A recent study reported the discovery of a plant-specific vacuolar trafficking route, i.e., a direct ER- to-vacuole route, through analysis of VHA-a3 subcellular targeting, a key component for the tonoplast V- ATPases. Our recent findings showed that VHA-a3 targets to the tonoplast through a Rab5-mediated but Rab7-independent pathway, shedding new lights on the unconventional vacuolar trafficking route in plant cells.展开更多

It is provided with multiple functions, such as laser scanning information management for goaf, cloud data de-noising optimization, construction, display and operation of three-dimensional model, model editing, profile generation, calculation of goaf volume and roof area, Boolean calculation among models and interaction with the third party soft ware. Concerning this system with a concise interface, plentiful data input/output interfaces, it is featured with high integration, simple and convenient operations of applications. According to practice, in addition to being well-adapted, this system is favorably reliable and stable.展开更多

The distribution and magnitude of tunnelling-induced initial excess pore water pressure have significant effects on the long-term consolidation settlement. A simple and reliable method for predicting the tunnel-induced initial excess pore water pressure calculation in soft clay is proposed. This method is based on the theory of elasticity and SKEMPTON's excess pore water pressure theory. Compared with the previously published field measurements and the finite-element modelling results, it is found that the suggested initial excess pore water pressure theory is in a good agreement with the measurements and the FE results. A series of parametric analyses are also carried out to investigate the influences of different factors on the distribution and magnitude of the initial excess pore water pressure in soft ground.展开更多

Although the country’s producer price index (PPI) scored new highs for months, international commodity prices fell substantially. But the Gross Domestic Product deflator, another important index which measures the change in prices of all new, domestically produced, final goods and services in an economy, indicates that the CPI’s slowdown has not yet brought any relief from inflation in the country. Will China soon see the end of inflation, or was it just a breather before another inflationary peak? The 21st Century Business Herald, a business newspaper published semiweekly, interviewed Huo Deming, an economics professor at the China Center for Economic Research at Peking University, for some insights.展开更多
