However, the molecular mechanism of PODNL1, a novel member of SLRP family, in glioma remains largely unknown. Therefore, this study aimed to investigate its correlation with clinical factors by glioma cohort and to identify the molecular mechanisms of aberrant PODNL1 gene expression in glioma. Our findings revealed that both PODNL1 mRNA and protein levels were markedly upregulated in glioma tissues, and high PODNL1 mRNA level was significantly associated with poor prognosis of glioma patients. In functional assays, PODNL1 knockdown significantly suppressed the proliferation and invasion abilities of glioma cells, while overexpression of PODNL1 had the opposite effect both <em>in vitro</em> and <em>in vivo</em>. Mechanistically, PODNL1 knockdown suppressed the activation of AKT/mTOR signaling and inhibited nuclear translocation of β-catenin protein in the glioma cells. Our results suggest that PODNL1 acts as an oncogenic factor in glioma by promoting glioma progression through the activation of the kinase AKT, which indeces β-catenin nuclear translocation. Additionally, PODNL1 knockdown enhanced the sensitivity of glioma cells to temozolomide, a chemotherapeutic agent commonly used in the treatment of glioma. The PODNL1/AKT/β-catenin signaling axis represents a new potential therapeutic target against glioma.

However, traditional RGB cameras exhibit a significant decline in performance when capturing nighttime traffic scenes, limiting their effectiveness in supporting ITS. In contrast, event cameras possess a high dynamic range (140 dB vs. 60 dB for traditional cameras), enabling them to overcome frame degradation in low-light conditions. Recently, multimodal learning paradigms have made substantial progress in various vision tasks, such as image-text retrieval. Motivated by this progress, we propose an adaptive selection and fusion detection method that leverages both event and RGB frame domains to optimize nighttime traffic object detection jointly. To address the challenge of unbalanced multimodal data fusion, we design a learnable adaptive selection and fusion module. This module performs feature ranking and fusion in the channel dimension, allowing efficient multimodal fusion. Additionally, we construct a novel multi-level feature pyramid network based on multimodal attention fusion. This network extracts potential features to enhance robustness in detecting nighttime traffic objects. Furthermore, we curate a dataset for nighttime traffic scenarios comprising RGB frames and corresponding event streams. Through experiments, we demonstrate that our proposed method outperforms current state-of-the-art techniques in event-based, frame-based, and event and frame fusion methods.

A backpropagation neural network model was established to analyze the effects of external factors on the dispersion of through and left-turn paths based on real trajectory data collected from 20 intersections in Shanghai, China. Twelve influencing factors in varying geometric, traffic, signalization, and traffic management conditions were considered. The predictive power and transferability of the model were verified by applying the trained model on the four new intersections. The contributions of the influencing factors on the path dispersion were explored based on the neural interpretation diagram, relative importance of influencing factors, and sensitivity analysis to offer explanatory insights for the proposed model. The results show that the mean absolute percentage errors of the path dispersion models for the through and left-turn movements are only 14.67% and 17.65%, respectively. The through path dispersion is primarily influenced by the number of exit lanes, the offset degree between the approach and exit lanes, and the traffic saturation degree on the through lane.
