Tangent Blow‐Ups for Processing Non‐Manifold Geometry
Computer Graphics Forum, EarlyView.Abstract Many geometry processing pipelines implicitly assume their input data is a manifold, or is sampled from one, with a unique tangent plane at every point. Geometric data, however, routinely contains sharp features like edges, corners, self‐intersections, branching junctions, and other singularities, rendering standard methods ill‐defined at ...

A Review of Seismic Anisotropy
, 2016 Lithosphere is usually modeled as a layered isotropic medium. However, in reality, upper mantle is anisotropic as evidenced by the azimuthal dependence of P and S wave propagation speed. Probable causes of the observed seismic wave propagation anisotropy include the aligned crystal structure of minerals, aligned cracks and fractures. This anisotropy in

Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment
Terra Nova, EarlyView.ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Crustal Seismic Anisotropy in Shandong
DEStech Transactions on Materials Science and Engineering, 2017 Based on the seismic data of near-field source from Shandong Seismic Network, the study obtained the shear-wave splitting parameters from multiple stations. The results show that dominant directions of polarizations of fast shear-waves reflect the spatial distribution characteristics of tectonic stress in this area, CHD and LIS stations show 2 dominant

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities
Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2618-2633, September 2026.ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such

Multicontinuum Homogenization for Poroelasticity Model
International Journal for Numerical Methods in Fluids, Volume 98, Issue 9, Page 1035-1060, September 2026.This work derives a generalized multicontinuum poroelasticity model using the multicontinuum homogenization method to enable accurate coarse‐grid simulations of coupled flow–mechanics processes in highly heterogeneous porous media. Coupled constraint cell problems are formulated, and the corresponding multicontinuum equations are rigorously derived ...

ECOMAN: an open-source package for geodynamic and seismological modelling of mechanical anisotropy [PDF]
Solid EarthMechanical anisotropy related to rock fabrics is a proxy for constraining the Earth's deformation patterns. However, the forward and inverse modelling of mechanical anisotropy in 3D large-scale domains has been traditionally hampered by the intensive ...

Macromolecular Theory and Simulations, Volume 35, Issue 5, September 2026.Coarse‐grained molecular dynamics simulations reveal how crosslinking governs deformation and viscoelasticity in rubber networks. Crosslinks promote molecular‐chain orientation and preferentially carry deformation stress. Increasing crosslink density slows stress relaxation, lowers the loss tangent peak, and raises the equilibrium modulus, while stress
