1Intra-continental back-arc basin inversion and Late Carboniferous magmatism in Eastern Tianshan,NW China:Constraints from the Shaquanzi magmatic suite显示文摘The Yamansu belt,an important tectonic component of Eastern Tianshan Mountains,of the Central Asian Orogenic Belt,NW China hosts many Fe-(Cu)deposit.In this study,we present new zircon U-Pb geochronology and geochemical data of the volcanic rocks of Shaquanzi Formation and diorite intrusions in the Yamansu belt.The Shaquanzi Formation comprises mainly basalt,andesite/andesitic tuff,rhyolite and sub-volcanic diabase with local diorite intrusions.The volcanic rocks and diorites contain ca.315-305 Ma and ca.298 Ma zircons respectively.These rocks show calc-alkaline affinity with enrichment in large-ion lithophile elements(LILEs),light rare-earth elements(LREEs),and depletion in high field strength elements(HFSEs)in primitive mantle normalized multi-element diagrams,which resemble typical back-arc basin rocks.They show depleted mantle signature with ε_(Nd)(t)ranging from+3.1 to +5.6 for basalt;+2.1 to+4.7 for andesite;-0.2 to+1.5 for rhyolite and the ε_(Hf)(t)ranges from-0.1 to +13.0 for andesites;+5.8 to +10.7 for andesitic tuffs.We suggest that the Shaquanzi Formation basalt might have originated from a depleted,metasomatized lithospheric mantle source mixed with minor(3-5%)subduction-derived materials,whereas the andesite and rhyolite could be fractional crystallization products of the basaltic magma.The Shaquanzi Formation volcanic rocks could have formed in an intracontinental back-arc basin setting,probably via the southward subduction of the Kangguer Ocean beneath the Middle Tianshan Massif.The Yamansu mineralization belt might have undergone a continental arc to back-arc basin transition during the Late Carboniferous and the intra-continental back-arc basin might have closed in the Early Permian,marked by the emplacement of dioritic magma in the Shaquanzi belt.Hongjun Jiang Jinsheng Han Huayong Chen Yi Zheng Wanjian Lu Gang Deng Zhixiong Tan 2017Geoscience Frontiers2017,8,6:11

3Genome-wide Dissection of Co-selected UV-B Responsive Pathways in the UV-B Adaptation of Qingke显示文摘Qingke (Tibetan hulless barley) has long been cultivated and exposed to long-term and strong UV-B radiation on the Tibetan Plateau, which renders it an ideal species for elucidating novel UV-B responsive mechanisms in plants. Here we report a comprehensive metabolite profiling and metabolite-based genome-wide association study (mGWAS) using 196 diverse qingke and barley accessions. Our results demonstrated both constitutive and induced accumulation, and common genetic regulation, of metabolites from different branches of the phenylpropanoid pathway that are involved in UV-B protection. A total of 90 significant mGWAS loci for these metabolites were identified in barley-qingke differentiation regions, and a number of high-level metabolite trait alleles were found to be significantly enriched in qingke, suggesting co-selection of various phenylpropanoids. Upon dissecting the entire phenylpropanoid pathway, we identified some key determinants controlling natural variation of phenylpropanoid content, including three novel proteins, a flavone C-pentosyltransferase, a tyramine hydroxycinnamoyl acyltransferase, and a MYB transcription factor. Our study, furthermore, demonstrated co-selection of both constitutive and induced phenylpropanoids for UV-B protection in qingke.Xingquan Zeng Hongjun Yuan Xuekui Dong Meng Peng Xinyu Jing Qijun Xu Tang Tang Yulin Wang Sang Zha Meng Gao Congzhi Li Chujin Shu Zexiu Wei Wangmu Qimei Yuzhen Basang Jiabu Dunzhu Zeqing Li Lijun Bai Jian Shi Zhigang Zheng Sibin Yu Alisdair R.Fernie Jie Luo Tashi Nyima 2020Molecular Plant2020,13,1:9
4Organic amendments increase corn yield by enhancing soil resilience to climate change显示文摘A 22-year field experiment was conducted in Gongzhuling, Jilin province, China to investigate corn yield response to fertilization practice. Compared to an unfertilized control(CK), all fertilization treatments, including inorganic nitrogen fertilizer only(N), balanced inorganic fertilizers(NPK), NPK plus corn straw(SNPK), and NPK plus farmyard manure(MNPK), resulted in significant increases in corn yield. However, only organic matter amendments sustained increasing yield trends, with annual rates of 0.137 and 0.194 t ha-1for the SPNK and MNPK treatments, respectively(P < 0.05). During the 22 years, the daily mean, maximum and minimum temperatures increased by 0.50, 0.53, and 0.46 °C per decade, whereas precipitation displayed no significant change but showed large seasonal variation. According to a regression analysis, increased air temperature exerted positive effects on corn yields under the SNPK and the MNPK treatments. Under both treatments,soil organic carbon contents and soil nutrient availabilities increased significantly compared to their initial levels in 1990, whereas soil bulk density and total porosity changed slightly under the two treatments, which showed higher soil water storage than other treatments. In contrast, significant increases in soil bulk density and decreases in soil total porosity and soil nutrient availability were observed under the CK, N and NPK treatments. The contributions of soil fertility to corn yield were 28.4%, 37.9%, 38.4%, 39.0%,and 42.9% under CK, N, NPK, SNPK, and MNPK treatments, respectively, whereas climate changes accounted for 27.0%, 14.6%, 12.4%, 11.8%, and 10.8%. These results indicate that, in Northeast China, organic matter amendments can mitigate negative and exploit positive effects of climate change on crop production by enhancing soil quality.Zhenwei Song Hongjun Gao Ping Zhu Chang Peng Aixing Deng Chengyan Zheng Md Abdul Mannaf Md Nurul Islam Weijian Zhang 2015The Crop Journal2015,3,2:8
5A more consistent intraluminal rhesus monkey model of ischemic stroke显示文摘Endovascular surgery is advantageous in experimentally induced ischemic stroke because it causes fewer cranial traumatic lesions than invasive surgery and can closely mimic the pathophysiology in stroke patients. However, the outcomes are highly variable, which limits the accuracy of evaluations of ischemic stroke studies. In this study, eight healthy adult rhesus monkeys were randomized into two groups with four monkeys in each group: middle cerebral artery occlusion at origin segment(M1) and middle cerebral artery occlusion at M2 segment. The blood flow in the middle cerebral artery was blocked completely for 2 hours using the endovascular microcoil placement technique(1 mm × 10 cm)(undetachable), to establish a model of cerebral ischemia. The microcoil was withdrawn and the middle cerebral artery blood flow was restored. A reversible middle cerebral artery occlusion model was identified by hematoxylin-eosin staining, digital subtraction angiography, magnetic resonance angiography, magnetic resonance imaging, and neurological evaluation. The results showed that the middle cerebral artery occlusion model was successfully established in eight adult healthy rhesus monkeys, and ischemic lesions were apparent in the brain tissue of rhesus monkeys at 24 hours after occlusion. The rhesus monkeys had symptoms of neurological deficits. Compared with the M1 occlusion group, the M2 occlusion group had lower infarction volume and higher neurological scores. These experimental findings indicate that reversible middle cerebral artery occlusion can be produced with the endovascular microcoil technique in rhesus monkeys. The M2 occluded model had less infarction and less neurological impairment, which offers the potential for application in the field of brain injury research.Bo Zhao Guowei Shang Jian Chen Xiaokun Geng Xin Ye Guoxun Xu Ju Wang Jiasheng Zheng Hongjun Li Fauzia Akbary Shengli Li Jing Lu Feng Ling Xunming Ji 2014Neural Regeneration Research2014,9,23:6
6Risk assessment of malaria transmission at the border area of China and Myanmar显示文摘Background:In order to achieve the goal of malaria elimination,the Chinese government launched the National Malaria Elimination Programme in 2010.However,as a result of increasing cross-border population movements,the risk of imported malaria cases still exists at the border areas of China,resulting in a potential threat of local transmission.The focus of this paper is to assess the Plasmodium vivax incidences in Tengchong,Yunnan Province,at the border areas of China and Myanmar.Methods:Time series of P.vivax incidences in Tengchong from 2006 to 2010 are collected from the web-based China Information System for Disease Control and Prevention,which are further separated into time series of imported and local cases.First,the seasonal and trend decomposition are performed on time series of imported cases using Loess method.Then,the impact of climatic factors on the local transmission of P.vivax is assessed using both linear regression models(LRM)and generalized additive models(GAM).Specifically,the notion of vectorial capacity(VCAP)is used to estimate the transmission potential of P.vivax at different locations,which is calculated based on temperature and rainfall collected from China Meteorological Administration.Results:Comparing with Ruili County,the seasonal pattern of imported cases in Tengchong is different:Tengchong has only one peak,while Ruili has two peaks during each year.This may be due to the different cross-border behaviors of peoples in two locations.The vectorial capacity together with the imported cases and the average humidity,can well explain the local incidences of P.vivax through both LRM and GAM methods.Moreover,the maximum daily temperature is verified to be more suitable to calculate VCAP than the minimal and average temperature in Tengchong County.Conclusion:To achieve malaria elimination in China,the assessment results in this paper will provide further guidance in active surveillance and control of malaria at the border areas of China and Myanmar.Benyun Shi Jinxin Zheng Hongjun Qiu Guo-Jing Yang Shang Xia Xiao-Nong Zhou 2017Infectious Diseases of Poverty2017,6,1:6
7沙尘PM_(10)质量浓度与气温的关系初探显示文摘利用甘肃民勤自动气象站观测的2004~2006年夏季的5 min一次的气温与沙尘PM10浓度资料,通过将数据分为实验组与对照组,研究了气温与沙尘天气之间的统计关系。个例显示,气温与沙尘PM10浓度之间存在降温、升温和混合型3种对应关系。实验组统计分析表明,气温及其变化(每5min间隔气温变化绝对值和每24 h间隔气温变化绝对值)与沙尘PM10浓度及其变化呈现出非常显著的正相关关系;沙尘暴天气下日平均气温变化与相应沙尘PM10浓度变化呈显著负相关。对照组结果表明,实验组统计关系是非常显著的。赵建华 Kyle Tietze Hongjun Zheng 隆霄 2012干旱气象2012,30,3:6

9Multiple-Stage Mineralization in the Huayangchuan U-REE-Mo-Cu-Fe Ore Belt of the Qinling Orogen,Central China:Geological and Re-Os Geochronological Constraints显示文摘The Huayangchuan ore belt is located in the western segment of Xiaoqinling Orogen in the southern margin of the North China Craton(NCC),and hosts voluminous magmatism and significant U-REE-Mo-Cu-Fe polymetallic mineralization.However,geochronological framework of the various mineralization phases in this region is poorly understood.Here,we present new Re-Os isochron ages on magnetite from the Caotan Fe deposit(2 675 ± 410 Ma,MSWD = 0.55),and on pyrite from the Jialu REE deposit(2 127 ± 280 Ma,MSWD = 1.9) and Yuejiawa Cu deposit(418 ± 23 Ma,MSWD =11.5),and Re-Os weighted average model age on pyrite from the Taoyuan Mo-U deposit(235 ± 14 Ma,MSWD = 0.17).These ages,combined with regional geology and mineralization ages from other deposits,suggest that mineralization in the Huayangchuan ore belt lasted from the Neoarchean to the Late Mesozoic.The mineralization corresponds to regional tectono-magmatic events,including the Neoarchean alkali magmatism(REE mineralization),Paleoproterozoic plagioclase-amphibolite emplacement(Fe mineralization),Paleoproterozoic pegmatite magmatism(U mineralization),Paleozoic Shangdan oceanic slab subduction-related arc magmatism(Cu mineralization),Early Mesozoic Paleo-Tethys Ocean subduction-related arc magmatism(Mo-U mineralization),and Late Mesozoic Paleo-Pacific oceanic plate subduction direction change-related Mo(-Pb) mineralization.We proposed that the Huayangchuan ore belt has undergone prolonged metallogenic evolution,and the magmatism and associated mineralization were controlled by regional geodynamic events.Hongjun Jiang Chunsi Yang Dequan Wang Hui Zheng Jie Li Huayong Chen 2022Journal of Earth Science2022,33,1:2

11Few-mode fibre-optic microwave photonic links显示文摘The fibre-optic microwave photonic link has become one of the basic building blocks for microwave photonics.Increasing the optical power at the receiver is the best way to improve all link performance metrics including gain,noise figure and dynamic range.Even though lasers can produce and photodetectors can receive optical powers on the order of a Watt or more,the power-handling capability of optical fibres is orders-of-magnitude lower.In this paper,we propose and demonstrate the use of few-mode fibres to bridge this power-handling gap,exploiting their unique features of small acousto-optic effective area,large effective areas of optical modes,as well as orthogonality and walk-off among spatial modes.Using specially designed few-mode fibres,we demonstrate order-of-magnitude improvements in link performances for single-channel and multiplexed transmission.This work represents the first step in few-mode microwave photonics.The spatial degrees of freedom can also offer other functionalities such as large,tunable delays based on modal dispersion and wavelength-independent lossless signal combining,which are indispensable in microwave photonics.He Wen Hongjun Zheng Qi Mo Amado Manuel Velázquez-Benítez Cen Xia Bin Huang Huiyuan Liu Huang Yu Pierre Sillard Jose Enrique Antonio Lopez Rodrigo Amezcua Correa Guifang Li 2017Light(Science & Applications)2017,6,1:2
