1Eastern Asian endemic seed plant genera and their paleogeographic history throughout the Northern Hemisphere显示文摘We review the fossil history of seed plant genera that are now endemic to eastern Asia. Although the majority of eastern Asian endemic genera have no known fossil record at all, 54 genera, or about 9%, are reliably known from the fossil record. Most of these are woody (with two exceptions), and most are today either broadly East Asian, or more specifically confined to Sino-Japanese subcategory rather than being endemic to the Sino-Himalayan area. Of the 'eastern Asian endemic' genera so far known from the fossil record, the majority formerly occurred in Europe and/or North America, indicating that eastern Asia served as a late Tertiary or Quaternary refugium for taxa. Hence, many of these genera may have originated in other parts of the Northern Hemisphere and expanded their ranges across continents and former sea barriers when tectonic and climatic conditions al- lowed, leading to their arrival in eastern Asia. Although clear evidence for paleoendemism is provided by the gymnosperms Amentotaxus, Cathaya, Cephalotaxus, Cunninghamia, Cryptomeria, Glyptostrobus, Ginkgo, Ketel-eeria, Metasequoia, Nothotsuga, Pseudolarix, Sciadopitys, and Taiwania, and the angiosperms Cercidiphyllum, Choerospondias, Corylopsis, Craigia, Cyclocarya, Davidia, Dipelta, Decaisnea, Diplopanax, Dipteronia, Em-menopterys, Eucommia, Euscaphis, Hemiptelea, Hovenia, Koelreuteria, Paulownia, Phellodendron, Platycarya, Pteroceltis, Rehderodendron, Sargentodoxa, Schizophragma, Sinomenium, Tapiscia, Tetracentron, Toricellia, Trapella, and Trochodendron, we cannot rule out the possibility that neoendemism plays an important role especially for herbaceous taxa in the present-day flora of Asia, particularly in the Sino-Himalayan region. In addition to reviewing paleobotanical occurrences from the literature, we document newly recognized fossil occurrences that expand the geographic and stratigraphic ranges previously known for Dipelta, Pteroceltis, and Toricellia.Steven R.

2Pharmacokinetics of radioimmunotherapeutic agent of direct labeling mAb ^(188)Re-HAb18显示文摘AIM: To labed Anti-hepatoma monoclonal antibody (mAb)fragment HAb18 F (ab')2 was labeled with 188 Re for thepharmacokinetic model of 188 Re-HAb18 F (ab')2 and toevaluate its pharmacokinetic parameters in hepatoma-bearing nude mice.METHODS: HAb18 F(ab')2 was directly labeled with 188Reusing 2-mercaptoethanol (2-ME) as reducing agents.Labeling efficiency and immunoreactivity of 188 Re-HAb18 F( ab')2 were evaluated by Whatman 3MM paperchromatography and live cell assay, respectively.Biodiatribution analysis was also conducted in nude micebearing human hepatoma in which animals were sacrificed atdifferent time points(1, 4, 18, 24 and 24h) after 188Re-HAb18F(ab' )2 was injected through tail-vein into hepatoma-bearingnude mice. The blood and radioactivity of organs and masswere measured. The concentrations of 188 Re-HAb18 F(ab')2were evaluated with a pharmacokinetic 3P97 software.RESULTS: The optimum labeling efficiency andimmunoreactive fraction were 91.7% and 0.78%,respectively. The parameters of 188Re-HAb18 F(ab')2 were:T1/2, 2.29h; Vd, 1.49 × 10-9L@ Bq- 1; AUC, 20.49 × 109Bq@ h@L-1 ;CL, 0.45 × 10-3L@ h- 1. 188Re- HAb18 F(ab')2 could locatespecially in hepatoma with high selective reactivity of HAb18F(ab')2. 188 Re-HAb18 F(ab')2 was mainly eliminated bykidney. The maximal tumor to blood ratio was at 48h, andmaximal tumor to liver ratio was at 18h.CONCLUTION: The pharmacokinetics of 188Re-HAb18 F(ab')2fit a I-compartment model. 188 Re-HAb18 F(ab')2 can beuptaken selectively at the hepatoma site.Chao Lou Zhi-Nan Chen Hui-Jie Bian Department of Cell Engineering Research Centre,Jie Li,Department of Oral Cell Biology,Qingdu Hospital,Fourth Military Medical University,Xi’an 710033,Shaanxi Province,China Shou-Bo Zhou School of Biological Sciences,University of Manchester,Oxford Road,United Kingdom 2002World Journal of Gastroenterology2002,8,1:14

4Searching for the Nano-Hertz Stochastic Gravitational Wave Background with the Chinese Pulsar Timing Array Data ReleaseⅠ显示文摘Observing and timing a group of millisecond pulsars with high rotational stability enables the direct detection of gravitational waves(GWs).The GW signals can be identified from the spatial correlations encoded in the times-of-arrival of widely spaced pulsar-pairs.The Chinese Pulsar Timing Array(CPTA)is a collaboration aiming at the direct GW detection with observations carried out using Chinese radio telescopes.This short article serves as a“table of contents”for a forthcoming series of papers related to the CPTA Data Release 1(CPTA DR1)which uses observations from the Five-hundred-meter Aperture Spherical radio Telescope.Here,after summarizing the time span and accuracy of CPTA DR1,we report the key results of our statistical inference finding a correlated signal with amplitude logA_(c)=-14.4_(-2.8)^(+1.0)for spectral index in the range ofα∈[-1.8,1.5]assuming a GW background(GWB)induced quadrupolar correlation.The search for the Hellings–Downs(HD)correlation curve is also presented,where some evidence for the HD correlation has been found that a 4.6σstatistical significance is achieved using the discrete frequency method around the frequency of 14 n Hz.We expect that the future International Pulsar Timing Array data analysis and the next CPTA data release will be more sensitive to the n Hz GWB,which could verify the current results.Heng Xu Siyuan Chen Yanjun Guo Jinchen Jiang Bojun Wang Jiangwei Xu Zihan Xue RNicolas Caballero Jianping Yuan Yonghua Xu Jingbo Wang Longfei Hao Jingtao Luo Kejia Lee Jinlin Han Peng Jiang Zhiqiang Shen Min Wang Na Wang Renxin Xu Xiangping Wu Richard Manchester Lei Qian Xin Guan Menglin Huang Chun Sun Yan Zhu 2023Research in Astronomy and Astrophysics2023,23,7:3

6Robust fault diagnosis for non-Gaussian stochastic systems based on the rational square-root approximation model显示文摘The task of robust fault detection and diagnosis of stochastic distribution control(SDC) systems with uncertainties is to use the measured input and the system output PDFs to still obtain possible faults information of the system. Using the rational square-root B-spline model to represent the dynamics between the output PDF and the input,in this paper,a robust nonlinear adaptive observer-based fault diagnosis algorithm is presented to diagnose the fault in the dynamic part of such systems with model uncertainties. When certain conditions are satisfied,the weight vector of the rational square-root B-spline model proves to be bounded. Convergency analysis is performed for the error dynamic system raised from robust fault detection and fault diagnosis phase. Computer simulations are given to demonstrate the effectiveness of the proposed algorithm.YAO LiNa1 & WANG Hong2,3 1 School of Electrical Engineering,Zhengzhou University,Zhengzhou 450001,China 2 Control Systems Centre,University of Manchester,Manchester M60 1QD,UK 3 Institute of Automation,Chinese Academy of Sciences,Beijing 100080,China 2008Science in China(Series F)2008,51,9:3
