Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

Hybrid phase shift and shifted sideband beamforming for large‐aperture MIMO sonar imaging
A multiple‐input multiple‐output (MIMO) sonar can form a large‐aperture virtual uniform linear array (ULA) from a small number of physical elements. However, the large‐aperture MIMO sonar encounters a dilemma between the computation load and the imaging ...

An integrated microwave‐assisted extraction (MAE) and spray‐drying process was developed and optimized by response surface methodology (RSM) to produce a stable chlorophyll powder from the underutilized aquatic macrophyte Ceratophyllum submersum L. The resulting powder combined high pigment retention (67.81% chlorophyll; 63.74% recovery) with favorable

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.

Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...
