Random aggregation models for the formation and evolution of coding and non-coding DNA

Provata, A. - In: Physica A: Statistical Mechanics and its Applications 264 (1999) 3, pp. 570-580

A random aggregation model with influx is proposed for the formation of the non-coding DNA regions via random co … correlations. For the formation of coding DNA a random closed aggregation model is proposed which predicts short range coding size … perturbations and which is characterised by well defined space and time scales, as observed in coding sequences. …

The Peace Scale: Conceptualizing and Operationalizing Non-Rivalry and Peace

Klein, James P.; Goertz, Gary; Diehl, Paul F. - In: Conflict Management and Peace Science 25 (2008) 1, pp. 67-80

Most efforts in international relations scholarship focus on understanding war and conflict. To the extent that peace is considered, it is often treated as an afterthought or a control condition. In this paper, we construct a five-level scale of dyadic peace. We then operationalize the scale...

An efficient layered data compression scheme with constraint analysis

Kamran, Muhammad; Shi, Feng; Xie, Yumin; Wang, Yizhuo - In: Mathematics and Computers in Simulation (MATCOM) 79 (2008) 4, pp. 1216-1232

Layered image transmission is successfully adopted for different system applications. Generally, in this technique, image is divided into number of layers for easy and fast transmission keeping the concept of multi-description representation. This configuration helps to make overall system...

FULL-RATE AND LOW-COMPLEXITY SPACE-TIME BLOCK CODING CONCATENATED WITH CHANNEL CODES

YU, XIANGBIN; BI, GUANGGUO - In: International Journal of Information Technology & … 06 (2007) 01, pp. 5-14

Space-time block (STB) coding has been an effective transmit diversity technique for combating fading recently. In this … paper, a full-rate and low-complexity STB coding scheme with complex orthogonal design for multiple antennas is proposed …, and turbo code is employed as channel coding to improve the proposed code scheme performance further. Compared with full …

Scaling properties of coding and non-coding DNA sequences

Provata, A.; Almirantis, Y. - In: Physica A: Statistical Mechanics and its Applications 247 (1997) 1, pp. 482-496

We study the size distribution of purine and pyrimidine clusters in coding and non-coding DNA sequences. We observe … that the cluster-size distribution P(s) follows an exponential decay in coding sequences whereas it follows a power …-law decay in non-coding sequences: P(s) ∼ s−1−μ, with a power exponent μ = 1.5–1.8. The mean-square displacement σ2(m) is …
