Aleksandra Falkiewicz (Politechnika Łódzka, doktorantka)
Modeling of proliferation of gene mutations in aged structured populations
One of the basic methods in modeling the proliferation of gene mutations is by the systems of ordinary differential equations expressing appropriate conservation principles. Another possibility is to use a model containing more information about …

Mateusz Dębowski (doktorant MIM)
Cell cycle model - continuation
My presentation will be continuation about model of cell cycle which include influence of protein CDC6. In my first presentation I showed my primary approach with many unknown functions in model and now I will …

Oskar Górniewicz (doktorant w projekcie A. Wiszniewskiej-Matyszkiel)
Verification and refinement of Fischer-Mirman fish wars model
In 1992 the paper "Strategic Dynamic Interaction -- Fish wars" by Fischer and Mirman was published. In that paper authors described dynamic, discrete, two population fish model. It is considered three problems: 1) symbiosis 2) …

Jan Poleszczuk (H. Lee Moffitt Cancer Center & Research Institute)
Abscopal benefits of localized radiotherapy depend on activated T cell trafficking and distribution between metastatic lesions
It remains unclear how localized radiotherapy for cancer metastases can occasionally elicit a systemic antitumor effect, known as the abscopal effect, but historically it has been speculated to reflect the generation of a host immunotherapeutic …
Dec. 2, 2015, 2:15 p.m.
Roman Cherniha (Institute of Mathematics of NASU, Kyiv, Ukraine)
A simplified Keller-Segel model: construction of exact solutions for the Cauchy and Neumann problems
A simplified Keller-Segel model is studied by means of Lie symmetry based approaches. It is shown that this (1+2)-dimensional nonlinear system is invariant with respect infinity-dimensional Lie algebra. The result is extended on the Cauchy …
Nov. 25, 2015, 2:15 p.m.
Marcin Choiński (doktorant MIM)
Discrete models of epidemics
Two discrete models of epidemics will be presented. In the firstmodel there is assumption that there are two groups in the population – healthy and infected people. In the second model there is additional third …

Piotr Bajger (MISDoMP)
Mathematical models for the corrosion of magnesium and its alloys
Biodegradable materials have been extensively studied in recent years due to their potential to revolutionise the use of orthopaedic implants. In this context, one of the most promising candidates for a biomaterial is magnesium. When …
Nov. 4, 2015, 2:15 p.m.
Magdalena Bogdańska (Uniwersytet Warszawski)
A data-motivated density-dependent diffusion model of in vitro glioblastoma growth
I will present very recent article by Stepien, Rutter and Kuang in Mathematical Biosciences and Engeneering, 2015. The research concerns modelling glioblastoma multiforme, which is is an extremely fatal brain cancer. It is characterized by …

Vladimir Mityushev (Department of Computer Sciences and Computer Methods, Pedagogical University Krakow)
Pattern formations and optimal packing
Patterns of different symmetries may arise after solution to reaction-diffusion equations. Hexagonal arrays, layers and their perturbations are observed in different models after numerical solution to the corresponding initial-boundary value problems. We demonstrate an intimate …

Jan Karbowski
Optymalizacja połączeń w mózgu
Seminarium będzie poświęcone strukturze mózgu ssaków, w szczególności korze mózgowej (kluczowej dla procesów kognitywnych). W przeszłości wysuwane były sugestie, że struktura mózgu jest w dużej części konsekwencją ewolucyjnej minimalizacji uzwojeń neuronowych (dendryty i aksony), jako …

Mateusz Dębowski (Uniwersytet Warszawski)
A mathematical model for pancreatic cancer growth and treatments
I will present results of Y. Lauzoun, C. Xue, G. B. Lesinski and A. Friedman from 2014. They developed model of pancreatic cancer and shows that drugs aimed at suppressing cancer growth are effective only …

Yaroslav Bihun (Yuriy Fedkovych Chernivtsi National University, Department of Applied Mathematics and Information Technology)
Systems of Multifrequency Differential Equations with Delay and their Application in Mathematical Modelling of Immune Response in Infectious Diseases
The obtained results in this work are a further development for multifrequency systems with constant and linear delay results of A.M. Samoylenko and R.I. Petryshyn for ordinary differential equations. New theorems on the existence and …

Magdalena Bogdańska (Uniwersytet Warszawski)
Mathematical model of brain tumour with glia-neuron interactions and chemotherapy treatment
I will present recent results of Iarosz et al., who propose a mathematical model for the evolution of a brain tumour under the influence of chemotherapeutic agents. Model describes the interactions among glial cells, neurons …

Fale wapniowe generowane napływem wapnia do komórki z przestrzeni międzykomórkowej poprzez mechanicznie otwierane kanały jonowe
Obserwacje wskazują, ze tego typu fale są dość powszechne. Ponadto mają one prędkości o rząd większe niż zwykłe fale wapniowe podtrzymywane przez autokatalityczne wydzielanie wapnia z magazynów wapniowych. W wykładzie zaproponujemy matematyczny model takich fal …

Modelling gene expression of Hes1 protein
We analyze a model of gene transcription and protein synthesis and we investigate the effect of multiple binding sites in the Hes1 promoter. Hes1 protein, a transcriptional repressor, inhibits its own transcription by directly binding …
