The impact of experimental design choices on parameter inference for models of growing cell colonies [PDF]

Royal Society Open Science, 2018
To better understand development, repair and disease progression, it is useful to quantify the behaviour of proliferative and motile cell populations as they grow and expand to fill their local environment.

Emergence of canonical functional networks from the structural connectome

NeuroImage, 2021
How do functional brain networks emerge from the underlying wiring of the brain? We examine how resting-state functional activation patterns emerge from the underlying connectivity and length of white matter fibers that constitute its “structural ...

REHEATFUNQ (REgional HEAT-Flow Uncertainty and aNomaly Quantification) 2.0.1: a model for regional aggregate heat flow distributions and anomaly quantification [PDF]

Geoscientific Model Development
Surface heat flow is a geophysical variable that is affected by a complex combination of various heat generation and transport processes. The processes act on different lengths scales, from tens of meters to hundreds of kilometers.

Mapping species diversification metrics in macroecology: Prospects and challenges

Frontiers in Ecology and Evolution, 2022
The intersection of macroecology and macroevolution is one of today’s most active research in biology. In the last decade, we have witnessed a steady increment of macroecological studies that use metrics attempting to capture macroevolutionary processes ...

Hierarchical development of dominance through the winner-loser effect and socio-spatial structure.

PLoS ONE, 2022
In many groups of animals the dominance hierarchy is linear. What mechanisms underlie this linearity of the dominance hierarchy is under debate. Linearity is often attributed to cognitively sophisticated processes, such as transitive inference and ...

Multisensory causal inference in the brain [PDF]

, 2015
At any given moment, our brain processes multiple inputs from its different sensory modalities (vision, hearing, touch, etc.). In deciphering this array of sensory information, the brain has to solve two problems: (1) which of the inputs originate from ...

Algorithms of causal inference for the analysis of effective connectivity among brain regions

Frontiers in Neuroinformatics, 2014
In recent years, powerful general algorithms of causal inference have been developed. In particular, in the framework of Pearl’s causality, algorithms of inductive causation (IC and IC*) provide a procedure to determine which causal connections among ...

Monotonic Gaussian Process for spatio-temporal disease progression modeling in brain imaging data

NeuroImage, 2020
We introduce a probabilistic generative model for disentangling spatio-temporal disease trajectories from collections of high-dimensional brain images.

Systematic comparison of modeling fidelity levels and parameter inference settings applied to negative feedback gene regulation.

PLoS Computational Biology, 2022
Quantitative stochastic models of gene regulatory networks are important tools for studying cellular regulation. Such models can be formulated at many different levels of fidelity. A practical challenge is to determine what model fidelity to use in order

Fast and flexible estimation of effective migration surfaces

eLife, 2021
Spatial population genetic data often exhibits ‘isolation-by-distance,’ where genetic similarity tends to decrease as individuals become more geographically distant.
