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
