Detrended cross-correlations and their random matrix limit: an example from the cryptocurrency market
Stanisław Drożdż, Paweł Jarosz, Jarosław Kwapień +2
Correlations in complex systems are often obscured by nonstationarity, long-range memory, and heavy-tailed fluctuations, which limit the usefulness of traditional covariance-based…
Parametric Resonance in the Non-Autonomous Sine-Gordon Model
Tomasz Dobrowolski, Jacek Gatlik, Zofia Bryłowska +1
The sine-Gordon model is studied with model parameters that depend on both space and time. An effective model with one degree of freedom is constructed, allowing the description of…
Examining the possibility of a thick crust in the compact stellar object HESS J1731-347
Sebastian Kubis, Włodzimierz Wójcik
A relativistic mean-field model with a crossing term of isovector-scalar and isoscalar mesons, the Cracow crossing terms (CCT) model, has previously been shown to be capable of exp…
Kink Dynamics in a Non-Autonomous Sine-Gordon Model
Tomasz Dobrowolski, Jacek Gatlik, Zofia Bryłowska +1
The sine-Gordon model with space- and time-dependent parameters is considered. A highly accurate effective model with two degrees of freedom is constructed, allowing the descriptio…
Structure, magnetic properties, and cycloidal spin ordering in Nd-doped BiFeO synthesized by sol-gel method
K. Komędera, K. Siedliska, Ł. Gondek +7
In this study, the structural and magnetic properties of Nd-doped BiFeO materials with the formula BiNdFeO were investigated. Samples were prepa…
The Enigma of Gaia18cjb: a Rare Hybrid of FUor and EXor?
Eleonora Fiorellino, Peter Abraham, Agnes Kospal +28
Context. Gaia18cjb is one of the Gaia-alerted eruptive young star candidates which has been experiencing a slow and strong brightening during the last 13 years, similar to some FU…
