\section{Introduction} The fading channel is a widely adopted time-varying model for real-world wireless communications. In this model, the channel gain changes over time satisfying a certain distribution, called the channel distribution information (CDI). In a block fading channel model, the channel gain is assumed t...

\section{Introduction} There are two well-motivated possibilities for generating the baryon asymmetry at high temperatures: right-handed neutrino leptogenesis and the Affleck-Dine baryogenesis \cite{Affleck:1984fy,Dine:1995kz,Dine:2003ax}. The Affleck-Dine mechanism utilises the fact that scalar potentials in supersym...

\section{Introduction} \label{sec:intro} \noindent In Quantum Field Theory (QFT), there exist different representations for the Hilbert space of quantum states. The one used most frequently is the Fock representation (using Dirac's bra-ket notation), in which a general state is a linear combination of $n$-particle sta...

\section{Introduction} \noindent The inflation model \citep{Starobinsky:1979ty,Starobinsky:1980te,Guth:1980zm,Linde:1981mu,Albrecht:1982wi,Sato:1980yn} has been the leading paradigm of the very early Universe in past three decades. Not only does it resolve the flatness, horizon and monopole problems in the hot big-bang...

\section{Introduction} Strachey~\cite{str00} distinguished between {\em ad hoc} and parametric polymorphic functions in programming languages, defining a polymorphic program to be {\em parametric} if it applies the same type-uniform algorithm at each of its type instantiations. Reynolds~\cite{param_reynolds} introduce...

\section{Introduction} Snyder spacetime \cite{Snyder} was introduced in 1947 as an attempt to avoid UV divergences in QFT. By assuming a noncommutative structure of spacetime, and hence a deformation of the Heisenberg algebra, it was possible to define a discrete spacetime without breaking the Lorentz invariance, openi...
