Heterogeneous integration for on-chip quantum photonic circuits with single quantum dot devices

October 12, 2017
Author(s)
Marcelo I. Davanco, Liu Jin, Luca Sapienza, Chen-Zhao Zhang, Jose Vinicius De Miranda Cardoso, Varun B. Verma, Richard P. Mirin, Sae Woo Nam, Liu Liu, Kartik A. Srinivasan
Photonic integration is establishing itself as an enabling technology for photonic quantum science, offering considerably greater scalability, stability, and functionality than traditional bulk optics. Here, we develop a scalable, heterogeneous III-V /

Likelihood Ratio as Weight of Forensic Evidence: A Closer Look

October 12, 2017
Author(s)
Hariharan K. Iyer, Steven P. Lund
The forensic science community has increasingly sought quantitative methods for conveying the weight of evidence. Experts from many forensic laboratories summarize their fndings in terms of a likelihood ratio. Several proponents of this approach have

Proceedings of the 2017 Model-Based Enterprise (MBE) Summit

October 12, 2017
Author(s)
Thomas D. Hedberg, Mark G. Carlisle
On April 3-6, 2017, the National Institute of Standards and Technology (NIST) hosted the Model- Based Enterprise (MBE) Summit to identify challenges, research, implementation issues, and les- sons learned in manufacturing and quality assurance where a

Local Breaking of Fourfold Rotational Symmetry by Short-Range Magnetic Order in Heavily Overdoped Ba(Fe 1-x Cu x ) 2 As 2

October 11, 2017
Author(s)
Weiyi Wang, Yu Song, Ding Hu, Yu Li, Rui Zhang, Leland Harriger, Wei Tian, Huibo Cao, Pengcheng Dai
We investigate Cu-doped Ba(Fe 1-xCu x) 2As 2 with transport, magnetic susceptibility, and elastic neutron scattering measurements. In the heavily Cu-doped regime where long-range stripe-type antiferromagnetic order in BaFe 2As 2 is suppressed, Ba(Fe 1-xCu

Microwave SQUID Multiplexer for Cosmic Microwave Background Imagers

October 11, 2017
Author(s)
Bradley J. Dober, Daniel T. Becker, Douglas A. Bennett, Sean A. Bryan, Shannon M. Duff, Johnathon D. Gard, James P. Hays-Wehle, Johannes Hubmayr, John A. Mates, Carl D. Reintsema, Leila R. Vale
Key performance characteristics are demonstrated for the microwave SQUID multiplexer (µmux) coupled to transition edge sensor (TES) bolometers that have been optimized for cosmic microwave background (CMB) observations. In a 64-channel demonstration, we

Structural, Chemical, and Dynamical Frustration: Origins of Superionic Conductivity in closo-Borate Solid Electrolytes

October 11, 2017
Author(s)
Kyoung E. Kweon, Joel B. Varley, Patrick Shea, Nicole Adelstein, Prateek Mehta, Tae Wook Heo, Terrence J. Udovic, Vitalie Stavila, Brandon C. Wood
Li 2B 12H 12 and Na 2B^12^H 12 closoboranes exhibit unusually high ionic conductivity, making them attractive as a new class of candidate electrolytes in solid-state Li- and Na-ion batteries. However, further optimization of these materials requires a

Sucrose density gradient centrifugation for efficient separation of engineered nanoparticles from a model organism, Caenorhabditis elegans

October 11, 2017
Author(s)
Monique E. Johnson, Antonio R. Montoro Bustos, Elijah J. Petersen, Shannon K. Hanna, Karen E. Murphy, Lee L. Yu, Bryant C. Nelson, Michael R. Winchester
This protocol describes a strategy for separating Caenorhabditis elegans (C. elegans) from engineered nanomaterials, a critical step for accurate quantification in uptake studies. Conventional rinsing procedures, typically comprised of water or buffer
