متن کاملGood sequential probability forecasting is always possible
Building on the game-theoretic framework for probability, we show that it is possible, using randomization, to make sequential probability forecasts that will pass any given battery of statistical tests. This result, an easy consequence of von Neumann’s minimax theorem, simplifies and generalizes work by earlier authors.

WHEN HUMANS AND OTHER ANIMALS run and hop, they operate with muscle efficiencies nearly twice those observed during cycling (2, 4). This “free energy” is due to the storage and return of elastic energy in muscles and tendons during the stretch-shorten cycles of landing and takeoff (1). If spring-like tendons and muscles can save substantial energy, could artificial springs added to the legs fur...
متن کامل"Good Is Up” Is Not Always Better: A Memory Advantage for Words in Metaphor-Incompatible Locations
Four experiments examined whether memory for positive and negative words depended on word location and vertical hand movements. Cognitive processing is known to be facilitated when valenced stimuli are presented in locations that are congruent with the GOOD is UP conceptual metaphor, relative to when they are presented in incongruent locations. In both free recall and recognition tasks, we find...

In many of these protocols, including the popular BitTorrent, content is split into mostly fixed-size pieces, allowing a client to download data from many peers simultaneously. This makes piece size potentially critical for perf...
