. Development of an engineered tissue for disc regeneration is still in its infancy due to the limited autologous healthy disc cell source from the patients. It is also challenging to mimic the complexity of micro-architecture in the native disc tissue that determine their unique structural properties. To date, simple tissue models that mimic the annulus fibrosus(AF) micro-environment......
(SPH) method. To mimic the constraints that the solid mold prescribes on the filling fluid, a composite treatment to the solid boundaries is elaborately designed. On solid boundary surfaces, boundary..., the Lennard-Jones force [7] can be applied to mimic arbitrary solid boundary due to its flexibility. However, its accuracy is not high, as in the regions near the boundary, the compact domain of SPH particle......
Studies on Expert System for Extraction of Rare Earths许禄,肖永辉,李德谦摘 要:<正> An expert system has been developed,using LISP,for extraction of rare earths.The expert system was de-signed to mimic the deduction of chemists for rare earth separation.The knowledge base consists mainly of threeparts:(1)the extractant solvents common use and the separations......
show that the injection of PLA as a molecular binder into the GO layer can effectively mimic the nano-structure, and enhance the intergranular force of the graphene molecules and the compatibility......
and limestone weight ratios of 0.5%,1.0%,and 1.5% were immersed in 5%(by weight)MgSO4 solution at 5 ℃ to mimic TSA.Appearance,mass,and compressive strength of the mortar samples were monitored and measured......
potential in wearable electronics.With tunable multilevel resistance states,flexible memristors could be used to mimic the bio-synapses for constructing high-efficient wearable neuromorphic computing......
transmission channel. Starting with a pair of antennas working in a human body mimic environment, the signal transmissions and attenuations were examined. The relationship between the signal attenuation......
