Drivers and barriers associated with the intention–certification gap in hotel sustainability across mature Greek island destinations

Island destinations depend heavily on the hospitality sector, a major driver of tourism consumption that often results in excessive use of resources, particularly in mature and highly seasonal destinations. This study examines the barriers and drivers associated with hotel sustai...

Study of Supernova Neutrinos at ESSnuSB

In this paper, we have studied the sensitivity of the ESSnuSB far detector to supernova neutrinos. ESSnuSB is a proposed long-baseline neutrino experiment in Sweden, which will use a 538 kt water Cherenkov detector to probe the leptonic phase δCP by studying the second oscillatio...

Cross-Platform Mapping of Aboveground Carbon Storage Using MLS, UAV LiDAR, GEDI, and Sentinel-2 in a Romanian Mountain Forest

Forest landscapes used for recreation also provide climate-regulating services that are often absent from spatial planning. We mapped aboveground biomass density (AGBD) and aboveground carbon storage in the Postavaru-Piatra Mare mountain landscape near Brașov, Romania, using a cr...

Serum Redox Biomarkers in Canine Mast Cell Tumors: Exploratory Associations with Proliferative Activity and Clinicopathological Features

Canine mast cell tumors (MCTs) exhibit heterogeneous biological behavior and provide a clinically relevant setting in which relationships between tumor phenotype and systemic redox homeostasis can be investigated. This exploratory prospective cohort study evaluated complementary...
