ABSTRACT In plasma medicine and biological applications, plasmas typically deliver a complex combination of reactive chemical species and multiple physical energy components. However, establishing a unified and comparable dose metric to characterise their integrated biological effects remains a major challenge that continues to limit progress in this ...

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Coupling Dynamics Study on Multi-Body Separation Process of Underwater Vehicles
Based on the Newton-Euler method, a coupling rigid-body dynamics model of a Trans-Medium Vehicle (TMV) separating from an Unmanned Underwater Vehicle (UUV) has been established. The modeling is based on the “holistic method” and “Kane” ideas respectively,

Redefining Optimal Coverage Path Planning for FLS‐Equipped AUVs With Deep Reinforcement Learning
ABSTRACT Autonomous Underwater Vehicles (AUVs) have emerged as indispensable tools for a variety of subsea tasks, from habitat monitoring and seabed mapping to infrastructure inspection and mine countermeasures. A fundamental challenge in this field is Coverage Path Planning (CPP), the problem of ensuring complete and efficient area coverage.

River Ice Analyses and Roughness Calculations Using Underwater Drones and Photogrammetric Approach
This study presents a methodology for determining hydraulic roughness (Manning's n) of fluvial ice using underwater drone and Structure from Motion (SfM) photogrammetry. The findings show that cost‐efficient equipment can be used to determine Manning's n for river ice, which supports modelling efforts, especially under intense warming in northern areas.

Effect of Wave and Ocean Current to Motion of Low-Velocity UUV
The wave and ocean current can evidently effect the motion of the low-velocity UUV, when the UUV moving close to the sea surface. To simulate the effect, we built the motion model of the UUV and the effect model of the wave and ocean current to the UUV ...
