March 29, 2016
Author(s)
Matthew Boyd
A weather station has been constructed on the Gaithersburg, Maryland campus of the National Institute of Standards and Technology (NIST) as part of a research effort to assess performance of photovoltaic and building systems. This weather station includes

A strong loophole-free test of local realism

December 16, 2015
Author(s)
Lynden K. Shalm, Evan Meyer-Scott, B. G. Christensen, Peter L. Bierhorst, Michael A. Wayne, Deny Hamel, Martin J. Stevens, Thomas Gerrits, Scott C. Glancy, Michael S. Allman, Kevin J. Coakley, Shellee D. Dyer, Adriana E. Lita, Varun B. Verma, Joshua C. Bienfang, Alan L. Migdall, Yanbao Zhang, William Farr, Francesco Marsili, Matthew D. Shaw, Jeffrey Stern, Carlos Abellan, Waldimar Amaya, Valerio Pruneri, Thomas Jennewein, Morgan Mitchell, P. G. Kwiat, Richard P. Mirin, Emanuel H. Knill, Sae Woo Nam
We present a loophole-free violation of local realism using entangled photon pairs. We ensure that all relevant events in our Bell test are spacelike separated by placing the parties far enough apart and by using fast random number generators and high

Software-defined Radio Based Measurement Platform for Wireless Networks

October 15, 2015
Author(s)
I-Chun Chao, Kang B. Lee, Rick Candell, Frederick M. Proctor, Chien-Chung Shen
There has been a dramatic push to adopting wireless networking technologies and protocols (such as 802.11, ZigBee, WirelessHART, Bluetooth, ISA100.11a, etc.) into time-critical networks. End-to-end latency is critical to many distributed applications and

Understanding Small-Molecule Interactions in Metal-Organic Frameworks: Coupling Experiment with Theory

Universal scaling law for the flow of non-Newtonian colloidal suspension

October 1, 2014
Author(s)
Nicos Martys, William L. George, Maxime Liard, Pascal Hebraud, Didier Lootens
It has been observed that flow curves (viscosity vs shear-rate) of spherical non-colloidal particles suspended in a non-Newtonian fluid matrix can be rescaled so as to collapse onto the flow curve of the matrix fluid. This result is surprising given the
