In the era of artificial intelligence generated content (AIGC), conditional multimodal synthesis technologies (e.g., text-to-image) are dynamically reshaping the natural content. Brain signals, serving as potential reflections of how the brain interprets external information, exhibit a distinctive one-to-many correspondence with various external modalities. This correspondence makes brain signals emerge as a promising guiding condition for multimodal synthesis (e.g., image, text, and audio), which is crucial for developing practical brain–computer interface systems and unraveling complex mechanisms underlying human perception. This survey comprehensively examines the emerging field of brain-conditional multimodal synthesis, termed AIGC-brain, to delineate the current landscape and future directions. To begin, related neuroimaging datasets and generative models are introduced as the foundation of AIGC-brain decoding and analysis. Next, we present a comprehensive taxonomy according to AIGC-brain methodologies, followed by task-specific representative work and implementation details to facilitate in-depth comparison and analysis. Quality assessments are then introduced for both qualitative and quantitative evaluation. Finally, this survey explores insights gained, outlining current challenges and prospects of AIGC-brain. As a pioneering survey, this article paves the way for future advances in AIGC-brain research. © 2020 IEEE.

Electroencephalogram (EEG) signals are crucial in understanding brain activity, particularly in assessing attention levels, and are vital for various cognitive functions and daily activities. This study presents the design of an attention-level prediction system utilizing EEG signal analysis, employing Long Short-Term Memory (LSTM) networks enhanced by Particle Swarm Optimization (PSO). The system collects EEG data through non-invasive single-channel devices and processes these signals to predict attention levels using an LSTM model. To address the challenge of optimal parameter selection in LSTM, the PSO algorithm is integrated, significantly improving prediction accuracy. Experimental results demonstrate that the PSO_LSTM model outperforms traditional LSTM networks in terms of accuracy, convergence speed, and robustness. The proposed system not only enhances the predictive performance of attention levels but also provides a scalable approach for real-time applications in fields such as education, healthcare, and human-computer interaction. This study highlights the potential of combining EEG signal analysis with advanced machine learning techniques for more effective attention monitoring. © 2024 IEEE.

Wavefront reconstruction is a powerful technique for accurately restoring all information about an object, with holography being the most effective method for achieving this. In this paper, we propose a reflective holographic wavefront recording optical system that expands the space-bandwidth product (SBP) using spatial multiplexing technology. This approach enables the recording capacity of holograms that far exceed the display capacity of a spatial light modulator (SLM), and facilitates high-resolution wavefront reconstruction of virtual objects. Using computer-generated hologram algorithms, the wavefront encoding of virtual objects is achieved, and high- resolution holograms are recorded. The holographic reconstruction image displayed on the SLM is passed through a 4f system and used to extract the wavefront information of the object. Experimental results show that under reconstruction light illumination, the holographic plate successfully reconstructs the wavefront and displays the virtual object. The SBP of the reconstructed image significantly exceeds that of a single SLM. © 2024 IEEE.

A sperm manipulation and selection platform using optoelectronic tweezers is proposed in this paper, fully leveraging the high throughput, damage-free, and contactless advantages of optoelectronic tweezers, combined with advanced computer vision techniques, to achieve precise manipulation and selection of sperm. Initially, through simulation, the force conditions of sperm under the optoelectronic tweezers are studied, followed by the development of a sperm detection algorithm based on YOLOv8, ByteTrack, and average speed strategies. This leads to the successful construction of a sperm manipulation and selection system encompassing detection, tracking, speed measurement, and manipulation. Experimental results demonstrate that the system can achieve high-precision manipulation of individual sperm, rapidly and orderly ar-range multiple sperms, and effectively select sperm based on morphology, speed, and vitality. Additionally, the system can significantly increase sperm concentration in a short period and effectively transport groups of sperm. With the increasing problem of infertility, particularly the decline in male sperm quality, this research provides an effective technical means for the development of efficient sperm manipulation and selection technology. © 2024 IEEE.

Dear Editor,This letter concerns the development of approximately bi-similar symbolic models for a discrete-time interconnected switched system(DT-ISS).The DT-ISS under consideration is formed by connecting multiple switched systems known as component switched systems(CSSs).Although the problem of constructing approximately bi-similar symbolic models for DT-ISS has been addressed in some literature,the previous works have relied on the assumption that all the subsystems of CSSs are incrementally input-state stable.
