TECHNICAL NOTE: FLOW VELOCITY AND DISCHARGE MEASUREMENT IN RIVERS USING TERRESTRIAL AND UNMANNED-AERIAL-VEHICLE IMAGERY

Technical Note: Flow velocity and discharge measurement in rivers using terrestrial and unmanned-aerial-vehicle imagery

An automatic workflow to measure surface flow velocities in rivers is introduced, including a Python tool.The method is based on particle-tracking velocimetry (PTV) and comprises an automatic definition of the search area for particles to track.Tracking is performed in the original images.Only the final tracks are geo-referenced, intersecting the i

Death from Liver Failure despite Lamivudine Prophylaxis during R-CHOP Chemotherapy due to Rapid Emergence M204 Mutations

Background.Rapid and early emergence of clinically significant LAM resistance is thought to be unlikely during the first year of treatment, and as a result LAM is thought to be a reasonable choice as a first line agent for prophylaxis during chemotherapy.Aim.To report fatal HBV reactivation despite appropriate LAM prophylaxis in two previously trea

Sneaky tactics: Ingenious immune evasion mechanisms of Bartonella

ABSTRACTGram-negative Bartonella species are facultative intracellular bacteria that can survive in the harsh intracellular milieu of host cells.They have evolved strategies to evade detection and degradation by the host immune system, which ensures their proliferation in the host.Following infection, Bartonella alters the initial immunogenic flexc

Arthroscopic Guided Synovial Biopsies

Synovial tissue can be safely and reliably collected for research and clinical purposes using arthroscopy.This technique offers the obvious advantage of allowing direct visualization, and targeted biopsy of specific areas of interest within the joint, as well as for the collection of tissue which will include a lining layer.Much has been learnt ala
