Mechanical properties and damage evolution mechanism of rubber-gangue cemented backfill under different loading rates

Abstract This study investigates the rate-dependent mechanical behavior and damage evolution of rubber-modified cemented gangue backfill through multi-scale macroscopic and microscopic tests. A piecewise statistical damage constitutive model based on the Weibull distribution is e...

SFD-KD: Structured Feature Decoupling Knowledge Distillation for Fracture Detection

Accurate fracture detection in medical imaging is pivotal for intelligent orthopedic diagnostic systems, yet deploying high-capacity detection models on resource-constrained platforms remains a critical cyber-physical challenge. Conventional feature distillation based on Mean Squ...

Extreme Hydrological Events and Lake-Wetland Landscape Dynamics: Toward Adaptive Management in Large Freshwater Systems-Insights from Poyang Lake, China

Extreme hydrological events induced by climate change pose significant challenges to the ecological stability of river-connected lake-wetland systems. Poyang Lake, China’s largest freshwater lake, provides an ideal case for investigating landscape responses to compound drought an...

Opposing effects of shared and unshared networks drive species coexistence in intransitive competitive ecosystems

Understanding the mechanisms of species coexistence in intransitive competitive communities, which is generally considered favorable for promoting biodiversity maintenance, has long been a crucial issue in ecology. The role of species dispersal along different pathways in shaping...

Differential Game Analysis of Cross-Border E-Commerce Supply Chains Under Dual Trade Barriers

This study examines a two-echelon cross-border e-commerce (CBEC) supply chain under the joint constraints of technical barriers to trade (TBTs) and tariffs. To capture the cumulative nature of foreign-market access, the degree of trade barrier breakthrough is modeled as a continu...

An efficient cross-chain interaction mechanism for large-scale multichain environments

Abstract To address the scheduling difficulties, high verification overhead, and insufficient transaction processing efficiency encountered in cross-chain interactions under high-concurrency scenarios, an efficient cross-chain interaction mechanism is proposed. First, a cross-cha...

Experimental and Numerical Study on the Flexural Performance of Prefabricated RC Beams with UHPC–Cogging–Grouted Sleeve Composite Joints

This study investigates the flexural performance of prefabricated reinforced concrete (RC) beams with a novel UHPC–cogging–grouted sleeve composite joint. Five beam specimens—one cast-in-place reference and four prefabricated examples—were tested under four-point bending. The key...

EcoRestore-KG: A Multi-Agent Framework for Knowledge Graph Construction in Territorial Ecological Restoration

Territorial ecological restoration involves a continuous chain of tasks, including degradation diagnosis, target identification, zoning-based governance, process monitoring, effectiveness assessment and adaptive management. The relevant knowledge is widely distributed across poli...

Energy Evolution and Acoustic Emission Characteristics of Tailings Backfill with Different Fly Ash Content

Abstract In this paper, with the help of acoustic emission (AE) monitoring technology, the mechanical properties of tailings backfill under uniaxial compression with three kinds of fly ash (FA) content, slurry concentration of 70%, and ash-to-sand ratios of <mml:math xmlns:mml="h...

Self-assembled iridium(III) photosensitizers induce cuproptosis without copper supplementation for efficient anticancer therapy

Photodynamic therapy (PDT) is a promising treatment that uses reactive oxygen species (ROS) generated by light-irradiated photosensitizers (PSs) in the presence of molecular oxygen (O₂). However, its efficiency is heavily compromised in aqueous environments and living systems. He...

Effect of Maternal Genotype on Chromosomal Introgression in Lilium (Liliaceae) Hybrids from Parents Producing Aneuploid Female and Male Gametes (AAA × LAAA and LAA × LAAA)

Interspecific hybridization is a key strategy for germplasm innovation in lilies (Lilium spp., Liliaceae). However, successful hybridization between aneuploid female and aneuploid male gametes has not been reported in this genus. We used two triploid female parents—autotriploid (...

Fabrication of Dense Crosslinked Network in Polybenzoxazine Aerogels via Melamine for High Compressive Strength

ABSTRACT Polybenzoxazine (PBz) aerogels fabricated via a water–ethanol mixed green system are attractive for thermal insulation but are limited by inherent brittleness and the environmental burden of their conventional fabrication. To address this, we developed a high‐strength hy...
