This study employs a linear inversion algorithm to retrieve volume emission rates(VERs)of molecular O_(2) nightglow at 1.27μm,utilizing Limb-Viewed spectra obtained from the SCanning Imaging Absorption spectroMeter for Atmospheric for CHartographY(SCIAMACHY)payload on board the Envisat satellite.The retrieved results are compared with VERs data from the SABER payload on the Thermosphere Ionosphere Mesosphere Energetics and Dynamics(TIMED)satellite,exhibiting consistency.This will help to facilitate accurate revelation of spatial distribution and periodic variation in O_(2) nightglow.VERs are extracted monthly within the altitude range of 75-110 km from 2002 to 2012,yielding a climatology of spatial and temporal distributions.The meridional structure exhibits two maxima,at the equator and at 45°N.Between August and October,the VERs exhibit a meridional bimodal structure,with the weaker one above the equator and the stronger one above 45°N.In April,the VERs reach their annual maximum.Additionally,harmonic analysis reveals significant temporal variations on different scales.The emission shows characteristics of annual and semi-annual variation,and a non-linear long-term trend associated with solar cycle activity. 展开更多

In his quest for spiritual fulfillment, Thomas Stearns Eliot conducts a meticulous religious study which teaches him distinctive interpretations of human existence and their various functions that they are supposed to assume in the world. Eliot's personal attachment to religious knowledge and his reflections of religious studies inevitably manifest themselves in his literary works; be it his dramas or poems, mostly in the forms of philosophical and psychoanalytical analysis of his characters and the detected problems observed in their relationships. The Cocktail Party, a play starting off as a drawing-room comedy soon converts to a serious analysis of human psychology and the nature of human interactions. While engaging with these particular points, the play offers possibilities to discuss several religious allusions, though dealt with subtly. Integrated with religion, characters' attitudes towards a given situation and their final decision position them in their quest either in "hypothetical" enlightenment or in a "supposed" repetition of a vicious circle. The enforcing power behind the play is interestingly a psychiatrist, who adds dynamism and mystery to the plot and has a special task in making the play a drama of conversion. The inner conflicts of the characters which ultimately lead to a series of problems in their relationships are the main concern which causes the characters search for different solutions. Accordingly, they make their own choices to cease their inner struggles. This paper aims to explore the concept of conversion in Eliot's The Cocktail Party with references to the playwright's religious journey in his literary career. 展开更多

The spherical head model has been widely used in magnetoencephalography (MEG) as a simple forward model for calculating the external magnetic field producing by neural currents in a human brain. But this model may lead to an inaccurate result, even if the computation speed is fast. For more precise computation, realistic brain-shaped head model is used with the boundary element method (BME), but at greatly increased computational cost. When solving MEG inverse problem by using optimization methods, the forward problem must often be solved for thousands of possible source configurations. So if the brain-shaped head model is used in all iterative steps of optimization, it may be computationally infeasible for practical application. In this paper, we present a method about using compound head model in MEG inverse solution. In this method, first spherical head model is used for a rough estimation, then brain-shaped head model is adopted for more precise solution. Numerical simulation indicates that under the condition of same accuracy, the computation speed for the present method is about three times faster than a method using the brain-shaped head model at all iterations. 展开更多

The presence of DNA homologues corresponding to verc203 (vernalization-related cDNA clone) was investigated by molecular hybridization techniques. The genes were detected in 16 plant species that cover 12 subclasses of the Takhtajan system of angiosperms classification including diverse model species. The results of Southern blot analysis showed a low copy number of this gene existed in rice, wheat, barley and Arabidopsis. The hybridization result of PCR products demonstrated the conservation of the gene corresponding to ver203 in diverse plants. The phylogenetic tree of the ver203 gene in tested plants was supported by evolution relationship of species. The ver203 gene expressed in a vernalized plumule winter wheat, instead of the root. And the endosperm before the treatment was essential for the ver203 expression during vernalization in wheat. In Arabidopsis thaliana, the pattern of expression showed that the gene corresponding to ver203 was expressed at low temperature for 14 days. Gibberellin(GA3) may accelerate the expression of ver203 gene in Arabidopsis exposed to low temperature. However, it could not replace vernalization treatment to initiate the gene expression. 展开更多
