Farm labor scarcity and its uneven impacts on crop producers in the United States

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

Noncomplete affine structures on Lie algebras of maximal class

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
Every affine structure on Lie algebra 𝔤 defines a representation of 𝔤 in aff(ℝn). If 𝔤 is a nilpotent Lie algebra provided with a complete affine structure then the corresponding representation is nilpotent.

A new system of sylvester-like matrix equations with arbitrary number of equations and unknowns over the quaternion algebra

open access: yes
In this paper, we derive some practical necessary and sufficient conditions for the existence of a solution to a new system of coupled two-sided Sylvester-like matrix equations with arbitrary number of equations and unknowns over the quaternion algebra ...

Toward a Behavioral Reserve Model in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Neurology, EarlyView.
Objective Behavioral impairment is common in amyotrophic lateral sclerosis (ALS) and strongly affects autonomy, caregiver burden, and outcomes, yet predictors of vulnerability remain unclear. We investigated whether premorbid regulatory traits and socio‐educational exposures are associated with behavioral phenotypes in ALS within a behavioral reserve ...

Research on Heat Transfer Enhancement of Spiral Grooved Tube Heat Exchangers Based on CFD and Artificial Intelligence

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Driven by the energy crisis and carbon neutrality goals, high‐efficiency heat exchange equipment has become a core demand in the industrial sector. The spiral grooved double‐pipe heat exchanger exhibits significant heat transfer enhancement advantages, yet it requires balancing heat transfer efficiency and pressure loss.
