The paper is devoted to improving the methodology for conducting laboratory experiments to study the actions of taxpayers. We note that the use of standard economic methods is not enough to study citizens’ behavioral motives (in particular, the des

The traditional one-dimensional (1D) model often fails to accurately predict the dynamic pressure response of large offline air pockets during transients, due to a lack of comprehensive understanding of the underlying mechanisms of transient interact
