New fossil eccoptarthrids (Coleoptera: Curculionoidea) from the Yixian Formation of western Liaoning, China

One new genus and three new species of the weevil family Eccoptarthridae (Curculionoidea), Leptocar polychaetus gen. et sp. nov., Abrocar macilentus sp. nov., Cretonanophyes punctatus sp. nov., are described and illustrated. They pertain to the Upper Jurassic or Lower Cretaceous Yixian Formation of western Liaoning Province, China. The host plants to the living eccoptarthrids and the floras in Yixian Formation indicate that those archaic eccoptarthrids possibly lived on conifers with a phylogenetic closeness to Cupressaceae. Besides, the early diversification of eccoptarthrids is discussed: origi- nated in Central or East Asia in the Late Jurassic, spread into Western Europe and South America during the Early Cretaceous, underwent a dramatic decline after the Early Cretaceous which likely was caused by competitive pressure and the displacement of their host plants.     

Numerical Weather Prediction in China in the New Century ——Progress, Problems and Prospects

This paper summarizes the recent progress of numerical weather prediction(NWP)research since the last review was published.The new generation NWP system named GRAPES(the Global and Regional Assimila- tion and Prediction System),which consists of variational or sequential data assimilation and nonhydrostatic prediction model with options of configuration for either global or regional domains,is briefly introduced, with stress on their scientific design and preliminary results during pre-operational implementation.In ad- dition to the development of GRAPES,the achievements in new methodologies of data assimilation,new improvements of model physics such as parameterization of clouds and planetary boundary layer,mesoscale ensemble prediction system and numerical prediction of air quality are presented.The scientific issues which should be emphasized for the future are discussed finally.     

论工程岩体完整性的评价方法

目前国内外对工程岩体完整性的评价方法很多,均从某一侧面间接反映了岩体的完整程度,缺乏科学性.结合工程勘察实践及相关学科的研究,对岩体完整性评价,建立了KY、RID新公式,提高了工程岩体完整程度评价方法的科学性.

The ethno-class trajectory of new neighborhoods in Israel

The subject of this article falls within the debate on the development of new neighborhoods beyond the hub of the metropolis and how this relates to planning from below. It regards new neighborhoods as being increasingly shaped through deliberate action in the form of public policy at the state and local levels. However, it emphasizes the central role of the government establishment, national institutions and ideologies in walling out and exclusionary practices. Research into four representative new neighborhoods in Israel, which were planned under the new spatial regime of the 1990s, reveals patterns of discrimination and ethno-class stratification that enable the preservation of nationalism and ethnic logic as the main, yet concealed, axis organizing social and spatial life.

Application of nonlinear forecasting techniques for meteorological modeling

A nonlinear forecasting method was used to predict the behavior of a cloud coverage time series several hours in advance. The method is based on the reconstruction of a chaotic strange attractor using four years of cloud absorption data obtained from half-hourly Meteosat infrared images from Northwestern Spain. An exhaustive nonlinear analysis of the time series was carried out to reconstruct the phase space of the underlying chaotic attractor. The forecast values are used by a non-hydrostatic meteorological model ARPS for daily weather prediction and their results compared with surface temperature measurements from a meteorological station and a vertical sounding. The effect of noise in the time series is analyzed in terms of the prediction results.
