The computational inefficiency of spiking neural networks (SNNs) is primarily due to the sequential updates of membrane potential, which becomes more pronounced during extended encoding periods compared to artificial neural networks (ANNs). This highlights the need to parallelize SNN computations effectively to leverage available hardware parallelism. To address this, we propose Membrane Potential Estimation Parallel Spiking Neurons (MPE-PSN), a parallel computation method for spiking neurons that enhances computational efficiency by enabling parallel processing while preserving the intrinsic dynamic characteristics of SNNs. Our approach exhibits promise for enhancing computational efficiency, particularly under conditions of elevated neuron density. Empirical experiments demonstrate that our method achieves state-of-the-art (SOTA) accuracy and efficiency on neuromorphic datasets. Codes are available at https://***/chrazqee/MPE-PSN.

Recently, there has been increasing information about the removal of chemical pollutants through biochar and intermittent aeration. However, little attention was paid to the application of biochar and intermittent aeration for the improvement of antibiotic resistant bacteria (ARB) removal in stormwater bioretention cells. Target ARB (E. coli K-12 carrying blaTEM, tetR and aphA) was used in batch experiments for bioretention cells with different biochar content, ratios of air to water (A/W) and aeration time (AT). ARB removal decreased with the increase of M/B in bioretention cells, where the highest ARB removal (3.73 Log) was found under 10% of biochar, while intermittent aeration could contribute to the enhancement of ARB removal with the largest (3.94 Log) under A/W of 40:1 and AT of 4 hr/d. Both biochar chemisorption and H2O2 oxidation were responsible for ARB removals with the maximal adsorption capacity of 33843 CFU/g, and the highest ARB removal of 1.00 Log due to H2O2 yields (0.021-0.042 mmol/L). ARGs conjugation frequencies tended to decrease with the increase of biochar levels and AT, and ARGs transformation decreased obviously under A/W of 40:1 and 20:1. There were around 1.13-fold changes for both intracellular reactive oxygen species (ROS) and cell membrane permeability (CMP) in bioretention cells with the combination of biochar and intermittent aeration, suggesting the slightly increasing risks for both conjugation and transformation when the application of the combined method on ARB removals. © 2025, The Authors.

The application of Consumer-Centric Wireless Medical Sensor Devices in the medical field has brought great convenience to doctors and patients. However, the transmission process may compromise patient privacy, making the authenticity and integrity of medical data a significant challenge in the healthcare industry. To address this issue, a certificate-less Healthcare Signature scheme is proposed to protect patient privacy. However, most schemes are unable to resist fully selective cipher text attacks and suffer from key exposure problems. To mitigate these issues, a scheme is proposed to resist fully selective attacks in real-time processing of Consumer-Centric Wireless Medical Sensor Devices with high latency issues, while utilizing parallel key isolation methods to address key exposure problems. The scheme's enforceability is proven based on the random oracle model and the computational Diffie-Hellman assumption, and its resistance to fully selective key attacks is proven based on hash-based collision resistance. It is shown that this plan works well for wireless sensor networks in the medical field. Sensor nodes have limited resources, and sending vast volumes of patient medical data online significantly raises processing and communication costs. The low processing power of edge devices limits the effectiveness and performance of medical services. Efficiency analysis using the MIRACL library demonstrates that the proposed scheme outperforms other relevant schemes in terms of efficiency at each stage, while also having lower communication overhead. © 1975-2011 IEEE.

The emergence of low-latency wireless connectivity has opened significant new possibilities for closed-loop human-machine interaction (HMI) systems. However, data transmission, particularly over wireless links, suffers from impairments, such as random latency fluctuations and packet loss, affecting the overall control performance of HMI systems. In this study, we have evaluated the impact of wireless impairments for a closed-loop joystick-controlled trajectory tracking task. This has been done with two different types of feedback, visual and tactile, respectively. Wireless links were used both in the uplink transmission of command signal and the downlink transmission of feedback signal. The effects of wireless impairments were incorporated by artificially introducing latency, jitter, and packet loss recorded in real-life deployment scenarios, both in the uplink and the downlink. The results obtained across 12 able-bodied participants showed that the tracking performance was better with visual feedback than with tactile feedback across all impairment conditions. The average latency significantly affected performance, while random latency fluctuations did not. Interestingly, the performance degradation due to increasing impairments in case of tactile feedback was similar to the one observed for visual feedback. One of the main novelties brought by this study is the quantification of the impact of wireless impairments on closed-loop teleoperation tasks with tactile feedback. The results provide valuable insights for designing wireless infrastructure for tactile internet applications. © 2008-2011 IEEE.

The 21st century has already witnessed so many outbreaks with pandemic potential, including SARS (2002), H1N1 (2009), MERS (2012), Ebola (2014), Zika virus (2015), and the COVID-19 pandemic (2019). Using 60 million geotagged Sina Weibo tweets covering over 20 million active accounts, we investigate the collective emotional dynamics on social media in the most recent global pandemic, i.e., COVID-19. This research features two highlights: (1) It focuses on the Chinese population located in the initial epicenter of the pandemic. (2) It examines the initial year after the pandemic outbreak, a critical period where emotions were most intense due to the uncertainty and rapid developments related to the crisis. Using cross-disciplinary methods, we reveal a positive connection between online emotional resonance and geographic proximity, demonstrating a direct mapping between virtual network distances and physical spatial embedding. We propose a percolation-based index to measure the nationwide emotional resonance level with which we illustrate the significant economic impact of the global health issue. Finally, we identify a leader-follower pattern in emotional resonance fluctuations based on time-lag emotion correlations, revealing that less active regions play a crucial role in leading and responding to emotional changes. In the face of long COVID and emerging global health crises, our analysis elucidates how collective emotional resonance evolves, providing potential directions for online opinion interventions during global shocks. © 2025 Copyright held by the owner/author(s).

IEEE Transactions on Vehicular technology 2025年

As a pivotal technology for sixth-generation (6G) mobile networks, semantic communication (SC) aims to enable low-energy, high-efficiency intelligent communication through joint source-channel coding (JSCC). However, current multimodal SC systems experience semantic divergence and conflicts due to imbalances in the representation capacity of individual encoders. Furthermore, high computational demands significantly elevate the deployment and operational costs of SC. In this letter, we propose a multimodal-oriented lightweight SC system based on an interactive JSCC scheme, promoting the evolution of 6G towards a multi-source collaboration paradigm. Additionally, a dynamic resource allocation method is introduced, which hierarchically adjusts computational costs to improve efficiency. Simulation results demonstrate that the proposed system reduces computational overhead by 60\% compared to six benchmarks while maintaining high performance and robustness in multiple tasks. © 1967-2012 IEEE.

This paper presents a multifunctional flexible absorber/reflector with wideband performance and low power consumption. The proposed unit cell utilizes only two PIN diodes to achieve four distinct functions with low power consumption. By integrating the metal structure of the unit cell with the PIN diode bias lines, the design is simplified. In addition, the physical characteristics of the proposed structure are thoroughly analyzed using equivalent circuit theory, electric field analysis, and surface current distribution, enhancing the understanding of the design mechanisms. The simulation and experimental verification results are in agreement. Four distinct functions are successfully demonstrated within the frequency band of 8.5 GHz - 12.5 GHz, with a maximum power consumption of only 0.078 W. © 2002-2011 IEEE.

While doping and defects are often considered detrimental to material performance, at the nanoscale, modifications are needed to create novel properties beneficial for device applications. In this work, we focus on optimizing Graphene as a gas sensor for detecting toxic gases such as Nitrogen Oxide (NO). The study explores the effects of doping Graphene sheets with transition metals (Cu, Au, Pt) and introducing a Single Vacancy (SV) defect at the center of the sheet. Pristine, defected, and doped Graphene sheets are systematically analyzed as potential sensing materials for NO gas detection. The investigation includes the design of Graphene-based devices and evaluation of their electrical I-V characteristics under different configurations. The sensing mechanism is examined through parameters such as electronic properties, charge transfer, adsorption energy, electrical characteristics (I-V), sensitivity, and the Non-Equilibrium Green’s Function (NEGF) approach. The results indicate that defected Graphene demonstrates superior gas adsorption performance, with an adsorption energy of 8.316 eV and a sensitivity of 51.1%, outperforming both pristine and doped Graphene. These findings establish defected Graphene as a promising candidate for NO gas sensing applications, while doped Graphene shows moderate sensing potential. Copyright © 2025, The Authors.
