Objectives: To compare the physical performance and responses obtained in the six-minute walking test (6MWT) and the six-minute step test (6MST) between asthmatic and healthy adolescents; and to investigate the relationship between the responses obtained in the tests and the body mass index (BMI), physical activity level and spirometric variables. Methods: Nineteen asthmatic adolescents (AG) an...

Statistic language models obtained from a large number of training samples play an important role in speech recognition. In order to obtain higher recognition performance, we should introduce long distance correlations between words. However, traditional statistic language models such as word n-grams and ergodic HMMs are insufficient for expressing long distance correlations between words. In t...

When dealing with graphical Gaussian models for gene regulatory networks, the major problem is to compute the matrix of partial correlations. Based on the close connection between partial correlations and least squares regression, we suggest estimation of high-dimensional gene networks in terms of partial least squares (PLS) regression and the adaptive Lasso, respectively. In a simulation study...

Hypothesis: Natural selection shapes correlations between morphology and performance through variation in ecology (habitat use). Organism: Anolis sagrei lizards (the brown anole). Field site: A small offshore island near Great Exuma, Bahamas. Methods: I measured morphology, physiological performance [e.g. sprint speed, sprint sensitivity (the change in speed on broad versus narrow surfaces), ru...

Over repeat presentations of the same stimulus, sensory neurons show variable responses. This "noise" is typically correlated between pairs of cells, and a question with rich history in neuroscience is how these noise correlations impact the population's ability to encode the stimulus. Here, we consider a very general setting for population coding, investigating how information varies as a func...

How visual object categories are represented in the brain is one of the key questions in neuroscience. Studies on low-level visual features have shown that relative timings or phases of neural activity between multiple brain locations encode information. However, whether such temporal patterns of neural activity are used in the representation of visual objects is unknown. Here, we examined whet...
