We present a geometric framework for aligning white matter fiber tracts. By registering tracts between brains, one expects to see overlap of anatomical structures that often provide meaningful comparisons across subjects. However, the geometry is highly heterogeneous, and finding direct tract-correspondence multiple individuals remains challenging problem. novel deformation metric allows compar...

Abstract Parallel transport is a fundamental tool to perform statistics on Riemannian manifolds. Since closed formulae do not exist in general, practitioners often have resort numerical schemes. Ladder methods are popular class of algorithms that rely iterative constructions geodesic parallelograms. And yet, the literature lacks clear analysis their convergence performance. In this work, we giv...

The purpose of this paper is to compare the interaction between pricing and capacity decisions on simple serial and parallel transport networks. When individual links of the network are operated by different regional or national authorities, toll and capacity competition is likely to result. Moreover, the problem is potentially complicated by the presence of both local and transit demand on eac...
