Microtubules suppor t nuclear nonproliferation arrangement L aporte et al. describe how a mi-crotubule array reorganizes the nucleus to aid the survival of qui-escent budding yeast. Eukaryotic cells undergo a dramatic rearrangement when they temporarily exit the cell cycle and become qui-escent. Budding yeast, for example, reorganize their actin cyto-skeleton into immobile structures called act...

We define a double pseudoline as a simple closed curve in the open Möbius band homotopic to the double of its core circle, and we define an arrangement of double pseudolines as a collection of double pseudolines such that every pair crosses in 4 points – the crossings being transversal – and induces a cell decomposition of the Möbius band whose 2-dimensional cells are 2-balls, except the unboun...

Manin and Schechtman defined the discriminantal arrangement of a generic hyperplane arrangement as a generalization of the braid arrangement. This paper shows their construction is dual to the fiber zonotope construction of Billera and Sturmfels, and thus makes sense even when the base arrangement is not generic. The hyperplanes, face lattices and intersection lattices of discriminantal arrange...

Small groups which form for teaching and learning process would have substantial outcomes if manage properly. Evidence suggests that environment and seating arrangement of the learners would have considerable impacts on the success of a facilitator to properly use from the dynamics of the group. The aim of the present article is therefore to discuss the appropriate environment and seating arran...

Optimizing interconnection networks is a prime object in switching schemes. In this work the authors present a novel approach for obtaining a required channel arrangement in a multi-stage interconnection network, using a new concept – a fundamental arrangement. The fundamental arrangement is an initial N-1 stage switch arrangement that allows obtaining any required output channel arrangement gi...

ATP-gated ionotropic receptors (P2X receptors) are distributed widely in the nervous system. For example, a hetero-oligomeric receptor containing both P2X2 and P2X3 subunits is involved in primary afferent sensation. Each subunit has two membrane-spanning domains. We have used disulfide bond formation between engineered cysteines to demonstrate close proximity between the outer ends of the firs...
