Two-Stage Probabilistic Robust Control for Aircraft Longitudinal Short-Period Dynamics Using Pareto Optimization

This paper proposes a two-stage probabilistic robust controller design framework based on Pareto optimization (TSPO) for aircraft longitudinal short-period motion subject to aerodynamic parameter uncertainties. Unlike conventional robust control approaches such as LQR, H∞, and LM...

Asymmetric interactions in the Hawk–Dove game enhance evolutionary complexity and resource utilization efficiency

The Hawk–Dove game is one of the most important theoretical models in evolutionary game theory. To reveal the coupling effects of symmetric and asymmetric interactions on the Hawk–Dove game, we investigate the evolutionary dynamics of a newly constructed Hawk–Dove game composed o...

A fractional integral ghost-structure method for a space-fractional anisotropic monodomain model in realistic bi-ventricular cardiac electrophysiology

This paper proposes a space-fractional anisotropic monodomain model for simulating action potential propagation in deforming cardiac tissue. The model incorporates an anisotropic conductivity tensor that depends on the local fiber orientation and evolves with tissue motion, there...

Mechanisms of non-monotonic signal dependence on repetition rate in high-repetition-rate nanosecond LIBS

High-repetition-rate nanosecond laser-induced breakdown spectroscopy (LIBS) offers advantages such as small ablation crater and high signal-to-noise ratio. To investigate the non-monotonic influence of repetition rate on signal intensity, we conducted high-repetition-rate LIBS ex...

Hierarchical Sparse-Routing-Enabled Mamba Scanning for Tire Pattern Recognition

To tackle the challenging representation problem of fine-grained tire tread patterns, we present a hierarchical sparse-routing-enabled multi-mode multi-directional Mamba (HSR-Mamba) scanning framework for tire pattern recognition to improve performance, and it mainly consists of...

A data-driven and mechanism-explicit combined electrical performance predicting model for photovoltaic modules under engineering conditions

In practical engineering, photovoltaic (PV) module electrical performance, influenced by multiple and dynamic environmental factors, depends on understanding their complex nonlinear relationship for optimal maximum power point tracking (MPPT) target determination. However, existi...

SM2-PRE+: A Lightweight Pairing-Free Proxy Re-Encryption Scheme for Secure IoMT Healthcare Data Sharing

With the rapid development of the Internet of Medical Things (IoMT), wearable sensors and intelligent medical terminals continue to generate a large amount of sensitive medical data, which needs to be uploaded to the cloud platform for storage and sharing. However, IoMT devices u...

2D Halide Perovskite Single Crystals Constructed by Aromatic Diammonium for High Sensitivity and Low Detection Limit X‐Ray Detectors

ABSTRACT 2D perovskites exhibit remarkable features such as strong X‐ray absorption, high resistivity, and low ion migration, endowing them with high competitiveness in X‐ray detection. Although numerous 2D perovskites (RP, DJ, and ACI phases) have drawn substantial attention, th...

Information-Entropy-Guided Counterfactual Stability Modeling and Replay-Based Selective Override for Context-Fragile Branch Prediction

Modern out-of-order processors depend critically on TAGE family branch predictors, which often struggle with context-fragile branches whose outcomes are highly sensitive to slight perturbations in the most recent global history. Existing predictors are confined to single-path fac...

GSFDoubleU ‐Net: A Dual‐Branch Architecture Incorporating Gated Self‐Attention Fusion for Enhanced Gastric Polyp Image Segmentation

ABSTRACT Gastric polyps are clinically important lesions whose accurate delineation in endoscopic images can support lesion assessment and treatment planning. However, small size, weak contrast, irregular morphology, indistinct boundaries, and interference from surrounding gastri...

Dynamic Modeling and Self-Tuning Fuzzy Skyhook Control of a Metro Vehicle with a Flexible Carbody and Semi-Active Suspension

Lightweight metro carbodies may exhibit elastic modes within ride-comfort-relevant frequency bands, limiting semi-active suspension controllers tuned offline for nominal conditions. This study proposes a skyhook-based parameter self-tuning fuzzy control (PSTFC) strategy for later...

Persona-centric Metamorphic Relation Guided Robustness Evaluation for Multi-turn Dialogue Modeling

Abstract Retrieval-based dialogue systems aim to select a proper response according to multi-turn conversational history. Persona-based conversation utilizes prior knowledge to maintain persona consistency, enhancing retrieval accuracy. However, reference-based evaluation relies...
