The E-Cohomological Conley Index, Cup-Lengths and the Arnold Conjecture on T 2n
PublicationWe show that the E-cohomological Conley index, that was introduced by the first author recently, has a natural module structure. This yields a new cup-length and a lower bound for the number of critical points of functionals on Hilbert spaces. When applied to the setting of the Arnold conjecture, this paves the way to a short proof on tori, where it was first shown by C. Conley and E. Zehnder in 1983.

Cancer stem cells and escape from drug-induced premature senescence in human lung tumor cells: implications for drug resistance and in vitro drug screening models
PublicationBadania z użyciem modelu komórek nowotworu płuc A549 wykazały, że komórki te po traktowaniu lekami uszkadzającymi DNA zatrzymują proliferację i wchodzą w stan starzenia komórkowego. Jednak post-inkubacja tych komórek prowadzi do powrotu do stanu proliferacji małej frakcji komórek. Wykazaliśy, że frakcja ta związana jest z obecnością komórek pierwotnych nowotworu w populacji komórek A549. Powrót do stanu proliferacji komóek A549...

Noise and Rolling Resistance Properties of Various Types of Winter Tyres Compared to Normal Car Tyres
PublicationTo cope with winter weather conditions, potentially including snow and ice, it is common to use winter tyres, or ”all-seasons” tyres assumed to be safe both in summer and winter. In some northern countries, winter tyres are mandatory. Traditionally, it has been assumed that winter tyres are noisier than normal tyres (here called summer tyres) and winter tyres equipped with studs are assumed to be very noisy.This paper presents...

Speed estimation of a car at impact with a W-beam guardrail using numerical simulations and machine learning
PublicationThis paper aimed at developing a new method of estimating the impact speed of a passenger car at the moment of a crash into a W-beam road safety barrier. The determination of such a speed based on the accident outcomes is demanding, because often there is no access to full accident data. However, accurate determination of the impact speed is one of the key elements in the reconstruction of road accidents. A machine learning algorithm...
