Auditory discrimination of frequency ratios: The octave singularity. [PDF]
Journal of Experimental Psychology: Human Perception and Performance, 2013 Sensitivity to frequency ratios is essential for the perceptual processing of complex sounds and the appreciation of music. This study assessed the effect of ratio simplicity on ratio discrimination for pure tones presented either simultaneously or sequentially.

Frequency ratios and the discrimination of pure tone sequences [PDF]
Perception & Psychophysics, 1994 We examined the effect of frequency ratios on the discrimination of patterns of alternating pure tones (ABABA). Listeners heard a repeating pattern presented in transposition (same frequency ratios between successive tones, different absolute frequencies) and were required to indicate when the pattern changed (different frequency ratios and absolute ...

The Poisson Ratio of the Cellular Actin Cortex Is Frequency Dependent [PDF]
Biophysical Journal, 2020 Cell shape changes are vital for many physiological processes such as cell proliferation, cell migration and morphogenesis. They emerge from an orchestrated interplay of active cellular force generation and passive cellular force response - both crucially influenced by the actin cytoskeleton.

High‐Frequency Power Ratio of Breathy Voice [PDF]
The Laryngoscope, 1992 AbstractDigital technological advances have made detailed voice analysis possible. This report proposes, with the use of such equipment, a new method of quantifying differences in the high‐frequency content of normal and breathy voices.The high‐frequency power ratio, a ratio of high‐frequency power versus total power, was calculated as the lower limit ...

Haplodiploidy, sex-ratio adjustment, and eusociality. [PDF]
, 2013 Hamilton's "haplodiploidy hypothesis" holds that inflated sororal relatedness has promoted altruistic sib rearing in haplodiploids, potentially explaining their apparent predisposition to eusociality.

A Combined Method for Preparation of Landslide Susceptibility Map in Izmir (Türkiye)
Applied Sciences, 2022 Landslide susceptibility maps (LSMs) have been used frequently by researchers for many years in prediction of the occurrence of landslides. Since many landslides have occurred there in the past, Izmir, which is the third largest city of Türkiye, was ...
