Dental Asymmetry in a Late Archaic and Late Prehistoric Skeletal Sample of the Ohio Valley Area
Dental Anthropology, 2003 Dental asymmetry (directional, anti-symmetry, and fluctuating) is analyzed in samples from two prehistoric Native American populations: a terminal Late Archaic population (3200-2700 BP) and a Late Prehistoric population (ca. 750 BP). Both directional and

Assessments of bilateral asymmetry with application in human skull analysis.
PLoS ONE, 2021 As a common feature, bilateral symmetry of biological forms is ubiquitous, but in fact rarely exact. In a setting of analytic geometry, bilateral symmetry is defined with respect to a point, line or plane, and the well-known notions of fluctuating ...

Cellular asymmetry and individuality in directional sensing [PDF]
Proceedings of the National Academy of Sciences, 2006 It is generally assumed that single cells in an isogenic population, when exposed to identical environments, exhibit the same behavior. However, it is becoming increasingly clear that, even in a genetically identical population, cellular behavior can vary significantly among cells.

Directional motion asymmetry in infant VEPs — which direction?
Vision Research, 2001 Monocular viewing during early infancy reveals asymmetries in optokinetic nystagmus (OKN) and visual evoked potentials (VEPs). This study investigates the VEP asymmetry to see if it is consistent in direction with the OKN asymmetry. Steady-state VEPs were recorded from infants (5-21 weeks) viewing gratings that underwent successive displacements in the

BMC Oral Health, 2023 Background Symmetry is critical in perceived attractiveness, especially in female faces. The palate determines the teeth’ alignment and supports facial soft tissues. Therefore, the study aimed to assess the effects of sex, orthodontic treatment, age, and

A Hand-Held Device Presenting Haptic Directional Cues for the Visually Impaired
Sensors, 2023 Haptic information is essential in everyday activities, especially for visually impaired people in terms of real-world navigation. Since human haptic sensory processing is nonlinear, asymmetric vibrations have been widely studied to create a pulling ...

Heritability of Directional Asymmetry inDrosophila melanogaster [PDF]
International Journal of Evolutionary Biology, 2009 Directional asymmetry (DA), the consistent difference between a pair of morphological structures in which the same side is always larger than the other, presents an evolutionary mystery. Although many paired traits show DA, genetic variation for DA has not been unambiguously demonstrated.

Co-clustering directed graphs to discover asymmetries and directional communities [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance This paper adds to the continuing and long-running interest in networks and network clustering. For directed networks, we propose the di-sim algorithm to capture asymmetries of connections and discover directional clusters. We illustrate this algorithm with three data examples: the Enron email

Anthropological Review, 2019 Asymmetry of bilateral anatomical structures is widely found in nature. Fluctuating asymmetry, i.e. mostly tiny random deviations from perfect symmetry in bilateral structures, is mainly interpreted within the framework of developmental instability. This
