ENSO-Flavor Differences in Indonesian Marine Heatwaves: Satellite SST, Physical Covariates, and Coral Habitat Suitability

Marine heatwaves (MHWs) in the Indonesian Seas develop within a long-term rise in sea surface temperature and strong interannual climate variability. We analyze daily NOAA Optimum Interpolation Sea Surface Temperature version 2.1 for 1982–2022 and compare five Eastern-Pacific (EP...

TEMPOL improves the post-thaw sperm quality in Zhikong scallops Chlamys farreri

Previous study demonstrated that the post-thaw sperm performance was significantly affected by the disturbance of antioxidant defense system due to the overproduction of reactive oxygen species (ROS). The present study examined whether such a disturbance could be mitigated by the...

Accelerated Zeolite Defect Healing Suppresses Oxygen-Containing Species Trapping for Tandem Propene Epoxidation

Abstract Selective oxidation of chemical feedstocks with in situ-generated H2O2 offers a sustainable route to high-value oxygenates, yet such tandem catalysis is often fundamentally limited by the trapping of oxygen-containing species, including H2O2-derived intermediates and oxy...

The Effect of Drainage Conditions on the Static Shear Characteristics of Calcareous Silt

Facing the global challenge of sea-level rise, the stability of land reclamation engineering is severely threatened by the weak calcareous silt interlayers formed during its construction process. This study investigated the mechanical behavior and particle breakage characteristic...

Contribution of the Pacific Decadal Oscillation to Global Mean Sea Level Trends: Revisited

Abstract Three decades of satellite altimeter observations reveal a continued rise in global mean sea level (GMSL), with the rate of rise reflecting the combined effects of decadal variability and long‐term warming. By decomposing 30‐year running trends of reconstructed sea level...

Fast Trajectory Similarity Computation over Road networks

With the widespread application of trajectory data in areas such as traffic management and route planning, efficiently computing trajectory similarity for fast retrieval has become a critical challenge. Existing methods for trajectory similarity measurement often face issues of l...

A source-to-sea decision-support framework for wet-weather wastewater load management: evidence from Jiaozhou Bay

Coastal concentration compliance can overlook increased wastewater throughput during wet weather. We developed a source-to-sea decision-support framework using 2019–2022 wastewater, river, and marine observations from Jiaozhou Bay, China. The analysis combined source-record audit...

High-resolution late Quaternary Indo-Pacific Warm Pool benthic δ18O stratigraphy for evaluating the precession timing of the marine Asian monsoons

The timing of Quaternary precession-scale (23 kyr) monsoon variations across the Asia-Australia and the Indo-Pacific regions remains highly debated. The Asian monsoon phase differences of approximately 5 ka reported between a suite of marine sedimentary and speleothem proxy recor...

Is the multilingual motivational self system a unified construct or an aggregation of language-specific selves?

With the acceleration of globalisation and the increasing prevalence of multilingual education, the traditional L2 Motivational Self System (L2MSS) has shown limitations in explaining the complex motivational configurations of multilingual learners. This study aims to examine the...

Study on Corrosion and Mechanical Property Degradation Behavior of NiCrMoV Steel Under Laboratory‐Simulated Low‐Temperature Seawater Conditions

To elucidate the corrosion behavior and mechanical property degradation mechanisms of NiCrMoV steel under laboratory‐simulated low‐temperature seawater conditions, this study conducts systematic experiments under three static temperature conditions and two freezing‐thawing con...

Molecular π‐Conjugation Engineering Enables Flexible and Water‐Resistant Organic RTP Materials for Wearable Applications

ABSTRACT Organic room‐temperature phosphorescence (RTP) materials for flexible and aquatic applications are limited by triplet exciton instability under deformation and environmental perturbation. Here, molecular π‐conjugation engineering is integrated with polymer‐matrix confine...

FBMN-Guided Discovery of Cyanogrisides from Mutant Strain CRM005 and Structural Diversification

Abstract Through genome mining and metabolomic analysis of the mutant strain CRM005, combined with feature-based molecular networking (FBMN) deduplication, five novel natural cyanogrisides (1–5) were selectively isolated and characterized, alongside six previously reported analog...

Fluid–substrate coupled controls on mineral‑phase selection in the Kunlun hydrothermal system

Abstract Mineral precipitation at submarine hydrothermal vents transfers redox‑sensitive elements from the lithosphere to the ocean. However, conventional plume and sediment‑trap sampling poorly preserves particle‑scale signatures generated at reactive interfaces, hindering robus...

Design, Synthesis, and Anti-Inflammatory Activity Evaluation of Novel thieno[2,3- d ]Pyrimidin-4(3 H )-One-Based NLRP3 Inflammasome Inhibitors

Abstract The NLRP3 inflammasome plays a critical role in the pathogenesis of inflammatory diseases and has emerged as a promising therapeutic target. Our preliminary studies revealed that istradefylline, an anti-Parkinsonian agent, exhibits moderate NLRP3 inhibitory activity. Fur...

In situ evidence of tiered adaptations buffering a chemosynthetic clam holobiont against environmental sulfide fluctuations

Deep-sea holobionts adapt to extreme environmental fluctuations, but the molecular mechanisms underlying resilience remain poorly understood. We investigated the vesicomyid clam Archivesica marissinica and its sulfur-oxidizing symbionts during sulfide shortage via in situ transpl...

Non-Target Arthropod Community Variation Associated with Abamectin Trunk-Injection History in a Pinus massoniana Plantation

Abamectin trunk injection is used to control pine wilt disease, but field evidence linking injection history to non-target arthropod communities is limited. We compared uninjected plots with plots injected once in March 2024 (ATI1) or March 2022 (ATI3) in a Pinus massoniana plant...

FoxL2 exhibits two-stage expression and maintains the ovarian niche in a lophotrochozoan

The genetic pathways governing sex determination remain a key enigma in lophotrochozoans, a major branch of bilaterian animals, hindering a comprehensive understanding of their evolution. Here, we enable genetic analysis in the gonochoristic scallop Chlamys farreri by developing...

Dual-Optimized Medium-Entropy Alloy Heterojunction: Synergistically Enhancing Surface Kinetics and Interfacial Mass Transfer for Hydrazine-Assisted Hydrogen Evolution

Abstract To address the prominent “bubble shielding” effect at high current densities during hydrazine oxidation reaction (HzOR) as a replacement for the traditional oxygen evolution reaction (OER), this study successfully designed a medium-entropy heterojunction electrocatalyst...

Closed-Form and Boundary Expressions for Task-Success Probability in Status-Driven Systems

Status-driven task offloading appears in many systems such as vehicular coordination, UAV control, and compute-first networking, where an user-side node (or access point, AP) forwards user tasks based on periodically received server status. Whether a task ultimately succeeds depe...
