SUMMARY:Design of Robust Interdependent Networks by Introducing Protective 
	Nodes
DESCRIPTION:Featuring Xin Yuan\n\nPart of the Preliminary Oral Exam.\n\nExa
	mining Committee:  Stanley\, Skocpol\, Erramilli\, Black\n\nAbstract:\n\nMo
	dern complex systems are generally interdependent and have been demonstrate
	d to be subject to cascading failures and catastrophic abrupt collapse. Her
	e\, we study a system of interdependent networks A and B with the introduct
	ion of a fraction of protective nodes in each network to strengthen the sys
	tem against random node failures in both networks. With this strategy\, usi
	ng percolation theory\, we find that for fully interdependent ER networks\,
	 if the protective nodes exceed a critical fraction of 0.1756\, which does 
	not depend on the mean degree\, the system would not undergo a percolation 
	transition against random node failures. Our results show that this strateg
	y can help design resilient interdependent complex systems.\n\n\n![XinYuan]
