recommendations! Published in 2025 at "Applied Stochastic Models in Business and Industry"

DOI: 10.1002/asmb.70056

Abstract: A new sparse recursive filtering is suggested for the efficient inference of the joint posterior of the number of change points and their locations. The computational and storage costs of the sparse recursive filtering are… read more here.

recommendations! Published in 2020 at "ELECTROPHORESIS"

DOI: 10.1002/elps.201900399

Abstract: A novel combination of CE‐based separation techniques was used for the precise fractionation of ionic compounds from impurities. The combination of on‐capillary concentration and separation using transient isotachophoresis, with multiple injections and a two‐point detection… read more here.

recommendations! Published in 2017 at "Statistics in medicine"

DOI: 10.1002/sim.7151

Abstract: Many functional neuroimaging-based studies involve repetitions of a task that may require several phases, or states, of mental activity. An appealing idea is to use relevant brain regions to identify the states. We developed a… read more here.
