Higher-order Narrow-band Array Processing
This communication deals with narrow-band array processing using higher-order cumulants. A versatile tensor formalism is presented and adopted throughout to handle higher-order statistics of complex multivariates. We essentially focus on the use 4th-order cumulants for source localization in the spirit of the modern "subspace" techniques. We discuss "full cumulant tensor" solutions and their "d...
متن کاملCortical Sensory Responses Are Enhanced by the Higher-Order Thalamus.
In the mammalian brain, thalamic signals reach the cortex via two major routes: primary and higher-order thalamocortical pathways. While primary thalamocortical nuclei transmit sensory signals from the periphery, the function of higher-order thalamocortical projections remains enigmatic, in particular their role in sensory processing in the cortex. Here, by optogenetically controlling the thala...
متن کاملHigher order color mechanisms: A critical review
A large number of studies, using a wide variety of experimental techniques, have investigated the "higher-order" color mechanisms proposed by Krauskopf and colleagues in 1986. Results reviewed here come from studies of chromatic discrimination at threshold, habituation, classification images, spatial alignment and orientation effects, and noise masking. The bulk of the evidence has been taken t...
متن کاملRelationship Between Laterality and Handedness With the Higher Order Sensory Functions and Manual Dexterity of the Elderly
Objectives: The present study aimed to investigate the possible effects of laterality and handedness on higher-order sensory functions and manual dexterity of the elderly. Methods: In this non-experimental cross-sectional study, 58 elderly people aged 60-75 years (35 right-handed) were recruited through a convenience sampling method. Laterality of the selected subjects was examined using the E...
متن کاملVerification of Tree-Processing Programs via Higher-Order Model Checking
We propose a new method to verify that a higher-order, treeprocessing functional program conforms to an input/output specification. Our method reduces the verification problem to multiple verification problems for higher-order multi-tree transducers, which are then transformed into higher-order recursion schemes and model-checked. Unlike previous methods, our new method can deal with arbitrary ...
