Aims Evapotranspiration(Et)is an important component of the terrestrial water cycle and is easily affected by external disturbances,such as climate change and *** Et responses to grazing is instructive for determining grazing activity and informative for understanding the water *** this study utilized 2 years(2014 and 2017)of eddy covariance data to test how grazing regulated Et for an alpine meadow ecosystem on the tibetan Plateau(tP)by path *** Findings Radiation dominated Et with a decision coefficient of 64-74%.the soil water content(SWc)worked as the limiting factor in the fenced ***,in the grazing site,the limiting factor was the vapor pressure deficit(VPD).Grazing had large effects on Et because it greatly affected the water *** SWc and VPD were enhanced by 14.63%and 4.36%in the grazing site,***,sufficient water was supplied to Et,especially during drought,and strengthened the transpiration *** a result,a favorable micrometeorological environment was created for *** shifted the limiting factor of Et from the SWc to VPD,which weakened the limiting effect of the water conditions on Et and advanced the Et peak *** addition,grazing altered the compositions of Et by changing the community structure,which directly resulted in an increased *** summary,grazing enhanced Et through altering the community structure and micrometeorological *** findings of this study further improve our understanding of the driving mechanisms of grazing on Et and will improve our predictions for the global water cycle.

图文匹配是跨模态基础任务之一,其核心是如何准确评估图像语义与文本语义之间的相似度。现有方法是通过引入相关阈值,最大限度地区分相关和无关分布,以获得更好的语义对齐。然而,对于特征本身,其语义之间缺乏相互关联,且对于缺乏空间位置信息的图像区域与文本单词很难准确对齐,从而不可避免地限制了相关阈值的学习导致语义无法准确对齐。针对此问题,本文提出一种融合语义增强和位置编码的自适应相关性可学习注意力的图文匹配方法。首先,在初步提取特征的基础上构造图像(文本)无向全连通图,使用图注意力去聚合邻居的信息,获得语义增强的特征。然后,对图像区域的绝对位置信息编码,在具备了空间语义的图像区域与文本单词相似性的基础上获得最大程度区分的相关和无关分布,更好地学习两个分布之间的最优相关边界。最后,通过公开数据集Flickr 30 k和MSCOCO,利用Recall@K指标对比实验,验证本文方法的有效性。

目的探讨SuperPATH入路髋关节置换术治疗股骨颈骨折患者的临床疗效。方法采用回顾性病例对照研究。选取2019年1月~2023年10月在空军军医大学第一附属医院骨科行全髋关节置换术(total hip arthroplasty,THA)的股骨颈骨折患者120例,按照手术方法分为研究组(n=61例)和对照组(n=59例)。研究组采用SuperPATH入路,对照组采用后外侧入路。比较两组围术期相关指标,术后3 d、术后2周及术后1个月时的疼痛视觉模拟评分(visual analog scale,VAS)、髋关节功能Harris评分,术后1个月时的髋关节活动度,以及并发症发生率。结果围术期相关指标比较,两组手术时间、术中出血量比较均无统计学意义(P>0.05),但研究组切口长度更短,术后下床活动时间及术后住院时间均短于对照组(P0.05)。术后1个月时,研究组髋关节屈曲、外旋、内旋、外展、内收活动度明显大于对照组(P0.05)。结论SuperPATH入路髋关节置换术治疗股骨颈骨折,可改善围手术期各项指标,有效减轻术后疼痛,提高髋关节功能,改善髋关节活动度,值得临床推广应用。
