In the present article, we highlight the diversity of mechanical clamps, some of them topological in nature, that have been found by making surveys of mechanostability of approximately 18000 proteins within structure-based models. The existence of superstable proteins (with the characteristic unfolding force in the region of 1000 pN) is predicted.

This article deals with a two-parameter family of piecewise smooth unimodal maps with one break point. Using superstable cycles and their symbolic representation we describe the structure of the periodicity regions of the 2D bifurcation diagram. Particular attention is paid to the bistability regions corresponding to two coexisting attractors, and to the border-collision bifurca-

The aim of this paper is to show that under some mild conditions a functional equation of multiplicative $(alpha,beta)$-derivation is superstable on standard operator algebras. Furthermore, we prove that this generalized derivation can be a continuous and an inner $(alpha,beta)$-derivation.

An omitting types theorem for countable models of superstable theories containing an infinite set of indiscernibles is proved. Various corollaries and applications are given. 1. One of the most useful ways that the model theorist has for controlling models is to attempt to specify the element types that models realize and omit. In this paper we present an omitting types theorem which seems well...

In [3] an uncountably categorical group is constructed that has a non-locallymodular geometry and does not allow the interpretation of a eld. We consider a system of elementary axioms ful lled by some special subgroups of the group above. We show that is complete, stable, but not superstable. It is even not a R-group in the sense of [10].

This paper considers synchronous phenomena from switchcoupled relaxation oscillators. This system exhibits a variety of interesting superstable synchronous phenomena. Using a hybrid return map, we can analyze the phenomena almost completely. Using a simple circuit, typical phenomena are verified in the laboratory.
