Towards a Integrated Evolutionary Model to Study Evolution of Evolution [PDF]

, 2015
International audienceVariation and Selection are the two core processes of Dar-winian Evolution. Yet, both are directly regulated by many processes that are themselves products of evolution. Microorganisms efficiently exploit this ability to dynamically

The evolution and population diversity of human-specific segmental duplications [PDF]

, 2017
Segmental duplications contribute to human evolution, adaptation and genomic instability but are often poorly characterized. We investigate the evolution, genetic variation and coding potential of human-specific segmental duplications (HSDs). We identify

Emergent Dynamics From a Position‐Based Calving Function and the Limits of a Rate‐Based Calving Function

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract A wide range of functions are currently available for simulating the calving of marine‐terminating glaciers, but there is no consensus on the best approach to represent the calving process in glacier and ice‐sheet models. Current assessments of calving functions are often crudely done by fitting functions to observed changes in terminus ...

Characterizing Dislocation Substructures in Creep‐Deformed Olivine Using Electron Channeling Contrast Imaging

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Olivine is the dominant mineral in Earth's upper mantle and therefore controls the rheological behavior of the mantle and the mechanics of plate tectonics. The constitutive laws for dislocation‐mediated deformation of olivine depend on the nature, density, and arrangements of dislocations within crystals.

Modeling of Cyclic Plastic Behavior of SN490B Steel Using Hardening Rule With the Memory Surface Concept

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT In this study, a material constitutive model based on the memory surface concept was proposed to reproduce the cyclic hardening and softening behaviors of SN490B structural steel under constant strain amplitude loading. The model incorporates combined isotropic and kinematic hardening rules, with strain‐amplitude‐dependent formulations ...

A Force‐Based Beam‐Column Element With Selective Gradient‐Inelasticity for Softening Materials in 3‐Dimensional Nonlinear Analysis

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 1, Page 26-45, January 2026.
ABSTRACT Fiber‐based beam‐column elements featuring an effective material constitutive law with softening can capture the degrading response of structural members under extreme loading. However, these elements exhibit strain localization and mesh divergence, which impedes their accuracy.
