Localized surface instabilities have been used to explain the transformation to a butterfly shape of a cubic precipitate submitted to epitaxial stress. An energy variation calculation shows that each of the pre
The basic shape function for the coordinate: (1.7)xξ=∑i=1nenNiEξxi=NiEξxi. Here; NiEξ, is the shape function at node i; ξ, is the element local coordinate; and xi, is the nodal coordinate at node i; nen, is the number of nodes per element, respectively. The interpolation fo...
function v = watervol(h) % watervol calculates the volume of the water in the water tower. % The input is the water level in meters. % The output is the water volume in cubic meters. if h<= 19 v = pi*12.5A 2*h; else rh=12.5 + 10.5*(h-19)/14; ...
We first implement self-limiting assembly in a two-dimensional plane in solution (Fig. 1) with wedge-shaped building blocks (‘V bricks’), the opening angles of which encode the number of subunits in ring oligomers (Fig. 1a, b). V-brick oligomerization is mediated by two asymmetric, inte...

xy+ 2y2+z2is a ternary quadratic form. If the variables can be divided into sets such that each term of the form is linearly dependent on the variables of each set, the form is said to be multilinear. An example of a multilinear form is a determinant regarded as a function of its ...

function padAngle() { return d && d.padAngle; }The pad angle is converted to a fixed linear distance separating adjacent arcs, defined as padRadius * padAngle. This distance is subtracted equally from the start and end of the arc. If the arc forms a complete circle or annulus, as ...
This paper presents aC1-interpolation which preserves convexity to scattered convex data. The interpolant is local and explicitly described. The interpolating function si(x) is C2on each interval(@#@xi,xi+1@#@).Error will beO(h2) when the function to be interpolated is C3. ...
Our dimensionless, unbiased and position-independent shape compactness prior is based on a measure that is well accepted in the context of shape metrics [16], the ratio of length-squared to area, which we can write in discrete form (i.e., as a function of our segmentation variable): Ec(...
