社区生活圈是城市空间中居民日常活动的主要场所，通过生活圈规划引导居民绿色出行是建设低碳城市的重要途径。科学评估生活圈规划的减碳潜力、明确测算各类规划要素的减碳幅度，对于实现规划引导的低碳城市建设目标具有重要的现实意义。结合上海市15分钟社区生活圈规划背景，构建一套生活圈规划减碳潜力的评估方法，并以北新泾街道为例进行实际评估。研究发现，生活圈规划对居民绿色出行将产生良好的引导效果，规划实施后能够分别降低街道全年居民出行和全年周末出行碳排放总量的18.7%和5.6%。同时，识别出一系列具有显著减碳潜力的规划指标。基于这一评估方法，未来还可以进一步将评估范围从社区尺度扩展至城市、都市圈等不同尺度，为制定相关的规划减碳策略提供科学的参考依据。

A new model developed from the full-spectrum model of Lyzenga and Bennett （ 1988 ） is built up by us preliminarily through considering the impact of the ocean surface mixed layer turbulence on SAR remote sensing of internal solitary waves. In the partial differential equation of the action spectral density of the surface gravity-capillary waves the source function representing the contribution of the turbulence is added besides the usual source function representing the contribution of the wind. The source function is determined by applying the κ - ε model and adopting the Nasmyth spectrum of oceanic turbulence （ Nasmyth, 1970; Oakey, 1982; Fan, 2002） on the basis of the previous simulation results of internal tide transformation obtained in the companion paper （Fan et al. ,2008）. Either under relatively high wind speed, or under low wind speed, our model predicts significant large modulations of radar backscatter at all three bands （ L, C and X bands） for both VV and HH polarization. These results prove that considering the impact of ocean surface mixed layer turbulence on SAR remote sensing of internal solitary waves is reasonable and appropriate for settlement of the well-known problem of contemporary radar imaging models.

The condensate and bunker oil leaked from the Sanchi collision would cause a persistent impact on marine ecosystems in the surrounding areas. The long-term prediction for the distribution of the oil-polluted water and the information for the most affected regions would provide valuable information for the oceanic environment protection and pollution assessment. Based on the operational forecast system developed by the First Institute of Oceanography, State Oceanic Administration, we precisely predicted the drifting path of the oil tanker Sanchi after its collision. Trajectories of virtual oil particles show that the oil leaked from the Sanchi after it sank is mainly transported to the northeastern part of the sink location, and quickly goes to the open ocean along with the Kuroshio. Risk probability analysis based on the outcomes from the operational forecast system for years 2009 to2017 shows that the most affected area is at the northeast of the sink location.

目的探讨AURKB mRNA在黑素瘤组织中的表达及其与临床—病理特征及预后的关系。方法下载TCGA数据库中皮肤黑素瘤的数据集,采用COX回归分析皮肤黑素瘤患者不良预后的危险因素,AURKB mRNA表达水平与中位生存时间的关系采用GEPIA在线数据库分析,TIMER数据库分析皮肤黑素瘤组织中AURKB mRNA表达与免疫细胞浸润程度的相关性;皮肤黑素瘤中与AURB的共表达基因采用ULCAN数据库筛选,对共表达基因进行GO和KEGG富集分析。选择2例黑素瘤患者的肿瘤组织及癌旁组织,Western blot法验证AURKB在黑素瘤组织及癌旁组织中表达水平的差异。结果COX回归分析结果显示,病理学N分期(N2&N3)、Breslow深度(>3 mm)和AURKB mRNA(高表达)是皮肤黑素瘤患者发生不良预后的独立危险因素。皮肤黑素瘤组织中AURKB mRNA高表达228例,低表达229例,AURKB mRNA低表达组中位生存时间为102.82个月,高表达组中位生存时间为61.34个月,两组中位生存时间存在显著差异(HR=1.38,P=0.018)。在皮肤黑素瘤中,AURKB mRNA与Th2细胞(r=0.376,P<0.001)具有显著正相关性,与Th17细胞(r=-0.223,P<0.001)、NK细胞(r=-0.166,P<0.001)等具有显著负相关性。在皮肤黑素瘤中,与AURKB显著正相关和负相关的基因分别为646个和21个,选取100个显著正相关和21个显著负相关的基因进行富集分析,CC包括核浆、着丝粒、胞质等,MF包括蛋白质结合、微管结合等;BP包括细胞分裂等;KEGG包括细胞周期、DNA复制等。黑素瘤癌组织和癌旁组织中AURKB的相对灰度值分别为(1.332±0.214)和(0.321±0.021),与癌旁组织相比,AURKB表达水平在黑素瘤组织中显著升高(t=45.232,P<0.001)。结论AURKB在黑素瘤组织中表达水平显著升高,AURKB高表达与患者的不良预后有关,AURKB可能通过调控细胞周期等参与黑素瘤的恶性进展。

Avian metapneumovirus(aMPV) is a highly contagious pathogen that causes acute upper respiratory tract diseases in chickens and turkeys, resulting in serious economic losses. Subtype B aMPV has recently become the dominant epidemic strain in China. We developed an attenuated aMPV subtype B strain by serial passaging in Vero cells and evaluated its safety and efficacy as a vaccine candidate. The safety test showed that after the 30th passage, the LN16-A strain was fully attenuated, as clinical signs of infection and histological lesions were absent after *** LN16-A strain did not revert to a virulent strain after five serial passages in chickens. The genomic sequence of LN16-A differed from that of the parent wild-type LN16(wtLN16) strain and had nine amino acid mutations. In chickens, a single immunization with LN16-A induced robust humoral and cellular immune responses, including the abundant production of neutralizing antibodies, CD4^(+) T lymphocytes, and the Th1(IFN-γ) and Th2(IL-4 and IL-6)cytokines. We also confirmed that LN16-A provided 100% protection against subtype B aMPV and significantly reduced viral shedding and turbinate inflammation. Our findings suggest that the LN16-A strain is a promising live attenuated vaccine candidate that can prevent infection with subtype B aMPV.
