Nuclear bars and blue nuclei within barred spiral galaxies
M. Shaw, D. Axon, R. Probst +1
Multicolour near IR photometry for a sample of 32 large barred spiral galaxies is presented. By applying ellipse fitting techniques, we identify significant isophote twists with re…
N-Gram Cluster Identification During Empirical Knowledge Representation Generation
Robin Collier
This paper presents an overview of current research concerning knowledge extraction from technical texts. In particular, the use of empirical techniques during the identification a…
Reference Resolution Using Semantic Patterns in Japanese Newspaper Articles
Takahiro Wakao
Reference resolution is one of the important tasks in natural language processing. In this paper, the author first determines the referents and their locations of "dousha", literal…
Phase Separation and Superconductivity in the Copper Oxide Chain
C. Vermeulen, W. Barford, E. R. Gagliano
The phase diagram of the copper-oxide chain as a function of density and the nearest-neighbour Coulomb interaction, V, is determined. Phase separation takes place above a critical…
Strong Coupling Descriptions of High Temperature Superconductors: Electronic Attraction from a Repulsive Potential
W. Barford, M. W. Long
We consider the effect of the nearest neighbour copper-oxygen repulsion, V, when coupled to the charge transfer resonances Cu2+ to Cu3+ and Cu2+ to Cu+ in the high temperature cupr…
One Dimensional Continuum Falicov-Kimball Model in the Strongly Correlated Limit
R. J. Bursill
In this paper we study the thermodynamics of the one dimensional continuum analogue of the Falicov-Kimball model in the strongly correlated limit using a method developed by Salsbu…
