A Preliminary Study of RF Propagation for High Data Rate Brain Telemetry

February 11, 2022
Author(s)
Mariella Sarestoniemi, Carlos Pomalaza-Raez, Kamran Sayrafian, Teemu Myllyla, Jari Iinatti
This paper presents the preliminary results of a study on the radio frequency (RF) propagation inside the human skull at several Industrial, Scientific and Medical (ISM) and ultrawideband UWB frequencies. These frequency bands are considered as possible

Synthesis, crystal structure, and physical properties of BaSnS2

February 11, 2022
Author(s)
Wilarachchige Gunatilleke, Andrew May, Angela R. Hight Walker, Adam Biacchi, George Nolas
Phase-pure BaSnS2, with space group Pn21/c, was synthesized and the structural and physical properties were investigated. The thermal properties and optical measurements are reported for the first time. The Debye temperature and Sommerfeld coefficient were

Certification of NIST Gas Mixture Standard Reference Materials

February 10, 2022
Author(s)
Christina Cecelski, Kimberly Harris, Cassie Goodman, William A. Kimes, Philip Liu, Walter R. Miller Jr., Jennifer Carney
The Gas Sensing Metrology Group at NIST provides accurate, stable gaseous standards for use in various types of emissions testing and environmental monitoring. The group develops and maintains the highest level of primary gas standards, which provide

Empirical Differences in LTE Open- and Closed-Loop Power Control

February 10, 2022
Author(s)
Azizollah Kord
We present the empirical Physical Uplink Shared Channel radiated power of a User Equipment in a commercial Long-Term Evolution Frequency-Division Duplex system in open- and closed-Loop power control. We present new insights, targeted on power control, from

Empirical Differences in LTE Open- and Closed-Loop power Control

February 10, 2022
Author(s)
Azizollah Kord, Jason Coder, Aric Sanders
We present the empirical Physical Uplink Shared Channel (PUSCH) radiated power of a User Equipment (UE) in a commercial Long-Term Evolution (LTE) frequency division duplex system. We measured the radiated PUSCH channel power while varying 28 different

Performance of NIST SRM(R) 2917 with 13 Recreational Water Quality Monitoring qPCR Assays

February 10, 2022
Author(s)
Jessica Willis, Mano Sivaganesan, Richard Haugland, Jason Kralj, Stephanie Servetas, Monique Hunter, Scott Jackson, Orin Shanks
Fecal pollution remains a significant challenge for recreational water quality management worldwide. In response, there is a growing interest in the use of real-time quantitative PCR (qPCR) methods to achieve same-day notification of recreational water

Prioritizing Cybersecurity Risk for Enterprise Risk Management

February 10, 2022
Author(s)
Stephen Quinn, Matthew Barrett, Greg Witte, Robert Gardner, Nahla Ivy
This document is the second in a series that supplements NIST Interagency/Internal Report (NISTIR) 8286, Integrating Cybersecurity and Enterprise Risk Management (ERM). This series provides additional detail regarding the enterprise application of

Experimental observation of thermalisation with noncommuting charges

February 9, 2022
Author(s)
Florian Kranzl, Aleksander Lasek, Manoj Joshi, Amir Kalev, Rainer Blatt, Christian Roos, Nicole Halpern
Quantum simulators have recently enabled experimental observations of quantum many-body systems' internal thermalisation. Often, the global energy and particle number are conserved, and the system is prepared with a well-defined particle number—in a

Head on Comparison of Self- and Nano-Assemblies of Gamma Peptide Nucleic Acid Amphiphiles

February 9, 2022
Author(s)
Shipra Malik, Vikas Kumar, Chung-Hao Liu, Kuo-Chih Shih, Susan T. Krueger, Mu-Ping Neih, Raman Bahal
Peptide nucleic acids (PNAs) are nucleic acid analogs with superior hybridization properties and enzymatic stability than deoxyribonucleic acid (DNA). In addition to gene targeting applications, PNAs have garnered significant attention as bio-polymer due

Micro to nano: multiscale IR analyses reveal zinc soap heterogeneity in a 19th-century painting by Corot

February 9, 2022
Author(s)
Xiao Ma, Georges Pavlidis, Eoghan Dillon, Victoria Beltran, Jeffrey Schwartz, Mathieu Thoury, Ferenc Borondics, Christophe Sandt, Kevin Kjoller, Barbara Berrie, Andrea Centrone
The formation and aggregation of metal carboxylates (metal-soaps) can degrade the appearance and integrity of oil paints and frequently poses a challenge to the conservation of painted works of art. Efforts to understand the root cause of metal-soap

10 GHz Generation with Ultra-Low Phase Noise via the Transfer Oscillator Technique

February 8, 2022
Author(s)
Nicholas Nardelli, Tara Fortier, Marco Pomponio, Esther Baumann, Craig Nelson, Thomas Schibli, Archita Hati
We generate 10 GHz microwave signals using the transfer oscillator technique, which employs digital and RF analog techniques to coherently remove the additive noise from an optical frequency comb. This method permits transfer of the frequency stability and

Curated variation benchmarks for challenging medically relevant autosomal genes

February 7, 2022
Author(s)
Justin Wagner, Nathanael David Olson, Lindsay Harris, Jennifer McDaniel, Fritz Sedlazeck, Chen-Shan Chin, Justin Zook
The repetitive nature and complexity of some medically relevant genes poses a challenge for their accurate analysis in a clinical setting. The Genome in a Bottle Consortium has provided variant benchmark sets, but these exclude nearly 400 medically
