Ying Yang, Yanqi Zhao, Mingshi Wang, Hongqi Meng, more

Asia‐Pacific Journal of Chemical Engineering > 15 > S1 > n/a - n/a

As graphene is an emerging carbon nanomaterial, some studies have investigated the ecological effects of graphene‐based materials with generally focusing on physiological changes, enzyme activities, and oxidative stresses, but detailed mechanistic studies are actually lacking. Moreover, the results from previous studies were controversial in the context of ecological mechanisms, because material properties...

In solving intra-voxel fiber crossing problem in white matter fiber tracking, the classification of crossing and non-crossing regions seems essential and challenging. Although high C_p value is a usable indicator of intra-voxel orientational heterogeneity, only using this metric is not accurate enough to decide exactly whether fiber crossing occurs as the lack of an exact and recognized threshold....
