Print Conventions and Authority in Three English Recipe Manuscripts

open access: yesRenaissance Studies, EarlyView.
Abstract This article considers the uses of stylistic and visual conventions drawn from print books in three seventeenth‐ and eighteenth‐century recipe manuscripts at the University of Pennsylvania. We begin by analysing the title page, dedicatory epistle, catchwords, and headers of MS Codex 627, which imitates an edition of Hugh Plat's Delights for ...

Simulation of the Intake and Compression Strokes of a Motored 4-Valve Si Engine with a Finite Element Code Simulation de l'admission et de la compression dans un moteur 4-soupapes AC entraîné à l'aide d'un code de calcul à éléments finis

open access: yesOil & Gas Science and Technology, 2006
A CFD code, using a mixed finite volumes - finite elements method on tetraedrons, is now available for engine simulations. The code takes into account the displacement of moving walls such as piston and valves in a full automatic way: a single mesh is ...

Robust multitask feature learning with adaptive Huber regressions

open access: yesCanadian Journal of Statistics, Volume 53, Issue 4, December 2025.
Abstract When data from multiple tasks have outlier contamination, existing multitask learning methods perform less efficiently. To address this issue, we propose a robust multitask feature learning method by combining the adaptive Huber regression tasks with mixed regularization. The robustification parameters can be chosen to adapt to the sample size,

Noisy matrix completion for longitudinal data with subject‐ and time‐specific covariates

open access: yesCanadian Journal of Statistics, Volume 53, Issue 3, September 2025.
Abstract In this article, we consider the imputation of missing responses in a longitudinal dataset via matrix completion. We propose a fixed‐effect, longitudinal, low‐rank model that incorporates both subject‐specific and time‐specific covariates. To solve the optimization problem, a two‐step optimization algorithm is proposed, which provides good ...

Racket sociality: investigating intimidation in North India

open access: yesJournal of the Royal Anthropological Institute, Volume 31, Issue 3, Page 771-788, September 2025.
This article is an ethnographic investigation into acts of intimidation and threats. Theoretically, it dialogues with ‘racket’ – a key analytical term in the sociology of domination, state‐making, and mafias. The anthropology of power, violence, and crime has paid scant attention to the morphology of threats and the ways interpersonal intimidation ...
