Capillary Wave Dynamics of Thin Polymer films over Submerged Nanostructures

November 16, 2012
Author(s)
Christopher L. Soles, Hyun W. Ro, K. J. Alvine, Oleg Shpyrko, Yenling Dai, Alec Sandy, Suresh Narayanan
The surface dynamics of thin molten polystyrene films supported by nanoscale periodic silicon line-space gratings were investigated with X-ray photon correlation spectroscopy. Surface dynamics over these nanostructures exhibit high directional anisotropy

A New Limit on Time-Reversal Violation in Beta Decay

September 2, 2012
Author(s)
Hans P. Mumm, T E. Chupp, K P. Coulter, R L. Cooper, S J. Freedman, B. K. Fujikawa, A. Garcia, Gordon L. Jones, Jeffrey S. Nico, Alan K. Thompson, C A. Trull, J. F. Wilkerson, F. E. Wiefeldt
We report the results of an improved determination of the triple correlation DP • (p_e × p_v) that can be used to limit possible time-reversal invariance in the beta decay of polarized neutrons and constrain extensions to the Standard Model. Our result is

Image Classification of Vascular Smooth Muscle Cells

November 11, 2010
Author(s)
Michael Grasso, Ronil Mokashi , Alden A. Dima, Antonio Cardone, Kiran Bhadriraju, Anne L. Plant, Mary C. Brady, Yaacov Yesha, Yelena Yesha
The traditional method of cell microscopy can be subjective, due to observer variability, a lack of standardization, and a limited feature set. To address this challenge, we developed an image classifier using a machine learning approach. Our system was

Outdoor-to-Indoor Channel Measurements and Models

September 1, 2009
Author(s)
Catherine A. Remley, Christopher L. Holloway, David W. Matolak
This document reports on wireless channel measurements and models for outdoor to indoor propagation environments. Although there have been a number of publications that have recently appeared on this topic, e.g., [1], [2], and references therein, the

Vulnerability Scoring for Security Configuration Settings

October 29, 2008
Author(s)
Karen A. Scarfone, Peter M. Mell
The best-known vulnerability scoring standard, the Common Vulnerability Scoring System (CVSS), is designed to quantify the severity of security-related software flaw vulnerabilities. This paper describes our efforts to determine if CVSS could be adapted

MINEX II Performance of Fingerprint Match-on-Card Algorithms - Phase II Report

February 29, 2008
Author(s)
Patrick J. Grother, Wayne J. Salamon, Michael D. Indovina, Craig I. Watson
The MINEX II trial was conducted to evaluate the accuracy and speed of Match-on-Card verification algorithms. These run on ISO/IEC 7816 smart cards. They compare conformant reference and verification instances of the ISO/IEC 19794-2 COMPACT CARD

A Multi-Criteria Web Services Composition Problem

June 20, 2007
Author(s)
Jeong Buhwan, Hyunbo Cho, Boonserm Kulvatunyou, Albert W. Jones
… The popularity, however, results in a number of different standards and implementations. The approach needs agreed-upon …
