A Prehistory of n-Categorical Physics [PDF]
This paper traces the growing role of categories and n-categories in physics, starting with groups and their role in relativity, and leading up to more sophisticated concepts which manifest themselves in Feynman diagrams, spin networks, string theory, loop quantum gravity, and topological quantum field theory. Our chronology ends around 2000, with just

Prehistory of Transit Searches [PDF]
Nowadays the more powerful method to detect extrasolar planets is the transit method. We review the planet transits which were anticipated, searched, and the first ones which were observed all through history. Indeed transits of planets in front of their star were first investigated and studied in the solar system.

BRS "Symmetry", prehistory and history [PDF]
Prehistory - Starting from 't Hooft's (1971) we have a short look at Taylor's and Slavnov's works (1971-72) and at the lectures given by Rouet and Stora in Lausanne-1973 which determine the transition from pre-history to history. History - We give a brief account of the main analyses and results of the BRS collaboration concerning the renormalized ...

Albert Einstein's 1916 Review Article on General Relativity [PDF]
The first comprehensive overview of the final version of the general theory of relativity was published by Einstein in 1916 after several expositions of preliminary versions and latest revisions of the theory in November 1915. A historical account of this review paper is given, of its prehistory, including a discussion of Einstein's collaboration with ...

John C.Baez reinterpreted 2-dimensional and 3-dimensional topological quantum field theories (abbreviated as 2-TQFT and 3-TQFT) in "A prehistory of n-categorical physics"[JC11]. Inspired by his idea, this paper utilizes cochains to prove some properties of 2-TQFT and 3-TQFT.

Elemental models of primate nursing and weaning revisited
Abstract Objectives Intra‐tooth patterns of trace elements barium (Ba) and strontium (Sr) have been used to infer human and nonhuman primate nursing histories, including australopithecine and Neanderthal juveniles. Here, we contrast the two elemental models in first molars (M1s) of four wild baboons and explore the assumptions that underlie each ...

Morphologies in‐between: The impact of the first steps on the human talus
Abstract Objective The development of bipedalism is a very complex activity that contributes to shaping the anatomy of the foot. The talus, which starts ossifying in utero, may account for the developing stages from the late gestational phase onwards.

Graphical Abstract. Abstract Famotidine (FAM) is an efficacious competitive drug, and a reversible inhibitor of H2‐histaminergic receptor action used to manage acid production in the stomach. Among the elderly population, this drug poses the risk of kidney failure and impaired mental health conditions. Additionally, FAM is an environmental contaminant.

Abstract The effects of the Younger Dryas (YD) fluctuation on Late Pleistocene hunter‐gatherers' settlement and subsistence systems in the southern Alps are poorly known. This is primarily due to the scarcity of archaeological sites dating from the YD, in contrast with the extensive evidence available from the lateglacial interstadial and the early ...
