A new rule for almost-certain termination of probabilistic and demonic programsDec 04 2016Extending our own and others' earlier approaches to proving termination of probabilistic programs, we propose and prove a new rule for "termination with probability one", also known as "almost-certain termination".

Analysis-suitable $G^1$ multi-patch parametrizations for $C^1$ isogeometric spacesSep 25 2015May 09 2016One key feature of isogeometric analysis is that it allows smooth shape functions. Indeed, when isogeometric spaces are constructed from $p$-degree splines (and extensions, such as NURBS), they enjoy up to $C^{p-1}$ continuity within each patch. However, ... More

Integrating Phase 2 into Phase 3 based on an Intermediate Endpoint While Accounting for a Cure ProportionJan 04 2019For a trial with primary endpoint overall survival for a molecule with curative potential, statistical methods that rely on the proportional hazards assumption may underestimate the power and the time to final analysis. We show how a cure proportion model ... More
Weak Concurrent Kleene Algebra with Application to Algebraic VerificationJan 30 2013We propose a generalisation of concurrent Kleene algebra \cite{Hoa09} that can take account of probabilistic effects in the presence of concurrency.

Compositional closure for Bayes Risk in probabilistic noninterferenceJul 07 2010We give a sequential model for noninterference security including probability (but not demonic choice), thus supporting reasoning about the likelihood that high-security values might be revealed by observations of low-security activity. Our novel methodological ... More
Microscopic spinon-chargon theory of magnetic polarons in the t-J modelJan 04 2019The interplay of spin and charge degrees of freedom, introduced by doping mobile holes into a Mott insulator with strong anti-ferromagnetic (AFM) correlations, is at the heart of strongly correlated matter such as high-Tc cuprate superconductors.
