Analyses point to fluidity people’s earliest memories; furthermore, methodological variation leads individuals recalling memories from substantially earlier their lives. How early one’s “earliest” memor...

We argue that the random-matrix like energy spectra found in pseudointegrable billiards with pointlike scatterers are related to the quantum violation of scale invariance of classical analogue system. It is shown that the behavior of the running coupling constant explains the key characteristics of the level statistics of pseudointegrable billiards. 5.45.+b, 3.65.Db, 11.10.Gh Typeset using REVT...

Previous studies have suggested a variety of causes for the end-Permian extinction event including a bolide impact, flood basalt volcanism, methane clathrate dissociation, or some combination of catastrophic processes. One common feature of these hypotheses is the prediction of an enhanced earliest Triassic greenhouse. New high-resolution geochemical results from Graphite Peak, Antarctica suppo...
