The sleeping neocortex shows nested oscillatory activity in different frequency ranges, characterized by fluctuations between "up-states" and "down-states." High-density neuronal ensemble recordings in rats now reveal the interaction between synchronized activity in the hippocampus and neocortex: Electroencephalographic sharp waves in the hippocampus were more probable during down-states than d...

OBJECTIVE Evaluate the efficacy of ramelteon, an MT/1MT2-receptor agonist, for the treatment of transient insomnia in healthy adults. DESIGN Randomized, double-blind, placebo-controlled design using a model of transient insomnia related to sleeping in a novel environment. SETTING Fourteen sleep research centers. PARTICIPANTS Healthy adults (N=375; 228 women), aged 35 to 60 years, who had ...

To understand the postnatal development of the cerebral cortex we must know how changes in one cortical area depend on inputs from other cortical areas. Do cortical areas serving early stages of processing (primary sensory receiving areas) mature first, passing relatively stable outputs about sensorimotor relationships to cortical areas involved in higher stages of processing that are still dev...

I have, in a series of publications (Wilber, 1977; 1980; 1981b; 1983), attempted to develop an overall or spectrum model of psychology, one that is developmental, structural, hierarchical, and systems-oriented, and that draws equally on Eastern and Western schools. Vis avis psychopathology the conclusion I reached was that the spectrum of consciousness is also a spectrum of (possible) pathology...

In this paper, a complete review of published researches about hierarchical facility location and hub network problems is presented. Hierarchical network is a system where facilities with different service levels interact in a top-down way or vice versa. In Hierarchical systems, service levels are composed of different facilities. Published papers from (1970) to (2015) have been studied and a c...

A hierarchical three-stage syntactic recognition algorithm using context-free grammars is described for automatic identification of skeletal maturity from X-rays of hand and wrist. The primitives considered are dot, straight line and arcs of three different curvatures (including both senses) in order to describe and interpret the structural development of epiphysis and metaphysis with growth of...

This study presents data on some phasic EEG phenomena regulary recorded during sleep - wakefulness cycle and heterogeneity of EEG sleep stages forming consecutive human sleep macrocycles. These short-term EEG changes quite often tend to periodization, especially during initial sleep-stages and transitive states (sleep microcycles). An attempt was made to reveal EEG microstructures in sleep - wa...

this survey is aimed to compare the hierarchical structure of subject directories, including yahoo, the open directory and looksmart with dewey decimal classification (ddc) in 10 selective subjects. five questions are raised to compare the broadness and the depth of the hierarchical structures in the subject directories and ddc and to study the effectiveness of the usage of ddc in the organizat...

Differentiable architecture search (DAS) has made great progress in searching for high-performance architectures with reduced computational cost. However, DAS-based methods mainly focus on a repeatable cell structure, which is then stacked sequentially multiple stages to form the networks. This configuration significantly reduces space, and ignores importance of connections between cells. To ov...
