Some New Observations on 'Because (of)'

Because (of) is ambiguous between a ‘reason’ and a ‘plain cause’ interpretation. Presenting a semantic analysis within the framework of Discourse Representation Theory, I argue that because (of) always denotes a causal relation between causing facts and caused entites of various sorts and that its interpretational variance is dependent on the ontological nature of the caused entity. Finally, I ...

Some New Examples with Quasi-positive Curvature

As a means to better understanding manifolds with positive curvature, there has been much recent interest in the study of nonnegatively curved manifolds which contain a point at which all 2-planes have positive curvature. We show that there are generalisations of the well-known Eschenburg spaces together with quotients of S×S which admit metrics with this property. It is an unfortunate fact tha...

Some new observations on L forms of bacteria.

The first, part of the paper contains observations on the development of the L forms of Proteus on the surface of liquid media and the properties of the cultures so obtained. This type of culture was described by Tulasne (1950). These cultures provide L forms in masses which can be separated easily from the media. Our interest was attracted especially by the observation that these cultures diff...

Some New Observations on Interpolation in the Spectral Unit Ball

We present several results associated to a holomorphic-interpolation problem for the spectral unit ball Ωn, n ≥ 2. We begin by showing that a known necessary condition for the existence of a O(D; Ωn)-interpolant (D here being the unit disc in C), given that the matricial data are non-derogatory, is not sufficient. We provide next a new necessary condition for the solvability of the two-point in...
