However, conventional commercial sensors are typically rigid, constrained by narrow relative humidity (%RH) operating ranges, and require complex fabrication processes. In this study, we present a highly sensitive cubic silicon carbide (3C-SiC) nanoparticle-based relative humidity sensor, fabricated via serigraphic printing on to 5 mil thick flexible polyimide (Kapton®) substrate. Devices are tested across a broad humidity range of 10-90%RH at ambient temperature and their performance is evaluated in a controlled humidity chamber. The sensor exhibits a robust response of 45.2% R/R0, with a sensitivity of 5.34 Ω/%RH, an adsorption time of 18 seconds, and a desorption time of 46 seconds. Additionally, the device demonstrates low hysteresis of 6.5% at 60%RH, with excellent repeatability and stability over 3.5 hours of continuous cycling. To showcase their potential for real-world applications, the printed sensors are integrated into a commercial KN95 mask for monitoring respiration parameters, such as respiration rate. This integration highlights the potential for future exploration in human health monitoring, utilizing fully printed, low-cost sensing devices.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"4 1","pages":"96"},"PeriodicalIF":0.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144164040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional models, limited to steady-state conditions, lack predictive accuracy for clinker mineralogical phases. Here, using a comprehensive two-year industrial dataset, we develop machine learning models that outperform conventional Bogue equations with mean absolute percentage errors of 1.24%, 6.77%, and 2.53% for alite, belite, and ferrite prediction respectively, compared to 7.79%, 22.68%, and 24.54% for Bogue calculations. Our models remain robust under varying operations and are evaluated for uncertainty and rare-event scenarios. Through post hoc explainable algorithms, we interpret the hierarchical relationships between clinker oxides and phase formation, providing insights into the functioning of an otherwise black-box model.

This method provides a spectrally efficient training-free solution for estimating 3D underwater positions. The system remains effective despite high water turbidity with a relatively low impact on marine life compared to similar acoustic methods. Pisces is less complex, computationally efficient, and uses less power than camera-based solutions. Pisces enables robust relative localization, especially in swarms of robots with the potential for additional applications like docking. We demonstrate high localization accuracy with a Mean Absolute Error (MAE) of 0.031 m at 0.32 m separation and 0.16 m MAE at 1 m separation. Moreover, it achieved this with minimal power consumption, utilizing only 11 mA of transmitter LED current and performing 3D localization within 10 ms for distances up to 3 m.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"4 1","pages":"93"},"PeriodicalIF":0.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12102152/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144133143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we formulate a localization method based on the special properties of rotating magnetic dipoles, which allow reconstruction of position and rotation axis from a single external tri-axial magnetometer. The rotating dipole is realized through a permanent magnet synchronous motor (PMSM) that can reversibly (un)lock using the heat-induced phase transition of a low melting point alloy. Sequential localization and manipulation is performed by an external mobile electromagnet equipped with a single eye-in-hand Hall effect sensor. We describe the PMSM's thermal and magnetic properties, formulate the governing localization equations, quantify and validate 3D tracking of PMSM pose trajectory, and demonstrate sequential localization and manipulation in a benchtop experiment.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"4 1","pages":"91"},"PeriodicalIF":0.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12098917/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144129593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, large-scale quantum transport simulation remains a challenging field, making it difficult to account for quantum mechanical effects arising from the complex device geometries. Here, based on large-scale quantum transport simulations, we demonstrate that quantum geometrical effects in stacked nanosheet GAAFETs significantly impact carrier injection characteristics. Discontinuities in confinement energy at the constriction-the junction between the bulk source/drain and nanosheet channel-cause substantial carrier backscattering. This degradation becomes more severe as electrons experience higher effective energy barriers, and is further exacerbated at lower scattering rate, lower doping concentrations, and near Schottky barriers where electron depletion regions form. Considering these quantum mechanical bottlenecks, proper device optimization for future technology nodes requires a full quantum-based device structure design at the large-scale level, which enables unique optimization strategies beyond conventional classical prediction.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"4 1","pages":"92"},"PeriodicalIF":0.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12098892/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144128408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work introduces EQS car body communication, recognizing the potential of the car's chassis as a medium to confine EQS fields. This alternative approach offers a new modality for efficient intra-vehicle wireless communication, addressing power efficiency and physical security concerns. Furthermore, this research demonstrates that a vehicle can be treated as a resonant cavity, providing low-loss, wideband channels for high-speed communication. Theoretical analysis, electromagnetic simulations, and measurements conducted in a consumer-grade vehicle highlight the viability of these new intra-vehicle communication techniques.

The technology has evolved since its inception when it used analogue film exposure techniques with the introduction of digital imaging systems sensitive to ionizing radiation. We report on the development of our Quantitative Particle Identification spectral autoradiography system (QPID), which is based on the Timepix3 sensor and a gamma detecting scintillation crystal. This autoradiography system leverages the ionizing radiation detection features of the Timepix3 to measure the energy deposition from charged particles from radioisotopes with a time resolution of 7.7 ns full width at half max (FWHM), generating spectral or activity autoradiography images. The QPID includes a scintillation crystal used to record gamma emissions coincident with the Timepix3 ionization events with a time resolution of 24.2 ns FWHM. The QPID can separate tracks between α and ß particles, select specific ranges of deposited energies or select on the presence of coincident gamma emissions within a selected energy range when generating images. The QPID has a 10% linearity response up to 700 Bq for 223Ra and 2.5 kBq for 18 F radioisotopes. Using α and ß+ particle identification filters, separate images of 223RaCl2 and Na18F activity distributions were generated from a bone sample infused with the two radioligands together. This unique capability can open the door to the study of targeted radiotherapies which use theranostic α and ß+ imaging agents by measuring their relative pharmacokinetic properties.","PeriodicalId":72644,"journal":{"name":"Communications engineering","volume":"4 1","pages":"89"},"PeriodicalIF":0.0,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12081844/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
