Murugiah P. Souppaya, William A. Haag Jr., Mehwish Akram, William C. Barker, Rob Clatterbuck, Brandon Everhart, Brian Johnson, Alexandros Kapasouris, Dung Lam, Brett Pleasant, Mary Raguso, Susan Symington, Paul Turner, Clint Wilson, Donna F. Dodson
Transport Layer Security (TLS) server certificates are critical to the security of both internet- facing and private web services. Despite the critical importance of these certificates, many organizations lack a formal TLS certificate management program

Superconducting microwire detectors with single-photon sensitivity in the near-infrared

June 16, 2020
Author(s)
Jeffrey T. Chiles, Sonia M. Buckley, Adriana E. Lita, Varun B. Verma, Jeffrey M. Shainline, Richard P. Mirin, Sae Woo Nam, Jason Allmaras, Boris Korzh, Emma Wollman, Matthew Shaw
We report on the fabrication and characterization of single-photon-sensitive WSi superconducting detectors with wire widths from 1 υm to 3 υm. The devices achieve saturated internal detection efficiency at 1.55 υm wavelength and exhibit maximum count rates

A robust benchmark for detection of germline large deletions and insertions

June 15, 2020
Author(s)
Justin Zook, Nathanael David Olson, Marc Salit, Fritz Sedlazeck
New technologies and analysis methods are enabling genomic structural variants (SVs) to be detected with ever-increasing accuracy, resolution and comprehensiveness. To help translate these methods to routine research and clinical practice, we developed a

Effect of Pressure on the Heat Transfer of Pool Fire in a Closed Chamber

June 15, 2020
Author(s)
Jian Chen, Yubo Bi, Yanli Zhao, Andy Tam, Changhai Li, Shouxiang Lu
A combined analytical and experimental study was performed to determine the effect of pressure on the heat transfer of pool fire in a closed chamber. A series of ethanol pool fires with diameters from 4 cm to 10 cm were carried out in the pressure chamber

Electron-electron interactions in low-dimensional Si:P delta layers

June 15, 2020
Author(s)
Joseph Hagmann, Xiqiao Wang, Ranjit Kashid, Pradeep Namboodiri, Jonathan Wyrick, Scott W. Schmucker, Michael Stewart, Richard M. Silver, Curt A. Richter
Key to producing quantum computing devices based on the atomistic placement of dopants in silicon by scanning tunneling microscope (STM) lithography is the formation of embedded highly doped Si:P delta layers (δ-layers). This study investigates the

Manipulation of Coupling and Magnon Transport in Magnetic Metal-Insulator Hybrid Structures

June 15, 2020
Author(s)
Yabin Fan, Patrick Quarterman, Joseph Finley, Jiahao Han, Pengxiang Zhang, Justin T. Hou, Mark D. Stiles, Alexander Grutter, Luqiao Liu
Ferromagnetic metals and insulators are widely used for generation, control and detection of magnon spin signals. Most magnonic structures are based primarily on either magnetic insulators or ferromagnetic metals, while heterostructures integrating both of

Modern reassessment of the Citicorp Building design wind loads

June 15, 2020
Author(s)
Dat Duthinh
Following structural engineering practice of the 1970s, engineers designed the Citicorp Building for the action of wind in each of the structure’s principal axes. One problem they faced was how to determine design values by combining simultaneous wind

Quantum-enhanced interferometry with large heralded photon-number states

June 14, 2020
Author(s)
G Thekkadath, M.E. Mycroft, B.A. Bell, C.G. Wade, A. Eckstein, David Phillips, R.B Patel, A. Buraczewski, Adriana Lita, Thomas Gerrits, Sae Woo Nam, M. Stobinska, A.I. Lvovsky, Ian Walmsley
Quantum phenomena such as entanglement can improve fundamental limits on the sensitivity of a measurement probe. In optical interferometry, a probe consisting of N entangled photons provides up to a sqrt(N) enhancement in phase sensitivity compared to a

Structural, Magnetic, and Electronic Evolution of the Spin-Ladder System BaFe 2 S 3-x Se x with Isoelectronic Substitution

June 12, 2020
Author(s)
Jia Yu, Meng Wang, Benjamin A. Frandsen, Hualei Sun, Junjie Yin, Zengjia Liu, Shan Wu, Ming Yi, Zhijun Xu, Arani Acharya, Qingzhen Huang, Edith Bourret-Courchesne, Jeffrey W. Lynn, Robert J. Birgeneau
We report experimental studies of a series of BaFe 2S 3-xSe x (0less than or equal to}xless than or equal to}3) single crystals and powder specimens using x-ray diffraction, neutron diffraction, muon spin relaxation, and electrical transport measurements

Theory of Discrete Event Logistics Systems (DELS) Specification

June 12, 2020
Author(s)
Timothy A. Sprock, George Thiers, Leon F. McGinnis, Conrad E. Bock
System models and model-based engineering methods have the promise of transforming the way that industrial engineers interact with production and logistics systems. Model-based methods play a role in improving communication between stakeholders

Blind Calibration of Phase Drift in Millimeter-Wave Channel Sounders

June 11, 2020
Author(s)
Jack Chuang, Jelena Senic, Chunmei Liu, Camillo Gentile, Sung Yun Jun, Derek Caudill
Millimeter-wave channel sounders are much more sensitive to phase drift than their microwave counterparts by virtue of shorter wavelength. This matters when coherently phasing (electronic or mechanical) antenna scans collected over seconds, minutes, or

Ferromagnetism in van der Waals Compound MnSb 1.8 Bi 0.2 Te 4
