Radiocarbon chronology of Manot Cave, Israel and Upper Paleolithic dispersals
Science Advances, 2017 Manot Cave radiocarbon dates establish Levantine chronology, which is critical for understanding Upper Paleolithic dispersals. The timing of archeological industries in the Levant is central for understanding the spread of modern humans with Upper ...

Chronology Protection and Quantized Fields: Complex Automorphic Scalar Field in Misner Space [PDF]
Class.Quant.Grav.14:523-534,1997, 1995 The renormalized stress-energy tensor $\langle T_{\mu\nu}\rangle$ of the quantized complex massless scalar field which obeys the automorphic condition in Misner space is obtained. It is shown that there exists the special value of the automorphic parameter for which $\langle T_{\mu\nu}\rangle$ is regular on the chronology horizon and, so, can not act ...

Glacial varves at the distal slope of Pandivere-Neva ice-recessional formations in western Estonia [PDF]
Bulletin of the Geological Society of Finland, 2012 The distribution and varve thickness data of Late Weichselian varved clay were analyzed to describe the proglacial sedimentary environment, ice recession and water-level changes in the Baltic Ice Lake at the distal position of Pandivere–Neva (13.5–13.1 ...

Quantum Complex Scalar Field in the Two-Dimensional Spacetime with Closed Timelike Curves and a Time-Machine Problem [PDF]
Class.Quant.Grav.12:1685-1698,1995, 1994 It is considered the quantum complex scalar field which obeys the authomorphic condition in the two-dimensional spacetime with closed timelike curves and the chronology horizon. The renormalized stress-energy tensor is obtained. It is shown that the value of the stress-energy tensor is regular at the chronology horizon for specific authomorphic ...

SSRN Electronic Journal, 2007 <p>We process information in a large number of Canadian wage contracts, signed over a period of several decades, to generate the long-run history of the real wage for each bargaining pair. We term these hitherto unexamined histories ‘chronologies’. We are able to generate 1574 continuous real wage chronologies and we examine the evolution of the

Chronology Protection in AdS/CFT [PDF]
Fortsch.Phys. 54 (2006) 317-322, 2006 We review the issue of chronology protection and show how string theory can solve it in the half BPS sector of AdS/CFT. According to the LLM prescription, half BPS excitations of AdS_5 x S^5 geometries in type IIB string theory can be mapped into free fermion configurations.
