	abstract = {As social network services (SNS) are gaining popularity, establishing trust relationships among users in SNS is necessary for user interaction and decision making. However, the evaluation of global trust values (i.e. reputation) of users suffers from the curse of opinion divergence in the network. In this paper, we consider the scenario of opinion divergence within social networks, and propose a method to reach different global trust values between groups of users with controversial opinions in the network. We model the global trust opinion formation in discrete-time dynamics and introduce bipartite consensus as the approach to establish global trust in such circumstances. Such approach works upon the property of structural balance, and can be extended to more general situations where eventual positivity applies. Via our approach, non-trivial global trust can be reached within the network, which can guide users{\textquoteright} social behaviors, and support many SNS-based applications.},

	abstract = {Coordination control of multiple rigid bodies attracts much attention of researchers due to its wide applications. This~paper presents the pose synchronization problem of the moving rigid bodies whose dynamics is described by the group SE(3).~The case of undirected neighbor graphs with switching interconnection topologies is considered. We design a distributed control~law based on relative rotation matrices and relative positions between the neighboring rigid bodies, and show that the SE(3)~reaches pose synchronization if and only if the neighbor graphs are infinitely jointly connected, which relaxes the theoretical~results in the existing literature.},
