In response to the challenges of high uncertainty in target threat assessment and weak coordination in situational evaluation in unmanned aerial vehicle (UAV) collaborative aerial detection, this paper designs an aerial detection collaborative threat assessment strategy based on fuzzy three support decision-making, effectively solving the problem of fuzzy information processing in aerial detection threat assessment. Firstly, a fuzzy threat model for aerial detection was established, simplifying the difficulty of the problem. Secondly, a threat degree calculation method is constructed using fuzzy multi-attribute decision-making theory, and a threat assessment classification method is constructed based on the fusion of improved prospect theory and three decision-making methods. This strengthens the evaluation algorithm’s ability to process fuzzy information on the field, making the threat assessment and evaluation system more flexible and effective. Subsequently, based on the single aircraft threat assessment results, a coordinated threat item for aerial detection situation was designed to further enhance the formation coordination attribute of unmanned aerial vehicle autonomous threat assessment. Finally, the effectiveness of the designed method was verified through digital simulation in the presence/absence of collaborative aerial detection scenarios, demonstrating its ability to resist fuzzy interference. © 2024 Copyright held by the owner/author(s).

This paper introduces a 3D soft carbon electrode array, fabricated through a one-step laser-induced process integrating a water-dissolvable polyvinyl alcohol (PVA) mask. This approach achieves precise conical microstructures and robust conductive channels using hybrid MWCNT@PDMS conductive paste. The soft carbon electrode sites with a 3D conical microstructure are designed to enhance proximity to neural tissue, thereby enhancing electrocorticogram (ECoG) signal quality and enabling effective neural stimulation. The electrode array demonstrates remarkable stretchability (25% over 1,000 cycles without failure) and stability (equivalent to 66 days in vivo). Compared to conventional materials, our electrodes exhibit superior electrochemical properties, including lower impedance (9.7 kΩ at 1 kHz) and higher signal-to-noise ratio (SNR, 61.7 dB). Thus, this one-step process is a cost-effective, scalable solution for recording and modulating central or peripheral neural tissues. © 2025 IEEE.

This paper reports a conductive Velcro electrode with micro-cracks for the first time. The laser-induced micro-cracks increase the surface area of Velcro hooks and facilitate the adhesion of more silver particles. A cluster of Nylon-Ag hook are durable with repeated mechanical compression and multiple washing. After 100 times of compression, the plastic deformation is less than 23 μm (<10%). The impedance (@10 Hz) of the Velcro electrode is still 2.6% lower than the AgCl electrode after washing for 3 times. The resilient conductive hooks can effectively penetrate through thick hair for hi-fi bioelectric signal acquisition, compared with commercial AgCl electrodes.

Materials that establish functional, stable interfaces to targeted tissues for long-term monitoring/stimulation equipped with diagnostic/therapeutic capabilities represent breakthroughs in biomedical research and clinical medicine. A fundamental challenge is the mechanical and chemical mismatch between tissues and implants that ultimately results in device failure for corrosion by biofluids and associated foreign body response. Of particular interest is in the development of bioactive materials at the level of chemistry and mechanics for high-performance, minimally invasive function, simultaneously with tissue-like compliance and in vivo biocompatibility. This review summarizes the most recent progress for these purposes, with an emphasis on material properties such as foreign body response, on integration schemes with biological tissues, and on their use as bioelectronic platforms. The article begins with an overview of emerging classes of material platforms for bio-integration with proven utility in live animal models, as high performance and stable interfaces with different form factors. Subsequent sections review various classes of flexible, soft tissue-like materials, ranging from self-healing hydrogel/elastomer to bio-adhesive composites and to bioactive materials. Additional discussions highlight examples of active bioelectronic systems that support electrophysiological mapping, stimulation, and drug delivery as treatments of related diseases, at spatiotemporal resolutions that span from the cellular level to organ-scale dimension. Envisioned applications involve advanced implants for brain, cardiac, and other organ systems, with capabilities of bioactive materials that offer stability for human subjects and live animal models. Results will inspire continuing advancements in functions and benign interfaces to biological systems, thus yielding therapy and diagnostics for human healthcare. Copyright © 2025 Xiaojun Wu et al.

This paper proposes a linear coupling group cooperative guidance law for hitting multiply fixed targets. Firstly, the models of the missile guidance and the missile communication network graph with several subgroups are established. Secondly, the cooperative group control protocol is designed for the second-order group multi-agent systems, and the group consensus is proved. Then, based on the missile guidance model and the cooperative group control protocol, a linear coupling group cooperative guidance law is proposed and its group consensus is proved. Finally, numerical simulation results show the effectiveness and the satisfactory performance of the proposed cooperative group guidance law. © 2023 Technical Committee on Control Theory, Chinese Association of Automation.

With the rapid development of science and technology, the cultivation of innovative talents become increasingly important for the future of unmanned system industry. Although a lot of research and reform have been done in recent years to improve the cultivation of unmanned system talents, there are still many problems remain unsolved. Courses and teaching models are the core of college education, through the popularization of informatization, blended learning has already become the mainstream for high-level universities. In this paper, an advanced knowledge originated online course, as well as the teaching model, are brought forward, where much of the conventional classroom lecturing would be replaced by higher-order thinking training such as analyzing, evaluating, debating, so as to stimulate the innovative consciousness. At the same time, the origination and evolution of knowledge are also carefully discussed, by which students could look back to "witness" the creation of pre-existing knowledge, and acquire the ability for knowledge update in their future innovation. © Beijing HIWING Scientific and Technological Information Institute 2024.

To address the problem of Multi-channel Interference severely affecting the signal Capture of Low-orbit Internet constellation TT & C Transponder in the Satellite Unified Spread Spectrum Measurement and Control system, this article delves into the conditions for generating Multi-channel (Cross-correlation) Interference and the impact of Multi-channel Interference on receiver capture performance from a theoretical perspective, and carries out simulation verification analysis. The simulation results show that several factors, such as Correlation characteristics of the Pseudo-random sequence, Doppler Frequency, Power of Multi-channel Interference, Modulation information data changes, the Relative Doppler frequency Difference between the Multi-channel signal and the useful signal, as well as the Coherent Integration Time Interval, determine the Strength of Multi-channel Interference. Under certain conditions, Multi-channel Interference severely affects receiver capture performance. © 2023 IEEE.
