Incorporating an Optical Clock into a Time Scale

January 1, 2018
Author(s)
Jian Yao, Thomas E. Parker, Neil Ashby, Judah Levine
This paper discusses how to build a time scale with an intermittently-operated optical clock. In particular, it gives suggestions on how long and how often to run an optical clock. It also explores the benefits of having an optical clock in a time scale

Latent Fingerprint Value Prediction: Crowd-based Learning

December 31, 2017
Author(s)
Elham Tabassi, Anil K. Jain, Tarang Chugh, Kai Cao, Jiayu Zhou
Latent fingerprints are one of the most crucial sources of evidence in forensic investigations. As such, devel- opment of automatic latent fingerprint recognition systems to quickly and accurately identify the suspects is one of the most pressing problems

Rheological Properties of Jute-Based Cellulose Nanofibers under Different Ionic Conditions

January 1, 2018
Author(s)
Lihong Geng, Ali Naderi, Yimin NMN Mao, Chengbo Zhan, Priyanka Sharma, Xiangfang Peng, Benjamin S. Hsiao
Cellulose nanofibers (CNF) were produced by 2,2,6,6-tetramethylpiperidinyl-1-oxyl (TEMPO) -oxidation and mechanical shearing of jute pulp. The cross section dimension of CNFs was determined by small-angle neuron scattering (SANS), yielding a width of about

The enigmatic vitrification at the ancient hillfort Broborg and its utilization as an analogue for nuclear waste glass.

Jamie L. Weaver, Rolf Sjoblom, Eva Hjarthner-Holdar, Carolyn Pearce, Erik Ogenhall, Mia Englund, John McCloy, David Peeler, Albert Kruger
Although the modern understanding of chemistry dates back only around 300 years, many of the processes and products used today were actually originally developed by ancient people. However, much of such ancient knowledge has been lost, as is the case for

Neuromorphic Computing through Time-Multiplexing with a Spin-Torque Nano-Oscillator

December 31, 2017
Author(s)
Mathieu Riou, Flavio Abreu Araujo, Jacob Torrejon, Sumito Tsunegi, Guru Khalsa, Damien Querlioz, Paolo Bortolotti, Vincent Cros, K. Yakushiji, Akio Fukushima, Hitoshi Kubota, Shinji Yuasa, Mark D. Stiles, Julie Grollier
Fabricating powerful neuromorphic chips the size of a thumb requires miniaturizing both hardware synapses and neurons. The challenge for neurons is to scale them down to submicrometer diameters while maintaining the properties that allow for reliable
