Tackling societal challenges together: Co‐creation strategies and social innovation in EU policy and funded projects

open access: yesEuropean Policy Analysis, Volume 8, Issue 1, Page 68-86, Winter 2022., 2022
Abstract The last decade we saw an increasing academic, policy, and professional interest in the use of co‐creation to tackle societal challenges. Most research focused on qualitative analysis of case studies. This led to an understanding that co‐creation is essential for social innovation.

Nonconvex nonsmooth variational model for Poisson noise removal of gray image(基于非凸非光滑变分模型的灰度图像泊松噪声移除算法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2023
基于非凸变分方法在图像边界结构保持和对比度保持上的优势,针对泊松噪声的移除问题提出一种新的非凸非光滑正则化模型及快速求解算法。模型由非凸Lipschitz势函数复合图像梯度信息的正则化项和非线性Kullback-Leibler数据保真项两部分构成。通过使用临近点线性化策略,将求解非凸变分模型转化为求解一系列凸变分模型,进而使用交替方向乘子法求解。同时证明了算法的目标函数值序列具有单调下降性。实验结果表明,该方法能有效消除图像中的泊松噪声,且信噪比较经典算法有明显提升。

基于CT影像特征预测COVID-19患者肺部病变进展

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2023
目的基于不同阶段COVID-19患者肺部病变变化,利用CT影像学特征建立列线图模型,探讨其预测病变是否进展的效能。方法对136例新冠肺炎患者进行回顾性研究,均经2次以上CT扫描。这些患者数据被分成三个队列(训练队列,以及验证队列1和2)。训练队列中的患者根据发热症状开始至首次CT的时间分为三组,分析比较各组之间临床表现和CT特征。根据患者的CT特征构建了一个预测疾病进展的列线图,并对其性能进行了评估。结果训练队列包括41名患者。根据三个CT特征:不规则条索影、充气支气管征和不规则形态病灶的比例≥50 ...

免疫评分对低级别胶质瘤患者生存期的预测作用

open access: yesZhongguo shiyan zhenduanxue, 2022
目的 探讨低级别胶质瘤(LGG)患者中免疫评分水平的高低与总生存率(OS)的相关性,以期发现LGG的高危风险人群。方法 从TCGA数据库中获得了514名LGG患者的临床病理特征和免疫评分。Cox比例风险回归模型用于估计调整后的风险比(HR)。根据多变量分析结果,建立了列线图。模型进行了内部验证。通过时间依赖性受试者工作特征(ROC)曲线和校准曲线测量预测准确度和辨别能力。结果 根据免疫评分将患者分为3个亚组。与免疫评分较低的患者相比,免疫评分中等和较高的患者的OS的风险显著增加[HR和95%置信区间 ...
