Optimized spectral indices for global vegetation and water mapping using Sentinel-2
Scientific ReportsReliable mapping of vegetation and surface water from satellite imagery remains challenging, as common spectral indices can saturate at high biomass, show limited sensitivity across ecosystems, and confuse targets with soil, shadows, or built-up surfaces.

Long-Term Population Monitoring of the Karner Blue (Lepidoptera: Lycaenidae) in Wisconsin, 1990-2004 [PDF]
, 2018 We monitored Wisconsin populations of the Karner blue (Lycaeides melissa samuelis Nabokov, Lepidoptera: Lycaenidae) during 1990-2004. We surveyed consecutive spring and summer broods in two contiguous central Wisconsin counties (Jackson, Wood), starting ...

Evapotranpiration estimates from vegetation indices
Proceedings of the 4th Workshop on Agri-Food Research. WiA[SPA] En este trabajo se presenta una metodología de estimación de la evapotranspiración real (ETa) de la superficie terrestre a escala mensual a partir de imágenes de satélite de observación de la Tierra (MODIS Terra). Se basa esencialmente en el uso de un índice de vegetación (EVI, Enhanced Vegetation Index) y de datos de temperatura del aire.

Estimation of photosynthetic capacity using MODIS polarization: 1988 proposal to NASA Headquarters [PDF]
The remote sensing community has clearly identified the utility of NDVI (normalized difference vegetation index) and SR (simple ratio) and other vegetation indices for estimating such metrics of landscape ecology as green foliar biomass, photosynthetic ...

Engineered Bacteria‐Vesicle Delivered Lactate Reprogramming Boosts Tumor Radiosensitivity
Advanced Science, EarlyView.We engineered a bacterial‐vesicular dual‐delivery platform that targets LOx to colorectal tumors, enabling lactate clearance, immune microenvironment remodeling, and microbiota modulation. This microbe–metabolism synergistic strategy effectively sensitizes colorectal cancer to radiotherapy, offering a promising approach to overcome radioresistance ...
