Divergent trajectories of genome architecture and chromosome evolution in ferns and angiosperms
New Phytologist, EarlyView.Variation in key fern genomic traits across families, mapped onto a summary phylogenetic tree. Summary Ferns and angiosperms represent the two largest vascular plant lineages but exhibit striking genomic and ecological contrasts. We investigated whether differences in genome size, chromosome architecture, GC content, and stomatal traits reveal ...

Journal of Forecasting, Volume 45, Issue 6, Page 2905-2941, September 2026.ABSTRACT This paper adopts a bivariate Markov‐switching multifractal (BMSM) model to reexamine comovement in SV between commodity, foreign exchange (FX), and stock markets. After the 2007–2008 global financial crisis understanding volatility linkages and the correlation structure between these markets becomes very important for risk analysts, portfolio

Advanced Intelligent Discovery, Volume 2, Issue 4, August 2026.Exosomes are emerging as powerful biomarkers for disease diagnosis and monitoring. This review highlights the integration of surface‐enhanced Raman spectroscopy with artificial intelligence to enhance molecular fingerprinting of exosomes. Machine learning and deep learning techniques improve spectral interpretation, enabling accurate classification of ...

Timing in the presence of directional predictability: optimal stopping of skew Brownian motion [PDF]
Mathematical Methods of Operations Research, 2017 We investigate a class of optimal stopping problems arising in, for example, studies considering the timing of an irreversible investment when the underlying follows a skew Brownian motion. Our results indicate that the local directional predictability modeled by the presence of a skew point for the underlying has a nontrivial and somewhat surprising ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

On general skew Brownian motions
, 2018 The aim of this paper is two-fold. On one hand, we will study the distorted Brownian motion on $\mathbb{R}$, i.e. the diffusion process $X$ associated with a regular and strongly local Dirichlet form obtained by the closure of $\mathscr{E}(f,g)=\frac{1}{2}\int_\mathbb{R} f'(x)g'(x)ρ(x)dx$ for $f,g\in C_c^\infty(\mathbb{R})$ on $L^2(\mathbb{R ...

Optimal deep learning activity recognition pipeline using animal bio‐logging data
Methods in Ecology and Evolution, Volume 17, Issue 8, Page 2309-2329, August 2026.Abstract Animal activity recognition using supervised machine learning on bio‐logging data has revolutionized behavioural studies on wildlife and livestock over the past decade. These studies' analytic pipelines differ substantially though, being based on various sensors, features, algorithms and hyperparameter values, which has caused suboptimal or ...

Genetic Composition Is Unrelated to Song Content in a Wild Passerine
Molecular Ecology, Volume 35, Issue 15, August 2026.ABSTRACT Birdsong is a key sexual signal that varies substantially among individuals and populations. Understanding whether song similarity reflects genetic similarity is central for evaluating its role in sexual selection, population divergence and evolutionary dynamics, although partial vocal learning can obscure this relationship in many species ...
