Ban Glyphosate—Does It Affect the Swedish Farmers' Willingness to Grow Cover Crops?

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The cultivation of cover crops is one of the new Eco‐scheme practices introduced in Sweden. This study examines how the design of policy attributes of these schemes influences farmers' willingness to grow cover crops on arable land, with particular focus on the potential impact of a glyphosate ban.

B-spline polynomials models for analyzing growth patterns of Guzerat young bulls in field performance tests [PDF]

Animal Bioscience
Objective The aim of this study was to identify suitable polynomial regression for modeling the average growth trajectory and to estimate the relative development of the rib eye area, scrotal circumference, and morphometric measurements of Guzerat young ...

Unpacking the Farmland Capitalization Effect of Ethanol Establishment

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We unpack the impact of expansions in ethanol production—as measured by proximity to newly constructed ethanol plants and capacity expansions—on farmland values using land transaction data from Kansas in combination with modern causal inference techniques.

Gibbs sampling for Bayesian P-splines

P-splines provide a flexible setting for modeling nonlinear model components based on a discretized penalty structure with a relatively simple computational backbone. Under a Bayesian inferential framework based on Markov chain Monte Carlo, estimates of model coefficients in P-splines models are typically obtained by means of Metropolis-type algorithms.

Crop Insurance Design and On‐Farm Risk Adaptation

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The United States spends billions annually on crop insurance premium subsidies, yet the prevailing distance‐based guarantee design unintentionally rewards risk‐taking by linking subsidies to yield variability. We consider a simple redesign: define guarantees in terms of probability so that coverage reflects a consistent likelihood of indemnity.

Impact of Abdominoperineal Resection on Postoperative Male Sexual Function After Minimally Invasive Rectal Cancer Surgery: A Subgroup Analysis From the LANDMARC Study

Annals of Gastroenterological Surgery, EarlyView.
Abdominoperineal resection (APR) after minimally invasive rectal cancer surgery was associated with significantly higher rates of erectile and early ejaculatory dysfunction compared with anal‐sparing surgery. Although ejaculatory function showed partial recovery over time, erectile dysfunction persisted up to 12 months postoperatively.

Explaining the Origin of Negative Poisson's Ratio in Amorphous Networks With Machine Learning

Advanced Intelligent Discovery, EarlyView.
This review summarizes how machine learning (ML) breaks the “vicious cycle” in designing auxetic amorphous networks. By transitioning from traditional “black‐box” optimization to an interpretable “AI‐Physics” closed‐loop paradigm, ML is shown to not only discover highly optimized structures—such as all‐convex polygon networks—but also unveil hidden ...

Extending Battery Usage Time of a Heavy‐Duty Mecanum‐Wheeled Autonomous Electric Vehicle Used in Iron–Steel Industry by Considering Wheel Slippage

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
It is a fact that slippage causes tracking errors in both longitudinal and lateral directions which results to have less travel distance in tracking a reference trajectory. Less travel distance means having energy loss of the battery and carrying loads less than planned.
