Currently, TPACK, as a teacher guidance framework, has received widespread attention from scholars both domestically and internationally. In order to elucidate the current status, focal points, and evolutionary patterns of worldwide TPACK research, the present study utilized CiteSpace visualization analysis software and HistCite software for examining the authors, institutions, countries/regions, keywords, citation clustering, and citation emergence involved in TPACK research. Findings reveal that starting from 2009, there has been a steady increase in the annual publication volume of TPACK research, with close cooperation between research institutions and countries, but weak communication among researchers. Research hotspots include pediatric content knowledge, framework, packaging, and education; Multi angle measurement of TPACK, diversified definition of "situational" factors, emphasizing teacher teaching beliefs and teacher TPACK development may become a future development trend.

This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://***/about/policies/article-withdrawal). This article has been retracted at the request of the Editor in Chief. The decision to retract this article is due to several issues that have arisen in relation to referencing and authorship on this paper. A post on PubPeer raised concerns that there are problems with a number of references on this paper – including the subject, context, relevance, validity, and veracity of references. See here for more details of the issues on Pubpeer: https://***/publications/466490A11516B66D633FBAC5AB6B36. The Editor agreed this could amount to potential citation stuffing to the benefit of certain researchers. In addition, a large number of references (35) were added after the original submission, at revision, without being highlighted to reviewers/editors. There were also serious authorship changes to the paper made during revision, without validation or authorisation. Two authors were removed at the first revision. One author was added at the paper's first revision (As'ad Alizadeh). The Corresponding Author was changed during the production stage without exceptional approval of the Editor (from Dan Wang to Tao Hai, As'ad Alizadeh and Sattam Fahad Almojil). Additionally, the name of an author was changed at the proofing stage, again, without exceptional approval of the Editor (Kamal Sharma to Aman Sharma). This breached the journal's policy on authorship. The Corresponding (and other) Authors responded to requests for clarification on the question of authorship and referencing, but those explanations did not satisfactorily address the concerns. As such and due to the nature of the irregularities uncovered, the Editor has lost confidence in the validity/integrity and findings of the article and decided to retract the article. The scientific community takes a very strong view on this matter and apologies are offered to readers. ©

A generlized Logistic model with nonlinear delayed harvest controlling is considered. The conditions for the stability and local Hopf bifurcation of the equilibrium point are obtained. Numerical examples show that our control strategy can not only control the Hopf bifurcation of the system, but also control the stability switches phenomenon. These are all very useful for the survival of the population. © 2022 IEEE.

Adaptive-triggered H ∞ sliding-mode optimal control for nonlinear input-limited systems

Communications in Nonlinear Science and Numerical Simulation 2025年

This paper concentrates on the H ∞ sliding mode optimal control (SMOC) problem for nonlinear systems with mismatched interference and constrained input. Firstly, an adaptive-triggered strategy with respect to discontinuous control part is employed which can suppress input interference and the separated matched disturbances. Also, the system trajectories are guaranteed to converge to the sliding manifold. Moreover, the adaptive-triggered strategy is optimized to self-triggered strategy with aim to avoid the real-time measurement of triggered conditions, and the minimum time interval is obtained to keep away from Zeno phenomenon. Subsequently, the optimal H ∞ control problem of sliding motion turns into a two-person ZS game issue. To derive the solutions of event-trigger HJI equation, an adaptive dynamic programming (ADP) algorithm with critic-only structure is implemented to obtain the optimal control online. Furthermore, by utilizing the Lyapunov technique, the uniformly ultimately bounded (UUB) conditions about system state and the weight estimation error are obtained. At last, simulation outcomes are analyzed to validate the effectiveness of the control strategy.

Facial expression recognition under occlusion conditions based on multi-feature cross-attention

Journal of intelligent and Fuzzy systems 2024年第4期46卷 9841-9856页

作者： Guo, Sheng Tan, Mian Cai, Shan Zhang, Zaijun Liang, Yihui Feng, Hongxi Zou, Xue Wang, Lin School of Data Science and Information Engineering Guizhou Key Laboratory of Pattern Recognition and Intelligent System Guizhou Minzu University Guiyang China School of Mathematics and Statistics Qiannan Normal University for Nationalities Key Laboratory of Complex Systems and Intelligent Optimization of Guizhou Province Duyun China Zhongshan Institute University of Electronic Science and Technology of China Zhongshan China Guizhou Aerospace Tianma Electromechanical Technology Co LTD Zunyi China

Although facial expression recognition (FER) has a wide range of applications, it may be difficult to achieve under local occlusion conditions which may result in the loss of valuable expression features. This issue has motivated the present study, as a part of which an effective multi-feature cross-attention network (MFCA-Net) is proposed. The MFCA-Net consists of a two-branch network comprising a multi-feature convolution module and a local cross-attention module. Thus, it enables decomposition of facial features into multiple sub-features by the multi-feature convolution module to reduce the impact of local occlusion on facial expression feature extraction. In the next step, the local cross-attention module distinguishes between occluded and unoccluded sub-features and focuses on the latter to facilitate FER. When the MFCA-Net performance is evaluated by applying it to three public large-scale datasets (RAF-DB, FERPlus, and AffectNet), the experimental results confirm its good robustness. Further validation is performed on a real FER dataset with local occlusion of the face. © 2024 – IOS Press.

This research presents a dynamic pre-deployment strategy based on vehicle trajectory prediction information to address the issues of coverage gaps of base stations and local traffic congestion in urban vehicle networking. Under the architecture of distributed federated learning and blockchain, numerous UAVs equipped with edge computing servers eliminate the central aggregation node and use an enhanced Raft method to train a unified Seq2Seq-GRU trajectory prediction model. In the training cycle, the scheme selects the nodes to perform parameter aggregation and model update based on the quantity of data given. Second, based on the model's prediction findings, this study offers an enhanced virtual force guide deployment method that directs the UAV to dynamically deploy across each virtual force in order to increase the vehicle's access rate and communication quality. © Published under licence by IOP Publishing Ltd.
