On the hyperstability of time-varying blocks [PDF]

open access: possibleIEEE Transactions on Automatic Control, 1970
The hyperstability of linear time-varying discrete blocks is studied. Sufficient conditions for hyperstability are obtained for special classes of multiple and simple blocks.

Experimental demonstration of catch hyperstability from habitat aggregation, not effort sorting, in a recreational fishery

Canadian Journal of Fisheries and Aquatic Sciences, 2020
The relationship between angler catch rates and fish abundance can contribute to or hinder sustainable exploitation of fisheries depending on whether catch rates are proportional to fish abundance or are hyperstable.

On the Hyers–Ulam stability and hyperstability of a generalized quadratic functional equation in n-Banach spaces

, 2021
In this paper, we establish some Hyers–Ulam stability and hyperstability results of the following functional equation [Formula: see text] in the class of functions from an abelian group [Formula: see text] into a [Formula: see text]-Banach space.

On generalized hyperstability of a general linear equation [PDF]

open access: possibleActa Mathematica Hungarica, 2016
Let \({{\mathbb F}}\), \({{\mathbb K}}\) be two fields of real or complex numbers and X, Y be two normed spaces over \({{\mathbb F}}\), \({{\mathbb K}}\), respectively. In this paper, we use a modification of Brzdek’s method in [11] to obtain generalized hyperstability results for a general linear equation of the form $$g(ax + by) = Ag(x) + Bg(y),$$

Engineering ancestral protein hyperstability

Biochemical Journal, 2016
Many experimental analyses and proposed scenarios support that ancient life was thermophilic. In congruence with this hypothesis, proteins encoded by reconstructed sequences corresponding to ancient phylogenetic nodes often display very high stability.

Hyperstability and average hyperstability conditions for a broad class of gaussian stochastic systems

Information Sciences, 1979
Abstract The author investigates the hyperstability problem for a broad class of single-control stochastic systems which may be considered as disturbed models of given deterministic systems. The stochasticity comes from the control, which is disturbed by an additive Gaussian noise with its own gain.

In Vitro Evolution of a Hyperstable Gβ1 Variant

Journal of Molecular Biology, 2006
An in-vitro selection strategy was used to obtain strongly stabilized variants of the beta1 domain of protein G (Gbeta1). In a two-step approach, first candidate positions with a high potential for stabilization were identified in Gbeta1 libraries that were created by error-prone PCR, and then, after randomization of these positions by saturation ...

Hyperstability and identification

1970 IEEE Symposium on Adaptive Processes (9th) Decision and Control, 1970
This paper considers the process identification by means an adjustable model. An approach to the synthesis of this type of on-line identification system via the hyperstability theory is proposed. Two typical situations for identification are considered (the "ideal case" and the "real case").

Hyperstability of the Jensen functional equation

Acta Mathematica Hungarica, 2013
We present some observations on hyperstability for the Jensen equation on restricted domain. Namely, we show, under some weak natural assumptions, that functions satisfying the equation approximately (in some sense) must be actually solutions to it.

Hyperstability and adaptive filtering

IEEE Transactions on Acoustics, Speech, and Signal Processing, 1981
Recently, results from the area of system identification concerning the concept of system hyperstability have been applied to the analysis of adaptive filtering configurations. In particular, this analysis tool has allowed the development of a family of convergent adaptive recursive digital filtering algorithms, where the use of conventional gradient ...
