Feature Topic: Enabling Technologies for Smart Internet of Things

September 18, 2018
Author(s)
Hamid Gharavi
This feature topic aims at providing timely and comprehensive overviews of the current state-of-the art in terms of fundamental theoretical innovations and technological advances and towards exploiting smart caching, communications, computing and

Iris Cameras: Standards Relevant for Camera Selection - 2018

September 18, 2018
Author(s)
James R. Matey, George W. Quinn, Patrick J. Grother, Craig I. Watson, Shahram Orandi
This paper is a summary of our current recommendations for iris camera selection. NIST is developing these recommendations in collaboration with the FBI, other US Government entities with interests in the use of iris recognition technology, and the larger

Thermal conductivity of entropy stabilized oxides: approaching the minimum limit in single crystal solid solutions through charge induced atomic-scale disorder

September 17, 2018
Author(s)
Gheorghe Stan, Jeffrey Braun, Christina Rost, Mina Lim, Ashutosh Giri, David Olson, George Kotsonis, Donald Brenner, Jon-Paul Maria, Patrick Hopkins
Manipulating a crystalline material’s configurational entropy though the introduction of unique atomic species can produce novel materials with desirable mechanical and electrical properties. From a thermal transport perspective, large differences between

Structured light in diffuse optical imaging

September 16, 2018
Author(s)
Joseph P. Angelo, Sez-Jade Chen, Marien Ochoa, Ulas Sunar, Sylvain Gioux, Xavier Intes
Diffuse optical imaging probes deep living tissue enabling structural, functional, metabolic, and/or molecular imaging. Recently, thanks to the availability of spatial light modulators, wide-field quantitative diffuse optical techniques have been

Challenges to miniaturizing cold atom technology for deployable vacuum metrology

September 14, 2018
Author(s)
Stephen P. Eckel, Daniel S. Barker, James A. Fedchak, Nikolai N. Klimov, Eric B. Norrgard, Julia K. Scherschligt, Constantinos Makrides, Eite Tiesinga
Cold atoms are excellent metrological tools; they currently realize SI time and, soon, SI pressure in the ultra-high (UHV) and extreme high vacuum (XHV) regimes. The development of primary, vacuum metrology based on cold atoms currently falls under the

Calibration and Analysis of Tactile Sensors as Slip Detectors

September 13, 2018
Author(s)
Karl Van Wyk, Joseph A. Falco
The existence of tactile afferents sensitive to slip-related mechanical transients in the human hand augments the robustness of grasping through secondary force modulation protocols. Despite this knowledge and the fact that tactile-based slip detection has

Transmission Imaging with a Programmable Detector in a Scanning Electron Microscope

September 13, 2018
Author(s)
Benjamin W. Caplins, Jason D. Holm, Robert R. Keller
A new type of angularly selective electron detector for use in a scanning electron microscope is presented. The detector leverages a digital micromirror device (DMD) to take advantage of the benefits of two-dimensional (2D) imaging detectors and high

Fully self-referenced frequency comb consuming 5 Watts of electrical power

September 12, 2018
Author(s)
Paritosh Manurkar, Edgar F. Perez, Daniel D. Hickstein, David R. Carlson, Jeffrey T. Chiles, Daron A. Westly, Esther Baumann, Scott A. Diddams, Nathan R. Newbury, Kartik A. Srinivasan, Scott B. Papp, Ian R. Coddington
We present a hybrid fiber/waveguide design for a 100-MHz frequency comb that is fully self- referenced and temperature controlled with less than 5 W of electrical power. Self-referencing is achieved by supercontinuum generation in a silicon nitride

Monte Carlo Simulation of Cylinders with Short-Range Attractions

September 12, 2018
Author(s)
Harold W. Hatch, Nathan Mahynski, R. P. Murphy, Marco Blanco, Vincent K. Shen
Cylindrical or rod-like particles are promising materials for the applications of fillers in nanocomposite ma- terials and additives to control rheological properties of colloidal suspensions. Recent advances in particle synthesis allows for cylinders to

Polymer Identification of Plastic Debris Ingested by Pelagic-phase Sea Turtles in the Central Pacific

September 12, 2018
Author(s)
Melissa R. Jung, George H. Balazs, Thierry M. Work, T. T. Jones, Sara Orski, Viviana Rodriguez, Kathryn Beers, S. A. Abriola, K. D. Hyrenbach, Brenda A. Jensen, Jennifer Lynch
Pelagic Pacific sea turtles eat large quantities of plastic. We identified the polymers ingested by 37 olive ridley, 9 green and 4 loggerhead sea turtles caught as bycatch in Pacific longline fisheries using Fourier transform infrared spectroscopy
