Given a unilateral forward shift S acting on a complex,separable,infinite dimensional Hilbert space H,an asymptotically S-Toeplitz operator is a bounded linear operator T on H satisfying that{S^(*n)T S^n}is convergent with respect to one of the topologies commonly used in the algebra of bounded linear operators on *** this paper,we study the asymptotic T_u-Toeplitzness of weighted composition operators on the Hardy space H^2,where u is a nonconstant inner function.

In view of the study of finance and economics information, we research on the real-time financial news posted on the authority sites in the world's major advanced economies. Analyzing the massive financial news of different information sources and language origins, we come up with a basic theory model and its algorithm on financial news, which is capable of intelligent collection, quick access, deduplication, correction and integration with financial news' backgrounds. Furthermore, we can find out connections between financial news and readers' interest. So we can achieve a real-time and on-demand financial news feed, as well as provide a theoretical basis and verification of the scientific problems on real-time processing of massive information. Finally, the simulation experiment shows that the multilingual financial news matching technology can give more help to distinguish the similar financial news in different languages than the traditional method.

The English Middle Construction (EMC), as a piculiar syntactic structure, shares its semantic features, but diversifies in its syntactic configuration compared with other languages. This paper tries to have a contrast study of the Middle Construcitons between English and Chinese and find the two languages share the same semantic features that the incompatibility between the semantic quantitatives (SQs) of the Adverb (Adjunct in the syntactic term) and the SQs of the Verb denoted by the predicate of MC leads to the deactivization of the predicate by means of the Adjunct, functioning as a quantitative device, assign delimitation to the predicate, hence ensures the grammaticality of the construction. But syntatically, we agree that the NP Movement Approach accounts for the formation of EMC, while we argue in Chinese it is the verb raising that results in the MC. This paper first represents the structural representation of the English Middle Construction; then the structural analysis is elaborated in comparison with that in Chinese, based on the previous studies; and finally the motivations of the Ecs in the perspective of syntactic and semantic functions are explored and hence a new hypothesis is raised to probe the similar construction in Chinese.

A bias in clear-sky conditions that will be involved in estimating particulate matter （PM） concentration from aerosol optical depth （AOD） was examined using PM10 from two Aerosol Robotic Network sites in Korea. The study periods were between 2004 and 2007 at Anmyon and between 2003 and 2011 at Gosan, when both PM10 and AOD were available. Mean PM10 when AOD was available （PMAOD） was higher than that from all PM10 data （PMall） by 5.1 and 9.9 μg/m3 at Anmyon and Gosan, which accounted for 11% and 26% of PMall, respectively. Because of a difference between mean PM10 under daytime clear-sky conditions （PMclear） and PMAoD, the variations in APM10, the difference of PMan from PMdear rather than from PMAoD, were investigated. Although monthly variations in APMlo at the two sites were different, they were positively correlated to those in AT, similarly defined as APM10 except for temperature, at both sites. APM10 at Anmyon decreased to a negative value in January due to an influence of the Siberian continental high-pressure system while APM10 at Gosan was high in winter due to an effect of photochemical production at higher temperatures than at Anmyon.

In ambiguity application,it is discovered that the English tragedies' cognitive modes have experienced such an evolution that in Shakespeare's tragedies,the addressor and his addressee are separated and ambiguity application is wholly practiced with definite right standard context,though too late in disambiguation,in Shaw's,the addressor and his addressee are adhesive and the application wholly but with wrong standard context in disambiguation,and in O'Neill's,the addressor and his addressee are identical and disambiguation could not be done without standard *** different modes have revealed the cognitive causal process of the tragedies and the evolution the modes bring about indicates the tragedy is deepening in the English tragedies,from which the cognitive connotation of the evolution is further illuminated.

Modulation of the Schottky barrier heights was successfully demonstrated for WNx/p-Ge and WNx/n-Ge contacts by increasing the nitrogen component in the WNx films. The WN0.38/p-Ge contact exhibits rectifying characteristic and an apparent Schottky barrier of 0.49 eV while the WN0.38/n-Ge Schottky contact exhibits quasi-Ohmic current–voltage characteristics. Dipoles formed at the contact interface by the difference of the Pauling electronegativities of Ge and N are confirmed to alleviate the Fermi-level pinning effect.

Architecture makes up an important part of traditional Chinese culture. Rich in artistic language and condensed in ethic culture,the delicate brick- carvings of the Ming and Qing Dynasties demonstrate the social customs and peoples’ aspiration for life and imply rich Chinese traditional culture. By using the rhetorical methods of homonym,symbolizing,message and compare etc.,the brick-carvings of Bozhou Gorgeous Dramatic Stage express an optimistic attitude tow ard life and the perennial life spirit of the Chinese people. And the simplicity and freshness of ancient brick carvings reflects the harmony of Chinese culture and its aesthetic ethic.

The thesis analyses the narrative style of graphic novel Safe Area Gorazde,written by American Graphic novelist Joe Sacco,from six points,and they are first person narrative,multiple- level narrative,techniques of presenting motion,various speech balloons,visualized sound and page layout. The graphic novel combined images and text perfectly to narrate the cruelty of the Bosnian War and the sufferings of people in "the safe zone".
