A method for in situ SEM fracture studies of brittle materials using the double torsion technique : application to nuclear graphite [PDF]

, 2011
This work concerned the design and development of a miniature double torsion (DT) testing rig, for use inside the chamber of a scanning electron microscope, to perform in situ loading studies of brittle materials using the DT fracture mechanics specimen.

Spontaneous Uterine Leiomyoma Torsion: A Challenging Differential Diagnosis for Radiologists

European Journal of Case Reports in Internal Medicine, 2020
Uterine leiomyomas are very common gynaecological benign tumours. Spontaneous torsion of a uterine subserosal leiomyoma is a rare cause of acute lower abdominal pain and should be treated immediately with surgery.

Finding maximal torsion cosets on varieties [PDF]

, 2007
We describe a new algorithm for finding all maximal torsion cosets on varieties over $\G_m^n$. We illustrate the algorithm with some examples.The starting point for this study is the search for points on a given variety whose coordinates are roots of ...

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.

Study on initial fatigue damage of magnesium alloy under torsion and bending

Nihon Kikai Gakkai ronbunshu, 2015
Torsion and bending fatigue tests of magnesium alloy AZ31were carried out to investigate the initial damage under high cycle fatigue. The crystallographic orientation of crystals in which slip lines were occurred was analyzed by using electron back ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

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 ...

Torsion units in integral group ring of the Mathieu simple group M22 [PDF]

, 2008
We investigate the possible character values of torsion units of the normalized unit group of the integral group ring of the Mathieu sporadic group M22.

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Case Report: Adolescent epididymal cysts: three management approaches including a rare synchronous epididymal cyst and testicular torsion

Frontiers in Surgery
IntroductionEpididymal cysts are common benign lesions that typically present as painless scrotal masses. They predominantly occur in adult males but can also be found in adolescents, albeit with a higher likelihood of being overlooked at this age.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
