Size matters: a new view of the relationship between shape and size for molten volcanic ballisticsNARA Subscribed
Volcanic ballistic projectiles (VBPs) are a common hazard near volcanic vents and often threaten volcano tourists, especially at accessible volcanoes with Strombolian eruption style. Current ballistic hazard models used to estimate potential VBP impact zones often assume round and solid (fixed shape) projectiles, though the validity of these assumptions remains uncertain. In this study, we use high-speed video observations to...
Enhancement and restoration algorithms are widely used in the exploration of coral reefs for improving underwater images. However, by selecting an improvement algorithm based on image quality metrics, image processing key factors such as the execution time are not considered. In response to this issue, herein is presented a novel method built on multicriteria decision analysis that evaluates the processing time and feature poi...
A Probabilistic View of Forbidden Links: Their Prevalence and Their Consequences for the Robustness of Plant–Hummingbird CommunitiesNARA Subscribed
The presence in ecological communities of unfeasible species interactions, termed forbidden links, due to physiological or morphological exploitation barriers has been long debated, but little direct evidence has been found. Forbidden links are likely to make ecological communities less robust to species extinctions, stressing the need to assess their prevalence. Here, we used a dataset of plant–hummingbird interactions, coupl...
Optimization of an isolated photovoltaic water pumping system with technical–economic criteria in a water users associationNARA Subscribed
With proper management, the modernization of irrigation systems makes it possible to improve the efficiency of application and use of water at the cost of an increase in pumping needs and, therefore, an increment of the energy consumed. The recent drastic price increase for energy put the viability of many farms at risk. In this context, using photovoltaic solar energy to power pumping stations has become an increasingly attra...
The Ontology of Biological Attributes (OBA)—computational traits for the life sciencesNARA Subscribed
Existing phenotype ontologies were originally developed to represent phenotypes that manifest as a character state in relation to a wild-type or other reference. However, these do not include the phenotypic trait or attribute categories required for the annotation of genome-wide association studies (GWAS), Quantitative Trait Loci (QTL) mappings or any population-focussed measurable trait data. The integration of trait and biol...
Analysis of the cytotoxic and genotoxic effects in a population chronically exposed to coal mining residuesNARA Subscribed
During coal mining activities, many compounds are released into the environment that can negatively impact human health. Particulate matter, polycyclic aromatic hydrocarbons (PAHs), metals, and oxides are part of the complex mixture that can affect nearby populations. Therefore, we designed this study to evaluate the potential cytotoxic and genotoxic effects in individuals chronically exposed to coal residues from peripheral b...
The functional structure of plant communities drives soil functioning via changes in soil abiotic propertiesNARA Subscribed
While biodiversity is expected to enhance multiple ecosystem functions (EFs), the different roles of multiple biodiversity dimensions remain difficult to disentangle without carefully designed experiments. We sowed plant communities with independent levels of functional (FD) and phylogenetic diversities (PD), combined with different levels of fertilization, to investigate their direct and indirect roles on multiple EFs, includ...
