A nonlinear small-strain elastic theory is constructed from a systematic expansion in Biot strains, truncated at quadratic order. The primary motivation the desire for clean separation between stretching and bending energies shells, which appears to arise only reduction of bulk energy this type. An approximation isotropic invariants, bypassing solution quartic equation or computation tensor squ...

Solid liquid crystals, formed by crosslinking polymeric nematics into elastomers are shown to display novel and complex elasticity. The internal (nematic) direction can experience a barrier to its rotation which couples to standard elasticity. We investigate this elasticity by considering imposed strains and demonstrate several new orientational phase transitions, caused by the interaction betw...

We examine how inputs for health production, in particular, medical care and health-enhancing time, are combined to improve health. The estimated elasticity of substitution from a constant elasticity of substitution production function is significantly less than one for the working-age population, rejecting the unit elasticity of substitution used in previous studies.

The purpose of this study was to compare large and small arterial elasticity in apparently healthy sedentary and recreationally active adult women, and to examine if age affects large and small arterial elasticity. This cross-sectional study consisted of 43 premenopausal women without overt cardiovascular disease (age = 43.4 ± 4.7 yrs; mean ± SD). The subjects were grouped into a sedentary grou...

BACKGROUND Emerging infectious diseases continue to pose serious threats to global public health. So far, however, few published study has addressed the need for manpower reallocation needed in hospitals when such a serious contagious outbreak occurs. AIM To quantify the demand elasticity of the major surgery types in order to guide future manpower reallocation during contagious outbreaks. ...
