Adaptive Finite Element Prediction of Fatigue Life and Crack Path in 2D Structural Components

Metals, 2020
The existence of a hole near a growing fatigue crack can cause the crack trajectory to deviate. Unless the hole is too close to the crack, the crack is arrested at the edge of the hole and does not progress further.

Development of a fretting-fatigue mapping concept: The effect of material properties and surface treatments [PDF]

, 2009
Fretting-fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic failure of the contacting components.

Fretting Fatigue Behavior under Tension–Bending Mixed-Mode Loading

Applied Sciences
The mixed-mode loading fretting fatigue caused by the complex geometry of components and combinations of boundary conditions is a common failure mechanism in engineering components, which can dramatically reduce fatigue life. In this paper, a cylinder-on-

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
