South Bend landlord Mark Kramer hired a private security company Friday to patrol his more than 150 properties after recent car break-ins. “We’ve had some car breakins and one is too many as far as I’m concerned,” he said. “I just haven’t had much cooperation with the police d epartm en t when we’ve had problems. ... Safety is very im portant, so I made the decision to hire a pri­ vate company....

A new species of Tozzita Kramer, 1964, Tozzita bifida sp. nov., is described and illustrated. The new species can be distinguished from the other species of the genus by the following characteristics: (1) forewing with commissural brown band; (2) pygofer with dentiform process on ventral margin and apex not spatulate; (3) subgenital plates with macroseta at apex; (4) style with preapical lobe d...

Let Γ denote a distance-regular graph with diameter D ≥ 3, intersection numbers ai, bi, ci and Bose-Mesner algebra M. For θ ∈ C ∪∞ we define a 1 dimensional subspace of M which we call M(θ). If θ ∈ C then M(θ) consists of those Y in M such that (A−θI)Y ∈ CAD, where A (resp. AD) is the adjacency matrix (resp. Dth distance matrix) of Γ. If θ = ∞ then M(θ) = CAD. By a pseudo primitive idempotent f...

Generalized table algebras were introduced in Arad, Fisman and Muzychuk (Israel J. Math. 114 (1999), 29–60) as an axiomatic closure of some algebraic properties of the Bose-Mesner algebras of association schemes. In this note we show that if all non-trivial degrees of a generalized integral table algebra are even, then the number of real basic elements of the algebra is bounded from below (Theo...

I report on a documented dieback in spicebush, Lindera benzoin, after the winter of 1993-1994 in two mature deciduous forest stands in southwestern Ohio. The study compares differences between 67 ha Hueston Woods and 5.2 ha Kramer Woods and examines spatial patterns of decline in Kramer Woods. Local daily minimum temperatures in January 1994 were among the coldest on record since 1889The shrub ...

We study the four-weight spin models (W1, W2, W3, W4) introduced by Eiichi and Etsuko Bannai (Pacific J. of Math, to appear). We start with the observation, based on the concept of special link diagram, that two such spin models yield the same link invariant whenever they have the same pair (W1, W3), or the same pair (W2, W4). As a consequence, we show that the link invariant associated with a ...
