Soil salinization severely impacts crop yields, threatening global food security. Understanding the salt stress response of Brassica napus (B. napus), a vital oilseed crop, is crucial for developing salt-tolerant varieties. This study aims to comprehensively characterize the dynamic transcriptomic response of B. napus seedlings to salt stress, identifying key genes and pathways involved in this process. RNA-sequencing on 43 B. napus seedling samples are performed, including 24 controls and 19 salt-stressed plants, at time points of 0, 1, 3, 6, and 12 h. Differential expression analysis using 33 control experiments (CEs) identified 39,330 differentially expressed genes (DEGs). Principal component analysis (PCA) and a novel penalized logistic regression with k-Shape clustering (PLRKSC) method identify 346 crucial DEGs. GO enrichment, differential co-expression network analysis, and functional validation through B. napus transformation verify the functional roles of the identified DEGs. The analysis reveals highly dynamic and tissue-specific expression patterns of DEGs under salt stress. The identified 346 crucial DEGs include those involved in leaf and root development, stress-responsive transcription factors, and genes associated with the salt overly sensitive (SOS) pathway. Specifically, Overexpression of RD26 (BnaC07g40860D) in B. napus significantly enhances salt tolerance, confirming its role in salt stress response. This study provides a comprehensive understanding of the B. napus salt stress response at the transcriptomic level and identifies key candidate genes, such as RD26, for developing salt-tolerant varieties. The methodologies established can be applied to other omics studies of plant stress responses.

In recent years, Convolutional Neural Networks (CNNs) have become a cornerstone in computer vision tasks, but ensuring stable training remains a challenge, especially when high learning rates or large datasets are involved, as standard optimization techniques like Stochastic Gradient Descent (SGD) can suffer from oscillations and slow convergence. In this paper, we leverage control theory to propose a novel stability-driven training method by modeling the CNN training process as a dynamic control system where we introduce Lyapunov Stability analysis, implemented with Quadratic Lyapunov Function, to guide real-time learning rate adjustments, ensuring stability and faster convergence. We provide both theoretical insights and practical guidelines for the implementation of the learning rate adaptation. We examine the effectiveness of this approach in mitigating oscillations and improving training performance by comparing the proposed Lyanpunov-stability-enhanced SGD, termed SGD-DLR (SGD with Lyapunov-based Dynamic Learning Rate), to traditional SGD with a fixed learning rate. We also conduct experiments on the datasets CIFAR-10 and CIFAR-100 to demonstrate that SGD-DLR enhances both stability and performance, outperforming standard SGD. The code used for the experiment has been released on GitHub: https://***/DahaoTang/ADC-2024-SGD DLR.

High-precision digital twin model construction and real-time data fusion technology are the core of digital twin technology, which jointly support the whole life cycle simulation, verification, prediction and control of physical entities. In this paper, the construction process of high-precision digital twin model is deeply discussed, including four stages: data acquisition and processing, preliminary model establishment, model refinement and optimization, simulation verification and iterative update. In terms of key technologies and algorithms, this paper analyzes 3D modeling and geometric processing technology, physical properties and behavior simulation technology, and data fusion and real-time update technology. In particular, this paper discusses the role of data fusion algorithms such as Kalman filter in improving the accuracy and reliability of data. In the part of real-time data fusion technology, this paper discusses the data source and diversity, the fusion method and process, and the strategy of using clustering algorithm and machine learning model to improve the efficiency of data fusion. In the face of challenges, this paper points out some problems, such as data security and privacy protection, insufficient generalization ability of models, difficulties in data acquisition and integration, bottlenecks in real-time performance and lack of industry standards, and puts forward corresponding improvement measures. Finally, this paper looks forward to the future development of digital twin technology, and emphasizes the importance of data-driven intelligent modeling methods, cross-industry standardization and innovative applications in intelligent manufacturing, smart cities, smart medical care and other fields.
