Temperature extrapolation of multicomponent grand canonical free energy landscapes

August 7, 2017
Author(s)
Nathan Mahynski, Jeffrey R. Errington, Vincent K. Shen
We derive a method for extrapolating the grand canonical free energy landscape of a multicomponent fluid system from one temperature to another. Previously, we introduced this statistical mechanical framework for the case where kinetic energy contributions

Metagenomic assembly through the lens of validation: a review of recent advances in assessing and improving the quality of genes and genomes assembled from metagenomes.

August 6, 2017
Author(s)
Nathanael Olson, Chris M. Hill, Vistoria Cepeda-Espinoza, Jay Ghurye, Sergey Koren, Todd J. Treangen, Mihai Pop
Metagenomic samples are snapshots of complex ecosystems at work. These samples often involve hundreds of bacteria from known and unknown species, contain multiple strain variants, and vary greatly both within and across environments. Many microbes found in

Heron Quadrilaterals via Elliptic Curves

August 5, 2017
Author(s)
Farzali Izadi, Foad Khoshnam, Dustin Moody
A Heron quadrilateral is a cyclic quadrilateral with rational area. In this work, we establish a correspondence between Heron quadrilaterals and a family of elliptic curves of the form y^2=x^3+\alpha x^2-n^2 x. This correspondence generalizes the notions

3.5 GHz Radar Waveform Capture at Fort Story

August 4, 2017
Author(s)
Paul D. Hale, Jeffrey A. Jargon, Peter J. Jeavons, Michael R. Souryal, Adam J. Wunderlich, Mark Lofquist
We describe measurements to create a library of high-fidelity waveforms of federal incumbent radar signals currently operating in the 3550 MHz – 3650 MHz (“3.5 GHz”) band. In this second phase of assembling the library, measurements were collected at Fort

Identifying Vulnerable Populations to Death and Injuries from Residential Fires

August 4, 2017
Author(s)
Stanley W. Gilbert, David T. Butry
Residential fire casualty risk is a function of an individual’s exposure risk and vulnerability. The previous literature focuses on measuring correlations between socioeconomic factors and casualties, and identifies at-risk population. This study controls

Microanalysis: What Is It, Where Did It Come From, and Where Is It Going?

August 4, 2017
Author(s)
Dale E. Newbury
"Microanalysis" in the parlance of the Microanalysis Society (MAS) refers to spatially-resolved elemental and molecular analysis performed at the micrometer to nanometer to picometer scales by any combination of excitation and analytical spectrometry that

Multiple method analysis of TiO2 nanoparticles uptake, accumulation and effects in rice (Oryza sativa L.) plants

August 4, 2017
Author(s)
Yinqging Deng, Elijah Petersen, Katie Challis, Savelas A. Rabb, Richard D. Holbrook, James Ranville, Bryant C. Nelson, Baoshan Xing
Understanding the translocation of nanoparticles (NPs) into plants is challenging because quantitative and qualitative methods are still being developed and the comparability of results among different methods is unclear. In this study, the uptake of NPs
