We reveal the significance of plasmonic nanoparticle’s (NP) shape and its surface morphology en route to an efficient self-assembled plasmonic nanoparticle cluster. A simplified model is simulated in the form of free-space dimer and trimer nanostructures (NPs in the shape of a sphere, cube, and disk). A ~200% to ~125% rise in near-field strength (gap mode enhancement) is observed for spherical NPs in comparison with cubical NPs (from 2 nm to 8 nm gap sizes). Full-width three-quarter maximum reveals better broad-spectral optical performance in a range of ~100 nm (dimer) and ~170 nm (trimer) from spherical NPs as compared to a cube (~60 nm for dimer and trimer). These excellent properties for sphere-based nanostructures are merited from its dipole mode characteristics.

Este trabalho tem como objetivo revisar a forma como é observada a estrutura industrial brasileira e avaliar se esta pode ser qualificada como de ‘regressiva’. Para isto será utilizado: (i) uma classificação industrial específica construída a partir de um conjunto de indicadores relativos aos resultados de inovação; (ii) a evolução do crescimento das exportações mundiais para cada cluster contemplado; (iii) os efeitos de encadeamento (up e downstream) de cada cluster. A partir desta caracterização, o trabalho revisa a evolução da produção industrial, a estrutura de exportações e o desempenho industrial do Brasil entre 1996 e 2011. O artigo conclui que não é possível qualificar a estrutura produtiva brasileira como regressiva por diversas razões. Primeiro, porque uma parte significativa de sua especialização em industrias tradicionais que exploram recursos naturais tem representativos efeitos encadeamento e um nível de conteúdo tecnológico médio-alto (petróleo).  Segundo, porque não ha diferenças significativas na agregação de valor entre as atividades com alto e baixo grau de inovatividade, ou seja, entre atividades onde o Brasil se especializa e não se especializa. Terceiro, porque o crescimento da produtividade real está positiva e significativamente relacionado com a evolução da estrutura industrial em termos de valor agregado, ou seja, a diversificação industrial contribuiu positivamente ao crescimento da produtividade industrial.

ABSTRACT Twelve mutations affecting nuclear migration, a major developmental phase in Schizophyllum commune, display a complex pattern of complementation and recombination. They are expressed only when a genetic factor controlling this phase of development, the B incompatibility factor, is operative. All twelve mutations are linked to the B factor, nine in a cluster and three in distinct loci outside the cluster. A linear map cannot be constructed from the frequency of recombination. Complementation maps are not linear. There is little correlation between the complementation groups and the groups based on recombination. Many pairs of mutations that do not complement recombine with frequencies of 1.1% to 26.9%. The genes represented by the twelve mutations are located in a linked group of about 18 known genes involved in the specific phase of development controlled by the B factor.
