According to the MCF, expressions of the mean irradiance and average speckle size at the receiver were obtained. The analysis indicated that the mean intensity is closely related to the ratio of root mean square(rms) height to the lateral correlation length. In addition, the speckle size at the receiver is associated with turbulence strength, propagation distance and roughness of the target. The results can be reduced to the result of a Gaussian beam illuminating rough target and scattering from a target in free space.展开更多

Exam grades in mathematics, social studies,and Turkish was compared between the first and the second terms. Forty children were included in thestudy,with 22 male and 18 female,and their average age was 11.1 years. These patients were undergoing acupuncture treatment for attention deficit-hyperactivity disorder(ADHD), enuresis nocturna, migraine, obesity, atopic dermatitis, alopecia areata, and Tourette's syndrome. Treatments were done at the beginning of the second term. Four of the 25 patients with ADHD had borderline intelligence quotients.The report cards of all 40 patients were examined, and their grades in the first and these condschool term were compared.RESULTS: There was a statistically significant increase in the grades obtained in mathematics, social studies, and Turkish(P<0.005) by the students from the first to the second school term. When 4 ADHD patients with borderline deficiency in intelligence were excluded, and the grades among the 21 patients with ADHD were compared for both terms, there was also a statistically significant increase in mathematics, social studies, and Turkish grades(P<0.05).CONCLUSION: Acupuncture contributed to the academic success of the children who under went acupuncture treatment for their primary symptoms.展开更多
