Dynamics of Phospholipid Membranes Beyond Thermal Undulations

June 7, 2018
Author(s)
Sudipta Gupta, Judith U. De Mel, Rasangi M. Perera, Piotr Zolnierczuk, Markus Bleuel, Antonio Faraone, Gerald J. Schneider
We investigated the molecular dynamics of unilamellar lipsomes by neutron spin echo spectroscopy. We report the first experimental evidence of a short-range motion at the length-scale of the size of the head group of a lipid. The associated mean square

Final Report for CCQM-K6.2: Determination of Total Cholesterol in Human Serum

June 7, 2018
Author(s)
Stephen Wise, Karen W. Phinney, David L. Duewer
Cholesterol is one of the most frequently measured substances in human blood/serum to assist in assessing the health status of individuals. Because of its clinical significance, CCQM-K6 Determination of Cholesterol in Serum was completed in 2000 as one of

Security Recommendations for Server-based Hypervisor Platforms

June 7, 2018
Author(s)
Ramaswamy Chandramouli
The Hypervisor platform is a collection of software modules that provides virtualization of hardware resources (such as CPU, Memory, Network and Storage) and thus enables multiple computing stacks (made of an operating system (OS) and application programs)

State-of-the-Art in Human-Robot Interaction

June 7, 2018
Author(s)
Jeremy Marvel, Megan Zimmerman, Shelly Bagchi
In this chapter, we will discuss the applications of HRI and HMI in industrial robotics, and will discuss topics such as collaborative robot safety, advances in HMI designs and development paradigms, and the current state of HRI. Throughout the following

Electronic Properties and Structure of Single Crystal Perylene

June 6, 2018
Author(s)
Sujitra J. Pookpanratana, Katelyn Goetz, Emily G. Bittle, Hamna Haneef, Lin You, Christina A. Hacker, Steven W. Robey, Oana Jurchescu, Ruslan Ovsyannikov, Erika Giangrisostomi
The transport properties of electronic devices made from single crystalline molecular semiconductors outperform those composed of thin-films. To further understand the superiority of these extrinsic properties, an understanding of the intrinsic electronic

Experimental Fire-Simulator For Post-Flashover Compartment Fires

June 6, 2018
Author(s)
Daniel Brandon, Joachim Schmid, Joseph Su, Matthew Hoehler, Birgit Ostman, Amanda Kimball
The number of tall timber buildings around the world is rapidly increasing as a result of changes in regulations and the development of new engineered timber products. However, due to the combustibility of timber, the fire safety of tall timber buildings

FIRE PERFORMANCE OF LONG-SPAN COMPOSITE BEAMS WITH GRAVITY CONNECTIONS

June 6, 2018
Author(s)
Lisa Y. Choe, Selvarajah Ramesh, Mina S. Seif, Matthew S. Hoehler, William L. Grosshandler, John L. Gross, Matthew F. Bundy
Prescriptive fire-resistance ratings for structural components provide limited insight into the system-level performance of steel-concrete composite structures in fire. Specifically, long- span composite beam assemblies exposed to fire have vulnerabilities

HYBRID FIRE TESTING OF A SINGLE DEGREE-OF-FREEDOM LINEAR SYSTEM

June 6, 2018
Author(s)
Ana Sauca, Chao Zhang, Artur A. Chernovsky, Mina S. Seif
As the structural engineering industry transitions towards performance based design methods, a better understanding of the performance of structures as full systems, especially under extreme loading conditions like fire, becomes a must. Full scale testing

Short-wave infrared compressive imaging of single photons

June 6, 2018
Author(s)
Thomas Gerrits, Daniel Lum, Varun B. Verma, John Howell, Richard P. Mirin, Sae Woo Nam
We present a short-wave infrared (SWIR) single photon camera based on a single superconducting nanowire single photon detector (SNSPD) and compressive imaging. We show SWIR single photon imaging at a megapixel resolution with a low signal-to-background

Amplitude Mode in the Planar Triangular Antiferromagnet Na 0.9 MnO 2

June 5, 2018
Author(s)
Rebecca L. Dally, Yang Zhao, Zhijun Xu, Robin Chisnell, M. B. Stone, Jeffrey W. Lynn, Leon Balents, Stephen D. Wilson
Amplitude modes that arise from continuous symmetry breaking in materials are of broad interest as condensed matter analogs of the Higgs boson in particle physics. These modes reflect an oscillation in the amplitude of a complex order parameter, yet they

Large T1 contrast enhancement using superparamagnetic nanoparticles in ultra-low field MRI

June 5, 2018
Author(s)
Xiaolu Yin, Stephen E. Russek, Gary Zabow, Fan Sun, Jeotikanta Mohapatra, Kathryn E. Keenan, Michael A. Boss, Hao Zeng, Sy-Hwang Liou, John M. Moreland
Superparamagnetic iron oxide nanoparticles (SPIONs) are widely investigated and utilized as magnetic resonance imaging (MRI) contrast and therapy agents due to their large magnetic moments. Local field inhomogeneities caused by these high magnetic moments

Application of Digital Image Correlation to Structures in Fire

June 4, 2018
Author(s)
Christopher M. Smith, Matthew Hoehler
The behavior of engineering structures in fire is commonly studied through large-scale experiments. However, temperature-varying material properties, spatially-varying thermal loading and complicated structure geometries result in these structures

Demonstration of a Chamber for Strain Mapping of Steel Specimens Under Mechanical Load in a Hydrogen Environment by Synchrotron Radiation

June 4, 2018
Author(s)
Matthew J. Connolly, Peter E. Bradley, Damian S. Lauria, Andrew J. Slifka, Elizabeth S. Drexler
We present a demonstration of a chamber for diffraction measurements of lattice strain for specimens in hydrogen gas under mechanical load. The chamber is suitable for static and cyclic mechanical loading. Synchrotron x-ray radiographs of a fatigue crack
