Sensitivity analysis of the GTN damage parameters at different temperature for dynamic fracture propagation in X70 pipeline steel using neural network

open access: yesFracture and Structural Integrity, 2021
In this paper, the initial and maximum load was studied using the Finite Element Modeling (FEM) analysis during impact testing (CVN) of pipeline X70 steel.

Sestrins are evolutionarily conserved mediators of exercise benefits. [PDF]

open access: yes, 2020
Exercise is among the most effective interventions for age-associated mobility decline and metabolic dysregulation. Although long-term endurance exercise promotes insulin sensitivity and expands respiratory capacity, genetic components and pathways ...

Age‐Associated Dysregulation of Postsynaptic Mitochondria Perturbs Reinnervation Kinetics

open access: yesAging Cell, Volume 25, Issue 1, January 2026.
We show that aging results in postsynaptic mitochondrial loss at the neuromuscular junction and impaired muscle reinnervation. In vivo CRISPR knockout of mitochondrial genes, CHCHD10 and CHCHD2, in young muscles led to fragmented endplates, aberrant innervation, and impaired transcriptional maturation of sub‐synaptic myonuclei during regeneration ...

Investigation on hydrogen embrittlement and failure characteristics of Zr-4 cladding based on the GTN method

open access: yesNuclear Materials and Energy, 2023
Based on the classical Gursone-Tvergaarde-Needleman (GTN) method, a theoretical model was developed and applied to predict the mechanical behavior and fracture characteristics of hydrogenated zirconium cladding.

Adipocytokine levels mark endothelial function in normotensive individuals [PDF]

open access: yes, 2012
BACKGROUND: Endothelial dysfunction is an independent risk factor for cardiovascular events. Inflammatory mediators released by the adipose tissue can lead to local insulin resistance and endothelial dysfunction.

Pyrolysis of Onion Peel Waste: Investigation of Comprehensive Pyrolysis Index, Reaction Mechanism, Kinetic, and Thermodynamic Properties Using TGA Analysis

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
The rising demand for onion production results in significant waste, harming the environment. Onion waste is unsuitable for animal feed and difficult to dispose of due to its strong odor and potential for phytopathogen growth. Pyrolysis is a promising method for repurposing food waste, requiring minimal infrastructure and offering rapid processing and ...

Numerical simulation and experimental investigation of ductile fracture in SPIF using modified GTN model

open access: yesMATEC Web of Conferences, 2015
Incremental sheet forming (ISF) is a relatively new flexible forming process with excellent adaptability to CNC milling machines due to the fact that it does not require any high capacity presses or dies of a specific shape and this makes the process ...

Damage evolution of 7075 aluminum alloy basing the Gurson Tvergaard Needleman model under high temperature conditions

open access: yesJournal of Materials Research and Technology, 2022
Based on the Gurson-Tvergaard-Needleman (GTN) damage model, the damage evolution and ductile fracture of 7075 aluminum alloy sheets during the tensile process were predicted. First, the true stress–strain curve and micro morphology of 7075 aluminum alloy

ROS‐Scavenging Multifunctional Microneedle Patch Facilitating Wound Healing

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 31, December 8, 2025.
A reactive oxygen species (ROS) scavenging and immunomodulatory microneedle patch based on hyaluronic acid methacrylate (HaMA) and Flightless I (Flii)‐siRNA‐laden arginine functionalized poly (β‐amino ester)/alginate particles is developed for chronic wound healing applications.
