Verification of Liveness Properties in Distributed Systems
This paper presents liveness properties that need to be preserved by Event-B models of distributed systems. Event-B is a formal technique for development of models of distributed systems related via refinement. In this paper we outline how enabledness preservation and non-divergence are related to the liveness properties of the B models of the distributed systems. We address the liveness issues related to our model of distributed transactions and outline the construction of proof obligations that need to be discharged to ensure liveness

Supporting data for Effects of Segment Length Asymmetry in Ternary Diblock Co-polymer-Homopolymer Mixtures
This data set contains data files and scripts to generate results reported in "Effects of Segment Length Asymmetry in Ternary Diblock Copolymer−Homopolymer Mixtures" by Yadav et al. Self-consistent field theory was used to study the effect of asymmetry between A and B statistical segment lengths on interfacial properties and phase behavior in ternary mixtures of AB diblock co-polymers, A homopolymers, and B homopolymers. We consider systems with volumetrically symmetric homopolymers and co-polymer, in which a difference between A and B statistical segment length is the only source of asymmetry between A and B monomers. The sign of the spontaneous curvature of monolayer interfaces between A- and B-rich homopolymer domains is shown to depend on the ratio of co-polymer to homopolymer chain lengths: Interfaces preferentially curve toward the component with a higher statistical segment length when the homopolymer lengths are greater than or comparable to the co- polymer length (as also found in diblock co-polymer melts) but curve away from this component when the homopolymers are much shorter than the co-polymer.National Science Foundation through the University of Minnesota MRSEC under Award Number DMR-1420013Yadav, Mridul; Morse, David C; Bates, Frank S.

Srdja Popović in conversation with Yogendra Yadav: “Every non-violent struggle supports the same principle – it becomes efficient the moment people take it personally”
The first LSE India Summit took place in Goa 28-30 January 2016, and featured a wide range of panellists exploring topics from civil society to infrastructure challenges in India. During a pause in the conference, speakers Srdja Popović and Yogendra Yadav met to discuss political theory and the practicalities of fostering non-violent mass movements in the 21st Century

Rigorous Design of Fault-Tolerant Transactions for Replicated Database Systems using Event B
System availability is improved by the replication of data objects in a distributed database system. However, during updates, the complexity of keeping replicas identical arises due to failures of sites and race conditions among conflicting transactions. Fault tolerance and reliability are key issues to be addressed in the design and architecture of these systems. Event B is a formal technique which provides a framework for developing mathematical models of distributed systems by rigorous description of the problem, gradually introducing solutions in refinement steps, and verification of solutions by discharge of proof obligations. In this paper, we present a formal development of a distributed system using Event B that ensures atomic commitment of distributed transactions consisting of communicating transaction components at participating sites. This formal approach carries the development of the system from an initial abstract specification of transactional updates on a one copy database to a detailed design containing replicated databases in refinement. Through refinement we verify that the design of the replicated database confirms to the one copy database abstraction
