Contrasting Transport and Electrostatic Properties of Selectively Fluorinated Alkanethiol Monolayers with Embedded Dipoles

February 7, 2018
Author(s)
Robert C. Bruce, Lin You, Anja Forster, Sujitra J. Pookpanratana, Olivia Pomerenk, Han Ju Lee, Maria D. Marquez, Rashid Ghanbaripour, Oussama Zensani, T R. Lee, Christina A. Hacker
Surface dipoles are a powerful tool in interfacial modification for improving device output via energy level matching. Fluorinated alkanethiols show strong promise for these applications as they can generate large and tunable dipoles based on fluorine

Knot Energy, Complexity, and Mobility of Knotted Polymers

October 17, 2017
Author(s)
Luis F. Vargas Lara, Ahmed M. Hassan, Marc A. Mansfield, Jack F. Douglas
The Newtonian capacity C of an object is defined by the equilibrium energy, EN =1/C, of a charge distribution on a conductive object and provides a classical measure of object shape. It is well known, for example, that C is minimized for a sphere for all

Fire Structure Interface for the World Trade Center Towers

February 19, 2017
Author(s)
Kuldeep Prasad, Howard R. Baum
The collapse of the World Trade Center towers on September 11, 2001, resulting from a combination of aircraft impact damage and subsequent fires, was studied as part of the Federal Building and Fire Safety Investigation of the World Trade Center Disaster

A Category Theoretic Approach to Modeling and Analysis Using Music as a Case Study

January 31, 2017
Author(s)
Sarala Padi, Spencer J. Breiner, Eswaran Subrahmanian, Ram D. Sriram
The goal of this paper is to provide a category theoretic ontology for the creation of a collaborative platform where it allows group of people to share or use the knowledge in a domain. We use Indian music as a case study to demonstrate the power of

Entropy Theory of Polymer Glass-Formation in Variable Spatial Dimension

December 20, 2016
Author(s)
Jack F. Douglas, Wensheng Xu, Karl Freed
The importance of packing frustration is broadly appreciated to be an important aspect of glass formation. Recently, great interest has focused on probing the dependence on spatial dimension d as a theoretical tool for exploring essential aspects of glass

Soliton crystals in Kerr microresonators

July 18, 2016
Author(s)
Daniel C. Cole, Erin S. Lamb, Pascal P. Del'Haye, Scott A. Diddams, Scott B. Papp
Solitons are pulses which propagate without spreading due to a balance between nonlinearity and dispersion or diffraction, and are universal features of systems exhibiting these effects. They are important in plasma physics, fluid dynamics, atomic physics

3D Segmentation of Stem Cells from Thousands of Confocal Microscopy Images

March 1, 2016
Author(s)
Peter Bajcsy, Mylene H. Simon, Stephen J. Florczyk, Carl G. Simon Jr., Derek Juba, Mary C. Brady
We address the problem of estimating 3D segmentation performance when segmentation is applied to thousands of confocal microscopy images (z-stacks) of cells. With a very large number of z-stacks, manual inputs to validate each segmentation result are

A real microstructural model for cement concrete modeling

May 24, 2015
Author(s)
Edward J. Garboczi, Yang Lu, Stephen Thomas
Existing concrete microstructural models of particles embedded in matrix materials are only represented by regular shape particles like spheres, ellipsoids, or multi-faceted polyhedrons. However, the real particle shapes are more complex and sometimes play

Confronting the Complexity of Commercial Carbon Nanotube Materials

May 13, 2015
Author(s)
Luis Fernando Vargas Lara, Jack F. Douglas
The morphology of commercially available carbon nanotube materials is often much more complex than the term “carbon nanotube” (CNT) would imply. Commercial CNT materials are typically composed of roughly spherical CNT domains having a highly ramified

Long-Term Uncertainty in Time Transfer Using GPS and TWTFT Techniques

April 13, 2015
Author(s)
Victor S. Zhang, Thomas E. Parker, Jian Yao
The techniques of GPS time and frequency transfer (code based and carrier phase) and two-way satellite time and frequency transfer (TWSTFT) are widely used in remote clock comparison and in the computation of International Atomic Time (TAI). Many timing

CPTAC Studies 1 and 5: dissecting variability in multi-site LC-MS/MS proteomics through quality metrics and robust hierarchical multivariate statistics

February 4, 2014
Author(s)
Stephen E. Stein, David M. Bunk, Xia Wang, Matthew Chambers, Lorenzo J. Vega-Montoto, David L. Tabb
Shotgun proteomics experiments integrate a complex sequence of processes, any of which can introduce variability. Quality metrics computed from LC-MS/MS data have relied upon identifying MS/MS scans, but a new mode for the QuaMeter software produces

Thermal Properties and Thermal Modeling of Ballistic Clay Box

December 30, 2011
Author(s)
Dale P. Bentz, Amanda L. Forster, Kirk D. Rice, Michael A. Riley
A critical component of hard and soft body armor testing is the utilization of a clay block behind the component being evaluated. One of the performance metrics used to evaluate products is the penetration depth into the clay of an indentation produced by

Vulnerability Hierarchies in Access Control Configurations

December 27, 2011
Author(s)
David R. Kuhn
This paper applies methods for analyzing fault hierarchies to the analysis of relationships among vulnerabilities in misconfigured access control rule structures. Hierarchies have been discovered previously for faults in arbitrary logic formulae, such that
