NOAA-20 and S-NPP VIIRS Thermal Emissive Bands On-Orbit Calibration Algorithm Update and Long-Term Performance Inter-Comparison

Remote Sensing, 2021
The Visible Infrared Imaging Radiometer Suite (VIIRS) on board the National Oceanic and Atmospheric Administration-20 (NOAA-20) and the Suomi National Polar-orbiting Partnership Program (S-NPP) satellites were launched in late 2017 and 2011, respectively.

Where Projects Fail: Geospatial Evidence of Delays and Cancellations in Chinese Development Finance

Journal of International Development, EarlyView.
ABSTRACT Delays and cancellations can severely undermine the effectiveness of development finance. Yet, little systematic evidence exists on where and why these disruptions occur within the rapidly expanding portfolio of Chinese‐financed development projects in Africa.

AI‐Powered GPR Characterization of Peatland Underground Cavity Induced by Smoldering Wildfire: A Laboratory Proof‐of‐Concept

Safety Science and Technology, EarlyView.
We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.

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.

VIIRS night-time lights [PDF]

International Journal of Remote Sensing, 2017
The Visible Infrared Imaging Radiometer Suite VIIRS Day/Night Band DNB collects global low-light imaging data that have significant improvements over comparable data collected for 40 years by the DMSP Operational Linescan System. One of the prominent features of DNB data is the detection of electric lighting present on the Earth’s surface.

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.

Methodology to identify ecologically matching areas and its applications in conservation planning

Conservation Biology, EarlyView.
Abstract Identifying ecologically matching areas is both challenging and critical for understanding spatial patterns of biodiversity and advancing conservation planning. However, existing approaches often lack spatial flexibility, overlook shape and size constraints, or rely on limited environmental parameters, reducing their effectiveness in real ...

The Political U: New Evidence on the Economic Costs of Hybrid Regimes

Economics &Politics, EarlyView.
ABSTRACT Recent research establishes a positive causal effect from democracy to income, although this evidence relies mostly on binary regime classifications. We extend the identification framework of Acemoglu et al. (2019) to a classification that distinguishes democracies, autocracies, and hybrid regimes for about 170 countries over 1960–2024.
