Bar impact instruments, such as the (split) Hopkinson bars and direct bars, measure blast/impact waves or mechanical properties of materials at high strain rates. To effectively use it is essential to know (i) elastic bar, (ii) correction factor measured strain, (iii) information on velocity. This paper presents a graphic-user-interface (GUI) program prepared for solving these fundamental issue...

The vaginal microbiome plays an important role in human health and species of bacteria have been associated with reproductive disease. Strain-level variation is also thought to be important, but the diversity, structure evolutionary history strains not as well characterized. We developed validated approach measure strain from metagenomic data based on SNPs within core genomes for six bacteria: ...

The unique crystalline protection of the surface states in topological crystalline insulators has led to a series of predictions of strain-generated phenomena, from the appearance of pseudo-magnetic fields and helical flat bands to the tunability of Dirac surface states by strain that may be used to construct 'straintronic' nanoswitches. However, the practical realization of this exotic phenome...

We have used high-speed video microscopy to measure in vivo length oscillations of the indirect flight muscles of the fruit fly Drosophila virilis during tethered flight. The changes in muscle strain were measured by tracking the deformation of the thoracic exoskeleton at the origin and insertion of both the dorsal longitudinal (DLM) and the dorsal ventral (DVM) muscles. The mean peak-to-peak s...

SUMMARY c The concept that creep response is the result of a transient approach to a minimum strain rate continuously modified by accumulating damage has been investigated using high precision creep data. It was considered that the accumulated creep strain might be some measure of internal damage and curves of log creep strain rate against creep strain are shown to exhibit linearity at higher s...
