The coordinate system has been proposed as a fundamental and cross-culturally used spatial representation, through which people code location and direction information in the environment. Here we provided direct evidence demonstrating that daily experience with the cardinal coordinate system (i.e., east, west, north, and south) contributed to the representation of cognitive maps. Behaviorally, ...
In this paper, we study the reconstruction of functions in spline subspaces from local averages. We present an average sampling theorem for shift invariant subspaces generated by cardinal B-splines and give the optimal upper bound for the support length of averaging functions. Our result generalizes an earlier result by Aldroubi and Gröchenig.
We show that for each positive integer k there is a sequence Fn : R → R of continuous functions which represents via point-wise limits arbitrary functions G : X → R defined on domains X ⊆ R of sizes not exceeding a standard cardinal characteristic of the continuum.
