Space‐Time FEM Solution of Dynamic Contact Problem With Discontinuous Velocity for Multiple Impact of Deformed Bar Using PDAS Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A class of one‐dimensional impact and dynamic contact problems taking into account non‐smooth velocities is studied. The new space‐time finite element approximation of dynamic variational inequalities is suggested. The non‐smooth solution for the impact of an obstacle by an elastic bar and its energy conservation under persistency conditions ...

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.

Ellipsoid‐Based Interval‐Type Uncertainty Model Updating Based on Riemannian Manifold and Gaussian Process Model

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern engineering systems require advanced uncertainty‐aware model updating methods that address parameter correlations beyond conventional interval analysis. This paper proposes a novel framework integrating Riemannian manifold theory with Gaussian Process Regression (GPR) for systems governed by Symmetric Positive‐Definite (SPD) matrix ...

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

Naval Research Logistics (NRL), EarlyView.
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 ...

Brokering Localization: Country‐Based Pooled Funds in Humanitarian Assistance

Public Administration and Development, EarlyView.
ABSTRACT This article analyzes Country‐Based Pooled Funds (CBPFs) to identify types of brokerage models and their effects on localization. CBPFs are intermediaries in the aid chain connecting donors to implementers such as the United Nations, international non‐governmental organizations (INGOs) and national NGOs (NNGOs). This paper analyzes four of the

More than proteins for empty stomachs: Wild meat in the BaTonga food system

People and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.

From commons to commoning as resistance efforts to blue injustice: A sociohistorical and ethnographical approach

People and Nature, EarlyView.
Abstract Over the last 20 years, collaborative efforts have emerged with the intention of going beyond the pure capitalist economy, seeking to generate transformative community‐based changes that guarantee blue equity, fair distribution and well‐being.

Arakelov Inequalities for a Family of Surfaces Fibered by Curves

Mathematics
The numerical invariants of a variation of Hodge structure over a smooth quasi-projective variety are a measure of complexity for the global twisting of the limit-mixed Hodge structure when it degenerates.

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, EarlyView.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...
