Chemiresistive microsensor arrays are being developed and tested in a simulated Martian environment. Target analyte species include trace small molecules that...
Cross-spectral analysis is a mathematical tool for extracting the power spectral density of a correlated signal from two time series in the presence of...
Polar coding is the most recent encoding scheme in the quest for error correction codes that approaches the Shannon limit, has a simple structure, and admits...

A compact cold-atom clock based on coherent population trapping (CPT) has been developed. The clock typically demonstrates a short-term fractional frequency...
We discuss techniques for measuring the correlation between phase modulated (PM) and amplitude modulated (AM) noise in an oscillator and report results of such...
The need for traceable power measurements above 110 GHz is well established for use in communications, spectral line investigation, molecular particle signature...
We examined the electromagnetic (EM) emissions of three commercially available systems that charge remote devices by use of inductive wireless power transfer...

Current overshoot during forming has been shown to be a serious issue. Recently the current overshoot duration has been shown to be an important factor...
Based on three dimensional (3D) topography measurements on correlation cells, the National Institute of Standards and Technology (NIST) has developed the "NIST...
Constructing an efficient and accurate model from security events to determine an attack scenario for an enterprise network is challenging. In this paper, we...
Two national metrology laboratories (NMI) have conducted an international interlaboratory comparison on thermal conductivity on two thermal insulation reference...
