Peasant Movements and the Fourth Transformation in Mexico: What Does the Theory of Collective Empowerment Tell Us?

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT This article examines peasant and Indigenous movements in Mexico since Morena's rise to power in 2018 through the lens of collective empowerment theory, a theory of political‐cultural formation. Beyond offering an empirical assessment, the theory is refined and formalized through an analysis of these movements and their relationship to ...

A Novel Flexible Multibody System Dynamic Analysis Platform of Tower Crane

open access: yesMachines
Current research on tower crane control lacks high-fidelity models and fails to account for the coupling effects between the tower crane structure and the hoisting and luffing systems.

Shaping Arab Identity Through the Beautiful Game: A Heterotopic Analysis of the 2022 World Cup

open access: yesStudies in Ethnicity and Nationalism, EarlyView.
ABSTRACT This study examines how the 2022 FIFA World Cup in Qatar functioned as a heterotopic space through which Middle Eastern and North African (MENA) identities were publicly articulated, negotiated and made visible. Drawing on Foucault's notion of heterotopia and Lefebvre's understanding of space as socially produced, the paper approaches the ...

Dynamic Modeling and Analysis of Rigid-Flexible Coupled Unfolding Mechanisms Under Transient Actuation

open access: yesApplied Sciences
Transient mechanisms are increasingly applied in fields such as high-speed aircraft, super high-speed trains, and underwater robots. However, in high-speed motion, large inertial forces are inevitably generated, which can easily lead to elastic ...

Human Herpesvirus 8 Causes a Wide Spectrum of Disease in Liver Transplant Recipients and May be Donor Derived: Case Series and Systematic Review of an Emerging Challenge

open access: yesTransplant Infectious Disease, EarlyView.
Among 135 cases of post‐liver transplant HHV8 disease (4 from NSW), presentations varied, and mortality was high (44%). Donor screening was rare, and donor‐derived infection was suspected in 33%. Survival improved with mTORi, reduced immunosuppression, chemotherapy, and, for non‐KS disease, donor screening. ABSTRACT Background Human herpesvirus 8 (HHV8)

Global Graph Surrogates and Neural Graph Elements for Computational Mechanics

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Machine learning surrogates are increasingly used to accelerate physics‐based simulations by predicting full‐field responses at a fraction of the computational cost. In this contribution, we present two complementary graph‐based approaches for surrogate modelling in computational mechanics.

A Spike‐Based Graph Surrogate for Modeling Finite Element Structures

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The use of Artificial Intelligence (AI) in structural mechanics has grown substantially in the recent years, with diverse applications ranging from constitutive laws and Gauss‐point‐level enhancements to the complete replacement of classical Finite Element Methods (FEM) with surrogate models.

Sphingosine‐1‐Phosphate Attenuates LPS‐Induced Inflammatory Cardiac Injury in Association With RASGRP1–S100A9–NLRP3 Signaling

open access: yesDrug Development Research, Volume 87, Issue 7, November 2026.
ABSTRACT Lipopolysaccharide (LPS) induces endotoxemia‐associated inflammatory cardiac injury rather than classical viral or autoimmune myocarditis. Sphingosine‐1‐phosphate (S1P) regulates cardiovascular and immune responses, predominantly through S1P receptors, but whether it also modulates macrophage‐associated inflammatory signaling during LPS ...

Research on the Dynamic Modeling of Rigid–Flexible Composite Spacecraft Under Fixed Constraints Based on the ANCF

open access: yesAerospace
Dynamically modeling the flexible characteristics of large-scale jointed composite spacecraft is challenging. In this study, a dynamic modeling method for rigid–flexible composite spacecraft is proposed based on the absolute nodal coordinate formulation (

Edge‐Based Discretizations on Triangulations in Any Dimension, With Special Attention to Four‐Dimensional Space

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 10, Page 1143-1164, October 2026.
This article provides important geometric formulas for node‐centered, edge‐based schemes in any number of dimensions. These formulas are noteworthy, as they do not require the explicit formation of dual regions. We prove several key geometric results, with a particular focus on the four‐dimensional case, due to potential space‐time applications ...
