LidPose: Real-Time 3D Human Pose Estimation in Sparse Lidar Point Clouds with Non-Repetitive Circular Scanning Pattern.

In this paper, we propose a novel, vision-transformer-based end-to-end pose estimation method, LidPose, for real-time human skeleton estimation in non-repetitive circular scanning (NRCS) lidar point clouds. Building on the ViTPose architecture, we introduce novel adaptations to address the unique properties of NRCS lidars, namely, the sparsity and unusual rosetta-like scanning pattern. The proposed method addresses a common issue of NRCS lidar-based perception, namely, the sparsity of the measurement, which needs balancing between the spatial and temporal resolution of the recorded data for efficient analysis of various phenomena.

The use of a remote-controlled minivalve, carried by freely moving animals on their head, to achieve instant pharmacological effects in intracerebral drug-perfusion studies.

Intracerebral drug-perfusion studies in animals can be very efficiently performed with the 'reverse-dialysis' procedure. In this procedure, drugs are delivered into the brain via an intracerebrally implanted microdialysis probe. Traditionally, in reverse-dialysis studies the flow of control and drug solutions in the microdialysis site is alternated by large and heavy valves placed far from the experimental animal.
