Head-mounted devices (HMDs) are developing rapidly and show a great demand for head-mounted gaze-tracking techniques. However, the lack of slippage robustness and excessive calibration time still bother current gaze-tracking systems. This article proposes STARE, a head-mounted real-time gaze tracking system with slippage-robust gaze estimation and minimal calibration. STARE leverages the eyeball kinematics, specifically Listing’s law and Donder’s law, to propose a mapping function for slippage robust gaze estimation that holds physical significance. Our succinct mapping function minimizes personal calibration time to its lowest. The experimental results of 40 subjects demonstrate that our system achieves a mean angular error of \u0000<inline-formula> <tex-math>${0}.{71}^{circ } $ </tex-math></inline-formula>\u0000 under varying levels of device slippage and decreases the personal calibration time to less than 1 s.

The 4-mercaptophenylboronic acid (PMBA) monolayer was self-assembled on the silver film surface in the sensor as the recognition layer. Meanwhile, 4-mercaptobenzoic acid (4-MBA)-modified gold nanoparticles (AuNPs) were adopted as the signal amplification tag to enhance the wavelength shift of the SPR phenomenon excited by the light transmitted in the wall of the HF sensor.

This approach fundamentally differs from conventional methods by the relative lateral motion between the target and the platform. Although super-resolution azimuthal imaging can be achieved, different orbital angular momentum (OAM) modes should be modulated in different signal pulses. In contrast, a new OAM modulation and monopulse imaging method is proposed in this article, which involves multiplexing OAM modes based on frequency diversity in one pulse and can considerably improve imaging efficiency. By introducing tiny frequency offsets among the elements of a uniform circular frequency diverse array (UC-FDA), the OAM multiplexing beams are generated. Subsequently, the EM vortex imaging model for the coherent UC-FDA is established, and the imaging method is proposed. The theoretical performance analyses of spatial azimuthal resolution and efficiency are derived. Finally, the results demonstrate that the proposed method exhibits comparable imaging performance to the conventional EM vortex imaging method, even when only a single pulse is transmitted.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"24 22","pages":"37061-37071"},"PeriodicalIF":4.3,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636435","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}

However, this type of detection method has strict requirements for secondary antibody incubation processes and analysis equipment, leading to strong demands for convenient, rapid, and inexpensive detection platforms. In this study, a mechanical competitive immunosensor (MCI) was proposed for the detection of human serum albumin (HSA) based on goat anti-rabbit @Fe2O3 magnetic beads with magnetic sensitization. With the doping of Fe2O3, the conversion layer of MCI responds more accurately and rapidly to stress. In addition, goat anti-rabbit conjugated with animated Fe2O3 nanoparticles were introduced as secondary antibodies for signal amplification. Under the synergistic effect of the magnetic force of magnetic beads and the stress caused by the specific binding of antigen and antibody, the deformation of the film was amplified, which can effectively change the conductive pathway formed by doped carbon nanotubes, resulting in a larger output electric signal. Through competitive immunoassay for HSA, a limit of detection (LOD) of 68 ng/mL was achieved, which was an order of magnitude lower than direct detection methods. With high reproducibility and stability, MCI demonstrated effectiveness in the detection of HSA at a clinically significant concentration range (0.1–\u0000<inline-formula> <tex-math>$50 ; mu $ </tex-math></inline-formula>\u0000g/mL).

However, the climate conditions in high-altitude areas pose challenges to the interruption performance of ACBs. This study focuses on ACBs and, based on the theory of magnetohydrodynamics (MHD), utilizes the finite element software Ansys Fluent to establish a 2-D dynamic arc simulation model. Simulation analyses are conducted at altitudes of 2, 3, 4, and 5 km. The findings reveal that as altitude increases, the average arc voltage decreases while the arcing time prolongs. In addition, the arc demonstrates faster movement before entering the arc-extinguishing splitter plates and slower movement afterward. Furthermore, through climate chamber simulation experiments, the arc current and voltage of the breaker in high-altitude environment are measured, and the erosion conditions of the arc-extinguishing splitter plates in post-test prototypes are used to validate the accuracy of the simulation model. The findings indicate that the simulation results are in good agreement with the experimental results. The construction of this simulation model helps compensate for the limitations of unclear observation of arc motion trajectories in experiments, facilitating the analysis of arc motion patterns and the identification of factors affecting the interruption performance of circuit breakers in different altitude environments. Thereby, this study can provide a theoretical basis and reference for the design of ACBs in high-altitude environment.","PeriodicalId":450,"journal":{"name":"IEEE Transactions on Plasma Science","volume":"52 8","pages":"3257-3269"},"PeriodicalIF":1.3,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142600341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then the impact of RONS distribution on the inactivation efficiency against Staphylococcus aureus (ATCC 25923) biofilm was analyzed. Experimental results demonstrated an influence of gas flow rates and treatment distances on RONS distribution.

At 5 mm, the RONS distribution showed a solid circular shape at 0.8 SLM and below, a double ring shape at 0.9 SLM, and a ring shape at 0.9 SLM and above. The total redox concentration exhibited a positive correlation with the three physical parameters. Biofilm was treated for 100 s at a vertical position of approximately 3 mm. The inactivation of biofilm by the jet was slightly more efficient at 0.4 SLM (RONS was characterized by a low concentration of solid circular shape) compared to 0.8 SLM (high concentration of ring shape).

However, for total-field OPMs in the Mz/Mx mode, radio frequency (RF) magnetic fields oscillating at different frequencies tend to cause crosstalk between adjacent sensors obviously. In this work, a scheme to reduce the RF magnetic field crosstalk between sensor units was investigated. First, the dependence of the Mz magnetometer sensitivity on the RF magnetic field and cell temperature was explored experimentally. To reduce the RF field, we optimized the cell temperature and set lower laser power.

Moreover, three types of coils consisting of the square Helmholtz coils, the biplanar X coils, and the biplanar Z coils have been deeply explored in terms of their stray fields. Compared to the other two kinds of coils, the stray field of biplanar Z coils drops more rapidly in the XOY-plane and the XOZ-plane. Specifically, the minimum spacing between adjacent sensors can be reduced from 23.87 to 10.10 cm if the RF magnetic field is generated by biplanar Z coils instead of the square Helmholtz coils, with crosstalk remaining below 0.1%.","PeriodicalId":447,"journal":{"name":"IEEE Sensors Journal","volume":"24 22","pages":"36627-36635"},"PeriodicalIF":4.3,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636483","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}
