Thirteen loci were found to express polymorphisms ranging from two to 17 alleles. The eight most variable loci were selected to set up and optimize two multiplex polymerase chain reaction （PCR） assays. Three populations containing altogether 436 trees were used to characterize the selected loci and ascertain their applicability for parentage analysis and genotyping studies. Through cross-checking of clonal identity against sex of the genotyped trees we estimated the maximum error rate for merging genotypes to be less than 0.045.展开更多

Two versions of CICE are validated through comparison with Hadley Centre Global Sea Ice and Sea Surface Temperature(Had ISST) observations. Version 5.0 of CICE with elastic-viscous-plastic(EVP) dynamics simulates a September Arctic sea ice concentration(SASIC) trend of –0.619 × 1012 m2 per decade from 1969 to 2009, which is very close to the observed trend(-0.585 × 1012 m2 per decade). Version 4.0 of CICE with EVP dynamics underestimates the SASIC trend(-0.470 × 1012 m2 per decade). Version 5.0 has a higher correlation(0.742) with observation than version 4.0(0.653). Both versions of CICE simulate the seasonal cycle of the Arctic sea ice, but version 5.0 outperforms version 4.0 in both phase and amplitude. The timing of the minimum and maximum sea ice coverage occurs a little earlier(phase advancing) in both versions. Simulations also show that the September Arctic sea ice volume(SASIV) has a faster decreasing trend than SASIC.展开更多

This coupled model was developed and maintained at the State Key Laboratory of Atmospheric Sciences and Geophysical Fluid Dynamics (LASG). There are two steps in our hindcast experiments. The first is to integrate the coupled model continuously with sea surface temperature (SST) nudging, from 1971 to 2006. The second is to carry out a series of one-year hindcasts without SST nudging, by adopting initial values from the first step on January 1 st , April 1st , July 1st , and October 1st , from 1982 to 2005. We generate 10 ensemble members for a particular start date (1st ) by choosing different atmospheric and land conditions around the hindcast start date (1st through 10th ). To estimate the predicted SST, two methods are used: (1) Anomaly Correlation Coefficient and its rate of decrease; and (2) Talagrand distribution and its standard deviation. Results show that FGOALS-g offers a reliable ensemble system with realistic initial atmospheric and oceanic conditions, and high anomaly correlation (>0.5) within 6 month lead time. Further, the ensemble approach is effective, in that the anomaly correlation of ensemble mean is much higher than that of most individual ensemble members. The SPB exists in the FGOALS-g ensemble system, as shown by anomaly correlation and equal likelihood. Nevertheless, the role of the ensemble mean in reducing the SPB of ENSO prediction is significant. The rate of decrease of the ensemble mean is smaller than the largest deviations by 0.04-0.14. At the same time, the ensemble system "equal likelihood" declines during spring. An ensemble mean helps give a correct prediction direction, departing from largely-deviated ensemble members.展开更多

The added value of rainfall simulation relative to reanalysis data and the sources of model bias were studied. Results showed that the model simulated rainfall anomalies moderately well. The model did well at capturing the above-normal rainfall along the Yangtze River valley （YRV） during E1 Nifio decaying summers and the below and above-normal rainfall centers along the YRV and the Huaihe River valley （HRV）, respectively, during La Nifia decaying summers. These features were not evident in rainfall products derived from the reanalysis, indicating that rainfall simulation did add value. The main limitations of the model were that the simulated rainfall anomalies along the YRV were far stronger and weaker in magnitude than the observations during E1 Nifio decaying summers and La Nifia decaying summers, respectively. The stronger magnitude above-normal rainfall during E1 Nifio decaying summers was due to a stronger northward transport of water vapor in the lower troposphere, mostly from moisture advection. An artificial, above-normal rainfall center was seen in the region north to 35°N, which was associated with stronger northward water vapor transport. Both lower tropospheric circulation bias and a wetter model atmosphere contributed to the bias caused by water vapor transport. There was a stronger southward water vapor transport from the southern boundary of the model during La Nifia decaying summers; less remaining water vapor caused anomalously weaker rainfall in the model as compared to observations.展开更多

Compared with the interior design activities, the furniture is one of the important factors in the process of the interior decoration. The choice of the appropriate furniture not only can effectively improve the quality of the interior design activities, but also can fully meet the specific application needs of the people. This paper starts from the analysis of the specific requirements on the design and production of the modern furniture. And combined with the analysis of the specific characteristics and the connotation of the design styles of the furniture in the Ming Dynasty, the author further explores the specific influence of the design styles of the Ming Dynasty furniture on the modern furniture.展开更多

Pu Songling answers this question with his work Liao zhai zhi yi （Strange tales from a Chinese studio）. This paper aims to study his narrative arts. There are four sections included. In part 1, this paper introduces a definition of the aesthetic dialectics and its embodiment in Chinese classical literary theory; in part 2, this paper takes the Liao zhai story as example to interpret Pu Songling＇s dialectic relation between description and narration; in part 3, I will show how Liao zhai presents beauty by unexpected but reasonable changes; and in last part, I give more importance to the stories concerning ordinary things for the reason that Pu Songling could make them interesting and beautiful. In the end, the paper concludes that Pu Songling is successful storyteller by using dialectic arts, which should be learned by Chinese writers.展开更多

Special values in research have ancient genera and species, which include representatives ofNymphaeaceae salisb, and trapaceae Dumort. families, 22 species, 6 varieties, 1 hybrid, 30 cultivars of which are presented in collection of garden in open and covered soil. For the first time in covered soil of two conservatories ecological modeling was conducted. Placement of plants is done in form of 5 models of artificial ecotopes, in 155 abatises. Four ecobiomorphological groups based on rhizome system were determined for Nymphaeaceae, among which conditionally-rhizome and conditionally-stolone are provided for the first time.展开更多

Dermatophytes were identified from rabbit sample cultures submitted to mycological examination in the Laboratory of Microbiology of the University of Tr^-os-Montes e Alto Douro, Vila Real, Portugal. All samples were collected from suspected clinical cases. Dermatophytes were cultured from 4 of the 55 specimens （7.3%）. The dermatophytes isolated were Trichophyton mentagrophytes var. mentagrophytes （1.8%） and Microsporum gypseum （5.5%）. Microscopic examination was negative in all specimens. In this work, Scopulariopsis spp., a contaminant mould, was identified in 13 specimens （23.6%）. The proportion of positive samples in relation to the number of samples examined from cases suspected was very low. As all samples were collected from rabbits with compatible signs, we presume that the low prevalence of isolation was due to laboratory constraints on dermatophytes diagnosis.展开更多
