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».

Ultrasound‐Triggered Nanobubbles for Endothelial‐Targeted Drug Delivery in the Detection and Treatment of Doxorubicin‐Induced Cardiotoxicity

Advanced Healthcare Materials, EarlyView.
The DA/VTP‐NBs selectively recognized cardiac ECs damaged by DIC and achieved cell‐level targeted imaging. Then US‐triggered controlled release successfully enabled the release of DAPA within the DA/VTP‐NBs at the site of injury. This precise on‐demand drug release approach amplifies a series of localized therapeutic effects through the mtDNA‐mediated ...

Could seismo-volcanic catalogs be improved or created using weakly supervised approaches with pre-trained systems? [PDF]

Natural Hazards and Earth System Sciences
Real-time monitoring of volcano-seismic signals is complex. Typically, automatic systems are built by learning from large seismic catalogs, where each instance has a label indicating its source mechanism.

Opinion: Gavage Administration of MXene as a Route‐Specific Alternative to Intravenous Injection into the Bloodstream of Laboratory Animals for Reducing Systemic Nanotoxicity Risks in Immunosuppression and Post‐Transplantation Models with Bile Acid Modification

Advanced Healthcare Materials, EarlyView.
Recent studies reported immunosuppressive properties of specific MXene nanomaterials. Their intravenous injection into the bloodstream of laboratory animals has been a common delivery method to suppress systemic inflammation and prevent transplant rejection.

Satellite images monitor volcanos

Eos, Transactions American Geophysical Union, 1989
In response to the rare but serious threat that volcanoes pose to airplanes, the Federal Aviation Administration and the National Oceanic and Atmospheric Administration recently established a volcano monitoring service. Under the agreement NOAA will contact FAA if satellite images show ash eruptions reaching higher than 5 km along flight routes.The ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

Advanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...
