Probing the out‐of‐equilibrium dynamics of driven colloids by X‐ray photon correlation spectroscopy

Journal of Applied Crystallography, Volume 58, Issue 2, Page 535-542, April 2025.
This article presents an application of X‐ray photon correlation spectroscopy (XPCS) to probe the out‐of‐equilibrium dynamics in a driven colloidal system. XPCS enables the investigation of direction‐dependent non‐equilibrium dynamics and the gradual return of the suspension to equilibrium Brownian behaviour.

Asymptotic synchronization of Kuramoto oscillators with time delay and non-universal interaction [PDF]

arXiv
We study the emergence of synchronization in the Kuramoto model on a digraph in the presence of time delays. Assuming the digraph is strongly connected, we first establish a uniform bound on the phase diameter and subsequently prove the asymptotic frequency synchronization of the oscillators under suitable assumptions on the initial configurations.

Improved order selection method for hidden Markov models: A case study with movement data

Methods in Ecology and Evolution, EarlyView.
Abstract Hidden Markov models (HMMs) are a versatile statistical framework commonly used in ecology to characterize behavioural patterns from animal movement data. In HMMs, the observed data depend on a finite number of underlying hidden states, generally interpreted as the animal's unobserved behaviour. The number of states is a crucial hyperparameter,

Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

Coexisting with large carnivores based on the Volterra principle

Conservation Biology, EarlyView.
Abstract Coexistence with large carnivores represents one of the world's highest profile conservation challenges. Ecologists have identified ecological benefits derived from large carnivores (and large herbivores), yet livestock depredation, perceived competition for shared game, risks to pets and humans, and social conflicts often lead to demands for ...

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Cortico‐cortical evoked potentials: Analytical techniques and emerging paradigms for epileptogenic zone localization

Epilepsia, EarlyView.
Abstract Cortico‐cortical evoked potentials (CCEPs) are an active electrophysiological technique used during intracranial electroencephalography to evaluate the effective connectivity and influence of therapeutic stimulation between distinct cortical regions and pinpoint epileptogenic zones (EZs) in patients with epilepsy.

Comparing Data‐Poor and Data‐Rich Stock Assessments to Generalise Guidance for Pacific Coral‐Reef Fisheries

Fish and Fisheries, EarlyView.
ABSTRACT The growing use of data‐poor fisheries models provides unprecedented access to compelling stock metrics and management scenarios for coral‐reef fisheries. Yet, it remains unclear how well the assumptions surrounding data‐poor models derived from extensive cold‐water fisheries fit the life histories and ecology of tropical coral‐reef fishes ...
