歌海娜是一种历史悠久且备受欢迎的葡萄品种,承载着丰富的历史故事,其起源可以追溯到公元前四世纪。中国人对酒的浪漫是刻在骨子里的,一个最直观的体现就是名字,即使是音译,也并不直截了当,而总是试图在原音的基础上找到契合其特色和气质的译名,让酒客们在品酒之时,似乎更能触碰到酒的“灵魂”。很多为中国消费者所熟知的酿酒葡萄品种都有既好听又令人印象深刻的中文译名,比如长相思、赤霞珠、仙粉黛、霞多丽等等,歌海娜无疑也是其中之一。

Group dynamics and relocation decisions of a trap-building predator are differentially affected by biotic and abiotic factors

Current Zoology 2017年第6期63卷 647-655页

Most habitats in nature are heterogeneous, incorporating favorable and unfavorable microhabitats for different animals, based on their ecological niche. Unsuitable microhabitats have negative consequences for individual growth and survival. Animals, therefore, should fine-tune their location within the habitat by dispersing away from such microhabitats. We studied the suitability of different constant microhabitat conditions for wormlion larvae, a trap-building predator, tested in groups under laboratory conditions. Wormlions construct pit-traps in loose soil and capture small arthropod prey. As wormlions occur in high densities in nature, testing in groups is thus more indicative of their natural behavior than testing individuals. Wormlions responded strongly to biotic conditions--high conspecific density, starvation, and large body mass of conspecifics--by either increasing pit-relocation events or moving away from the microhabitat center to the periphery of the arena, probably opting for a way out. In other instances, individuals increased their distance to the nearest neighbor, thereby changing the spatial pattern toward a more regular pattern, potentially indicating interference competition. The only abiotic condition apparently perceived by wormlions as unsuitable was shallow sand, which led to frequent relocations. The two other abiotic factors--illumination and sand particle size--had no observable effect on behavior, although wormlions in nature always occur under shade in fine sand, and prefer both shade and fine sand particle size under laboratory conditions when given a choice. Under the fine spatial scale of the present experiment, biotic factors appear to be more influential than abiotic ones.

Return and Volatility Spillovers Effects:Study of Asian Emerging Stock Markets

Journal of Systems Science and Information 2018年第2期9卷 97-119页

This paper examines the extent of contagion and interdependence across the six Asian emerging countries stock markets(e.g., Bangladesh, China, India, Malaysia, the Philippine, and South Korea) and then try to quantify the extent of the Asian emerging market fluctuations which are described by intra-regional contagion effect. These markets experienced both fast growth and key upheaval during the sample period, and thus, provide potentially rich information on the nature of border market interactions. Using the daily stock market index data from January 2002 to December 2016(breaking the 15 years data set into three sub periods; pre-crisis, crisis, and post crisis periods);particularly make attention to the global financial crisis of 20072008. The return and volatility spillovers are modeled through the GARCH(generalized autoregressive conditional heteroscedasticity),pairwise Granger causality tests, and the forecast error variance decomposition in a generalized VAR(vector auto regression) models. This paper shows that volatility and return spillovers behave very differently over time, during the pre-crisis, crisis, and post crisis periods. Importantly, Asian emerging stock markets interaction is less before the global financial crisis period. The return and volatility spillover indices touch their respective historical peaks during the global financial crisis 20072008,however Bangladeshi market faces this condition in 20092010.

The effect of anodic polarization on the plastic deformation behavior and formability of FeSi6.5 steel at room temperature was experimentally investigated through uniaxial tensile and drawing of wire specimen in sulfuric acid solution with current densities of 0-40 mA/*** formability of the FeSi6.5 steel was significantly improved after the anodic *** plastic elongation of the specimen as an anode in the electrochemical environment was 4.4%-7%,but 2.7%in the *** drawing force under the anodic polarization decreased by 12.5%-26%compared to that in deionized *** softening is mainly attributed to the relief in work hardening caused by surface atomic *** work hardening mechanism of the FeSi6.5 steel wires under anodic polarization condition was analyzed using Hollomon equation and Voce relation combined with the Kocks-Mecking *** data support the view that the surface atom dissolution facilitates dislocation ***6.5 steel wires were obtained using electrochemical cold drawing and presented a smooth surface and good ductility without crack after five-pass drawing with a total cross-section area reduction of 88%.The drawing with the assistance of anodic polarization is a promising technology for processing hard and brittle metal materials.
