针对车载导航模式单一、无法根据情境差异动态改变交互策略导致用户体验不足的问题,本文提出了一种支持根据不同情境自适应车载导航交互策略的情境引擎模型。结合以用户为中心的设计流程(UCD)与情境感知理论,定义了汽车人机交互情境,并通过对典型驾驶用户进行跟车调研,提取关键情境要素,阐述了导航情境下情境引擎模型的自适应交互策略及原理,将用户对不同信息的需求程度映射至交互表现层的详细程度。进行了贴合驾驶员不同需求层级的导航HMI信息框架梳理与组件设计,对两个典型导航使用情境进行了交互界面设计与分析。结果表明,情境引擎能对各驾驶情境下的驾驶员需求进行自适应交互,可为智能座舱驾驶交互体验的优化与研发提供借鉴。

针对民航陆空通话领域语料难以获取、实体分布不均,以及意图信息提取中实体规范不足且准确率有待提升等问题,为了更好地提取陆空通话意图信息,提出一种融合本体的基于双向转换编码器(bidirectional encoder representations from transformers,BERT)与生成对抗网络(generative adversarial network,GAN)的陆空通话意图信息挖掘方法,并引入航班池信息对提取的部分信息进行校验修正,形成空中交通管制(air traffic control,ATC)系统可理解的结构化信息。首先,使用改进的GAN模型进行陆空通话智能文本生成,可有效进行数据增强,平衡各类实体信息分布并扩充数据集;然后,根据欧洲单一天空空中交通管理项目定义的本体规则进行意图的分类与标注;之后,通过BERT预训练模型生成字向量并解决一词多义问题,利用双向长短时记忆(bidirectional long short-term memory,BiLSTM)网络双向编码提取上下句语义特征,同时将该语义特征送入条件随机场(conditional random field,CRF)模型进行推理预测,学习标签的依赖关系并加以约束,以获取全局最优结果;最后,根据编辑距离(edit distance,ed)算法进行意图信息合理性校验与修正。对比实验结果表明,所提方法的宏平均F_(1)值达到了98.75%,在民航陆空通话数据集上的意图挖掘性能优于其他主流模型,为其加入数字化进程奠定了基础。

青海湖官方祭祀是特殊的文化事象,它根植于中华土壤,并从四海祭祀中分离出来成为官方重要的祭祀活动。明清期间,经国家的社会治理后青海湖的神圣性得以确立并开始近祭会盟;民国时期,青海湖官方祭祀不断革新,使其成为环湖地区的特色文化事象。梳理该文化事象历史,认为青海湖官方祭祀虽然是统治者维系统治权的工具,但在促进国家统一、边疆稳定、地方文化发展上发挥了重要作用;是国家意志建构地方文化中的典型;对我们当下如何建设共建、共享的精神文化空间有积极意义。

目的观察膜转运体Megalin、Cubilin在发生发育小鼠肾内的分布,从而揭示它们在肾发生发育中相应功能分化的时空规律。方法C57BL/6小鼠按雌雄1∶1合笼饲养,并于胚(胎)龄(ed)E10、12、14、16、18 d,及生后日龄(Pd)P1、3、7、14、28、42 d,分离胎鼠、仔鼠或成鼠的肾脏。应用改良的块染技术对不同发育阶段的肾脏组织进行整体固定及染色,分别进行常规石蜡包埋,制成连续的石蜡切片(5μm)。选取连续切片中目标切片,采用免疫组织化学技术和免疫荧光技术对不同发育阶段的小鼠肾脏膜转运体Megalin和Cubilin进行定位,观察其在不同发育阶段的表达情况。结果Megalin和Cubilin在E10 d的中肾管上皮细胞开始有表达,E12 d时表达于肾脏输尿管芽上皮细胞的近腔面游离缘,二者主要以共表达模式存在。E14 d以后在发生发育小鼠肾脏的“逗号”小体、“S”型小体上皮细胞的游离缘呈弱表达,于肾脏近端小管的上皮细胞游离缘表达明显,偶尔可见在未发育成熟的血管球有弱表达。Megalin和Cubilin在细段、远端小管、集合管系统以及间质部分都未见表达。结论膜转运体Megalin和Cubilin在中肾管、输尿管芽、“逗号”小体、“S”型小体,以及近端小管的依次表达规律提示小鼠肾脏在中肾形成时期就开始有蛋白或多肽的转运功能。此外,二者稳定地出现在较为成熟的近端小管,较弱地出现在未成熟近端小管,表明其重吸收蛋白质的功能与近端小管结构的成熟度有关。
