Determination of the parameters in the Freundlich function using a modified method in the case of the bioaccumulation factor of Populus tremula

This study proposes a modified coefficient-estimation approach for the Freundlich function to model soil-to-leaf element transfer without relying on conventional logarithmic linearization. For this purpose, the leaf uptake capability of European aspen (Populus tremula L.), which...

Late Glacial temperature, anoxia, and primary production in Lago di Mezzano, Central Italy

In the North Atlantic domain, the Late Glacial period (19–11.8 cal ka BP) is characterized by rapid, high-amplitude climatic changes. The amplitude of temperature change in the Central Mediterranean region remains debated because reconstructions are limited and often contradictor...

Adaptive Inversion Optimization of the Static Factor of Safety for Newmark-Based Earthquake-Induced Landslide Susceptibility Assessment

Rapid regional evaluation of earthquake-induced landslide susceptibility via the traditional Newmark model is often constrained by geotechnical parameter spatial variability and subjective empirical adjustments in static factor of safety (Fs) calculations. To resolve this bottlen...

The effect of hybrid models integration sequence: taking Fushun area as an example

Landslide susceptibility zoning (LSZ) is a crucial step in reducing landslide related losses, and its accuracy remains a long-standing research focus. Hybrid models are widely used, but little is known about coupling sequences. Here, we show that the accuracy of hybrid models can...

Hydrocarbon Generation Kinetics and History of the Middle Jurassic Yangye Formation in the Southwestern Tarim Basin Piedmont, Northwest China

Abstract Shale gas discovered in the Middle Jurassic Yangye Formation (Well TNY1) confirms the hydrocarbon generation potential of the Southwestern Tarim Basin Piedmont (SWTBP), yet its hydrocarbon generation patterns, processes, and potential require clarification. This study co...

Analytical model for the progressive collapse resistance of a novel fully assembled concrete beam‐column substructure with bolted flange connections

Abstract This study develops an analytical model to characterize the progressive collapse resistance of a novel fully assembled concrete beam‐column substructure with bolted flange connections. The model, which idealizes the bolts as an equivalent continuous section to determine...

Multi-Year Variation Characteristics and Driving Forces of Groundwater Levels in the Yibin Area, Southern Sichuan, China

To support groundwater protection and sustainable utilization in southern Sichuan, this study aims to clarify the multi-year variation characteristics of groundwater levels (GWLs) and identify their main driving factors in the Yibin region. In this paper, 2019–2024 GWL monitoring...

Early Jurassic Granitoids in the Pairigang Area, Tibet: Implications for the Evolution of the Neo-Tethyan Ocean and the Accretion of Juvenile Crust in the Southeastern Lhasa Block

The Jurassic represents one of the most significant periods within the widespread Mesozoic magmatism of the Lhasa Block; however, its formation age and petrogenesis have led to controversy over the deep genetic mechanisms responsible for magmatism. To address this, we present new...
