This paper proposes a new probabilistic non-extensive entropy feature for texture characterization, based on a Gaussian information measure. The highlights of the new entropy are that it is bounded by finite limits and that it is non additive in nature. The non additive property of the proposed entropy makes it useful for the representation of information content in the non-extensive systems co...

We construct a four-dimensional BPS saturated heterotic string solution from the Taub-NUT solution. It is a non-extremal black hole solution since its Euler number is non-zero. We evaluate its black hole entropy semiclassically. We discuss the relation between the black hole entropy and the degeneracy of string states. The entropy of our string solution can be understood as the microscopic entr...

By combining the explicit formula of the Shannon informational entropy ) , ( Y X H for two random variables X and Y , with the entropy )) ( ( X f H of ) (X f where (.) f is a real-valued differentiable function, we have shown that the density of the amount of information in Shannon sense involved in a non-random differentiable function is defined by the logarithm of the absolute value of its de...

Paederus (Harpopaederus) xui Peng & Li, sp. n. (Sichuan: Micang Shan) is described. Additional records of five Harpaederus species are reported. All of these species are illustrated.

To the Editor In an article entitled “Prognostic Significance of CXCL12 Expression in Patients With Colorectal Carcinoma,”1 we found that the authors may have inadvertently annotated CAM5.2 as cytokeratins (CKs) 8 and 18 by using a pair of square brackets to reference some reports, which might suggest that CAM5.2 is identical to CK8 and CK18. Becton Dickinson (BD) Biosciences revised the data s...

In this study, convection flow in microchannel heat sink with offset fan-shaped reentrant cavities in sidewall filled with Fe3O4-water is numerically investigated. The effects of changing some parameters such as Reynolds number and magnetic field are considered. The nanofluid flow is laminar, steady and incompressible, while the thermo-physical properties of nanoparticles were assumed constant....

The low density parity check codes whose performance is closest to the Shan-non limit arèGallager codes' based on irregular graphs. We compare alternative methods for constructing these graphs and present two results. First, we nd a `super{Poisson' construction which gives a small improvement in empirical performance over a random construction. Second, whereas Gallager codes normally take N 2 t...

An extension of the standard Shan-Chen model for non ideal-fluids, catering for mid-range, soft-core and hard-core repulsion, is investigated. It is shown that the inclusion of such mid-range interactions does not yield any visible enhancement of the density jump across the dense and light phases. Such an enhancement can however be obtained by tuning the exponents of the effective interaction. ...
