Science and Pseudo-science in the Contemporary State Studies in Iran [PDF]

open access: yesدولت‌پژوهی, 2022
Generally speaking, scientific understanding of social phenomena such as government has been based on the evidence and arguments, but in practice, some people have gone astray and changed their direction to pseudo-scientific understanding, to the extent ...

Signatures of neutral evolution in exponentially growing tumors: A theoretical perspective.

open access: yesPLoS Computational Biology, 2021
Recent work of Sottoriva, Graham, and collaborators have led to the controversial claim that exponentially growing tumors have a site frequency spectrum that follows the 1/f law consistent with neutral evolution. This conclusion has been criticized based

Supersymmetry as an Algebraic Approach to the Jaynes-Cumming Model with Stark Shift and Kerr-Like Medium [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research, 2023
Theory of supersymmetry states that in the standard model, each particle has a partner with a spin that differs by half of a unit. So fermions partners are bosons and vice versa.

Reconstruction of Differential Operators with Frozen Argument

open access: yesAxioms, 2022
We study spectral properties of a wide class of differential operators with frozen arguments by putting them into a general framework of rank-one perturbation theory.

Eurocentrism in Samuel P. Huntington’s Concept of the Clash of Civilisations

open access: yesPolish Political Science Yearbook, 2022
The article is dedicated to an issue of Eurocentrism in American political scientist Samuel P. Huntington’s concept of the clash of civilisations. The arguments presented indicate that Huntington’s concept is pure Eurocentric. I start by mentioning a few

Spectrum Aliasing Does not Occur in Case of Ideal Signal Sampling [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2021
A new model of ideal signal sampling operation is developed in this paper. This model does not use the Dirac comb in an analytical description of sampled signals in the continuous time domain. Instead, it utilizes functions of a continuous time variable,

About the Nature of the Spectrum of the Periodic Problem for the Heat Equation with a Deviating Argument [PDF]

open access: yesAbstract and Applied Analysis, 2013
We study the nature of the spectrum of the periodic problem for the heat equation with a lower-order term and with a deviating argument. A significant influence of the lower-order term on the correct solvability of this problem is found. We obtain a criterion for the strong solvability of the above-mentioned problem.

Využití sesazovací listiny Václava IV. v kronikářství říšských měst 15. století

open access: yesStudia Historica Brunensia, 2020
The bad fame of bohemian king Wenceslas IV, which was deposed by the roman electors in 1400, derives also from their well composed deposition letter, since it became the most important explanatory reference to the contemporary historiographers in the ...
