BACKGROUND Diffusion tensor imaging(DTI)-based navigation is unable to resolve crossing fibers or to determine with accuracy the fanning, origin, and termination of fibers. It is important to improve the accuracy of localizing white matter fibers for improved surgical approaches. We propose a solution to this problem using navigation based on track density(More)
The mechanism for the basal targeting of the Miranda (Mira) complex during the asymmetric division of Drosophila neuroblasts (NBs) is yet to be fully understood. We have identified conserved Phosphotyrosyl phosphatase activator (PTPA) as a novel mediator for the basal localization of the Mira complex in larval brain NBs. In mutant Ptpa NBs, Mira remains(More)
The objectives of this study were to investigate the energy input and output per hectare for sugar beet production in the northern Xinjiang Province, China, and to perform an economic analysis for farmers using drip-irrigation systems. Data were collected from 156 randomly selected sugar beet farms. The total energy input was 98,778.3 MJ ha−1.(More)
