Quantum limitations of the signals distinqvishability

Физика волновых процессов и радиотехнические системы, 2013
From the corpuscular understanding of radio waves it follows that small enough location signals are discrete and may disappear completely. Maximum location distance has, therefore, the fundamental limitations, not depending on the noise level.

Scintillation-induced variability in radio absorption spectra against extragalactic sources

, 2005
Spectral features absorbed against some radio quasars exhibit ~50 mJy variations, with the lines varying both relative to the continuum and, when several lines are present, even relative to one another.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...
