Gruss inequality for some types of positive linear maps [PDF]

open access: yes, 2014
Assuming a unitarily invariant norm $|||\cdot|||$ is given on a two-sided ideal of bounded linear operators acting on a separable Hilbert space, it induces some unitarily invariant norms $|||\cdot|||$ on matrix algebras $\mathcal{M}_n$ for all finite ...

Impact of Trap Depth on the Steady‐State and Transient Photoluminescence in Halide Perovskite Films

open access: yesAdvanced Energy Materials, EarlyView.
The presence of shallow traps in halide perovskites is frequently postulated by density functional theory calculations. This review studies the implications of recombination‐active shallow traps on steady‐state and transient recombination kinetics. How to identify shallow traps and how the depth of the traps and their density are reflected in different

Machine Learning for Accelerating Energy Materials Discovery: Bridging Quantum Accuracy with Computational Efficiency

open access: yesAdvanced Energy Materials, EarlyView.
This perspective highlights how machine learning accelerates sustainable energy materials discovery by integrating quantum‐accurate interatomic potentials with property prediction frameworks. The evolution from statistical methods to physics‐informed neural networks is examined, showcasing applications across batteries, catalysts, and photovoltaics ...

Bayesian inference for linear models subject to linear inequality constraints

open access: yes, 1996
The normal linear model, with sign or other linear inequality constraints on its coefficients, arises very commonly in many scientific applications. Given inequality constraints Bayesian inference is much simpler than classical inference, but standard ...

The Financial Status and Local Credit Market Conditions of U.S. Farms Engaged in Multiple Borrowing

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Agricultural producers often borrow from multiple lenders, raising concerns about credit risk and monitoring. We construct detailed farm‐level measures of how debt is distributed across lenders and examine how farm financial status and the physical presence of local lenders are linked to this practice.

Gaussian processes with linear operator inequality constraints

open access: yes, 2019
This paper presents an approach for constrained Gaussian Process (GP) regression where we assume that a set of linear transformations of the process are bounded.

2023–2027 CAP First Pillar Reform and Livestock Sector: Production and Economic Impacts on Italian Specialized Dairy Cattle Farms

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The present study uses an agroeconomic supply model to assess the impacts of 2023–2027 CAP on Italian specialized dairy cattle farms. The model considers the voluntary choice of Eco‐Scheme 1, specifically addressed to livestock farms, through the implementation of binary variables.

Climate Change Agricultural Comparative Advantage and the US Trade Balance

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Current science indicates that warming and elevated atmospheric CO2 will have ambiguous results for crop productivity depending on crop type and geographic location, whereas increased heat stress makes livestock and human labor less productive.
