中华民族共同体理论体系作为马克思主义中国化时代化的最新成果,既坚持了马克思主义的基本立场、观点和方法,又立足于中华民族的历史发展和时代发展,实现了中华民族建设理论与中华民族现代国家建设理论的创新。其构建过程,就是我们党对马克思主义主动选择、不断发展并与时俱进的过程,蕴含着深刻的历史、实践、价值逻辑。从历史逻辑、实践逻辑、价值逻辑三个维度,对中华民族共同体理论体系进行多维度的探讨并结合时代背景予以考察,不仅能够明确中华民族共同体理论对于西方民族理论的批判和超越,还能够深刻阐释中华民族共同体理论对于构建人类命运共同体的现实意义。

目的研究cGAMP对小鼠脑缺血恢复期的影响及初步作用机制。方法采用线栓法制备小鼠大脑中动脉闭塞(MCAO)模型,通过行为学评分和组织病理染色观察cGAMP 对MCAO小鼠恢复期的影响。激光散斑仪器观察cGAMP对MCAO小鼠恢复期的脑血流量的影响,使用苏木精-伊红染色(HE)和尼氏染色(NISSL)观察cGAMP对MCAO小鼠大脑皮层神经元的影响,使用实时荧光定量聚合酶链反应(PCR)检测小鼠大脑皮层中肿瘤坏死因子α(TNF-α)和精氨酸酶1(Arg-1)的表达,使用蛋白免疫印迹法(Western blot)检测小鼠大脑皮层中PI3K、p-PI3K、AKT、p-AKT的表达。结果行为学观察结果显示,与模型组相比,缺血期的MCAO小鼠经 cGAMP 处理后,行为学评分降低,在提尾测试、平衡木试验和前肢抓地力牵引测试中,其运动功能均显著恢复。HE、NISSL染色中,cGAMP可减轻脑缺血恢复期小鼠神经元损伤。PCR结果表明cGAMP处理可以降低脑缺血恢复期小鼠脑组织TNF-α的表达,升高Arg-1的表达。在Western blot结果中,cGAMP处理能够显著促进PI3K、AKT的磷酸化(P<0.05)。结论 cGAMP 能明显改善脑缺血恢复期小鼠运动功能,可能是通过激活PI3K-AKT通路减轻小鼠脑缺血恢复期的神经元损伤发挥治疗作用。

In motion estimation, illumination change is always a troublesome obstacle, which often causes severely per- formance reduction of optical flow computation. The essential reason is that most of estimation methods fail to formalize a unified definition in color or gradient domain for diverse environmental changes. In this paper, we propose a new solution based on deep convolutional networks to solve the key issue. Our idea is to train deep convolutional networks to represent the complex motion features under illumination change, and further predict the final optical flow fields. To this end, we construct a training dataset of multi-exposure image pairs by performing a series of non-linear adjustments in the traditional datasets of *** estimation. Our multi-exposure flow networks （MEFNet） model consists of three main components： low-level feature network, fusion feature network, and motion estimation network. The former two components belong to the contracting part of our model in order to extract and represent the multi-exposure motion features; the third component is the expanding part of our model in order to learn and predict the high-quality optical flow. Compared with many state- of-the-art methods, our motion estimation method can eliminate the obstacle of illumination change and yield optical flow results with competitive accuracy and time efficiency. Moreover, the good performance of our model is also demonstrated in some multi-exposure video applications, like HDR （high dynamic range） composition and flicker removal.

A scenario where one ＇dumb＇ radio and multiple cognitive radios communicating simultaneously with a common receiver is considered. In this paper, we derive an achievable rate region of the multiple-user cognitive multiple-access channel （MUCMAC） under both additive white Gaussian noise （AWGN） channel and rayleigh fading channel, by using a combination of multiple user dirty paper coding （DPC） and superposition coding. Through cognition, it is assumed that the secondary users （SUs） are able to obtain the message of the primary user （PU） non-causally beforehand. Using this side information, the SUs can perform multiple user DPC to avoid the interference from the SU. Besides, the SUs can also allocate part of their transmit power to aid the PU, using superposition coding. Therefore, the capacity region of traditional multiple-access channel （MAC） can be enlarged. Moreover, some asymptotic results are shown as the number of SUs increases. In the AWGN case, it is illustrated that the maximum achievable rate of the PU grows logarithmically with the increase of the number of SUs, whereas in the Rayleigh case, we show that the cognitive gain will increase with the decreasing of the channel signal to noise ratio （SNR）.
