Magnetoelastic Coupling in La 0.7 Ca 0.3 MnO 3 /BaTiO 3 Ultrathin Films

October 11, 2013
Author(s)
A. Alberca, N. M. Nemes, F. J. Mompean, Titusz Feher, Ferenc Simon, J. Tornos, C. Leon, C. Munuera, Brian Kirby, M. R. Fitzsimmons, A. Hernando, J. Santamaria, M. Garcia-Hernandez
The magnetism of La 0.7Ca 0.3MnO 3 (LCMO) expitaxial thin films grown SrTi 3 (STO)and BaTiO 3 (BTO) substrates is studied using Polarized Neutron Reflectometry (PNR) and Ferromagnetic Resonance (FMR) techniques. PNR reveals a strongly suppressed

Pretreatment with Pyridoxamine Mitigates Isolevuglandinassociated Retinal Effects in Mice Exposed to Bright Light

October 11, 2013
Author(s)
Casey Charvet, Aicha Saadane, Meiyao M. Wang, Robert Salomon, Henri Brunengraber, Christine Curcio, Illarion Turko, Irina Pikuleva
The benefits of antioxidant therapy for treating age-related macular degeneration, a devastating retinal disease, are limited. Perhaps species other than reactive oxygen intermediates should be considered as therapeutic targets. These could be lipid

Small-Angle Neutron Scattering Study of a Monoclonal Antibody Using Free-Energy Constraints

October 11, 2013
Author(s)
Nicholas James Clark, Hailiang Zhang, Susan T. Krueger, Hyo Jin Lee, Randy R. Ketchem, Bruce Kerwin, Sekhar R. Kanapuram, Michael J. Treuheit, Arnold McAuley, Joseph E. Curtis
Monoclonal antibodies (mAbs) contain hinge-like regions of structural flexibility that enable the mobility of globular domains that have direct effect on biological function. A subclass of human mAbs, IgG2, has several inter-chain disulfide bonds in the

CCM: A Tool for Measuring Combinatorial Coverage of System State Space

October 10, 2013
Author(s)
Itzel Dominguez, D. Richard Kuhn, Raghu N. Kacker, Yu Lei
This poster presents some measures of combinatorial coverage that can be helpful in estimating residual risk related to insufficient testing of rare interactions, and a tool for computing these measures.

Relativistic CI calculations of spectroscopic data for the 2p6 and 2p53l configurationsin Ne-like ions between Mg III and Kr XXVII

October 10, 2013
Author(s)
P. Jonsson, P. Bengtsson, J. Ekman, S. Gustafsson, L. B. Karlsson, G. Gaigalas, D. Kato, Charlotte F. Fischer, I. Murakami, H. A. Sakaue, H. Hara, T. Watanabe, N. Nakamura, N. Yamamoto
Energies, E1, M1, E2, M2 transition rates, oscillator strengths, and lifetimes from relativistic configuration interaction calculations are reported for the states of the 2p6, 2p53s, 2p53p, and 2p53d, configurations in all Ne-like ions between Mg III and

Self-consistent calculation of spin transport and magnetization dynamics

October 10, 2013
Author(s)
Kyung Jin Lee, Mark D. Stiles, Hyun-Woo Lee, Jung-Hwan Moon, Kyoung-Whan Kim, Seo--Won Lee
A spin-polarized current transfers its spin-angular momentum to a local magnetization, exciting various types of current-induced magnetization dynamics. So far, most studies in this field have focused on the direct effect of spin transport on magnetization

New Measurements on the Minimum and Maximum Sample Sizes in t-EBSD

October 9, 2013
Author(s)
Roy H. Geiss, Robert R. Keller, Katherine P. Rice
The technique of acquiring transmission electron diffraction patterns in the scanning electron microscope, SEM, using components of commercially available electron backscattered diffraction equipment, EBSD, normally used in a reflection geometry, was first

Re-Projection of Terabyte-sized 3D Images for Interactive Visualization

October 9, 2013
Author(s)
Peter Bajcsy, Antoine Vandecreme, Mary C. Brady
How does one inspect terabyte-sized 3D images visually from multiple viewpoints? The current solutions are limited to gigabyte-sized images using specialized hardware to achieve interactivity and lacking the ability to share data for collaborative research

The Seventh Industrial Fluid Properties Simulation Challenge

October 8, 2013
Author(s)
Riaz Ahmad, John K. Brennan, Kevin A. Frankel, Jonathan D. Moore, Joshua D. Moore, Raymond D. Mountain, Richard B. Ross, Vincent K. Shen, Nathan E. Schultz, Daniel Siderius, Kenneth D. Smith, Matthias Thommes
The primary goal of the seventy industrial fluid properties simulation challenge was to test the ability of molecular simulation methods to predict the adsorption of organic adsorbates in zeolite materials. Zeoliet adsorbents are used in a variety of

Effect of Binding to Carbon Black on the Dynamics of 1,4-Polybutadiene

October 7, 2013
Author(s)
J.H. Roh, Madhu Sudan Tyagi, T. E. Hogan, C. M. Roland
The nature of the interactions of polymers at the surface of nanoparticles is crucial to understanding the dynamics and their effect on the mechanical properties. The effect of binding (both chemical attachment and physical adsorption) on the local and

Efficient Dithering Technique with Periodic Waveforms for RF Test and Characterization

October 7, 2013
Author(s)
Catherine A. Remley, Saeed Farsi, Bart Nauwelaers, Dominique Schreurs
A dithering technique based on ensemble averaging of waveforms is proposed. In the proposed method, instead of performing several measurements with different dithering additive noise, a single measurement of multiple periods of a sine-dithered periodic

Fluid Transport in High-Volume Fly Ash Mixtures with and without Internal Curing

October 7, 2013
Author(s)
Igor de la Varga, Robert Spragg, Carmelo di Bella, Javier Castro, Dale P. Bentz, Jason Weiss
The transport of fluid and ions in concrete mixtures is central to many aspects of concrete deterioration. As a result, transport properties are frequently measured as an indication of the durability that a concrete mixture may be expected to have. This

Mechanism for controlling the exciton fine structure in quantum dots using electric fields: Manipulation of exciton orientation and exchange splitting at the atomic scale

October 7, 2013
Author(s)
Garnett W. Bryant, Natalia Malkova, James S. Sims
We use atomistic tight-binding theory with a configuration interaction description of Coulomb and exchange effects to describe excitons in quantum dots in a vertical electric field. We show that field-induced manipulation of exciton orientation and phase

Re-projection of Terabyte-Sized Images

October 7, 2013
Author(s)
Peter Bajcsy, Antoine Vandecreme, Mary C. Brady
This work addresses the problem of re-projecting a terabyte-sized 3D data set represented as a set of 2D Deep Zoom pyramids. In general, a re-projection for small 3D data sets is executed directly in RAM. However, RAM becomes a limiting factor for terabyte

Terabyte Size Image Computations on Hadoop Cluster Platforms

October 7, 2013
Author(s)
Peter Bajcsy, Antoine Vandecreme, Julien M. Amelot, Phuong T. Nguyen, Joe Chalfoun, Mary C. Brady
We present a characterization of four basic terabyte size image computations on a Hadoop cluster in terms of their relative efficiency according to the modified Amdahl’s law. The work is motivated by the fact that there is a lack of standard benchmarks and

Biological Uptake and Depuration of Radio-labeled Graphene by Daphnia magna

October 5, 2013
Author(s)
Xiangke Guo, Shipeng Dong, Elijah Petersen, Shiziang Gao, Qingguo Huang, Cheng Gu, Liang Mao
BACKGROUND: Graphene layers are potential candidates in a large number of applications due to their novel properties. However, little is known about their behaviors and associated potential risks largely as a result of a lack of quantification techniques
