A novel indirect optical method for rock stress measurement using micro-deformation field analysis

Journal of Rock Mechanics and Geotechnical Engineering
Stress measurement plays a crucial role in geomechanics and rock engineering, especially for the design and construction of large-scale rock projects.

Out-of-plane bending stress intensity factor analysis of cracks in a strip using single-element strain gage

Nihon Kikai Gakkai ronbunshu, 2023
In recent years, the authors have developed a dedicated strain gage (hereafter referred to as a K-value gage) and an analysis method that can analyze the stress intensity factor of a crack with a single element.

Stress-Strain Measurements and Viscoelastic Response of Blood Vessels Cryopreserved by Vitrification [PDF]

Annals of Biomedical Engineering, 2007
To gain increased insight into thermo-mechanical phenomena during cryopreservation, tensile stress relaxation experiments were conducted on vitrified blood vessels (vitreous in Latin means Glassy), and the results compared with various viscoelastic models.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

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.

Influence of strain measurement methods on crack initiation and crack damage thresholds of shale

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
The crack initiation stress (σ ci) and crack damage stress (σ cd) are two important stress thresholds for describing the progressive failure process of rocks.

Young-Measure approximations for elastodynamics with non-monotone stress-strain relations [PDF]

ESAIM: Mathematical Modelling and Numerical Analysis, 2004
Summary: Microstructures in phase-transitions of alloys are modeled by the energy minimization of a nonconvex energy density \(\phi\). Their time-evolution leads to a nonlinear wave equation \(u_{tt}=\text{div}\;S(Du)\) with the non-monotone stress-strain relation \(S=D\phi\) plus proper boundary and initial conditions. This hyperbolic-elliptic initial-

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Compression stress-strain curve of rammed earth: Measuring and modelling

Results in Engineering, 2023
This research article is about a study on the mechanical behavior of rammed earth under compression stress. The main purpose is to establish a simple stress-strain model for rammed earth. The tested rammed earthen materials are made of various local materials with different grain-size curves and grain shapes.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
