Because they are fascinated by mathematics , logic , and science and have taken on the rational madness of their scientific confreres , we read much these days about information theory and its relation to the psychology and composition of music ; about statistical probabilities , stochastics , and the markoff chain and their compositional possibilities , about group and set theory as applied to serial music ; about aleatory and indeterminacy and entropy

Feb. 10, 2003 In a small randomized study, patients who underwent laparoscopic anterior lumbar interbody fusion spent less time in the hospital and returned to work sooner than patients who underwent open ALIF procedures, according to results reported here at the 70th annual meeting of the American Academy of Orthopaedic Surgeons.

Feb。 10， 2003 -在第70届美国矫形外科学会年会的报告中，有一项小型随机试验的结果显示，以腹腔镜来进行前位腰椎椎体间融合术，患者花在住院与恢复工作能力的时间比传统开放式ALIF手术来得短。

METHODS: Models of ALIF, PLIF and TLIF were simulated. After examination as normal group, the samples were randomly divided into three groups (n=5). Besides anterior, posterior and transforaminal lumbar interbody fusion include anterior, bilateral pedicle screw fixation was performed.
