SPRINGS (CLASSIFICATION, FUNCTION, CAPTURING)

Do muscles function as adaptable locomotor springs?

During normal animal movements, the forces produced by the locomotor muscles may be greater than, equal to or less than the forces acting on those muscles, the consequences of which significantly affect both the maximum force produced and the energy consumed by the muscles. Lengthening (eccentric) contractions result in the greatest muscle forces at the lowest relative energetic costs. Eccentri...

Modulation of Cardiac Function: Titin Springs into Action

Sympathetic stimulation has become a central tenet in our understanding of how cardiac contractility is dynamically altered to accommodate the changing demands of the organism. The mechanisms by which acute and chronic sympathetic stimulation of the heart modulates cardiac output remain incompletely understood, however. Beyond the increase in heart rate driven by sympathetic stimulation of the ...

Improving Chernoff criterion for classification by using the filled function

Linear discriminant analysis is a well-known matrix-based dimensionality reduction method. It is a supervised feature extraction method used in two-class classification problems. However, it is incapable of dealing with data in which classes have unequal covariance matrices. Taking this issue, the Chernoff distance is an appropriate criterion to measure distances between distributions. In the p...

Capturing the Cloud: UAP56 in Nuage Assembly and Function

The nuage is a hazy electron-dense structure unique to germ cells and is enriched in components of the piRNA pathway. Although the nuage is cytoplasmic, Zhang et al. now show that it is organized by an intranuclear protein, UAP56.
