On the Successive Minima of Subbases of Low-Dimensional Lattices

Algebra Colloquium, 2014
In this paper we discuss the global optimality of vector lengths for lattice bases. By introducing a partial order on lattice bases and the concept of successive minimal basis (SMB for short), we show that any of its minimal elements is a general greedy-reduced basis, and its least element (if exists) is an SMB.

The Effect of Age on the Corneal Subbasal Nerve Plexus

Cornea, 2005
To measure subbasal nerve density and orientation in normal human corneas across a broad age range.Sixty-five normal corneas of 65 subjects were examined by using tandem scanning confocal microscopy. Ages of subjects ranged from 15 to 79 years (mean 46 +/- 19 years), with 5 subjects from each hemidecade. Subbasal nerve fiber bundles appeared as bright,

Generalized topologies generated by subbases

Acta Mathematica Hungarica, 2007
We investigate the generalized topology generated by a subbase for a topology, and consider its applications in the theory of rough sets.

The Connectedness Relative to a Subbase for the L-Fuzzy Topology

2009
The relative interior and closure in the L-fuzzy topology can represent the upper approximation set and the lower approximation set, respectively, which are the two most important concepts in the theory of covering generalized rough sets. In this report, we studied and introduced the concept of connectedness relative to a subbase. Such connectedness is

Comparative Study of Different Subbase Materials

Journal of Materials in Civil Engineering, 2006
California Bearing Ratio (CBR) and static and cyclic triaxial tests were conducted on the four most frequently encountered local materials—fly ash, coarse sand, stone dust, and river bed material (RBM)—for their use in the subbase layer of a flexible pavement.

A Hahn-Banach Theorem in Subbase Convexity Theory

Canadian Journal of Mathematics, 1980
In the last fifteen years, topology has shown up with an increasing interest in the use of closed subbases. Starting from Frink's internal characterization of complete regularity (Frink [6]), DeGroot and Aarts used closed subbases to obtain Hausdorff compactifications of completely regular spaces, thus giving a characterization of the latter in terms ...

Note on Separation Axiom Based on Subbase

2012
In this paper we first give the equivalent characterization on β − T 2 space. Then we introduce the definitions of regular-open set and regular-close set based on subbase and give their basic property. Furthermore, we define β − RC regular space and β − RC normal space and give their equivalent characterizations.

Compaction of Graded Aggregate Bases and Subbases

Transportation Engineering Journal of ASCE, 1977
Compaction of unbound, granular base and subbase layers in flexible pavement systems is reviewed. The distinction between density and compaction is related. The beneficial effect of increased density achieved through compaction on specific properties of grade aggregate mixtures, including strength and deformation characteristics, is demonstrated by the
