For given n, assume that we need to draw out randomly n1 points from n points in N(xk*)⧹{xk*}. Set I1=[n/n1], where [a] denotes the integer part of the real number a. If n/n1 is an integer, then we can partition the set N={1,…,n} into n1 disjoint subsets and ...

The Ni-Co nanowires filled MWCNTs effectively hindered the agglomeration and leach out of Ni nanowires from the MWCNTs, which greatly preserved the intrinsic electrical conductivity of the composite. The mechanism involved in the elec- trooxidation of glucose at MWCNT/Ni-Co nanostructures is ...

Only grassland was selected to estimate the AGB, and other land covers were masked out. In recent years, the degradation of grasslands has become an increasingly serious problem, which is directly caused by the influence of human activities, such as overgrazing [36,37]. The field campaign was...
