Memo1-Mediated Tiling of Radial Glial Cells Facilitates Cerebral Cortical Development.
Neuron, 2019 Polarized, non-overlapping, regularly spaced, tiled organization of radial glial cells (RGCs) serves as a framework to generate and organize cortical neuronal columns, layers, and circuitry.

Ricci Curvature on Polyhedral Surfaces via Optimal Transportation
Axioms, 2014 The problem of correctly defining geometric objects, such as the curvature, is a hard one in discrete geometry. In 2009, Ollivier defined a notion of curvature applicable to a wide category of measured metric spaces, in particular to graphs.

Quantifying Glial-Glial Tiling Using Automated Image Analysis in Drosophila
Frontiers in Cellular Neuroscience, 2022 Not only do glia form close associations with neurons throughout the central nervous system (CNS), but glial cells also interact closely with other glial cells.

Maximal equicontinuous factors and cohomology for tiling spaces [PDF]
, 2012 We study the homomorphism induced on cohomology by the maximal equicontinuous factor map of a tiling space. We will see that this map is injective in degree one and has torsion free cokernel.

Single-component quasicrystalline nanocrystal superlattices through flexible polygon tiling rule
Science, 2018 Quantum dots line up as a quasicrystal Quasicrystals have rotational symmetry but no long-range order. Although several materials have quasicrystalline order, examples of quasicrystalline superlattices formed from different types of particles are rare ...

Discrete Mathematics & Theoretical Computer Science, 2010 We contribute to combinatorics and algorithmics of words by introducing new types of periodicities in words. A tiling period of a word w is partial word u such that w can be decomposed into several disjoint parallel copies of u, e.g.

Tiling of the five-fold surface of Al(70)Pd(21)Mn(9)
, 2001 The nature of the five-fold surface of Al(70)Pd(21)Mn(9) has been investigated using scanning tunneling microscopy. From high resolution images of the terraces, a tiling of the surface has been constructed using pentagonal prototiles. This tiling matches

GEOMETRIC REDESIGN OF THE SUBDIVIDED SURFACE OF CC II: APPLICATION IN ARCHITECTURE
Journal of Industrial Design and Engineering Graphics, 2019 The concave polyhedral surface of CC II can be used as a structural template for architectural design of domes, roofs or other covering or stand-alone structures.
