Introduction The need to dispose of human-generated waste streams is growing in line with the expansion of urban population centers. This is particularly true for the byproducts of wastewater treatment. According to the US EPA, there are over 7 million dry tons of biosolids (stabilized sewage sludge) produced per year in the US. In 2004, 49% of biosolids were beneficially used—primarily for agr...

In this paper, a novel methodology called a reference model approach to stability analysis of neural networks is proposed. The core of the new approach is to study a neural network model with reference to other related models, so that different modeling approaches can be combinatively used and powerfully cross-fertilized. Focused on two representative neural network modeling approaches (the neu...

Secondary structure prediction methods are widely used bioinformatics algorithms providing initial insights about protein structure from sequence information. Significant efforts to improve the prediction accuracy over the past years were made, specially the incorporation of information from multiple sequence alignments. This motivated the search for the factors contributing for this improvemen...

Gene expression on prokaryotes initiates when the RNA-polymerase enzyme interacts with DNA regions called promoters, where are located the main regulatory elements of the transcription process. Despite the improvement of in vitro techniques for molecular biology analysis, characterizing and identifying promoters is a complex task. In silico approaches are used to recognize theses regions. Never...

We sequenced the complete mitochondrial control regions of 11 red knots (Calidris canutus). The control region is 1168 bp in length and is flanked by tRNA glutamate (glu) and the gene ND6 at its 5' end and tRNA phenylalanine (phe) and the gene 12S on its 3' end. The sequence possesses conserved sequence blocks F, E, D, C, CSB-1, and the bird similarity box (BSB), as expected for a mitochondrial...

One of the most important challenges for Bioinformatics is the simulation of a single cell, even if we restrict ourselves to simple models of the molecular networks responsible for the behavior of organisms. The challenge involves not only the development of experimental techniques to obtain kinetic parameters that characterize the myriad reactions occurring inside cells, but also computational...

Understanding biochemical pathways is one of the big challenges of the field of molecular biology nowadays. Computer science can contribute in this area in a variety of ways. One of them is providing formalisms and tools to simulate and check properties of pathways. One formalism that is well known and suited for modeling concurrent and distributed systems is Milner’s Calculus of Communicating ...

Vision scientists are increasingly relying on the point-light technique as a way to investigate the perception of human motion. Unfortunately, the lack of standardized stimulus sets has so far limited the use of this technique for studying social interaction. Here, we describe a new tool to study the interaction between two agents starting from point-light displays: the Communicative Interactio...
