Thermal stability and protein structure
Biochemistry, 1979Amino acid sequences have been compared for thermophilic and mesophilic molecules of ferredoxin, glyceraldehyde-3-phosphate dehydrogenase, and lactate dehydrogenase. It is shown that Gly, Ser, Ser, Lys, and Asp in mesophiles are generally substituted by Ala, Ala, Thr, Arg, and Glu, respectively, in thermophiles.

Structural stability and catastrophes [PDF]
Economics Bulletin, 2012 We show that, in a pure exchange smooth economy, a redistribution of endowments involving singular economies can be supported by a unique and continuous path of supporting equilibrium price vectors if this redistribution is the projection of a path on the equilibrium manifold transversal to the set of critical equilibria.

Electronic Structure and Stability of Pentaorganosilicates
Journal of the American Chemical Society, 2006The exceptional stability of recently reported pentaorganosilicates is investigated by bond energy analyses. Experimental coupling constants are used to probe their electronic structure, entailing bonds with mixed ionic-covalent character. Our analyses reconfirm that the axial bonds are more prone to heterolytic cleavage than are the equatorial bonds ...

The Structure and Stability of Thermolysin
1976Thermolysin is an extracellular proteolytic enzyme isolated from Bacillus thermoproteolyticus (Endo, 1962). The enzyme is quite thermostable, retaining over half of its activity after being heated in an aqueous solution for an hour at 80°C, while at 65°C practically no inactivation occurs (Endo, 1962; Matsubara, 1967).

A Structural Stability Theorem
The Annals of Mathematics, 1971precise definition of structural stability given in ? 5 is somewhat stronger; it demands that the conjugacy 9q can be found within an arbitrary CO neighborhood of the identity when g is sufficiently close to f.) The idea of this definition is that qualitative properties of structurally stable diffeomorphisms are unchanged by small C' perturbations. The

On the Stability of Structured Prediction
2015Many important applications of artificial intelligence---such as image segmentation, part-of-speech tagging and network classification---are framed as multiple, interdependent prediction tasks. These structured prediction problems are typically modeled using some form of joint inference over the outputs, to exploit the relational dependencies.

The notion of structural stability was first introduced by the Russian math- ematicians Alexandr Andronov and Lev Pontryagin (cf. Andronov and Potryangin 1937). However, there are traces of such a concept in the work of the French math- ematician Henry Poincaré (cf. Poincaré 1880).

Easily, almost naturally, we approach the political as a coherent purposive practice, or at least as a distinctive mode of patterned behaviour, in either case with theories inherent in or attached vicariously to it. Understandings of the political too numerous and unnecessary to mention tell us that the political is about government, or power relations,
