural differences between the two homologous proteins affect the global response of the proteins to their environmental conditions. These results will be used to discuss a new approach to studies on environmental effects and their relation to evolutionary adaptation of proteins.

3/27 -- THURSDAY

1:30 PM - STATISTICAL ENGINEERING DIVISION SEMINAR: Statistical Models for Cell Populations
The ability to collect large numbers of microphotographs of cell populations, especially those that are grown in culture, for the purpose of characterizing them quantitatively, poses multiple challenges in areas of digital image analysis and statistical modeling. Such characterization depends on the cellular features that are stained for imaging, and on the modality of microscopy that is employed; and it includes not only the distribution of cell size, shape, and orientation relative to the substrate, but also the pattern of the cells' spatial arrangement relative to one another. Since identifying and delineating cells is a typical first step in this endeavor, we begin by reviewing some of the approaches that we believe are most promising for this purpose. In particular, we emphasize the power of contextual approaches to this task. We suggest that deformable templates are useful to characterize cell shape, not only owing to their intrinsic flexibility, but also because they involve parsimonious, parametric representations that lend themselves to calibration to empirical data using conventional statistical methods. In addition, deformable templates can serve as a useful building block in models for cell motion. To describe the patterns of interaction between cells that are captured in still microphotographs, we use the theory of stochastic spatial point processes, and illustrate the use of corresponding descriptive statistical tools, as well as parametric models that can be fitted to data, either for single populations, or for multiple populations that co-exist in the same culture, and that summarize those interactions.

10:30 AM - NIST COLLOQUIUM SERIES: From Flapping Birds to Space Telescopes: The Modern Science of Origami
The last decade of this past century has been witness to a revolution in the development of mathematical techniques to origami, the centuries-old Japanese art of paper-folding. Geometric concepts have led to the solution of a broad class of origami folding problems – specifically, the problem of efficiently folding a shape with an arbitrary number and arrangement of flaps. This has enabled origami designs of mind-blowing complexity and realism, some of which you'll see. As often happens, theory developed for its own sake has led to some surprising practical applications. The algorithms and theorems of origami design have shed light on long-standing mathematical questions and have solved practical engineering problems, e.g. safer airbags, Brobdingnagian space telescopes, and more.

3/31/08 10:30 AM - CNST NANOFABRICATION RESEARCH GROUP SEMINAR: Nanostructured Origami: Stress-Engineering of Nanopatterned Membranes to Produce 3D Structures
Folding nanopatterned membranes at arbitrary angles, like origami, allows one to manufacture 3D nanoscale systems. One challenge with this approach is to achieve very small fold radii for tight 3D packing. Stress induced on a thin membrane by helium ion implantation will fold the membrane to a one-micron radius. Incident ion energy and fluence determine the fold angle and direction, and are easily controllable. One application of stress folding is a chemical sensor. Built from a membrane as a 3D micro-switch, the stress that develops in a reactive polymer bends the switch closed. Thus, it consumes little power and responds to target gases with more than a million-fold electrical resistance change. Other 3D membrane architectures may require accurate feature-alignment. This is solved by patterning membranes with magnetic material so they attract in self-alignment when folded together. These advances open the way for future applications to optical devices, for example, artificial dielectrics such as photonic crystals and more general non-periodic metamaterials, which are formed by combining new optical exposure techniques with membrane folding.

4/3/08 10:30 AM - CNST NANOTECHNOLOGY SEMINAR SERIES: Imaging ultrafast dynamics with electron microscopy: recent advances, challenges and opportunities
Miniaturization of electronic devices with atomic-scale active components is a great technological undertaking and presents a major challenge in metrology. To understand the underlying physics and behavior at the molecular level, which by the very definition is not a static but essentially dynamic process, our group is developing an ultrafast electron microscope (UEM). This methodology combines extreme spatial and temporal resolutions, which allows for the simultaneous characterization of spatiotemporal properties at relevant scales. The versatility of the UEM technology and its applications in electronics, photonics and biotechnology will be illustrated with two distinct examples. The first is the "conventional" pump-probe imaging of ultrafast dynamics during a phase transition in vanadium dioxide, and the second is the direct visualization of a laser controlled reversible transformation in molecular crystals.

4/9/08 10:30 AM - CERAMICS DIVISION SEMINAR: Molecular-Based Design of Materials: The Quest for Super Infrastructure Materials
Two recent events make it possible for revolutionary improvements in construction materials to occur. The first is the growing development and use of Molecular-Based Predictive Rheology. Using ab initio (Quantum Mechanics) and molecular dynamics simulations, the rheologic properties of a material can now be predicted with increasing accuracy based on the atomic and molecular structure of the material. Molecular-Based Predictive Rheology not only provides the ability to predict how a material responds to loads before the material in synthesized, it also provides in-depth insight into the interactions between atoms and molecules that determine this response. Thus it allows for the intelligent design of materials at the molecular level to achieve desired material behavior. The second event is the discovery of carbon nanotubes. Carbon nanotubes are very small, with diameters that range up to a few tens of nanometers, or on the order of a 1/thousandth the diameter of a human hair. They have been grown to lengths of several inches, and researchers are attempting to grow them still longer. They have unprecedented properties as the basis for construction materials. These include tensile strengths to 15.5 million psi, which is about 150-times that of high-strength steel, stiffness (Young's modulus) of 150 million psi, which is about 5-times that of steel, and densities that range from 1/6 to 1/3 that of steel. They have strength-to-weight ratios that range from about 450 to 900 times that of steel. Three recently-inaugurated U.S. Army Engineer Research and Development Center research programs seek to take advantage of these two events to change the paradigm of construction material development. The first two of these research programs are basic research programs that are further developing the science and tools of Molecular-Based Predictive Rheology, and then are using these tools to understand some of the phenomena relating the molecular make-up of carbon nanotube-based constructs to their rheologic properties. The third program is an applied research program that will use this understanding, and the predictive methods to design carbon nanotube-based filaments, membranes, and coatings to Technology Readiness Level 4 (TRL-4) that have tensile strengths of 1-million psi, with associated densities of about 1/5 that of steel. If successful, the developed materials will have about twice the strength-to-weight ratio of Kevlar, and about 5-times the tensile strength of very-high strength (4340 alloy) steel. These goals are to be met by 2010. At that time these laboratory materials may turn out to be prohibitively expensive, but then research will begin on how to make these materials cheaper. This talk will discuss some of the research associated with these programs.

4/18/08 1:30 PM - CNST NANOFABRICATION RESEARCH GROUP SEMINAR: Cavity QED with Charged Quantum Dots
We report on nanodevices that for the first time allow for charge tuning of single InAs quantum dots located near the field maximum of high quality micropillar cavities. Through the innovation of a novel trench style cavity design, we are able to embed doped layers for electrical gating within a microcavity and obtain Q values greater than 50,000. Using these devices, we demonstrate record high single photon count rates with a capture efficiency of 38{\%} and a Purcell effect up to 8. We also show high frequency polarization modulation of single photons enabled by Stark shift tuning a charged quantum dot between two polarization modes of a slightly elliptical micropillar with frequencies up to 100 KHz. Furthermore, we demonstrate a charge tunable quantum dot coupled to a micropillar cavity mode, which is an important step in quantum communication protocols involving trapped single electrons or holes. This type of device enables a quick, non-destructive measurement of the spin state of the trapped charge.

5/1/08 10:30 AM - CNST NANOTECHNOLOGY SEMINAR SERIES: The bright future of nanophotonics: recent advances and challenges
Nanophotonics in which light is manipulated at subwavelength scales is emerging as one the most exciting and potentially useful areas of physical optics. I will highlight recent research in my group aimed at a new class of light-sources in which the near field and the far-field properties are fundamentally altered by means of plasmonic nanostructures and metamaterials monolithically integrated on the laser facets. As a platform to demonstrate these new beam shaping concepts, such as reduction of beam divergence, nanospot light concentration, super-focusing and polarization control, we have used mid-infrared and near-IR lasers but these techniques are broadly applicable to all solid-state lasers. I will also discuss a novel technique called nanoskiving that combines photolithography, thin-film metal deposition, and thin-film sectioning, and demonstrate its capabilities in the realization of metallic nanowires with engineered plasmon resonances and frequency selective surfaces.

5/16/08 1:30 PM - CENTER FOR NANOSCALE SCIENCE AND TECHNOLOGY SEMINAR: Spin Wave Beams, Precessing Vortices, and Localized Standing Waves in Single Layer Nanocontacts
The recently discovered spin transfer effect enables the application of localized torques in magnetic thin film nanostructures. In the point contact geometry, this effect can result in large amplitude spin wave generation. The well studied Slonczewski model of spin torque in trilayer nanostructures is the Landau-Lifshitz equation modified with a local spin torque term. In this talk, a non-local model of point contacts in single layer thin magnetic films is presented and studied numerically in two spatial dimensions. Here, the spin torque term in the Landau-Lifshitz equation is non-local and is due to spin diffusion effects. A variety of quasi-periodic mode solutions to this equation are found including localized standing waves, vortex spiral waves, and a weakly diffracting collimated beam of spin waves, the direction of which can be steered by changing the direction of an applied magnetic field. The spin wave beam appears to be the nonlinear hybridization of the vortex spiral waves and the localized standing wave. Mode selection is explained using linear spin wave theory.
