孢粉-气候定量重建方法体系的建立及其应用——以青藏高原东部全新世温度重建为例

第十八届全国量子光学学术会议

作者：李伯鹏 y.Guo L.Zhang D.Huang 中南大学 Sc.ool of Information Sc.enc. & Engineering Central South University

c.ec.-node-based globally.c.upled low-density.parity.c.ec.(c.-Gc.LDPc. is a spec.al ty.e of LDPc.c.des. The c.-Gc.LDPc.s Tanner graph c.mprises a set of disjoint Tanner graphs whic. are c.nnec.ed together by.a group of overall c.ec.-nodes(c.s), c.lled global c.s. Rec.nc.liation is a signific.nt proc.dure in a c.ntinuous-variable quantum key.distribution(c.-QKD) sy.tem. In this paper, we propose a high performanc. rec.nc.liation sc.eme through employ.ng a modified two-phase loc.l/global iterative dec.ding sc.eme based on c.-Gc.LDPc. By.using this rec.nc.liation sc.eme, the c.-QKD sy.tem’s rec.nc.liation effic.enc. c.n reac. 98.48%. The gaps between the iterative dec.ding thresholds and the Shannon limits are very.small. The proposed sc.eme has lower enc.ding c.mplexity.c.mpared to the c.nventional rec.nc.liation sc.eme. By.using a graphic. proc.ssing unit(GPU), the rec.nc.liation sc.eme c.n reac. a high speed for a c.-QKD sy.tem.

长时间尺度气候变化的定量重建结果可为理解气候自然变率及其机制提供参考,并为气候模拟提供边界条件与验证.然而,由于已有定量重建方法体系并不完善,许多重建结果的可信度存在很大不确定性.本研究建立了一个基于高质量现代孢粉数据库的定量重建方法体系:包括现代孢粉数据筛选、训练集选择、主控气候因子分析、最优模型建立、评估检验和生态解释等多个步骤.将该方法体系应用于青藏高原东部若尔盖盆地的三个高分辨率孢粉记录,定量重建了研究区全新世温度变化.结果表明,全新世早期最暖月温度(MTwa)约为10.4℃,随后温度逐步升高,在8.5~6ka BP达到全新世最高(约11℃).经历了早、中全新世的温暖气候后,温度持续降低1.2℃,在新冰期期间达到全新世温度最低值.除全新世整体变冷趋势外,MTwa还具有明显的500年周期波动,其信号强度随时间有所波动.温度的高(低)值与太阳活动的最大值(最小值)同相位变化,这表明青藏高原东部地区百年尺度气候波动很可能受到了太阳活动的影响.

海洋是地球上最大的碳库,发挥着全球气候变化"缓冲器"的作用.蓝色碳汇,简称"蓝碳",即由海洋生态系统捕获的碳(主要是有机碳),是海洋储碳的重要机制之一.蓝碳最初认识的形式是可见的海岸带植物固碳.其实之前没有得到足够重视的、看不见的微型生物(浮游植物、细菌、古菌、病毒、原生动物)占海洋生物量9 0%以上,是蓝碳的主要贡献者.中国陆架边缘海占国土总面积的1/3,碳汇潜力巨大,亟待研发.本文以近海生态系统碳汇过程、调控机制及增汇模式为主线,论述了近海生态系统结构与碳循环功能特征、碳汇形成过程与机理,并结合近海碳汇在沉积记录中的地史过程演变探讨了自然过程和人类活动对碳汇的可能影响,展望了碳汇工程在增加近海海洋储碳能力方面的应用前景.

作者： Lee S.E. Kim H.-y. Jung S.-E. W.-K. Kim 王一飞 Department of Pediatric.Surgery Seoul National University Children's Hospital Seoul 110-744 South Korea

Bac.ground/Purpose: The aim of the study.was to review the gastrointestinal abnormalities oc.urring in assoc.ation with situs anomalies. Methods: Patients with situs anomalies were identified from the medic.l rec.rds of pediatric.patients of Seoul National University.c.ildren’s Hospital from January.1980 to July.2004. Retrospec.ive study.was undertaken. Diagnosis was made on the basis of the information obtained from a c.mbination of ec.oc.rdiography. angiography. abdominal ultrasonography. liver sc.n, upper gastrointestinal study. or abdominal c.mputed tomography. Results: A total 67 patients diagnosed as having situs anomalies were identified. There were 40 males and 26 females (1.54:1). Of these 67 patients,45 patients (67%) were diagnosed as having situs inversus, 16 patients (24%) as having right isomerism, and 6 patients (9%) as having left isomerism. Of 45 patients with situs inversus, there were 26 patients (58%) who had intraabdominal *** were duodenal atresia, biliary.atresia, gastrosc.isis with malrotation, c.ngenital hepatic.fibrosis, trac.eoesophageal fistula(ty.e c., c.rrarino’s triad, and pheoc.romoc.toma. Of 16 patients with right isomerism, there were 14 patients (88%)who had intraabdominal abnormalities. These were hiatal hernia and diaphragmatic.hernia. Of 6 patients with left isomerism, there were 4 patients (67%) who had intraabdominal *** were malrotation and biliary.atresia. c.nc.usion: When a patient is noted to have c.ngenital heart disease as part of situs anomalies, or if an aty.ic.l position of organs is noted at imaging evaluation, we rec.mmend that the patient undergo c.est radiography. abdominal ultrasonography. upper gastrointestinal study. and abdominal c.mputed tomography.

目的对单纯腭裂并全面性癫伴热性惊厥附加症家系进行基因定位,并对候选基因GABRD进行测序研究。方法对家系进行全基因组扫描两点间连锁分析,设计GABRD基因9对外显子-内含子交界处内含子引物,Pc.扩增患者及健康对照GABRD基因组序列,测序采用Sanger双脱氧链终止法,Pc.产物直接测序,对比分析患者的突变序列及健康对照序列。结果两点连锁分析在1p36区域最大LOD值为1.68。GABRD基因测序显示第4外显子患者的序列分别为T/c.T/T,健康对照的序列分别为T/T和A/c.编码序列分析GGT、GGc.GGA均为甘氨酸。患者GABRD基因mRNA碱基序列为c.25T多态性。GABRD第7外显子患者的序列分别为c.T和T/T,健康对照分别为T/T和c.c.异常序列位于mRNA第911碱基处,编码分析AGT及AGc.编码丝氨酸。患者的碱基序列出现了T911c.态性。结论单纯腭裂并全面性癫伴热性惊厥附加症致病基因在1p36区域取得一定的连锁关系,在该家系未发现突变基因;所发现的c.25T和T911c.个碱基多态性为其他腭裂及癫家系的连锁分析、关联分析及分子遗传学研究提供了依据。

羊水粪染与孕周及新生儿酸碱平衡状态

OBJEc.IVE: To estimate whether the ac.d-base status of neonates born to women with mec.nium-stained amniotic.fluid varies ac.oss gestation. METHODS: We c.rried out a retrospec.ive c.hort study.of all pregnanc.es that were c.mplic.ted by.mec.nium-stained amniotic.fluid in 2004. c.ses were identified from a perinatal pathology.database that c.ntained data on all pregnanc.es c.mplic.ted by.mec.nium- stained amniotic.fluid. Data abstrac.ed from the c.arts inc.uded gestational age at delivery. umbilic.l arterial pH, birth weight, and the presenc. or absenc. of labor. c.ses were stratified ac.ording to gestational age at delivery. The distribution of mec.nium-stained amniotic.fluid ac.oss gestation was c.mputed. The mean umbilic.l arterial pH values (with 95% c.nfidenc. intervals) ac.oss gestation were assessed by.analy.is of varianc.. RESULTS: The mean umbilic.l arterial pH in women with mec.nium-stained amniotic.fluid did not differ ac.oss gestation. The overall inc.denc. of mec.nium-stained amniotic.fluid was 12.0% (766 of 6,403 deliveries). The rates of mec.nium-stained amniotic.fluid inc.eased from 1.2% at 32 weeks to 100% at 42 weeks. c.Nc.USION: The rising inc.denc. of mec.nium-stained amniotic.fluid with gestational age is c.nsistent with the hy.othesis that fetal maturation is a major etiologic.fac.or in mec.nium passage. Also, the lac. of variation of mean umbilic.l arterial pH ac.oss gestation suggests that fetal ac.demia is not inc.eased when mec.nium passage oc.urs earlier in pregnanc. rather than at later gestational ages.

Demographic.c.anges during the late Pleistoc.ne-Holoc.ne left signatures in the DNA of c.ntemporary.populations. These signatures reveal demographic.phenomena like the inc.ease or dec.ease in effec.ive population size. In this paper we searc.ed for signatures of demographic.c.ange in the DNA of the Neotropic.l freshwater fish Poec.lia vivipara. Also, we investigated whether demographic.c.anges are c.rrelated with palaeoc.imatic.events of the late Pleistoc.ne-Holoc.ne, in partic.lar, if c.anges in effec.ive population size are c.rrelated with expansion and c.ntrac.ion of available habitats, induc.d by.global ic.-volume c.anges and sea-level fluc.uations. We used Bay.sian Sky.ine Plot (BSP) analy.is with sequenc.s from the mitoc.ondrial gene c.toc.rome b to estimate the anc.stral demography.of the Neotropic.l freshwater fish P. vivipara. To test the assumptions of neutrality.and absenc. of population struc.ure we used Tajima’s D and Spatial Analy.is of Molec.lar Varianc. (SAMOVA), respec.ively. Effec.ive population size of P. vivipara remained stable until 75,000 y.ars ago, inc.eased by.10-fold reac.ing a maximum at approximately.25,000 y.ars ago, then suddenly.dec.ined at the Pleistoc.ne-Holoc.ne boundary. Variation in effec.ive population size in P. vivipara c.rrelates with expansion and c.ntrac.ion of habitats induc.d by.sea-level fluc.uations, c.used by.the advanc. and retreat of ic. sheets during the Last Glac.al Maximum (LGM).
