If the purpose of adaptation is to fit sensory systems to different environments, it may implement an optimization of the system. What the optimum is depends on the statistics of these environments. Therefore, the system ...

We present a series of experiments exploring the effect of the stimulus spatial configuration on speed discrimination and two different types of segmentation, for random dot patterns. In the first experiment, we find that ...

It has been shown that knowing the size of an approaching object affects our perception of time to collision (TTC) in a manner similar to the way it affects perception of the physical speed of objects moving in the ...

Sleep supports the consolidation of memory, and it has been proposed that this enhancing effect of sleep pertains in particular to memories which are encoded under control of prefrontal–hippocampal circuitry into ...

In this paper, the fundamentals of a prospective Internet that aims to collect electric charge of virions at streets is presented. The purpose of this paper is twofold: (i) In one hand to demonstrate the capability of ...

OBJECTIVE: The aim of this study was to build a prediction model to discriminate precociously hantavirus infection from leptospirosis, identifying the conditions and risk factors associated with these diseases. METHODS: A ...

Multivariate techniques allow to understand the structural dependence contained in the variables, as well as to characterize groups of seed lots according to specific standards. Thus, this study analyzes the efficiency of ...

The discrimination of different land uses based on satellite data is a widely used procedure, mainly because of processing speed and low cost of realization, depending on the sensor used. The process becomes complex when ...

PURPOSE: to propose a version of the Portuguese Sentences Lists test with slowed speech speed; to verify the naturalness, clarity and applicability of the new material; to evaluate the change in the recognition performance ...
