Unfortunately, an error occurred in the equation on top of page 9. The correct sentence should be as follows:

The bending energy can be calculated as

$$ W_{{\text{b}}} = B/2{\int {{\left( {1/R^{2}_{1} + 1/R^{2}_{2} } \right)}\,} }{\text{d}}S $$

with B bending stiffness, R ₁ and R ₂ principal curvature radii, and S membrane surface (Canham 1970).
