Marcin Penconek (Międzydziedzinowa Szkoła Doktorska UW)
Decision-Making Computations in Neuronal Networks (Modelowanie podejmowania decyzji w sieciach neuronowych)
Recent advances in neuroscience provide a new perspective on how categorical decisions are computed in the brain and how the choice circuits performing such computations are organized. This knowledge was instrumental in developing the mechanistic …

Destabilization of a population model due to a seasonally varying Allee effect impacting seasonal synchronization
Extreme weather conditions due to climate change lead to seasonal variations in species’ life cycles. It can impact the distribution and abundance of populations by influencing their habitats and food sources, leading to changes in …

Modeling the effects of human behavior on respiratory viruses coinfection dynamics
Respiratory virus coinfection refers to the simultaneous infection of two viruses spreading in the respiratory tract of the same host. This phenomenon can involve coronaviruses, respiratory syncytial virus, human rhinoviruses, adenoviruses, or influenza viruses. Based …

Jan Wróblewski (MIM UW)
Convergence of a cellular automata reaction-diffusion model to the PDE model
Cellular automata (CA) are used to simulate physical processes with various degrees of precision, but the theoretical quantitative bounds for this precision are rarely computed. We create a stochastic CA model of reaction-diffusion process with …
Jan. 17, 2024, 2:15 p.m.
Ana Marco-Salamero (student in the Erasmus program)
Techniques for the evolution of random graphs models; key applications and future directions.
With the idea of modeling the behaviour of social networks over time, here are shown some preliminary results on random graph evolution using techniques inspired by quantum mechanics. After some formalisms, the idea is showing …

Mateusz Dębowski (doktorant MIM)
Pewne aspekty mechanizmów molekularnych cyklu komórkowego i wzrost diauksyczny w ujęciu matematycznym
Podczas seminarium opowiem o swoim doktoracie. Zaprezentuję najważniejsze wyniki, omówię pokrótce artykuły, które w rozprawie zostały opisane i rozszerzone. Ponadto przedstawię możliwe dalsze perspektywy oraz uwagi recenzentów, do których się odniosę.

Javad Mohamadichamgavi (MIM UW)
The Impact of Time Delay on Mutant Fixation in Evolutionary Games
Evolutionary game theory examines how strategies spread and endure in populations through reproduction and imitation based on their evolutionary fitness. Traditional models assume instantaneous population dynamics where the current population state solely determines fitness. However, …

Krzysztof Argasiński (MIM UW)
Impact of maturation delays on the eco-evolutionary dynamics of Hawk-Dove game
In the talk the eco-evolutionary dynamics of the demographic version (expressed in expliciit mortality and fertility payoffs) of Hawk-Dove game will be analyzed. We will show that the trajectories are attracted by so called subnullcines …

Agnieszka Bartłomiejczyk (Politechnika Gdańska)
Existence of wave solutions of a glioma model in a porous medium
We study the glioma model with continuous chemotherapy administered to tumours evolving not only due to proliferation, but also due to the diffusion process. We consider model with non-linear diffusion describing motility in a porous …

Sanacja i Wehrmacht
Spróbuję matematycznie porównać armię polską i Wehrmacht w 1939 roku. Opiszę stosowanie równań różniczkowych Lanchestera na armiach ludzi i mrówek w celu określenia efektywności taktycznej w starciu. Potem przejdę do moich prób modelowania zmian w …

Agnieszka Wiszniewska-Matyszkiel (MIM UW)
How responsive should a firm be to customers expectations?
[Economic abstract from the published paper] This study explores ways to optimally align quality with customer expectations in light of changes in expectations related to experience with the actual quality of the product. A firm’s …

Marcin Choiński (SGGW)
A Discrete SIS Model of Epidemic for Heterogeneous Population without Discretization of its Continuous Counterpart
We propose a model of an infectious disease transmission in a heterogeneous population consisting of two different subpopulations: individuals with low and high susceptibility to an infection. This is a discrete model which was built …

Stability of periodic solution in a model of CAR-T cell immunotherapy - continuation
This seminar is a continuation of the presentation from two weeks ago.

Burcu Gürbüz (Institute of Mathematics, Johannes Gutenberg-University Mainz)
Analysis of a model of the Calvin cycle
The dynamical properties of systems of ordinary differential equations (ODEs) have been studied in various chemical reaction network formulations. Among these, the Calvin cycle stands out as a widely recognised chemical reaction network that plays …

Stability of periodic solution in a model of CAR-T cell immunotherapy
I will talk about a model of CAR-T (Chimeric Antigen Receptor T) cell therapy that was presented in paper O. León-Triana et al.. (Cancers, 2021). I consider an system of 4 ODEs with impulses and …
