Metaproteomic study of marine phytoplankton blooms

浮游植物是海洋初级生产力的主要贡献者，也是海洋食物链的重要组成，在海洋碳循环、生态系统维持和全球气候调节中起着重要作用。浮游植物藻华，特别是高频发生的甲藻和硅藻藻华，深刻地影响着海洋生态系统、全球气候以及人类健康。目前在浮游植物藻华形成的生态学和海洋学机制方面开展了大量工作，但我们对藻华形成的分子机制知之甚少。 本论文将宏蛋白质组学理念和方法应用于海洋浮游植物藻华研究，结合生物信息学分析手段，建立了海洋浮游植物藻华宏蛋白质组学研究方法，比较研究了藻华爆发区与非藻华区、藻华爆发期不同阶段以及现场藻华和实验室培养的浮游植物蛋白质表达谱，鉴定、确认了参与藻华形成和爆发的重要功能蛋白及其生物学过程，...Phytoplankton are the major contributors to marine primary production and also important component of marine food chain (web), they play important roles in marine carbon cycling, ecosystem maintenance and global climate regulation.

Study on the Application of PPP Model in City Water Management——A Case Analysis of PPP Model-based Water Treatment in City A

随着我国城市化的发展，城市人口大量增加，对城市水环境造成了严重影响，水源污染、水质破坏和黑臭水体等现象严重威胁人民群众的身心健康，也损害了城市的形象，制约了城市的可持续发展。加强城市水务治理，营造清洁亮丽的城市水环境，成为广大人民群众的共同愿望。但另一方面，在经济进入新常态以后，地方政府的财政收入增速下降，“稳增长、保民生”的任务给各地财政造成了巨大压力，需要寻找一种新的模式来解决城市水务治理问题。2014年起，在国务院、国家财政部、发改委等中央机关倡导下，政府与社会资本合作（PPP）模式在全国各地迅速开展，为城市水务治理带来了全新的思路，对转变政府职能，改善城市水务治理的效率和效果，满足人民...With the development of China's urbanization, the city population is dramatically increasing, causing serious impact on the city water environment. Phenomena including water pollution, water quality damage and the malodorous and black water body not only post great threat to people's physical and mental health, but also damage the image of the city, restricting the sustainable development of the c...学位：管理学硕士院系专业：管理学院_工商管理硕士(工商管理硕士)学号：1792014115099

Distribution patterns of 210Po and 210Pb and particle export in the Taiwan Strait

台湾海峡是南海和东海之间物质和能量交换的重要通道。黑潮分支、南海暖流以及大陆沿岸流等多种水系携带众多物质在此交汇并发生互相作用，形成了复杂、多变的海水环境。在几天至季节时间尺度上，海水环境可发生显著变化。因此，采用合适半衰期的放射性同位素能揭示一定时间尺度上海水环境的宏观变化。鉴于台湾海峡颗粒动力学研究很少，本论文以台湾海峡西部海域为重点研究海域，选择适合于研究季节变化的210Po-210Pb同位素指标，开展台湾海峡颗粒动力学过程的初步研究。论文对台湾海峡沿岸地区210Po、210Pb和7Be的大气沉降进行了两年的连续监测，研究了冬季（2012年2月）和夏季（2012年7月）台湾海峡西部海域2...The Taiwan Strait plays an important role in affecting the material budgets in both the East China Sea and South China Sea. Due to the interactions among the Taiwan Strait branch of Kuroshio, South China Sea Warm Current and Continental Coast Current, the biogeochemical processes in the Taiwan Strait show large variability from weekly to seasonal timescales.

Hippo signaling suppresses cell ploidy and tumorigenesis through Skp2

多倍体（polyploidy）是指细胞中含有超过两套染色体组，多倍体在生物界广泛存在，常见于高等植物、真菌、昆虫、鱼类和两栖类。虽然大多数真核生物的体细胞是二倍体，即仅含有两组染色体，分别遗传自父本和母本。但是在一些特定组织如心脏、肝脏等就含有多倍体细胞，特别是肝脏组织含有较高比例的多倍体。 多倍体细胞中心体过多复制异常分裂可以导致细胞产生异倍体、基因组不稳定性以及肿瘤的发生。前期的文献报道，多倍体细胞的形成与增殖主要是p53依赖的调控细胞周期与细胞老化｡Ｈippo通路在四倍体细胞中是激活的，因此我们进一步研究了Hippo信号通路在二倍体细胞与多倍体细胞之间的转化以及肿瘤形成中...Polyploidy is a state in which cells possess more than two sets of homologous chromosomes. Polyploidy is a widespread physiological phenomenon observed particularly in plants, fungi, insects, fishes, and amphibians. Although most of the eukaryotic somatic cells are diploid, that is, only two groups of chromosomes, inherited from the male and female, respectively.

旧城集市型社区耦合型微更新路径研究——以厦门营平片区为例

集市通常是城乡发展的发源地,而旧城集市型社区既是一个城市发展的起源,也承载着丰富的社会生活及文化记忆。目前旧城集市型社区大多面临着一系列复杂的经济及社会问题,亟需通过更新来重新激发活力,但却难以套用简单的旧城更新模式。聚焦旧城集市型社区转型的微更新路径,以厦门市营平片区为例,基于深入的调研分析,提出\"产业—人群—空间\"的耦合型微更新路径及相应的设计策略,尝试应对集市自身及集市所在社区的转型发展瓶颈,试图为我国该类型社区的转型发展提供借鉴

近25 a 银川市城市化进程中热力景观格局演变分析

Abstract： Based on the Landsat images and statistical data，in this paper the urbanization process and thermal landscape dynamics of Yinchuan City were analyzed． The objectives of this study were as follows: ① To analyze the spatial and dynamic characteristics of urban thermal landscapes based on the landscape pattern index; ② To assess the influence of the urbanization process on the thermal landscapes; ③ To understand the relationship between the land use pattern and the land surface temperature ( LST) based on the distribution index． The results showed that there was a significant heat-island effect in Yinchuan City，and the high temperature area was consistent with the built-up area and the unused land． LST declined from the downtown to the suburbs，and an obvious difference of the dynamic characters of the thermal landscapes could be identified at the different stages of urbanization． LST for various land use had obvious discrepancies，the mean LST for the land use types was in a descending order of unused land，construction land，green land and water body． Different land use types had different thermal distribution at different stages of urbanization． The land use pattern influenced the urban thermal environment，especially the spatial distribution of green land and unused land affected LST more significantly

PSO粒子群优化算法的混沌时间序列优化

经典的PSO算法以只考虑了解应当完全朝着最优的方向前进,而忽视了以前走过的路径以及搜索结果,因此,考虑使用混沌时间序列的方法,记录每个搜索节点每n步的记录,推测出最佳的第n+1步记录,然后再重新回到经典改良算法的循环。就好比鸟在觅食的时候每只鸟不是一味的只顾着搜寻食物,而是适时的停歇下来回顾自己的觅食路径反思经验。另外,给出一个改良的评价函数来指导自适应性搜索
