By collecting personalized data, firms and political campaigners (senders) are able to better tailor their communication to the preferences and orientations of individual consumers and voters (receivers). This paper characterizes equilibrium persuasion through selective disclosure of the information that senders acquire about the preferences of receivers. We derive positive and normative implic...

For regulating the dynamic nonholonomic mobile cart with parameter uncertainties, a time-varying robust control law is derived to yield globally exponential convergence of carts position and orientation to the desired set point. The controller design relies on converting the carts dynamics to an advantageous form, and the robust linear feedback control laws steer the carts position and orientat...

In this paper, we propose a novel distributed formation control strategy, which is based on the measurements of relative position of neighbors, with global orientation estimation in 3-dimensional space. Since agents do not share a common reference frame, orientations of the local reference frame are not aligned with each other. Under the orientation estimation law, a rotation matrix that identi...

Wolff's law of trajectorial orientation proposes that trabecular struts align with the orientation of dominant compressive loads within a joint. Although widely considered in skeletal biology, Wolff's law has never been experimentally tested while controlling for ontogenetic stage, activity level, and species differences, all factors that may affect trabecular bone growth. Here we report an exp...

This study addressed the question of how the three-dimensional (3-D) control strategy for the upper arm depends on what the forearm is doing. Subjects were instructed to point a laser-attached in line with the upper arm-toward various visual targets, such that two-dimensional (2-D) pointing directions of the upper arm were held constant across different tasks. For each such task, subjects maint...
