Variability and bias assessment in breast ADC measurement across multiple systems

February 29, 2016
Author(s)
Kathryn E. Keenan, Sheye O. Aliu, Lisa J. Wilmes, David C. Newitt, Ella F. Jones, Wen Li, Michael A. Boss, Karl F. Stupic, Stephen E. Russek, Nola M. Hylton
Purpose: To assess the ability of a recent, anatomically designed breast phantom incorporating T 1 and diffusion elements to serve as a quality control device for quantitative comparison of apparent diffusion coefficient (ADC) measurements calculated from

Linkage-Specific Conformational Ensembles of Non-Canonical Polyubiquitin Chains

February 28, 2016
Author(s)
Carlos A. Castaneda, Apurva Chaturvedi, Christina M. Camara, Joseph E. Curtis, Susan T. Krueger, David Fushman
Polyubiquitination is a critical protein post-translational modification involved in a variety of processes in eukaryotic cells. The molecular basis for selective recognition of the polyubiquitin signals by cellular receptors is determined by the

The CALPHAD method and its role in material and process development

February 26, 2016
Author(s)
Ursula R. Kattner
Successful design of materials and manufacturing processes requires the availability of reliable materials data. Commercial alloys usually contain a large number of elements, and the needed data for the design of new materials and processes are rarely

The Magnetic Transitions and Dynamics in the Multiferroic Lu 0.5 Sc 0.5 FeO 3

February 26, 2016
Author(s)
Junjie Yang, Chunruo Duan, John R. Copley, Craig Brown, Despina Louca
In spite of its frustrated lattice, the multiferroic Lu 0.5Sc 0.5FeO 3 exhibits two consecutive magnetic transitions at T% N1approximately equal to}175 K and T N2 approximately equal to}70 K determined from neutron diffraction. In the ordered state

Manipulating Three-Dimensional Gel Network Entanglement by Thin Film Shearing

February 25, 2016
Author(s)
Harshita Kumari, Steven R. Kline, Stuart R. Kennedy, Christopher Garvey, Colin L. Raston, Jerry L. Atwood, Jonathan W. Steed
Vortex fluidic mediated shearing of supramolecular gels in thin films leads to complete disruption of fluorous bis-urea derived gels. Hydrocarbon analogues however, are only partially disrupted, which emphasizes the resistance of nonfluorous bis-urea

Optimization of Registration Performance Metrics

February 25, 2016
Author(s)
Marek Franaszek, Geraldine Cheok
Perception systems are a very important component of automation and robotics. These systems localize objects in its local coordinate frame and the data has to be available for use in another coordinate frame. This requires that the data be transformed from

The Structural Origin of Electron Injection Enhancements with Fulleropyrrolidine Interlayers

February 25, 2016
Author(s)
Lee J. Richter, Hyunbok Lee, Christopher McNeil, Eliot Gann, Lars Thomsen, S. Park, J. Jeong, Z. A. Page, Egle Puodziukynaite, Todd Emrick, Alejandro Briseno, John C. Stephenson, Dean M. DeLongchamp
Market demand for ubiquitous, increased functionality products at low cost (the internet of things) is spurring development in additive, solution processing of electronic devices. Performance in thin-film functional devices, be they transistors, diodes, or

Through-the-Glass Spectroscopic Ellipsometry for Analysis of CdTe Thin-Film Solar Cells in the Superstrate Configuration

February 25, 2016
Author(s)
Prakash Koirala, Jian Li, Heayoung Yoon, Puruswottam Aryal, Sylvain Marsillac, Angus R. Rockett, Nikolas Podraza, Robert W. Collins
Polycrystalline CdS/CdTe thin-film solar cells in the superstrate configuration have been studied by spectroscopic ellipsometry (SE) using glass side illumination. In this measurement method, the first reflection from the ambient/glass interface is

Validation and Verification of Collisional-Radiative Models

February 25, 2016
Author(s)
Yuri Ralchenko
Quality control is as relevant to scientific computing as to any other software. For complex collisional-radiative (CR) models that are used to calculate plasma population kinetic parameters and spectra, each computer code is expected to be thoroughly

Reversible Control of Magnetism in La 0.67 Sr 0.33 MnO 3 through Chemically-Induced Oxygen Migration

February 24, 2016
Author(s)
Alexander J. Grutter, Dustin A. Gilbert, U. S. Alaan, E. Arenholz, Brian B. Maranville, Julie A. Borchers, Y. Suzuki, Kai Liu, Brian J. Kirby
We demonstrate reversible control of magnetization and anisotropy in La 0.67Sr 0.33MnO 3 films through interfacial oxygen migration. Gd metal capping layers deposited onto La 0.67Sr 0.33MnO 3 leach Oxygen from the film through a solid-state redox reaction
