Monolithic Newton‐Multigrid Finite Element Methods for the Simulation of Thixoviscoplastic Flows
International Journal for Numerical Methods in Fluids, Volume 97, Issue 4, Page 565-604, April 2025.ABSTRACT In this paper, we shall be concerned with the development, application, and numerical analysis of the monolithic Newton‐Multigrid finite element method (FEM) to simulate thixoviscoplastic (TVP) flows. We demonstrate the importance of robustness and efficiency of Newton‐Multigrid FEM solver for obtaining accurate solutions.

Can ChatGPT Implement Finite Element Models for Geotechnical Engineering Applications?
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 6, Page 1747-1766, 25 April 2025.ABSTRACT This study assesses the capability of ChatGPT to generate finite element code for geotechnical engineering applications from a set of prompts. We tested three different initial boundary value problems using a hydro‐mechanically coupled formulation for unsaturated soils, including the dissipation of excess pore water pressure through fluid mass

Foundations of Ghost Stability
Fortschritte der Physik, Volume 73, Issue 4, April 2025.Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

How to Define, Use, and Interpret Pagel's λ$$ \lambda $$ (Lambda) in Ecology and Evolution
Global Ecology and Biogeography, Volume 34, Issue 4, April 2025.ABSTRACT Aim Pagel's λ$$ \lambda $$ (lambda) is a useful tool in ecology and evolution for describing trait evolution, imputing missing species' data, and generalising ecological relationships beyond their study system. Here, we review the various applications and interpretations of λ$$ \lambda $$, highlight common misconceptions, and show how ...

Summary characteristics for multivariate function‐valued spatial point process attributes
International Statistical Review, Volume 93, Issue 1, Page 150-178, April 2025.Summary Prompted by modern technologies in data acquisition, the statistical analysis of spatially distributed function‐valued quantities has attracted a lot of attention in recent years. In particular, combinations of functional variables and spatial point processes yield a highly challenging instance of such modern spatial data applications.

Measure‐valued processes for energy markets
Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

The fundamental theorem of asset pricing with and without transaction costs
Mathematical Finance, Volume 35, Issue 2, Page 567-609, April 2025.Abstract We prove a version of the fundamental theorem of asset pricing (FTAP) in continuous time that is based on the strict no‐arbitrage condition and that is applicable to both frictionless markets and markets with proportional transaction costs. We consider a market with a single risky asset whose ask price process is higher than or equal to its ...

Nursing and Pluralism: The Work of Michel Serres
Nursing Philosophy, Volume 26, Issue 2, April 2025.ABSTRACT Nursing theory should reflect the pluralism inherent in nursing practice. Nurses routinely enact different kinds of knowledge in combination to achieve good nursing care. Nursing theoretical and philosophical literature includes many attempts to engage with epistemological pluralism.
