Precision surveying using very long baseline interferometry [PDF]
Radio interferometry measurements were used to measure the vector baselines between large microwave radio antennas. A 1.24 km baseline in Massachusetts between the 36 meter Haystack Observatory antenna and the 18 meter Westford antenna of Lincoln ...

Selection and Characterization of SARS‐CoV‐2 Spike Binding Clickmers
ChemBioChem, Volume 27, Issue 1, January 2026.Split‐combine click‐systematic evolution of ligands by exponential enrichment against wild‐type SARS‐CoV‐2 spike glycoprotein yields benzofuran‐ and indole‐functionalized DNA aptamers (clickmers). These clickmers retain specific binding to multiple variants with nanomolar affinity, and the 31 nt indole‐functionalized truncate T2 retains binding to ...

Geophysical applications of very-long-baseline interferometry [PDF]
Reviews of Modern Physics, 1991 Very-long-baseline interferometry (VLBI) is a novel observing technique for measuring the relative positions of widely separated points on the surface of the Earth with centimeter-level accuracy. Such accuracy is two or three orders of magnitude better than was available with classical techniques only a few decades ago.

VLBI observations of the most radio-loud, narrow-line quasar SDSS J094857.3+002225 [PDF]
, 2006 We observed the narrow-line quasar SDSS J094857.3+002225, which has the highest known radio loudness for a narrow-line Seyfert~1 galaxy (NLS1), at 1.7--15.4 GHz with the Very Long Baseline Array (VLBA). This is the first very-long-baseline interferometry
