Paweł Zwoleński (IM PAN)
Phenotypic evolution of hermaphrodites
We consider finite, phenotype-structured population of hermaphrodites, and build an individual based model which describes interactions between the individuals. The model contains such elements as mating of individuals (random or assortative), inheritance of phenotypic traits …

Beata Zduniak (SGGW Warszawa)
A VENTRICULAR TACHYCARDIA AND AV NODAL DOUBLE RESPONSE TACHYCARDIA IN A MODIFIED VAN DER POL EQUATION
A modified van der Pol equation is a mathematical model used to recreate physiological behaviour in the conducting heart's system. The use of certain values for coupled terms allows to simulate circulating re-entry waves, which …

Global stability for some types of delayed logistic equations - continuation
This time we will focus on the main goal that is the study of simple epidemic model of vector-borne diseases proposed by Cooke which belong to the class of delayed logistic equations.

Urszula Foryś (Uniwersytet Warszawski)
Global stability for some types of delayed logistic equations
We will focus on proving global stability for three different types of delayed logistic equation. Our main goal will be to study simple epidemic model of vector-borne diseases proposed by Cooke which belong to the …

Marek Bodnar (Uniwersytet Warszawski)
Global stability of steady steady state of delay differential equations in neural network model
We prove that a strong attractor of a discrete map implies global stability of a corresponding system of delay differential equations. We apply this result to a delayed Hopfield's model. We prove also that every …
Oct. 23, 2013, 2:15 p.m.
Magdalena Bogdańska (Uniwersytet Warszawski)
Delay effects in the response of low grade gliomas to radiotherapy: a mathematical model and its therapeutical implications
Low grade gliomas (LGGs) are a group of primary brain tumors, which are highly inﬁltrative and generally incurable but have median survival time of more than 5 years because of low proliferation. Management of LGGs …
Oct. 16, 2013, 2:15 p.m.
Simon Angus ((Monash University) )
he Similarity of Human Interest Amongst the Nations
Abstract: Are Australians more like Americans, British, New Zealanders or Indonesians? What shapes human interests more: contemporary events or events from long ago? This talk aims to answer these questions with a novel data source …
Oct. 9, 2013, 2:15 p.m.
Simon Angus (Monash University)
"Challenges in silico: modelling delays, death and repair in EMT6/Ro tumor cells under a variety of multi-dose irradiation protocols"
Abstract: In silico (computational) techniques offer the potential to investigate efficiently many aspects of tumour development and progression. In particular, a calibrated, dynamic, in silico tumour model could be used to probe the combinatorially extensive, …
June 5, 2013, 4:15 p.m.
Marek Bodnar (Uniwersytet Warszawski)
Traveling waves in reaction-diffusion equations with time delay
I will talk about traveling waves in reaction diffusion systems with delay. On the basis on some simple equation I will show problems that arise when looking for traveling fronts in equation with delay. In …
May 15, 2013, 4:15 p.m.
Prof. Urszula Ledzewicz (USA)
Timing and Dosage of Anti-Cancer Drug Therapies: An Optimal Control Approach
A systematic study of cancer treatment requires that we take into account not only the cancerous cells and their growth, but also various aspects of the tumor microenvironment. Its elemets include various types of cancer …
May 8, 2013, 4:15 p.m.
Marzena Dołbniak (Gliwice)
Protocols of anti-angiogenic and combined anticancer therapy
In brief introduction information about negative results obtained after single anti-angiogenic treatment and reasons for use anti-angiogenic factors to normalization of chaotic and unregulated tumor vessels are presented. I discussed several simple ordinary differential equation …
April 24, 2013, 4:15 p.m.
Łukasz Płociniczak (Politechnika Wrocławska)
A New Mathematical Model of Corneal Topography
Sight is the most important sense that we posses. It is crucial to understand the mechanics of vision in order to treat various diseases that may occur and disturb regular seeing. The eye's main part …

Urszula Foryś (Uniwersytet Warszawski)
News from IMBM: modelling of prostate cancer immunotherapy
Abstract: During my visit in IMBM in January I have discussed the idea of new project with the team of Prof. Zvia Agur. We have decided to focus on the modelling of prostate cancer immunotherapy. …
April 10, 2013, 4:15 p.m.
Michal Komorowski (IPPT Homing+)
The concept of information at the interface between statistics and systems biology
The purpose of the talk is to discuss intricacies of quantifying information in some problems arising at the interface between statistic and biology. Behaviour generated by interacting molecules, cells or tissues is not random but …
March 20, 2013, 4:15 p.m.
Andrea Quartarone (University of Messina, Italy) and Tatiana V. Ryabukha (MIMUW and NANU, Ukraine)
Stability of the solutions of the mesoscopic equation that corresponds to the replicator equation.
The replicator equation is a deterministic nonlinear equation arising in evolutionary game theory describing the evolving lifeforms in terms of frequencies of strategies. It is related to a mean field approach and therefore it has …
