National Seminar on Probability and Statistics and Interdisciplinary Seminar on Biomathematics and Scientific Computing A joint session dedicated to the Year of Mathematical Biology will be held on  December 4, 2018 (Tuesday) at 3 p.m. in the Conference Room of IMI-BAS. A talk will be delivered by Prof. Nikolay Yanev on: Stochastic Models of Cell Proliferation Abtract: This is a survey lecture about stochastic modeling in cell proliferation kinetics. One purpose of this work is to present also some new ideas and problems in the theory of branching stochastic processes which appear as a result of cell proliferation modeling. Recall that the terminology "branching processes" was first introduced by Kolmogorov (1946) as well as the modern base of this theory. The following topics are considered: Some [...]

The next meeting of the National Seminar on Probability and Statistics will be held on  November 21, 2018 (Wednesday) at 2 p.m. in Room 403 of IMI-BAS. A talk will be delivered by Mariia Beliaeva on: Mathematics in carcinogenesis: mistakes and their consequences Abtract: With the arrival of evidence-based medicine mathematics is becoming closer to medical research, making the latter’s findings more science-based. However, some physicians develop mathematical models on their own, without any mathematical assistance and expertise. Sometimes the well-known conclusions of those amateurish theories mean nothing as they contain elementary mathematical mistakes, which nobody detects and corrects. The report describes the difference between mathematics and mathematics made by medics, in the carcinogenesis research. Epidemiological data analysis carried out by means of a special [...]

The next meeting of the National Seminar on Probability and Statistics will be held on  October 24, 2018 (Wednesday) at 2 p.m. in Room 403 of IMI-BAS. A talk will be delivered by Nikolay I. Ivanov (IMI - BAS) on: Asymptotic properties of Lee distance Abtract: Distances on permutations are often convenient tools for analyzing and modeling rank data. They capture the main feature of the data and provide a basis for further investigation. In this talk, some statistical properties of the Lee distance are studied. Asymptotic results for the random variable induced by Lee distance are derived and used to compare the Distance-based probability model and the Marginals model for complete rankings. Some statistical tools for estimating the unknown parameters and testing the [...]
