金宇澄的小说《繁花》采取了图文并茂的方式来表现上海的城市空间,被认为是最好的表现上海的“城市小说”,舞台剧、电视剧《繁花》则通过舞台和影像直观地展现了上海的城市新景观。在舞台剧《繁花》中,导演马俊丰运用转台、多演区、多媒体等手段来展示舞台的假定性、空间性和意象性。电视剧《繁花》则拍出了20世纪80年代,尤其是90年代后的上海这个魔都的魅力。导演王家卫没有完全按照小说、舞台剧的散点式来结构,而是围绕着阿宝的焦点展开叙述,因此将电视剧《繁花》拍成了电影,或者说上升到了电影的高度。这也可以说是电视剧《繁花》的美学意义。

Structural health monitoring (SHM) is a multi-discipline field that involves the automatic sensing of structural loads and response by means of a large number of sensors and instruments, followed by a diagnosis of the structural health based on the collected data. Because an SHM system implemented into a structure automatically senses, evaluates, and warns about structural conditions in real time, massive data are a significant feature of SHM. The techniques related to massive data are referred to as data science and engineering, and include acquisition techniques, transition techniques, management techniques, and processing and mining algorithms for massive data. This paper provides a brief review of the state of the art of data science and engineering in SHM as investigated by these authors, and covers the compressive sampling-based data-acquisition algorithm, the anomaly data diagnosis approach using a deep learning algorithm, crack identification approaches using computer vision techniques, and condition assessment approaches for bridges using machine learning algorithms. Future trends are discussed in the conclusion.

新冠肺炎疫情持续蔓延给人类社会带来深远影响,准确预测各地区的病毒传播趋势对防控疫情而言至关重要。现有研究主要基于传统的时序预测模型和传染病模型,鲜有考虑疫情地区关联复杂和时序依赖性强的特点,限制了其疫情预测的性能。为此,针对新冠肺炎疫情的预测任务,提出了一种时空注意力驱动的自编码器框架。通过引入空间注意力机制捕捉病毒感染序列间的动态空间关联性,利用时间注意力机制挖掘病毒感染序列中复杂的时序依赖性,以此实现对不同地区的新冠肺炎病毒传播趋势的准确预测。在模型的编码器端,融合空间注意力机制的长短期记忆(LSTM)网络,关联目标地区与其他地区的病毒感染序列,提取该区域近期新冠肺炎疫情的时序特征。在模型的解码器端,将时间注意力机制引入基于LSTM网络的解码器中,通过捕捉病毒感染序列的时序依赖性推测未来的新冠肺炎疫情趋势变化。在多个公开的新冠肺炎疫情数据集上对所提模型进行验证,实验结果表明:所提模型的预测性能超越了LSTM等模型;在公开的欧洲部分国家新冠肺炎疫情数据集上,预测误差指标RMSE和MAE分别降低了22.3%和25.0%,在中国部分省级单位新冠肺炎疫情数据集上,RMSE和MAE分别降低了10.1%和10.4%。

针对当前图像风格转换算法缺乏建模图像域间语义信息和域内长范围信息的能力,提出了一种联合图像域间和域内信息建模的图像风格转换算法SSC-GAN.通过提出语义残差连接,提取图像域内的语义特征,增强模型建模图像域间语义信息差异的能力;同时,将注意力机制引入图像风格转换任务中,解决卷积缺乏图像域内长范围信息建模能力的问题.SSC-GAN可以在不增加计算量的情况下,显著提升图像风格转换的表现.在图像风格转换数据集vangh2photo和selfie2anime上对SSC-GAN进行训练、评估和验证,结果表明,SSC-GAN不仅能取得极佳的视觉效果,而且在FID和KID指标上分别平均下降了1.3和1.1,证明了SSC-GAN的有效性.
