The aim of this study was to design a navigation system composed of a human-controlled leader vehicle and a follower vehicle. The follower vehicle automatically tracks the leader vehicle. With such a system, a human driver can control two vehicles efficiently in agricultural operations. The tracking system was developed for the leader and the follower vehicle, and control of the follower was pe...

We introduce and study incentive equilibria for multi-player meanpayoff games. Incentive equilibria generalise well-studied solution concepts such as Nash equilibria and leader equilibria (also known as Stackelberg equilibria). Recall that a strategy profile is a Nash equilibrium if no player can improve his payoff by changing his strategy unilaterally. In the setting of incentive and leader eq...

We study the problem of optimal leader selection in consensus networks under two performance measures (1) formation coherence when subject to additive perturbations, as quantified by the steady-state variance of the deviation from the desired trajectory, and (2) convergence rate to a consensus value. The objective is to identify the set of k leaders that optimizes the chosen performance measure...

Leader peptidase, an integral membrane protein of Escherichia coli, is made without a cleavable leader sequence. It has 323 amino acid residues and spans the plasma membrane with a small amino-terminal domain exposed to the cytoplasm and a large, carboxyl-terminal domain exposed to the periplasm. We have investigated which regions of leader peptidase are necessary for its assembly across the me...

RNA polymerase II of trypanosomes, early diverging eukaryotes, transcribes long polycistronic messages, which are not capped but are processed by trans-splicing and polyadenylation to form mature mRNAs. The same RNA polymerase II also transcribes the genes coding for the spliced leader RNA, which are capped, exported to the cytoplasm, processed, and reimported into the nucleus before they are u...

Distributed systems are the backbone of modern day computing services. A mobile ad hoc network (MANET) is a collection of mobile nodes that can communicate via message passing over wireless links. Communication takes place directly between nodes which are in transmission range of each other else communication is done through message relay. A MANET is different from existing distributed network ...

Cooperative control of a mobile robot with multiple communication sources is investigated. In the leader -follower framework, the robot is assumed as a follower and it follows the instructions of the leader. However, the communication sources are not only the leader but a lso its other associate following the leader. In this setup, the computation at the mobile robot need to churn the data it r...

This paper deals with a collision avoidance problem in leader-following formation navigation for multiple mobile robots. Because followers should move along a leader’s trajectory, we first try to avoid collisions by adjusting their velocities on the trajectory. This strategy causes delays of the followers from the leader, which is often problematic because we cannot predict how late the followe...

Leader-member exchange (LMX) differentiation, the extent to which the leader forms different quality exchange relationships with group members, is the fundamental premise of LMX theory. The present study tests whether, why, and when LMX differentiation increases group outcomes. More specifically, I suggest a dual perspective model of LMX differentiation and group effectiveness, which includes b...
