Exactly one unstable mode: a computer-assisted spectral count for Choptuik's critical spacetime under spherically symmetric perturbations

Choptuik's spacetime, the discretely self-similar solution at the threshold of black hole formation in the collapse of a massless scalar field, is expected to have exactly one unstable mode, whose growth rate λ determines the critical exponent γ = 1/λ ≈ 0.374. The existence of th...

Assemblage structure and ecological functions of dung beetles in exotic pastures in the Southwestern Amazon

Abstract The implementation of exotic pastures in the Amazon causes drastic negative impacts on its biodiversity. Nevertheless, some species with the ability to colonize pastures may provide important ecosystem services for livestock development in tropical pastures, as in the Am...

Effect of carcass electrical stimulation on sheep and goat meat quality: a meta-analysis study

Context The utilization of electrical stimulation (ES) in small ruminant carcasses is less common than in beef processing facilities. Nevertheless, ES shows promise in mitigating cold shortening and improving meat quality traits in small ruminants. Aim This meta-analysis assessed...

Phenotypic Analysis of the Anti-T. cruzi Activity of Natural Products Obtained from Brazilian Botanical Sources

Chagas disease, caused by Trypanosoma cruzi (T. cruzi), affects more than 6 million people worldwide, predominantly in Latin America. Current chemotherapy relies on Benznidazole (Bz) and Nifurtimox, which are associated with adverse effects and limited efficacy during chronic inf...
