From neural and social cooperation to the global emergence of cognition

Description: This article elaborates on a discussion of the emergence of intelligence via criticality as a consequence of locality breakdown, by using criticality for the foundation of a novel generation of game theory making the local interaction between players yield long-range effects.

Giant cross-magnetic-field steps due to binary collisions between pair particles

Description: Article explores giant cross-magnetic-field steps which occur as a result of positron-electron collisions. Within a constant magnetic field (e.g., 1 T), a collision between a positron and an electron can result in a correlated drift across the magnetic field for a continuous range of impact parameters. Within this range, drift distances orders of magnitude larger than that associated with like-charge collisions were observed by computer simulation.

Ion Beam Analysis of Microcrystalline Quartz Artifacts from the Reed Mound Site, Delaware County, Oklahoma

Description: This paper from the 23rd Conference on Application of Accelerators in Research and Industry conference proceedings evaluates the potential of particle induced X-ray emission spectrometry as a tool for future Ozarks chert provenance studies based on its ability to facilitate discrimination of Ozarks chert materials from different geological formations and identification of discrete groups of artifacts from the same geological formation.
