1. Operadores-escada generalizados para sistemas quânticos
A superálgebra vem sendo aplicada na resolução de diversos problemas quânticos. Ela permite, por exemplo, obter soluções para potenciais exatamente solúveis e ampliar a construção de operadores de criação e destruição. Neste trabalho, o método de construção dos operadores-escada generalizados é revisado e usado para obter os autovalores de e

2. Uma avaliação sobre características espaço-temporais baseadas em invariantes de cor para reconhecimento de ações
Local spatiotemporal feature has been proved to be a powerful tool to represent latent patterns of moving objects in video scenes. In particular, recognition of human actions has been the principal focus for various growing applications, including video indexing, content-based video retrieval, video summarization, filtering of unwanted content, rating of mov

3. Quantization of continuous arm movements in humans with brain injury
Segmentation of apparently continuous movement has been reported for over a century by human movement researchers, but the existence of primitive submovements has never been proved. In 20 patients recovering from a single cerebral vascular accident (stroke), we identified the apparent submovements that composed a continuous arm motion in an unloaded task. Ki

4. Spatial spread of adaptation within the cone network of turtle retina.
1. The spatial characteristics of adaptation were studied in the red-sensitive cones of the snapping turtle retina using intracellular microelectrodes. Light responses elicited with slit-shaped test and adapting stimuli revealed that test response amplitudes and adaptation decline similarly with distance from the impaled cone. The spatial spread of adaptatio

5. Structural invariance of constitutively active and inactive mutants of Acanthamoeba myosin IC bound to F-actin in the rigor and ADP-bound states
The three single-headed monomeric myosin I isozymes of Acanthamoeba castellanii (AMIs)—AMIA, AMIB, and AMIC—are among the best-studied of all myosins. We have used AMIC to study structural correlates of myosin’s actin-activated ATPase. This activity is normally controlled by phosphorylation of Ser-329, but AMIC may be switched into constitutively activ
