Using paleoclimate reconstructions to analyse hydrological epochs associated with Pacific decadal variability [PDF]

open access: yesHydrology and Earth System Sciences, 2018
The duration of dry or wet hydrological epochs (run lengths) associated with positive or negative Inter-decadal Pacific Oscillation (IPO) or Pacific Decadal Oscillation (PDO) phases, termed Pacific decadal variability (PDV), is an essential statistical ...

Point Density-Aware Voxels for LiDAR 3D Object Detection [PDF]

open access: yesComputer Vision and Pattern Recognition, 2022
LiDAR has become one of the primary 3D object detection sensors in autonomous driving. However, LiDAR's diverging point pattern with increasing distance results in a non-uniform sampled point cloud ill-suited to discretized volumetric feature extraction.

Measuring detonation wave profiles in plastic-bonded explosives using PDV

open access: yesAIP Advances, 2019
To obtain reaction zone parameters for several high explosives, experimental measurements of the detonation wave profiles in HMX-, RDX- and PETN-based explosives were performed using photon Doppler velocimetry (PDV).

Development of RT-PCR tests for the routine detection of latent and ILAR viruses in fruit trees

open access: yesPlant Protection Science, 2002
The detection throughout the year of latent and ILAR viruses in fruit trees by classical serological tests appears to be unreliable. Recently, these problems have smoothed themselves out by the use of molecular methods. We have developed RT-PCR protocols
