Probing Membrane Association of a-Synuclein Domains with VDAC Nanopore Reveals Unexpected Binding Pattern

March 14, 2019
Author(s)
Daniel Jacobs, David Hoogerheide, Amandine Rovini, Zhiping Jiang, Jennifer C. Lee, Tatiana K. Rostovtseva, Sergey M. Bezrukov
It is well established that α-synuclein (α-syn) binding from solution to the surface of membranes composed of negatively charged and/or non-lamellar lipids can be characterized by equilibrium dissociation constants of tens of micromolar. Previously, we

Using Distributed Agents to Optimize Thermal Energy Storage

March 14, 2019
Author(s)
Amanda Pertzborn
The Intelligent Building Agents Laboratory (IBAL) at the National Institute of Standards and Technology (NIST) will be used to develop and evaluate advanced control systems for commercial building heating, ventilation, and air conditioning (HVAC)

Influence of Knot Complexity on Glass-Formation in Ring Polymer Melts

March 13, 2019
Author(s)
Luis F. Vargas Lara, Beatriz Pazmino, Jack F. Douglas
We perform molecular dynamic simulations on a coarse-grained polymer melt to study the dynamics of glass-formation in ring polymer melts of variable knot complexity. After generating melts of non-concatenated polymeric rings having a range of minimum

ELECTRON ENERGY-LOSS SPECTROSCOPY AND IMAGING

March 12, 2019
Author(s)
Vladimir P. Oleshko
This article describes electron energy-loss spectroscopy (EELS), energy-filtering transmission electron microscopy (EFTEM) and electron spectroscopic diffraction (ESD) in a transmission electron microscope (TEM) or in a scanning transmission electron

High-Throughput, DC-Parametric Evaluation of Flux-Activated-Switch-Based TDM and CDM SQUID Multiplexers

March 12, 2019
Author(s)
Carl D. Reintsema, Douglas A. Bennett, Edward V. Denison, Malcolm S. Durkin, William B. Doriese, Joseph W. Fowler, Johnathon D. Gard, Arpi L. Grigorian, Gene C. Hilton, Johannes Hubmayr, Galen C. O'Neil, John A. Mates, Kelsey M. Morgan, Daniel R. Schmidt, Robert W. Stevens, Daniel S. Swetz, Leila R. Vale, Joel N. Ullom, Kent D. Irwin, Saptarshi Chaudhuri, Charles J. Titus, Carl S. Dawson
The successful realization and broad deployment of transition edge sensor (TES)-based detector systems has led to significant demand for time-division and code-division superconducting quantum interference device (SQUID) multiplexers time division

Label-Free Detection of Conformational Changes in Switchable DNA Nanostructures with Microwave Microfluidics

March 12, 2019
Author(s)
Angela C. Stelson, Minghui Lu, Charles A. Little, Christian J. Long, Nathan D. Orloff, Nicolas Stephanopolous, James C. Booth
Detection of conformational changes in biomolecular assemblies provides critical information into biological and self-assembly processes. State-of-the-art in situ conformation detection techniques rely on fluorescent labels or protein-specific binding

Magnetoelastic effects in doubly clamped electroplated CoFe micro-beam resonators

March 12, 2019
Author(s)
Margo Staruch, S. P. Bennett, B. R. Matis, J. W. Baldwin, K. Bussmann, Daniel Gopman, Yury Kabanov, June W. Lau, Robert D. Shull, E. Langlois, C. Arrington, J. R. Pillars, Peter Finkel
Magnetostrictive Co77Fe23 films were fabricated on silicon wafers and fully suspended to produce free-standing, doubly clamped, micro-beam resonators. A negative or positive shift in the resonant frequency was observed for magnetic fields applied parallel

Reference Correlations for the Viscosity of 13 Inorganic Molten Salts

March 12, 2019
Author(s)
K.A. Tasidou, Ch. D. Chliatzou, Marc J. Assael, K.D. Antoniadis, Sofia K. Mylona, Marcia L. Huber, William A. Wakeham
In 1988, reference correlations for the viscosity of a selection of molten inorganic salts were proposed by Janz and have been used extensively. During the last 31 years, many additional measurements have been published. In a very recent paper, new

Best practices for benchmarking germline small-variant calls in human genomes

March 11, 2019
Author(s)
Justin M. Zook, Marc L. Salit
Standardized benchmarking approaches are required to assess the accuracy of variants called from sequence data. Although variant- calling tools and the metrics used to assess their performance continue to improve, important challenges remain. Here, as part

Broadband Lamb shift in an engineered quantum system

March 11, 2019
Author(s)
Matti Silveri, S Masuda, Vasilii Sevriuk, K-Y Tan, Mate Jenei, Eric Hyyppa, Fabian Hassler, Matti Partanen, Jan Goetz, Russell Lake, Leif Gronberg, Mikko Mottonen
The shift of the energy levels of a quantum system owing to broadband electromagnetic vacuum fluctuations-the Lamb shift-has been central for the development of quantum electrodynamics and for the understanding of atomic spectra. Identifying the origin of

Cognitive Biases Within Decision Making During Fire Evacuations

March 8, 2019
Author(s)
Michael Kinsey, Steve Gwynne, Erica D. Kuligowski, Max Kinateder
During a fire evacuation, once an individual perceives cues from a fire event, they must interpret them to assess the new situation and determine whether action is required. It is proposed that this assessment and action selection can employ either an

Induced Current Effects in Josephson Voltage Standard Circuits

March 8, 2019
Author(s)
Anna E. Fox, Grace E. Butler, Miranda L. Thompson, Paul D. Dresselhaus, Samuel P. Benz
A study has been performed to understand the effects of magnetic field induced current in Josephson voltage standard circuits. Inductive filtering is an essential component in Josephson voltage standard devices for isolation of the microwave and DC bias

Spinon Confinement and a Sharp Longitudinal Mode in Yb 2 Pt 2 Pb in Magnetic Fields

March 8, 2019
Author(s)
W. J. Gannon, I. A. Zaliznyak, L. S. Wu, A. E. Feiguin, A. M. Tsvelik, F. Demmel, Yiming Qiu, John R. Copley, M. S. Kim, M. C. Aronson
The fundamental excitation of spin chain systems is the spinon, which is a deconfined quasiparticle with fractionalized spin. Coupling spin chains leads to the confinement of these spinons, a condensed matter analog of quark confinement in quantum
