Stars do not simply pop up on the main sequence. Before stars arrive zero-age sequence, they form in collapses of molecular clouds, gain matter through accretion processes, and compress their cores until hydrogen can burn full equilibrium. Although this evolutionary phase lasts a relatively short time, it is imprint these important physical processes that often ignored by simplified assumptions...

The absolute indicator is one of the measures used to determine the resistance offered by a Boolean function when used in the design of a symmetric cryptosystem. It was proposed along with the sum of square indicator to evaluate the quality of the diffusion property of block ciphers and hash functions. While the behaviour of the sum of square of random Boolean functions was already known, what ...

– We study analytically the behavior of the largest Lyapunov exponent λ1 for a onedimensional chain of coupled nonlinear oscillators, by combining the transfer integral method and a Riemannian geometry approach. We apply the results to a simple model, proposed for the DNA denaturation, which emphasizes a first order-like or second order phase transition depending on the ratio of two length scal...

For the commercialization of GM food crops the biosafety issues pertaining to their allergenicity need to be thoroughly investigated. Sequence homology with the known allergens can serve as possible indicator of allergenicity since sequence homology between the proteins has high probability of causing crossreactions. However, structures with low sequence similarity may also cause cross-reactivi...

Ascertaining epidemic phase for a sexually transmitted disease (STD) has depended on secular trend data which often contain significant artefacts. The usefulness of sexual network structure as an indicator of STD epidemic phase is explored in an analysis of community wide genital chlamydia reports, with network analysis of interviewed cases and linked sexual partners, in Colorado Springs, USA, ...

Current methods to evaluate the severity and progression of the disease, effectiveness of therapy and survival among cancer patients are generally limited in their prognostic ability. Whole-body phase angle, measured by using a tetrapolar, phase-sensitive bioelectrical impedance analyzer, offers a new approach. Phase angle (arc tangent of the ratio of reactance to resistance) is a non-invasive ...

This paper reports a novel symbol-to-signal mapping for DNA sequences, based on the concept of categorical periodograms. A categorical periodogram is a numeric sequence with the n-th element of the sequence indicating the number of occurrences of cycles with period n in it. The period of the cycle is defined as the number of intervening events plus one. Spectral analysis studies have been condu...
