Dynamics of staying put
Pygo2 opens chromatin and cycles cells B y spreading an active chromatin state, Pygo2 prompts the proliferation of mammary gland progenitor cells, report Gu et al. The fl y version of Pygo2, Pygopus, is essential for Wg signaling. But the relationship between mammalian Wg (Wnt) and Pygo2 is less clear. Pygo2 is necessary for the development of a number of tissues, but in the two best studied—ey...
متن کاملIs Working More Costly than Waiting in Monkeys?
We studied how value for instrumental action is discounted by predicted effort and delay. The monkeys were trained to perform instrumental trials that required a bar release when a visual target changed from red-to-green. There were two trial conditions. In delay trials, after the monkeys performed one instrumental trial correctly a reward was delivered 0-7 seconds later. In work trials, the mo...

The present study was undertaken to evaluate the prevalence of long-term staying in an emergency ward. Methods: In the present 2-month cross-sectional study, patients referring to the emergency ward of Imam Hos...
متن کاملStaying Alive Longer: Autonomous Robot Recharging Put to the Test
Autonomous mobile robots are being developed for numerous applications where long-term capabilities would be beneficial. However, most mobile robots have onboard power supplies in the form of batteries that last for a finite amount of time, in which case the robot becomes reliant on human intervention for extended usage. To achieve true long-term autonomy, the robot must be selfsustaining in it...
متن کاملExtremely costly intensifiers are stronger than quite costly ones
We show how the wide range in strengths of intensifying degree adverbs (e.g. very and extremely) could be explained by pragmatic inference based on differing cost, rather than differing semantics. This predicts a linear relationship between the meaning of intensifiers and their length and log-frequency. We test this prediction in two studies, using two different dependent measures, finding that...
