We propose a scheme for the teleportation of an arbitrary two-atom state by using two pairs of two-atom nonmaximally entangled states as the quantum channel in cavity QED. It is Shown that no matter whether the arbitrary two-atom pure state to be teleported is entangled or not, our teleportation scheme can always be probabilistically realized. The success prohability of teleportation is determined by the smaller coemcients of the two initially entangled atom pairs. 展开更多

Glaciers in the western Nyainqentanglha Range are an important source of water for social and economic development. Changes in their area were derived from two Chinese glacier inventories; one from the 197o 1:5o,ooo scale Chinese Topographic Maps series and the other from Landsat TM/ETM+ images acquired in 2009. Analyses also included boundaries from 2000 and 2014 Landsat TM/ETM+ images. A continuing and accelerating shrinkage of glaciers occurred here from 1970 to 2014, with glacier area decreasing by 244.38±29.48 km^2 (27.4%±3.3%) or 0.62%±0.08% a^-1. While this is consistent with a changing climate, local topographic parameters, such as altitude, slope, aspect and debris cover, are also important influences. Recession is manifested by a rise in the elevation of the glacier terminus. The shrinkage of glaciers with NE, N and NW orientations exceeded that of other aspects, and glaciers with SE and S orientations experienced less shrinkage. Changes in the average positive difference of glaciation (PDG) show that the western Nyainqentanglha Range has unfavorable conditions for glacier maintenance which is being exacerbated by a warming climate since 1970. 展开更多

Trace element(TE) and rare earth element(REE) contents in red soils from the Dongting Lake area of China were determined to understanding the provenance and weathering characteristics of the red soils.The results showed similar REE distribution patterns among red soils from the Dongting Lake area,Xiashu loess from Zhenjiang,loess and Pliocene red soil from the Loess Plateau.These patterns implied a similar provenance from dust-storms,except for red soil R5 which formed by bedrock weathering and had significant light REE(LREE) enrichment and heavy REE(HREE) depletion due to longer weathering periods and higher intensity of weathering.Trace element,especially the Rb/Sr and Li/Ba ratios,and REE,especially the LREE/HREE ratio and δEu could trace weathering intensity.Higher Rb/Sr,Li/Ba,and LREE/HREE ratios and negative Eu anomalies were present in the red soils from the Dongting Lake area.The weathering intensity was in the decreasing order of R5 in the Dongting Lake area > red soils from the Dongting Lake area(including reticulate red soil,weak reticulate red soil,and homogeneous red soil formed by dust storms) > Xiashu loess from Zhenjiang > loess-paleosol and Pliocene red soil from the Loess Plateau.Variations in the TE and REE contents of soil could be effectively used to study the provenance and the weathering intensity. 展开更多

This article involves the study of the psychic remnants commonly known as Archetypes in Sean O'Casey's play Juno and the Paycock. Archetypes are the images or patterns recurring again and again in literature through the ages. It also focuses on the minute difference between archetype and archetypal image as discussed by Jung with special reference to the characters and other images in the play beating relevance with the universal archetypes. This article also highlights the play as a connective link in the series of the different pieces of literature via the unique use of the psychic remnants. It emphasises on the different use of those remnants interwoven in the mosaic of the characters and plot of the play. 展开更多

Financial Statement Valuations in Italian Accounting Thought Between the 19th and the 20th Century: From "Exchange Value" to "Historical Cost"

The main subject of this paper is the theory of financial statement valuations observed in its historical development. More notably, regarding the subject, the research is concerned with some theoretical concepts developed by the Italian doctrine in a very specific age, namely, between the 19th and the 20th century, which in fact, devoid of any accounting regulation. This paper analyzes in particular the shift from the exchange value rule to the historical cost method and tries to explain the reasons of such a development. In the second half of the 19th century, some of the best Italian scholars, who were faced with the need to properly develop the problem of accounting valuations, thought that it was appropriate to rely on concepts that belonged to similar sciences, such as economics and real estate appraisal, by blindly borrowing the theory of value from the former and the theory of valuations from the latter. During that age, everything hinged around the concept of exchange value. At the dawn of the 20th century, the Italian accounting doctrine began to wonder about a subject that was crucial to the financial statement theory: the informative purposes underlying the financial statements. At the same time, the first principle took shape, which might be called as the "finalistic principle of value". It is still the basis of the theory of financial accounting measurements, for which different evaluative criteria must be applied to different informative purposes. Thus, an alternative criterion to that of the exchange value makes its appearance on the scene of the accounting valuations, notably the historical cost. The introduction of the historical cost criteria and above all the relinquishment of the combination of the "economic cost" in favor of that of the "manufacturing cost" allow the Italian accounting to get rid of the theories of economics and real estate appraisal, thus, becoming independent regarding the financial statement valuations. 展开更多

The films Catch-22 (1970) and The English Patient (1996) are based on literary novels, and set in the specific time and place of World War II Italy. Each work uses the topic of the war to raise the issues of identity and loyalty that loom large during wartime, when nations place huge demands on their people. Both works explore these issues as relevant to their own time. In the 1960s, Catch-22 elevates loyalty to self as a value and challenges the dehumanizing conformity demanded by the bureaucratic states of the postwar world. Twenty-six years later, The English Patient honors loyalty to people rather than to nations. Both movies end in hope, with Yossarian's escape in Catch-22, and the end to the European war in The English Patient. This paper argues that Michael Ondaatje's novel, The English Patient, goes beyond the issues of identity and loyalty and the hopeful Hollywood ending as seen in the movies. By giving Kip's and Hana's points of view, which were not shown in the film--the view of a brown man in a world controlled by whites and of a woman who understands the horrors of the atomic bomb--Ondaatje offers the possibilities of a new sense of identity and loyalty, one more in tune with issues of a post-colonial 21 st century world 展开更多

Multi-variate analysis (PCA) of all the data was undertaken. The first principal component was positively correlated with chlorides, sulphites, hardness, and negatively correlated with altitude. The second principal component was positively correlated with DO and pH. Results showed that 4 groups of springs could be distinguished on the basis of environmental variables. A small number of springs did not group with the geographically more proximal springs but with another group due to a greater degree of affinity on the basis of the hydrochemical variables. 展开更多

In consideration of the confused debates about the value of nominalization, this paper tries to explore the original generation of nominalization and analyze its use in poetry. This paper attempts to explore the generation of nominalization from a comprehensive point of view, to distinguish between "primary nominalization" and "ideological nominalization", to trace the root of primary nominalization, and to analyze the use of primary nominalization in poetry. Based on these analyses, this paper points out that primary nominalization in poetry is more consonant with the Green grammar, with the undivided, holistic ecological worldview and has ecological significance. However, the ideological nominalization in some other nonliterary formal style is an obstacle to the solution to environment problem, and so we should understand the function of nominalization with its contexts and pay more attention to poetic language. 展开更多

Bringing the aspect of "gender" into translation studies, feminism gave fresh impetus to the "Cultural Turn" for translation studies in 1990s. Feminist translation theory puts forward its viewpoints on the role of gender and approves of translators' gender role in the interpretation of the original text. It seems that gender is of no more importance than other factors, such as nationality, class, and ideology of translators. Translation and women have been long associated with each other for they both occupy peripheral positions. The conventional view holding sway is that a translation is considered a secondary work dependent on, and subservient to, the original text, just as women are assigned dependent functions under patriarchal power. Unsatisfied with the notion that translator, translation and women are all relegated to the inferior class, feminist translators do their utmost to cast away the conventional sexism ideas in translation studies and social ideology. The core of feminist translation theory is: "identify and critique the tangle of concepts which relegates both women and translation to the bottom of the social and literary ladder" (Simon 1996:1). In order to realize the dream to overthrow patriarchal domination and make themselves visible, feminist translators seek to emphasize their identity and ideological stance in the translation project. Feminist translators are no longer invisible. They have the right to revise, manipulate and occupy the source text. Feminist translation is nothing but the translators' creative treason from the perspective of feminism. The thesis first systematically summarizes the present feminist translation theories, followed by a detailed analysis of some gender-related translation issues, especially the relationship between language and gender. After the analysis of some cases from the feminist translators, different translation approaches adopted are explored to show the peculiar characteristics of feminist translation. 展开更多

Objective: The aim of this study was to investigate the expressions of CD147 and CK19 in hepatocellular car- cinoma (HCC) and their clinical significance. Methods: The expressions of CD147 and CK19 were determined by tissue microarray and immunohistochemistry (IHC) in 272 cases of HCC and 81 cases of adjacent tumorous tissue. Results: The positive expression of CD147 in HCC and adjacent tumorous tissue was 73.53% (200/272) and 13.58% (11/81) with signifi- cant difference (P < 0.05). The positive expression of CK19 in HCC and adjacent tumorous tissue was 14.34% (39/272) and 0 (0/81) with significant difference (P < 0.05). The positive expression of CD147 were closely correlated to the histological grade, clinical stage, tumor-free survival, diameter of tumor and embolus of cancer in aqueduct or portal vein; but not to the patients' sex, age, liver cirrhosis, AFP level, infection of HBV, lymph node metastasis, number of tumor, invasion liver involucrum and the micro-satellites (P > 0.05). The expression of CK19 in HCC were closely correlate to the tumor-free survival, histological grade, diameter of tumor, liver cirrhosis, micro-satellites, lymph node metastasis and clinical stage; but not to patients' sex, age, number of tumor, invasion liver involucrum, AFP level, infection of HBV and embolus of cancer in aqueduct or portal vein (P > 0.05). Among the patients of positive expression of CD147, the median replacing time and overall survival were 13 and 24 months, lower than 48 and 60 months in the patients of negative expression (P < 0.05). Among the patients of positive expression of CK19, the median replacing time and overall survival were 7 and 13 months, lower than 31 and 42 months in the patients of negative expression (P < 0.05). The expression of CD147 had no correlation with the expression of CK19 (r = 0.061, P = 0.317). Conclusion: The positive of CD147 and CK19 closely correlate with the clinical prognosis of HCC, it may indicate poor prognosis of HCC. 展开更多

AIM: To explore the relationship between DNA methyltransferase 1 (DNMT1) and hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) and its biological significance in primary HCC. METHODS: We carried out an immunohistochemical examination of DNMT1 in both HCC and paired nonneoplastic liver tissues from Chinese subjects. DNMT1 mRNA was further examined in HCC cell lines by real-time PCR. We inhibited DNMT1 using siRNA and detected the effect of depletion of DNMT1 on cell proliferation ability and cell apoptosis in the HCC celt line SMMC-7721. RESULTS: DNMT1 protein expression was increased in HCCs compared to histologically normal nonneoplastic liver tissues and the incidence of DNMT1 immunoreactivity in HCCs correlated significantly with poor tumor differentiation (P = 0.014). There were more cases with DNMT1 overexpression in HCC with HBV (42.85%) than in HCC without HBV (28.57%). However, no significant difference in DNMT1 expression was found in HBV-positive and HBV-negative cases in the Chinese HCC group. There was a trend that DNMT1 RNA expression increased more in HCC cell lines than in pericarcinoma cell lines and normal liver cell lines. In addition, we inhibited DNMT1 using siRNA in the SMMC-7721 HCC cell line and found depletion of DNMT1 suppressed cells growth independent of expression of proliferating cell nuclear antigen (PCNA), even in HCC cell lines where DNMT1 was stably decreased. CONCLUSION: The findings implied that DNMT1 plays a key role in HBV-retated hepatocellular tumorigenesis. Depletion of DNMT1 mediates growth suppression in SMMC-7721 cells. 展开更多

By using petrological,isotope chronological,and geochemical methods,the authors studied the volcanic rocks in the studied area,mainly including dacites and trachytes. The results show that they formed during the late Early Cretaceous. Geochemically,the volcanic rocks are relatively enriched in large-ion lithophile elements( Rb,K,and Th) and depleted in high field strength elements( Nb,Ta,and Ti),and rich in light rare earth elements,and depleted in heavy rare earth elements. The fact indicates that the main body of the volcanic rocks in the Qushenla Formation was derived from the partial melting of lower crust. The lithological assemblages are characterized by continental high-K calc-alkaline and shoshonitic series,suggesting that the southward-subducting oceanic slab in southern Bangong Lake had break off and that the Bangong Lake-Nujiang Ocean had closed before 107 Ma. The main dynamic mechanisms for the genesis of this set of intermediate-acidic volcanic rocks were upwelling of the asthenosphere and partial melting of the lower crust caused by slab break-off. 展开更多
