Canadian Journal of Statistics, EarlyView.Abstract Response‐based sampling is often used in modelling rare events from large, imbalanced data for efficiency. When modelling the event with logistic regression, the sampling design may be adjusted for using sampling weights or an offset. We propose a stratified sampling design for modelling rare events with large data which improves on previous ...

Molecular Ecology Resources, EarlyView., 2023 Abstract Understanding how genetic diversity is distributed across spatiotemporal scales in species of conservation or management concern is critical for identifying large‐scale mechanisms affecting local conservation status and implementing large‐scale biodiversity monitoring programmes.

Capacité de la méthode des microhabitats à prédire l'habitat de reproduction de la truite commune
Knowledge and Management of Aquatic Ecosystems, 1995 La méthode des microhabitats a été appliquée pour le stade reproduction de la truite commune sur 205 faciès d'écoulement, appartenant à 6 rivières des Pyrénées centrales. La relation entre Surface Pondérée Utile (SPU) et densité de frayères est meilleure

Adsorption of Mercury in Aqueous Solutions by Functionalized Cellulose Extracted from Soybean Hulls
ChemPlusChem, EarlyView.Reuse of agricultural waste as a source of adsorbent cellulose‐based materials is a low‐cost and sustainable approach to remove potentially toxic elements (PTEs) from aqueous solutions. This approach is successfully applied in the removal of mercury from aquaculture water, an important source of food where the absence of PTEs is a fundamental requisite

What's math got to do with patterns in fish? [PDF]
arXiv, 2021 When you think of fish, what comes to mind? Maybe you think of pet goldfish, movie characters like Dory or Nemo, or trout in a local river. One of the things that all of these fish have in common is patterns in their skin. Nemo sports black and white stripes in his orange skin, and trout have spots. Even goldfish have a pattern -- it's just plain gold (

Developmental Dynamics, EarlyView.Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Provably Optimal Control for Multiplicative Amplitude Control Noise [PDF]
arXiv, 2022 We provide a technique to obtain provably optimal control sequences for quantum systems under the influence of time-correlated multiplicative control noise. Utilizing the circuit-level noise model introduced in [Phys. Rev. Research 3, 033229(2021)], we show that we can map the problem of finding such a sequence to a convex optimization problem with ...

Plump Cutthroat Trout and Thin Rainbow Trout in a Lentic Ecosystem [PDF]
arXiv, 2012 Background: Much has been written about introduced rainbow trout (Oncorhynchus mykiss) interbreeding and outcompeting cutthroat trout (Oncorhynchus clarkii). However, the specific mechanisms by which rainbow trout and their hybrids outcompete cutthroat trout have not been thoroughly explored, and the published data is limited to lotic ecosystems ...

Area, EarlyView., 2022 This article uses examples from practice‐led‐research to explore the tensions between rewilding and the gendered embodied knowledge of upland farmers in an area of Wales, UK called the Cambrian Mountains. This paper argues that within the context of the polarising ideas of rewilding, sensitivity and the need to listen to the embodied, situated ...
