Interruption of the strain rate sensitivity of metals at the necking onset

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2018
In this work, the interaction between the necking onset and the strain rate sensitivity in tensile tests by Split Hopkinson Tensile Bar (SHTB) is investigated.

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Influence of lithium concentration on microstructure and nanomechanical characterization of plastically deformed lightweight Mg-Li-Zn-Ca alloys

Journal of Alloys and Metallurgical Systems
Plastic deformation of MgxLi1Zn0.5Ca (x = 0, 4, 8, 11) alloys after thermomechanical treatment were explored in this investigation. Nanomechanical testing and microstructural characterization were conducted on as-cast alloys as well as those rolled at ...

Strain-rate sensitivity of high-entropy alloys and its significance in deformation

Materials Research Letters, 2019
Strain-rate dependence in face centered cubic high entropy alloys still remains controversial despite extensive efforts on this topic. Strain-rate sensitivity reflects underlying thermally-activated deformation and the controversy boils down to the ...

Associations of Sleep and Shift Work With Osteoarthritis Risk

Arthritis Care &Research, EarlyView.
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships among circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000–person cohort, we evaluated associations among sleep duration, sleeplessness/insomnia, and shift
