We consider a family of 1-dimensional Hamiltonian systems consisting of a large number
of particles with on-site potentials and global (long range) interactions. The particles are initially at rest at the equilibrium ...

This thesis explores a model for aggressive brain cancer - glioblastoma multiforme,
with modified gompertzian growth function. Density-dependent diffusion term, taxis,
and growth functions are included in the model that ...

In the Data Science routine, we often face the curse of dimensionality, dealing with
high-dimensional data which, in turn, can be very difficult. The problems of this nature
can be approached by methods of Dimensionality ...

We introduce a new approach to (deterministic) integer factorisation, which could be described in the cryptographically fashionable term of “factoring with hints”: we prove that, for any ϵ > 0, given the knowledge of the ...

We review neural network architectures which were motivated by Fourier series and integrals and
which are referred to as Fourier neural networks. These networks are empirically evaluated in
synthetic and real-world tasks. ...
