Two-dimensional (2D) material photodetector based on semi-floating gate (SFG) structure is expected to achieve multiple functions of information sensing, storage, and processing in a single device. Here, we demonstrated a terahertz (THz) detector based on the graphene/h-BN/graphene SFG structure. The device exhibits an excellent memory behavior and a gate-controlled non-volatile and multistate photothermoelectric (PTE) THz response. A theoretical model is established to systematically investigate the memory and PTE response characteristics, and the numerical results are well consistent with the experimental results. Our research provides valuable insights into the complex optoelectronic behavior of 2D material Semi-Floating-Gate Graphene Field-Effect Transistors (SFG-FETs) and paves the way for the realization of multifunctional photodetectors based on SFG-FET structures. © 2025 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement.

Beyond the Field-of-View: Enhancing Scene Visibility and Perception with Clip-Recurrent Transformer

IEEE Transactions on Intelligent Vehicles

IEEE Transactions on intelligent Vehicles 2024年 1-16页

作者： Shi, Hao Jiang, Qi Yang, Kailun Yin, Xiaoting Ni, Huajian Wang, Kaiwei State Key Laboratory of Extreme Photonics and Instrumentation and the National Engineering Research Center of Optical Instrumentation Zhejiang University Hangzhou China School of Robotics and the National Engineering Research Center of Robot Visual Perception and Control Technology Hunan University Changsha China Shanghai SUPREMIND Technology Company Ltd Shanghai China

Vision sensors are widely applied in vehicles, robots, and roadside infrastructure. However, due to limitations in hardware cost and system size, camera Field-of-View (FoV) is often restricted and may not provide sufficient coverage. Nevertheless, from a spatiotemporal perspective, it is possible to obtain information beyond the camera's physical FoV from past video streams. In this paper, we propose the concept of online video inpainting for autonomous vehicles to expand the field of view, thereby enhancing scene visibility, perception, and system safety. To achieve this, we introduce the FlowLens architecture, which explicitly employs optical flow and implicitly incorporates a novel clip-recurrent transformer for feature propagation. FlowLens offers two key features: 1) FlowLens includes a newly designed Clip-Recurrent Hub with 3D-Decoupled Cross Attention (DDCA) to progressively process global information accumulated over time. 2) It integrates a multi-branch Mix Fusion Feed Forward Network (MixF3N) to enhance the precise spatial flow of local features. To facilitate training and evaluation, we derive the KITTI360 dataset with various FoV mask, which covers both outer- and inner FoV expansion scenarios. We also conduct quantitative assessments of beyond-FoV semantics across different models and perform qualitative comparisons of beyond-FoV object detection. We illustrate that employing FlowLens to reconstruct unseen scenes even enhances perception within the field of view by providing reliable semantic context. Extensive experiments and user studies involving offline and online video inpainting, as well as beyond-FoV perception tasks, demonstrate that FlowLens achieves state-of-the-art performance.

Hedge-Embedded Linguistic Fuzzy Neural Networks for Systems Identification and control

IEEE Transactions on Artificial Intelligence

IEEE Transactions on Artificial Intelligence 2024年第10期5卷 4928-4937页

作者： Rafiei, Hamed Akbarzadeh-T, Mohammad-R Ferdowsi University of Mashhad Department of Electrical Engineering Center of Excellence on Soft Computing and Intelligent Information Processing Mashhad*** Iran Chalmers University of Technology Department of Electrical Engineering Center for Bionics and Pain Research Mölndal Gothenburg412 96 Sweden

In the realm of natural language processing, hedge-embedded structures have contributed considerably by appreciating linguistic variables and distinguishing overlapped classes. This aspect of natural languages considerably affects the building of linguistically interpretable architectures for fuzzy neural networks (FNNs). Here, we propose extending the idea of hedge-embedded linguistic fuzzy neural networks (LiFNNs) to the systems identification and control paradigm. This perspective leads us to the universal approximation property for this mathematical construct using the Stone–Weierstrass theorem and the proof of stability for the resulting nonlinear system identification process using the Lyapunov function. Furthermore, the power activation functions in the membership degrees of the proposed network enable linguistic hedge interpretation and more precise learning. Finally, the proposed LiFNN, optimized using a backpropagation learning algorithm, is evaluated on several problems in function approximation (periodic functions and quadratic Hermite function), system identification (a nonlinear system), and direct adaptive control fields. Results show that memberships are more distinguishable in the proposed LiFNN, leading to ∼50% less error on the average and higher granulation and interpretability. © 2020 IEEE.

Multi component gas detection in goaf can be used to determine the oxidation and spontaneous combustion status of residual coal in goaf, and to determine the development trend of spontaneous combustion of residual coal in goaf. TDLAS gas detection technology is becoming increasingly widely used due to its narrow spectral lines, which can effectively avoid cross interference. The study adopts a structure where multiple lasers share an absorption cell to construct a laser multi-component gas detection device, which greatly reduces the overall cost of the detection device, improves integration, and reduces the size of the detection device. Through the research of multi-component gas TDLAS detection technology, the structure and hardware circuit of the detection device were designed. The developed multicomponent gas detection device was used to test the detection range, detection error, and response time of six indicator gases including methane, oxygen, carbon dioxide, carbon monoxide, ethylene, and acetylene. The testing verified that the multi-component gas detection device can accurately detect each indicator gas, and the detection range, detection error, and response time meet the standard requirements. © 2024 SPIE.

Policy iteration-based adaptive optimal control for Markov jump systems: a transition-probability-free asynchronous approach

Science China(Information Sciences) 2024年第11期67卷 363-364页

The controller and filter design problems of Markov jump systems(MJSs) have gained significant attention over the past few decades. These studies include various aspects,including stochastic stabilization [1], optimal tracking control [2], and dissipative filter design [3]. Although numerous publications address the optimal controller design for MJSs, the issue of hidden MJSs, particularly those with mismatched jumping modes between the system and the controller, has rarely been explored.
