Online social media offers an unprecedented laboratory to explore social interactions at scale. Yet it's hard to anticipate all the effects of a system with so many actors, and the systems we build are often re-appropriated by end users. To better understand how these systems are used, we employ mixed methods research to combine small-scale observations with large-scale data analysis. I'll prov...

Pumice fragments recovered from an archeological excavation on the Greek mainland have been correlated by means of index of refraction measurements with the Late Bronze Age volcanic eruption on the island of Thera (Santorini) in the Aegean Sea. Pottery from the strata containing the pumice dates from the 15th century B.C.

We introduced a novel method for the rapid synthesis of silver nanohexagonal thin columns from an aqueous mixture of sodium thiosulfate (Na2S2O3) and silver chloride (AgCl) simply added to a phosphor bronze substrate. The reaction is based on galvanic displacement and the products are potentially useful for plasmonic applications.

Consumption of fresh fruits and vegetables has been linked both anecdotally and clinically to the prevention or alleviation of chronic diseases and provides essential nourishment to mankind. The muscadine grape, a fruit indigenous to the southeastern U.S., contains several phenolic compounds that act as antioxidants and also other compounds, such as resveratrol, that can perform as a chemopreve...

In this article we examine a variety of quantitative models for describing archaeological networks, with particular emphasis on the maritime networks of the Aegean Middle Bronze Age. In particular, we discriminate between those gravitational networks that are most likely (maximum entropy) and most efficient (best cost/benefit outcomes).

A new partial differential model for monitoring and detecting copper corrosionproducts (mainly brochantite and cuprite) is proposed to provide predictive tools suitable for describing the evolution of damage induced on bronze specimens by sulfur dioxide (SO2) pollution. This model is characterized by the movement of a double free boundary. Numerical simulations show a nice agreement with experi...

The differential diagnosis of the bony lesions known as porotic hyperostosis found on a Bronze Age child's skull is discussed. Keith and Shattock gave an opinion in 1923 that the cause was rickets. A firm conclusion is not reached in this paper, but it is suggested that it was more likely to have been an iron-deficiency anaemia.

The paper introduces an overview on the researches we are currently carrying out on the integration of semantic aspects in Geographical Information Systems. Through an overview on the activities in the context of a project concerning the study of Bronze Age settlements in northern Italy, the paper shows how issues concerning semantics and GIS are currently faced to define an innovative and inte...

The second season of the archaeological survey of Qeshm Island was conducted during the winter of 2012, during which the team identified a total of 138 sites. The preliminary analysis of the ceramic assemblage from these sites suggests that 5 sites date to the 3rd millennium B.C.(Bronze Age) and represent the earliest in the directory. The remainder includes 3 Iron Age, 4 Achaemenid, 23 Parthia...
