Finite-strain formulation and FE implementation of a constitutive model for powder compaction
, 2014 A finite-strain formulation is developed, implemented and tested for a constitutive model capable of describing the transition from granular to fully dense state during cold forming of ceramic powder.

The ocean returns: Mapping a mercurial Anthropocean [PDF]
Social Science Information, 2018 Humans have dumped ‘stuff’ in oceans in a particularly concentrated way since the Industrial Revolution, the effects of which we now note as evidence of the Anthropocene – or the Anthropocean. In this article, I consider what the oceans now return to us in the form of pollution.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Bloodstream infections due to repeated vascular access (VA) puncture and circuit connections remain major concerns in hemodialysis. Therefore, we examined current practices for glove, disinfectant, and personal protective equipment (PPE) use according to VA type in national university hospitals in Japan.

Closed form solution of the return mapping algorithm in elastoplasticity [PDF]
, 2017 In the present work a return mapping algorithm is discussed for small strain elastoplasticity boundary value problems with an exact closed form solution of the local constitutive equations.

Cycling chaotic attractors in two models for dynamics with invariant subspaces [PDF]
, 2004 Nonergodic attractors can robustly appear in symmetric systems as structurally stable cycles between saddle-type invariant sets. These saddles may be chaotic giving rise to 'cycling chaos'.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

, 2020 We are concerned with the mathematical modeling of the polarization process in ferroelectric media. We assume that this dissipative process is governed by two constitutive functions, which are the free energy function and the dissipation function.
