Factors determining spectral width of HF echoes from high latitudes [PDF]
Annales Geophysicae, 2007 Spectral width is one of the standard data types produced by the Super Dual Auroral Radar Network (SuperDARN). A pronounced latitudinal gradient in spectral width has been reported in the literature and is used as an empirical proxy for the ...

A coded-aperture technique allowing x-ray phase contrast imaging with conventional sources [PDF]
, 2007 Phase contrast imaging (PCI) solves the basic limitation of x-ray imaging, i.e., poor image contrast resulting from small absorption differences. Up to now, it has been mostly limited to synchrotron radiation facilities, due to the stringent requirements

Modeling Approaches for Gain, Noise and Time Response of Avalanche Photodiodes for X-Rays Detection
Frontiers in Physics, 2022 We report on a suite of modeling approaches for the optimization of Avalanche Photodiodes for X-rays detection. Gain and excess noise are computed efficiently using a non-local/history dependent model that has been validated against full-band Monte Carlo

Neuroimaging in Menkes disease
Journal of Pediatric Neurosciences, 2017 Menkes disease (MD) is a rare infantile onset neurodegenerative disorder due to mutations in the X linked ATP7A gene. These patients can present with failure to thrive, severe psychomotor retardation, seizures and hypopigmented hair, which is characteristic of this condition. A number of neuro-radiological findings have been reported in this condition.
