IPv6 over the time-slotted channel hopping (TSCH) mode of IEEE 802.15.4e (6TiSCH) networks, based on the IEEE 802.15.4 time-slotted channel hopping (TSCH) MAC mode, provides high reliability and energy efficiency. However, the default scheduling function (SF) in 6TiSCH, the minimal SF (MSF), suffers from overprovisioning issues, leading to inefficient timeslot utilization and traffic throughput limitations in high-density, high-traffic network environments. To address these challenges, we propose adaptive scheduling with cell borrowing for improving traffic throughput in dense 6TiSCH networks (ASCBT). ASCBT introduces three mechanisms that allow sibling nodes to borrow and utilize overprovisioned cells, reducing timeslot resource waste and improving the network’s maximum traffic throughput. Additionally, it effectively adapts to fluctuating traffic conditions. Performance evaluations in high-traffic scenarios show that ASCBT achieves up to 20.2% higher packet delivery ratio (PDR) and 23.8% lower end-to-end latency compared to MSF under constant-rate and burst traffic scenarios. These results indicate that ASCBT effectively enhances traffic handling capacity and network stability in large-scale TSCH-based IIoT networks.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"20813-20828"},"PeriodicalIF":4.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144196550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is very important to detect Pb2+ in high throughput, accurately and specifically. Fluorescent sensors have obvious advantages in heavy metal detection. In comparison with the bulk phase, graphite-phase carbon nitride nanosheets (g-CNNs) of atomic thickness and nanometer size can conspicuously improve the quantum yield and water solubility. The aptamer offers the benefits of exceptional specificity, robust stability, minimal toxicity, cost-effectiveness, straightforward synthesis and modification, and absence of immunogenicity. In this study, an high throughput signal-off-on fluorescent aptasensor was designed for detecting Pb2+ on the basis of fluorescence resonance energy transfer (FRET) mechanism between gold nanoparticles (AuNPs) and g-CNNs.

To overcome these obstacles, a comprehensive study delves into gas-liquid two-phase flow utilizing a monocular Stereo-PIV system. To reduce the need for high-precision target localization, a method is proposed that integrates particle features for corner extraction and spatial consistency for precise matching by pyramid up-down sampling. The approach effectively mitigates scale variance-induced mismatches and facilitates accurate spatial plane reconstruction. Validation is conducted utilizing particle simulation to assess the accuracy of feature extraction and matching and their impact on spatial plane reconstruction. Furthermore, optical distortion calibration results derived from gas-liquid two-phase flow are compared with experimental data to investigate the accuracy of real plane reconstruction. The accuracy of 3-D velocities is evaluated across planes with various errors. Finally, 3-D velocity profiles are characterized within slug flow structures, thereby offering insights into velocity variation characteristics.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"20104-20112"},"PeriodicalIF":4.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144206149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strong localization of modal fields at the truncated silicon tip interface results in fine resolution below the diffraction limit. It is found that, at a specific probing distance, high conductance of a metallized sample exhibits lower reflection than bare silicon substrate due to the signal cancellation with the reflection generated from the significant mismatch at the truncated interface. We experimentally validate that this cancellation effect is dependent upon conductivity and it allows us to differentiate multiple levels of conductivity. With this technique, we achieve the resolution of ~1/<inline-formula> <tex-math>$3~lambda _{{0}}$ </tex-math></inline-formula> and a high image contrast of ~20 dB between conductors and the bare silicon substrate. In addition, a cancellation effect is employed that allows for accurate calibration of working distance, providing stable responses across the scanning area. We demonstrate how this effect can be exploited for high-accuracy material classification with broadband spectral correlation analysis enabled by the silicon sensor. The proposed method can be easily incorporated with integrated all-silicon circuits, showing promise for cost-effective, compact imaging modules, which is highly beneficial for real-world deployment in the industry.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"20648-20657"},"PeriodicalIF":4.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10976487","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the minimal impact of small hydrostatic pressure on ordinary silica optical fibers, research on its measurement utilizing optical fiber sensing technology remains limited. In this article, a novel microwave photonics technique, termed optical carrier-based microwave interferometry (OCMI), is utilized for small hydrostatic pressure sensing with the assistance of a convolutional neural network (CNN). The theory of OCMI-based phase demodulation is established, and numerical simulations are conducted to investigate the factors affecting the axial displacement of the fiber core. In practical experiments, the phase demodulation method is applied to small hydrostatic pressure measurements; however, the results are suboptimal. Therefore, the CNN is developed to assist in the implementation of accurate small hydrostatic pressure sensing. The small hydrostatic pressures predicted by the well-trained CNN model are in good agreement with the actual values, with an error of less than 0.25 kPa. In addition, the prediction results from multiple Fabry-Perot interferometers (FPIs) demonstrate the feasibility and effectiveness of utilizing CNN for OCMI-based small hydrostatic pressure sensing. The introduction of machine learning broadens the application scope of the OCMI technique, allowing it to be employed for distributed sensing of a wider range of physical, chemical, and biological quantities.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"20948-20955"},"PeriodicalIF":4.3,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144196551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A major challenge is to avoid false target positioning in multitarget positioning scenarios. Besides, a reasonable probable target area model is also critical to the accuracy of positioning and counting targets. In this article, a novel passive localization scheme is proposed to locate multiple targets. This scheme introduces a rectangular probable target area model, which is used to calculate a rectangular area containing the potential location of the target to be located. Compared with existing models, it is more suitable for positioning scenarios under low-density deployment of sensing nodes. Furthermore, we present an improved successive cancellation (SC) algorithm to excluding false target localization. To determine the authenticity of targets by the SC algorithm, a Bayesian model is introduced to optimize the SC algorithm according to the multidimensional shadowed link information of candidate targets. Numerous simulation results show that the proposed multitarget passive localization scheme can improve the problem of false target localization in multitarget localization scenarios. And it also can achieve outstanding performance in localization accuracy.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"25 11","pages":"20037-20050"},"PeriodicalIF":4.3,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This excellent selectivity and significant sensor response to H2 make it well-suited for leak-detection applications.
