Geometric Shapes and Forms Associated With Three Kinds of Genetic Code Equivalences

Exploring Geometric Shapes with Touch

We propose a new technique to help users to explore geometric shapes without vision. This technique is based on a guidance using directional cues with a pin array. This is an alternative to the usual technique that consists of raising the pins corresponding to dark pixels around the cursor. In this paper we compare the exploration of geometric shapes with our new technique in unimanual and bima...

Three Levels of Semiosis: Three Kinds of Kinds

In philosophy, there is an as yet unresolved discussion on whether there are different kinds of kinds and what those kinds are. In particular, there is a distinction between indifferent kinds, which are unaffected by observation and representation, and interactive kinds, which respond to being studied in ways that alter the very kinds under study. This is in essence a discussion on ontologies a...

Strong matching of points with geometric shapes

Let P be a set of n points in general position in the plane. Given a convex geometric shape S, a geometric graph GS(P ) on P is defined to have an edge between two points if and only if there exists a homothet of S having the two points on its boundary and whose interior is empty of points of P . A matching in GS(P ) is said to be strong, if the homothets of S representing the edges of the matc...

Three kinds of lies.

Everyone is familiar with the famous quote from Benjamin Disraeli about lies and statistics, but we depend on statistics to evaluate the claims made by most articles published in the ophthalmic literature. The article in this issue by Lisboa et al (See page 1317) found that only 21% of the publications in 3 major ophthalmology journals in 2012 used simple descriptive statistics (percentages, me...
