This bulletin summarizes the information presented in NIST Special Publication (SP) 800-128, Guide to Security-Focused Configuration Management of Information Systems. The publication was written by Arnold Johnson, Kelley Dempsey, and Ron Ross of NIST, and

Segmentation and Cell Tracking of Breast Cancer Cells

September 26, 2011
Author(s)
Adele P. Peskin, Daniel J. Hoeppner, Christina H. Stuelten
We describe a new technique to segment and track the cell images of a breast cancer cell line in order to study cell migration and metastasis. Within each image cell phenotypes vary widely, ranging from very bright completely bounded cells to barely

Tare Verification - Ensuring the Accuracy of Tare

September 26, 2011
Author(s)
David A. Sefcik
Article for Weights and Measures Division "Connections" newsletter. Article discusses a suggested procedure for weights and measures officials to verify the accuracy of tare being used by the retailer before an official inspection is done.

September 26, 2011
Author(s)
Kenneth G. Kroenlein, Vladimir Diky, Chris D. Muzny, Robert D. Chirico, Joe W. Magee, Michael D. Frenkel
This web application provides free and open access for the broader research community to the experimental planning utilities that are incorporated into ThermoData Engine (TDE) [J. Chem. Inf. Model. 2011, 51, 181–194]. TDE provides recommendations for the

An Iterative Algorithm for Calculating Stylus Radius Unambiguously

September 24, 2011
Author(s)
Theodore V. Vorburger, Xiaoyu A. Zheng, Thomas B. Renegar, Jun-Feng Song, Li Ma
The stylus radius is an important specification for stylus instruments and is commonly provided by instrument manufacturers. However, it is difficult to measure the stylus radius unambiguously. Accurate profiles of the stylus tip may be obtained by
