在技术和市场双轮驱动的转型背景下,后发企业如何摆脱“落后-追赶-落后”的追赶困境以实现技术和市场协同追赶值得关注。基于创新搜索、资源重构以及后发追赶相关理论,探究平行搜索对后发企业协同追赶的影响以及资源重构的中介机制,以212份调查样本进行实证分析并通过Bootstrap方法检验中介效应,揭开了平行搜索影响后发企业协同追赶的“黑箱”机制。研究表明:领先搜索与跟随搜索对后发企业协同追赶均有促进作用;领先搜索正向影响资源重组却负向影响资源重置,而跟随搜索对资源重组和资源重置的影响与之相反;资源重组和资源重置均对协同追赶有促进作用,二者在领先搜索和跟随搜索与协同追赶之间发挥部分中介作用。

针对传统卷积网络难以有效整合不同阶段人脸面部表情的特征、存在特征表征瓶颈以及无法高效利用上下文语义等问题,提出了一种结合三维交互注意力与语义聚合的面部表情识别方法。在秩扩展(ReXNet)网络的基础上对其进行优化,在消除表征瓶颈的情况下,融合上下文特征,使其更适配表情识别任务。为捕获判别性人脸表情细粒度特征,结合非本地块与跨维度信息交互理论构建了三维交互注意力。为充分利用表情的浅中层底层特征与高层语义特征,设计了语义聚合模块,将多级全局上下文特征与高级语义信息进行聚合,达到同一类别的表情语义相互增益、增强类内一致性的目的。实验表明,该方法在公开数据集RAF-DB、FERPlus和AffectNet-8上的准确率分别为88.89%、89.53%与62.22%,展现了该方法的先进性。

In particle sizing by light extinction method, the regularization parameter plays an important role in applying regularization to find the solution to ill-posed inverse problems. We combine the generalized cross-validation （GCV） and L-curve criteria with the Twomey-NNLS algorithm in parameter optimization. Numerical simulation and experimental validation show that the resistance of the newly developed algorithms to measurement errors can be improved leading to stable inversion results for unimodal particle size distribution.

Information of droplet size and size distribution lays the basis for investigations of atomization mechanisms and performance optimization, However, the laser diffraction and phase Doppler particle analyzers have difficulty in accurately characterizing sprays with a wide range of droplet sizes and very large droplets, especially ira large number of droplets are aspherical. A method to measure size in such large- droplet sprays based on digital imaging with backward illumination was developed, including an image acquisition system and image process programs. Calibration of the measurement system was performed using a dot calibration target with different dot sizes. An experimental setup was designed and established to characterize spray nozzles under different operation loads, as well as different nozzle arrangements. Results show that the droplet size of sprays ranges from dozens of microns to several millimeters. The superiority of wide load range for such nozzles was indicated by the size-measurement results under half-load to full-load operations. The present study revealed that the image processing technique can be effectively implemented for in-line size measurements of sprays with a wide distribution of droplet size and aspherical droplets, which would be difficult to characterize bv other methods.

目的分析2010-2021年甘肃省手足口病流行特征及病原学组成,对2022-2024年甘肃省手足口病发病人数进行预测,为疾病的防控提供参考依据。方法收集2010-2021年甘肃省手足口病的发病资料,用描述性流行病学方法分析其流行特征及病原学组成。基于R语言以2010-2021年甘肃省手足口病月发病人数构建季节性自回归移动平均(ARIMA)模型,对2022-2024年甘肃省手足口病发病人数进行预测。结果 2010-2021年甘肃省共报告手足口病病例126 265例,男女报告发病率分别为0.59%、0.41%,差异存在统计学意义(χ^(2)=4 433.505,P0.05)。构建季节性ARIMA模型ARIMA(4,0,1)(2,1,1)12,预测结果显示,2022-2024年甘肃省手足口病发病水平与2021年基本一致,预测发病人数与2021年接近,并保留以往双高峰发病的特点。结论 5岁以下婴幼儿是手足口病的高发人群。其他肠道病毒逐渐变为优势毒株,夏季高发。ARIMA(4,0,1)(2,1,1)12可以拟合甘肃省手足口病发病的演变趋势并进行短期预测。
