The quasipotential with respect to a given attractor of a system, evolving according to a
stochastic differential equation (SDE) with a small noise, is a function that allows us to find the …

The study of phenomena such as protein folding and conformational changes in molecules
is a central theme in chemical physics. Molecular dynamics (MD) simulation is the primary …

We address the problem of estimating seismic velocities inside the Earth which is necessary
for obtaining seismic images in regular Cartesian coordinates. The main goals are to …

… The authors declare the following financial interests/personal relationships which may be
considered as potential competing interests: Maria Cameron and Zhigang Suo reports …

The study of rare events in molecular and atomic systems such as conformal changes and
cluster rearrangements has been one of the most important research themes in chemical …

Nongradient SDEs with small white noise often arise when modeling biological and ecological
time-irreversible processes. If the governing SDE were gradient, the maximum likelihood …

Transition path theory (TPT) is a mathematical framework for quantifying rare transition events
between a pair of selected metastable states $A$ and $B$. Central to TPT is the committor …

We present algorithms for solving high-frequency acoustic scattering problems in complex
domains. The eikonal and transport partial differential equations from the WKB/geometric …

QPot is an R package for analyzing two-dimensional systems of stochastic differential
equations. It provides users with a wide range of tools to simulate, analyze, and visualize the …

OBJECTIVE To characterize clinical, clinicopathologic, and hepatic histopathologic features
and outcome for dogs with probable ketoconazole-induced liver injury. ANIMALS 15 dogs …
