Developmental Dynamics, EarlyView.Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Propagating left/right asymmetry in the zebrafish embryo: one-dimensional model [PDF]
arXiv, 2011 During embryonic development in vertebrates, left-right (L/R) asymmetry is reliably generated by a conserved mechanism: a L/R asymmetric signal is transmitted from the embryonic node to other parts of the embryo by the L/R asymmetric expression and diffusion of the TGF-$\beta$ related proteins Nodal and Lefty via propagating gene expression fronts in ...

Scaling Relations in the Vortex State of Nodal Superconductors [PDF]
, 2005 In contrast to multigap superconductors (e.g. MgB$_{2}$), the low-temperature properties of nodal superconductors are dominated by nodal excitations. Here we extend for a variety of nodal superocnductors the earlier work by Simon and Lee and K\"ubert and Hirschfeld.

Molecular anatomy of emerging Xenopus left–right organizer at successive developmental stages
Developmental Dynamics, EarlyView.Abstract Background Vertebrate left–right symmetry breaking is preceded by formation of left–right organizer. In Amphibian, this structure is formed by gastrocoel roof plate, which emerges from superficial suprablastoporal cells. GRP is subdivided into medial area, which generates leftward flow by rotating monocilia and lateral Nodal1 expressing areas,

Graph Estimation From Multi-attribute Data [PDF]
arXiv, 2012 Many real world network problems often concern multivariate nodal attributes such as image, textual, and multi-view feature vectors on nodes, rather than simple univariate nodal attributes. The existing graph estimation methods built on Gaussian graphical models and covariance selection algorithms can not handle such data, neither can the theories ...

Developmental Dynamics, EarlyView.Abstract Background Mouse nodal immotile cilia mechanically sense the bending direction for left–right (L–R) determination and activate the left‐side‐specific signaling cascade, leading to increased Nodal activity. Asymmetric distribution of Pkd2, a crucial channel for L–R determination, on immotile cilia has been reported recently. However, the causal

Evolutionary homology on coupled dynamical systems [PDF]
arXiv, 2018 Time dependence is a universal phenomenon in nature, and a variety of mathematical models in terms of dynamical systems have been developed to understand the time-dependent behavior of real-world problems. Originally constructed to analyze the topological persistence over spatial scales, persistent homology has rarely been devised for time evolution ...

On the Nodal Count Statistics for Separable Systems in any Dimension [PDF]
, 2012 We consider the statistics of the number of nodal domains aka nodal counts for eigenfunctions of separable wave equations in arbitrary dimension. We give an explicit expression for the limiting distribution of normalised nodal counts and analyse some of its universal properties.
