In this study, we examined whether Sprague-Dawley rats obtained from two different vendors, Harlan and Sasco, differ with respect to the types of alpha-2 adrenoceptors in the spinal cord that mediate antinociception. This hypothesis was tested using two alpha-2 adrenoceptor agonists, dexmedetomidine and ST-91, which are relatively selective for alpha-2A and alpha-2B adrenoceptors, respectively,...

This paper describes how evolutionary techniques of variation and selection can be used to create complex simulated structures, textures, and motions for use in computer graphics and animation . Interactive selection, based on visual perception of procedurally generated results, allows the user to direct simulated evolutions in preferred directions. Several examples using these methods have bee...

We report the detection of the H2 v=1-0 S(1) line at 2.122μm, from RNO91 in the L43 dark cloud, which is known to be a T Tauri star surrounded by a 1700AU disk structure (containing ices) and a weak outflow. The non-detection of the H2 v=2-1 S(1) line at 2.247μm suggests shock excitation rather than fluorescence. The emission is extended spatially up to 9 in the north-south direction. The line ...

This Practice Bulletin was developed by the ACOG Committee on Practice Bulletins— Gynecology with the assistance of Jeanne Sheffield, MD. The information is designed to aid practitioners in making decisions about appropriate obstetric and gynecologic care. These guidelines should not be construed as dictating an exclusive course of treatment or procedure. Variations in practice may be warranted...

M5tion estinlati~n is a very impQriant problem irl dynamic scene attatysis. Although it is easier to estimate motion ~ararneters frown 3D data than from 21) images, it is not trivial~ sauce the 3D data we have are almost always corrupted by noise, A comparative study on motion estimation from 3D line segments is presented. Two representations of Ike segments and two representations o~rotat~on a...
