The Profile Hidden Markov Model (PHMM) can be poor at capturing dependency between observations because of the statistical assumptions it makes. To overcome this limitation, the dependency between residues in a multiple sequence alignment (MSA) which is the representative of a PHMM can be combined with the PHMM. Based on the fact that sequences appearing in the final MSA are written based on th...

Image encryption is essential to keep images secure either in personal devices or over the cloud drives. Various robust image cryptosystems have been implemented during past decades encrypted far from illegal decryption by eavesdroppers. Biological sequences contain high density information that introduce new challenges and opportunities traditional cryptography. This article presents a novel c...

In this article, we introduce PicXAA-Web, a web-based platform for accurate probabilistic alignment of multiple biological sequences. The core of PicXAA-Web consists of PicXAA, a multiple protein/DNA sequence alignment algorithm, and PicXAA-R, an extension of PicXAA for structural alignment of RNA sequences. Both PicXAA and PicXAA-R are probabilistic non-progressive alignment algorithms that ai...

Music similarity is a complex concept that manifests itself in areas such as Music Information Retrieval (MIR), musicological analysis and music cognition. Modelling the similarity of two music items is key for a number of music-related applications, such as cover song detection and query-by-humming. Typically, similarity models are based on intuition, heuristics or small-scale cognitive experi...

background and aims: rotaviruses are the main cause of gastroenteritis in the young of human and a variety of animals in the world. rotavirus g6 and g10 are the most prevalent genotypes in cattle worldwide, but are also found in human with possible origination from animals. materials and methods: in this work, we have detected the g6 and g10 genotypes of bovine rotaviruses isolated from diarrhe...

If you have just determined the sequence of an interesting bit of DNA, one of the first questions you are likely to ask yourself is “has anybody else seen anything like this before?” Fortunately, there has been a very successful international effort to collect all known sequences (both DNA and protein) into databases so that they can be searched. These databases (and searching tools) are freely...

Rotavirus G6 and G10 are the most prevalent genotypes in cattle worldwide, but are also found in human with possible origination from animals.

In this paper we show how, taking into account basic characteristics of biological vision, namely saccadic eye movements, a more effective image retrieval processing can be achieved. In particular, given two fixation sequences, extracted, respectively, from a target image and a test image, the sequences can be compared in order to provide a measure of similarity between the two images, and we p...

An unusual pattern in a nucleic acid or protein sequence or a region of strong similarity shared by two or more sequences may have biological significance. It is therefore desirable to know whether such a pattern can have arisen simply by chance. To identify interesting sequence patterns, appropriate scoring values can be assigned to the individual residues of a single sequence or to sets of re...
