We analyze a class of estimators based on convex relaxation for solving high-dimensional matrix decomposition problems. The observations are noisy realizations of a linear transformation X of the sum of an (approximately) low rank matrix with a second matrix endowed with a complementary form of low-dimensional structure; this set-up includes many statistical models of interest, including factor...

Species composition can vary among different types of habitat and is defined by the dependency species on resources. The positive relationship between forest functions increasing interest to researchers.

To the Editor: Purkinje cells constitute the sole output of the cerebellar cortex. They play pivotal roles in maintaining balance and regulating movement by modulating the firing response of the deep cerebellar nuclei. Electrophysiological dysfunction of Purkinje cells brings about cerebellar ataxia. Accordingly, rescue of Purkinje cells could have important therapeutic implications. In spite o...
