Electronics Supply Chain Integrity Enabled by Blockchain

June 1, 2019
Author(s)
Xiaolin Xu, Fahim Rahman, Bicky Shakya, Apostol Vassilev, Domenic Forte, Mark Tehranipoor
Electronic systems are ubiquitous today, playing an irreplaceable role in our personal lives as well as in critical infrastructures such as power grid, satellite communication, and public transportation. In the past few decades, the security of software

Fracture Mechanics Approach to Splitting in Low Spring Index Cold Coiling Process

June 1, 2019
Author(s)
Y. Prawoto, S. Manville, T. Sakai, L. Lee, M. Tanaka, Thomas H. Gnaupel-Herold
This paper is an attempt to understand the coil splitting phenomena by means of fracture mechanics. The methods used combines the residual stress measurement with neutron and finite element analysis. The support of the metallurgical evaluation is used as

Large-Signal Network Analysis for Over-the-Air Test of Up-Converting and Down-Converting Phased Arrays

June 1, 2019
Author(s)
Alec Weiss, Dylan Williams, Jeanne Quimby, Rod Leonhardt, Thomas Choi, Zihang Chen, Kate Remley, andreas Molisch, Ben Jamroz, Jake Rezac, Peter Vouras
We explore large-signal network analysis for the over-the-air test of up-converting and down-converting phased arrays. The approach first uses a vector network analyzer to calibrate the impulse response of an over-the-air test system at RF. The vector

Coexistence of Ferromagnetic and Stripe-Type Antiferromagnetic Spin Fluctuations in YFe 2 Ge 2

May 31, 2019
Author(s)
Hongliang Wo, Qisi Wang, Yao Shen, Xiaowen Zhang, Yiqing Hao, Yu Feng, Shoudong Shen, Zheng He, Bingying Pan, Wenbin Wang, K. Nakajima, S. Ohira-Kawamura, P. Steffens, M. Boehm, K. Schmalzl, T. R. Forrest, M. Matsuda, Yang Zhao, Jeffrey W. Lynn, Zhiping Yin, Jun Zhao
We report neutron scattering measurments of single-crystalline YFe 2Ge 2 in the normal state, which has the same crystal structure to the 122 family of iron pnictide superconductors. YFe 2Ge 2 does not exhibit long range magnetic order, but exhibits strong

Quantum gate teleportation between separated zones of a trapped-ion processor

May 31, 2019
Author(s)
Yong Wan, Daniel Kienzler, Stephen D. Erickson, Karl H. Mayer, Ting R. Tan, Jenny J. Wu, Hilma H. Macedo De Vasconcelos, Scott C. Glancy, Emanuel H. Knill, David J. Wineland, Andrew C. Wilson, Dietrich G. Leibfried
Large-scale quantum computers will inevitably require quantum gate operations between widely separated qubits, even within a single quantum information processing device. Nearly two decades ago, Gottesman and Chuang proposed a method for implementing such

Report for Dedicated JPSS VIIRS Ocean Color Calibration/Validation Cruise May 2018

May 31, 2019
Author(s)
Michael Ondrusek, Veronica P. Lance, Menghua Wang, Eric Stengel, Charles Kovach, Robert Arnone, Sherwin Ladner, Wesley Goode, Ahmed El-Habashi, Carlos Carrizo, Eder Herrera, Sam Ahmed, Joaquim I. Goes, Helga de Rosario Gomes, Kali McKee, Chuanmin Hu, Jennifer Cannizzaro, Yingjun Zhang, Chih-Wei Huang, David English, B. Carol Johnson, Zhongping Lee, Xiaolong Yu, Zhehai Shang, Nicholas Tufillaro, Ivan Lalovic, Kenneth Voss
The overall aim of the annual National Oceanic and Atmospheric Administration (NOAA) dedicated Joint Polar Satellite System (JPSS) Visible Infrared Imaging Radiometer Suite (VIIRS) ocean color calibration/validation cruises is to support improvements in

Structure and Function in Antimicrobial Piscidins: Histidine Position, Directionality of Membrane Insertion, and pH-Dependent Permeabilization

May 30, 2019
Author(s)
Mihaela Mihailescu, Mirco Sorci, Jolita Seckute, Vitalii I. Silin, Janet Hammer, B. Scott Perrin, Jorge Hernandez, Nedzada Smajic, Akritee Shrestha, Kimberly Bogadardus, Alexander Greenwood, Riqiang Fu, Jack Blazyk, Richard W. Pastor, Linda Nicholson, Georges Belfort, Myriam Cotten
Piscidins are histidine-enriched antimicrobial peptides that interact with lipid bilayers as amphipathic alpha-helices. Their activity at acidic and basic pH in vivo makes them promising templates for biomedical applications. This study focuses on p1 and
