Traditional detection methods often rely on bulky and power-hungry equipment, limiting their practicality for continuous monitoring. As\u0000 such, there is a growing demand for lowpower, high-performance sensing technologies to enable wearable or implantable epilepsy detection devices. In this context, the development of a latch-based SRAM sense amplifier presents a promising avenue for achieving both sensitivity and power efficiency\u0000 in seizure detection systems. The proposed latch-based SRAM sense amplifier architecture is meticulously designed to meet the specific requirements of epilepsy detection applications. Leveraging advanced semiconductor technologies and circuit design techniques, we optimize the sense amplifier’s\u0000 performance parameters, including sensitivity, speed, and power consumption. Through extensive simulations using industry-standard tools, we evaluate the sense amplifier’s performance under varying conditions, such as input signal amplitude, frequency, and power supply voltage. Additionally,\u0000 we compare the proposed architecture with existing solutions to assess its superiority in terms of both performance and energy efficiency. Our analysis reveals that the developed latch-based SRAM sense amplifier exhibits superior sensitivity to subtle signals associated with epileptic activity\u0000 while consuming significantly less power compared to conventional designs. The sense amplifier demonstrates rapid response times, enabling real-time detection and timely intervention in seizure events.

However, existing segmentation methods fall short due to image complexities and ambiguities. Recent advancements in deep learning show promise, but they rely on color images,\u0000 not thermal ones. This research introduces an automated, robust, and precise diabetic foot segmentation approach using a deep neural network based on U-Nets and modified Swin transformers. The unique attention mechanism known as the axial attention parallel module (A2PM) is combined with the\u0000 Unet-based Swin transformer model for an efficient segmentation process to extract local foreground features. The combination of the modified Swin Transformer’s multi-headed attention networks enhances thermal color information integration, resulting in superior segmentation accuracy.\u0000 In addition, the proposed model makes use of the stacking dilated convolution (SDC) approach to protect the deep features that could be lost in the up-sampling modules. The feature maps are immediately integrated at the encoder and decoder stages using the shortcut connection (ResConv route)\u0000 based on the residually connected convolutional layer. Furthermore, this ResConv path is added serially before the encoder and decoder characteristics are combined. The model is tested on 124 diabetic and 100 healthy subjects, evaluating its performance with metrics like DICE, IoU, precision,\u0000 and recall.

LTE (Long-Term Evolution) networks demand efficient antennas to support high-speed data transmission, while UWB (Ultra-Wideband) systems require antennas capable of\u0000 operating across a broad spectrum. Monopole antennas have emerged as promising candidates for meeting these demands due to their compact size and versatility. In this study, we delve into the design and analysis of dual monopole antennas, tailored to cater to both LTE and UWB applications,\u0000 with variants optimized for narrow and wide bands. The methodology adopted in this study involves a systematic approach to antenna design and analysis. Initially, the design parameters are carefully chosen to meet the frequency requirements of LTE and UWB systems, considering both narrow and\u0000 wide band variants. Advanced simulation tools are employed to optimize the antenna geometry and ensure impedance matching across the desired frequency bands. Additionally, rigorous electromagnetic analysis techniques are utilized to evaluate radiation characteristics, including antenna gain,\u0000 directivity, and radiation efficiency. Through iterative refinement and optimization, the performance of the dual monopole antennas is systematically enhanced to meet the stringent requirements of LTE and UWB applications. The results of our study demonstrate the efficacy of the proposed dual\u0000 monopole antennas for LTE and UWB applications. The good agreement is observed in the measured and simulated return loss with a narrow bandwidth of 0.45 GHz (1.65 to 2.10 GHz) for LTE band and a wide bandwidth of 12.42 GHz (4.74 to 17.16 GHz) for UWB applications.","PeriodicalId":16446,"journal":{"name":"Journal of Nanoelectronics and Optoelectronics","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141716214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
