A new smooth failure criterion for concrete inspired by Lubliner's condition

Structural Concrete, EarlyView.
Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

Environmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Characterisation of the Mesial Root and Middle Mesial Canal Morphology in Mandibular First Molars: An Ex Vivo Micro‐CT Study

Australian Endodontic Journal, EarlyView.
ABSTRACT This ex vivo study characterised the mesial root morphology of mandibular first molars with a middle mesial canal (MMC) using micro‐CT. Among 469 scanned molars, 42 (8.96%) presented an MMC. Morphological parameters analysed included canal configuration, chamber orifice features, dentine thickness, isthmus type, and aspect ratio.

Networks of coercion: Military ties and civilian leadership challenges in China

American Journal of Political Science, EarlyView.
Abstract Civilian‐led coups are one of the most common routes to losing power in autocracies. How do authoritarian leaders secure themselves from civilian leadership challenges? We argue that autocrats differentiate civilian rivals in part by their social ties to the military.

Reviewing fast or slow: A theory of summary reversal in the judicial hierarchy

American Journal of Political Science, EarlyView.
Abstract Appellate courts with discretionary dockets have multiple ways to review lower courts. We develop a formal model that evaluates the trade‐offs between “full review”—which features full briefing, oral arguments, and signed opinions—versus “quick review,” where a higher court can summarily reverse a lower court. We show that having the option of
