On the basis of three different force fields the zero point average structure of dimethylsulfoxide has been calculated. Three different types of calculation were performed. It is found that the different force fields virtually do not affect the resulting parameters while the results from different types of calculation agree within three times the standard errors. The asymmetry of the methyl gro...

Background: To clarify the mechanism of sperm penetration through the zona pellucida, the flagellar force generated by a hyperactivated spermatozoon was evaluated using the resistive force theory applied to the hyperactivated flagellar waves that were obtained from the mammalian spermatozoa. Materials and Methods: The hydrodynamic calculation of the flagellar force of the activated (non-hyperac...

We show that a special choice of light-cone gauge can greatly simplify the calculation of the classical color field created in the initial stages of nucleus-nucleus collisions. Within this gauge, we can in particular construct explicitly the conserved color current and calculate exactly the gauge field immediately after the collision. This field is used as a boundary condition in an iterative s...

This thesis concerns the development of a numerical software tool for propagating and visualising orbits of artificial bodies orbiting the Earth and the calculation of magnetic conjunctions between these objects and the ground. The developed toolbox Î× ËËØ enables the users to visualise the trajectories of satellites under different parameters and to estimate the visibility of a satellite to ma...

We demonstrate how an iterative method for potential inversion from distribution functions developed for simple liquid systems can be generalized to polymer systems. It uses the differences in the potentials of mean force between the distribution functions generated from a guessed potential and the true distribution functions to improve the effective potential successively. The optimization alg...

Casmir forces of massive fermionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. It is shown that in the range of ma ≫ 1 where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields Casimir force for each degree of freedom. We argue this equality exi...

This paper takes a typical 220 kV three-phase three-limb oil-immersed transformer as an example, this paper building transient field-circuit coupled model and 3D coupled magneto -fluid-thermal model. Considering a nonlinear B–H curve, the magneto model uses the field-circuit coupled finite element method (FEM) to calculate the magnetic flux distribution of the core and the current distribution ...

Lagrangian of a massive particle with spin 3 2 is considered in the Rarita-Schwinger formalism. We discuss implications of the contactand the gauge-transformation on the physical content of free and interacting theories. It is shown that the “contact-invariance” is trivial and has no physical relevance. The requirement of the gauge-invariance of the free lagrangian fixes the off-shell lower-spi...
