Why is it that oxaloacetate is unable to permeate through the inner mitochondrial membrane?

In the Malate-aspartate shuttle, oxaloacetate is converted to malate before passing through the inner mitochondrial membrane. Oxaloacetate is regenerated from malate in the mitochondrial matrix.

How to define an anisotropic material with asymmetric elastic compliance/stiffness matrix in ANSYS APDL?

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...

Before we start the estimation process and its steps? Is there a quantitative regression model and a non-quantitative regression model? Follow@

The data are random samples from the population.

The independent variables are not perfectly nested.

The independent variables are precisely measured so that measurement error is small.

The expected value of the residuals is always zero.@

Good question, but I do not agree with the term quantitative regression? Because there is nothing but quantitative... and the estimation is done using ols@
