Vocalizations of blue whales were recorded with a cabled hydrophone array at Pioneer Seamount, 50 miles off the California coast. Most calls occurred in repeated sequences of two-call pairs (A, then B). The B call is a frequency-modulated tone highly repeatable in form and pitch. A model of this sound is described which permits detecting very small frequency shifts. B calls are found to be alig...

The present study tested Japanese 4.5- and 10-month old infants' ability to discriminate three German vowel pairs, none of which are contrastive in Japanese, using a visual habituation-dishabituation paradigm. Japanese adults' discrimination of the same pairs was also tested. The results revealed that Japanese 4.5-month old infants discriminated the German /bu:k/-/by:k/ contrast, but they showe...

BACKGROUND AND PURPOSE The aim of this study was to identify the mechanism underlying the auditory discriminatory process reflected in mismatch negativity (MMN), using time-frequency analysis of single-trial event-related potentials (ERPs). METHODS Two auditory tones of different probabilities (oddball paradigm) and the same probability (control paradigm) were used. The average dynamic change...

AND CONCRETE SCHIZOPHRENICS 331 formulated a mediating-response theory of human discrimination learning. Mediatingresponse theory postulates that, in the process of discrimination learning, an implicit mediating S-R association is forced by which Ss learn to respond to a particular stimulus dimension. Since, in an R shift, the relevant dimension does not change, an R shift should be learned fas...

Failure to setup a large-scale hydrological model correctly may not allow proper calibration and uncertainty analyses, leading to inaccurate model prediction. To build a model with accurate accounting of hydrological processes, a data discrimination procedure was applied in this study. The framework uses a hydrological model of Alberta built with the Soil andWater Assessment Tool (SWAT) program...

The present study examines the consequences of perceived interpersonal discrimination on stress, health, and performance in a sample of 210 science, technology, engineering, and mathematics (STEM) academicians. Using a path model, we test the relation that perceived interpersonal discrimination has on stress and the relation of stress to physical health maladies and on current and future perfor...

Although studies show that adolescents with same-sex parents experience homophobic discrimination, little is known about associations between stigmatization and substance use in this population. The 17-year-old offspring of lesbian parents from the largest, longest-running, longitudinal study of same-sex parented families were surveyed about substance use, experiences of homophobic stigmatizati...

The option-pricing problem is always an important part in modern finance. Assuming that the stock diffusion is a constant, some literature has introduced many stock models and given corresponding option pricing formulas within the framework of the uncertainty theory. In this paper, we propose a new stock model with uncertain stock diffusion for uncertain markets. Some option pricing formulas on...

We find recursive formulae for the number of perfect matchings in a graph G by splitting G into subgraphs H and Q. We use these formulas to count perfect matching of P hypercube Qn. We also apply our formulas to prove that the number of perfect matching in an edge-transitive graph is , where denotes the number of perfect matchings in G, is the graph constructed from by deleting edges with an en...

conclusions stigma and discrimination play an important role in patients' lives and hinder them from accessing the treatment. the patients' responses to this event by secrecy strategy can be an important factor in the disease prevalence. results the experiences of patients with hiv/aids from stigma and discrimination led to exploring three main themes and nine subthemes. the main themes were mu...
