Polypyrimidine Tract-Binding Protein 1 (PTBP1) regulates CD4 T cell Activation independent of its role in proliferation

Autor: Bitha Narayanan, Diego Prado De Maio, James LaPorta, Yekaterina Voskoboynik, Rodrigo Matus-Nicodemos, Sean Summers, Usha Ganapathi, Anibal Valentin-Acevedo, Lori R. Covey

Our previous work found that the RNA binding protein polypyrimidine tract-binding protein (PTBP1) is critical for regulating multiple events in T cell activation including changes in proliferation, and expression of activation markers and cytokines.

Stochastic system controller synthesis for reachability specifications encoded by random sets

Autor: Claire J. Tomlin, John Lygeros, Sean Summers, Maryam Kamgarpour

Publikováno v: Automatica. 49:2906-2910

We consider a reach–avoid specification for a stochastic hybrid dynamical system defined as reaching a goal set at some finite time, while avoiding an unsafe set at all previous times. In contrast with earlier works which consider the target and av

Verification of discrete time stochastic hybrid systems: A stochastic reach-avoid decision problem

Autor: John Lygeros, Sean Summers

Publikováno v: Automatica. 46:1951-1961

We present a dynamic programming based solution to a probabilistic reach-avoid problem for a controlled discrete time stochastic hybrid system. We address two distinct interpretations of the reach-avoid problem via stochastic optimal control. In the

Fast explicit nonlinear model predictive control via multiresolution function approximation with guaranteed stability

Autor: John Lygeros, Davide M. Raimondo, Sean Summers, Manfred Morari, Colin N. Jones

Publikováno v: IFAC Proceedings Volumes. 43:533-538

In this paper an algorithm for nonlinear explicit model predictive control is introduced based on multiresolution function approximation that returns a low complexity approximate receding horizon control law built on a hierarchy of second order inter

A Probabilistic Reach-Avoid Problem for Controlled Discrete Time Stochastic Hybrid Systems

Autor: John Lygeros, Sean Summers

Publikováno v: ADHS

In this paper we present a dynamic programming based solution to a probabilistic reach-avoid problem for a controlled discrete time stochastic hybrid system. Similar to recent results related to the problem of probabilistic safety and stochastic targ

In silico feedback for in vivo regulation of a gene expression circuit

Autor: Mustafa Khammash, Ignacio A. Zuleta, David Pincus, John Lygeros, Sean Summers, Jacob Stewart-Ornstein, Hana El-Samad, Andreas Milias-Argeitis

Publikováno v: Nature Biotechnology

We show that difficulties in regulating cellular behavior with synthetic biological circuits may be circumvented using in silico feedback control. By tracking a circuit's output in Saccharomyces cerevisiae in real time, we precisely control its behav

Multi-Agent Autonomous Surveillance: A Framework Based on Stochastic Reachability and Hierarchical Task Allocation

Autor: John Lygeros, Nikolaos Kariotoglou, Davide M. Raimondo, Sean Summers

Publikováno v: Journal of Dynamic Systems, Measurement, and Control. 137

We develop and implement a framework to address autonomous surveillance problems with a collection of pan-tilt (PT) cameras. Using tools from stochastic reachability with random sets, we formulate the problems of target acquisition, target tracking,

A stochastic reachability approach to emergency building evacuation

Autor: Sean Summers, John Lygeros, Tony A. Wood

Publikováno v: CDC

In this paper we introduce a framework for real-time path planning for emergency building evacuation based on the theory of stochastic reachability with random sets. We consider the problem of a single human in a building escaping from a propagating
