1Stratigraphy of the Triassic-Jurassic Boundary Successions of the Southern Margin of the Junggar Basin,Northwestern China显示文摘The Triassic-Jurassic(Tr-J) boundary marks a major extinction event,which(~200 Ma) resulted in global extinctions of fauna and flora both in the marine and terrestrial realms.There prevail great challenges in determining the exact location of the terrestrial Tr-J boundary,because of endemism of taxa and the scarcity of fossils in terrestrial settings leading to difficulties in linking marine and terrestrial sedimentary successions.Investigation based on palynology and bivalves has been carried out over a 1113 m thick section,which is subdivided into 132 beds,along the Haojiagou valley on the southern margin of the Junggar Basin of the northern Xinjiang,northwestern China.The terrestrial Lower Jurassic is conformably resting on the Upper Triassic strata.The Upper Triassic covers the Huangshanjie Formation overlaid by the Haojiagou Formation,while the Lower Jurassic comprises the Badaowan Formation followed by the Sangonghe Formation.Fifty six pollen and spore taxa and one algal taxon were identified from the sediments.Based on the key-species and abundance of spores and pollen,three zones were erected:the Late Triassic(Rhaetian) Aratrisporites-Alisporites Assemblage,the Early Jurassic(Hettangian) Perinopollenites-Pinuspollenites Assemblage,and the Sinemurian Perinopollenites-Cycadopites Assemblage.The Tr-J boundary is placed between bed 44 and 45 coincident with the boundary between the Haojiagou and Badaowan formations.Beds with Ferganoconcha(?),Unio-Ferganoconcha and Waagenoperna-Yananoconcha bivalve assemblages are recognized.The Ferganoconcha(?) bed is limited to the upper Haojiagou Formation, Unio-Ferganoconcha and Waagenoperna-Yananoconcha assemblages are present in the middle and upper members of the Badaowan Formation.The sedimentary succession is interpreted as terrestrial with two mainly lake deposit intervals within Haojiagou and Badaowan formations,yielding fresh water algae and bivalves.However,the presence of brackish water algae Tasmanites and the marine-littoral facies bivalve Waagenoperna from the Badaowan Formation indicate that the Junggar Basin was influenced by sea water caused by transgressions from the northern Tethys,during the Sinemurian.SHA Jingeng Vivi VAJDA PAN Yanhong Linda LARSSON YAO Xiaogang ZHANG Xiaolin WANG Yaqiong CHENG Xiansheng JIANG Baoyu DENG Shenghui CHEN Siwei PENG Bo 2011Acta Geologica Sinica(English Edition)2011,85,2:7
2Modeling and simulation of recurrent phenotypic and genomic selections in plant breeding under the presence of epistasis显示文摘Recurrent selection is an important breeding method for population improvement and selecting elite inbreds or fixed lines from the improved germplasm.Recently,a computer simulation tool called QuMARS has been developed,which allows the simulation and optimization of various recurrent selection strategies.Our major objective in this study was to use the QuMARS tool to compare phenotypic recurrent,marker-assisted recurrent,and genomic selections(abbreviated respectively as PS,MARS and GS)for both short-and long-termbreeding procedures.ForMARS,twomarker selection models were considered,i.e.,stepwise(Rstep)and forward regressions(Forward).For GS,three prediction models were considered,i.e.,genomic best linear unbiased predictors(GBLUP),ridge regression(Ridge),and regression by Moore-Penrose general inverse(InverseMP).To generate genotypes and phenotypes for a given individual during simulation,one additive and two epistasis genetic models were considered with three levels of heritability.Results demonstrated that selection responses from GBLUP-based GS and MARS(Forward)were consistently greater than those from PS under the additive model,particularly in early selection cycles.In contrast,selection response from PS was consistently superior over MARS and GS under epistatic models.For the two epistasis models,total genetic variance and the additive variance component were increased in some cases after selection.Through simulation,we concluded that GS and PS were effective recurrent selection methods for improved breeding of targeted traits controlled by additive and epistatic quantitative trait loci(QTL).QuMARS provides an opportunity for breeders to compare,optimize and integrate new technology into their conventional breeding programs.Mohsin Ali Luyan Zhang Ian DeLacy Vivi Arief Mark Dieters Wolfgang H.Pfeiffer Jiankang Wang Huihui Li 2020The Crop Journal2020,8,5:4
3Phase-shifting digital holography in image reconstruction显示文摘A phase-shifting digital holography scheme developed to investigate internal defects in artworks is described. Phase-shifting is utilized to obtain a clear reconstructed object wave from a rough surface texture. A reverse-transform algorithm is employed to reconstruct the object wave on its original position of unknown distance or the imaging position from the object wave information on the holographic plane. To get the clearest reconstruction the exact registration of the unknown distance is determined by applying the intensity sum as the auto-focusing function. The spatial resolution of the reconstruction image is also investigated for a variety of affecting factors. Laboratory results of reconstruction images under deformation are presented.于瀛洁 周文静 Yannis Orphanos Vivi Tornari 2006Journal of Shanghai University(English Edition)2006,10,1:3
4南半球白垩纪-古近纪之交生物灭绝期孢粉地层学显示文摘白垩纪-古近纪(K-Pg)生物大灭绝事件前后的孢粉植物群的变化,可以详细揭示植被对一场全球环境危机(6550万年前小行星撞击现今的墨西哥)的响应。在K-Pg界线处有一些植物门类灭绝了,因此孢粉地层学是确定非海相序列中白垩纪-古近纪界线的主要工具。南半球包括以下植物区:热带至亚热带棕榈植物大区,高纬度Nothofagidites/Proteacidites大区,以及一个含有混合的植物组分的过渡区域。在棕榈植物大区,一些马斯特里赫特期的关键物种在白垩纪-古近纪界线处灭绝了,包括Aquilapollenites magnus、Buttinia andreevi、Crassitricolporites brasiliensis、Proteaci ditesdehaani和Gabonisporis vigourouxii。在Nothofagidites/Proteacidites大区,Tricolporite slilliei、Triporopollenites sectilis、Quadraplanus brossus、Nothofagidites kaitangata和Grapnelispora evansii等物种最后出现于白垩纪-古近纪界线处。由此可见,我们需要对南半球与中国的K-Pg界线处的孢粉信息进行更详尽的分析,才能更详细地了解不同纬度、不同地点的植被对墨西哥尤卡坦撞击事件的响应。Vivi VAJDA Antoine BERCOVICI 2012地层学杂志2012,36,2:2
5花街·苦行僧·纽瓦丽式建筑 尼泊尔摄影手记显示文摘慧能刚到五祖弘忍门下时,弘忍问慧能从何处来?来作什么?惠能答道:我从岭南来,来学作佛。弘忍笑道:岭南蛮夷之人也能学佛吗?慧能不卑不亢地说:人有南北之分,佛性也有南北之分吗?这一刻顿悟,建筑本身也有'东西'之分吗?在古老的东方神韵中,也有一种别样的华丽的美。这一次我们仿佛偶入荒落而美丽的尼泊尔的旅人,来去匆匆却也从容,因为与佛同在的城市一定是安宁祥和的城市。但愿山西的那些建筑宝贝,我们也终究不会错过。还有欧洲那恬静深远精美的建筑留在我们心中的那一抹风情。东方也罢,西方也罢,建筑的形态终究会摆脱来自结构的,地域的和惯性思维的束缚,我们只要在这样的建筑里面能找到和自己心灵相沟通的元素,又何来'东西'之分呢?谭建华 Vivi HE Ying 2008中外建筑2008,,1:2
6低氧应激因子PHD2与血管新生相关疾病显示文摘PHDs家族是低氧应激的重要调控因子,通过调控低氧诱导因子HIFs的稳定性和活性,使细胞和组织适应低氧应激环境。其中,PHD2作为PHDs家族中的重要一员,是低氧诱导因子HIF-1的关键调控因子。近年研究表明,PHD2不仅在缺血性疾病的血管新生中起重要作用,还能通过调控肿瘤生长、转移等相关基因的表达,影响肿瘤微环境下肿瘤的生长及转移。本文就PHD2的分子调控机制及其在生理病理过程中的作用机制进行综述,重点介绍PHD2在血管再生治疗和肿瘤血管新生中的作用,以及目前PHD2作为治疗靶标的开发应用研究。贾慧珍 2014药学学报2014,49,2:2
7A symmetry concept and significance of fringe patterns as a direct diagnostic tool in artwork conservation显示文摘Previous collaborative studies have shown the main fringe patterns and their typical classification with regard to defects.Nevertheless,the complexity of the results prevents defect detection automation based on a fringe pattern classification table.The use of fringe patterns for the structural diagnosis of artwork is important for conveying crucial detailed information and dense data sources that are unmatched compared to those obtained using other conventional or modern techniques.Hologram interferometry fringe patterns uniquely reveal existing and potential structural conditions independent of object shape,surface complexity,material inhomogeneity,multilayered and mixed media structures,without requiring contact and interaction with the precious surface.Thus,introducing a concept that from one hand allows fringe patterns to be considered as a powerful standalone physical tool for direct structural condition evaluation with a focus on artwork conservators'need for structural diagnosis while sets a conceptual basis for defect detection automation is crucial.The aim intensifies when the particularities of ethics and safety in the field of art conservation are considered.There are ways to obtain the advantages of fringe patterns even when specialized software and advanced analysis algorithms fail to convey usable information.Interactively treating the features of fringe patterns through step-wise reasoning provides direct diagnosis while formulates the knowledge basis to automate defect isolation and identification procedures for machine learning and artificial intelligence(AI)development.The transfer of understanding of the significance of fringe patterns through logical steps to an AI system is this work's ultimate technical aim.Research on topic is ongoing.Vivi Tornari 2022Light(Advanced Manufacturing)2022,3,2:2
