Observations of methane net sinks in the upland Arctic tundra

This study focuses on direct measurements of CO2 and CH4 turbulent eddy covariance fluxes in tundra ecosystems on the Svalbard islands over a 2-year period. Our results reveal dynamic interactions between climatic conditions and ecosystem activities such as photosynthesis and microbial activity. During summer, pronounced carbon uptake fluxes indicate increased photosynthesis and microbial methane consumption, while during the freezing seasons very little exchange was recorded, signifying redu...

Multiclass CNN Approach for Automatic Classification of Dolphin Vocalizations

Highlights: What are the main findings? A CNN was developed for multiclass classification of dolphin vocalizations. The model achieved a 95.2% mean accuracy with a mean F1-score of 87.8%. What is the implication of the main finding? This approach enhances the passive acoustic monitoring of dolphin vocalizations. It provides a scalable AI-based solution for marine bioacoustics research. Monitoring dolphins in the open sea is essential for understanding their behavior and the impact of human ac...

First record of the African hind Cephalopholis taeniops (Valenciennes, 1828) in the NW Mediterranean Sea: a likely ship-borne introduction documented in collaboration with a recreational fisher

In October 2024, a single specimen of Cephalopholis taeniops, an Eastern Atlantic grouper, was captured by a recreational fisher near the port of Genoa, Italy (44 degrees 23 ' 2 '' N, 8 degrees 59 ' 34 '' E), in the Ligurian Sea. Here, we briefly report this unusual capture, which represents the northernmost Mediterranean record for the species, and we examine evidence suggesting a possible new and independent introduction likely related to ship transport.

SegAN for recognition of caries from 2D-panoramic x-ray images

Accurate recognition and segmentation of dental caries in 2D panoramic X-ray images are crucial for timely diagnosis and strategic treatment planning. The current study uses a Generative Adversarial Network (GAN) model named SegAN to segment the X-ray samples to recognize the caries. The SegAN model works in an adversarial architecture in which the generator focuses on creating precise segmentation maps of caries from 2D panoramic X-ray images. On the other hand, the discriminator ensures tha...

Comprehensive assessment of open science practices in indoor positioning: open data, code, and material

Transparency and verifiability have long been regarded as cornerstones of the scientific ethos and practice. However, persistent reproducibility challenges across numerous disciplines have brought renewed attention to the imperative for widespread adoption of open science practices. These considerations are particularly relevant to the research field of indoor positioning. Open data and open code sharing are gradually gaining traction in the field, but are still far from standard practice. Th...
