Geometric frustration results from an incompatibility between minimum energy arrangements and the geometry of a system, and gives rise to interesting and novel phenomena. Here, we report geometric frustration in a native biological macromolecular sys

An algorithm is described for exact enumeration of the ground states of the antiferromagnetic Ising model on a triangular lattice for particular finite domains and boundary conditions. A direct constructive approach is used that allows easy incorpora

Image Reconstruction from Incomplete Data IV.
Myosin filaments are important components of striated muscle and pack in a semi-ordered, two-dimensional array. The array can be imaged by electron microscopy of thin cross-sections which indicates, for many species, that the filaments adopt two orie

An image whose region of support is smaller than its bounding rectangle can, in principle, be reconstructed from a subset of the Nyquist samples. However, determining such a sampling set that gives a stable reconstruction is a difficult and computati

Recovery of magnetic resonance images from irregular sampling sets is investigated from the point of view of moment discretization of the Fredholm equation of the first kind. The limited spatial extent of the object is known a priori and the sampling

A method is presented for partial recovery of limited extent images from spectra sampled regularly but below the Nyquist density. The non-iterative method requires only relatively small systems of linear equations to be solved. With particular releva

In imaging situations where observations are made in spatial-frequency space, it is often desirable to lower the number of observations to fewer than that imposed by the Nyquist criterion. It is shown that patterns of regular spectral undersampling l
