Systematic vegetation index discovery for phenology-based crop mapping
Abstract Introduction: The Systematic Vegetation Index Discovery (SVID) framework generates and evaluates large numbers of vegetation indices (VIs) by combining spectral bands with basic arithmetic operations. We evaluated whether systematically discovered indices could improve agricultural land-cover classification compared with conventional indices such as NDVI while reducing the dimensionality of multitemporal spectral data.
Mapping peak flowering phenology of rapeseed ( Brassica napus ) in North Dakota using Landsat 8 and Sentinel-2
Abstract Detecting the peak flowering time of rapeseed (Brassica napus) is essential for optimizing crop management, improving yield forecasts, and enhancing pollination services. This study aimed to map and analyze the spatial and temporal patterns of peak flowering in spring rapeseed across North Dakota using satellite remote sensing.

CMAS corrosion resistance behavior and mechanism of Hf6Ta2O17/RETaO4 (RE = Yb, Y, Eu, Sm, and Nd) composite ceramics for thermal barrier coatings
Thermal barrier coatings (TBCs), as advanced thermal protective technologies, are essential for ensuring the high service lifetime and efficiency of aero engines [1], [2], [3]. Yttria-stabilized zirconia (YSZ) with low thermal conductivity and high fracture toughness is widely used as the ceramic coating material for TBCs [4], [5].

Trends in Pollination Scientists' Research: A Comprehensive Analysis in Citations and Research Topics
1 Introduction Since Sprengel's seminal publication in 1793 (Sprengel and Sprengel 1793) on the interactions between flowers and insects that transport pollen to plant stigmas, demonstrating their crucial role in seed and fruit production, our understanding of pollination as an essential ecosystem process has significantly expanded (Mayer et al. 2011).
G‐space versus E‐space: Are hornets (Hymenoptera: Vespidae) at equilibrium with honeybees in Asia?
1 INTRODUCTION The tendency of species to retain aspects of their fundamental niche over time is called niche conservatism (NC) (Wiens & Graham, 2005). If fundamental niches of species are conserved, species will only be able to invade regions that have a climate similar to that of their native range (Tirozzi et al., 2022). Moreover, if climatic tolerances are conserved, species should shift their geographic ranges in the face of global warming to track their ancestral climatic regime.
Energy‐based corridor identification for mammals between protected areas in Iran
1 INTRODUCTION Recent research conducted in Iran indicates that various human infrastructures such as roads, railways, urban areas, industries, mines, and agricultural activities have notable impacts on the country's protected areas (Karimi & Jones, 2020; Rahimi et al., 2023; Rahimi & Dong, 2022). These studies emphasize that such human activities can affect approximately 5.1%–30.3% of the total extent of protected areas in Iran (Rahimi & Dong, 2022).
