A geometrical model for testing bilateral symmetry of bamboo leaf with a simplified Gielis equation [PDF]

open access: yesEcology and Evolution, 2016
The size and shape of plant leaves change with growth, and an accurate description of leaf shape is crucial for describing plant morphogenesis and development.

Generative network modeling reveals quantitative definitions of bilateral symmetry exhibited by a whole insect brain connectome [PDF]

open access: yeseLife, 2023
Comparing connectomes can help explain how neural connectivity is related to genetics, disease, development, learning, and behavior. However, making statistical inferences about the significance and nature of differences between two networks is an open ...

Bilateral symmetry of linear streptomycete chromosomes. [PDF]

open access: yesMicrob Genom, 2021
AbstractHere we characterise an uncommon set of telomeres fromStreptomyces rimosusATCC 10970, the parental strain of a lineage of one of the earliest-discovered antibiotic-producers. Following the closure of its genome sequence, we then compared unusual telomeres from this organism with the other five classes of replicon ends found amongst ...

Evaluation of roots, root canal morphology, and bilateral symmetry of maxillary first molars in a Syrian subpopulation using cone beam computed tomography [PDF]

open access: yesClinical and Experimental Dental Research, 2023
Objective Successful endodontic treatments require a comprehensive knowledge of the root canal anatomy, so this study aimed to investigate the number of roots, configurations of root canals, and their bilateral symmetry of maxillary first molars in the ...

Beyond bilateral symmetry: geometric morphometric methods for any type of symmetry [PDF]

open access: yesBMC Evolutionary Biology, 2011
Background Studies of symmetric structures have made important contributions to evolutionary biology, for example, by using fluctuating asymmetry as a measure of developmental instability or for investigating the mechanisms of morphological integration ...

CBCT analysis of mandibular position and bilateral symmetry in adult female patients with a deep overbite before and after flat bite plate treatment: a retrospective study [PDF]

open access: yesEuropean Journal of Medical Research
Aim To determine whether three-dimensional measurements can assess symmetry and mandibular position with greater accuracy than traditional two-dimensional measurements.

Bilateral symmetry detection on the basis of Scale Invariant Feature Transform. [PDF]

open access: yesPLoS ONE, 2014
The automatic detection of bilateral symmetry is a challenging task in computer vision and pattern recognition. This paper presents an approach for the detection of bilateral symmetry in digital single object images.

An Investigation of Bilateral Symmetry During Manual Wheelchair Propulsion. [PDF]

open access: yesFront Bioeng Biotechnol, 2015
Studies of manual wheelchair propulsion often assume bilateral symmetry to simplify data collection, processing and analysis. However, the validity of this assumption is unclear.

Evaluation of root canal morphology of premolar teeth using cone beam computed tomography: a retrospective study [PDF]

open access: yesBMC Oral Health
Background This study aimed to evaluate the root and canal morphology of maxillary and mandibular premolars using cone-beam computed tomography (CBCT) and to assess bilateral anatomical symmetry between contralateral teeth.

The effect of increasing heel height on lower limb symmetry during the back squat in trained and novice lifters

open access: yesBMC Sports Science, Medicine and Rehabilitation, 2020
Background Symmetry during lifting is considered critical for allowing balanced power production and avoidance of injury. This investigation assessed the influence of elevating the heels on bilateral lower limb symmetry during loaded (50% of body weight)
