胎儿中枢神经系统发育具有时空特异性。胎儿MRI作为一种高质量成像、无辐射、非侵入性的检查技术，不受胎儿体位、数量、胎龄、羊水量以及骨骼等影响，可对胎儿做任意方位成像，直观、定量显示胎儿中枢神经系统发育状况，并对病变进行明确诊断。借助卷积神经网络，结合残差模块和U-net完成三维卷积神经网络，可实现胎儿头部的自动提取；加入多孔空间金字塔池化网络结构，构成胎儿大脑组织分割网络；将分割出来的颅骨、脑组织、脑结构等，分别与胎儿大脑模板图像的对应部分进行线性配准，完成各组织、结构到标准空间的映射，并进行各种经线和体积的测量。未来AI将有潜力对胎儿的MR图像进行定量计算和疾病辅助诊断。

语言景观是社会语言学和语言社会学研究的交叉领域。本研究通过对国外语言景观研究经典文献和最新成果的梳理分析，评述了语言景观研究在方法论和研究领域的新拓展，如在方法论中，传统质性研究和量化研究方法基础上产生了混合研究、Q方法、统计学系列方法等，在研究领域中有边界和边境地区、中产阶级化、性别与性取向、涂鸦、超多语言标志等新话题。研究还探讨了数智时代语言景观研究的趋势和特点，最后结合中国语境的个案进行案例分析。

The price-quality tradeoff is a central question in marketing and economics. Recent advancements in modeling decision-process data have made it possible to capture individual differences in sensitivity to product quality and price. However, few studies have tested this in the field with general populations. To address this gap, we conducted a lab-in-the-field study to examine how renters balance apartment desirability against rental price. Our findings reveal that, on average, renters process apartment attributes faster than price information. Crucially, an individual-specific "price computation advantage index," derived from cursor dynamics, predicts the frequency of rent-related choices. In summary, mouse-tracking data offer a valid method for representing individual preferences in naturalistic settings.
