Let G = (V,E) be a graph and let f be a function f : E â†’ {0, 1, 2}. An edge x with f(x) = 0 is said to be undefended with respect to f if it is not incident to an edge with positive weight. Theâ€¦ (More)

Let G = (V,E) be a graph and f be a function f : V â†’ {0, 1, 2}. A vertex u with f(u) = 0 is said to be undefended with respect to f , if it is not adjacent to a vertex with positive weight. Theâ€¦ (More)

Near infrared (NIR) fluorescent molecules and nanosized structures can serve as potential optical probes for image-guided removal of small tumor nodules (â‰² 1 mm diameter). Although indocyanine greenâ€¦ (More)
