A Phase-Field Model for High Anisotropic InterfaciEnergy

January 1, 2001
Author(s)
Geoffrey B. McFadden, J J. Eggleston, P W. Voorhees
A computationally efficient phase-field model is developed for two-phase systems with anisotropic interfacial energy. The approach allows for anisotropies sufficiently high that the interface has corners or missing crystallographic orientations. The method

A Refinement-Tree Based Partioning Method for Adaptively Refined Grids

January 1, 2001
Author(s)
William F. Mitchell
The partitioning of an adaptive grid for distribution over parallel processors is considered in the context of adaptive multilevel methods for solving partial differential equations. A k-way refinement-tree based partitioning method is presented. Numerical

A Surface Chemistry Study of Laser Ablated Plastics Used for Microfluidic Devices

January 1, 2001
Author(s)
D P. Pugmire, E A. Waddell, Michael J. Tarlov
Plastic substrates are being investigated for use in microfluidic devices because of their low cost, ease of fabrication, and wide range of materials properties. It is well established that the surface chemistry of a plastic substrate greatly influences

A U.S. Laser-Cooled Atomic-Clock System for Space

Donald Sullivan, Thomas P. Heavner, Leo W. Hollberg, D Meekhof, Thomas E. Parker, William D. Phillips, S L. Rolston, Hugh Robinson, Jon H. Shirley, F L. Walls, Neil Ashby, W Kepstein, L Maleki, D Seidel, R Q. Thompson, S Wu, L Young, R Vessot, E Mattison, A Demarchi

Absolute Frequency Measurement of the Iodine-Stabilized He-Ne Laser at 633 nm

January 1, 2001
Author(s)
T H. Yoon, J Ye, John L. Hall, J M. Chartier
The absolute frequency of an iodine-stabilized He-Ne laser at 633 nm stabilized on the I (or a 13) component of the 11-5 R(127) hyperfine transition of the 127I 2molecule is measured using a femtosecond optical comb generator and an iodine-stabilized Nd
