Molecular Ecology Resources, EarlyView.ABSTRACT The StairwayPlot approach provides an elegant, flexible and powerful method to estimate complex demographic histories of single populations from site frequency spectrum data. It uses expected coalescent times to compute the expected site frequency spectrum within a multinomial likelihood function.

FInCH: Fast statistical inference for continuous‐time animal movement
Methods in Ecology and Evolution, EarlyView.Abstract It is common for movement ecologists to model individual‐level animal movement in discrete time using methods such as hidden Markov models (HMMs). Although often the fitting of HMMs is computationally efficient, the key assumptions required to model in discrete time become limiting when dealing with temporally irregular data or an animal that ...

New perspectives on body size and shape evolution in dinosaurs
Biological Reviews, EarlyView.ABSTRACT Diversity in the body shapes and sizes of dinosaurs was foundational to their widespread success during the Mesozoic era. The ability to quantify body size and form reliably is therefore critical to the study of dinosaur biology and evolution.

Look past the cooperative eye hypothesis: reconsidering the evolution of human eye appearance
Biological Reviews, EarlyView.ABSTRACT The external appearance of the human eye has been prominently linked to the evolution of complex sociocognitive functions in our species. The cooperative eye hypothesis (CEH) proposes that human eyeballs, with their weakly expressed conjunctival and scleral pigmentation, are uniquely conspicuous and evolved under selective pressures to behave ...

The what, how, and why of trait‐based analyses in ecology
Ecography, EarlyView.Functional diversity is increasingly used alongside taxonomic diversity to describe populations and communities in ecology. Indeed, functional diversity metrics allow researchers to summarise complex occupancy patterns in space and/or time across communities and/or populations in response to various stressors.

WNT5a export onto extracellular vesicles studied at single‐molecule and single‐vesicle resolution
The FEBS Journal, EarlyView.WNT signaling, which orchestrates tissue development and homeostasis, is mediated by hydrophobic WNT proteins traveling from secreting to receiving cells on various carriers. Here, fusion constructs of fluorescent proteins with WNT5a were developed and functionally validated.

Elements of Nonequilibrium Statistical Mechanics, 2020
[en] The aim of this work is to study the Brownian motion from a theoretical approach. Brownian motion (also named Wiener process) is one of the best known stochastic processes and plays an important role in both pure and applied Mathematics. In the first chapter, we present the basic concepts of the theory of stochastic processes such as filtrations ...

Data-Driven Battery Health Prognosis Using Adaptive Brownian Motion Model
IEEE Transactions on Industrial Informatics, 2020Degradation dynamics modeling and health prognosis play extremely important roles in system prognostics and health management. Wiener process-based degradation models and remaining useful life (RUL) prediction methods have the advantage of high ...

Brownian Motion of an Ellipsoid
Science, 2006We studied the Brownian motion of isolated ellipsoidal particles in water confined to two dimensions and elucidated the effects of coupling between rotational and translational motion. By using digital video microscopy, we quantified the crossover from short-time anisotropic to long-time isotropic diffusion and directly measured probability ...
