DOI: 10.1002/sim.9142
Abstract: The increasingly widespread use of meta-analysis has led to growing interest in meta-analytic methods for rare events and sparse data. Conventional approaches tend to perform very poorly in such settings. Recent work in this area… read more here.

DOI: 10.1017/jfm.2021.957
Abstract: Abstract This text presents one of the first successful applications of a rare events sampling method for the study of multistability in a turbulent flow without stochastic energy injection. The trajectories of collapse of turbulence… read more here.

DOI: 10.1021/acsomega.0c03892
Abstract: Here, we introduce the open-source software framework wepy (https://github.com/ADicksonLab/wepy) which is a toolkit for running and analyzing weighted ensemble (WE) simulations. The wepy toolkit is in pure Python and as such is highly portable and… read more here.

DOI: 10.1063/1.5082640
Abstract: Rare events in nonlinear dynamical systems are difficult to sample because of the sensitivity to perturbations of initial conditions and of complex landscapes in phase space. Here, we discuss strategies to control these difficulties and… read more here.

Sampling rare events across dynamical phase transitions.

DOI: 10.1063/1.5091669
Abstract: Interacting particle systems with many degrees of freedom may undergo phase transitions to sustain atypical fluctuations of dynamical observables such as the current or the activity. In some cases, this leads to symmetry-broken space-time trajectories… read more here.

DOI: 10.1080/03610926.2016.1217022
Abstract: ABSTRACT We present a new inverse sampling design for surveys of rare events, Gap-Based Inverse Sampling. In the design, sampling stops if after a predetermined interval, or gap, no new rare events are found. The… read more here.

Decay of correlations and laws of rare events for transitive random maps

DOI: 10.1088/1361-6544/aa64e8
Abstract: We show that a uniformly continuous random perturbation of a transitive map defines an aperiodic Harris chain which also satisfies Doeblin's condition. As a result, we get exponential decay of correlations for suitable random perturbations… read more here.

DOI: 10.1088/1478-3975/aa6d89
Abstract: The intrinsic stochasticity of gene expression can give rise to large fluctuations and rare events that drive phenotypic variation in a population of genetically identical cells. Characterizing the fluctuations that give rise to such rare… read more here.

DOI: 10.1093/bib/bbw107
Abstract: When building classifiers, it is natural to require that the classifier correctly estimates the event probability (Constraint 1), that it has equal sensitivity and specificity (Constraint 2) or that it has equal positive and negative… read more here.
