Tadpole Cosmology: Self Tuning Without Degeneracy

DNA sequence representation without degeneracy.

Graphical representation of DNA sequence provides a simple way of viewing, sorting and comparing various gene structures. A new two-dimensional graphical representation method using a two- quadrant Cartesian coordinates system has been derived for mathematical denotation of DNA sequence. The two-dimensional graphic representation resolves sequences' degeneracy and is mathematically proven to el...

Numerical Coincidences and 'tuning' in Cosmology

Towards quantum cosmology without singularities.

In this paper we investigate the vanishing of cosmological singularities by quantization. Starting from a 5d Kaluza{Klein approach we quantize, as a rst step, the non{spherical metric part and the dilaton eld. These elds which are classically singular become smooth after quantization. In addition, we argue that the incorporation of non perturbative quantum corrections form a dilaton potential. ...

Braneworld Cosmology Almost without Branes

We review some general aspects of braneworld cosmologies in which an inflationary period driven by a scalar field confined on the brane is described by a nonstandard effective Friedmann equation. The perturbation spectra, consistency equations and observational consequences of these models are considered.

Concordance cosmology without dark energy

According to the separate universe conjecture, spherically symmetric sub-regions in an isotropic universe behave like mini-universes with their own cosmological parameters. This is an excellent approximation in both Newtonian and general relativistic theories. We estimate local expansion rates for a large number of such regions, and use a scale parameter calculated from the volumeaveraged incre...
