What Is the Complexity of Stieltjes Integration?
We study the complexity of approximating the Stieltjes integral R 1 0 f(x)dg(x) for functions f having r continuous derivatives and functions g whose sth derivative has bounded va...

Optimum bias for fast-switching free energy calculations
We derive the bias function that minimizes the statistical error of free energy differences calculated in work-biased fast-switching simulations. The optimum bias function is comp...

Isosurfaces Over Simplicial Partitions of Multiresolution Grids
We provide a simple method that extracts an isosurface that is manifold and intersection-free from a function over an arbitrary octree. Our method samples the function dual to min...

Surface Extraction from Binary Volumes with Higher-Order Smoothness
A number of 3D shape reconstruction algorithms, in particular 3D image segmentation methods, produce their results in the form of binary volumes, where a binary value indicates whe...
