共享道路空间中的人类驾驶交互行为具有兼顾伴行车损益的社会性特征。由于对驾驶交互社会性的理解缺失,自动驾驶车辆往往难以估计自身行为对伴行车辆的潜在影响,因而陷入“被迫保守”的决策困境。本文在博弈论框架中引入驾驶人兼顾伴行车损益的行为特征,构建社会性驾驶交互行为模型,刻画了驾驶交互中个体间的动作依赖关系。结合该模型,提出主车预期行为对其交互对象所造成潜在影响的通用定量表达——交互效用项。通过在规划目标中引入交互效用项,可定向调整运动规划算法的交互主动性。高速路出匝道实验结果表明,在对安全性无显著影响的前提下,通过提升交互主动性,基于优化和基于采样的运动规划算法在给定距离内出匝道任务成功率可分别提升3.9%与5.2%。

The distinct influences of cephalosporins(CEPs, i.e., cefamandole nafate and cefpirome sulfate) affiliated to different generations on the volatile fatty acids(VFAs) production and antibiotic resistance genes(ARGs) fates during waste activated sludge(WAS) fermentation were unveiled. The presence of CEPs mainly exhibited negative effects on the total VFAs production(5%–15% reduction), especially the cefamandole nafate, which is quite different to previous understanding. Further investigation revealed that the CEPs contributed to the solubilization and hydrolysis but inhibited the acidification process by affecting the functional microbial populations(i.e., Tissierella) and general microbial metabolic activities(i.e., pyruvate metabolism and VFAs biosynthesis). In addition, CEPs(especially the cefpirome sulfate)caused the propagation of ARGs(i.e., bla TEM, tet X and mex F) during WAS fermentation. CEPs enhanced the cell membrane permeability to promote the antibiotics mechanism of efflux pump and the horizontal transfer of ARGs. Also, the CEPs altered the regulatory systems(i.e., two component system) and microbial populations associated with ARGs, resulting in the proliferation of specific ARGs. Overall, the dissimilarity of different CEPs impacts on the WAS fermentation for VFAs production and ARGs variations enlightened the diverse environmental behaviors of anthropogenic pollutants and evoked the caution of ecological risks.

目的检测肺结核患者肺部结核病灶组织中结核杆菌(Mycobacterium tuberculosis,MTB)分泌抗原ESAT-6的表达特点,为肺结核病理诊断提供依据。方法使用川北医学院附属医院病理科所储存的手术切除的肺结核组织标本作为病例标本,阴性对照为正常肺组织标本。将肺组织蜡块连续切片后,采用免疫组化(immunohistochemistry,IHC)法检测肺结核患者结核病灶组织中ESAT-6表达,并与此标本连续切片的HE染色及抗酸染色结果进行比较分析。结果ESAT-6阳性信号主要分布在结核病灶坏死区及其周围,与抗酸染色结果相比,ESAT-6抗原阳性范围与抗酸杆菌分布有关,但分布更广泛。相关分析显示,抗酸染色与IHC平均光密度(average optical density,AOD)值呈显著正相关(r=0.87,P<0.05)。结论采用IHC可以检测到肺结核病变组织中ESAT-6的表达,有可能为肺结核诊断提供依据。
