Because Broca＇s area and Wernicke＇s area in the brain are connected by the arcuate fasciculus, understanding the anatomical location and morphometry of the arcuate fasciculus can help in the treatment of patients with aphasia. We measured the horizontal and vertical curvature ranges of the arcuate fasciculus in both hemispheres in 12 healthy subjects using diffusion tensor tractography. In the right hemisphere, the direct curvature range and indirect curvature range values of the arcuate fasciculus horizontal part were 121.13 ± 5.89 and 25.99 ± 3.01 degrees, respectively, and in the left hemisphere, the values were 121.83 ± 5.33 and 27.40 ± 2.96 degrees, respectively. In the right hemisphere, the direct curvature range and indirect curvature range values of the arcuate fasciculus vertical part were 43.97 ± 7.98 and 30.15 ± 3.82 degrees, respectively, and in the left hemisphere, the values were 39.39 ± 4.42 and 24.08 ± 4.34 degrees, respectively. We believe that the measured curvature ranges are important data for localization and quantitative assessment of specific neuronal pathways in patients presenting with arcuate fasciculus abnormalities.

A soft-sensing model for key parameters of process industry driven by both qualitative and quantitative information is proposed,which aims at the characteristics that key parameters in process industry can not be measured online,multi-sub-processes,qualitative information and quantitative information *** the sub-processes with quantitative information as the main part,a small amount of qualitative information in the process is quantified,and the sub-process model is established by data-based modeling method;for the sub-processes with qualitative information as the main part,a small amount of quantitative information in the process is quantified,and the sub-process model is established by knowledge-based modeling *** soft sensing results of the final key parameters are obtained by using the model *** on the hydrometallurgical process,a hybrid soft sensor model based on case-based reasoning（CBR） and RBF network in series is *** simulation results show that the model is effective.
