Scientific Reports, 2023 As many human organs exist in pairs or have symmetric appearance and loss of symmetry may indicate pathology, symmetry evaluation on medical images is very important and has been routinely performed in diagnosis of diseases and pretreatment evaluation ...

Aging and Bilateral Symmetry Detection [PDF]
The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 2002 The salience of bilateral symmetry varies as a function of the orientation of the symmetry axis. Vertical symmetry is most salient, followed by horizontal and then oblique orientations. We tested symmetry detection in different age groups to determine whether performance of this intermediate-level visual task is affected by normal, nonpathological ...

Radial or bilateral? The molecular basis of floral symmetry. [PDF]
, 2020 In the plant kingdom, the flower is one of the most relevant evolutionary novelties. Floral symmetry has evolved multiple times from the ancestral condition of radial to bilateral symmetry.

Patterns of Symmetry Expression in Angiosperms: Developmental and Evolutionary Lability
Frontiers in Ecology and Evolution, 2020 Variation in flower symmetry is a remarkable aspect of flowering plant diversity. Multiple evolutionary transitions from an ancestral form of radial symmetry to bilateral symmetry and reversals from bilateral to radial symmetry have occurred during ...

The manoeuvrability hypothesis to explain the maintenance of bilateral symmetry in animal evolution
Biology Direct, 2012 Background The overwhelming majority of animal species exhibit bilateral symmetry. However, the precise evolutionary importance of bilateral symmetry is unknown, although elements of the understanding of the phenomenon have been present within the ...

Fast Radial and Bilateral Symmetry Detection Using Inverted Gradient Hash Maps
EAI Endorsed Transactions on Context-aware Systems and Applications, 2017 This paper presents a fast and novel algorithm for both radial and bilateral symmetry detection based on inverted gradient hash maps (IGHMs). A hash map is an associative array that stores image gradient magnitudes and orientations in the form of an ...

Floral symmetry affects bumblebee approach consistency in artificial flowers
Journal of Pollination Ecology, 2016 Bilateral symmetry has evolved from radial symmetry in several floral lineages, and multiple hypotheses have been proposed to account for the success of this floral plan.

A Retrospective Study of Roots and Root Canal Morphology in Mandibular Premolars using Cone Beam Computed Tomography in Delhi-NCR [PDF]
Journal of Clinical and Diagnostic Research, 2021 Introduction: The anatomical heterogeneity of mandibular premolars has always been considered an enigma and it makes them potentially prone to high rates of endodontic failure.
