New multivariable capabilities of the INCA program

The INteractive Controls Analysis (INCA) program was developed at NASA's Goddard Space Flight Center to provide a user friendly, efficient environment for the design and analysis of control systems, specifically spacecraft control systems. Since its inception, INCA has found extensive use in the design, development, and analysis of control systems for spacecraft, instruments, robotics, and pointing systems. The (INCA) program was initially developed as a comprehensive classical design analysis tool for small and large order control systems. The latest version of INCA, expected to be released in February of 1990, was expanded to include the capability to perform multivariable controls analysis and design

The Chanka: Archaeological Research in Andahuaylas (Apurimac), Peru

In AD 1438 a battle took place outside the city of Cuzco that changed the course of South American history. The Chanka, a powerful ethnic group from the Andahuaylas region, had begun an aggressive program of expansion. Conquering a host of smaller polities, their army had advanced well inside the territory of their traditional rival, the Inca. In a series of unusual maneuvers, the Inca defeated the invading Chanka forces and became the most powerful people in the Andes. Many scholars believe that the defeat of the Chanka represents a defining moment in the history of South America as the Inca then continued to expand and establish the largest empire of the Americas. Despite its critical position in South American history, until recently the Chanka heartland remained unexplored and the cultural processes that led to their rapid development and subsequent defeat by the Inca had not been investigated. From 2001 to 2004, Brian Bauer conducted an archaeological survey of the Andahuaylas region. This project represents an unparalleled opportunity to examine theoretical issues concerning the history and cultural development of late-prehistoric societies in this area of the Andes. The resulting book includes an archaeological analysis on the development of the Chanka and examines their ultimate defeat by the Inca. Series: Monographs 6

Structural basis for the homotypic fusion of chlamydial inclusions by the SNARE-like protein IncA.

Many intracellular bacteria, including Chlamydia, establish a parasitic membrane-bound organelle inside the host cell that is essential for the bacteria\u27s survival. Chlamydia trachomatis forms inclusions that are decorated with poorly characterized membrane proteins known as Incs. The prototypical Inc, called IncA, enhances Chlamydia pathogenicity by promoting the homotypic fusion of inclusions and shares structural and functional similarity to eukaryotic SNAREs. Here, we present the atomic structure of the cytoplasmic domain of IncA, which reveals a non-canonical four-helix bundle. Structure-based mutagenesis, molecular dynamics simulation, and functional cellular assays identify an intramolecular clamp that is essential for IncA-mediated homotypic membrane fusion during infection

On the human capital of Inca Indios before and after the Spanish conquest: Was there a "pre-colonial legacy"?

Not only the colonial period, but also the pre-colonial times might have influenced later development patterns. In this study we assess a potential pre-colonial legacy hypothesis for the case of the Andean region. In order to analyze the hypothesis, we study the human capital of Inca Indios, using age-heaping-based techniques to estimate basic numeracy skills. We find that Peruvian Inca Indios had only around half the numeracy level of the Spanish invaders. The hypothesis holds even after adjusting for a number of potential biases. Moreover, the finding has also crucial implications for the narrative of the military crisis of the Inca Empire. A number of explanations have been given as to why the Old American Empires were not able to defend their territory against the Spanish invaders in the early 16th century. We add an economic hypothesis to the debate and test it with new evidence: Were the human capital formation efforts of the Inca economy perhaps too limited, making it difficult to react appropriately to the Spanish challenge? --human capital,age-heaping,Inca empire,inequality,growth

What are GPs' preferences for financial and non-financial incentives in cancer screening? Evidence for breast, cervical, and colorectal cancers

We benefited for this research from grants provided by the French National Institute for Cancer (INCa) (INCA_7014). We would like to thank Dr Diane Skatun, Mary Kilonzo, and the three anonymous reviewers for their useful comments on the paper.Peer reviewedPostprin

Draft Genome Sequences of Pandrug-Resistant Serratia marcescens Clinical Isolates Harboring bla NDM-1

The draft genome sequences of two clonal, pandrug-resistant Serratia marcescens clinical isolates were determined. The resistance phenotype was plasmid driven, as 14 of 17 resistance genes were present on large IncFIB(K), IncHI2, and IncA/C2 plasmids indicating a large pool of transmissible antibiotic resistance genes

Garcilaso, reader of Gómara

Se aborda el uso dado por el Inca Garcilaso a la crónica indiana de Gómara (especialmente a su primera parte general, y en particular a la peruana), tanto en la obra publicada del Inca como en las apostillas agregadas por él a su ejemplar del libro de Gómara. Tras valorar la relación autor-lector en general, y la particular autoimagen de ‘comentador’ del Inca, se examinan las coincidencias entre ambas obras, y el estado de la cuestión en el tema de las fuentes del Inca Garcilaso. Se propone considerar de nuevo la utilidad de las críticas indigenistas de Gómara, tanto como su interés etnográfico por el Nuevo MundoAddresses use by Inca Garcilaso indiana Chronicle of Gómara (especially its first general part, and in particular the Peruvian), both in the published work of the Inca and Apostilles added it to their copy of the book de Gómara. After assessing the relationship break in general, and particular self-image of the Inca ‘commentator’, examines the overlap between both works, and the State of the art in the subject of the sources of the Inca Garcilaso. Intends to revisit the usefulness of indigenist Gómara criticisms, much as his ethnographic interest in the new world

The prediction and management of aquatic nitrogen pollution across Europe: an introduction to the Integrated Nitrogen in European Catchments project (INCA)

Excess nitrogen in soils, fresh water, estuarine and marine systems contributes to nutrient enrichment in key ecosystems throughout Europe, often leading to detrimental environmental impacts, such as soil acidification or the eutrophication of water bodies. The Integrated Nitrogenmodel for European Catchments (INCA) project aims to develop a generic version of the Integrated Nitrogen in Catchments (INCA) model to simulate the retention and transport of nitrogen within river systems, thereby providing a tool to aid the understanding of nitrogen dynamics and for river-basin management/policy-making. To facilitate the development of the model, 10 partners have tested the INCA model with data collected in study sites located in eight European countries as part of the INCA project. This paper summarises the key nitrogen issues within Europe, describes the main aims and methodology of the INCA project, and sets the project in the context of the current major research initiatives at a European level.</p> <p style='line-height: 20px;'><b>Keywords: </b>Europe, European Union, nitrogen, nitrate, ammonium, river basin management, modelling, water chemistry, acidification, eutrophication, Water Framework Directive, INCA
