Symmetry-breaking inelastic wave-mixing atomic magnetometry

December 1, 2017
Author(s)
Feng Zhou, Edward W. Hagley, Lu Deng, Chengjie Zhu
The nonlinear magneto-optical rotation (NMOR) effect has prolific applications ranging from precision mapping of Earth's magnetic field to biomagnetic sensing. Studies on collisional spin relaxation effects have led to ultrahigh magnetic field

The Future of Quantum Based Measurements and the SI

December 1, 2017
Author(s)
Carl J. Williams
The U.S. National Institute of Standards and Technology (NIST), along with other NMIs, is preparing for a new era in the history of metrology made possible by the growing use of quantum-based standards and measurements. This development will dramatically

The SI and Quantum Metrology

December 1, 2017
Author(s)
Carl J. Williams
The United States’ National Institute of Standards and Technology (NIST) is playing a major role in the worldwide effort to base the International System of Units (SI) on fundamental constants. In many cases, units will be redefined in terms of invariant

Throughput Study for Channel Bonding in IEEE 802.11ac Networks

December 1, 2017
Author(s)
Munsuk Kim, Tanguy Ropitault, SuKyoung Lee, Nada T. Golmie
Several analytical models for the channel bonding feature of IEEE 802.11ac have been presented for performance estimation. However, the accuracy of such models is limited by the assumptions that there are no collisions or all nodes are in saturated state

Tissue Inhibitor of Metalloprotease-2: bioprocess development, physicochemical, biochemical and biological characterization of highly expressed recombinant protein

December 1, 2017
Author(s)
Ananda Chowdhury, Robert G. Brinson, Beiyang Wei, William G. Stetler-Stevenson
Tissue Inhibitor of Metalloprotease -2 (TIMP-2) is a secreted, 21 kDa, multifunctional protein. It was first described as an endogenous inhibitor of matrix metalloproteases (MMPs) that prevents protease-mediated breakdown of the extracellular matrix often

WIND LOAD FACTORS FOR USE IN THE WIND TUNNEL PROCEDURE

December 1, 2017
Author(s)
Emil Simiu, Adam L. Pintar, Dat Duthinh, DongHun Yeo
A 2005 Skidmore Owings and Merrill report notes that the ASCE 7 Standard is incomplete insofar as it provides no guidance on wind load factors appropriate for use with the Standard’s wind tunnel procedure. The purpose of this paper is to contribute to such

Attribute Based Access Control

November 30, 2017
Author(s)
Chung Tong Hu, David F. Ferraiolo, Ramaswamy Chandramouli, David R. Kuhn
Until now, ABAC research has been documented in hundreds of research papers, but not consolidated in book form. This book explains ABAC's history and model, related standards, verification and assurance, applications, and deployment challenges; Specialized
