A path-independent integral and the approximate analysis of strain
, 1968 : An integral is exhibited which has the same value for all paths surrounding a class of notches in two-dimensional deformation fields of linear or non-linear elastic materials.

Strain and Strain Rate Echocardiography
Methodist DeBakey Cardiovascular Journal, 2006 Myocardial function is eventually determined by the shortening and lengthening of myocardium, i.e., myocardial deformation or strain. The exact and direct measure of myocardial deformation has been dependent on the in vitro analysis of myocardial length.

Theoretical stress strain model for confined concrete
, 1988 A stress‐strain model is developed for concrete subjected to uniaxial compressive loading and confined by transverse reinforcement. The concrete section may contain any general type of confining steel: either spiral or circular hoops; or rectangular ...

Generic assignments, strain histories, and properties of pure cultures of cyanobacteria
, 1979 Summary: On the basis of a comparative study of 178 strains of cyanobacteria, representative of this group of prokaryotes, revised definitions of many genera are proposed.

Evaluation of 16S rRNA gene sequencing for species and strain-level microbiome analysis
Nature Communications, 2019 The 16S rRNA gene has been a mainstay of sequence-based bacterial analysis for decades. However, high-throughput sequencing of the full gene has only recently become a realistic prospect.

Sharp anisotropic estimates for the Boltzmann collision operator and its entropy production [PDF]
, 2011 This article provides sharp constructive upper and lower bound estimates for the non-linear Boltzmann collision operator with the full range of physical non cut-off collision kernels ($\gamma > -n$ and $s\in (0,1)$) in the trilinear $L^2(\R^n)$ energy $$.

High-extinction-ratio TE/TM selective Bragg grating filters on silicon-on-insulator [PDF]
, 2017 We report on the design and fabrication of TE and TM polarization selective Bragg grating filters in the form of sinusoidal perturbations on the waveguide sidewall and etched holes on the top of the waveguide, respectively.

Rheometer Strain and Strain-Rate Errors [PDF]
, 1990 We have found systematic errors which can affect measured rheological properties in the instrumentation of two commercial rheometers. Users of commercial instrumentation should establish the extent to which these and similar errors may exist in their systems.
