Identity and self consciousness: two separate phenomena

Identity, personality and self-consciousness are often seen in cognitive science as almost the same cognitive capacity. In this paper we will justify an alternative and in many ways opposite opinion: that identity, at least in its most basic way, is a non-exclusive protocultural factor that requires cognitive capacities that are linked to social competence and to organism cooperation, and that ...

Polio: Two New Points

Points in Two Polytopes

We propose a separating-hyperplane algorithm for finding a nearest pair of points in two polytopes, where each polytope is expressed as the convex hull of given points in a Euclidian space. The proposed algorithm is an extension of the authors dual algorithm for finding t.he minimum-norm point in a polytope.

Microleakage of Bulk-Fill Composites at Two Different Time Points

Objectives: Microleakage is the main concern in composite restorations. This study aimed to compare the microleakage of two bulk-fill and one conventional composite at two different time points. Methods: Class II cavities were prepared in 60 premolar teeth and divided into six groups of 20. Groups 1 and 4 were incrementally filled with Grandio composite. Groups 2 and 5 were filled with X-tra...

Two Results on Special Points

We show that there is a nowhere ccc σ-compact space which has a remote point. We show that it is consistent to have non-compact σ-compact separable space X such that every point of the remainder is a limit of a countable discrete subset of non-isolated points of X. This example shows that one cannot prove in ZFC that every locally compact non-compact space has discrete weak P -points.
