Bayesian spatial modelling of geostatistical data using INLA and SPDE methods: A case study predicting malaria risk in Mozambique.

Spatial and spatio-temporal epidemiology

Moraga P, Dean C, Inoue J, Morawiecki P, Noureen SR, Wang F.
PMID: 34774255
Spat Spatiotemporal Epidemiol. 2021 Nov;39:100440. doi: 10.1016/j.sste.2021.100440. Epub 2021 Aug 03.

Bayesian spatial models are widely used to analyse data that arise in scientific disciplines such as health, ecology, and the environment. Traditionally, Markov chain Monte Carlo (MCMC) methods have been used to fit these type of models. However, these...

Stochastic resonance in noisy maps as dynamical threshold-crossing systems.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Matyjaskiewicz S, Holyst JA, Krawiecki A.
PMID: 11031558
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 2000 May;61(5):5134-41. doi: 10.1103/physreve.61.5134.

Interplay of noise and periodic modulation of system parameters for the logistic map in the region after the first bifurcation and for the kicked spin model with Ising anisotropy and damping is considered. For both maps two distinct symmetric...

Analysis of phase synchronization of coupled chaotic oscillators with empirical mode decomposition.

Physical review. E, Statistical, nonlinear, and soft matter physics

Goska A, Krawiecki A.
PMID: 17155163
Phys Rev E Stat Nonlin Soft Matter Phys. 2006 Oct;74(4):046217. doi: 10.1103/PhysRevE.74.046217. Epub 2006 Oct 30.

Empirical mode decomposition is investigated as a tool to determine the phase and frequency and to study phase synchronization between complex chaotic oscillators. Within this approach, the oscillator is characterized by a spectrum of frequencies corresponding to the empirical...

An algorithm for refinement of lattice parameters using CBED patterns.

PMID: 17123736
Ultramicroscopy. 2007 Apr-May;107(4):390-5. doi: 10.1016/j.ultramic.2006.10.003. Epub 2006 Nov 07.

A new algorithm for calculation of lattice parameters from convergent beam electron diffraction (CBED) patterns has been developed. Like most of the previous approaches to the problem, it is an optimization procedure matching geometric elements of high order Laue...

Stochastic resonance with spatiotemporal signal controlled by time delays.

Physical review. E, Statistical, nonlinear, and soft matter physics

Krawiecki A, Stemler T.
PMID: 14754174
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Dec;68(6):061101. doi: 10.1103/PhysRevE.68.061101. Epub 2003 Dec 17.

Stochastic resonance in two coupled threshold elements with input periodic signals shifted in phase is studied. For fixed phase shift and coupling strength the signal-to-noise ratio at the output of each element can be maximized by introducing proper time...

Determination of lattice parameters from multiple CBED patterns: a statistical approach.

Ultramicroscopy

Brunetti G, Bouzy E, Fundenberger JJ, Morawiec A, Tidu A.

Ultramicroscopy. 2010 Mar;110(4):269-77. doi: 10.1016/j.ultramic.2009.11.004. Epub 2009 Dec 16.

This study deals with the uncertainty of the measurement of lattice parameters by CBED using the kinematic approximation. The analysis of a large number of diffraction patterns acquired on a silicon sample at 93 K with a LaB(6) TEM...

Indexing of diffraction patterns for determination of crystal orientations.

Acta crystallographica. Section A, Foundations and advances

Morawiec A.
PMID: 33125355
Acta Crystallogr A Found Adv. 2020 Nov 01;76:719-734. doi: 10.1107/S2053273320012802. Epub 2020 Oct 29.

The task of determining the orientations of crystals is usually performed by indexing reflections detected on diffraction patterns. The well known underlying principle of indexing methods is universal: they are based on matching experimental scattering vectors to some vectors...

Stochastic multiresonance due to interplay between noise and fractals.

Physical review. E, Statistical, nonlinear, and soft matter physics

Matyjaśkiewicz S, Krawiecki A, Hołyst JA, Schimansky-Geier L.
PMID: 12935234
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Jul;68(1):016216. doi: 10.1103/PhysRevE.68.016216. Epub 2003 Jul 21.

Stochastic multiresonance is shown to occur in a general class of threshold-crossing systems, in which a derivative of the threshold-crossing probability with respect to a system parameter is a nonmonotonic function of the noise intensity. As an example, a...

Blowout bifurcation and stability of marginal synchronization of chaos.

Physical review. E, Statistical, nonlinear, and soft matter physics

Krawiecki A, Matyjaśkiewicz S.
PMID: 11580431
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Sep;64(3):036216. doi: 10.1103/PhysRevE.64.036216. Epub 2001 Aug 28.

Blowout bifurcations are investigated in a symmetrized extension of the replacement method of chaotic synchronization which consists of coupling chaotic systems via mutually shared variables. The coupled systems are partly linear with respect to variables that are not shared,...

Volume of intersection of two balls in orientation space.

Acta Crystallogr A. 2010 Nov;66:717-9. doi: 10.1107/S0108767310035403. Epub 2010 Sep 28.

Orientations deviating from an ideal orientation by angles not exceeding a given limit constitute a ball in the metric space of orientations. Such balls arise in crystallographic computations, and in some cases intersections of the balls are of interest....

Stochastic multiresonance in a chaotic map with fractal basins of attraction.

Noise-free stochastic resonance in a chaotic kicked spin model at the edge of the attractor merging crisis is considered. The output signal reflects the occurrence of crisis-induced jumps between the two parts of the attractor. As the control parameter-the...
