THE QUANTITATIVE GENETICS OF FLUCTUATING ASYMMETRY [PDF]

Evolution, 2001
Fluctuating asymmetry (subtle departures from identical expression of a trait across an axis of symmetry) in many taxa is under stabilizing selection for reduced asymmetry. However, lack of reliable estimates of genetic parameters for asymmetry variation hampers our ability to predict the evolutionary outcome of this selection.

Entropy production and time-asymmetry in the presence of strong interactions [PDF]

, 2017
It is known that the equilibrium properties of open classical systems that are strongly coupled to a heat bath are described by a set of thermodynamic potentials related to the system's Hamiltonian of mean force.

Fluctuating asymmetry-indicator of what? [PDF]

Hereditas, 2002
In a population the optimal phenotype is promoted by buffering mechanisms that keep inter- and intra-individual variation low. A link exists between canalization, that controls phenotypic variation, and developmental stability, mostly measured as fluctuating asymmetry of bilateral traits (FA).

Facial symmetry and severity of gender dimorphism in its proportions in the isanzu people, traditional farmers of East Africa

Экспериментальная психология, 2015
In modern scientific literature on sexual selection, a significant place is occupied by scientific works that examine the relationship between indicators of fluctuating asymmetry of the face, the expression of sexual dimorphism and individual ...

Sphenoid bone is more asymmetrical than palatine bone among small ruminants

Journal of Applied Animal Research, 2021
A sample comprised by 53 dry modern skulls of adult small ruminants (sheep n = 36 and goat n = 17) from a comparative collection, absent of bony pathologies, was studied on their basal craniofacial aspect.

Aggregate Employment Fluctuations with Microeconomic Asymmetries [PDF]

American Economic Review, 1996
We provide a simple explanation for the observation from the U.S. manufacturing sector that the job destruction rate fluctuates more than the job creation rate. In our model, proportional plant-level costs of creating and destroying jobs cause shrinking plants to be more sensitive to aggregate shocks than growing plants.

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 ...

Perturbative and nonperturbative contributions to the strange quark asymmetry in the nucleon

, 2012
There are two mechanisms for the generation of an asymmetry between the strange and anti-strange quark distributions in the nucleon: nonperturbative contributions originating from nucleons fluctuating into virtual baryon-meson pairs such as $\Lambda K ...

Fluctuating asymmetry in dental and mandibular nonmetric traits as evidence for childcare sex bias in 19th/20th century Portugal. [PDF]

, 2017
Fluctuating asymmetry, often considered a measure of developmental instability, was studied in the dental morphological traits of 600 individuals from among the poorest sectors of society in 19th-20th century Portugal.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
