The typhoon is one major threat to human societies and natural ecosystems, and its risk perception is crucial for contextualizing and managing disaster risks in different social settings. Social media data are a new data source for studying risk perception, because such data are timely, widely distributed, and sensitive to ***, few studies have focused on crowd sensitivity variation in social media data-based typhoon risk perception. Based on the regional disaster system theory, a framework of analysis for crowd risk perception was established to explore the feasibility of using social media data for typhoon risk perception analysis and crowd sensitivity variation. The goal was to quantitatively analyze the impact of hazard intensity and social and geographical environments on risk perception and its variation among population groups. Taking the Sina Weibo data during Typhoon Lekima of 2019 as an example, we found that:(1)Typhoon Lekima-related Weibo public attention changed in accordance with the evolution of the typhoon track and the number of Weibo posts shows a significantly positive correlation with disaster losses, while socioeconomic factors,including population, gross domestic product, and land area, are not explanatory factors of the spatial distribution of disaster-related Weibo posts;(2) Females, nonlocals with travel plans, and people living in areas with high hazard intensity, low elevation, or near waterbodies affected by Lekima paid more attention to the typhoon disaster;and(3)Descriptions of rainfall intensity by females are closer to the meteorological observation data.

有效的多模态特征融合在RGBD显著性目标检测领域中发挥着重要的作用,但如何学习到有效的多模态特征融合在目前仍然是一个挑战性的任务。不同于利用多模态显著图加权融合的传统方法,基于卷积神经网络的方法使用简单的卷积操作融合多模态特征,但这对于大量的跨模态数据融合来说是不够的。为了解决这个问题,提出了一种新颖的上采样融合模块,它不仅具有多尺度的感知能力,还同时进行全局和局部上下文推理,此外强监督残差模块增强了网络训练的稳定和有效性。与现有的方法相比,提出的方法能够提供更稳定、更灵活的融合流,从而实现了RGB和Depth信息充分、高效的融合。在三个广泛使用的RGBD显著性目标检测数据集上的大量实验证明了该方法的有效性。

试验比较了3种不同复合酶(NSP复合酶和2种NSP酶+淀粉酶)对产蛋鸡生产性能的影响。试验选取600只产蛋鸡(150日龄),随机分成4个处理,其中1组为对照组(未加酶),其它3组分别加入三种不同复合酶(复合酶D、复合酶E和复合酶F)。结果发现,日粮中添加复合酶D和复合酶E(NSP酶活性较高),蛋鸡产蛋量、产蛋率和料蛋比均显著优于对照组,而添加复合酶F(淀粉酶含量较高)蛋鸡产蛋量降低、料蛋比升高。试验组蛋鸡采食量均低于对照组,但差异不显著。添加酶制剂后消化道不同部位食糜粘度因消化道部位不同而有差异,但复合酶D和复合酶E组对不同部位食糜粘度降低程度显著大于复合酶F。以上结果表明,在典型蛋鸡玉米-杂粕型饲料中添加外源性NSP酶有助于提高蛋鸡生产性能,而NSP酶活性不足和淀粉酶过量添加可能导致产蛋鸡生产性能降低。
