Collective rearrangement at the onset of flow of a polycrystalline hexagonal columnar phase

, 2006
Creep experiments on polycrystalline surfactant hexagonal columnar phases show a power law regime, followed by a drastic fluidization before reaching a final stationary flow.

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

FEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

The Current Stress State and Seismic Hazard in the Kunlun Pass Region Following the Ms 8.1 Earthquake in 2001

Applied Sciences
The Kusaihu and Xidatan faults in the western part of the East Kunlun active fault present a miter compound relationship. The Quaternary activity of these two faults is vigorous and closely associated with potent and large earthquakes.

In situ stress state from walkaround VSP anisotropy in the Kumano basin southeast of the Kii Peninsula, Japan

Geochemistry, Geophysics, Geosystems, 2011
To reveal the stress state within the Kumano basin, which overlies the Nankai accretionary prism, we estimated seismic anisotropy from walkaround vertical seismic profiling (VSP) data recorded at Site C0009 during Integrated Ocean Drilling Program (IODP)

A Fiber Bragg Grating Borehole Deformation Sensor for Stress Measurement in Coal Mine Rock

Sensors, 2020
A borehole deformation sensor for long-term stress monitoring in coal mine rock based on optical fiber Bragg gratings (FBGs) is presented. The sensor converts borehole deformation into optical fiber strain by using four rings. For each ring, two FBGs are

In situ Measurement of Biaxial Modulus of Si Anode for Li-ion Batteries

, 2010
We report in situ measurement of biaxial moduli of a Si thin-film electrode as a function of its lithium concentration. During lithiation, biaxial compressive stress is induced in the Si film and it undergoes plastic flow. At any state-of-charge (SOC), a

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

FEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Influence of Stress Level on the Determination of In Situ Stress by DRA Method

Buildings
Obtaining reliable in situ stress field data is the precondition of the design and excavation of underground engineering. The deformation rate analysis (DRA) method based on the rock deformation memory effect is an effective method for testing in situ ...

Annealing of defects in Fe after MeV Heavy ion irradiation

, 1998
We report study of recovery dynamics, followed by in-situ resistivity measurement after 100 MeV oxygen ion irradiation, in cold rolled Fe at 300K. Scaling behavior with microstructural density and temperature of sample have been used to establish stress ...

Crack Front Segmentation and Facet Coarsening in Mixed-Mode Fracture [PDF]

, 2015
A planar crack generically segments into an array of "daughter cracks" shaped as tilted facets when loaded with both a tensile stress normal to the crack plane (mode I) and a shear stress parallel to the crack front (mode III).
