SUMMARY ConFind (conserved region finder) identifies regions of conservation in multiple sequence alignments that can serve as diagnostic targets. Designed to work with a large number of closely related, highly variable sequences, ConFind provides robust handling of alignments containing partial sequences and ambiguous characters. Conserved regions are defined in terms of minimum region length,...

The problem of finding an appropriate geometrical/physical index for measuring a degree of inhomogeneity for a given space-time manifold is posed. Interrelations with the problem of understanding the gravitational/informational entropy are pointed out. An approach based on the notion of approximate symmetry is proposed. A number of related results on definitions of approximate symmetries known ...

The problem of estimating the power consumption at logic and register transfer levels is addressed from an information theoretical point of view. It is shown that the average switching activity can be predicted without simulation using either entropy or informational energy averages. Consequently, two new measures relying on these concepts are developed. The accuracy of these models is investig...

The paper presents a new approach to restoration characteristics randomized models under small amounts of input and output data. This approach proceeds from involving randomized static and dynamic models and estimating the probabilistic characteristics of their parameters. We consider static and dynamic models described by Volterra polynomials. The procedures of robust parametric and non-parame...

“Residual” entropy (3–12 J mol 1 K 1) is present near 0 K in some crystals composed of nonsymmetric molecules, for example, CO, N2O, FClO3, and H2O. It is detected only by the difference between spectroscopic calculations of the absolute entropy of the gaseous chemical and calorimetric measurements of its heat capacity (and phase changes) from 0 K to the temperature of the gas. Calorimetry, lik...

This paper addresses aesthetic problem in cellular automata, taking a quantitative approach for aesthetic evaluation. Although the Shannon’s entropy is dominant in computational methods of aesthetics, it fails to discriminate accurately structurally different patterns in two-dimensions. We have adapted an informational measure to overcome the shortcomings of entropic measure by using informatio...

Measurements of graphs and retrieving structural information complex networks using degree-based network entropy have become an informational theoretical concept. This terminology is extended by the concept Shannon entropy. In this paper, we introduce with having edge weights which are basically redefined Zagreb indices. Some bounds calculated to idealize performance in limiting different kinds...

Animals and humans engage in an enormous variety of behaviors which are orchestrated through a complex interaction of physical and informational processes: the physical interaction of the bodies with the environment is intimately coupled with informational processes in the animal’s brain. A crucial step toward the mastery of all these behaviors seems to be to understand the flows of information...

An alternate evolutionary hypothesis is discussed: non-equilibrium thermodynamics. It is argued that evolution is an axiomatic consequence of organismic information obeying the second law of thermodynamics and is only secondarily connected to natural selection. As entropy increases, the information within a biological system becomes more complex or variable. This informational complexity is sha...

With the rapid development of Deep Neural Networks (DNNs), various network models that show strong computing power and impressive expressive power are proposed. However, there is no comprehensive informational interpretation of DNNs from the perspective of information theory. Due to the nonlinear function and the uncertain number of layers and neural units used in the DNNs, the network structur...
