SHREC12 Track: Generic 3D Shape Retrieval

May 13, 2012
Author(s)
Bo Li, Afzal A. Godil
Generic 3D shape retrieval is a fundamental research area in the field of content-based 3D model retrieval. The aim of this track is to measure and compare the performance of generic 3D shape retrieval methods implemented by different participants over the

SHREC12 Track: Sketch-Based 3D Shape Retrieval

May 13, 2012
Author(s)
Bo Li, Afzal A. Godil
Sketch-based 3D shape retrieval has become an important research topic in content-based 3D object retrieval. The aim of this track is to measure and compare the performance of sketch-based 3D shape retrieval methods implemented by different participants

Methanol, Ethanol, and Hydrogen Sensing using Metal-Oxide and Metal (TiO subscript 2-Pt) Composite Nanoclusters on GaN Nanowires: A New Route towards Tailoring the Selectivity of Nanowire-Nanocluster based Chemical Sensors.

May 12, 2012
Author(s)
Geetha G. Aluri, Abhishek Motayed, Albert Davydov, Vladimir Oleshko, Kristine A. Bertness, Norman Sanford, Mulpuri V. Rao
We demonstrate a new method for tailoring the selectivity of chemical sensors using nanowires decorated with multicomponent nanoclusters (metal and metal-oxide)-based hybrid sensors. In the present study we demonstrate the change of selectivity of titanium

Formation of dAMP-glycerol and dAMP-Tris derivatives by the Thermococcus kodakaraensis DNA primase

May 11, 2012
Author(s)
Zvi Kelman, John P. Marino, Jerard Hurwitz, Wiebke Chemnitz Galal, Miao Pan, Gary Giulian, Wei Yuan, Shuwei Li
In the presence of dATP, glycerol and Tris buffer, the DNA primase isolated from Thermococcus kodakaraensis (Tk) catalyzed the formation of two products that were identified as dAMP-glycerol and dAMP-Tris. These products were formed by the Tk p41 catalytic

Neutron reflectivity characterization of the photoacid reaction-diffusion latent and developed images of molecular resists for extreme-ultraviolet lithography

May 11, 2012
Author(s)
Vivek M. Prabhu, Shuhui Kang, Wen-Li Wu, Sushil K. Satija, Christopher K. Ober, Jing Sha, Peter V. Bonnesen
Lithographic feature size requirements have approached a few radius of gyration of chemically-amplified photoresist polymers used in thin film patterning. Further, the feature dimensions are commensurate with the photoacid diffusion length that defines the

Two-Way Link for Time Interval Comparison of Optical Clocks over Free-Space

May 11, 2012
Author(s)
Fabrizio R. Giorgetta, William C. Swann, Ian R. Coddington, Esther Baumann, Jean-Daniel Deschenes, Laura C. Sinclair, Alexander M. Zolot, Nathan R. Newbury
We demonstrate a free-space link for clock comparisons based on the two-way exchange of pulse trains from combs. The residual uncertainty is 5 * 10^17 in 100 seconds over a 120 m air path, with longer distances possible.

The Pan-STARRS1 Photometric System

May 10, 2012
Author(s)
J. L. Tonry, Christopher W. Stubbs, Keith R. Lykke, Peter Doherty, I. S. Shivvers, W. S. Burgett, K. C. Chambers, K. W. Hodapp, N. Kaiser, R -. Kudritzki, E. A. Magnier, J. S. Morgan, P. A. Price, R. J. Wainscoat
The Pan-STARRS1 survey is collecting multi-epoch, multi-color observations of the sky north of declination −30 to unprecedented depths. These data are being photometrically and astrometrically calibrated and will serve as a reference for many other

Algorithm Validation Using Multicolor Phantoms

May 9, 2012
Author(s)
Daniel V. Samarov, Matthew L. Clarke, Ji Y. Lee, David W. Allen, Maritoni A. Litorja, Jeeseong Hwang
We present a framework for hyperspectral image (HSI) analysis validation, specifically abundance fraction estimation based on HSI measurements of water soluble dye mixtures printed on microarray chips. In our work we focus on the performance of two

Designing Microarrays Phantoms for Hyperspectral Imaging Validation

May 9, 2012
Author(s)
Matthew L. Clarke, Ji Y. Lee, Daniel V. Samarov, David W. Allen, Maritoni A. Litorja, Ralph Nossal, Jeeseong Hwang
The simple design of custom-tailored microarrays for the characterization of hyperspectral imaging systems and analysis methods for biologically relevant samples. Individual and mixtures of dyes were printed on microscope slides and imaged by a

Structure and stability of hydrated ss-MnO2 surfaces

May 9, 2012
Author(s)
Gloria A. Oxford, Anne M. Chaka
Hydration of the β-MnO2 (110), (100), and (101) surfaces is investigated using a combination of periodic density functional theory and ab initio thermodynamics. Fully hydrated surfaces are found to be significantly more stable than the stoichiometric ones

Computer Security Division 2011 Annual Report

May 8, 2012
Author(s)
Patrick D. O'Reilly
Title III of the E-Government Act of 2002, entitled the Federal Information Security Management Act (FISMA) of 2002, requires NIST to prepare an annual public report on activities undertaken in the previous year, and planned for the coming year, to carry

Probing the Water Content in Polymer Electrolyte Fuel Cells Using Neutron Radiography

May 8, 2012
Author(s)
Daniel S. Hussey, Jeffrey Mishler, Yun Wang, Rangachary Mukundan, Jacob Spendelow, Rodney Borup
This in-situ study examines the water content in polymer electrolyte fuel cells (PEFCs) using neutron radiography. Various conditions such as different polytetraflouroethylene (PTFE) loadings in the gas diffusion media including the micro-porous layer (MPL

TRECVID 2011 -- An Overview of the Goals, Tasks, Data, Evaluation Mechanisms, and Metrics

May 8, 2012

Paul D. Over, George M. Awad, Jonathan G. Fiscus, Brian Antonishek, Martial Michel, Alan Smeaton, Wessel Kraaij, Georges Quenot
The TREC Video Retrieval Evaluation (TRECVID) 2011 was a TREC-style video analysis and retrieval evaluation, the goal of which remains to promote progress in content-based exploitation of digital video via open, metrics-based evaluation. Over the last ten

An Overview of Polymer Electrolyte Membranes for Fuel Cell Applications

May 7, 2012
Author(s)
Brandon W. Rowe, Kirt A. Page
While fuel cells have receive considerable attention over the last 10-20 years, the history of hydrogen fuel cells dates back to 1838. It would take more than a century before polymers would be impletmented as an electrolyte for proton transport (1955) and
