Vector field as a quintessence partner

We derive generic equations for a vector field driving the evolution of flat homogeneous isotropic universe and give a comparison with a scalar filed dynamics in the cosmology. Two exact solutions are shown as examples, which can serve to describe an inflation and a slow falling down of dynamical " cosmological constant " like it is given by the scalar quintessence. An attractive feature of vec...

Lactococcus lactis as a live delivery vector

Mucosal surfaces of the body provide a universal entry portal for all known and emerging infectious pathogenic microbes. Therefore, it seems that special vaccination strategies are needed for vaccines that can hinder the entry capability of pathogenic microbes through the mucosal surfaces. Lactic acid bacteria are widely used in the food industry and are presently applied as delivery vehicles i...

The Index of a Vector Field as an Invariant

The purpose of this paper is to demonstrate that the index of a vector field on a smooth manifold is an intrinsic invariant of the manifold. The paper is divided into three sections. The first section introduces the Inverse Function Theorem and provides the proof for the Implicit Function Theorem, laying the foundation for our discussion. In the second section we will introduce the concept of a...

Lorentz transformation as a problem of vector field flow Shao

We study the Lorentz transformation as a vector field flow problem using the 2×2 spinor algebra. The exact, finite Thomas rotation angle is determined and interpreted intuitively. We also establish an invariant and examine the general features of the Lorentz transformation using the phase portraits of the parameters.

Graphic Rendering Considered as a Compilation Chain

Graphical rendering must be fast enough so as to avoid hindering the user perception/action loop. Traditionally, programmers interleave descriptions and optimizations to achieve such performances, thus compromising modularity. In this paper, we consider graphic rendering as a compilation chain: we designed a static and dynamic graphical compiler that enables a designer to clearly separate the d...
