Holey barrier
Endothelial tight junctions (TJs)* are an important functional part of the blood-brain barrier (BBB). In this issue, Nitta et al. (2003) demonstrate that claudin-5, a transmembrane protein of TJs, is a critical determinant of BBB permeability in mice. Unexpectedly, knockout of claudin-5 did not result in a general breakdown of TJs but in a selective increase in paracellular permeability of smal...
متن کاملHoley factorizations
Holey factorizations of Kv1,v2,...,vn are a basic building block in the construction of Room frames. In this paper we give some necessary conditions for the existence of holey factorizations and give a complete enumeration for nonisomorphic sets of orthogonal holey factorizations of several special types.
متن کاملTapered Holey Fiber
Adiabatically tapered holey fibers are shown to be potentially useful for guided-wave spot-size and numerical aperture conversion. Conditions for adiabaticity and design guidelines are provided in terms of the effective index model. We also present finite-difference time-domain calculations of down-tapered holey fiber, showing that large spot size conversion factors are obtainable with minimal ...
متن کاملHoley Segre Varieties
Holey Segre varieties are introduced, which generalize classical Segre varieties and whose existence is suggested by the fact that any non-prime finite field contains proper subfields. More precisely, a holey Segre variety is the tensor product PG(n, q) ⊗ PG(m, qk ). An algebraic description of such an object is given and its structure is investigated. Furthermore, special choices of the parame...
متن کاملTiling rectangles with holey polyominoes
We present a new type of polyominoes that can have transparent squares (holes). We show how these polyominoes can tile rectangles and we categorise them according to their tiling ability. We were able to categorise all but 7 polyominoes with 5 or fewer visible squares.
