With the start of the 5G operations, it will become more important to apply communication systems to automo-biles, which has been promoted in recent years as connected cars. Multi-band antennas are required to reduce the in-vehicle space which is occupied by communication equipment. We de-signed dual-band antennas for the sub-6 GHz 5G bands and the intelligent transport systems (ITS) especially the driving safety support system (DSSS) by loading helical elements to modified conical antennas (MCA), and conducted simulations and meas-urements. As a result, the antenna satisfied the sub-6 and ITS DSSS bands in the simulations. There were slightly differences between the calculated and measured results. © 2022 IEEE.

We sought to revolutionize the classification of Attention-Deficit/Hyperactivity Disorder (ADHD) by pioneering an innovative approach that seamlessly integrated auditory and visual tests with electroencephalogram (EEG) coherence analysis, forming the foundation for our Support Vector Machine (SVM) models. Our primary objective was to achieve precise differentiation between individuals with ADHD and those without, aiming to reshape the landscape of ADHD diagnosis and early intervention. We constructed an SVM model based on CATA coherence, incorporating a carefully selected set of 180 features, and another grounded in CPT coherence with 70 features. Astonishingly, our exploration uncovered that a model incorporating CATA's coherence and Power Spectral Density (PSD) as features achieved an astounding accuracy rate of 97.7%, using only half the number of features. This revelation hints at untapped potential for multivariate advancements in the realm of ADHD classification. The landscape of ADHD diagnosis and intervention is perpetually evolving, most notably with the FDA's approval of game therapy for ADHD. Leveraging the transformative power of our findings, we envision the development of user-friendly game therapies for in-home use, empowering both clinicians and parents alike. This marks a paradigm shift in the realm of ADHD intervention, offering objective, data-driven tools for the early management of ADHD. Gamified therapy not only enhances accessibility but also fosters engagement and compliance, all of which are pivotal in the long-term care of individuals with ADHD. In summary, our study represents a significant advancement in our comprehension and classification of ADHD. By fusing auditory and visual tests with EEG coherence analysis, fortified by state-of-the-art machine learning techniques, we have achieved an unprecedented level of accuracy in identifying individuals with ADHD. Our findings, aligned with the FDA-approved game therapy, offer a glimpse into a

Wide-field magnetic microscopy using nitrogen-vacancy (N-V) centers in diamond can yield high-quality magnetic images of dc and ac magnetic fields. The unique combination of micron-scale spatial resolution of scalar or vector fields at room temperature and parallel camera readout make this an appealing technique for applications in biology, geology, condensed-matter physics, and electronics. However, while N-V magnetic microscopy has achieved great success in these areas, historically the accessible frequency range has been limited. In this paper, we overcome this limitation by implementing the recently developed technique of quantum frequency mixing. With this approach, we generate wide-field magnetic images of test structures driven by alternating currents up to 70 MHz, well outside the reach of dc and Rabi magnetometry methods. With further improvements, this approach could find utility in hyperspectral imaging for electronics power-spectrum analysis, electronics diagnostics and troubleshooting, and quantum computing hardware validation.

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

To meet the demands of data-intensive applications such as artificial intelligence (AI) and high-performance computing (HPC), there is a need for tighter integration to minimize electrical interconnect delays and energy [1] . Typical I/O pitches for μ-bumps range from hundreds of microns to $\sim 50\mu \mathrm{m}$ for conventional flip chip bonding therefore limiting the number of I/O's. When scaling down solder-based μ-bumps, adjacent interconnects could be shorted during the bonding process. As a result, the investigation of new bonding techniques has become more and more popular. The feasibility of a 3D bonding technology for ultra-dense input/output (I/O) interconnects using cobalt selective atomic layer deposition (Co ALD) was explored with a preliminary testbed [2] .

Industrial automation systems use distributed computing architecture, comprising industrial networks with a wiring bus that is standardized to integrate their devices and monitoring process. A number of technologies, in a wide range of application levels, must operate in hostile environments, with high temperatures, humidity and magnetic interference. The Industry 4.0 applications requires that the communication infrastructure provide "last mile" communication services with a high level of reliability, which may increase costs and complexity of that infrastructure. Within such scenario, there is a growing demand for simpler and robust systems for monitoring and supervision of industrial processes. Powerline communication (PLC) is one of such systems that could provide ease of use and maintenance, since it uses the power system for serial digital data communication. This system has been commonly used in home applications, but it carries a great potential for the management of an industrial plant. Here, we present a new concept for the hardware, which collects field signals with PLC for industrial applications, using a Commercial-Of-The-Shelf (COST) modem. Three different setups have been performed, for a specific application that could be integrated to any industrial computer. The system has been experimentally evaluated in severe industrial environments, considering different noise levels, and provided reliable communication.

In the current display electronics, a high-resolution pixel density and refresh rate ranging 7680 × 4320 pixels, 300 ppi, and 240 Hz are in high demand. The pixel-driving Thin–Film Transistors (TFTs) are primarily responsible for the switch in such displays. The amorphous Indium-Gallium-Zinc-Oxide (a-IGZO) TFTs are popular in realizing better high–speed properties in line to achieve those needs. In previous years, amorphous-IGZO channel TFTs in one-gate and dual-gate structures have exhibited improved gate control. In this paper, the authors present the analytical performance of double–gate tri-layer channel structure design of a-IGZO TFT with three stacked channel layers (IGZO/ITO/ITO1) to model and evaluate the device performance at different gate biasing. The proposed device simulation results were encouraging, in terms of high capacitance in dual gate bias (CDG) 26.2 nF/cm2, high mobility (µFE) 16.93 cm2/V.s, and steeper subthreshold swing (SS) 95 mV/decade. © 2023, The Authors.
