We report on the first earth-scale quantum sensor network based on optical atomic clocks aimed at dark matter (DM) detection. Exploiting differences in the susceptibilities to the fine- structure constant of essential parts of an optical atomic clock, i.e

Understanding Material Characteristics through Signature Traits from He Pycnometry

January 30, 2019
Author(s)
Huong Giang T. Nguyen, Jarod C. Horn, Matthew Bleakney, Daniel W. Siderius, Laura Espinal
Although helium pycnometry is generally the method of choice for skeletal density measurements of porous materials, few studies have provided a wide range of case studies that demonstrate how to best interpret raw data and perform measurements using it

January 28, 2019
Author(s)
Darwin R. Reyes-Hernandez, Henne van Heeren
In the last two decades, the microfluidics/lab-on-a-chip field has evolved from the concept of micro total analysis systems, where systems with integrated pretreatment and analysis of chemicals were envisioned, to what is known today as lab-on-a-chip

Rethinking Timekeeping for Modern IT Solutions

Author(s)
Son VoBa, Charles L. Ulland, Michael Lombardi, Arno Lentfer
Advances in processor performance and virtualization technologies, together with complexities of operating systems (OS) and software defined networking, have outpaced legacy network-based solutions for keeping system clocks accurate across geographic

Upstream vortex and elastic wave in the viscoelastic flow around a confined cylinder

January 28, 2019
Author(s)
Boyang Qin, Paul Salipante, Steven Hudson, Paulo E. Arratia
The viscoelastic flow past cylinder is a classic benchmark problem that is not completely understood. Using novel holographic particle velocimetry, we report two main discoveries of the elastic instability upstream of a single cylinder in confined channel

The quantum Zeno paradox, 42 years on

January 25, 2019
Author(s)
Wayne M. Itano
The term 'quantum Zeno paradox' or 'quantum Zeno effect' refers to the slowing down of the evolution of a quantum system as it is observed more and more frequently. In 1977, Misra and Sudarshan gave a theoretical demonstration of its existence. There has

A Method Level Test Generation Framework for Debugging Big Data Applications
