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

Analytical Electron Microscopy of Semiconductor Nanowire Functional Materials and Devices for Emerging Applications.

Vladimir P. Oleshko, Elissa H. Williams, Albert Davydov, Sergiy Krylyuk, Abhishek Motayed, Dmitry A. Ruzmetov, Thomas F. Lam, Henri J. Lezec, Albert A. Talin
Functionalized individual semiconductor nanowires (SNWs) and 3D SNW arrays attract a continuously growing interest for applications in optoelectronics, sensing, and energy storage. High-resolution field-emission analytical (S)TEM enables critical insights

Frictional properties of native and functionalized type I collagen thin films

Koo-hyun Chung, Antony Chen, Christopher Anderton, Kiran Bhadriraju, Anne L. Plant, Brian G. Bush, Robert F. Cook, Frank W. DelRio
Frictional properties of native and fibronectin (FN)-functionalized type I collagen (COL) thin films were studied via atomic force microscopy. The COL lateral contact stiffness was dependent only on the hydration state, indicating that shear deformation
