New Phytologist, Volume 252, Issue 2, Page 926-935, October 2026.Tip Quantification enables quantitative analyses over versatile selections of regions of interest. Summary Cell polarity and tip growth rely on the dynamic spatial organization of signaling and structural components. Quantitative characterization of these spatiotemporal dynamics is critical for understanding polarized cell growth, yet manual ...

Progressive Dehydrogenation of LiNH2 Materials on Ru(0001) Based on ab initio Interface Models
Journal of Computational Chemistry, Volume 47, Issue 23, September 5, 2026.Density Functional Theory models of Ru(0001) interfaced with LiNH2, Li2NH, and Li3N show how progressive dehydrogenation stabilizes Li–N–H/Ru interfaces. Calculations using GGA–PBE and PBE–dDsC functionals show that (100) surface orientations minimize lattice mismatch with Ru, thus promoting interface formation.

Sur les données de comptage dans le cadre des valeurs extrêmes et la modélisation multivariée [PDF]
Cette thèse s'intéresse à certains aspects théoriques de la modélisation des données de comptage. Deux cadres distincts sont abordés : celui des valeurs extrêmes et celui de la modélisation multivariée.

Canadian Journal of Administrative Sciences / Revue Canadienne des Sciences de l'Administration, Volume 43, Issue 3, September 2026.ABSTRACT This study examines how dynamic capabilities influence supply chain management in SMEs during systemic crises. A literature review identifies key strategies used by Canadian SMEs to enhance resilience, such as inventory increases, production adjustments, supplier diversification and product adaptation.

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Canadian Journal of Statistics, Volume 54, Issue 3, September 2026.Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Partial identification with categorical data and nonignorable missing outcomes
Canadian Journal of Statistics, Volume 54, Issue 3, September 2026.Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.

Bayesian inverse ensemble forecasting for COVID‐19
Canadian Journal of Statistics, Volume 54, Issue 3, September 2026.Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...

Canadian Journal of Statistics, Volume 54, Issue 3, September 2026.Abstract Annual tree growth is a complex biological process. Modelling radial growth in the trunk by linear‐circular regression with one mode and correlated errors has allowed the definition and assessment of a preferred direction for 1 and 2 years. Here, modified F$$ F $$‐tests are presented for 3 years, 1 mode/year; 1 year, 2 modes for possible main ...
