2022年2月19至23日,滇中及以东地区出现强降温降雪天气,其中曲靖出现了中到大雪局部暴雪或大暴雪。利用常规观测资料、物理量场、卫星云图等数据对此次天气过程进行诊断分析。结果表明:南支槽与昆明准静止锋(冷锋)是此次强降雪天气的主要影响系统;西南气流加强、水汽通量加大以及低层水汽辐合、高层辐散为此次降雪天气过程提供了较好的水汽条件;强烈的上升运动为降雪提供了必要的动力扰动;700 hPa上-4℃等温线和地温低于0℃的温度线与雪线位置相对应;卫星云图清晰的反映了南支槽与昆明准静止锋(冷锋)的移动、交汇和发展;多普勒雷达图上也进一步证实了不断补充加强的冷空气在此次降雪过程中的重要性。此次分析从天气系统、物理量场、卫星云图和雷达回波等各个维度进行,得出了滇中及以东地区出现降雪天气的指标,对以后降雪天气的预报具有明确的指示作用。

Early and timely diagnosis of stroke is critical for effective treatment, and the electroencephalogram (EEG) offers a low-cost, non-invasive solution. However, the shortage of high-quality patient EEG data often hampers the accuracy of diagnostic classification methods based on deep learning. To address this issue, our study designed a deep data amplification model named Progressive Conditional Generative Adversarial Network with Efficient Approximating Self Attention (PCGAN-EASA), which incrementally improves the quality of generated EEG features. This network can yield full-scale, fine-grained EEG features from the low-scale, coarse ones. Specially, to overcome the limitations of traditional generative models that fail to generate features tailored to individual patient characteristics, we developed an encoder with an effective approximating self-attention mechanism. This encoder not only automatically extracts relevant features across different patients but also reduces the computational resource consumption. Furthermore, the adversarial loss and reconstruction loss functions were redesigned to better align with the training characteristics of the network and the spatial correlations among electrodes. Extensive experimental results demonstrate that PCGAN-EASA provides the highest generation quality and the lowest computational resource usage compared to several existing approaches. Additionally, it significantly improves the accuracy of subsequent stroke classification tasks. © 2024 The Authors. Published by Tech Science Press.

企业集群内部同业企业间竞争恶劣,市场价格无序竞争情势严峻,影响了集群持续发展.政府税收补贴一直以来被作为集群发展优势,但关于政府税收对企业集群发展的影响机理,尤其是关于对集群市场价格的影响作用尚不明确.基于Bertrand竞争,应用混沌控制理论,考虑政府税收,建立了群内企业分别采用Naive和GD策略的价格动态博弈混沌控制模型,研究了政府税收对市场价格动态复杂性的影响,并通过MATLAB软件进行数值仿真.研究表明:税收补贴这一集群优势对企业集群发展未必有积极作用,较低的税收比率容易导致集群市场价格的分叉和混沌;企业采用GD策略时价格调整速度大于某临界值时价格演化将会产生分叉或混沌现象;企业价格调整速度相对较大时,较高的政府税收比率有益于市场价格的演化均衡;政府税收可以改善市场价格的稳定性,增大政府税收比率可扩大价格均衡存在的稳定区域,促进市场价格的稳定性.
