El Pilar is a major Maya archeological site with components located on either side of the Belize-Guatemala frontier. This site presents an opportunity to explore the concept of "multiple use" of the natural resources of the greater Maya Forest in ways that have not yet been attempted. Success in such an endeavor would provide benefits to Mexico, Guatemala and Belize that envelop, countries with...

We study the problem of fitting circles to scattered data. Unlike many other studies, we assume that the noise is (strongly) correlated; we adopt a particular model where correlations decay exponentially with the distance between data points. Our main results are formulas for the maximum likelihood estimates and their covariance matrix. Our study is motivated by (and applied to) arcs collected ...

The sacred 260-day Mesoamerican calendar probably originated near a latitude of 15 degrees N, where there is a 260-day interval between transits of the zenithal sun. Archeological and faunal evidence favors an origin in the Pacific lowlands rather than in the highlands near Copán, Honduras, although Copán, which is located at the 15th parallel of latitude, later became the principal Mayan astro...

Archeological sites have heterogeneous information ranging from different artifacts, image data, geo-spatial information, chronological data, and other relevant metadata. ETANA-DL, an archaeology digital library, provides various services by integrating the heterogeneous data available in different collections. This demonstration presents an initial prototype for searching DL objects based on t...

Many crucial components of signal transduction, developmental, and metabolic pathways have functionally redundant copies. Further, these redundancies show surprising evolutionary stability over prolonged time scales. We propose that redundancies are not just archeological leftovers of ancient gene duplications, but rather that synergy arising from feedback between redundant copies may serve as ...

In this paper we present the development of a methodology for creating multilingual thesauri of period names based on CIDOC CRM, archeological theory and results from Computer Science and Knowledge Representation. Periods are defined by identity criteria (coming from the archaeological evidence) rather than by time and place. A formal model in the form of XML DTD has been developed as a proposa...

A specimen of the murid rodent Nesokia indica has been recovered from a late Paleolithic archeological site in the Sudan. This is a range 1200 km south of the site of any known occurrences, and it indicates a different environment near the Nile River than that which exists at the present time. The late Paleolithic water table is inferred to have been more stable, allowing for permanent moist soil.

WHEN I was asked on behalf of the council of the British Association to occupy the responsible post of president at the meeting in this great city-the third that has taken place here-I was certainly taken by surprise; the more so as my own subject of research seemed somewhat removed from what may be described as the central interests of your body. The turn of archeology, however, I was told, ha...

From the 17th to 19th century, a score of military events, campaigns and battles took place in Czech lands, leaving numerous traces distinctly changing appearance cultural landscape some regions. The results long-term aerial-archeological surveys lands have demonstrated that this detection method is advantageous identifying buried sites built past context conflicts. Experience hitherto has made...

This article presents cases of treponematosis in at least five individuals from different archeological sites southern North Eastern Argentina and discusses how these were linked to the ways life pre-Hispanic groups that inhabited this region for 2000 years. We carried out reanalysis reinterpretation some pathological cases, including a comparison between our observations previous diagnoses mad...
