Dynamic Voltage-Response Estimation for Blade-Tip Timing Sensors Based on EHHO-BP Network and Waveform Mapping

Blade-tip timing (BTT) sensor technology is widely used for non-contact blade vibration measurement. However, conventional BTT methods mainly rely on sparse time-of-arrival (TOA) information, which limits continuous sensor-domain characterization of blade vibration. To address th...

Effects of powder forming method and heat treatment process on microstructure and mechanical properties of ATI 718Plus alloy by laser additive manufacturing

ATI 718Plus alloy powders were prepared by vacuum induction melting gas atomization (VIGA) and plasma rotating electrode preparation (PREP) methods. Effects of direct aging (DA) and homogenization-solution-aging (HSA) heat treatment processes on microstructure and mechanical prop...

Normal-stress unclamping promotes cascading instability in deep mining-induced seismicity

Deep mining-induced seismicity poses a severe dynamic hazard and offers a near-field setting for examining fault interaction under rapidly evolving excavation-induced stress fields. Conventional stress-concentration frameworks may overlook failure paths governed by normal-confine...

Semantic-guided 3D Gaussian splatting for sparse-view reconstruction in industrial digital twins

Novel view synthesis, which is essential for three-dimensional (3D) reconstruction, traditionally requires dense image sets and pre-calibrated camera parameters. However, in industrial digital twin applications spatial constraints often limit data acquisition to sparse views that...

CGCLER: Causality-Enhanced Graph Contrastive Learning for Explainable Recommendation

Explainable recommendation has been conceptualized as a joint ranking task encompassing both items and explanations within contemporary recommender system research. The modeling of user–item–explanation triplets can be effectively facilitated by Graph Neural Networks (GNNs) due t...

A coupled age–viscosity–flow finite-element framework for ageing-gel injection and sealing in underground void networks

Age-dependent viscosity strongly influences gel migration and sealing in underground void networks. However, conventional models commonly update viscosity using global elapsed time and cannot represent spatially non-uniform transport histories. This study develops a finite-elemen...

Predictor-Dependent Amplification of Branch Mispredictions in Out-of-Order Superscalar Processors: A RISC-V gem5 O3 Study

Branch prediction errors can reduce superscalar throughput by more than the error frequency alone suggests because a single misprediction can trigger redirect, squash, refetch, refill, and window recovery, which collectively disrupt sustained instruction-level parallelism. This p...

Robust and Efficient Dual-Strategy Switch Migration for Failure Recovery in Software-Defined Satellite Networks

Software-defined satellite networks (SDSNs) enhance resource utilization and flexibility in space-based networks by leveraging a global view and programmability. A highly reliable control plane is essential to sustain network operations. However, the highly dynamic topology and p...

Reliability-Aware Multi-Modal Sentiment Analysis Under Missing and Corrupted Modalities

Multi-modal sentiment analysis integrates linguistic, acoustic, and visual evidence, yet the reliability of these streams varies across samples because of missing observations, masking, measurement noise, and feature corruption. This paper presents a trainable reliability-aware e...

Observer-Based Finite-Time Adaptive Fuzzy Control for Nonlinear Systems with Full-State Constraints

This paper investigates practical finite-time adaptive fuzzy control for uncertain nonlinear systems subject to full-state constraints and unmeasured state variables. To deal with the inaccessibility of some state variables, an observer is constructed. A state-dependent nonlinear...

Online-Channel Introduction and Residual-Capacity-Based Differentiated Pricing in Spent Power-Battery Recycling

This study investigates the effects of introducing a manufacturer-operated online recycling channel (hereafter “online channel”) and adopting a residual-capacity-based differentiated-pricing strategy in spent power-battery recycling. We develop a manufacturer-led Stackelberg game...

Hierarchical Enzyme Function Prediction Based on Structural Confidence and Active-Site-Aware Attention

Accurate enzyme function prediction is important for protein functional annotation, drug discovery, metabolic-pathway analysis, and synthetic biology. Although recent structure-based methods have improved Enzyme Commission (EC) number prediction, they still have several limitatio...

Impacts of Cold Waves and Urban Heat Islands on Heating Energy Consumption Differences Across Intra-Local Climate Zones

Most studies have explored the impact of different types of local climate zones (LCZs) on energy consumption, but few have examined climate differences within intra-local climate zones (intra-LCZs) and the impact of cold waves (CW) on energy consumption. This study conducted a 15...

Synergistic enhancement of strength and ductility in wire arc additive manufactured Mg-Gd-Y-Zr alloy via Ag addition

To overcome the strength-ductility trade-off and poor formability of high-RE magnesium alloys, Mg-13Gd-3Y-XAg-Zr (x = 0, 1, and 2 wt.%) thin walls were fabricated via wire arc additive manufacturing (WAAM), followed by subsequent solution treatment and peak-aging treatment (T6)....

Morphological Buffering in Neuro-Architecture: Interactive Effects of Color, Shape, and Area Proportion on Affective Processing

While architectural visual features significantly influence human emotion, the spatiotemporal neuro-mechanisms underlying their interactive effects remain poorly under-researched. This study systematically decoupled the dynamics of indoor spatial perception by investigating the i...

Open-Set Semiconductor Defect Classification in SEM Images via Uncertainty-Aware Local Prototype Alignment

Automated classification of scanning electron microscope (SEM) defects is complicated by acquisition-domain shift, long-tailed classes, and target-only defect types that invalidate the closed-set assumption. We propose an offline open-set adaptation framework that combines a thre...

Motion-State-Aware Adaptive Step-Length Smartphone PDR for GPS-Denied Pedestrian Localization

Smartphone-based pedestrian dead reckoning (PDR) provides an infrastructure-free solution for two-dimensional (2D) planar localization in GPS-denied environments, but its open-loop nature makes it sensitive to accumulated step-length and heading errors. These errors grow when ped...
