Automated Mapping using Multilevel B-Splines'
Applied GIS. 2005.; Monash University ePress: Victoria, Australia.
This paper describes application of
multilevel B-Splines approximation (MBA) algorithm to the SIC2004
exercise as a high performance automatic mapping means in emergency
situations. MBA method was compared with kriging, and various
flexible MBA method’s tuning “controls” were proposed and discussed.
Outliers automatic detection and delineation techniques considered
could be used to process outliers without the loss in performance.
Prior data were used to adjust method parameters and discover the
pattern of spatial correlation. The interpolation algorithm
development did not assume any information about the phenomena in
addition to values given.

Hierarchical Multispectral Image Classification Based on Self Organized Maps
IGARSS’99 IEEE 1999. International Geoscience and Remote Sensing Symposium, Hamburg, Germany, 1999, p.2510-2512.
One of the problems in the thematic interpretation of the remote sensor (RS) data is the processing of the sets of multispectral, multydate images. The problem is that when we try to compare two and more RS image, we have to rectify their geometry and correct atmospheric effects. While the geometric correction could be done with any precision, the atmospheric correction for a set of images is a very complex task, and it could not be solved in a common case. We propose a new approach, based on the artificial neural networks, for a stable RS images classification and interpretation without the atmospheric correction. That approach, using the Kohonen’s Self Organized Maps (SOM) , has been realized as a part of the ScanEx image processing technology in a computer program NeRIS (Neural Raster Interpretation System). The Sammon’s mapping  of that SOM classification from the p dimensional input image space to the 2 dimensional points on a plane (whereby the distances between the mapped vectors tend to approximate to distances of the input vectors), was used for hierarchical classification and stable thematic interpretation of the RS images.

Mixed effects models and extensions in
ecology with R
ISSN 1431-8776, ISBN 978-0-387-87457-9, Library of Congress No:
Building on the successful Analysing
Ecological Data (2007) by Zuur, Ieno and Smith, the authors now
provide an expanded introduction to using regression and its
extensions in analysing ecological data. As with the earlier book,
real data sets from postgraduate ecological studies or research
projects are used throughout. The first part of the book is a
largely non-mathematical introduction to linear mixed effects
modelling, GLM and GAM, zero inflated models, GEE, GLMM and GAMM.
The second part provides ten case studies that range from koalas to
deep sea research. These chapters provide an invaluable insight into
analysing complex ecological datasets, including comparisons of
different approaches to the same problem. By matching ecological
questions and data structure to a case study, these chapters provide
an excellent starting point to analysing your own data. Data and R
code from all chapters are available from

GeneNet: a database for gene networks and its automated visualization.
MOTIVATION: Gene networks that provide the regulation of physiological processes are the basic feature of organisms. Information regarding the regulation of gene expression and signal transduction pathways is increasing rapidly. However, the information is hard to formalize and systematize. Ways and means for automated visualization of the gene networks based on their formalized description are needed.
RESULTS: The object-oriented database GeneNet and the software for its automated visualization have been developed. The main principles of a formalized description of the gene network have been worked out. Antiviral response and erythropoiesis are provided as examples to show how this is achieved. The GeneNet graphical user interface written in Java provides automated generation of the gene network diagrams and allows visualization and exploration of the GeneNet database through the Internet. A system of filters allows the selection of particular components of the network for visualization.

Gene Networks: a database and its automated visualization through the internet in the genenet computing system.
Proc. Int. Conf. Bioinf. of Genome Regulation and Structure (BGRS'98). 1998;1:82-85.
Abstract: Gene networks provide the regulation of physiological processes in eukaryotic organisms. Ways and means for automated visualization of the gene networks based on their formalized description are needed. Rapidly increasing information regarding the regulation of gene expression and signal transduction pathways is hard to formalize and systematize. The main principles of a formalized description of various regulatory processes have been worked out for the GeneNet computer system designed for accumulation of the data on gene networks and their visualization through the Internet. The GeneNet system is bipartite and includes: (1) a database containing information on gene networks and (2) a Java program for automated construction of the gene network diagrams based on their formalized description in the database. The GeneNet graphical user interface allows visualization and exploration of the GeneNet database through the Internet.
The GeneNet is a part of GeneExpress - a system for analysis of genomic regulatory sequences (http://wwwmgs.bionet.nsc.ru/systems/GeneExpress/ >>) , developed in the Institute of Cytology and Genetics, Siberian Branch of the Russian Academy of Sciences. GeneNet is available at http://wwwmgs.bionet.nsc.ru/systems/MGL/GeneNet/ >>

High heterogeneity of higher eukaryotic gene promoters, transcribed by RNA polymerase II.
Dokl Akad Nauk. 1997;375(5):693-995. Russian.
Abstract: The degree of similarity between higher eukarotic promoter sequences transcribed by RNA-polymerase II was to be estimated depending on the species or tissue-specific expression of the corresponding genes. Samples of promoter fragments ([-190; +20] region relative to the transcription start was divided into 7 fragments of 30 bp in length each) have been analyzed for homo sapiens, bos taurus, mus musculus, rat norvegicus, gallus gallus, xenopus laevis and drosophila melanogaster. The sequences were extracted from the EMBL data library, tissue specificity data from the EPD. The similarity between the sequences of the i-th fragments of two promoters (i=1,..7) was assumed non-random if a higher alignment score was obtained for them using the program FASTA than for random sequences with the same oligonucleotide content in 95% of cases. The measure of similarity for the group as a whole was the ratio of the number of non-randomly similar pairs of sequences to the total number of all possible pairs in the group. As turned out, the degree of similarity for the promoters of a species just insignificantly exceeded the random threshold, the highest similarity being observed in the TATA-box and its vicinity. As to the tissue-specific promoters, it was typical of them to have on the whole higher degrees of similarity within a species. That the promoters of non-homologous genes contain non-randomly similar fragments uncovers an important role of convergence in the evolution of promoters. [PMID: 9493004]

Computer analysis and recognition of the transcription regulatory elements in eukaryotic genomes.
Proc. German Conf. on Bioinformatics (GSB'96). 1996; p..
Abstract: A feature of transcription regulatory regions of eukaryotic genes is a clear-cut hierarchy and modular structure (Kel, at al., 1995a). Binding sites for individual transcription factors are at the bottom. Composite elements are at the intermediate level; these are composed of closely located (adjacent or even overlapping) transcription factor binding sites that function as one by virtue of intensive protein-protein interaction between the transcription factors. At the highest level are promoters and enhancers. On the background of the projects for total sequence of the human, mouse, Drosophila and other eukaryotic genome, computer analysis and identification of transcription regulatory units is an extremely important problem. We report results of computer analysis and identification of transcription factor binding sites, composite elements, promoters.

Rapid estimates of statistical significance of the pairwise nucleotide sequence alignment.
Proc. Int. Conf. Bioinf. of Genome Regulation and Structure (BGRS'98). 1998;2:301-304.
Abstract: Statistical significance of the similarity observed is the main question while comparing sequences. This problem has not yet been solved mathematically for optimal aligning of the sequences containing insertions and deletions. We have carried out the regression analysis of the observed similarity of random sequences depending on their length and nucleotide composition and are proposing a practical method to estimate the probability of the similarity observed to be statistically significant. The regression parameters being determined for a given alignment scheme (similarity matrix and penalties for deletions) for a pair of nucleotide sequences, the statistical significance of the similarity observed can be precisely estimated basing on only their lengths and nucleotide composition.

New method for the study of the modular structure of transcription regulatory regions.
Proc. Int. Conf. Bioinf. of Genome Regulation and Structure (BGRS'98). 1998;2:430-433.
Abstract: It is known that transcription regulatory regions have a modular structure and contain transcription factor binding sites, composite elements, enhancers, silencers, and other functional modules. The situation when the same functional module is located in different positions relative to the transcription start. We propose to solve this problem by combining the methods of pairwise and multiple alignment with analysis of the similarity profiles of the sequences. The promoters of interferon-induced and erythroid-specific genes were investigated. Analysis of similarity profiles for this group promoters reveals that their have large number of similar motifs. The motifs revealed on promoters of interferon-induced genes were subjected to multiple alignment using Gibbs algorithm and was shown their correspondence to binding sites of transcription factor regulating antiviral response.

Structural and compositional features of 5' untranslated regions of higher plant mRNAs.
Proc. Int. Conf. Bioinf. of Genome Regulation and Structure (BGRS'98). 1998;1:210-213.
Abstract: Computer analysis of the 5'untranslated regions (5'UTRs) of plant mRNA sequences is reported. In comparison with 3'UTRs, the nucleotide composition of 5'UTRs is characterized by a considerable asymmetry in the content of the complementary nucleotides (G/C and A/U) and a strong decrease in the frequency of AUG triplet. It has been also shown that mRNA 5'UTRs of dicot and monocot genes differ in a number of characteristics (length, nucleotide content, and context of translational start codon). Statistically, leaders of dicot mRNAs are A+U-rich sequences, and most of them (77%) vary in length between 11 and 120 nt; whereas 5'UTRs of monocot mRNAs are C-rich, and their lengths are mainly distributed between 40 and 120 nt (68% in analyzed sample). Consensus sequences of translational start contexts are aaaaaaaaaAaaAUGGCu for the dicot and ggggcggccA/GCcAUGGCG for the monocot mRNAs. AUG codon contexts in monocot mRNAs appeared to be considerably different from those in dicots by the occurrence of certain combinations of nucleotides in -3 and +4 positions around AUG. The doublet G-3/G+4 was found to be the most frequent combination in monocot mRNAs (35.3%), whereas the doublet A-3/G+4 was the most frequent in dicot mRNAs (35.9%).

The MGL computer system--an instrument for generating, graphically representing, and analyzing regulatory genomic sequences.
Mol Biol (Mosk). 1997;4(31):647-655. Russian.
Abstract: A computer system MGL (Molecular Genetic Language) was designed for search, extraction from databases, sample generation, visualization, and analysis of regulatory genomic sequences (RGS): regions of DNA/RNA sequences involved in regulation of various molecular genetic processes: replication, transcription, splicing, translation, etc. The MGL system offers a wide range of possibilities for searching and extracting the information on RGS from the EMBL, TRANSFAC, TRRD, Compel, EPD, and Nucleo databases. MGL generates samples of promoters, transcription factor binding sites, and nucleosome positioning sites in an automatic mode using the EMBL database as a source of nucleotide sequences, while the data on RGS location in the sequences are extracted from the EPD, TRRD, and Nucleo databases, respectively. The MGL system also generates automatically nucleotide sequence samples of various RGS (promoters, splicing sites, mRNA, CDS, 5'- and 3'-untranslated regions, polyadenylation sites) basing on semantic analysis of the EMBL FEATURE TABLE information. The MGL system provides visualization of data on the RGS location in nucleotide sequences from TRRD and EMBL databases as well as from results of transcription factor binding sites search in a map form. The MGL system is provided with specialized script language allowing a user to carry out sample generation and analysis of RGS in automatic mode. The MGL system has a user friendly interface designed for Windows3.x and Windows 95. [PMID: 9340492]
