Single photon lidar (SPL) systems have great potential to be an effective tool for mapping due to their high data collection efficiency.  ...  Herein, a novel voxel-spherical adaptive ellipsoid searching (VSAES) method is proposed, by which weak signal returns can be successfully retained while still removing a majority of the noise points.  ...  It was also demonstrated with coincident LML data that points from thin powerlines, which are not recorded in the LML data, can be detected from SPL data, even though the SPL system was flown at a higher  ...

Much of what we know about neutrinos comes from studying neutrino flavour oscillations, whereby one type of neutrino transforms into a different type as it propagates over a large distance.  ...  However, these �ghostly� particles are incredibly difficult to detect, mostly passing freely through matter.  ...  X-ray photon) individually. Especially the Timepix3 detector, which is optimized for this mode, provides very complete information for every detected particle.  ...
