为了预测复杂孔隙结构中毛管压力主导下两相流排驱过程中的流体分布,从仿真多孔介质和岩石cT图像中抽取子样本,并采用孔隙形态模拟器(PMS)生成流体分布,以创建多样化的数据集,将距离图及像素大小、界面张力、接触角、压力作为输入参数,通过改造、训练、评估卷积神经网络(cNN)、递归神经网络(RNN)和视觉转换器(ViT),优选用于预测流体分布的模型。模拟分析表明,常用的卷积和递归神经网络在捕捉流体连通性方面存在不足。基于ViT构建了一个高维视觉转换器(HD-ViT),该转换器先忽略孔隙的空间位置仅根据其大小进行排驱,再在后处理步骤中追加流体连通要求,这种方法允许在任何坐标方向预设出入口,并使用不同尺寸和不同分辨率的图像进行渗流状态推断。通过在砂岩和碳酸盐岩大图像上验证,并与微流控驱替测试的实验结果比较,证实了HD-ViT模型的有效性、精确性和速度优势,且在捕捉孔隙尺度三维流动方面存在较大的潜力。

Open Journal of Pediatrics 2024年第3期14卷 630-644页

作者： Naiza Monono Verla Sissi Kamo helen Nguepong Vianney Nana Njamen Department of Internal Medicine and Paediatrics Faculty of Health Sciences University of Buea Buea Cameroon Regional Hospital Limbe Southwest Region Cameroon Department of Paediatrics Faculty of Medicine and Biomedical Sciences University of Garoua Garoua Cameroon Department of Obstetrics and Gynaecology Faculty of Health Sciences University of Buea Buea Cameroon

Background: Prematurity is the leading cause of neonatal mortality. Most preterm births can be associated to an identifiable risk factor. In cameroon, especially in the Southwest Region, there is limited data regarding prematurity associated risk factors. The aim of this study was to evaluate the risk factors and complications of prematurity in two health facilities in the Fako division, the BRH and RHL. Methods: A hospital based retrospective case control study was done from the 1st of January 2021 to 28th of February 2022. We assessed the gestational ages at which preterm birth occurred and their short-term outcome using a structured pretested questionnaire to collect data from files. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 26. Results: The minimum sample size was 137 preterms. 45.5% of cases were born between 34 and increased the risk of having a preterm birth meanwhile being married (AOR: 0.410;95% cI: 0.217 - 0.773;p = 0.006) decreased the risk. Hospital complications were neonatal infection 103 (51.5%), respiratory distress 79 (39.5%) and neonatal jaundice 61 (30.50%). Among the cases, 97 (48.50%) stayed in the hospital for 2 to 4 weeks and 177 (88.5%) were discharged alive. conclusions: Modifiable factors that increased the risk of prematurity were advanced maternal age, secondary level of education, rural residence, and prenatal alcohol consumption. Being married decreased the risk. The most common hospital complications in both the cases and controls were neonatal infection, respiratory distress syndrome and neonatal jaundice.
