Spontaneous bursting activity in cultured neuronal networks is initiated by leader neurons, which constitute a small subset of first-to-fire neurons forming a sub-network that recruits follower neurons into the burst. While the existence and stability of leader neurons is well established, the influence of stimulation on the leader-follower dynamics is not sufficiently understood. By combining ...

This paper presents an analysis of the synchronization and consensus problems of networked manipulators operating on an underactuated dynamic platform in the presence of communication delays. The proposed formulation does not require detailed information about the system model. A theoretical formulation based on input-output maps of functional differential equations shows that the control syste...

This paper presents a motion control strategy for a rigid and constraint consistent formation that can be modeled by a directed graph whose each vertex represents individual agent kinematics and each of directed edges represents distance constraints maintained by an agent, called follower, to its neighbouring agents. A rigid and constraint consistent graph is called persistent graph. A persiste...

People exhibit peer-induced fairness concerns when they look to their peers as a reference to evaluate their endowments. We analyze two independent ultimatum games played sequentially by a leader and two followers. With peer-induced fairness, the second follower is averse to receiving less than the first follower. Using laboratory experimental data, we estimate that peer-induced fairness betwee...

This article presents a simple model to determine the location strategies of two retail firms planning to open a number of stores in a geographical market. Firms try to maximize their profit under a leader-follower type competition in which the number of stores is made endogenous by the introduction of fixed costs. A novel methodology is developed, in which firms’ strategies are defined in term...

We propose that a leadership identity is coconstructed in organizations when individuals claim and grant leader and follower identities in their social interactions. Through this claiming-granting process, individuals internalize an identity as leader or follower, and those identities become relationally recognized through reciprocal role adoption and collectively endorsed within the organizati...

This paper studies a cooperative encirclement interception guidance law against maneuvering target that utilizes leader–follower control scheme. The design is decoupled into two parts. In the line-of-sight (LOS) direction, fixed-time distributed disturbance observer presented to estimate of target. Based on proposed observer, designed for followers guarantee each follower’s total flight time ac...
