Determination of Stress Intensity Factors and J integral based on Digital Image Correlation
Fracture and Structural Integrity, 2019 Digital image correlation (DIC) is a technique in experimental mechanics to acquire full-field measurement data of displacements and deformations from the surface of specimens or components.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Engineering Transactions, 2014 Recently, much attention has been paid to TRIP steel since it indicates both high ductility and strength by strain induced martensitic transformation. This transformation allows TRIP steel to offer larger energy absorption than other steel at the same ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Calculation and Analysis of Crack Stress Intensity Factor and
Jixie chuandong, 2020 The distribution of stress intensity factor and J integral of helical gear with three-dimensional crack under different initial crack parameters is studied. The finite element software is used to analyze the helical gear with initial crack.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Fracture and Structural Integrity, 2015 In many engineering applications special requirements are directed to a material's fracture behavior and the prediction of crack paths. Especially if the material exhibits anisotropic elastic properties or fracture toughnesses, e.g.

Journal of Engineering, 2005 Cracks may appear in structures due to manufacturing processes and some time are appeared in the structure product from casting, these struetures may be used but in the life less than the design life according to crack propagation on it.

Journal of High Energy Physics, 2020 We recast the joint J T ¯ $$ J\overline{T} $$ , T J ¯ $$ T\overline{J} $$ and T T ¯ $$ T\overline{T} $$ deformations as coupling the original theory to a mixture of topological gravity and gauge theory.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
