Recent Developments in Neurotechnology
The idea of moving robotic devices just by thinking, through use of brain-computer interfaces (BCIs), has been research area that attracted attention since 1970s. BCI systems are used to allow users to communicate with computers …

Discrete-time SIS models
I will talk about discrete-time SIS models which were based on their continuous counterparts. The first type of models reflects the dynamics of epidemics in a homogeneous population - in this case two-dimensional systems are …

Structure and vulnerability of weighted empirical food webs
Species extinctions are compromising ecosystem functioning and services around the globe. The effects of species loss propagate over food webs (trophic networks). Food webs are directed graphs that represent feeding relationships, encoding matter flows as …

A semigroup approach to hyperbolic systems on networks
Partial differential equations are not only purely mathematical objects but often they describe some natural phenomena. Given an equation we need to solve three basic problems. The first one is to choose an appropriate method …

Revision of diffusion on metric graph
Dynamical processes along the edges of a graph with appropriate transmission conditions in the vertices appeared first around 1980. In the last forty years variety of new tools from analysis has been developed to deal …

Time consistent equilibria in dynamic models with recursive payoffs and behavioral discounting
We prove existence of time consistent equilibria in a wide class of dynamic models with recursive payoffs and generalized discounting involving both behavioral and normative applications. Our generalized Bellman equation method identifies and separates both: …

Evolution of populations with strategy-dependent time delays
We study the effects of strategy-dependent time delays on equilibria of evolving populations. It is well known that time delays may cause oscillations in dynamical systems. Here we report a novel behavior. We show that …

A new SEIR type model including quarantine effects and its application to analysis of COVID-19 epidemic in Poland in March-April 2020
Tomasz Piasecki is going to present recent results of a joint work with Piotr B. Mucha (University of Warsaw) and Magdalena Rosińska (National Institute of Public Health - National Institute of Hygiene). *** Contact tracing …

The role of indirect prey-taxis and interference among predators in pattern formation
It is important to find biological factors that may lead to formation of patches in the distribution of species. We build a simple model describing a consumer/predator which, besides random dispersion, searches for food by …

The big unknown: The asymptomatic spread of COVID-19
This talk draws attention to the asymptomatic and mildly symptomatic cases of COVID-19, which, according to some reports, may constitute a large fraction of the infected individuals. These cases are often unreported and are not …

Automated data collection from bitmap images on Polish Health Ministry's Twitter. Some thoughts on COVID-19 statistics in Poland.
I will only briefly focus on the technicalities. Polish Ministry of Health publishes a large part of the coronavirus-related data only in the form of bitmap images on Twitter. I wrote a set of Python …

Evolutionary analysis and modeling of coronavirus genomes
Studies have shown that novel coronavirus (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19) most likely was transmitted to humans by animal carriers. It is therefore interesting to ask how the virus has evolved in organisms of …
