Dark matter (DM) with a mass below few keV must have phase space distribution that differs substantially from the Standard Model particle thermal space: otherwise, it will free stream out of cosmic structures as they form. We observe fermionic DM $\ensuremath{\psi}$ in this range non-negligible momentum early Universe, even total absence kinetic energy. This is because fermions were inevitably ...

Since Cauchy numbers were introduced, various types of Cauchy numbers have been presented. In this paper, we define degenerate Cauchy numbers of the third kind and give some identities for the degenerate Cauchy numbers of the third kind. In addition, we give some relations between four kinds of the degenerate Cauchy numbers, the Daehee numbers and the degenerate Bernoulli numbers.

In 90 days neurotoxicity the number of degenerate mylinated nerve fiber were fewer than in acute neurotoxicity. The study consist of 4 groups as untreated control, low dose, intermediate dose and high dose. Control group was dosed orally daily for 90 days with corn oil, low dose group dosed with 1.25 mg/kg of TOCP, intermediate group dosed with 2.5mg/kg of TOCP and high dose group dosed with 5m...

Horava gravity breaks Lorentz symmetry by introducing a dynamical timelike scalar field (the khronon), which can be used as preferred time coordinate (thus selecting space-time foliation). Adopting the khronon coordinate, theory is invariant only under reparametrizations and spatial diffeomorphisms. In infrared limit, this sometimes referred to khronometric theory. Here, we explicitly construct...

Kundt spacetimes are of great importance in general relativity in 4 dimensions and have a number of topical applications in higher dimensions in the context of string theory. The degenerate Kundt spacetimes have many special and unique mathematical properties, including their invariant curvature structure and their holonomy structure. We provide a rigorous geometrical kinematical definition of ...
