| 2 | Northward Shift in Landfall Locations of Tropical Cyclones over the Western North Pacific during the Last Four Decades显示文摘This study analyzes landfall locations of tropical cyclones(TCs)over the western North Pacific during 1979–2018.Results demonstrate that the landfall locations of TCs over this region have shifted northward during the last four decades,primarily due to the shift of landfalling TC tracks,with the decreasing/increasing proportion of westward/northward TC tracks.In particular,the northward shift of the landfalling TCs was not related to their formation locations,which have not markedly changed,whereas'no-landed'TCs have significantly shifted northward.TC movement was significantly and positively correlated to the zonal component of the steering flow,while the correlation between TC movement and the meridional component of the steering flow was relatively unobvious.The westward steering flow in the tropical central Pacific that occurred around the formation and early development of the westward TCs was significantly weakened,which was unfavorable for their westward movement,thereby,causing the higher proportions of northward moving tracks.This weakened westward flow was related to the northward shift of the subtropical high ridge,which was caused by significant weakening of the southern part of the subtropical high.The vertical wind shear,sea surface temperature,and convective available potential energy also showed that the northern region of the western North Pacific became more favorable for TC development,whereas the upper divergence,low-layer relative vorticity,and accumulated water vapor content were not obviously related to the northward shift of TCs. | Ting CHEN Shumin CHEN Mingsen ZHOU Chaoyong TU Aoqi ZHANG Yilun CHEN Weibiao LI | 2022 | Advances in Atmospheric Sciences2022，39，2： | 3 |
| 3 | Geologic,Fluid Inclusion and Stable Isotope Constraints on Mechanisms of Ore Deposition at the Datuanshan Copper Deposit,Middle-Lower Yangtze Valley,Eastern China显示文摘The Datuanshan deposit is one of the largest and most representative stratabound copper deposits in the Tongling area,the largest ore district in the Middle-Lower Yangtze River metallogenic belt.The location of the orebodies is controlled by the interlayer-slipping faults between the Triassic and Permian strata,and all the orebodies are distributed in stratiform shape around the Mesozoic quartz monzodiorite dikes.Based on field evidence and petrographic observations,four mineralization stages in the Datuanshan deposit have been identified:the skarn,early quartz-sulfide,late quartzsulfide and carbonate stages.Chalcopytite is the main copper mineral and mainly formed at the late quartz-sulfide stage.Fluid inclusions at different stages were studied for petrography,microthermometry,laser Raman spectrometry and stable isotopes.Four types of fluid inclusions,including three-phase fluid inclusions(type 1),liquid-rich fluid inclusions(type 2),vapour-rich fluid inclusions(type 3) and pure vapour fluid inclusions(type 4),were observed.The minerals from the skarn,early and late quartz-sulfide stages contain all fluid inclusion types,but only type 2 fluid inclusions were observed at the carbonate stage.Petrographic observations suggest that most of the inclusions studied in this paper are likely primary.The coexistence of different types of fluid inclusions with contrasting homogenization characteristics(to the liquid and vapour phase,respectively) and similar homogenization temperatures(the modes are 440-480℃,380-400℃ and 280-320℃ for the skarn,early and late quartz-sulfide stages,respectively) in the first three stages,strongly suggests that three episodes of fluid boiling occurred during these stages,which is supported by the hydrogen isotope data.Laser Raman spectra identified CH_4 at the skarn and early quartz-sulfide stages.Combined with other geological features,the early ore-forming fluids were inferred to be under a relatively reduced environment.The CO_2 component has been identified at the late quartz-sulfide and carbonate stages,indicating that the late ore-forming fluids were under a relatively oxidized environment,probably as a result of inflow of and mixing with meteoric water.In addition,microthermometric results of fluid inclusions and H-O isotope data mdicate that the ore forming fluids were dominated by magmatic water in the early stages(skarn and early quartz-sulfide stages) and mixed with meteoric water in the late stages(late quartz-sulfide and carbonate stages).The evidence listed above suggests that the chalcopyrite deposition in the Datuanshan deposit probably resulted from the combination of multiepisode fluid boiling and mixing of magmatic and meteoric water. | CAO Yi DU Yangsong PANG Zhenshan DU Yilun KOU Shaolei CHEN Linjie GAO Fuping ZHOU Guibi | 2015 | Acta Geologica Sinica(English Edition)2015，89，3： | 2 |

| 7 | Fundamental Characteristics of Tropical Rain Cell Structures as Measured by TRMM PR显示文摘Rain cells are the most elementary unit of precipitation system in nature.In this study,fundamental geometric and physical characteristics of rain cells over tropical land and ocean areas are investigated by using 15-yr measurements of the Tropical Rainfall Measuring Mission(TRMM)Precipitation Radar(PR).The rain cells are identified with a minimum bounding rectangle(MBR)method.The results indicate that about 50%of rain cells occur at length of about 20 km and width of 15 km.The proportion of rain cells with length>200 km and width>100 km is less than1%.There is a a log-linear relationship between the mean length and width of rain cells.Usually,for the same horizontal geometric parameters,rain cells tend to be square horizontally and lanky vertically over land,while vertically squatty over ocean.The rainfall intensity of rain cells varies from 0.4 to 10 mm h-1 over land to 0.4–8 mm h-1 over ocean.Statistical results indicate that the occurrence frequency of rain cells decreases as the areal fraction of convective precipitation in rain cells increases,while such frequency remains almost invariant when the areal fraction of stratiform precipitation varies from 10%to 80%.The relationship between physical and geometric parameters of rain cells shows that the mean rain rate of rain cells is more frequently associated with the increase of their area,with the increasing rate over land greater than that over ocean.The results also illustrate that heavy convective rain rate prefers to occur in larger rain cells over land while heavy stratiform rain rate tends to appear in larger rain cells over ocean.For the same size of rain cells,the areal fraction and the contribution of convective precipitation are about10%–15%higher over land than over ocean. | Yunfei FU Yilun CHEN Xiangdong ZHANG Yu WANG Rui LI Qi LIU Lei ZHONG Qiong ZHANG Aoqi ZHANG | 2020 | Journal of Meteorological Research2020，34，6： | 1 |
| 8 | Image-based traffic signal control via world models显示文摘Traffic signal control is shifting from passive control to proactive control, which enables the controller to direct current traffic flow to reach its expected destinations. To this end, an effective prediction model is needed for signal controllers. What to predict, how to predict, and how to leverage the prediction for control policy optimization are critical problems for proactive traffic signal control. In this paper, we use an image that contains vehicle positions to describe intersection traffic states. Then, inspired by a model-based reinforcement learning method, DreamerV2,we introduce a novel learning-based traffic world model. The traffic world model that describes traffic dynamics in image form is used as an abstract alternative to the traffic environment to generate multi-step planning data for control policy optimization. In the execution phase, the optimized traffic controller directly outputs actions in real time based on abstract representations of traffic states, and the world model can also predict the impact of different control behaviors on future traffic conditions. Experimental results indicate that the traffic world model enables the optimized real-time control policy to outperform common baselines, and the model achieves accurate image-based prediction, showing promising applications in futuristic traffic signal control. | Xingyuan DAI Chen ZHAO Xiao WANG Yisheng LV Yilun LIN Fei-Yue WANG | 2022 | Frontiers of Information Technology & Electronic Engineering2022，23，12： | 1 |

| 13 | Targeting UHRF1-SAP30-MXD4 axis for leukemia initiating cell eradication in myeloid leukemia显示文摘Aberrant self-renewal of leukemia initiation cells(LICs)drives aggressive acute myeloid leukemia(AML).Here,we report that UHRF1,an epigenetic regulator that recruits DNMT1 to methylate DNA,is highly expressed in AML and predicts poor prognosis.UHRF1 is required for myeloid leukemogenesis by maintaining self-renewal of LICs.Mechanistically,UHRF1 directly interacts with Sin3A-associated protein 30(SAP30)through two critical amino acids,G572 and F573 in its SRA domain,to repress gene expression.Depletion of UHRF1 or SAP30 derepresses an important target gene,MXD4,which encodes a MYC antagonist,and leads to suppression of leukemogenesis.Further knockdown of MXD4 can rescue the leukemogenesis by activating the MYC pathway.Lastly,we identified a UHRF1 inhibitor,UF146,and demonstrated its significant therapeutic efficacy in the myeloid leukemia PDX model.Taken together,our study reveals the mechanisms for altered epigenetic programs in AML and provides a promising targeted therapeutic strategy against AML. | Cheng-Long Hu Bing-Yi Chen Zijuan Li Tianbiao Yang Chun-Hui Xu Ruirui Yang Peng-Cheng Yu Jingyao Zhao Ting Liu Na Liu Bin Shan Qunling Zhang Junhong Song Ming-Yue Fei Li-Juan Zong Jia-Ying Zhang Ji-Chuan Wu Shu-Bei Chen Yong Wang Binhe Chang Dan Hou Ping Liu Yilun Jiang Xiya Li Xinchi Chen Chu-Han Deng Yi-Yi Ren Roujia Wang Jiacheng Jin Kai Xue Ying Zhang Meirong Du Jun Shi Ling-Yun Wu Chun-Kang Chang Shuhong Shen Zhu Chen Sai-Juan Chen Xiaolong Liu Xiao-Jian Sun Mingyue Zheng Lan Wang | 2022 | Cell Research2022，32，12： | 1 |

| 16 | Kyanite far from equilibrium dissolution rate at 0–22℃ and pH of 3.5–7.5显示文摘Kyanite is an important and slow-dissolving mineral. Earlier work has measured its dissolution rate at high temperature and acidic pH, but experimental measurements at low temperature and near neutral p H were lacking. The rate equation by Palandri and Kharaka(A compilation of rate parameters of water–mineral interaction kinetics for application to geochemical modeling. US Geological Survey, Open File Report 2004-1068, 2004) indicates that the rate of kyanite dissolution at room temperature and near neutral pH is on the order of 10^-17 mol m^-2 s^-1, orders of magnitudes slower than most common silicate minerals such as albite and quartz. This study used an externallystirred mixed-flow reactor, which allows high solid:solution ratios, to measure the dissolution rate of kyanite at 0–22 ℃ and pH of 3.5–7.5. The measured dissolution rate of kyanite is 4.6–7.6 9 10-13 mol m^-2 s^-1 at 22℃, and the apparent activation energy is 73.5 kJ mol^-1. This dissolution rate is close to the rate of quartz dissolution and four orders of magnitude faster than the prediction by rate equation of Palandri and Kharaka(2004).Based on our new experimental data, we recommend the following rate equation for modeling the dissolution of kyanite at ambient temperatures.r=ke(-Ea)/R(1/T-1/(298.15))where k = 5.08 9 10-13 mol m^-2 s^-1, and Ea= 73.5 kJ mol^-1. Review of literature data(Carroll in The dissolution behavior of corundum, kaolinite, and andalusite: a surface complex reaction model for the dissolution of aluminosilicate minerals in diagenetic and weathering environs. Dissertation, Northwestern University, 1989) led to a recommended rate equation for andalusite as for T = 25℃ and pH = 2–10:r=k1aH+^n1+k2+k3aH^+^n3where k1= 4.04 9 10^-10 mol m^-2 s^-1, k2= 7.95×10^-10 mol m^-2 s^-1, k3= 1.01×10^-17 mol m^-2 s^-1, n1= 1.2 and n3=-0.6. | Yilun Zhang Donald J.Rimstidt Yi Huang Chen Zhu | 2019 | Acta Geochimica2019，38，4： | 1 |

| 19 | Selective capture and separation of xenon and krypton using metal organic frameworks: a review显示文摘Xenon and krypton are widespread useful noble gases in commercial lighting, lasers, electronics, and medical industry. At the same time, radioactive noble gases may proliferate from used nuclear fuel and diffuse in open atmospheres. Metal organic frameworks as hotspot porous materials for gases uptake and separation are considered to be potential solutions. In this review, we comprehensively summarized recent researches on metal organic frameworks for selective capture and separation of xenon and krypton. Particularly, we followed the aspects of different optimal design strategies, including optimal pore/cage size and geometry, open metal sites, ions (anions and cations), and polar functional groups for enhancing the xenon adsorption and separation performances. Meanwhile, a comparison of each strategy and the mechanisms of xenon/krypton separation were pointed out. The separation of krypton from gases mixtures by dual-bed systems was further discussed. Finally, some existing challenges and opportunities for possible real applications were proclaimed. | Yilun Zhou Jingyi Wang Yujie Zhao He Gu Zhongshan Chen Hui Yang Xiangke Wang | 2023 | Frontiers of Chemical Science and Engineering2023，17，12： | 0 |
