Sparse Minimum Redundancy Maximum Relevance for Feature Selection

open access: yesScandinavian Journal of Statistics, Volume 53, Issue 3, Page 1134-1151, September 2026.
ABSTRACT We propose a feature screening method that integrates both feature–feature and feature–target relationships. Inactive features are identified via a penalized minimum Redundancy Maximum Relevance (mRMR) procedure, which is the continuous version of the classical mRMR penalized by a non‐convex regularizer, and where the parameters estimated as ...

Adaptive Matrix‐Free Simulations of Fluid‐Filled Phase‐Field Fractures With Fixed‐Stress Coupling and Fracture‐Width Computation

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 15, 15 August 2026.
ABSTRACT Fluid‐filled phase‐field fracture simulations require robust, scalable solvers that can handle strongly nonlinear, non‐smooth mechanics and tightly coupled flow on locally refined meshes. In this work, we develop an adaptive finite element framework for quasi‐static, fluid‐filled phase‐field fractures that combines semi‐smooth Newton methods ...

Time‐resolved PET imaging using a joint dynamic reconstruction and motion estimation framework (DREME‐PET)

open access: yesMedical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Positron emission tomography (PET) plays a critical role in image‐guided radiotherapy by enabling accurate tumor localization and contouring. To account for respiration‐induced anatomical motion, time‐resolved PET imaging is highly desirable, as it captures dynamic anatomical variations to facilitate both disease diagnosis and ...

The Weak Core, Partition‐Based Universal Stability, and Their Risk Associations Through A Partial Order

open access: yesNaval Research Logistics (NRL), Volume 73, Issue 5, Page 810-835, August 2026.
ABSTRACT We are concerned with the stability of a transferable‐utility cooperative (TU) game. First, the concept of core can be weakened so that the blocking of changes is limited to only those with multilateral backings. This principle of consensual blocking, as well as the traditional core‐defining one of unilateral blocking and one straddling in ...

Assessing the Effects of Biodiesel Production on Sustainability: A Bayesian Two‐Stage Data Envelopment Analysis Approach

open access: yesSustainable Development, Volume 34, Issue 4, Page 5648-5668, August 2026.
ABSTRACT Sustainable development transforms production systems, requiring integrated environmental, social, and economic strategies. Energy systems are key agro‐industrial supply chains in developing countries. Brazil's soybean supply chain impacts Gross Domestic Product, mainly through exports.

Estimating Wind‐Power Capacity Time Series From Production Data Using a Power Curve Model and Quadratic Optimization

open access: yesWind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT Accurate, time‐resolved installed capacity data are crucial for forecasting and analysing wind‐power production. The time series of installed capacity is often only approximately known in regions with rapid wind power development. Public wind power databases may only be updated yearly and installation dates may not be differentiated within ...
