Twenty cases(9.4%) had columnar islands alone. Two hundred and eight cases(97.7%) lacked the circumferential CLE component(C0Mx). Columnar islands were found in 70 cases(32.9%), of which 20 cases(9.4%) had columnar islands alone.CONCLUSION:In regions where most CLE patients display short or ultrashort tongue-like appearance, more detailed descriptions of CLE's in < 1.0 cm lengths and columnar islands, as well as avoidance of repeating the prefix "C0" need to be considered in parallel with the widespread application of the Prague system in South Korea.展开更多

It was a year in the United States that witnessed the assassinations of Martin Luther King, Jr., in April and of Robert Kennedy in June, ongoing student protests against the war in Vietnam, the Tet offensive and the My Lai Massacre, the upheaval of the Democratic National Convention in Chicago in August, as well as the civil rights movement and the initial manifestations of the women＇s movement and the environmental movement. Moreover, beyond the borders of the United States, student demonstrations against government oppression occurred in Warsaw in March, in Paris in May, and in Mexico City in September tied to the Olympic Games that year in Mexico. The researchers also witnessed the joy of the Prague Spring from January until the subsequent Soviet-led Warsaw Pact invasion of Czechoslovakia at the end of August. Richard M. Nixon was elected president of the United States in November, the counterrevolution of conservatism, if you will, that may have run its 40-year course with the administration of George W. Bush and the election on November 4 2008 of Democratic Illinois Senator Barack Obama.展开更多

And they had been in a much more important position of the linguistic history. Some distinguished scholars, such as V. Mathesius, Jakobson, Trubetzkoy, played a landmark role to the development of linguistics during that periods, leaving a rich heritage on ideas to the descendants. And even their influences went beyond the scope of linguistics. The dynamic study to many aspects of linguistics made them win a permanent position. This paper is just from the heuristic function about ideas on the Prague School, trying to talk about something a little bit.展开更多

Such complex structured systems are susceptible to external interferences and, thus, cannot meet the increasingly strict monitoring needs of a complex air-conducting pipeline system of an aircraft. In view of this point, this paper studies an alternative sensor system based on a dense array fiber grating. To obtain a compact and light-weight airborne signal processing system, a field programmable gate array is used as the main control core that controls the output of the light source. The functions of pulse modulation, analog-to-digital conversion,data buffering and transmission are integrated into a single system, while the linear sensing monitoring is obtained by detecting the time-division and wavelength-division wavelength drift signals of the fiber Bragg grating array. Our experiments show that the spatial resolution of the linear sensing system approaches 5 cm, the temperature measurement accuracy reaches 2 ℃, the temperature measurement range is between 0–250 ℃, and the response time is within 4 s. Compared with the existing electrical monitoring systems, various monitoring indicators have been greatly improved and have broad application prospects.展开更多

These images of reversible portraits of genre scenes, caricatural conceits, and visual puns are seen in The Cook or The Chef reversed as The Bowl of Meats of 1570 at the Nationalmuseum, Stockholm;The Vegetable Gardener reversed as The Bowl of Vegetables of 1590 at the Museo Civico “Ala Ponzone”, Cremona;and Il Frutaio, The Fruit Vendor reversed as The Basket of Fruits of 1591, at the French & Company Gallery in New York. In his imagery, Arcimboldo focuses on the paradoxical meaning of objects,“what if?” adding a sense of ambiguity and mystery to his art. Is Arcimboldo teasing the viewer with a Mannerist flare, or is he composing or implying another type of intellectual conceit? Ultimately, Arcimboldo invents a new type of genre: the emblematic humorous portrait.展开更多
