Some isomorphically polyhedral orlicz sequence spaces [PDF]
A Banach space is polyhedral if the unit ball of each of its finite dimensional subspaces is a polyhedron. It is known that a polyhedral Banach space has a separable dual and is $c_0$-saturated, i.e., each closed infinite dimensional subspace contains an isomorph of $c_0$.

Almost Locally Polyhedral Curves in Euclidean n-Space [PDF]
Fox and Artin [2] have given examples of wild arcs and curves in E3 which fail to be locally polyhedral at only one or two points. It is shown in this paper that no such "simple" examples of wild curves are to be expected in dimensions higher than three.

Cyclohexane plastic phase I: single-crystal diffraction images and new structural model
The plastic phase of cyclohexane (polymorph I) was studied by Kahn and co-workers, without achieving a satisfactory determination of the atomic coordinates [Kahn et al. (1973). Acta Cryst. B29, 131–138].

Intersection Properties of Balls in Banach Spaces
We introduce a weaker notion of central subspace called almost central subspace, and we study Banach spaces that belong to the class (GC), introduced by Veselý (1997). In particular, we prove that if is an almost central subspace of a Banach space such

Background RNA secondary structure prediction is a compute intensive task that lies at the core of several search algorithms in bioinformatics. Fortunately, the RNA folding approaches, such as the Nussinov base pair maximization, involve mathematical ...

Predictive modeling in a polyhedral optimization space [PDF]
It has been shown that the right set of polyhedral optimizations can make a significant difference in the running time of a program. However, the number of alternatives for a program transformed with polyhedral optimizations can be enormous. Thus, it is often impossible to iterate over a significant fraction of the entire space of polyhedral ...

This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Novel structures for optimal space partitions
Partitioning space into polyhedra with a minimum total surface area is a fundamental question in science and mathematics. In 1887, Lord Kelvin conjectured that the optimal partition of space is obtained with a 14-faced space-filling polyhedron, called ...

Certified polyhedral decompositions of collision-free configuration space
Understanding the geometry of collision-free configuration space (C-free) in the presence of Cartesian-space obstacles is an essential ingredient for collision-free motion planning. While it is possible to check for collisions at a point using standard algorithms, to date no practical method exists for computing C-free regions
