Charge distribution and magnetic interactions in PrBa2Cu3O7 with substitutional defects and oxygen disorder: the ab initio approach
PublicationW artykule zaprezentowano rezultaty kwantowomechanicznych obliczeń ''ab initio: struktury elektronowej układu PrBa2Cu3O7 zawierającego defekty substytucyjne (Pr_Ba) w podsieci barowo-tlenowej oraz wykazującego zaburzoną stechiometrię tlenową (O5). Badane defekty są odpowiedzialne za redystrybucję ładunku w układzie. Defekty Pr_Ba generują silnie zlokalizowane momenty magnetyczne, które oddziałują głównie na płaszczyzny miedziowo-tlenowe.

Entropy Measures of heart rate variability for short ECG datasets in patients with congestive heart failure
PublicationWe investigated the usefulness of entropy measures calculated for short ECG series in distinguishing healthy subjects from patients with congestive heart failure (CHF). Four entropy measures were tested: Approximate Entropy (ApEn), Sample Entropy (SampEn), Fuzzy Entropy (Fuzzy En) and Permutation Entropy (PE), each computed for ECG series of 1000, 500, 250 and 100 RR intervals. We found that with a reduction of the data set length...

The impact of freeze-thaw processes on a cliff recession rate in the face of temperate zone climate change
PublicationFreeze-thaw action is a common type of geomorphological processes eroding cliff faces in the temperate climate zone. In our previous study, we assessed the geomorphological effects of freeze-thaw fluctuations occurring within the cliff of Jeziorsko Reservoir (central Poland). Based on those findings, we have now determined the number of freeze-thaw cycles to assess their historical impact on the studied cliff. We have also traced...

Experimental and theoretical studies on the photodegradation of 2-ethylhexyl 4-methoxycinnamate in the presence of reactive oxygen and chlorine species
Publication2-Ethylhexyl 4-methoxycinnamate (EHMC) is one of the most commonly used sunscreen ingredient. In this study we investigated photodegradation of EHMC in the presence of such common oxidizing and chlorinating systems as H2O2, H2O2/HCl, H2O2/UV, and H2O2/HCl/UV. Reaction products were detected by gas chromatography with a mass spectrometric detector (GC-MS). As a result of experimental studies chloro-substituted 4-methoxycinnamic...
