Searching for Radial Symmetry [PDF]

open access: yesi-Perception, 2017
Symmetry is ubiquitous in the natural world. Numerous investigations, dating back over one hundred years, have explored the visual processing of symmetry. However, these studies have been concerned with mirror symmetry, overlooking radial (or rotational)

Eulerian Dynamics in Multidimensions with Radial Symmetry [PDF]

open access: yesSIAM Journal on Mathematical Analysis, 2021
We study the global wellposedness of pressure-less Eulerian dynamics in multi-dimensions, with radially symmetric data. Compared with the 1D system, a major difference in multi-dimensional Eulerian dynamics is the presence of the spectral gap, which is difficult to control in general.

Minimax Density Estimation Under Radial Symmetry

open access: yesIEEE Access, 2023
This study illustrates a dimensionality reduction effect of radial symmetry in nonparametric density estimation. To deal with the class of radially symmetric functions, we adopt a generalized translation operation that preserves the symmetry structure ...

Radial symmetry in a chimeric glutamate receptor pore. [PDF]

open access: yesNat Commun, 2014
Ionotropic glutamate receptors comprise two conformationally different A/C and B/D subunit pairs. Closed channels exhibit fourfold radial symmetry in the transmembrane domain (TMD) but transition to twofold dimer-of-dimers symmetry for extracellular ligand binding and N-terminal domains.

Radial or Bilateral? The Molecular Basis of Floral Symmetry [PDF]

open access: yesGenes, 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. During evolution, several transcription factors have been recruited by the different developmental pathways in relation to the increase of plant complexity. The MYB

Radial symmetry and symmetry breaking for some interpolation inequalities [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2010
We analyze the radial symmetry of extremals for a class of interpolation inequalities known as Caffarelli-Kohn-Nirenberg inequalities, and for a class of weighted logarithmic Hardy inequalities which appear as limiting cases of the first ones.

Coulomb-Type Interaction under Lorentz Symmetry Breaking Effects [PDF]

open access: yesAdvances in High Energy Physics, 2017
Based on models of confinement of quarks, we analyse a relativistic scalar particle subject to a scalar potential proportional to the inverse of the radial distance and under the effects of the violation of the Lorentz symmetry.

Coordination of biradial-to-radial symmetry and tissue polarity by HD-ZIP II proteins. [PDF]

open access: yesNat Commun, 2021
Symmetry establishment is a critical process in the development of multicellular organs and requires careful coordination of polarity axes while cells actively divide within tissues.

From radial symmetry to fractal behavior of aggregation equilibria for repulsive–attractive potentials [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2021
For the interaction energy with repulsive–attractive potentials, we give generic conditions which guarantee the radial symmetry of the local minimizers in the infinite Wasserstein distance.
