The questionable impact of population-wide public testing in reducing SARS-CoV-2 infection prevalence in the Slovak Republic
Jozef Černák
Mina and Andersen, authors of the Perspectives in Science: COVID-19 Testing: One Size Does Not Fit All have referred to results and adopted conclusions from recently published gove…
Low fertility rate reversal: a feature of interactions between Biological and Economic systems
Jozef Černák
An empirical relation indicates that an increase of living standard decreases the Total Fertility Rate (TFR), but this trend was broken in highly developed countries in 2005. The r…
Magnetoresistance of composites based on graphitic disks and cones
Jozef Černák, Geir Helgesen, Fredrik Sydow Hage +1
We have studied the magnetotransport of conical and disk-shaped nanocarbon particles in magnetic fields at temperatures $2\leq T\leq300\:\mathrm{K…
Magnetic properties of carbon nanodisk and nanocone powders
Jozef Cernak, Geir Helgesen, Jozef Kovac +2
We have investigated the magnetic properties of carbon powders which consist of nanodisks, nanocones, and a small fraction of carbon-black particles. Magnetization measurements wer…
Abelian deterministic self organized criticality model: Complex dynamics of avalanche waves
Jozef Cernak
The aim of this study is to investigate a wave dynamics and size scaling of avalanches which were created by the mathematical model {[}J. Černák Phys. Rev. E \textbf{65}, 046141 (2…
Aggregation of magnetic holes in a rotating magnetic field
Jozef Černák, Geir Helgesen
We have experimentally investigated field induced aggregation of nonmagnetic particles confined in a magnetic fluid layer when rotating magnetic fields were applied. After applicat…
