An Analytic Study of Two Probabilistic Models for Establishing <Emphasis Type="Italic">Ad Hoc</Emphasis> WLANs

A Characterisation of the Generalized Quadrangle <Emphasis Type="Italic">Q</Emphasis> (5, <Emphasis Type="Italic">q</Emphasis>) Using Cohomology

If a GQ S ′ of order (s, s) is contained in a GQ S of order (s, s2) as a subquadrangle, then for each point X of S\S ′ the set of points OX of S ′ collinear with X form an ovoid of S ′. Thas and Payne proved that if S ′ = Q(4, q), q even, and OX is an elliptic quadric for each X ∈ S\S ′, then S ∼= Q(5, q). In this paper we provide a single proof for the q odd and q even cases by establishing a ...

Partial Flocks of Non-Singular Quadrics in <Emphasis Type="Italic">PG</Emphasis>(2<Emphasis Type="Italic">r</Emphasis> + 1, <Emphasis Type="Italic">q</Emphasis>)

We generalise the definition and many properties of partial flocks of non-singular quadrics in PG(3, q) to partial flocks of non-singular quadrics in PG(2r + 1, q).

Suppressors <Emphasis Type="Italic">suaC 109 </Emphasis> and <Emphasis Type="Italic">suaA 101 </Emphasis> of <Emphasis Type="Italic">Aspergillus nidulans </Emphasis> alter the ribosomal phenotype <Emphasis Type="Italic">in vitro </Emphasis>

A new homologous, cell-free system for protein synthesis has been devised for use with ribosomes and elongation factors from Aspergillus nidulans. Ribosome preparations from strains with either the suaAlO1 or suaCl09 mutations have a higher misreading ratio (non-cognate:cognate amino acid incorporation) in the presence of hygromycin than controls. They can be classed as fidelity mutants. These ...

Schensted-Type Correspondences and Plactic Monoids for Types <Emphasis Type="Italic">B</Emphasis><Subscript>n</Subscript> and <Emphasis Type="Italic">D</Emphasis><Subscript>n</Subscript>

We use Kashiwara’s theory of crystal bases to study plactic monoids for Uq (so2n+1) and Uq (so2n). Simultaneously we describe a Schensted type correspondence in the crystal graphs of tensor powers of vector and spin representations and we derive a Jeu de Taquin for type B from the Sheats sliding algorithm.
