The structure of the first invited debate in JMASM is to present a target article (Sawilowsky, 2003), provide an opportunity for a response (Roberts & Henson, 2003), and to follow with independent comments from noted scholars in the field (Knapp, 2003; Levin & Robinson, 2003). In this rejoinder, I provide a correction and a clarification in an effort to bring some closure to the debate. The int...

We present an algorithm that checks the duality of a pair of monotone Boolean expressions in disjunctive normal form in polynomial time plus O(log n/ log logn) nondeterministic guesses, where n is the size of the input, thus improving a previous result of Kavvadias and Stavropoulos [IPL, 85(1):1–6, 2003] and Eiter et al. [STOC 2003] which placed the problem in co-NP[log n], the subclass of co-N...

As part of the BIOSANT program (biologically-inspired smart nanotechnology), scientists at NASA-Langley have identified a “self-healing” plastic that spontaneously closes the hole left by the passage of a bullet. To understand and generalize the phenomenon in question, the mechanical properties responsible for this ability are being explored. Low-rate impression testing was chosen to characteri...
