A Storage Method for Remote Sensing Images Based on Google S2

open access: yesIEEE Access, 2020
When using HBase to store tiles of remote sensing images, the spatial position of a tile is often used as the first part of the tile's rowkey so that tiles with high spatial correlations are stored close together to improve query efficiency.

The Transdiagnostic Role of Emotion Regulation Difficulties and Repetitive Negative Thinking in Depression, Anxiety, and Their Comorbidity

open access: yesDepression and Anxiety, Volume 2026, Issue 1, 2026.
This study investigated emotion regulation (ER) difficulties and repetitive negative thinking (RNT) in individuals with depression, anxiety disorders, or both, compared to nonclinical controls. We aimed to determine which aspects of ER difficulties and RNT are transdiagnostic or specific to one of the disorders, and whether the presence of ...

How absolute biomass intake can alter nutrient profile interpretation in free‐ranging species: the case of protein intake in brown bears

open access: yesWildlife Biology, Volume 2025, Issue 6, November 2025.
If an animal eats a large amount of a diet of a low content of a macronutrient, it can still ingest a considerable amount of that macronutrient. Various animals have been shown to balance nutrient content with intake in this way. We use the brown bear Ursus arctos as a model species, given their recent classification as ‘low protein omnivores', to show
