This paper discusses the role of Hong Kong in China＇s grand scheme to build up the RMB as a global reserve currency. We highlight the economic importance of Hong Kong to China in terms of channeling foreign direct investment into China, some of which, in the future, will be denominated in the RMB. We discuss the development of China＇s RMB currency swap and deposit markets in Hong Kong. These offshore markets enable the RMB to trade freely, setting the stage for the RMB to become fully convertible and allowing market forces to play a role in pricing the value of the RMB, and help in the development of the RMB-denominated bond （or dim sum bond） market in Hong Kong. Finally, we present evidence of the phenomenal growth of the dim sum bond market in Hong Kong, which can further enhance and strengthen the use of the RMB outside China.

Psychological depression is drawing accumulating attention nowadays, due to the skyrocketing incidence worldwide and the enormous burdens it incurs. Physical exercise has been long recog- nized for its therapeutic effects on depressive disorders, although knowledge of the underlying mechanisms remains limited. suppressed hippocampal neurogenesis in adult brains has been regarded, at least partly, contributive to depression, whereas physical exercise that restores neuro- genesis accordingly exerts the anti-depressive action. several recent publications have suggested the potential role of adiponectin, a protein hormone secreted by peripheral mature adipocytes, in mediating physical exercise-triggered enhancement of hippocampal neurogenesis and alleviation of depression. Here, we briefly review these novel findings and discuss the possibility of counter- acting depression by modulating adiponectin signaling in the hippocampus with interventions including physical exercise and administration of pharmacological agents.

Most organic materials for optoelectronic applications are conjugated organic system. The burgeoning synthetic methodologies using organometallic catalysts or reagents have provided a powerful arsenal to design and synthesize new conjugated organic materials. It is particularly noteworthy that carbon-carbon bond formation involving a Csp2 or Csp at the reaction center can readily be achieved. For examples, cross-coupling reactions (e.g. Kumada-Corriu reaction, stille reaction, and suzuki reaction) are extremely powerful for the synthesis of Csp2-Csp2 single bond. sonogashira reaction, on the other hand, serves as a useful entry for the preparation of alkynylarenes or conjugated enynes. Heck reaction furnishes a coupling between an aryl halide and an alkene. Alternatively, olefination reactions provides a practical route for the synthesis of carbon-carbon double bond. In the past decade, we have uncovered four new kinds of transformations staring from the dithioacetal functionality (scheme).1,2 Three of them have been employed in the synthesis of conjugated small molecules as well as conjugated oligomers/polymers. Their syntheses, photophysical as well as electroluminescent properties will briefly be discussed. 　　……

Cloud microphysical processes occur at the smallest end of scales among cloud-related processes and thus must be parameterized not only in large-scale global circulation models(GCMs)but also in various higher-resolution limited-area models such as cloud-resolving models(CRMs)and large-eddy simulation(LEs)*** of giving a comprehensive review of existing microphysical parameterizations that have been developed over the years,this study concentrates purposely on several topics that we believe are understudied but hold great potential for further advancing bulk microphysics parameterizations:multi-moment bulk microphysics parameterizations and the role of the spectral shape of hydrometeor size distributions;discrete vs“continuous”representation of hydrometeor types;turbulence-microphysics interactions including turbulent entrainment-mixing processes and stochastic condensation;theoretical foundations for the mathematical expressions used to describe hydrometeor size distributions and hydrometeor morphology;and approaches for developing bulk microphysics *** presented are the spectral bin scheme and particle-based scheme(especially,super-droplet method)for representing explicit *** advantages and disadvantages are elucidated for constructing cloud models with detailed microphysics that are essential to developing processes understanding and bulk microphysics ***-resolved direct numerical simulation(DNs)models are described as an emerging technique to investigate turbulence-microphysics interactions at the most fundamental level by tracking individual particles and resolving the smallest turbulent eddies in turbulent *** challenges and future research directions are explored as well.

采用等径角挤压法回收Ti-6Al-4V合金切屑,并研究了回收样品和退火处理样品的微观结构和显微硬度。结果表明:在回收样品中,切屑之间的边界依然存在,而由于剧烈塑性变形,超细晶结构和较强的纤维织构得以形成。退火处理后,切屑边界部分消失,超细晶组织部分再结晶;而与此同时,退火处理样品展现出更宽泛的织构,再结晶晶粒并不存在择优取向。值得注意的是,退火处理样品的显微硬度较回收样品略有升高。

When a block of dense sandy soil moves downhill, the shear-induced soil dilatancy along the basal shear boundary produces a negative value of excess pore pressure that increases the basal frictional resistance. Dilatancy angle,Ψ, the degree to which the basal soil dilates due to the shear, normally evolves during slope failure. A study by other researchers shows that if Ψ is constant, the block of dense soil will remain stable(or unstable) sliding when the velocity-weakening rate of the basal friction coefficient of the block is small(or large) enough. Moreover, during unstable sliding processes, the block of dense soil exhibits "periodic" patterns of intermittent slipping. Here, we used a more efficient and accurate numerical scheme to revisit that study. We expanded their model by assuming Ψ evolves during slope failure. Consequently, we acquired completely different results. For instance, even though the velocity-weakening rate of the friction coefficient is fixed at the same smaller(or larger) value that those researchers use, the stable(or unstable) steady states of landslide they predict will inversely change to unstable(or stable) when Ψ decreases(or increases) with the increase of slide displacement to a value small(or large) enough. Particularly, in unstable processes, the soil block exhibits "aperiodic" styles of intermittent slipping, instead of "periodic". We found out that the stick states appearing later last longer(or shorter) in the case of decreasing(or increasing) Ψ. Moreover, because the basic states of landslides with impacts of dilatancy evolution are not steady nor periodic, traditional stability-analysis methods cannot be "directly" used to analyze the stability of such landslides. Here, we broke through this technical problem to a degree. We showed that combining a concept called "quasi-steady-state approximation" with a traditional stability-analysis technique can qualitatively predict the instability onset of the landslides.
