These findings suggest that the contralateral hemisphere can compensate for the damaged cortex by remodeling neuronal activity. Thus, clinical treatments specifically targeted to the 'intact' hemisphere following stroke may provide a complimentary strategy for promoting recovery of functional deficits and for improving quality of life in stroke patients.
A series of physical and chemical changes, including the shrinkage and the phase transformation, will continuously take place during the sintering process of ceramic green body, which is important for designing a scientific and economic sintering schedule. The sintering behavior of two electrical porcelains and a structural tile were investigated using thermal analysis techniques. The dehydration, phase changes and densification of ceramic green body during sintering process were characterized by DSC-TG and thermal expansion curves. The sintering temperature range of ceramic green body was measured by thermal dilatometer with different heating rates. The sintering temperature Ts is linear to the logarithm of heating rate V. The results were compared with that measured by conventional refractoriness tester. The Ts is much more accurate to evaluate the sintering behavior of ceramic green body from the thermal analysis technique than that from the traditional method. The projected sintering schedule is very concordant to the experimental sintering results.
Locking mechanism of aviation aircraft is very important for perform mission. In order to avoid motion interference of locking mechanism efficiency and ensure mission completion and flight safety, its motion interference is analyzed based on its working theory. The spatial distribution of locking mechanism is designed in reason. The 3D solid assembly model of locking mechanism is constructed by using CATIA software. By the seamless interface program Sim-Designer between CATIA and ADAMS, dynamics simulation of locking mechanism system is realized in the circumstance of ADAMS. Its motion law is studied through simulation under the loading condition. The results show that there are good coincidence between simulation results and theoretical calculation datum. The method has more practicability and reasonability for the dynamics study of locking mechanism. And it offers theoretical basis for design and use of locking mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
