Primordial Black Holes in Phantom Cosmology [PDF]
, 2009 We investigate the effects of accretion of phantom energy onto primordial black holes. Since Hawking radiation and phantom energy accretion contribute to a {\it decrease} of the mass of the black hole, the primordial black hole that would be expected to ...

A Formula to Calculate the Threshold for Radiotherapy Targets on PET Images: Simulation Study
Frontiers in Oncology, 2020 BackgroundPositron emission tomography (PET) images are being applied for defining radiotherapy targets. However, a recognized method for defining radiotherapy targets is lacking. We investigate the threshold to outline the radiotherapy target of a tumor
