This study proposes a novel method based on Reliability Enhancement Testing (RET) to induce potential defects in MEMS gas sensors. An experimental profile was designed based on RET theory, and failure stimulation was performed on MEMS gas sensors with multi-layer structures. The results show that this method has an extremely good defect activation effect on MEMS gas sensors. Further fault localization and failure analysis indicated that fatigue cracks in the gas-sensitive film were the primary cause of MEMS gas sensor failures, with these cracks being significantly related to residual stresses within the film and differences in thermal expansion coefficients of different layer materials. This research is expected to provide new technical pathways for reliability optimization of similar MEMS gas sensors during the development phase.

To fulfill the requirements of human lunar exploration programs and establish bases on the moon in the distant future, lunar sensors (LSs) will inevitably produce a significant amount of data. It is necessary to construct the Earth-Moon metaverse in order to obtain and utilize lunar information more effectively. Due to the long communication distance between Earth and Moon as well as the lack of communication resources, a hybrid Earth-Moon metaverse network with channel model and transmission model is designed. To ensure the efficiency and stability of transmission in the network, LSs transmit lunar data to Earth clients (ECs) through the active and passive intelligent reflecting surface (IRS) deployed at relay satellites. Then, we propose a Stackelberg game model to describe the adversarial relationship between the satellites, LSs and ECs, and optimal strategies are obtained by solving the Nash equilibrium to maximize their utility. Simulations demonstrate that the network can effectively shorten the transmission delay and improve the utility of ECs and satellites. © 2024 IEEE.

The output signal components of the sensitive end of micro-electro-mechanical system (MEMS) gyroscope are complex, and the design error of the back-end demodulation circuit can greatly affect the detection accuracy of the gyroscope. Therefore, this paper designs a high-precision signal demodulation scheme applicable to MEMS gyroscope sensors. The scheme improves the traditional signal demodulation technology by combining the correlation demodulation technology and the fast Fourier transform (FFT) technology, and after the correlation demodulation of the gyroscope-sensitive signal, the infinite impulse response (IIR) filter and the FFT transform are used to jointly extract the amplitude information of the fundamental frequency signal and do the fusion processing, so as to achieve the very high precision extraction of the input angular velocity. The feasibility of the demodulation scheme is verified by field programmable gate array (FPGA) simulation. The experimental results show that the combined IIR and FFT filtering algorithm has higher demodulation accuracy than the single low-pass finite impulse response (FIR) filtering algorithm. © 2022 IEEE.

The interlayer hybridization(IH)of van der Waals(vdW)materials is thought to be mostly associated with the unignorable interlayer overlaps of wavefunctions(t)in real ***,we develop a more fundamental understanding of IH by introducing a new physical quantity,the IH admixture ratioα.Consequently,an exotic strategy of IH engineering in energy space can be proposed,i.e.,instead of changing t as commonly used,αcan be effectively tuned in energy space by changing the on-site energy difference(2Δ)between neighboring-layer *** practice,this is feasible via reshaping the electrostatic potential of the surface by deposing a dipolar overlayer,e.g.,crystalline *** first-principles calculations unveil that IH engineering via adjusting 2Δcan greatly tune interlayer optical transitions in transition-metal dichalcogenide bilayers,switch different types of Dirac surface states in Bi_(2)Se_(3)thin films,and control magnetic phase transition of charge density waves in 1H/1T-TaS_(2)bilayers,opening new opportunities to govern the fundamental optoelectronic,topological,and magnetic properties of vdW systems beyond the traditional interlayer distance or twisting engineering.

Aiming at the problem that the amplitude of load oscillation is not easy to control in the movement process of overhead crane, this paper designs a switching PID control method based on whale optimization algorithm(WOA) to improve the performance of position control and anti-swing control for overhead crane. WOA is used to better adjust the parameters of PID controllers. The switching control is realized by a switching module, which defaults to the output of the Position PID Controller to provide control force for the trolley. When the absolute value of the load swing angle fed back by the crane system exceeds the warning value, the switching module immediately blocks the output of the Position PID Controller, and uses the Angle PID Controller to determine the control force. In addition, through theoretical analysis and simulation experiments under different conditions, the results verify the effectiveness of the WOA based switching control in position control and anti-swing control for overhead crane. Improve the efficiency and safety of overhead crane in practical industrial applications. © 2023 Technical Committee on Control Theory, Chinese Association of Automation.

DNS completes the resolution of domain names to IP addresses, which is an effective means to realize various In-ternet applications, and is also an indispensable part of Internet infrastructure, playing an important role. However, the resolution efficiency and security of DNS have always been a hot spot in the industry. This study deeply discusses the principle of Blockchain-based DNS resolution and conducts extensive re-search on Blockchain-based DNS resolution schemes. Based on compatibility with traditional DNS, these schemes are divided into two categories: compatible and incompatible. For different scenarios, we conduct a detailed analysis and comparison, focusing on the technical characteristics and performance of each so-lution. Finally, the future research direction is looked forward to, and the full text is summarized. © 2023 IEEE.

Effective non-invasive early screening methods for colorectal cancer are crucial for reducing mortality rates in patients with colorectal cancer. Since microRNA(miRNA) dysregulation has been confirmed to be closely associated with colorectal cancer, high-sensitivity and accurate quantitative miRNA detection methods are regarded as effective tools for early diagnosis. In this study, we report a non-amplification-based in Situ miRNA detection strategy using localized surface plasmon resonance (LSPR) technology, where gold nanoparticles (AuNPs) immobilized on a microfluidic chip act as biosensors and ssDNA probes are employed for specific detection. Using dark-field microscopy to analyze the spectra of individual AuNPs, we achieved detection of miR-451 with a detection limit of 56 fM. This strategy amplifies the detection signal through in situ detection, avoiding the need for sample amplification. We suggest that this detection strategy can be effectively applied to miRNA detection and absolute quantification in fecal or blood samples, potentially offering a promising alternative to current miRNA detection methods. © 2025, The Authors.
