Using a Hash function which uses time as the key,both mobile sinks and sensors can determine the same Hash area. The sensors can send the information about the events that they monitor to the Hash area and the mobile sinks need only to query that area instead of flooding among the whole network,and thus much energy can be saved. In addition,the location of the Hash area changes over time so as to balance the energy consumption in the whole network. Theoretical analysis shows that the proposed protocol can be energy-efficient and simulation studies further show that when there are 5 sources and 5 sinks in the network,it can save at least 50% energy compared with the existing two-tier data dissemination(TTDD) protocol,especially in large-scale wireless sensor networks.展开更多

The Renditions Series serves as a classical case of providing aneffective model of “literature’s overseas distribution”. The successful experience of itstranslating-cum-disseminating model can be concluded as follows: all the translatorsare from China and overseas with cross-cultural background; the selection oftranslation is stylistically far-ranging among the Mainland, Taiwan and Hong Kong,and feminine literature in modern China is highly valued; translating method aims atconvoying the original literary aesthetics, and disseminating channels are manifold;the foreign recipients are common and professional readers; the eminent effects canbe proved by its considerable sales, library collections and acceptance in the targetcountries and regions. From the successful model of translation of Renditions Series,five implications can be made out for the modern Chinese literature’s “Going-global”:domestic and overseas translators cooperate well with all-round cultural identities; theselection holds onto diversification and literary character; various spreading channelsshould be broadened; target readers should be accurately located and continuouslywidened; translating and disseminating effects can be focused on and analyzed, so asto adjust and improve the corresponding sections in the model.展开更多

The chemical analysis result shows that the lead and zinc oxide content exceeding the minimum industrial grade and iron ore, total iron content reaches a minimum industrial grade and associated with gold and silver; The mineralogical analysis result shows that lead and zinc mineral composition and configuration are very complexity. The zinc minerals and zinciferous minerals are sphalerite, hemimorphite, Smithsonite, Hydrozincite, zinc chlorite, limonite, zinc dolomite and zincocalcite; lead minerals and plumbiferous minerals are mainly galena, cerussite, anglesite, limonite and Coronadite; The minerals disseminated grain size are very fine and mineral dissemination characteristics are very complex ; expected theoretical recoveries for lead and zinc were 72% and 67% respectively. The results of this study provide basic data and theoretical basis for ore dressing.展开更多

There aregenerally tumor infiltrating T lymphocytes in situ oftumor, but most of which are inactive, one of the majorreasons of such Inactivation is that T lymphocytes areexposured to an antigen-specific TCR signal in theabsence of antigen-nonspecific or co-stimulatory signal.The co-stimulatory factors, B7-l and B7-2 on the surfaceof antigen presenting cells provide a key signal for thegeneration of T cell immunity.
