We consider resonant absorption in a spectral line in the outflowing plasma within several tens of Schwarzschild radii from a compact object. We take into account both Doppler and gravitational shifting effects and re-formulate the theory of P-Cygni profiles in these new circumstances. It is found that a spectral line may have multiple absorption and emission components depending on how far the...

This paper attempts to answer what should be taken into consideration to authorize persuasive multimedia contents, especially in the ad domain. Being persuasive is the essential property of ads, as simply delivering information may not be sufficient to persuade those who are exposed to them. On authorizing persuasive multimedia contents, much has been discussed from a technological and technica...

Exterior algebraic shifting and symmetric algebraic shifting of bipartite graphs and chordal graphs are studied in the present paper. keywords : Algebraic shifting, chordal graph.

Attention shifting refers to one core component of executive functions, a set of higher-order cognitive processes that predict different aspects of academic achievement. To date, few studies have investigated the role of attention shifting in orthographic competencies during middle childhood and early adolescence. In the present study, 69 first-grade, 121 third-grade, and 85 eighth-grade studen...

In 1925, a game called ‘exquisite corpse’ was invented by a group of surrealists to harness the random power of imagination through collaboration. Working either with words or drawings, an exquisite corpse was begun by one member of the group, who then folded the paper so that his or her contribution was obscured and then passed it to the next member. The game (named after one of their first re...
