Subsecond adaptation to directional motion can induce a rapid form of motion after-effect (rMAE). Unlike the characteristics of the classic motion after-effect (MAE), produced by adaptation of several seconds or minutes, the properties of the rMAE have been less well explored. In a series of experiments, we assessed the role of stationary and dynamic test patterns (counterphase flickering grati...

The temporal patterns of insertion of male palps, expansion of the hematodocha and duration of copulation are reported for 10 species of Schizocosa Chamberlin 1904, three species of Rabidosa Roewer 1955, one species of Gladicosa Brady 1986, one species of Hogna Simon 1885, two species of Isohogna Roewer 1960, one species of Trochosa C.L. Koch 1848, one species of Geolycosa Montgomery 1904, two ...

The present paper is a study of one impersonator and one of his voice imitations. The aim of the study was to investigate how he changes his own voice and speech behavior in order to get close to the target speaker’s. A comparison is made between three recordings of the same text material: the target speaker, the voice imitation and the impersonator’s own voice and dialect. The results presente...

A new nearest-neighbor method is described for estimating the Bayes risk of a multiclass pattern claSSification problem from sample data (e.g., a classified training set). Although it is assumed that the classification problem can be accurately described by sufficiently smooth class-conditional distributions, neither these distributions, nor the corresponding prior probabilities of the classes ...

The bias/variance tradeoff is fundamental to learning: increasing a model’s complexity can improve its fit on training data, but potentially worsens performance on future samples [1]. Remarkably, however, the human brain effortlessly handles a wide-range of complex pattern recognition tasks. On the basis of these conflicting observations, it has been argued that useful biases in the form of “ge...

OBJECTIVES To study changes in pattern and duration of breastfeeding associated with the introduction of solids and formula. STUDY DESIGN Descriptive longitudinal, prospective study. SETTING The participants were recruited from the maternity ward in the University Hospital in Uppsala, Sweden, between May 1989 and December 1992. A total of 15 189 infants were born during the period, 1 177 mo...

Introduction: Although hippocampus is the most famous brain area involved in temporal lobe epilepsy, hippocampal kindling (HK) develops very slowly. Hence, rapid kindling is usually preferred to the traditional kindling and it is widely used. In this article we aimed at finding the optimal stimulus pattern, which yields the fastest HK rate. Methods: Stimulus patterns with different duratio...

The current laboratory study is evaluating the effect of hydrofluoric acid etching duration on the surface characteristics of five silica-based glass ceramics. Changes in the pore pattern, crystal structure, roughness, and wettability were compared and evaluated. Seventy-five rectangularly shaped specimens were cut from each material (IPS e-max™, Dentsply Celtra™, Vita Suprinity™, Vita mark II™...
