Toward Personalized Theranostics: A Modular PET Platform for Antibody-Based Imaging and Therapy. [PDF]

Adv Sci (Weinh)
This modular, site‐specific antibody platform enables customizable conjugates for PET imaging and therapy. Interchangeable payloads – including radiometals, cytotoxics, and fluorophores – support adaptable, multimodal applications with limited off‐target effects. In vivo, the DFO/DOTAGA bischelate immunoconjugate provided clear tumor delineation in PET/

Demonstration of Ultrawideband Polarimetry Using VLBI Exploration of Radio Astrometry (VERA)

Galaxies, 2022
We report on recent technical developments in the front- and back-ends for the four 20 m radio telescopes of the Japanese Very-Long-Baseline Interferometry (VLBI) project, VLBI Exploration of Radio Astrometry (VERA). We present a brief overview of a dual-

Irregular Layout for a Satellite’s Interferometric Array

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
We address the optimization problem of antenna placement on satellite-mounted interferometric synthetic-aperture instruments. In classic designs, the antennas on satellites are aligned regularly on the satellite’s frame.

Observations of atmospheric gravity waves by radio interferometry: are results biased by the observational technique? [PDF]

Annales Geophysicae, 1997
In this paper we present a quantitative comparison between a large data base of medium-scale atmospheric gravity waves (AGWs) observed by radio interferometry of transionospheric radio sources and the results of a numerical simulation of the observed ...
