Background:Corticotropin-releasing hormone(CRH),the major secretagogue of the hypothalamic-pituitary-adrenal(HPA)axis,is intricately intertwined with the clock genes to regulate the circadian rhythm of various body functions.N6-methyladenosine(m^(6)A)RNA methylation is involved in the regulation of circadian rhythm,yet it remains unknown whether CRH expression and m^(6)A modification oscillate with the clock genes in chicken hypothalamus and how the circadian rhythms change under chronic ***:Chronic exposure to corticosterone(CORT)eliminated the diurnal patterns of plasma CORT and melatonin levels in the *** circadian rhythms of clock genes in hippocampus,hypothalamus and pituitary are all disturbed to different extent in CORT-treated *** most striking changes occur in hypothalamus in which the diurnal fluctuation of CRH mRNA is flattened,together with mRNA of other feeding-related ***,hypothalamic m^(6)A level oscillates in an opposite pattern to CRH mRNA,with lowestm^(6)A level after midnight(ZT18)corresponding to the peak of CRH mRNA before dawn(ZT22).CORT diminished the circadian rhythm of m^(6)A methylation with significantly increased level at *** site-specific m^(6)A analysis on 3’UTR of CRH mRNA indicates that higher m^(6)A on 3’UTR of CRH mRNA coincides with lower CRH mRNA at night(ZT18 and ZT22).Conclusions:Our results indicate that chronic stress disrupts the circadian rhythms of CRH expression in hypothalamus,leading to dysfunction of HPA axis in the *** m^(6)A modification is involved in the regulation of circadian rhythms in chicken hypothalamus under both basal and chronic stress conditions.

增强现实技术是将虚拟物体叠加到真实环境中,为了使虚拟物体更逼真地融入到环境,就需要估计场景中的真实光照。文中针对同时存在漫反射和镜面反射的场景或只存在漫反射的场景,提出了一种适于多种反射现象的光照估计方法。该方法使用相机拍摄多幅视角图像,通过检测每幅视角图像的镜面高光点来识别场景中是否存在镜面反射。若不存在镜面反射,则采用单张漫反射图像估计光照算法进行多幅视角图像光照估计。反之,若存在镜面反射则以镜面反射提供的信息为先验知识,再结合漫反射光照估计方法得到最终的光照估计结果。实验结果表明,文中方法提高了多种反射现象的光照估计的准确性。

设计一种适用于装配式钢结构的新型梁柱上焊下栓节点,腹板和下翼缘拼接板螺栓孔开成长圆孔形式以提高节点的抗震性能。为探究不同长圆孔布置方式对梁柱上焊下栓节点抗震性能的影响,通过改变腹板长圆孔的排列方式,设计了四组试件,利用ABAQUS对试件的破坏模式和拼接区的滑移情况进行了有限元分析,结果表明:带长圆孔的梁柱上焊下栓节点的梁自由端弯矩-位移角滞回曲线产生了明显的滑移现象,滑移段的出现显著提高了节点的延性,节点抗震性能优良。节点的破坏模式为拼接区悬臂梁上翼缘或下翼缘拼接板产生较为明显的屈曲变形。腹板螺栓孔布置方式的不同对节点的耗能性能影响较小,对变形破坏形态有一定影响,最后对实际工程中腹板长圆孔的布置方式给出了合理建议。

几何一致性和光照一致性在虚拟物体叠加到真实场景中的真实感渲染中起着重要作用。为了构建立体相机的真实场景和虚拟场景的坐标测量系统,实现虚实融合过程中的几何一致性和光照一致性,提升虚实融合的真实感,提出了一种几何一致性虚实融合方法,利用从三维空间到二维空间的转换,详细计算虚拟对象与真实场景之间的几何关系,并应用二维仿射变换处理二维图像,以实现更精确的计算。最后,结合光照一致性估计,使用差分渲染法将虚拟对象准确地插入到真实场景中实现虚实融合。实验结果表明,虚拟物体可以完全按照尺寸和体积融合到真实场景中,融合后的几何一致性提升了15%以上,该方法为增强现实的应用奠定了基础。
