Machine Learning‐Based Estimation of Reference Evapotranspiration and Crop Coefficients for Wheat Under Diverse Climatic Conditions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Accurate estimation of reference evapotranspiration (ET0) and crop coefficients (Kc) is critical for irrigation planning, particularly in data‐limited regions where agriculture dominates freshwater consumption. Although machine learning (ML) methods have been widely applied to ET0 and Kc estimation, most studies address these parameters ...

Similarity and substitution: Using pile sorting methods to explore economic behavior

open access: yesJournal of the Agricultural and Applied Economics Association, EarlyView.
Abstract Despite the common intuition that similar products are stronger demand substitutes, this study shows a more nuanced relationship between perceived similarity and utility substitution. Using pile sorting, a method where items are sorted into groups according to their similarity, we conduct large‐scale consumer surveys on purchasing 21 foods for

Capture of adeno‐associated viruses from clarified lysate by continuous flow ultracentrifugation: a comparative study of iodixanol and sucrose gradients

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Adeno‐Associated Virus vectors are widely used in gene therapy due to their safety and efficacy. Despite the interest in their therapeutical application, AAV purification remains a significant challenge. Density gradient ultracentrifugation using cesium chloride, sucrose, or iodixanol gradients are common methods for AAV ...

Long‐Term Variability and Spatial Differentiation of the Frost‐Free Period in Iceland

open access: yesInternational Journal of Climatology, EarlyView.
Warming in Iceland (May–September) is expressed as fewer Tmin < 0°C days in the interior and more Tmin > 0°C days along the coasts. ABSTRACT Climate change in subarctic regions leads to significant transformations in thermal conditions; however, the long‐term variability of the frost‐free season (FFS)—and consequently, the growing period—remains poorly
