Cyclic Attractors Are Critical for Macrophage Differentiation, Heterogeneity, and Plasticity
Frontiers in Molecular Biosciences, 2022 Adaptability, heterogeneity, and plasticity are the hallmarks of macrophages. How these complex properties emerge from the molecular interactions is an open question. Thus, in this study we propose an actualized regulatory network of cytokines, signaling

A simplified creep-reverse plasticity solution method for bodies subjected to cyclic loading [PDF]
, 2004 An extension of the upper bound shakedown theorem to load histories in excess of shakedown has been applied recently to the evaluation of a ratchet limit and the varying plastic strain magnitudes associated with a varying residual stress field. Solutions

Ratchet limits for a crack in a welded pipe subjected to a cyclic temperature load an a constant mechanical load [PDF]
, 2011 This paper presents the ratchet limit analysis of a pipe with a symmetric crack in a mismatched weld by using the extended Linear Matching Method (LMM). Two loading conditions are considered: i) a cyclic temperature load and a constant internal pressure;

Residual Stresses with Time-Independent Cyclic Plasticity in Finite Element Analysis of Welded Joints [PDF]
, 2017 Due to the intense concentration of heat in a reduced area when Gas Metal Arc Welding (GMAW) is used to join mechanical components, the regions near the weld bead are subjected to severe thermal cycles.

Influence of gaseous hydrogen on plastic strain in vicinity of fatigue crack tip in Armco pure iron
MATEC Web of Conferences, 2018 A multi-scale characterisation of the crack tip plasticity has been investigated in a fatigue crack propagation under gaseous hydrogen at gas pressure of 35 MPa in a commercially pure iron, Armco iron. The dislocation structure beneath a fracture surface
