Neural networks and dynamical system techniques for volcanic tremor analysis

Annals of Geophysics, 1996
A volcano can be seen as a dynamical system, the number of state variables being its dimension N. The state is usually confined on a manifold with a lower dimension f, manifold which is characteristic of a persistent «structural configuration».

Plaque‐Targeted Delivery of Fluoride‐Free MXene Nanozyme for Alleviating Atherosclerosis via Sonocatalytic Therapy

Advanced Materials, EarlyView.
This work has developed a dual enzyme‐mimicking and ultrasound‐responsive Nb2C‐Pt@HA‐PEG nanozyme. ROS‐eliminating and anti­inflammatory capability of Nb2C‐Pt@HA‐PEG under US irradiation are demonstrated on macrophages and endothelial cells in vitro. Nb2C‐Pt@HA‐PEG‐mediated sonocatalytic therapy exerts an outstanding anti‐atherosclerosis efficacy by ...

3D Habitat Complexity and Coral Morphology Modulate Reef Fish Functional Structure in a Marine National Park

Ecology and Evolution
The ongoing degradation of coral reef habitats is widely acknowledged to have adverse effects on the abundance and diversity of reef fish populations, yet the direct effects on ecosystem functions remain uncertain. This study used a quantitative approach

Ash plume properties retrieved from infrared images: a forward and inverse modeling approach

, 2014
We present a coupled fluid-dynamic and electromagnetic model for volcanic ash plumes. In a forward approach, the model is able to simulate the plume dynamics from prescribed input flow conditions and generate the corresponding synthetic thermal infrared (
