摘要： IgE to galactose-alpha-1,3-galactose (alpha-gal) is linked to tick bites and an important cause of anaphylaxis and urticarial reactions to mammalian meat. The alpha-gal syndrome (AGS) is recognized as being common in the southeastern United States. However, prevalence studies are lacking and open questions remain about risk factors and clinical presentation of alpha-gal sensitization.

关键词： 深度学习   全域搜索算法   Gabor滤波器   织物疵点检测   泛化性能   图像识别  

摘要： 为解决深度学习模型在面对跨场景的织物疵点检测时存在泛化性能差的问题,在甲壳虫全域搜索算法(BAS)的基础上添加了本地搜索能力构建了一种基于甲壳虫算法的混合算法,该算法可具体分为训练阶段和检测阶段。在训练阶段,通过对无疵点织物进行训练构建二维Gabor滤波器,然后使用改进BAS的混合模型对Gabor滤波器的参数进行了优化,使改进后的算法具备全局搜索和局部搜索的能力;在检测阶段,根据在训练阶段获得最佳参数构造Gabor滤波器,对待检测的织物图像进行卷积运算,并对卷积后图像进行二值化处理,最终识别待测试织物是否含有疵点。实验结果表明:该方法的特征提取具有良好的类别区分性,更加集中在疵点范围内,检测准确率可达99.26%,具有良好的稳定性和泛化性能。

关键词： Ischemia   Stress MRI   Outcome   CAD   coronary artery disease   FT   feature tracking   GCS   global circumferential strain   LGE   late gadolinium enhancement   LVEF   left ventricle ejection fraction   MACE   major adverse cardiac event  

摘要： AbstractObjectivesWe aimed to investigate the role of feature-tracking (FT) strain in long-term risk stratification of patients with known or suspected coronary artery disease (CAD) who underwent stress cardiac MRI with dipyridamole; to determine if contrast-free stress cardiac MRI with strain measurements could provide comparable prognostic value to myocardial perfusion. Materials and methodsThis retrospective study included consecutive patients with stable symptoms suggesting possible cardiac ischemia who underwent stress cardiac MRI with dipyridamole. The mean follow-up period was 5.8 years ±1.2 [SD]. FT cardiac MRI analysis was performed for each patient to obtain 2D global peak circumferential strain (GCS). The primary outcome measure was major adverse cardiac events (MACE), defined as nonfatal myocardial infarction and cardiac death. ResultsA total of 729 patients (mean age, 63 years ±10 [SD]; 616 males) were included. MACE occurred in 70 (9.6%) patients. The presence of late gadolinium enhancement (LGE) ([HR] 2.74, [95% CI: 1.53, 4.88]; P < .001) and stress GCS (HR, 1.06 [95% CI: 1.01, 1.12]; P = .016) were independently associated with MACE. A model based on contrast-free assessment of LVEF and stress GCS showed similar performance for predicting MACE than LVEF and perfusion ( P = .056). ConclusionsIn patients with known or suspected CAD undergoing stress cardiac MRI with dipyridamole, GCS and LGE presence were independent predictors of MACE. Contrast-free stress cardiac MRI with stress GCS measurement offered prognostic value akin to myocardial perfusion assessment. Clinical relevance statementStress global circumferential strain represented an additional method to predict major adverse cardiac events in patients undergoing stress cardiac MRI, even without the use of contrast agents. This would be of particular significance in patients with severe renal impairment.

摘要： 目前我国博物馆战略规划评估受制于信息壁垒,存在第三方主体与事前评估的缺环。本文基于共同价值视域,利用观点法(S-CAD评估法)评估上海博物馆“大博物馆计划”,可以发现其效应及效率较高,但存在立场偏移、执行性不足等问题。该方法通过响应多方价值立场,能够有效审视文本的内部体系,有助于为博物馆战略规划事前评估拓展思路。

关键词： 3D model   Computer aided design (CAD)   Difference identification   Engineering change management   Graph matching   Iterative mismatching elimination algorithm (IMEA)  

摘要： The identification of differences between 3D CAD models is of great significance for engineering change management. However, existing methods are unable to accurately identify the differences of CAD models under various poses. To overcome the limitation, a novel difference identification method for 3D CAD models with arbitrary locations and arbitrary orientations is proposed in this paper. Firstly, two CAD models to be compared are represented by their NURBS-based key-points, which are then matched by determining an optimal rigid transformation between the models. The parameter calculating process of the optimal rigid transformation is accelerated by a graph-based vertex pre-matching method while the calculating accuracy is guaranteed by the iterative mismatching elimination algorithm (IMEA). Finally, the differences between CAD models are identified hierarchically based on the matching sequences of three kinds of key-points. Experimental results show that the proposed method can accurately identify the geometric differences of CAD models located at various positions and orientations. © 2024
