In recent years, the integration of advanced technologies in the Intelligent Connected Vehicle (ICV) field has attracted many scholars' interests, and their safety and efficiency improved significantly. However, with the increasing number of cyber attacks and security threats in modern vehicle networks, the communication environment of vehicle is deteriorated. To solve this problem, studying the topics in zero-trust environment instead of the classic full-trust environment is becoming a effective approach. Because the traditional centralized control system is considered to be insufficient to ensure the security and reliability of ICVs, the distributed system is applied to research the ICVs. In this paper, an active disturbance rejection control (ADRC) is utilized to decrease the unknown input perturbations brought by zero-trust environment to the ICV queuing system. And it also need to ensure the stability of the vehicle formation, and to mitigate the disturbances in the dynamic driving environment. The ADRC utilizes the principles of zero-trust architecture and active disturbance rejection control to enhance the robustness and security of the queue management of ICV s. In the end, the performance of the proposed ADRC is evaluated through extensive simulations and analysis, which is to demonstrate its effectiveness and superiority in maintaining a safe and efficient vehicle queue. © 2023 IEEE.

Spatial-structural analysis of macroeconomic factors’ impact on carbon emissions in East Africa: a spatial econometric panel study

Environmental science and Pollution Research 2024年第39期31卷 51883-51901页

Despite the abundance of research on reducing carbon emissions, there is a significant gap in understanding the influence of macroeconomic factors on carbon dioxide (CO2) emissions from a spatial-structural perspective. This study aims to contribute to the literature by investigating the impact of macroeconomic factors on carbon dioxide emissions in six East African countries between 1989 and 2020. Using spatial econometric panel models, the study analyzed spatial dependence among the variables. The empirical findings indicate that gross domestic product (GDP) per capita and electricity consumption have positive direct and indirect effects on carbon emissions, while fuel prices and exports have negative direct effects, but positive spillover effects on neighboring countries. Imports have a positive impact on local economies, but negative spillover effects. Additionally, the urban population has no significant impact on the environment. These findings provide important policy implications for optimizing spatial growth patterns and achieving a low-carbon economy in East African countries. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

Spatial transcriptomics (ST) offers insights into gene expression patterns within tumor microenvironments, but its widespread application is impeded by cost constraints. To address this, predicting ST from Histology emerges as a cost-effective alternative. However, current methods such as STNet, HistoGene, and Hist2ST exhibit limitations, either overlooking stain variation across datasets or failing to well explore inter-spot correlations in scenarios with limited Whole Slide Image (WSI) data. In response, we present STFormer, a deep learning approach that incorporates the Style-Aug module to enhance feature generalization through medically-irrelevant style transfer augmentation. Additionally, the Cross-WSI Transformer module is introduced to capture Cross-WSI spot relationships efficiently. Our experimental results, conducted on both internal and external datasets, demonstrate that STFormer surpasses existing methods by a substantial margin. This showcases its potential as a powerful tool for spatial transcriptomics predictions, addressing critical gaps in current methodologies. © 2024 IEEE.

The precise prediction of preoperative recurrence in non-small cell lung cancer (NSCLC) that is suitable for clinical application is still an open question. Recent advancements integrating genomic data with deep learning have shown promise in enhancing recurrence analysis in NSCLC patients. However, the lack of interpretability in the decision-making process of DNN models has hindered their clinical trustworthiness. In this paper, we propose a novel Biologically Informed Pathway-Aware Neural Network (BioPAN). By automatically extracting biological prior knowledge to guide the architecture of DNN models, we design a unified architecture of gene-pathway-biological process-disease. This approach endows each neuron with entity meaning and learns a multi-level view of biological pathways and processes related to recurrence for fully interpretable NSCLC recurrence prediction. We demonstrated that the proposed model well explains the molecular mechanisms linking genes to NSCLC recurrence, identifies several genes that significantly promote and inhibit recurrence, and elucidates the pivotal roles of various gene pathways at the biological process level. Moreover, it outperforms classical machine learning methods, provides fully interpretable biological information, and requires fewer parameters. Broadly, BioPAN enables clinical discovery and prediction, and may have general applicability across cancer types. © 2024 IEEE.
