Inflammatory Shift in Chronic Rhinosinusitis Amidst Guangzhou's Urbanization (2000–2018)

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) exhibits temporal and geographic diversity in pathological endotypes with progressive eosinophilic infiltration, while the underlying causes remain unclear. Current pathological endotypes determination relies on mean cell count per high‐power field, requiring accuracy optimization.

Adapting to Urban Heights: Multidimensional Gradients Drive Nest‐Selection Plasticity and Trade‐Offs in a Human‐Commensal Sparrow

Integrative Zoology, EarlyView.
Urban Eurasian tree sparrows exhibit pronounced nest‐site plasticity, exploiting vertical building space while preferring lower nest heights when sites are abundant. Nest decisions are driven by altitude and building height rather than other factors, indicating a shift toward anthropogenic resources in cities.

A Harmonized Landsat–Sentinel‐2 Burned‐Area Product for the Pantanal (2014–2024), Based on Multitemporal Composites

Geoscience Data Journal, Volume 13, Issue 3, July 2026.
This work presents AQM‐HLS, a harmonized burned‐area dataset for the Pantanal covering 2014–2024. Landsat‐8/9 and Sentinel‐2 imagery were integrated into multitemporal NBR composites and classified using Random Forest. The dataset captures fire‐scar dynamics, delivering accurate 30‐m burned‐area maps suitable for long‐term monitoring and environmental ...

Identification of Polycentric Cities in China Based on NPP-VIIRS Nighttime Light Data [PDF]

Remote Sensing, 2020
Nighttime light data play an important role in the research on cities, while the urban centers over a large spatial scale are still far from clearly understood. Aiming at the current challenges in monitoring the spatial structure of cities using nighttime light data, this paper proposes a new method for identifying urban centers for massive cities at ...
