| 2 | When worlds collide: Th17 and Treg cells in cancer and autoimmunity显示文摘The balance between Th17 cells and regulatory T cells(Tregs)has emerged as a prominent factor in regulating autoimmunity and cancer.Th17 cells are vital for host defense against pathogens but have also been implicated in causing autoimmune disorders and cancer,though their role in carcinogenesis is less well understood.Tregs are required for self-tolerance and defense against autoimmunity and often correlate with cancer progression.This review addresses the importance of a functional homeostasis between these two subsets in health and the consequences of its disruption when these forces collide in disease.Importantly,we discuss the ability of Th17 cells to mediate cancer regression in immunotherapy,including adoptive transfer and checkpoint blockade therapy,and the therapeutic possibilities of purposefully offsetting the Th17/Treg balance to treat patients with cancer as well as those with autoimmune diseases. | Hannah M.Knochelmann Connor J.Dwyer Stefanie R.Bailey Sierra M.Amaya Dirk M.Elston Joni M.Mazza-Mc.Crann Chrystal M.Paulos | 2018 | Cellular & Molecular Immunology2018,15,5: | 50 |

| 5 | Shift to a low carbon society through energy systems design显示文摘Concern about global warming calls for an advanced approach for designing an energy system to reduce carbon emissions as well as to secure energy security for each country.Conventional energy systems tend to introduce different technologies with high conversion efficiency,leading to a higher average efficiency.Advanced energy systems can be achieved not by an aggregate form of conversion technologies but by an innovative system design itself.The concept of LCS(low carbon society) is a unique approach having multi-dimensional considerations such as social,economic and environmental dimensions.The LCS aims at an extensive restructuring of worldwide energy supply/demand network system by not only replacing the conventional parts with the new ones,but also integrating all the necessary components and designing absolutely different energy networks.As a core tool for the LCS design,energy-economic models are applied to show feasible solutions in future with alternatives such as renewable resources,combined heat and power,and smart grid operations.Models can introduce changes in energy markets,technology learning in capacity,and penetration of innovative technologies,leading to an optimum system configuration under priority settings.The paper describes recent trials of energy models application related to waste-to-energy,clean coal,transportation and rural development.Although the modelling approach is still under investigation,the output clearly shows possible options having variety of technologies and linkages between supply and demand sides.Design of the LCS means an energy systems design with the modelling approach,which gives solution for complex systems,choices among technologies,technology feasibility,R&D targets,and what we need to start. | Toshihiko NAKATA Mikhail RODIONOV Diego SILVA Joni JUPESTA | 2010 | Science China(Technological Sciences)2010,53,1: | 19 |
| 6 | 长白山林区核桃楸种群数量动态变化的研究显示文摘运用种群年龄结构、存活曲线统计和Leslie模型对长白山核桃楸种群在水胡林、针阔混交林、核桃楸占优杂木林和杂木林4种不同群落类型中种群数量动态变化进行了研究和预测。结果表明,核桃楸种群表现出衰退型的年龄结构特点,幼苗和幼树比例较小,种群在幼年期死亡率较高,反映出核桃楸种群15~20龄在个体经历了比较强烈的环境筛作用;Leslie模型预测显示,核桃楸幼苗数量和种群总数量在今后35年基本呈下降趋势,除在核桃楸占优的林分中种群维持增长外,在其它3中森林类型都表现出衰退趋势。因此,促进核桃楸的天然更新、加强幼苗幼树的抚育工作对长白山地区核桃楸种群的发展至关重要。 | 马万里 罗菊春 荆涛 Joni Kujansuu | 2008 | 植物研究2008,28,2: | 19 |
| 7 | 采伐干扰对长白山核桃楸林生物多样性的影响研究显示文摘运用Gleason丰富度指数、Simpson指数、Shannon-Wiener指数、Cody指数和重要值,对长白山核桃楸林不同采伐方式下的生物多样性及变化进行了研究。结果表明,采伐干扰下群落中草本层的植物多样性和重要值变化最大,α多样性和β多样性指数均在皆伐地表现最高,择伐地次之,未采伐地最低;在重要值上,择伐和皆伐后,草本层植物的种类组成和重要值排序明显不同于对照地。从形式上来讲是采伐方式不同引起了多样性的变化,但其实质是光照条件改变所致;从时间尺度上考虑,是时间边缘效应的结果。同时,核桃楸更新苗数量的调查表明,皆伐地内高的多样性指数和核桃楸幼苗的充分发育均是受光因子作用的结果,它们二者之间并无必然的因果关系。 | 马万里 罗菊春 荆涛 Joni Kujansuu | 2007 | 植物研究2007,27,1: | 13 |
| 8 | 长白山林区核桃楸种群分布格局研究显示文摘运用多个聚集强度指数(负二项参数K,扩散系数C,扩散型指数Iδ,Cassie指标,丛生指标I,聚块性指数m*/m)对长白山核桃楸林分布格局进行研究.结果表明,在取样大小合适的情况下,研究样地内的核桃楸幼苗、幼树及成株的分布格局均呈现聚集分布.分析认为,核桃楸具有强萌生更新能力、落果在母树周围集中和表现出在开阔地、林窗多分布的喜光特性是种群聚集分布的主要原因. | 马万里 荆涛 罗菊春 Joni Kujansuu | 2008 | 内蒙古师范大学学报(自然科学汉文版)2008,37,2: | 12 |

| 10 | Continuous and comprehensive atmospheric observations in Beijing:a station to understand the complex urban atmospheric environment显示文摘Due to profound impact on climate and human health,air quality has attracted attention from all levels of the civil society.The key step in the provision of required tools for the society to tackle the complex air quality problem is to characterize it in a comprehensive manner with a long-term perspective.Here,we describe a continuous and comprehensive observation station and its accompanying state-ofthe-art instrumentation that was established to investigate the complex urban atmospheric environment in a rapidly developing Chinese Megacity.The station,located in downtown Beijing,aims to study air quality by identifying the major atmospheric pollutants and key processes determining their formation and loss mechanisms.A few hundreds of parameters are continuously measured with the state-of-the-art instruments,including trace gas concentrations,aerosol particle size distributions,and mass concentrations,covering aerosol particle chemical composition from molecules to micrometer-sized aerosol particles.This produced long-term,comprehensive big data with around 1�10^(11)bytes per year.In this paper,we provide an overview on the facilities of the station,the instrumentation used,the workflow of continuous observations and examples of results from 2018 to 2019 and a basis for establishing a modern long-term,comprehensive atmospheric urban observation station in other megacities. | Yongchun Liu Chao Yan Zemin Feng Feixue Zheng Xiaolong Fan Yusheng Zhang Chang Li Ying Zhou Zhuohui Lin Yishou Guo Ying Zhang Li Ma Wenshuo Zhou Zhikun Liu Lubna Dada Kaspar Dallenbach Jenni Kontkanen Runlong Cai Tommy Chan Biwu Chu Wei Du Lei Yao Yonghong Wang Jing Cai Juha Kangasluoma Tom Kokkonen Joni Kujansuu Anton Rusanen Chenjuan Deng Yueyun Fu Rujing Yin Xiaoxiao Li Yiqun Lu Yiliang Liu Chaofan Lian Dongsen Yang Weigang Wang Maofa Ge Yuesi Wang Douglas R.Worsnop Heikki Junninen Hong He Veli-Matti Kerminen Jun Zheng Lin Wang Jingkun Jiang Tuukka Petaja Federico Bianchi Markku Kulmala | 2020 | Big Earth Data2020,4,3: | 3 |

| 12 | Influence of emergent macrophyte (Phragmites australis) density on water turbulence and erosion of organic-rich sediment显示文摘The effects of the emergent macrophyte Phragmites australis on water turbulence, bottom shear velocity and water turbidity were experimentally studied with the stem densities 0 stems/m 2 -100 stems/m 2 and using organic-rich sediment. It is found that the maximum root-mean-square (rms) velocity and shear velocity decrease linearly with increasing stem density. By affecting the height of peak turbulence values, emergent plants can thus lower the frequency of sediment erosion events. Additionally, the slope of the rms turbulence increment decreases with increasing stem density. Thus, also the duration of strong turbulence is affected by the density of emergent macrophytes. The critical shear velocity for sediment resuspension is 0.0035 m/s-0.0055 m/s and not affected by the stem density. In the absence of macrophytes, water flow causes a 6.3-fold increment in turbidity, but with macrophytes turbidity values remain lower. The experiments suggest that even relatively low densities of Phragmites can have substantial effects on water turbulence and consequently on water quality. | HORPPILA Jukka KAITARANTA Joni JOENSUU Laura NURMINEN Leena | 2013 | Journal of Hydrodynamics2013,25,2: | 3 |
| 13 | Seasonal comparison of moss bag technique against vertical snow samples for monitoring atmospheric pollution显示文摘This is the first study seasonally applying Sphagnum papillosum moss bags and vertical snow samples for monitoring atmospheric pollution.Moss bags,exposed in January,were collected together with snow samples by early March 2012 near the Harjavalta Industrial Park in southwest Finland.Magnetic,chemical,scanning electron microscopy-energy dispersive X-ray spectroscopy(SEM-EDX),K-means clustering,and Tomlinson pollution load index(PLI)data showed parallel spatial trends of pollution dispersal for both materials.Results strengthen previous findings that concentrate and slag handling activities were important(dust)emission sources while the impact from Cu–Ni smelter's pipe remained secondary at closer distances.Statistically significant correlations existed between the variables of snow and moss bags.As a summary,both methods work well for sampling and are efficient pollutant accumulators.Moss bags can be used also in winter conditions and they provide more homogeneous and better controlled sampling method than snow samples. | Hanna Salo Anna-Kaisa Berisha Joni M?kinen | 2016 | Journal of Environmental Sciences2016,28,3: | 3 |

| 15 | The Silk Road agenda of the Pan-Eurasian Experiment (PEEX) program显示文摘The Silk Road Economic Belt and the 21st-Century Maritime Silk Road(B&R)aims at facilitating the twenty-first Century economic development of China.However,climate change,air quality and related feedbacks are affecting the successful development of the environment and societies in the B&R geographical domain.The most urgent risks related to the atmospheric system,to the land system and to hydrospheric and cryospheric processes are changing climate-air quality interactions,air pollution,changing monsoon dynamics,land degradation,and the melting of Tibetan Plateau glaciers.A framework is needed in which a science and technology-based approach has the critical mass and expertise to identify the main steps toward solutions and is capable to implement this roadmap.The Pan-Eurasian Experiment(PEEX)program,initiated in 2012,aims to resolve science,technology and sustainability questions in the Northern Eurasian region.PEEX is now identifying its science agenda for the B&R region.One fundamental element of the PEEX research agenda is the availability of comprehensive ground-based observations together with Earth observation data.PEEX complements the recently launched international scientific program called Digital Belt and Road(DBAR).PEEX has expertise to coordinate the ground-based observations and initiate new flagship stations,while DBAR provides a big data platform on Earth observation from China and countries along the Belt and Road region.The DBAR and PEEX have joint interests and synergy expertise on monitoring on ecological environment,urbanization,cultural heritages,coastal zones,and arctic cold regions supporting the sustainable development of the Belt and Road region.In this paper we identify the research themes of the PEEX related Silk Road agenda relevant to China and give an overview of the methodological requirements and present the infrastructure requirements needed to carry out large scale research program. | Hanna K.Lappalainen Markku Kulmala Joni Kujansuu Tuukka Petaja Alexander Mahura Gerrit de Leeuw Sergej Zilitinkevich Merli Juustila Veli-Matti Kerminen Bob Bornstein Zhang Jiahua Xue Yong Qiu Yubao Liang Dong Liu Jie Guo Huadong | 2018 | Big Earth Data2018,2,1: | 2 |

| 17 | Application of a littoral Baltic Sea resuspension model in a eutrophic lake-factors behind differences in the model performance显示文摘The performance of a linear resuspension model developed in the Baltic Sea was studied in the conditions of a eutrophic Lake Kirkkoj(a|¨)rvi(southern Finland).The model predicts sediment resuspension rate using data on vegetation cover,wind and sediment quality as an input.When the original model coefficients were used,the model resulted on average 1.8 fold overestimation of the resuspension rate in Kirkkoj(a|¨)rvi.This was due to lower fetch and water depth,and less consolidated sediment of Kirkkoj(a|¨)rvi compared with the Baltic Sea study site.When coefficients were adjusted for Kirkkoj(a|¨)rvi,the model predictions were 1.1 times the measured values.Due to the continuous resuspension,the effect of the wind term in the model was so low that it could be excluded without affecting the accuracy of model predictions.The study demonstrated that in a shallow eutrophic lake accurate predictions on resuspension rate can be made using only data on sediment quality and on factors inhibiting resuspension(macrophytes).The model residuals increased with increasing resuspension rate and high rates of resuspension were underestimated by the model.Due to the fluffy sediment in Kirkkoj(a|¨)rvi,erosion of sediment increases more than linear with increasing shear stress.Thus in such conditions,even better predictions could be achieved by a non-linear resuspension model. | Jukka Horppila Joni Kaitaranta Leena Nurminen | 2015 | International Journal of Sediment Research2015,30,2: | 2 |
