Scintillations And Microlensing [PDF]
Symposium - International Astronomical Union, 1996 It is shown how the theory of scintillation may be applied to treat gravitational lensing. The theory is applied to microlensing by a system of N point masses. It is shown that scintillation theory reproduces a known result for the angular broadening due to multiple microlensing.

Development of Nd-Doped CaWO4 Single Crystalline Scintillators Emitting Near-Infrared Light
Applied Sciences, 2022 Nd-doped CaWO4 single crystals with dopant concentrations of 0.1, 0.5, and 1% were synthesized by the floating zone method. The transmission, photoluminescence, and scintillation properties were evaluated from ultraviolet to near-infrared (NIR) ranges ...

Drones and global navigation satellite systems: current evidence from polar scientists [PDF]
Royal Society Open Science, 2020 Aerial unmanned vehicles, so-called drones, present a paradigm shift away from the long-term use by scientists of manned aeroplanes and helicopters. This is evident from the number of research articles that focus on data obtained with drones.

Inorganic scintillating materials and scintillation detectors
Proceedings of the Japan Academy, Series B, 2018 Scintillation materials and detectors that are used in many applications, such as medical imaging, security, oil-logging, high energy physics and non-destructive inspection, are reviewed. The fundamental physics understood today is explained, and common scintillators and scintillation detectors are introduced.
