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.

The Stress Singularity in a Stepped Bar Under Impact Torsion
JSME international journal. Ser. 1, Solid mechanics, strength of materials, 1989 An impact torsion problem for a steppedbar composed of two semi-infinite bars bonded completely at each end is investigated. A stress singularity occurs at the corner of the bars. Therefore the stress analysis proceeds considering this stress singularity by making use of the series expansion technique, and the problems are reduced to an infinite set of

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Experimental investigation of torsional vibration isolation using Magneto Rheological Elastomer
MATEC Web of Conferences, 2018 Rotating systems suffer from lateral and torsional vibrations which have detrimental effect on the roto-dynamic performance. Many available technologies such as vibration isolators and vibration absorbers deal with the torsional vibrations to a certain ...
