Choice experiments on land managers' participation in environmental programs: A systematic review and meta‐analysis of estimate validity

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Discrete choice experiments are increasingly being used to estimate land managers' willingness to accept participation in incentive‐based environmental programs. This is a specific application of discrete choice experiments: the estimation of willingness to accept for a private good (program participation) where respondents have to make trade ...

Mechanistische Diversität in der photoangeregten Radikal‐Redoxchemie: Eine kritische Evaluierung

open access: yesAngewandte Chemie, EarlyView.
Für viele prominente Beispiele der Photoredox‐Katalyse wird angenommen, dass sie über die Anregung einer offenschaligen („open‐shell“) Zwischenform des Katalysators ablaufen. Es wird jedoch intensiv darüber diskutiert, ob solche Mechanismen realistisch sind und, falls ja, wie genau sie ablaufen können.

Katalytische C–F‐Aktivierung bei Raumtemperatur: Enolat Kreuzkupplungen ermöglicht durch [Pd(1‐MeNAP)TFA]2 / LiHMDS

open access: yesAngewandte Chemie, EarlyView.
Katalysatoren, die aus dem Trifluoroacetat‐verbrückten Methylnaphthyl‐Palladium‐Dimer [Pd(1‐MeNAP)TFA]2 und Biarylphosphin‐Liganden generiert werden, in Kombination mit der Base LiHMDS, fördern α‐Arylierungsreaktionen verschiedener Enolate mit nicht‐aktivierten Arylfluoriden bei Raumtemperatur.

An ontological morphological phylogenetic framework for living and extinct ray‐finned fishes (Actinopterygii)

open access: yesThe Anatomical Record, EarlyView.
Abstract The ray‐finned fishes include one out of every two species of living vertebrates on Earth and have an abundant fossil record stretching 380 million years into the past. The division of systematic knowledge of ray‐finned fishes between paleontologists working on extinct animals and neontologists studying extant species has obscured the ...

Comparative study of two models to estimate solar radiation on an inclined surface

open access: yesRevue des Énergies Renouvelables, 2012
Our work is focused on the study of the solar radiation received on three inclined surface: 32°, 60° and 90° facing south. So, we proposed two theoretical models: Brichambaut and Liu Jordan models.

Cranial anatomy of a Late Cretaceous aspidorhynchid fish (Neopterygii: Aspidorhynchiformes) from Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

TERRA G-quadruplex RNA interaction with TRF2 GAR domain is required for telomere integrity

open access: yesScientific Reports, 2021
Telomere dysfunction causes chromosomal instability which is associated with many cancers and age-related diseases. The non-coding telomeric repeat-containing RNA (TERRA) forms a structural and regulatory component of the telomere that is implicated in ...

Near‐White Circularly Polarized Luminescence by Color Mixing Utilizing Surface‐Fluorophore‐Modified Cellulose Nanocrystals in Composite Films

open access: yesChemistry – A European Journal, EarlyView.
Robust, bio‐derived, and freestanding films based on cellulose nanocrystals (CNCs), covalently decorated with achiral fluorophores, transduce shape chirality and supramolecular helicity into near‐white circularly polarized luminescence (CPL). With composites covering the visible spectrum, near‐white, right‐handed CPL with high luminescence dissymmetry (
