When two kinases are better than one
When two kinases are better than one V idal-Eychenié et al. describe how two protein kinases team up to respond to DNA damage at stalled replication forks. DNA-dependent protein kinase catalytic subunit (DNA-PKcs) promotes the repair of DNA double-strand breaks (DSBs) by nonhomologous end joining (NHEJ). The ATR kinase, on the other hand, initiates cell cycle arrest and DNA repair after recogni...
متن کاملWhen Three Heads Are Better Than Two
The present study investigated the effects of both group size and heterogeneity in relevant math skill on collaborative problem solving. Overall, triads demonstrated better reasoning and more effective cryptarithmetic problem solving than dyads and singletons. Importantly, triads outperformed the best individuals in a nominal groups analysis. Triads were also better able than dyads to take adva...
متن کاملWhen Are K + 1 Queries Better than K?
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...
متن کاملWhen FGPAs are better at floating-point than microprocessors
It has been shown that FPGAs could outperform high-end microprocessors on floating-point computations thanks to massive parallelism. However, most previous studies reimplement in the FPGA the operators present in a processor. This is a safe and relatively straightforward approach, but it doesn’t exploit the greater flexibility of the FPGA. This article is a survey of the many ways in which the ...
متن کاملWhen two heads are better than one expert
In a line of research on expertise and creative problem solving (Wiley, 1998; Wiley, 1999), an instance in which two heads do seem better than one has been found. In a study using a Remote Associates Task, when high knowledge participants were paired with a novice, solution rates actually increased beyond what would be expected from either type of individual working independently. The discovery...
