Effector Detection in Social Networks
Guangmo, Tong, Shasha Li +2
In a social network, influence diffusion is the process of spreading innovations from user to user. An activation state identifies who are the active users who have adopted the tar…
Molecule-Induced Conformational Change in Boron Nitride Nanosheets with Enhanced Surface Adsorption
Qiran Cai, Aijun Du, Guoping Gao +11
Surface interaction is extremely important to both fundamental research and practical application. Physisorption can induce shape and structural distortion (i.e. conformational cha…
