Elementary Stability Considerations for Bowed-String Motion

Motion Perception, Elementary Mechanisms

Visual motion is essential for many aspects of biological function, including rapidly detecting predators and prey, navigating through the visual environment, and constructing a three-dimensional visual representation from two-dimensional retinal input. However, motion information is not provided by the instantaneous retinal signal, but has to be computed from temporal variations in luminance o...

Elementary motion detectors

A quick guide to the elementary motion detector- a model of how a simple neural circuit can detect visual motion, developed from work on insect vision but which seems also to be relevant to vertebrate visual systems.

Galois-stability for Tame Abstract Elementary Classes

We introduce tame abstract elementary classes as a generalization of all cases of abstract elementary classes that are known to permit development of stability-like theory. In this paper we explore stability results in this new context. We assume that K is a tame abstract elementary class satisfying the amalgamation property with no maximal model. The main results include: Theorem 0.1. Suppose ...

Markets and Hierarchies: Some Elementary Considerations

The principal purposes of this paper are to examine the factors which induce a shift of transactions from market to internal organization and, within internal organization, to explain the types of hierarchical relations that predictably emerge. It is generally acknowledged that a prima facie case for the development of nonmarket (or quasi-market) forms of economic organization can be said to ex...
