Modeling the behavior of an underwater acoustic relative positioning system based on Complementary Set of Sequences
(Molecular Diversity Preservation International, 2011-12)
The great variability usually found in underwater media makes modeling a challenging task, but helpful for better understanding or predicting the performance of future deployed systems. In this work, an underwater acoustic ...
Field Guide on the orfovician of the Sierra Pintada, San Rafael Block, Mendoza
(Centro Argentino de Información Científica y Tecnológica. Instituto Superior de Correlación Geológica, 2002-12)
First day: Departure from San Juan City by bus, at 8 AM. Arrival at San Rafael City (about 370 km towards the South) in Mendoza Province at lunch time. During the trip by the plain road we can see the Eastern Precordillera ...
Early Paleozoic accretionary orogenies in NW Argentina: Growth of West Gondwana
(Elsevier Science, 2018-12)
Two Early Paleozoic orogenic cycles in the Gondwana margin of NW Argentina were driven by subduction, and interrupted by collision of continental ribbons of Laurentian affinity. Subduction started at the passive margin of ...
Real-time rescheduling of production systems using relational reinforcement learning
(QUALIS CAPES (UFSC), 2011-12)
Most scheduling methodologies developed until now have laid down good theoretical foundations, but there is still the need for real-time rescheduling methods that can work effectively in disruption management. In this ...
Measuring Time-of-Flight in an Ultrasonic LPS System Using Generalized Cross-Correlation
(Molecular Diversity Preservation International, 2011-10)
In this article, a time-of-flight detection technique in the frequency domain is described for an ultrasonic Local Positioning System (LPS) based on encoded beacons. Beacon transmissions have been synchronized and become ...
Analysis of HIV type 1 BF recombinant sequences from south america dates the origin of CRF12-BF to a recombination event in the 1970s
(Mary Ann Liebert, 2011-05)
HIV-1 epidemics in South America are believed to have originated in part from the subtype B epidemic initiated in the Caribbean/North America region. However, circulation of BF recombinants in similar proportions was ...
Historical records under the genetic evidence: “Chiriguano” tribe genesis as a test case
(Springer, 2018-10)
Historical records suggest that Chiriguano tribe is the result of a genetic admixture event. The process involved the arrival of Guaraní tribesmen descending from Amazonian region of Brazil along with groups of Arawak ...
First report of pre-Hispanic Fasciola hepatica from South America revealed by ancient DNA
(Cambridge University Press, 2019-12)
It is generally assumed that the digenean human liver fluke, Fasciola hepatica, gained entry to South America during the 15th century upon arrival of Europeans and their livestock. Nonetheless in Patagonia, Argentina, ...
Phylodynamics of Merkel-cell polyomavirus and human polyomavirus 6: A long-term history with humans
(Academic Press Inc Elsevier Science, 2018-09)
New human polyomaviruses have been described in the last years, including the Merkel-cell polyomavirus (MCPyV; Human polyomavirus 5) and the Human polyomavirus 6 (HPyV6). Although their infection is usually asymptomatic, ...
African matrilineages in American Creole cattle: Evidence of two independent continental sources
(Wiley Blackwell Publishing, Inc, 2006-08)
In order to clarify the historical origin and phylogeographic affinities of Creole cattle matrilineages throughout the American continent, we analysed published D-loop mtDNA sequences (n = 454) from Creole, Iberian and ...
