Artificial neural network as an effective tool to calculate parameters of positron annihilation lifetime spectra
M. Pietrow, A. Miaskowski
The paper presents the application of the multi-layer perceptron regressor model for predicting the parameters of positron annihilation lifetime spectra using the example of alkane…
Detection of light emission produced in the process of positronium formation
M. Pietrow, R. Zaleski, A. Wagner +6
The excess energy emitted during the positronium (Ps) formation in condensed matter may be released as light. Spectroscopic analysis of this light can be a new method of studying t…
Sound emitted by some grassland animals as an indicator of motion in the surroundings
Marek Pietrow, Piotr Słomski, Bartosz Tkaczyk +3
It is argued based on the results of both numerical modelling and the experiments performed on an artificial substitute of a meadow that the sound emitted by animals living in a de…
Cellular Automaton-Like Model of Arising Physical-Like Properties
Marek Pietrow
A simple relation of the order of abstract objects generates an dimensional basis of three dimensional vectors. A cellular automaton-like model of evolution of this syste…
Application of the theory of excitons to study of the positronium in matter. Optical transition during positronium formation in matter
M. Pietrow
Considerable similarity between positronium atom and an exciton in a quantum dot is indicated. Following this, we apply the calculation regime from the theory of excitons to descri…
Evidence for weakly bound electrons in non-irradiated alkane crystals. The electrons as a probe of structural differences in crystals
M. Pietrow, M. Gagos, L. E. Misiak +4
It is generally assumed that weakly bound (trapped) electrons in organic solids come only from radiolytical (or photochemical) processes like ionization caused by an excited positr…
