Non-equilibrium multi-scale analysis and coexistence in competing first passage percolation

The main contribution of this paper is the development of a novel approach to multi-scale analysis that we believe can be used to analyse processes with non-equilibrium dynamics. Our approach will be referred to as...

Coexistence in competing first passage percolation with conversion

We introduce a two-type first passage percolation competition model on infinite connected graphs as follows. Type 1 spreads through the edges of the graph at rate 1 from a single distinguished site, while all other sites are...

Spatial models generated by nested stochastic partial differential equations, with an application to global ozone mapping
David Bolin, Finn Lindgren
Mar 01, 2011
A new class of stochastic field models is constructed using nested stochastic partial differential equations (SPDEs). The model class is computationally efficient, applicable to data on general smooth manifolds, and includes...

Excursion and contour uncertainty regions for latent Gaussian models
David Bolin, Finn Lindgren
Jan 01, 2015
In several areas of application ranging from brain imaging to astrophysics and geostatistics, an important statistical problem is to find regions where the process studied exceeds a certain level. Estimating such regions so that...

Bayesian Spatial Modelling with R-INLA
Finn Lindgren, Håvard Rue
Feb 01, 2015
The principles behind the interface to continuous domain spatial models in the R- INLA software package for R are described. The integrated nested Laplace approximation (INLA) approach proposed by Rue, Martino, and Chopin (2009)...

Large spatial data sets require innovative techniques for computationally efficient statistical estimation. In this comment some aspects of local predictor selection are explored, with a view towards spatially coherent field...

Parasite species richness and its effect on persistence in food webs

Parasitic species are likely to have a significant effect on the stability of ecosystems. However, little is known of the nature of this effect, with debate over whether it is positive or negative. In previous work it was...

Selective Axonal Expression of the Kv1 Channel Complex in Pre-myelinated GABAergic Hippocampal Neurons.
In myelinated fibers, the voltage-gated sodium channels Nav1 are concentrated at the nodal gap to ensure the saltatory propagation of action potentials. The voltage-gated potassium channels Kv1 are segregated at the...

Moving forward with prisms
It is postulated that the decreased walking speed; small, shuffling steps; and "freezing" shown by patients with Parkinson's disease could stem from an inability to tilt the body forward enough to provide sufficient forward...

Spatio-temporal modeling of particulate matter concentration through the SPDE approach
In this work, we consider a hierarchical spatio-temporal model for particulate matter (PM) concentration in the North-Italian region Piemonte. The model involves a Gaussian Field (GF), affected by a measurement error, and a...

Institutional Complexity and Individual Responses
Research highlights how coexisting institutional logics can sometimes offer opportunities for agency to enterprising actors in organizational fields. But macro- and micro-level studies using this framework diverge in their...

Positive Schizotypy and the Experience of Creativity:
Positive schizotypy has been shown to predict emergence of schizophrenia-spectrum disorders, with suspiciousness/paranoia regarded a key risk factor. However, magical thinking and unusual perceptual experiences, other aspects of...
