Journal of Agricultural Economics, Volume 77, Issue 2, Page 356-382, June 2026.ABSTRACT Most research questions in agricultural and applied economics are causal in nature: they study how changes in one or more variables (such as policies, prices or weather) affect one or more other variables (e.g., income, crop yields or pollution).

Random permutations without macroscopic cycles [PDF]
, 2020 We consider uniform random permutations of length n conditioned to have no cyclelonger than nβ with 0 < β < 1, in the limit of large n. Since in unconstrained uniform random permutations most of the indices are in cycles of macroscopic length, this is a ...

Do Alopecia Areata and Hair Colour Have a Shared Genetic Component?
Experimental Dermatology, Volume 35, Issue 6, June 2026.The aim of our study was to determine whether hair colour and the risk of developing alopecia areata (AA) share a genetic basis. While we found no evidence for a broadly shared polygenic background, our analyses revealed suggestive evidence that genetically predicted blond hair is associated with a reduced risk of AA. ABSTRACT Alopecia areata (AA) is a

Effect of placing a diffuser around a wind turbine
, 2000 An actuator disc CFD model of the flow through a wind turbine in a diffuser is developed and validated. Further, it is shown theoretically from a 1D analysis that the Betz limit can be exceeded by a factor proportional to the relative increase in mass ...

Freshwater Biology, Volume 71, Issue 6, June 2026.ABSTRACT Natural populations are increasingly exposed to multiple stressors, such as chemical pollution and climate‐change‐driven heatwaves. While it has become clear that we need to account for stressor interactions, it is less well understood how sequential exposure to different stressors influences organismal responses as well as their potential for

How Race‐Conscious (Vs. Colorblind) Cues Impact White Americans’ Inter‐ and Intraracial Interactions
Journal of Social Issues, Volume 82, Issue 2, June 2026.ABSTRACT Although both inter‐ and intraracial conversations about race are necessary for combating racism, discrepancies in people's racial ideologies may hinder these discussions. We conducted three experiments (N = 1529) to test how White American adults on Prolific (Studies 1 and 2) and White American college students (Study 3) anticipate a ...

The Betz limit sets a theoretical upper limit for the energy efficiency of turbines with a maximum power coefficient of 16/27. Betz's theory is precise and based on the calculation of kinetic energy. However, if the potential energy is taken into account the theoretical energy efficiency of a turbine can be higher.

Neuropathology and Applied Neurobiology, Volume 52, Issue 3, June 2026.KIF1A‐associated neurological disorder (KAND) is a rare hereditary condition caused by KIF1A variants, affecting axonal transport and presenting with a wide clinical spectrum, including hereditary spastic paraplegia. This case of childhood‐onset KAND reveals FTLD‐TDP43 with motor neuron disease pathology emerging late in the disease course, suggesting ...

Gibbs measures with double stochastic integrals on a path space
, 2007 We investigate Gibbs measures relative to Brownian motion in the case when the interaction energy is given by a double stochastic integral. In the case when the double stochastic integral is originating from the Pauli-Fierz model in nonrelativistic ...

Nursing &Health Sciences, Volume 28, Issue 2, June 2026.ABSTRACT Ophthalmic surgeries pose infection risks. Traditional control methods rely on manual monitoring, creating a need for more precise, data‐driven nursing models. This study evaluated the effectiveness of real‐time data analysis in improving ophthalmic infection prevention and control outcomes.
