In a millimeter-wave modulated-signal measurement system with several calibration reference planes, we want the measured signal to be a close replica of the
In an alternate universe, XML (1998) and XSLT 1.0 (1999) were not developed so early, and did not have to wait for the rest of the web to catch up. In ours, it
X-ray absorption spectroscopies are well-established for the purpose of interrogating the structure about metal sites. Often, these methods also exhibit
We analyze several pulse-height analysis schemes aimed at realizing maximum precision with TES (transition-edge sensor) microcalorimeter x-ray detectors. Issues

We present dual-comb spectroscopy across a 14.5-km path using remote receiver and data acquisition. This configuration results in lower link losses compared to
Fault detection often depends on the specific order of inputs that establish states which eventually lead to a failure. However, beyond basic structural

With growing interest in millimeter-wave (mmWave, 30 GHz – 300 GHz) technologies, researchers and manufacturers need standard reference materials and best
Updates may be one of the few tools consumers have to mitigate security and privacy vulnerabilities in smart home devices. However, little research has been
The National Institute of Standards and Technology (NIST) Center for Neutron Research (NCNR) is one of the primary U.S. national research facilities that hosts
GPSDCs are sensitive to their environment in many ways, and the susceptibility varies with different GPSDC designs. In the short term, temperature shocks can
