A Peridynamic Framework for Modeling Progressive Failure in Porous Sandstone Indentation

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A state‐based peridynamic model is proposed to simulate the failure mechanisms in porous rocks, using Bentheim sandstone as a specific example. Experimental observations reveal a transition from brittle to ductile failure under increasing triaxial compression. This behavior is attributed to pore compaction. The peridynamic model is enhanced to

Roots of resilience: Assessing child and adolescent nature connectivity in the Mediterranean Region of Murcia (Spain)

open access: yesPeople and Nature, EarlyView.
Abstract Children today spend less time outdoors than previous generations, with potential consequences for health, learning and pro‐environmental attitudes. We assessed children's connection with and exposure to nature in a Mediterranean setting using the Nature Connection and Experience Index (NCEI), a composite measure that integrates an affective ...

Peridynamics with a Cube‐Shaped Neighborhood

open access: yesPAMM, Volume 26, Issue 1, March 2026.
ABSTRACT This paper investigates the effects of cube‐shaped neighborhoods in peridynamic theory as an alternative to the traditional spherical neighborhoods. We examine how different neighborhood geometries influence the behavior of various peridynamic formulations, including bond‐based models, state‐based formulations, and correspondence methods.

From Douyin Shop to TikTok Shop: The Platformized Supply Chain, Spatialized Business Model, and Regional Partnership in Cross‐Border e‐Commerce

open access: yesPolicy &Internet, Volume 18, Issue 1, March 2026.
ABSTRACT This article investigates how TikTok Shop reproduces the e‐commerce model of Douyin Shop against a backdrop of divergent regulatory challenges and geopolitical distrust. One of the strategic changes we observe in TikTok Shop is the shift of consumer goods suppliers from local merchants to China‐based sellers.

Neumann Homogenization via Integro-Differential Operators, Part 2: singular gradient dependence

open access: yes, 2018
We continue the program initiated in a previous work, of applying integro-differential methods to Neumann Homogenization problems. We target the case of linear periodic equations with a singular drift, which includes (with some regularity assumptions ...

Integrating Urban Expansion and Flood Risk: A Spatial Assessment of Impervious Surface Growth and Floodplain Exposure in Mecklenburg County (2011–2021)

open access: yesWorld Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Urban expansion significantly impacts flood risk, particularly in rapidly growing areas where impervious surfaces exacerbate surface runoff. This study examines spatial patterns of urban growth and their effects on flood exposure in Mecklenburg County, North Carolina, from 2011 to 2021.
