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.

The structural gene encoding the Rieske iron-sulfur protein from Thermus thermophilus HB8 has been cloned and sequenced. The gene encodes a protein of 209 amino acids that begins with a hydrophilic N-terminus followed by a stretch of 21 hydrophobic amino acids that could serve as a transmembrane helix. The remainder of the protein has a hydrophobicity pattern typical of a water-soluble protein....

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 ...

This paper describes how one can reduce the memory access time with pre-emphasis (PE) pulses even in non-volatile random-access memory. Optimum PE pulse widths and resultant minimum word-line (WL) delay times are investigated as a function of column address. The impact process variation constant WL, cell current, resistance deciding path on optimum discussed. WL modeled fitting curves address a...

Care of offspring by individuals other than the mother is ubiquitous in callitrichid primates. In spite of its widespread occurrence, however, there is considerable taxonomic variation in the timing and intensity of parental effort by breeding males and nonbreeding juvenile group members. These differences may be attributable to generic and specifies differences in the costs of reproduction for...

A determinantal expansion due to Okada is used to derive both a deformation of Weyl’s denominator formula for the Lie algebra sp(2n) of the symplectic group and a further generalisation involving a product of the deformed denominator with a deformation of flagged characters of sp(2n). In each case the relevant expansion is expressed in terms of certain shifted sp(2n)-standard tableaux. It is th...
