0 the curved shape made when something long and thin, such as a piece of string, bends until one part of it nearly touches or crosses another part of it -- 圓圈，環形
1 to make a loop or curve -- 纏繞；彎曲
Analysis of one patient's flow-volume loops was consistent with grunting and the subject was excluded from the study.
The only condition is that all nucleotides in that segment have to be used - for instance, and for the hairpin loops.
Unfortunately, such positive feedback loops may form a vicious cycle leading to progressive problems for some children.
With the use of the controlled delivery system, the number of loops on the pulmonary side can be minimized to less than one.
Similarly, the importance of feedback loops in socioeconomic systems is widely recognized.
Endogenizing other feedback loops not included in this paper, for example, the pollution impact on production, could have similar effects.
Let us relate these plots to the geometry of the integration loops.
Conditioning on no loops or multiple edges, we obtain the permutation graph model.
