Parameter-Efficient Time–Frequency Temporal Convolution with Log-Percentile Normalization for Underwater Acoustic MAC Protocol Recognition

Passive recognition of medium access control (MAC) protocols allows an underwater acoustic monitoring node to infer channel-access behavior without decoded control headers or cooperation from the observed network. This study evaluates a parameter-efficient time–frequency temporal...

Lithium-ion battery SOH estimation based on degradation physics constraints and cross-attention Transformer-GRU

Accurate estimation of lithium-ion battery state of health (SOH) is essential for battery management systems in safety warning, lifetime management, and energy scheduling. To address the difficulty of simultaneously capturing global feature coupling and local degradation memory w...

Experiment and Analysis of Emergence Based on Gaussian Cloud Model

The cloud model provides a unified mathematical framework for representing both randomness and fuzziness simultaneously, offering an effective mathematical tool for modeling complex systems. This paper focuses on the emergent phenomenon of spontaneous synchronous flashing in fire...

Network‐Structured All Organic Composite for High‐Temperature Capacitive Energy Storage

ABSTRACT High‐temperature dielectric polymers are promising for advanced power electronics and electrical systems but often suffer from thermally activated charge transport and breakdown under harsh operating conditions. Here, we demonstrate that high‐loading low‐molecular‐weight...
