We consider the problem of variational interpolation of subsets of Euclidean spaces by curves such that the L norm of the second derivative is minimized. It is well known that the resulting curves are cubic spline curves. We study geometric boundary conditions arising for various types of subsets such as subspaces, polyhedra, and submanifolds, and we indicate how solutions can be computed in th...
In this paper we consider the problem of reconstructing a subset A ⊂ Z n , up to translation, from the collection of its subsets of size k, given up to translation (its k-deck). Results of Alon, Caro, Krasikov, and Roditty [1] show that this is possible provided k > log 2 n. Mnukhin [10] showed that every subset of Z n of size k is reconstructible from its (k − 1)-deck, provided k ≥ 4. We show ...
A subset S of a poset (partially ordered set) is convex if and only if S contains every poset element which is between any two elements in S. Poset convex subsets arise in applications that involve precedence constraints, such as in project scheduling, production planning, and assembly line balancing. We give a strongly polynomial time algorithm which, given a poset and element weights (of arbi...
BACKGROUND Monocytes are critical in innate immunity and transplantation. Three monocyte subsets exist, CD14(++)CD16(-), CD14(++)CD16(+) and CD14(+)CD16(++) monocytes; cell counts of CD14(++)CD16(+) and CD14(+)CD16(++) monocytes are increased in pre-transplant chronic kidney disease. Interestingly, the effect of immunosuppressants on monocyte heterogeneity has not been well studied. METHODS T...
