We introduce a neuromorphic architecture devised by mapping biologically inspired concepts onto a computational framework for self-awareness, offering a new way to embed inherent autonomy directly within hardware. Leveraging this architecture as a blueprint, we have designed a memristor-based circuit capable of autonomous decision-making, employing a bio-inspired hierarchical design approach. The core of this approach involves translating the functions of biological neurons and synapses into memristor-based circuits, which act as efficient computational units at the bottom layer of the circuit. It ensures that the developed circuit strikes a balance between functional flexibility and computational efficiency. Experimental results show that our implemented circuit provides efficient computational capabilities for effective decision-making, thanks to its memristor-based bio-inspired hierarchical implementation. Furthermore, its neuromorphic architecture inspired by self-awareness facilitates the easy simulation of reliable autonomous behaviors. Through the analysis of hardware overhead and power consumption, our circuit proves to be hardware-friendly. Our work represents progress towards developing memristor-based neuromorphic circuits characterized by high computational performance and autonomous functionality.

Extracting parameters accurately and effectively from solar photovoltaic (PV) models is crucial for detailed simulation, evaluation, and management of PV systems. Although there has been an increase in the development of analytical, numerical, and metaheuristic methods targeting this task, accurately determining these parameters continues to be a significant challenge. This study focuses on applying Particle Swarm Optimization (PSO) for the extraction of key parameters of RTC France solar cells, a critical step towards enhancing PV system efficiency and reliability. Additionally, the PSO's performance is evaluated against other metaheuristic algorithms including Enhanced Chaotic JAYA (CJAYA), Performance-Guided JAYA (PGJAYA), and Enhanced Gradient-Based Optimizer (EGBO), underscoring the effectiveness of the proposed PSO-based approach. Utilizing MATLAB-SIMULINK, comprehensive analysis and results are presented, shedding light on the efficacy of PSO in addressing the intricacies of parameter extraction in PV systems. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Lithium-ion batteries are widely applied in sustainable energy conversion system. Consequently, it is of great research significance to accurately estimate the state of health (SOH) of batteries. To effectively model the input features at the spatial level, this article proposes a self-attention graph pooling convolutional network (SAGPCN) to estimate the SOH. The advantages of SAGPCN proposed in this paper can be reflected as follows: (1) The SAGPCN can consider node characteristics and graph topology, which focuses the attention on key parts of the graph. (2) The SAGPCN designs a self-attention mechanism to reserve significant nodes and delete secondary nodes, so as to optimize the network structure. A real-world dataset is adopted to evaluate the proposed battery SOH estimation approach in this paper. Experimental results represent that the estimation performance of the proposed SAGPCN is better than some data-driven SOH prediction approaches. © 2023 IEEE.

In the article., the antenna with a CPW (Co-Planar Waveguide) structure is presented in Sub-6GHz band. By using a cascade of rectangular and circular patches., which are surrounded by the ground of CPW structure., the antenna realizes the good performances of wideband and high gain. Moreover, the symmetrically coupling structure is introduced in the proposed antenna., which can greatly improve the bandwidth and gain., so that it can cover the needed bands of Sub-6GHz communication. In order to realize the directional radiation, a box-type reflector is used to achieve high gain. Finally., for comparison, the beneficial effects of the symmetric coupling structure on the performance of antenna concluding bandwidth and realized gain are verified. The simulated results present the directional gain of the planar antenna is 6.4-10.7dBi at 0.6 GHz-0.96 GHz., 1.7 GHz-2.7 GHz and 3.3 GHz-4.2 GHz. The antenna possesses several benefits, including broadband., high-directivity., and economical, making it a fitting choice for contemporary communication systems. © 2023 IEEE.

Cardiovascular diseases are a major global health challenge, with electrocardiography (ECG) being critical for diagnosis and monitoring. As artificial intelligence and automated ECG diagnostic technologies rapidly advance, the demand for large-scale ECG databases continues to grow. Generative ECG has become a mainstream method to enhance database size and diversity. However, existing methods typically generate ECG randomly or focus on limited physiological categories, lacking the ability to synthesize ECG with varying physiological features and cardiac cycles, which is crucial for various practical applications. In response to this need, we propose a novel approach introducing a diffusion model called DIFF-ECG to generate precisely customized ECG that accurately reflect diverse cardiac conditions. Segmentation-based quality assessments confirmed that the synthesized ECG accurately followed the specified cardiac cycle information, with our model significantly outperforming baseline diffusion and GAN-based methods. Therefore, our approach addresses the critical need for generating clinically relevant and customizable ECG, contributing significantly to the field of automated cardiac disease diagnosis. By enabling fine-tuning of cardiac cycle phases, our method significantly expands the application range of generative ECG, potentially improving the diagnostic accuracy for rare diseases and advancing personalized medicine.

This paper introduces a linearly polarized beam-deflection array that operates in the X-band and has a phase resolution of 1 bit. The transmission unit consists of three media layers and three metal layers. Its metal layers include metal strips with specific arrangements are used to twist the polarization of electromagnetic waves by ± 90°, and then the middle metal layer is rotated by 90° to form a phase difference of 0°/180°. A 20× 20 transmission array with beam deflection is designed using this unit. The designed antenna array shows good electrical characteristics including gain of 16 dBi at 11GHz and stable radiation patterns at both H- and V-planes. © 2023 IEEE.
