Experimental low-speed positioning system with VecTwin rudder for automatic docking (berthing)

open access: yesJournal of Marine Science and Technology, 2023
A VecTwin rudder system comprises twin fishtail rudders with reaction fins to increase its performance. With a constant propeller revolution number, the vessel can execute special low-speed maneuvers like hover, crabbing, reverse, and rotation. Such low-speed maneuvers are termed dynamic positioning (DP), and a DP vessel should be fully/overly actuated

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 10, Page 2895-2908, October 2026.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...

Comparative Analysis of Four Matrix Dilution Methods for Eliminating IgM Paraprotein Interference in Prealbumin and Uric Acid Assays: Based on Two Case Reports

open access: yesJournal of Clinical Laboratory Analysis, Volume 40, Issue 9, May 2026.
IgM paraproteins can cause significant interference in prealbumin (PA) and uric acid (UA) measurements, leading to falsely abnormal results. We systematically compared four dilution methods to eliminate this interference. Dilution with the PA reagent (containing PEG) effectively restored accurate PA results.
