Supportive communication has conventional tremendous attention for wireless networks. Most existing works on supportive infrastructure are focused on linklevel corporeal layer issues. Consequently, the impacts of supportive infrastructure on network-level upper layer issues, such as topology control, map-reading and network capacity, are largely disregarded. In this article, we propose a Capaci...

In 3 experiments, supportive audiences were associated with unexpected performance decrements (i.e., "choking" under pressure). On a difficult, skill-based task, participants were more likely to fail when observed by supportive audiences than when observed by nonsupportive audiences. When the criterion for success was easy, supportive audiences had no effect. With a difficult criterion, support...

Let A be any nonrecursive set. For each k 0, we show that there are functions (k + 1)-truth-table reducible to A that are not k-weak-truth-table reducible to A; and we show that there are functions (k + 1)-Turing reducible to A that are not k-Turing reducible to A. Intuitively, this means that k + 1 queries to a nonrecursive oracle are strictly more useful than k queries to the same oracle (for...

Scattering off the edge of a composite particle or finite-range interaction can precede that its center. An effective theory treatment with pointlike particles and contact interactions must find scattered experimental wave is slightly advanced, in violation causality (the fundamental underlying being causal). In practice, partial-wave other projections multivariate amplitudes exponentially grow...
