Deforestation is an environmental problem that significantly impacts biodiversity and climate change. Deforestation detection is usually performed using optical remote sensing images, limiting the detection capability to the dry season in which image

This study found that millennial periods of higher rainfall combined with rising sea level enhanced sediment accumulation in Amazonian rivers valleys. This fuelled synchronous expansion of vegetation adapted to seasonally flooded substrates and its s

Neural architecture search (NAS) is a subset of automated machine learning that tries to find the best neural network to perform a given task. In this article, a network search space is defined and applied to perform the semantic segmentation of sate

Abstract Structural accidents due to punching shear failures have been reported in flat slab buildings. Design recommendations presented by codes can lead to entirely different punching shear resistance estimates for similar situations. Furthermore,

Abstract Punching is a possible failure mode for slender footings and it may lead a structure to ruin through progressive collapse. Although footing present different geometric characteristics, their punching shear design is based on the empirical me

This paper focuses on how the production and polarization of gravitational waves are affected by spontaneous Lorentz symmetry breaking, which is driven by a self-interacting vector field. Specifically, we examine the impact of a smooth quadratic pote

Tree species mapping in tropical forests provides valuable insights for forest managers. Keystone species can be located for collection of seeds for forest restoration, reducing fieldwork costs. However, mapping of tree species in tropical forests us

A resistência ao cisalhamento de lajes nervuradas unidirecionais de concreto armado sem estribos nas nervuras ainda gera controvérsias quando sua estimativa não considera a contribuição da capa monolítica. Visando contribuir para o melhor enten

A passagem de tubulações em elementos estruturais ainda merece atenção especial dos projetistas, principalmente quando o modo de ruptura dos mesmos pode ser alterado devido às mudanças em seus comportamentos. Este trabalho compara os resultados
