Attractive Interactions between DNA-Carbon Nanotube hybrids in Monovalent Salts

June 30, 2016
Author(s)
Ming Zheng, Xiangyun Qiu, Fuyou Ke, Raju Timsina, Constantine Y. Khripin
DNA-carbon nanotube (DNA-CNT) hybrids are nanometer-sized, highly-charged, rod-like molecules with complex surface chemistry, and their behaviors in aqueous solutions are governed by multifactorial interactions with both solvent and co-solutes. We have

Crystal Plasticity Analysis of Constitutive Behavior of 5754 Aluminum Sheet

June 30, 2016
Author(s)
Minh-Son Pham, Anthony D. Rollett, Adam Abel Creuziger, Mark Iadicola, Timothy J. Foecke
Crystal plasticity constitutive equations for the multi-axial stress-strain behavior of aluminum alloy 5754 sheets have been developed. A Taylor model, a self-consistent visco-plastic model and an N-site model based on the Fast Fourier Transform were used

Fast Dynamic Programming for Elastic Registration of Curves

June 30, 2016
Author(s)
Javier Bernal, Gunay Dogan, Robert Hagwood
Curve registration problems in data analysis and com- puter vision can often be reduced to the problem of match- ing two functions defined on an interval. Dynamic Pro- gramming (DP) is an effective approach to solve this prob- lem. In this paper, we

Identifying uncertainty in Laser Powder Bed Fusion models

June 30, 2016
Author(s)
Felipe F. Lopez, Paul Witherell, Brandon Lane
A limitation frequently encountered in additive manufacturing (AM) models is a lack of indication about their precision and accuracy. Often overlooked, information on model uncertainty is required for validation of AM models, qualification of AM-produced

Methodology for Increasing Image Feature Measurement Accuracy

June 30, 2016
Author(s)
Michael Paul Majurski, Joe Chalfoun, Steven Lund, Peter Bajcsy, Mary C. Brady
Motivation Image features are computed in cell biology to derive quantitative information regarding cell state, differentiation, biological activity, and cell dynamics. The accuracy of any biological conclusions depends on the accuracy of the measured

Neutron Scattering Studies of Lithium-Ion Diffusion in Ternary Phosphate Glasses

June 30, 2016
Author(s)
Gavin Hester, Tom Heitmann, Madhu Sudan Tyagi, Munesh Rathore, Anshuman Dalvi, Saibal Mitra
We have studied the diffusion mechanism of lithium ions in glassy oxide-based solid sate electrolytes using elastic and electrolytes using elastic and quasielastic neutron scattering. Samples of xLi 2SO 4-(1-x)(Lid2^O-P 2O 5) were prepared using

Survey of Research for Performance Measurement of Mobile Manipulators

June 30, 2016
Author(s)
Roger V. Bostelman, Tsai H. Hong, Jeremy A. Marvel
This survey provides the basis for developing research in the area of mobile manipulator performance measurement, an area that has relatively few research articles, as com-pared to other mobile manipulator research areas. The survey begins with a

Stability of Single Electron Devices: Charge Offset Drift

June 29, 2016
Author(s)
Michael D. Stewart, Neil M. Zimmerman
Abstract: Single electron devices (SEDs) afford the opportunity to isolate and manipulate individual electrons. This ability imbues SEDs with potential applications in a wide array of areas from metrology (current and capacitance) to quantum information

A Guide to United States Furniture Compliance Requirements

June 28, 2016
Author(s)
Karen Reczek, lisa benson
This guide addresses children’s furniture, upholstered furniture and other types of furniture. This document does NOT address mattresses or other home furnishings such as carpets and rugs.

A Hybrid Human-Computer Approach to the Extraction of Scientific Facts from the Literature

June 28, 2016
Author(s)
Roselyne B. Tchoua, Kyle Chard, Debra Audus, Jian Qin, Juan J. de Pablo, Ian Foster
A wealth of valuable data is locked within the millions of research articles published each year. Reading and extracting pertinent information from those articles has become an unmanageable task for scientists. This problem hinders scientific progress by
