为解决新城区和城市边缘地区公交乘客等车时间长,出行便利性差,公交满载率低,公交运营者投入成本难以回收等问题,提出了考虑预约乘客等待时间的需求响应公交运营模式.此模式根据票价随预约乘客的在站等待时间增加而减少的原则进行公交票价差别定价,基于客流量变化实时更新公交车发车时刻,以缩短乘客等车时长,提高公交满载率,从而提升乘客满意度,增加公交运营者收益.构建了混合整数规划模型求解新模式下的发车时刻表和公交票价,并设计了遗传算法求解模型.之后,通过宁波市梅山新区的实际公交线路和OD量等数据进行了实例分析.通过对比计算结果和现状下的公交发车时刻,公交票价,出行者等车时长,出行成本和公交运营者收益,验证了新模式的优势.

为解决修复纹理精细、背景复杂图像中大面积不连续语义缺失时存在的边缘伪影和语义不连续的缺陷,提出一种并行生成卷积的残差连接图像修复算法。将残缺图像输入一个两列平行卷积的结构修复网络得到两个具有不同感受野大小的图像分量,通过共享解码合并两个图像分量并计算输出的L2损失优化网络。将结构修复网络的输出送入包含残差连接与注意力机制的细节修复网络,融合上下文信息,改善修复细节能力。使用全局与局部鉴别器和预训练视觉几何组网络计算损失,对修复网络进行整体判别优化,增强修复结果的整体与局部一致性。在国际公认数据库上验证提出算法的性能,实验结果表明:提出算法可以有效修复复杂背景且包含精细纹理的大面积不规则缺失区域,提升图像细节、语义和结构的真实性与完整性,其峰值信噪比和结构相似度优于经典的对比算法。

目的报道NPC1基因新发复合杂合突变致尼曼-匹克病C型一家系的临床及遗传学特点,提高临床医师对该病的认识水平。方法对云南省昆明医科大学第一附属医院神经内科2020年收治的1个非近亲结婚家系中的2例患者进行详细的神经科体格检查,提取外周血DNA,应用二代测序技术对患者进行全外显子测序,结合Sanger测序对患者家系进行一代验证,应用软件对突变位点进行分析。结果该家系呈常染色体隐性遗传,2例患者的发病年龄不同,先证者9岁起病,主要表现为:构音不良、吞咽困难、认知障碍、共济失调、双侧锥体束损害、垂直核上凝视麻痹和脾脏肿大。先证者弟弟临床表型与患者相似,但比患者更为严重,发病年龄更早,婴幼儿期发病,伴有严重的精神运动发育迟缓。全外显子组测序结果显示,两兄弟均携带NPC1基因的两种罕见变异:c.352_353del,***119ValfsTer8和c.593A>G,***198Ser。Sanger测序验证结果提示复合杂合突变分别来源于先证者的父母。根据美国医学遗传学与基因组学学会指南,上述变异评级分别为致病和疑似致病变异。该家系患者携带的c.593A>G,***198Ser变异为未报道的新变异。先证者从症状出现开始延迟诊断7年,服用麦格司他1年后吞咽困难、共济失调及眼球垂直运动障碍等症状有明显的好转。结论该家系患者的临床表型符合尼曼-匹克病C型的临床表型,NPC1基因复合杂合突变(c.352_353del和c.593A>G)为该家系的遗传学病因。
