Slanted symplectic quadrangles [PDF]

open access: yes, 2011
By "slanting" symplectic quadrangles W(F) over fields F, we obtain very simple examples of non-classical generalized quadrangles. We determine the collineation groups of these slanted quadrangles and their groups of projectivities.

Geometrical Constructions of Flock Generalized Quadrangles

open access: yesJournal of Combinatorial Theory, Series A, 2001
Let \({\mathbf K}\) be a quadratic cone of PG\((3,q)\) with vertex a point \(v\). A partition of \({\mathbf K}\setminus \{v\}\) into \(q\) irreducible conics is a flock of \({\mathbf K}.\) It was shown by J. A. Thas in 1987 that with a flock \({\mathcal F}\) there corresponds a set, called a \(q\)-clan, of \(q\) upper triangular matrices of order \(2\)

Automated Spin‐Assisted Layer‐by‐Layer Epitaxy Produces Highly Oriented Mixed‐Linker MOF Thin Films

open access: yesAngewandte Chemie International Edition, EarlyView.
An automated spin‐assisted layer‐by‐layer growth method enables rapid fabrication of highly oriented Zn2BDC2DABCO metal‐organic framework thin films under ambient conditions. Correlative characterization confirms excellent reproducibility, uniform film formation, and exceptional out‐of‐plane orientation exceeding 85%.

Postcranial anatomy and osteohistology of an early prozostrodont cynodont from the Upper Triassic of Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

On finite elation generalized quadrangles with symmetries

open access: yes, 1996
We study the structure of finite groups G which act as elation groups on finite generalized quadrangles and contain a full group of symmetries about some line through the base point.

Connected orbits in topological generalized quadrangles

open access: yes, 1995
We study generalized quadrangles. After an investigation of the subgeometries that are generated by arbitrary sets of vertices, we consider orbits of connected subgroups of the automorphism group of topological generalized quadrangles.
