On covariant non-constancy of distortion and inversed distortion tensors [PDF]

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2022
The paper deals with covariant constancy problem for tensors and pseudotensors of an arbitrary rank and weight in an Euclidean space. Requisite preliminaries from pseudotensor algebra and analysis are given.

Room reflections and constancy in speech-like sounds: within-band effects [PDF]

, 2010
The experiment asks whether constancy in hearing precedes or follows grouping. Listeners heard speech-like sounds comprising 8 auditory-filter shaped noise-bands that had temporal envelopes corresponding to those arising in these filters when a speech ...

The weed species composition in a reed canary grass (Phalaris arundinacea L.) plantation for energy purposes depending on its age

Acta Agrobotanica, 2014
The present experiment, carried out in nine production fields of reed canary grass (Phalaris arundinacea) grown for energy purposes, evaluated the effect of plantation age on the occurrence and species composition of weeds.

Lightness constancy: Object identity and temporal integration [PDF]

Psihologija, 2008
Studies of lightness constancy typically involve the comparison of two objects of the same shade that have been placed under different illuminations. In this study, we introduce factors such as object identity and immediate prior experience to measure ...

Lightness constancy: ratio invariance and luminance profile [PDF]

, 2009
The term simultaneous lightness constancy describes the capacity of the visual system to perceive equal reflecting surfaces as having the same lightness despite lying in different illumination fields.

The Planck length and the constancy of the speed of light in five dimensional space parametrized with two time coordinates [PDF]

, 2017
In relativity and quantum field theory, the vacuum speed of light is assumed to be constant; the range of validity of general relativity is determined by the Planck length.

Binaural Loudness Constancy [PDF]

, 2016
In binaural loudness summation, diotic presentation of a sound usually produces greater loudness than monaural presentation. However, experiments using loudspeaker presentation with and without earplugs find that magnitude estimates of loudness are little altered by the earplug, suggesting a form of loudness constancy.

Predicting how pollinator behavior causes reproductive isolation

Ecology and Evolution, 2022
Pollinator behavior is an important contributor to plants speciation, yet how variation in pollinator behavior causes variation in reproductive isolation (RI) is largely uncharacterized.
