We investigate the presence of topological structures and multiple phase transitions in O(3)-sigma model with gauge field governed by Maxwell's term subject to a so-called Gausson's self-dual potential. To carry out this study, it is numerically shown that supports solutions 3-dimensional spacetime. In fact, obtain solutions, we assume spherically symmetrical ansatz find as well some physical b...

Studying the color superconductivity (CSC) phase is important to understand physics in core of neutron stars which only known context where CSC might appear due gravitational force squeezing matter a sufficiently high density. We propose simple holographic dual description transition realistic Yang-Mills theory with power-law Maxwell field. find large number deconfinement phase, not found case ...

Flexible Polyurethane (PU) foam samples with different densities and chemical formulations were tested in quasi-static stress-strain compression tests. The compression tests were performed using the Lloyd LR5K Plus instrument at fixed compression strain rate of 0.033 s-1 and samples were compressed up to 70% compression strains. All foam samples were tested in the foam rise direction and their ...

An instrumental electrode model (IEM) capable of describing the performance of electrical impedance tomography (EIT) systems in the MHz frequency range has been proposed. Compared with the commonly used Complete Electrode Model (CEM), which assumes ideal front-end interfaces, the proposed model considers the effects of non-ideal components in the front-end circuits. This introduces an extra bou...

The Hamiltonian structure of the gauge-free gyrokinetic Vlasov-Maxwell equations is presented in terms a functional and bracket. bracket used to show that angular-momentum conservation law can also be expressed form. Jacobi property demonstrated explicitly.
