This paper presents a high noise efficiency readout circuit for multi-channel bio-signal acquisition. The prototype is implemented in a 65 nm CMOS LP process, which achieves a power consumption of 2.06 $\mu$W/channel, a noise efficiency factor (NEF) of1.48, a common-mode rejection ratio (CMRR) of 105 dB at 50 Hz, and a crosstalk of -65dB by employing these new techniques, including 1) the use of single-ended amplifiers as the unit of low noise amplifier (LNA) for lower NEF, 2) single-end chopping techniques for single-ended amplifiers for suppressing low-frequency noise and offset, 3) digital-assisted DC servo loop (DDSL) for fast settling.

Joint Secure and Covert Communications for Active STAR-RIS Assisted ISAC systems

This paper investigates the design of jointly supporting physical layer security (PLS) and covert communications (CCs) in an active simultaneously transmitting and reflecting reconfigurable intelligent surface (a-STAR-RIS) assisted integrated sensing and communication (ISAC) system. Due to the unified waveform design of ISAC signals, we consider a challenging scenario with two targets being suspicious attackers, where one warden target potentially detects the confidential transmission behavior of covert users and another eavesdropper target attempts to intercept the broadcasted confidential information of security users. We investigate the joint beamforming design at the base station (BS) and the a-STAR-RIS to achieve a high-quality sensing beampattern while meeting covertness and security communication requirements. (1) For the ideal scenario with perfect channel state information (CSI) and precise target locations, we propose an alternative optimization (AO) method to address the optimization problem involving highly coupled variables. Specifically, the optimal beamforming design at the BS is handled using the semi-definite relaxation (SDR) technique, while the beamforming design at the a-STAR-RIS is addressed through a penalty-based iterative algorithm. (2) A more practical case with uncertain target locations and imperfect CSI is considered to achieve a robust beamforming design, where the non-deterministic outage probability constraints are effectively transformed by employing the Bernstein-type inequality. Numerical results demonstrate the superiority of the a-STAR-RIS over the baseline cases and certify that the proposed algorithms can effectively balance the tradeoff among the sensing quality, covert and secure communication requirements. Besides, results also show that the proposed robust beamforming scheme can construct adequate sensing beampattern, even with imperfect CSI and uncertain target locations. © 2002-2012 IEEE.

Optimal Resource Allocation for U-Shaped Parallel Split Learning

Split learning (SL) has emerged as a promising approach for model training without revealing the raw data samples from the data owners. However, traditional SL inevitably leaks label privacy as the tail model (with the last layers) should be placed on the server. To overcome this limitation, one promising solution is to utilize U-shaped architecture to leave both early layers and last layers on the user side. In this paper, we develop a novel parallel U-shaped split learning and devise the optimal resource optimization scheme to improve the performance of edge networks. In the proposed framework, multiple users communicate with an edge server for SL. We analyze the end-to-end delay of each client during the training process and design an efficient resource allocation algorithm, called LSCRA, which finds the optimal computing resource allocation and split layers. Our experimental results show the effectiveness of LSCRA and that U-shaped parallel split learning can achieve a similar performance with other SL baselines while preserving label privacy.

The research on the combustion stability of coal-fired power plant boilers is related to the safe operation and economic benefits of the boiler. The combustion stability judgement plays an important role for the assessment of flexibility retrofit with coal-fired power plants participating in deep peak-regulating operation. Therefore, the study of combustion stability judgment has always been a hot research direction. This paper briefly introduces the development history of boiler flame combustion stability research, and focuses on two popular research directions in this field in recent years, namely flame image combustion stability detection method and multiinformation fusion combustion Stability testing methods, briefly summarize the development trends of these two research directions and their respective advantages. Then, the current research status and problems in this field are put forward three aspects of thinking and suggestions. Finally, several problems that need to be solved in the future development of combustion stability research are summarized. © 2021 IEEE

Tactile displays have gained significant attention, particularly in the medical field for their application in Braille for the visually impaired. Traditional Braille embossing systems face limitations in terms of device size and complexity due to mechanical stimulation. Therefore, electro-tactile displays have emerged as a promising solution for implementing Braille. Our study presents a compact electro-tactile device with built-in electrodes, which is used to determine optimized stimulation parameters. We conducted tests on both polarity and intensity, culminating in a Braille number examination using 0.8mA, 1ms anodal stimulation. The results showed an average accuracy of 64.3% in seven participants, and three of them achieved over 90%.

Automating smart Internet of Things devices in modern homes using context-based fuzzy logic

Internet of Things (IoT) is mainly used to connect different embedded objects over the internet to make communication between them possible. With the help of IoT, devices find a way to interact, work together, and study from each other's experiences just like humans do. IoT finds its way in applications such as smart home, smart city, healthcare, agriculture, and so on. The name smart home arises due to the automation of the normal home appliances to make it smart. When the devices of the normal smart home are connected via the internet, they become a part of the IoT. The smart home should ensure the following characteristics such as security, comfort, convenience, and energy saving. The article presents a technique for IoT controlled devices in a smart home using context-based fuzzy logic. Fuzzy logic is mainly used to monitor and analyze the real-time data collected from the sensors in the smart homes from various environments. Context-based fuzzy logic uses a multivalued logic principle which differs from the normal Boolean logic, where the truth value lies between only zero and one (ie, true or false). The proposed smart home is implemented in a real case scenario where it yields an accuracy of 90.5%, response time of 6.41 milliseconds, and an F-measure of 97%. © 2020 Wiley Periodicals LLC.

Fast Reconstruction of Monocular Human Video Based on KAN

Creating 3D digital people from monocular video provides many possibilities for a wide range of users and rich applications. In this paper, we propose a fast, high-quality, and effective method for creating 3D digital humans from monocular videos, achieving fast training (2.5 minutes) and real-time rendering. Specifically, we use 3D Gaussian Splatting (3DGS), based on the introduction of Skinned Multi-Person Linear Model (SMPL) human structure prior, and an optimized KAN (Kolmogorov-Arnold-Net) neural network to build effective posture and linear blend skinning (LBS) weight estimation module to quickly and accurately learn the fine details of the 3D human body. In addition, to achieve fast optimization in the densification and prune stages, we propose a two-stage optimization method. First, the local 3D area that needs to be densified is extracted based on LightGlue, and then KL divergence combined with human body prior is further used to guide Gaussian splitting/cloning and merging operations. We conducted extensive experiments on the ZJU MoCap dataset, and the Peak Signal-to-Noise Ratio (PSNR) and Learned Perceptual Image Patch Similarity (LPIPS) metrics indicate that we effectively improved rendering quality while ensuring rendering speed. © 2025 IEEE.
