A Matrix‐Free, Scalable, and Robust Implicit Material Point Method

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.
ABSTRACT An implicit material point method is presented using a new dynamic relaxation solver, allowing for a simple and efficient quasi‐static formulation that may be readily implemented in existing explicit‐dynamic codes. The use of dynamic relaxation and aggregation is shown to produce an extremely robust material point method scheme, with good ...

Nonlinear Vibration Characteristic Analysis of Electric Vehicle–Road Coupling System

open access: yesInternational Journal of Mechanical System Dynamics, Volume 6, Issue 2, Page 267-281, June 2026.
ABSTRACT In‐wheel motor drive is the developing direction of automobile electrification and intelligence. However, the increased unsprung mass in in‐wheel motor‐driven electric vehicles (IWMEVs) leads to higher dynamic tire loads, thereby intensifying vehicle–road coupling interactions. To address this problem, an 11‐degree‐of‐freedom nonlinear dynamic

An Extension of a Formula of F. S. Rofe-Beketov

open access: yesMathematics
We address the following problem in this study: given a nontrivial solution, y1, of a four-coefficient Sturm–Liouville eigenvalue differential equation, construct a second solution, y2, linearly independent of y1.

Counting Degrees of Freedom: A Method Applicable From Scalars to f(Q)$f(\mathbb {Q})$ Gravity and Beyond

open access: yesFortschritte der Physik, Volume 74, Issue 6, June 2026.
ABSTRACT We present a clear, step‐by‐step method for counting degrees of freedom and identifying constraints in general field theories. This approach, grounded in the works of Einstein, Hilbert, Cartan, Kuranishi, and, more recently, Seiler, is neither Lagrangian nor Hamiltonian in nature. Instead, it applies directly to the field equations. We offer a

Topographical Features of the Lunar Surface Unveiled Through Spherical Geodesic Triangulation Analysis Method of DEM Roughness at Equal Spatial Scales

open access: yesEarth and Space Science, Volume 13, Issue 4, April 2026.
Abstract This study introduces an innovative method using equal spherical geodesic triangulation to uniformly sample the digital elevation model (DEM) of the lunar surface, ensuring an even distribution of elevation data. Utilizing spherical spline fitting, we have proposed new methods for calculating slope angles and aspects. An equilateral triangular

The Social Truth of Schopenhauer's ‘Metaphysics of Pity’: Compassion and Critical Theory

open access: yesEuropean Journal of Philosophy, Volume 34, Issue 1, Page 79-95, March 2026.
Abstract Taking Horkheimer and Adorno's account of pity in the Dialectic of Enlightenment as my starting point, I show that Schopenhauer's compassion‐based moral theory exemplifies key elements of this account. In particular, this moral theory will be shown to possess a social truth for Horkheimer and Adorno because it is an expression of a wrong ...
