Sampling from Dirichlet process mixture models with unknown concentration parameter: mixing issues in large data implementations
(Springer, 2015-09)We consider the question of Markov chain Monte Carlo sampling from a general stick-breaking Dirichlet process mixture model, with concentration parameter α . This paper introduces a Gibbs sampling algorithm that combines ... -
Sampling Latent States for High-Dimensional Non-Linear State Space Models with the Embedded HMM Method
(2018-09)We propose a new scheme for selecting pool states for the embedded Hidden Markov Model (HMM) Markov Chain Monte Carlo (MCMC) method. This new scheme allows the embedded HMM method to be used for efficient sampling in state ... -

Scanning electron diffraction tomography of strain
(IOP Publishing Ltd., 2020-11-11)Strain engineering is used to obtain desirable materials properties in a range of modern technologies. Direct nanoscale measurement of the three-dimensional strain tensor field within these materials has however been limited ... -
Schatten-von Neumann classes of integral operators
(Elsevier, 2021)In this work we establish sharp kernel conditions ensuring that the corresponding integral operators belong to Schatten-von Neumann classes. The conditions are given in terms of the spectral properties of operators acting ... -
Schrödinger equation for Sturm-Liouville operator with singular propagation and potential
(EMS Press, 16-04-2024)In this paper, we consider an initial/boundary value problem for the Schrödinger equation with the Hamiltonian involving the fractional Sturm–Liouville operator with singular propagation and potential. To construct a ... -
Search efficiency of discrete fractional Brownian motion in a random distribution of targets
(American Physical Society (APS), 2021-04)Efficiency of search for randomly distributed targets is a prominent problem in many branches of the sciences. For the stochastic process of Lévy walks, a specific range of optimal efficiencies was suggested under variation ... -
Search for Gravitational Waves Associated with Fast Radio Bursts Detected by CHIME/FRB during the LIGO-Virgo Observing Run O3a
(2023-10-01)We search for gravitational-wave (GW) transients associated with fast radio bursts (FRBs) detected by the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst Project, during the first part of the third observing ...
