Palladium-Catalyzed Narasaka–Heck Carbonylation Using Cr(CO)6 as Carbonyl Source: Access to Ester-Containing Pyrrolines

Abstract An unprecedented Pd-catalyzed CO gas-free Narasaka–Heck carbonylation using Cr(CO)6 as a convenient carbonyl source has been developed for the step-economic construction of ester-containing pyrrolines. Notably, this method overcomes the limitations of conventional radica...

Examining the Role of AI-Assisted Learning in Fostering Students’ Entrepreneurial Intention Within an Interdisciplinary Course Context: An Extended UTAUT-Based PLS-SEM Study

The integration of AI into higher education provides new opportunities for supporting learning in interdisciplinary contexts and fostering entrepreneurial development. However, previous research has mainly focused on AI technology adoption, with limited attention paid to its broa...

Mitochondrial Remodeling, Cytoskeletal Dynamics, and Translational Control During Drosophila Spermatid Elongation: An Integrative Review

Spermatogenesis in Drosophila melanogaster is a classical model for studying cell polarity establishment, organelle remodeling, and extreme cellular morphogenesis. Spermatid elongation involves a series of highly coordinated dynamic events, including nuclear polarization, axonema...

Understanding projected uncertainty of Southern Ocean sea salt aerosol in CESM1-LE: role of internal variability

Abstract Southern Ocean (SO) sea salt aerosol is key to Earth’s energy budget, but its future changes are highly uncertain. Here using a 40-member ensemble from the Community Earth System Model Large Ensemble (CESM1-LE) project, we find that projected SO sea salt is modulated by...

Strong tropical cyclones have a more gradual increase trend through interaction with ocean subsurface

Understanding changes in global tropical cyclone (TC) intensity and their long-term trends is critical for enhancing societal resilience. Given their disproportionate impacts, shifts in strong TCs, which are defined here as Category 4 and above, are of particular concern. We exam...

Seasonal variations and controlling factors of nitrogen fluxes at the sediment-water interface in a semi-enclosed inland sea

Abstract. Nitrogen fluxes across the sediment-water interface and nitrogen removal from sediments are essential components of nitrogen cycle in semi-enclosed inland seas. However, the difficulty in observational sampling hinders continuous data availability that is necessary to u...

Aggregicoccus is a myxobacterial genus inherently deficient in fruiting genes

ABSTRACT Myxobacteria are fascinating and important prokaryotes with remarkable multicellular behaviors, which make them a model system for studying prokaryotic development and cooperation. Although there have been sporadic discoveries of myxobacterial species unable to fruit, it...

The double-edged sword of proactive GenAI: how it shapes user usage intention

Purpose With the emergence of generative AI (GenAI), proactive services that initiate actions on behalf of users without explicit prompts are becoming increasingly prevalent. Although such services can enhance human-AI interaction, emerging evidence suggests that GenAI proactivit...

Fe‑Doped Triphenyl-Substituted Triazine Graphdiyne Semiconductor with Room‑Temperature Ferromagnetism

Abstract The modulation of ferromagnetic order in 2D carbon materials has attracted increasing attention for the development of next-generation spintronic devices and multifunctional information storage technologies. In particular, the graphdiyne (GDY) family has been regarded as...

A Few-Shot Load Identification Method with Class-Incremental Learning

Non-intrusive load monitoring (NILM) enables fine-grained energy awareness and demand-side energy management in residential and commercial buildings, but practical deployment requires load identification models to accommodate newly introduced appliances from only a few labeled sa...

Unsupervised dual-branch attention network for multifrequency ground-penetrating radar data fusion: an application to Arctic sea ice exploration

Abstract Ground-penetrating radar (GPR) is a nondestructive electromagnetic (EM) method used for subsurface target detection and stratigraphic imaging. The use of a single-frequency GPR profile is inherently limited by the trade-off between penetration depth and vertical resoluti...

Optimal Dietary Glycerol Monolaurate Supplementation Enhances Growth Performance and Intestinal Health in Hybrid Grouper (♀ Epinephelus fuscoguttatus × ♂ E. lanceolatus)

This study investigated the effects of glycerol monolaurate (GML) on the growth performance, physiological efficacy, intestinal structure, and microbiota of hybrid juvenile ♀ Epinephelus fuscoguttatus × ♂ E. lanceolatus. A total of 594 groupers were administered diets supplemente...

A 3D VTI Factored Eikonal Solver Using a Six‐Tetrahedron Pyramidal Stencil

ABSTRACT Accurate traveltime computation for the eikonal equation is essential in seismic applications such as tomography and migration. The fast sweeping method is widely used because of its unconditional stability and computational efficiency. We develop a three‐dimensional fas...

Mesozoic Microplates of East Asia: A New Reconstruction

Abstract The complex tectonic evolution and regional remagnetization in East Asia since the Mesozoic have led to debates over plate reconstructions. By synthesizing high‐quality paleomagnetic poles and geological data, this study develops a new plate reconstruction model for East...

Emerging nitrogen-driven urban atmosphere control on aerosol iron dissolution for biogeochemical cycles

Iron (Fe) is a critical micronutrient regulating marine productivity and the global carbon cycle, yet its atmospheric dissolution mechanisms remain debated for biogeochemical cycle. The prevailing “iron-sulfur coupling” paradigm has traditionally explained proton-promoted dissolu...

A Lyapunov‐Like Function‐Based Event‐Triggered Stabilization Scheme for Nonlinear Discrete‐Time Systems

ABSTRACT This study investigates stabilization methodologies utilizing event‐triggered mechanisms tailored for specific discrete‐time nonlinear systems. A Lyapunov‐like stability theorem is first established, which relaxes the conventional strict monotonic decrease constraint on...

Microbial Ethane and Propane Production and Ethanogenic Enrichment of Methanogens in Coastal Sediments

Abstract Ethane and propane are short‐chain alkanes that are ubiquitous in marine environments, while the biological formation of ethane and propane remains largely unconstrained in coastal subsurface sediments. Here, we detected nanomolar concentrations of ethane and propane alo...

Screening Plus Training: A Strategy to Counter Germplasm Degeneration in Cultivated Kelp ( Saccharina japonica )

ABSTRACT Based on the introduced founder sporophytes, a set of S. japonica varieties and a few hybrid kelp have been bred and intensively cultivated in China. The cultivation of S. japonica has been running up against the impasse of germplasm degeneration characterized by low gro...

Storm-driven upwelling contributes to Beaufort Gyre intensification through rapid geostrophic adjustment and eddy-related freshwater redistribution

Abstract The Alaskan North Slope (ANS) is a region of recurrent wind-driven upwelling, but the extent to which these events influence Beaufort Gyre (BG) variability and Arctic freshwater redistribution remains uncertain. We combine ERA5 winds, mooring velocity and hydrography, sa...
