Thermodynamic Underpinnings of Cell Alignment on Controlled Topographies

August 17, 2010
Author(s)
Yifu Ding, Jirun Sun, Hyun W. Ro, Zhen Wang, Jing N. Zhou, Nancy J. Lin, Sheng Lin-Gibson, Marcus T. Cicerone, Christopher L. Soles
Cells sense and respond to the chemical, topographical, and mechanical features of their substrate and extracellular matrix. Shape and locomotive response to these features is termed contact guidance (CG) and is of vital importance in understanding many

Comparison of Orthogonal Mass Spectrometry Platforms for the Determination of Amino Acid Concentrations in Human Plasma Certifying NIST Standard Reference Material 1950

August 16, 2010
Author(s)
Mark S. Lowenthal, Karen W. Phinney, Elizabeth A. McGaw
Absolute concentrations of amino acids in a human plasma pool were determined independently using four quantification methods. Orthogonal separation schemes (LC, GC, or GCxGC) and detection systems (triple quadrupole or time-of-flight mass spectrometers)

Broadband coherent spectroscopy in the near infrared using dual coherent frequency combs

August 15, 2010
Author(s)
Nathan R. Newbury, Ian R. Coddington, Esther Baumann, Fabrizio R. Giorgetta, William C. Swann, Alexander M. Zolot
Fiber-based frequency combs can provide broadband coherent light that enables new possibilities for high-accuracy, high-resolution broadband spectroscopy. We use a configuration with two coherently phase-locked combs; the output of one comb passes through

CT Measurements of SAP Voids in Concrete

August 15, 2010
Author(s)
Sara Laustsen, Dale P. Bentz, Marianne Hasholt, Ole M. Jensen
This paper describes how X-ray computed tomography (CT) scanning can be used to determine the void distribution in hardened concrete. Three different approaches are used to analyse a binary data set created from CT measurement. One approach classifies a

Database-Assisted Design for Wind: Veering Effects on High-Rise Structures

August 15, 2010
Author(s)
Dong Hun Yeo, Emil Simiu
Atmospheric boundary layer winds experience two types of effects due to friction at the ground surface. One effect is the increase of the wind speeds with height above the surface. The second effect, called the Ekman layer effect, entails veering -- the
