We investigate the typical cycle lengths, the total number of cycles, and the number of finite cycles in random permutations whose probability involves cycle weights. Typical cycle lengths and total number of cycles depend strongly on the parameters, while the distributions of finite cycles are usually independent Poisson random variables. © 2012 Wiley Periodicals, Inc.

Prediction of protein structural classes is of great significance to better understand protein folding patterns. An array of methods has been proposed to predict these structures based on sequences. However, the accuracy is strongly affected by the homology of sequences. In the present study, the features based on correlation coefficient of sequence and amino acid composition are extracted. Fle...

We use two co-evolving neural networks to determine new classes of protein secondary structure which are significantly more predictable from local amino sequence than the conventional secondary structure classification. Accurate prediction of the conventional secondary structure classes: alpha helix, beta strand, and coil, from primary sequence has long been an important problem in computationa...

Prediction of protein classification is an important topic in molecular biology. This is because it is able to not only provide useful information from the viewpoint of structure itself, but also greatly stimulate the characterization of many other features of proteins that may be closely correlated with their biological functions. In this paper, the LogitBoost, one of the boosting algorithms d...

a crd experiment was conducted to study three different soybean meals on experimental qualitative properties, digestibility of protein and performance in broiler chickens for a 42 day period. a total of 195 day-old ross 308 male broiler chickens were randomly distributed to 3 dietary treatments with five replicates of 13 chicks each. to measure digestibility of protein, thirty 15-day-old ross 3...

Interoperability is one of the major themes of research and development in information technology for the architecture, engineering, construction, and facilities management industries. A model-based approach to interoperability requires information structures that are standardized throughout the industry. The Industry Foundation Classes have been developed to provide this data exchange standard...

The paper presents a new 3D semantic building model dedicated to urban development. It provides the following special semantic features: storeys, passages, opening objects, and building variants, modelling different levels of detail and design respectively temporal variants. The model also includes a parametric part supporting easy generation of buildings and building variants in the urban desi...

In this study we examined the effectiveness of a computerbased geometry learning tool with 4 grade students. In both an experimental and control condition children constructed a series of common four-sided figures to fit a set of visual constraints. Additionally, children in the experimental condition were required to validate the presence of parallel segments, congruent segments, or right angl...
