Article Abstract
Illegal, unreported, and unregulated (IUU) fishing threatens the sustainability of fisheries and communities dependent on them. The Port State Measures Agreement (PSMA) is a key tool for combatting IUU fishing by foreign fleets, requiring standardized inspections, information sharing, and port denial. Using satellite data, we characterized how PSMA has affected high seas vessel behavior and identify opportunities to strengthen its impact. PSMA adoption has increased travel distances to the nearest ports in States not Party to PSMA and channeled more fishing effort to domestic and PSMA Party ports. However, domestic fishing fleets need greater attention because they constituted 66% of port visits in 2021. Among reflagged vessels, we also found a 30% increase in visits to PSMA ports by vessels shifting to domestic flags after PSMA entered into force, allowing them to avoid PSMA requirements for foreign vessels. Our results highlight the centrality of implementing consistent, effective port State measures across foreign and domestic fleets to address IUU fishing risks.

Event-triggered dynamic landing control of cooperative USV-UAV plant with the compensation mechanism for rolling kinematics.

In this paper, an event-triggered fuzzy control algorithm is proposed for the unmanned surface vessel (USV) and unmanned aerial vehicle (UAV) cooperative plant to achieve the high-precision landing mission. In the guidance module, an L virtual ship-L virtual aerial vehicle (LVS-LVA) guidance principle is developed to generate the reasonable reference signals for the USV-UAV plant under the landing mission. The proposed guidance principle incorporates a rolling kinematic compensation mechanism based on the 4-degree-of-freedom model of USV, specifically designed to counteract wave-induced rolling disturbances during UAV landing operations on unstable marine platforms.

Microplastics (MPs) are raising significant global concerns due to their environmental impacts. While most studies have focused on the effects of individual MP types, MPs in natural environments typically coexist as multiple types, and their combined effects remain poorly understood. In this study, we conducted a microcosm experiment with four levels of MP diversity (0, 1, 3, and 5 types) to investigate the effects of MP diversity on soil ecosystem functions using metagenomic sequencing.

The ataxia telangiectasia mutated (ATM) kinase orchestrates the early stages of DNA double-strand break repair by promoting hyperphosphorylation of CtIP, a key step in the initiation of DNA end resection. However, the regulatory mechanisms controlling resection extent remain incompletely understood. Here we identify ERCC6L2 as a key regulator of DNA end resection in response to ATM inhibition.

The urgent need to reduce fossil fuel emissions demands advanced control technologies beyond conventional catalysts. This review uniquely offers a comprehensive analysis of composite catalysts tailored to capture the full spectrum of fossil fuel pollutants, unlike prior studies that address individual emissions separately. It covers fundamental principles, reaction mechanisms, and recent material innovations, emphasizing multi-metallic, nanostructured, and hybrid catalyst designs.
