ABSTRACT New agricultural operating entities (NAOEs) are the organizational core of modern agricultural systems, yet whether and how they draw smallholders into green production remains empirically unsettled. Using survey data from 803 vegetable growers in Shandong Province, China, and combining the coefficient of variation method, propensity score ...

Reduced Order Modeling for Tsunami Forecasting With Bayesian Hierarchical Pooling
Abstract Reduced‐order models (ROMs) can represent spatiotemporal processes in significantly fewer dimensions and can often be solved many orders of magnitude faster than their governing partial differential equations (PDEs). For example, proper orthogonal decomposition yields a ROM in which the state is represented as a low‐dimensional linear ...

Abstract This paper evaluates the Arkansas “Most Crop per Drop” Irrigation Yield Contest, a novel competition‐based Extension program designed to increase the adoption of Irrigation Water Management (IWM) practices among farmers. We use survey data to classify producers into three categories: contestants, informed non‐participants with some connection ...

Abstract Offshore freshened groundwater (OFG) is a significant yet underexplored component of global water resources, occurring widely along many continental margins. However, its dynamics remain poorly constrained due to limited offshore observations and the absence of robust evaluation models for unambiguous emplacement interpretation.

Novel Theorems on Spacetime Admitting Pseudo-W2 Curvature Tensor
This paper investigates spacetime manifolds admitting a pseudo-W2 curvature tensor. We show that a pseudo-W2 flat spacetime is an Einstein manifold and therefore has constant curvature.

Abstract Bedload transport widely occurs in natural environments and encompasses flow regimes from saltation to sheet‐flow, with markedly different fluid‐particle interaction characteristics. Understanding these mechanisms requires a numerical tool capable of capturing both the turbulence and fluid‐particle interactions, for which challenges exist due ...

The similarity between objects is a fundamental element of many learning algorithms. Most non-parametric methods take this similarity to be fixed, but much recent work has shown the advantages of learning it, in particular to exploit the local ...

Modifications of the fundamental equation of X‐ray stress analysis are proposed that allow correction of the hoop and longitudinal stresses obtained from sin2ψ measurements on samples featuring an inhomogeneous surface topography. The formalism is verified by angle‐ and energy‐dispersive measurements performed on a ferritic steel sample with ...

AES‐Debye: an accurate, efficient and scalable engine for Debye scattering calculations
AES‐Debye is an accurate, efficient and scalable engine for evaluating the Debye scattering equation that enables total scattering calculations for large atomistic models. Corrected pair‐distance binning and numerically robust accumulation suppress discretization artifacts, while parallel CPU/GPU execution enables efficient computation of scattering ...
