MOTIVATION Identifying the set of genes differentially expressed along time is an important task in two-sample time course experiments. Furthermore, estimating at which time periods the differential expression is present can provide additional insight into temporal gene functions. The current differential detection methods are designed to detect difference(More)
We present progress on a comprehensive, modular, interactive modeling environment centered on overall regulation of blood pressure and body fluid homeostasis. We call the project SAPHIR, for "a Systems Approach for PHysiological Integration of Renal, cardiac, and respiratory functions". The project uses state-of-the-art multi-scale simulation methods. The(More)
This paper presents a new growing neural network for sequence clustering and classification. This network is a self organizing map (SOM), which has the properties of stability and plasticity. The stability concerns the preservation of previously learned knowledge and the plasticity concerns the adaptation to any change in the input environment. These(More)
This work presents approaches for sequence clustering and classification. These approaches use the self organizing map "SOM". The inputs of the map are modelled in order to take into account the information and the correlation of the patterns contained in the sequences. The first approaches represent the input of the map by a representative vector or by a(More)
MOTIVATION Piwi-interacting RNA (piRNA) is the most recently discovered and the least investigated class of Argonaute/Piwi protein-interacting small non-coding RNAs. The piRNAs are mostly known to be involved in protecting the genome from invasive transposable elements. But recent discoveries suggest their involvement in the pathophysiology of diseases,(More)
On behalf of the organizing committee, It gives me great pleasure to extend a warm welcome to all participants of the Eighth International Symposium on Signal Processing and Its Applications (ISSPA 2005). ISSPA was initiated in 1985 to promote signal processing research in the Asia-Pacific region and to strengthen research collaboration between Asia-Pacific(More)
