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 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...
We analyze several pulse-height analysis schemes aimed at realizing maximum precision with TES (transition-edge sensor) microcalorimeter x-ray detectors. Issues...
In this paper, we present a ray tracing (RT) assisted multipath cluster association method. This work is based on an indoor channel measurement at 60 GHz, where...
