New partial geometries constructed from old ones

Partial Geometries

The main purpose of this paper is to survey recent results on partial geometries. I t is now twenty years since Bose [1] introduced the concept of a partial geometry in order to study large cliques in strongly regular graphs. Several strong necessary conditions for the existence of strongly regular graphs also have consequences for the existence question for partial geometries. We give the nece...

Finding 'new' occupational diseases and trends in 'old' ones.

Strategies for the reduction of risk to the health of workers, as well as the population in general, rely on the collection, analysis and interpretation of valid data to study work-related ill-health in relation to its determinants. In the developed world, through advances in occupational medicine and changing societal attitude reflected in legislation, the scourges of many occupational disease...

Concepts for Liver Segment Classification: Neither Old Ones nor New Ones, but a Comprehensive One

Concepts dealing with the subdivision of the human liver into independent vascular and biliary territories are applied routinely in radiological, surgical, and gastroenterological practice. Despite Couinaud's widely used eight-segments scheme, opinions on the issue differ considerably between authors. The aim of this article is to illustrate the scientific basis for understanding and harmonizin...

Ebola therapy: Developing new drugs or repurposing old ones?

Learning New Compositions from Given Ones

In this paper, we study the problem of "learning new compositions of words from given ones with a specific syntactic structure, e.g., A-N or V-N structures. We first cluster words according to the given compositions, then construct a cluster-based compositional frame for each word cluster, which contains both new and given compositions relevant with the words in the cluster. In contrast to othe...
