All interventions differ, although some are more different than others

When some are more equal than others.

Some Terms are more Interchangeable than Others

This paper describes the work done by the Information Retrieval Research Group at Océ Technologies B.V., for the Cross-Language Evaluation Forum (CLEF) 2001. We have participated in the Dutch Monolingual task and submitted three runs. In this paper we introduce a new method for relevance computation using two new query operators. This method is meant to be applied to Multilingual Retrieval in t...

All PSPACE-Complete Planning Problems Are Equal but Some Are More Equal than Others

Complexity analysis of planning is problematic. Even very simple planning languages are PSPACE-complete, yet cannot model many simple problems naturally. Many languages with much more powerful features are also PSPACE-complete. It is thus difficult to separate planning languages in a useful way and to get complexity figures that better reflect reality. This paper introduces new methods for comp...

All muscle satellite cells are equal, but are some more equal than others?

Skeletal muscle is an accessible adult stem-cell model in which differentiated myofibres are maintained and repaired by a self-renewing stem-cell compartment. These resident stem cells, which are known as satellite cells, lie on the surface of the muscle fibre, between the plasmalemma and overlying basal lamina. Although they are normally mitotically quiescent in adult muscle, satellite cells c...
