Uncertainty in RECIST as a measure of volume for lung nodules and liver malignoma

April 27, 2012
Author(s)
Zachary H. Levine, Adam L. Pintar, John G. Hagedorn, Charles D. Fenimore, Claus P. Heussel
The authors investigate the extent to which the RESPONSE Evaluation Criateria in Solid Tumors (RECIST) can predict tumor volumes and changes in volume using clinical data. The data presented are a reanalysis of data acquired in other studies, including the

Anti-Drain Requirements for Retail Motor-fuel Dispensers

April 26, 2012
Author(s)
Marc A. Buttler
Two of the most fundamental components that can be found in any liquid fuel dispenser are the measuring device and the hose that transports the metered product to the consumers vehicle. The fuel that fills the volume of space in between the measuring

Characterizing Heat Release Rate Transients

April 26, 2012
Author(s)
Rodney A. Bryant, Erik L. Johnsson, George W. Mulholland
A series of experiments was performed to characterize the time response of a large-scale open calorimeter to square-wave pulses in terms of peak heat release rate, width of the peak, and conservation of energy. Quantitative heat release rate measurements

Engineered two-dimensional Ising interactions on a trapped-ion quantum simulator with hundreds of spins

April 26, 2012
Author(s)
Joseph W. Britton, Brian C. Sawyer, Adam Keith, C.-C. Joseph Wang, James K. Freericks, Hermann Uys, Michael Biercuk, John J. Bollinger
The presence of long-range quantum spin correlations underlies a variety of physical phenomena in condensed matter systems, potentially including high-temperature superconductivity, making this a fertile area for exploration. Unfortunately, many properties

Influence of solvent washing on interlayer structure of alkylammonium montmorillonites

April 26, 2012
Author(s)
Wayne L. Elban, John A. Howarter, Mickey C. Richardson, Paul E. Stutzman, Aaron M. Forster, Adam J. Nolte, Gale A. Holmes
Powdered samples of montmorillonite were functionalized with ammonium surfactants of various chain lengths and subjected to two different constant volume washing procedures: water only or sequential ethanol-water. The organo-functionalized montmorillonite

Pro-oxidant Induced DNA Damage in Human Lymphoblastoid Cells: Homeostatic Mechanisms of Genotoxic Tolerance

April 26, 2012
Author(s)
Bryant C. Nelson, Bryce J. Marquis, Anna L. Seager, Ume K. Shah, Jane M. Mikhail, Shareen H. Doak, George E. Johnson, Paul L. Carmichael, Sharon J. Scott, Andrew D. Scott, Gareth J. Jenkins
Oxidative stress contributes to many disease aetiologies including ageing, neurodegeneration, and cancer, partly through DNA damage induction (genotoxicity). Understanding the interactions of free radicals with DNA is fundamental to discern the mutation

Stimulated Generation of Superluminal Light Pulses via Four-wave Mixing

April 26, 2012
Author(s)
Ryan T. Glasser, Ulrich Vogl, Paul D. Lett
We report on the four-wave mixing of superluminal pulses, in which both the injected and generated pulses involved in the process propagate with negative group velocities. Generated pulses with negative group velocities of up to vg = −c/880 are
