Identification of slow molecular order parameters for Markov model construction. [PDF]

Journal of Chemical Physics, 2013
A goal in the kinetic characterization of a macromolecular system is the description of its slow relaxation processes via (i) identification of the structural changes involved in these processes and (ii) estimation of the rates or timescales at which ...

Segmentation of brain MR images through a hidden Markov random field model and the expectation-maximization algorithm

IEEE Transactions on Medical Imaging, 2001
The finite mixture (FM) model is the most commonly used model for statistical segmentation of brain magnetic resonance (MR) images because of its simple mathematical form and the piecewise constant nature of ideal brain MR images.

Methodology for Evaluating the Impact of Sudden Failures on the Reliability Parameters of the Optical Cable Damaged Section

Proceedings of the International Conference on Applied Innovations in IT, 2023
An optical cable is considered as a multicomponent system, which components are elementary sections of an optical cable. During operation, due to failures of these sections, they are replaced with new ones.

Exploratory search during directed navigation in C. elegans and Drosophila larva

eLife, 2017
Many organisms—from bacteria to nematodes to insect larvae—navigate their environments by biasing random movements. In these organisms, navigation in isotropic environments can be characterized as an essentially diffusive and undirected process.
