    Abstract With the rapid growth of car ownership today, choosing self-driving travel has become the first choice for many people. At the same time, we should pay attention to the safety issues in the process of self-driving travel. The “road rage” emotions of self-driving drivers during the driving process pose a threat to the safety of the individual driver and the passengers in the car. Based on the traffic-oriented intelligent terminal and system platform, this article explores ways to reduce the emotion of “road rage” from the perspective of management and control. The methods discussed in this article can also help reduce environmental pollution and ensure travel safety.

    Abstract High-speed detection of abnormal frames in surveillance videos is essential for security. This paper proposes a new video anomaly-detection model, namely, feature trajectory-smoothed long short-term memory (FTS-LSTM). This model trains an LSTM autoencoder network to generate future frames on normal video streams, and uses the FTS detector and generation error (GE) detector to detect anomalies on testing video streams. FTS loss is a new indicator in the anomaly-detection area. In the training stage, the model applies a feature trajectory smoothness (FTS) loss to constrain the LSTM layer. This loss enables the LSTM layer to learn the temporal regularity of video streams more precisely. In the detection stage, the model utilizes the FTS loss and the GE loss as two detectors to detect anomalies. By cascading the FTS detector and the GE detector to detect anomalies, the model achieves a high speed and competitive anomaly-detection performance on multiple datasets.

    Abstract With the development of 3D sensors technology, 3D point cloud is widely used in industrial scenes due to their high accuracy, which promotes the development of point cloud compression technology. Learned point cloud compression has attracted much attention for its excellent rate distortion performance. However, there is a one-to-one correspondence between the model and the compression rate in these methods. To achieve compression at different rates, a large number of models need to be trained, which increases the training time and storage space. To address this problem, a variable rate point cloud compression method is proposed, which enables the adjustment of the compression rate by the hyperparameter in a single model. To address the narrow rate range problem that occurs when the traditional rate distortion loss is jointly optimized for variable rate models, a rate expansion method based on contrastive learning is proposed to expands the bit rate range of the model. To improve the visualization effect of the reconstructed point cloud, a boundary learning method is introduced to improve the classification ability of the boundary points through boundary optimization and enhance the overall model performance. The experimental results show that the proposed method achieves variable rate compression with a large bit rate range while ensuring the model performance. The proposed method outperforms G-PCC, achieving more than 70% BD-Rate against G-PCC, and performs about, as well as the learned methods at high bit rates.

    Abstract This study aimed to investigate the structure, fatty acids and protein release and antioxidant activities of sesame paste (SP) formulated with flaxseed during in vitro gastrointestinal digestion and compared with SP and flaxseed paste (FP). The ratio of n‐3/n‐6 polyunsaturated fatty acid of flaxseed–sesame paste (FSP) was 0.26, which was significantly higher than that of SP (0.01). After digestion, SP contained the most abundant free linoleic acid, while the highest concentration of free linolenic acid was detected in FP. Interestingly, more soluble peptides with a molecular weight lower than 14.4 kDa were distributed in FP after gastric digestion. Meanwhile, after intestinal digestion, the hydrophilic fractions of FP showed the highest DPPH radical scavenging capacity, while the hydrophilic fractions of FP were the lowest than SP and FSP. These findings suggested that SP formulated with flaxseed as a functional ingredient could be a feasible way to increase the nutritional value of SP.

    Abstract Octupolar molecules possessing a strong two-photon response are vital for numerous advanced applications. However, accurately predicting their two-photon absorption (TPA) spectra requires high-precision quantum chemical calculations, which are computationally expensive due to repeated simulations of molecular excited-state properties. To address this challenge, we introduce a deep learning approach capable of rapidly and accurately forecasting TPA spectra for octupolar molecules. By leveraging the geometric structure as an initial descriptor, we employ a graph neural network to predict the maximum two-photon transition wavelength and cross-section. Our model demonstrates a mean absolute percentage error of less than 4% compared to time-dependent density-functional theory calculations, effectively reproducing experimental observations. Notably, this deep learning technique is nearly 100 000 times faster than comparable quantum calculations, making it an efficient and cost-effective tool for simulating TPA properties of octupolar molecules. Furthermore, this method holds great promise for the high-throughput screening of exceptional TPA materials.

    Abstract Purpose: To investigate the clinical application value of the non-shared incentive diffusion imaging technique (ZOOM-DWI) diagnoses of cervical spondylotic myelopathy (CSM).
    Methods: 49 CSM patients who presented from January 2022 to December 2022 were selected as the patient group, and 50 healthy volunteers are recruited as the control group. All subjects underwent conventional MRI and ZOOM-DWI of the cervical spine and neurologic mJOA scores in patients with CSM. The spinal ADC values of segments C2-3, C4-5, C5-6, and C6-7 are measured and analyzed in all subjects, with C5-6 being the most severe level of spinal canal compression in the patient group. In addition, the study also analyzes and compares the relationship between the C5-6 ADC value and mJOA score in the patient group.
    Results: The mean ADC shows no significantly different levels in the control group. Among the ADC values at each measurement level in the patient group, except for C4-5 and C6-7 segments are not statistically significant, the remaining pair-wise comparisons all show statistically significant differences (F = 24.368, p < 0.001). And these individuals have the highest ADC value at C5-6. The C5-6 ADC value in the patient group is significantly higher compared with the ADC value in the control group (t = 9.414, p < 0.001), with statistical significance. The ADC value at the patient stenosis shows a significant negative correlation with the mJOA score (r = -0.493, p < 0.001).
    Conclusion: Cervical ZOOM-DWI can be applied to diagnose CSM, and spinal ADC value can use as reliable imaging data for diagnosing cervical myelopathy.

    Abstract Interest in oleogel as a promising alternative to traditional hydrogenated vegetable oil has increasingly grown in recent years due to its low content of saturated fatty acids and zero trans fatty acids. This study aimed to develop wax-based margarine to replace traditional commercial margarine. The wax-based margarine was prepared and compared with commercial margarine in texture, rheology, and microscopic morphology. The possibility of preparing margarine at room temperature (non-quenched) was also explored. The results showed that the hardness of oleogel-based margarine increased as the BW concentration increased. Denser droplets and crystal network structure were observed with the increase in BW content. XRD patterns of oleogel-based margarine with different content BW were quite similar and structurally to the β' form. However, the melting temperature of oleogel-based margarine was over 40 °C at each concentration, which represented a poor mouth-melting characteristic. In addition, the unique, improved physical properties of oleogel-based margarine were obtained with binary mixtures of China lacquer wax (ZLW) and Beeswax (BW), due to the interaction of the ZLW and BW crystal network. The rapid cooling process improved the spreadability of oleogel-based margarine. The margarine prepared by 5% BW50:ZLW50 had similar properties to commercial margarine in texture and melting characteristics (37 °C), which had the potential to replace commercial margarine.

    Abstract As one of the methods of high-resolution 3D reconstruction, generating dense 3D point clouds from a single image has always been of high interest in the field of computer vision. In view of most methods focusing on the single feature information of the target and the large amount of sample data used, the method of a multi-stage reconstruction of dense point cloud network based on feature diversity is proposed, which is composed of the first stage of the 3D reconstruction network and the second stage of the point cloud processing network. The 3D reconstruction network can reconstruct sparse point cloud from a single image based on the fusion of 2D image target shape features and 3D point cloud pose features. The second-stage point cloud processing network extracts global and local features based on sparse point clouds, and increases the density of points by fusing global and local point features to obtain high-resolution dense point clouds. Deep learning fine-tuning technology is used to combine two networks to form an end-to-end network that can generate dense point clouds from a single image. The method in this paper is quantitatively and qualitatively analyzed through a large number of experiments on synthetic and real-world datasets. The results show that the average CD value of this method is 0.00698, and the EMD value is 2823.53. The result is better than some existing methods, and the point cloud reconstruction effect is better.
