They are distributed from Southern of Central America to northern of South America. Saguinus bicolor have very limited geographic distribuition, affected by demographic expansion of the city Manaus. In contrast, Saguinus midas have largest geographic distribuition among the Saguinus. They share the same characteristics general and overlap the north of Manaus. Cytogenetics studies with Saguinus described a karyotypic macrostructure conserved, with 2n=46 and patterns of similar bands. However, mapping studies of repetitive sequence are incipient. Repetitive sequence in tandem: telomere and rDNA; and repetitive sequence dispersed include the transposable elements were searched in the work. Analysis were made on S. midas and two populations of S. bicolor. The classical cytogenetics confirmed macrostructure of 2n=46, but differed in morphology of chromosomes, classified into: 8 metacentrics; 10 submetacentrics; 10 subtelocentrics and 6 acrocentrics. The patterns bands were similar, but showed variations among individuals of the same species. The G-bands patterns suggest the fourth pair as cytogenetic markers that show differences among two species and identify natural hybrids in contact zone. The NOR’s were detected in pairs 17 and 18, agreeing with the localization of sequences of rDNA 18S in region pericentromeric of long arms of chromosomes 17, 18 and 19, located in heterochomatic region. LINE–1 was found in regions: euchromatics – having an impact on the organization and function of genome, and; heterochromatics - particularly in centromeric heterochromatin. Accumulation in sex chromosomes are associated with inactivation of one chromosome X in females to promote the gene silencing and ensure gene dosage of sex pair when compared with male. It is possible to observe his presence in regions of negatives G-bands (light bands) implying that deposition in genome of S. bicolor and S. midas is recent in evolutionary time. Differences of sinalization of LINE-1 among populations of S. bicolor were detected, possibly due to isolation the two populations. / Saguinus é o maior e mais complexo gênero da subfamília Callitrichinae, com 23 espécies. Eles estão distribuídos do sul da América Central ao norte da América do Sul. Saguinus bicolor possui uma distribuição geográfica muito limitada, afetada pela expansão demográfica da cidade de Manaus. Ao contrário, Saguinus midas possui a maior distribuição geográfica dentre os Saguinus. São próximas filogeneticamente, compartilham das mesmas características gerais e se sobrepõem ao norte de Manaus. Estudos citogenéticos dos Saguinus descrevem uma macroestrutura cariotípica conservada, com 2n=46 e padrões de bandas similares. Porém, estudos com mapeamento de sequências repetitivas são incipientes. Sequências repetidas em tandem: telômericas e DNAr, e; sequências repetitivas dispersas que englobam os elementos transponíveis são pesquisadas neste trabalho. Análises citogenéticas foram feitas em S. midas e duas populações de S. bicolor. A citogenética clássica confirmou a macroestrutura das duas espécies em 2n=46, porém diferiu na morfologia dos cromossomos quando comparadas com estudos anteriores, sendo aqui, classificados em: 8 M; 10 SM; 20 ST e 6 A. O padrão de banda G apresentou variações entre as espécies, sugerindo o quarto par como marcador citogenético que diferenciaria as duas espécies e identificaria híbridos naturais de 1a geração, em zona de contato. As RON’s foram detectadas nos pares 17 e 18, sendo confirmadas pela localização da sequência de DNAr 18S na região pericentromérica dos braços longos nos cromossomos 17, 18 e 19, localizada em regiões próximas as heterocromatinas. A sequência LINE-1 foi encontrada nas regiões: eucromáticas – podendo influenciar na organização e função do genoma, e; heterocromáticas - particularmente na heterocromatina centromérica. O acúmulo de LINE-1 nos cromossomos sexuais está relacionado com a inativação de um dos cromossomos X nas fêmeas garantindo a dosagem gênica do par sexual quando comparado com os machos. A presença de LINE- 1 nas regiões de bandas G negativas (bandas claras) indica que sua deposição no genoma de S. bicolor e S. midas é recente no tempo evolutivo. Diferenças de sinalização do LINE-1 entre populações de S. bicolor foram detectadas, possivelmente devido ao isolamento das duas populações.

Generating Members of a Software Product Line Using Combinatory Logic

Hoxha, Armend 04 May 2015 (has links)
A Product Line Family contains similar applications that differ only in the sets of sup-ported features from the family. To properly engineer these product lines, programmers design a common code base used by all members of the product line. The structure of this common code base is often an Object-Oriented (OO) framework, designed to contain the detailed domain-specific knowledge needed to implement these applications. However, these frameworks are often quite complex and implement detailed dynamic behavior with complex coordination among their classes. Extending an OO framework to realize a single product line instance is a unique exercise in OO programming. The ultimate goal is to develop a consistent approach, for managing all instances, which relies on configuration rather than programming. In this thesis, we show the novel application of Combinatory Logic to automatically syn-thesize correct product line members using higher-level code fragments specified by means of combinators. Using the same starting point of an OO framework, we show how to design a repository of combinators using FeatureIDE, an extensible framework for Feature-Oriented Software Development. We demonstrate a proof of concept using two different Java-based frameworks: a card solitaire framework and a multi-objective optimization algorithms framework. These case studies rely on LaunchPad, an Eclipse plugin developed at WPI that extends FeatureIDE. The broader impact of this work is that it enables framework designers to formally en-code the complex functional structure of an OO framework. Once this task is accomplished, then, generating product line instances becomes primarily a configuration process, which enables correct code to be generated by construction based on the combinatory logic.
