Potential chromosomal introgression barriers revealed by linkage analysis in a hybrid of Pinus massoniana and P. hwangshanensis

open access: yesBMC Plant Biology, 2010
Background Exploring the genetic mechanisms underlying speciation is a hot topic in modern genetics and evolutionary studies. Distortion of marker transmission ratio is frequently ascribed to selection against alleles that cause hybrid incompatibility ...

The Role of Urban Sustainability Mechanisms in Raising the Efficiency and Organization of Urban Management in Egyptian Cities, A Case Study (El-Salam District, Port Said) [PDF]

open access: yesPort Said Engineering Research Journal, 2023
The rapid changes that our world witnessed had an impact on controlling the Egyptian planning and urbanization system, and we also do not overlook the shortcomings of some legislation, which resulted in a distortion in the urban environment with the ...

Distortion-Product Otoacoustic Emissions as a Screening Tool for Noise-Induced Hearing Loss. [PDF]

open access: yes, 2018
Noise-induced hearing loss includes both temporary (TTS) and permanent (PTS) threshold shifts. Although TTS and PTS have many similarities, their underlying mechanisms are different.

Investigation on reason of range profile distortion of plasma sheath target

open access: yesThe Journal of Engineering, 2019
The range profile of the plasma sheath target is always found to be distorted when using the linear frequency modulation signal as the radar detection signal. As a result, the detection and tracking of the target became hard, or even failure. Here, three

Energy Landscape Distortions and the Mechanical Unfolding of Proteins [PDF]

open access: yesBiophysical Journal, 2005
Molecular simulations and an energy landscape analysis are used to examine the stretching of a model protein. A mapping of the energy landscape shows that stretching the protein causes energy minima and energy barriers to flatten out and disappear, and new energy minima to be created.

The Flashed Face Distortion Effect Does Not Depend on Face-Specific Mechanisms

open access: yesScientific Reports, 2019
When normal faces are rapidly presented in the visual periphery, they are perceived as grotesque and distorted. This phenomenon, “The flashed-face distortion effect” (FFDE) is a powerful illusion that may reveal important properties of how faces are ...

Peeking behind the ordinal curtain: Improving distortion via cardinal queries [PDF]

open access: yes, 2020
The notion of distortion was introduced by Procaccia and Rosenschein (2006) to quantify the inefficiency of using only ordinal information when trying to maximize the social welfare.

Inferred retinal mechanisms mediating illusory distortions

open access: yesVisual Neuroscience, 2004
The Zoellner illusion is a geometric distortion occurring when nonorthogonal inducing lines appear to tilt veridically parallel bars. The retinal pathways contributing to such illusions are unknown. The goal of this experiment was to investigate the retinal origin of the illusion. This was accomplished by determining the contrast gain for illusion
