Computational methods of EEG signals analysis for Alzheimer’s disease classification.
Computational analysis of electroencephalographic (EEG) signals have shown promising results in detecting brain disorders, such as Alzheimer's disease (AD). AD is a progressive neurological illness that causes neuron cells degeneration, resulting in cognitive impairment. While there is no cure for A...

Estimating public transport emissions from General Transit Feed Specification data.
This paper introduces the gtfs2emis model, a bottom-up method available as an R package to estimate emissions of public transport systems. The method uses General Transit Feed Specification (GTFS) data, a standard format for public transport data widely adopted worldwide, which makes the method easi...

Socio-environmental vulnerability to drought conditions and land degradation: an assessment in two northeastern Brazilian river basins.
over the past few decades, a significant amount of agricultural land has been lost due to soil degradation/desertification. in addition, the increasing frequency of extreme events, such as intense droughts and forest fires, has negatively impacted various ecosystem services. two of the main brazilia...

Genetic viability and habitat suitability of the critically endangered southern muriqui (Brachyteles arachnoides) in the Atlantic Forest’s fragmented landscapes under land use and climate change scenarios.
The joint effects of climate change and landscape fragmentation to the genetic viability of isolated populations has barely been addressed for the Atlantic Forest fauna. Therefore, this work explored the potential habitat suitability for the southern muriqui (Brachyteles arachnoides), by modeling cl...

Nitrogen management in Brazil: emissions dynamics, sustainability, and policy responses.
Nitrogen pollution is one of the most widespread and challenging problems in Brazil, being the cause of several environmental and health issues. The focus of this thesis is to investigate the underlying drivers of reactive nitrogen emissions, the sustainability of nitrogen use, and the policy respon...

Quantifying carbon loss at forests degraded by logging with repeated airborne Lidar data in the Brazilian Amazon.
Forest degradation is a major issue and a key component of tropical forests and carbon emissions. In this study, we use repeated Airborne Laser Scanning (ALS) data to quantify carbon losses in degraded forests due to logging at the Mato Grosso state rainforests. We identified logged areas using Plan...

U-BAD: Ultimate Burned Area Detection.
Here, we evaluated the combination of five satellites/sensors for improving burned area (BA) detection over the Amazon basin. Using a data set of 2,400 burn/no burn points by visual inspection in 2016, we investigated several spectral indices and ingested them into data mining algorithms to evaluate...

Taxa de crescimento da biomassa acima do solo em florestas secundárias amazônicas estimada por sensoriamento remoto LiDAR e hiperespectral.
A compreensão da taxa de crescimento da biomassa acima do solo (BAS) em florestas sob regeneração natural é essencial para mensurar o sequestro de carbono florestal e auxiliar na mitigação das mudanças climáticas. Neste estudo, estimamos a BAS em 57 amostras de florestas secundárias amazôn...

Moisture origins of the Amazon carbon source region.
The southeastern Amazon has recently been shown to be a net carbon source, which is partly caused by drying conditions. Drying depends on a number of factors, one of which is the land cover at the locations where the moisture has originated as evaporation. Here we assess for the first time the origi...

A decentralized approach to model national and global food and land use systems.
The achievement of several sustainable development goals and the Paris Climate Agreement depends on rapid progress towards sustainable food and land systems in all countries. We have built a flexible, collaborative modeling framework to foster the development of national pathways by local research t...
