Dataset-Driven Exploratory Deep Reinforcement Learning Using SINDy-Based Data Augmentation from Limited Indoor Thermal Measurements

This study examines the feasibility of combining Sparse Identification of Nonlinear Dynamical Systems (SINDy)-based data augmentation with an Actor–Critic deep reinforcement learning (DRL) model in a dataset-driven exploratory policy-learning configuration under limited-data cond...

Spatiotemporal Changes and Driving Factors of Ecosystem Services in the Yangtze River Delta, China: Insights from XGBoost and Structural Equation Modeling

Ecosystem services (ESs) are the benefits that humans derive from ecosystems. Clarifying their spatiotemporal changes and driving factors is fundamental to regional ecological security. The Yangtze River Delta (YRD) is one of the most urbanized and human-disturbed regions in Chin...

Multi‐Scenario Adaptive High‐Fidelity Self‐Healing Elastomer Based on Poly(Ionic Liquid) Containing Polyurethane for Temperature‐Pressure Sensing and Human‐Machine Interaction

ABSTRACT Skin‐friendly ionogels with multi‐scenario adaptive, high‐fidelity, and self‐healing performances were critical building units in wearable signal transmission devices. Traditional ionogels doped with small‐molecule ionic liquids (SMILAs) into polymers yielding weak inter...

Phase-locking in nonidentical coupled light-fueled liquid crystal elastomer self-oscillators

Self-oscillation refers to feedback-driven and sustained periodic motion without external periodic forcing. In practice, self-oscillators often exist as collectives of nonidentical units, whose intrinsic differences give rise to intricate dynamics of competition and compromise. A...

Steering Reaction Coordinates on Laser-Programmed Fe/FeO/Ag Electrodes for Nitrate-to-Ammonia Electrosynthesis

Abstract Electrocatalytic nitrate reduction to ammonia (NO3RR) offers a dual-benefit strategy for pollution remediation and sustainable NH3 synthesis, but steering the complex eight-electron/proton reaction coordinate on earth-abundant iron catalysts remains challenging due to sl...

BayesSeg: A Bayesian Optimization Framework for State Segmentation of Electricity Consumption Time Series

In Non-Intrusive Load Monitoring (NILM), adaptive segmentation of electricity consumption time series is critical for appliance recognition. However, prevailing methods face challenges including heuristic parameter tuning, boundary sensitivity, and metric saturation. This paper p...

Mechanisms of operational parameters influencing aeration performance in inverted umbrella aerators: an experimental study supported by CFD analysis

ABSTRACT The graphical abstract presents a comprehensive overview of the inverted umbrella aerator study. The top left illustrates a schematic of the aerator in a 5m multiplication sign 4m multiplication sign 1.2m tank, with its variable immersion depth spanning -60 to +80mm. Adj...

Rethinking the determinants of urban economic resilience: the role of intercity investment network in Chinese cities

Faced with rising urban uncertainties, understanding the drivers of urban economic resilience (UER) has become a critical issue. Rather than focusing solely on internal urban attributes, this study adopts an external perspective and investigates how intercity investment networks...

Influence of Relative Spatial Layout of Fire and Openings on Neutral Plane Characteristics and Distribution Mechanisms of Mass and Heat Release for Spill Plumes in Compartment Fires

This paper presents a numerical investigation into full-scale double-opening compartment fires. It aims to reveal the underlying mechanisms by which the relative spatial layout of the fire source and openings influences neutral plane characteristics, flow field dynamics, and the...

From Digital Documentation to Rule-Based Regeneration: A Shape Grammar Approach to Decorative Patterns Derived from a Huizhou Chastity Archway, China

The digital preservation of architectural heritage often remains limited to static documentation, with insufficient support for the structured analysis and contemporary reuse of decorative patterns. This study proposes a shape grammar-based digital approach for analyzing, generat...

Steel surface defect detection based on dynamic receptive field and multi-scale features fusion

Abstract Steel surface defect detection is vital for guaranteeing product quality in contemporary manufacturing. However, traditional steel surface defect detection algorithms often face challenges due to insufficient resilience in feature extraction under complex backgrounds. To...

Dynamic mechanical behaviour of PVA micro-fibre rubber concrete under multi-factor effects

The dynamic mechanical properties of rubber concrete reinforced with polyvinyl alcohol (PVA) micro-fibres under the combined effects of high temperature, corrosive solutions and impact loading were investigated using split Hopkinson pressure bar tests and scanning electron micros...

Short-Term Ground Gust Prediction Based on Fusion of Ground and High-Altitude Meteorological Data and Differential Polynomial Modeling

Accurate Short-term forecasting of gusts at 10 m above ground level is challenging because gridded meteorological variables exhibit persistence, nonstationarity, and abrupt transitions. This study proposes a Temporal Adaptive Difference Polynomial Network (TADPN) using 8760 hourl...
