Analysis of biaxial proportional low-cycle fatigue and biaxial accumulative plasticity of hull inclined-crack plate

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2022
Fracture induced failure of plates in hull structures subjected to in-plane biaxial low-cycle fatigue loading are generally a combination of accumulative plasticity and biaxial low-cycle fatigue damage.

The effect of quenching and defects size on the HCF behaviour of Boron steel [PDF]

open access: yes, 2014
This work investigates the effect of natural and artificial surface defects and quenching on the fatigue strength of a Boron steel (22MnB5). A vast experimental campaign has been undertaken to study the high cycle fatigue behaviour and more specifically ...

High-Temperature Low Cycle Fatigue Life Prediction and Experimental Research of Pre-Tightened Bolts

open access: yesMetals, 2018
Bolted connections are widely used in various mechanical structures due to their superior fastening properties. However, vibration and fatigue loads in the structure are likely to cause fatigue failure of the bolted joints, especially those under high ...

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

open access: yesFEBS 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

open access: yesFEBS 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.

Fatigue-creep behaviors of Ni–Fe based superalloy under various testing conditions

open access: yesJournal of Materials Research and Technology, 2021
The fatigue-creep properties of Ni–Fe based superalloy with varying strain amplitude, temperature and holding duration are studied in ambient air. The results demonstrated that the number of cycles decreases greatly with increasing strain amplitude from ...

Validity of a Wearable Digital Insole for Assessing Gait ON and OFF in Parkinson's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Gait impairment is a distinctive symptom of Parkinson's disease that negatively impact mobility. We assessed the validity of wearable digital insoles against a validated reference gait analysis system for measuring select gait characteristics in patients with Parkinson's disease. Methods A comparative analysis between digital insoles

Multiaxial Low Cycle Fatigue Life Prediction under N onproportional Loading [PDF]

open access: yes, 2001
This paper studies the effect of nonproportional straining on tension-torsion low cycle fatigue lives of two types of materials. Extensive low cycle fatigue tests under 14 proportional and non-proportional strain paths were carried out using Type 304 ...
