<em>The cosmos is made up of universes in infinite number, having similar structure and properties, embedded one in each other and extended in ascending and descending order.To explain and justify this model, there are three universes so far known to us (a) Geo-Universe (b) Atomic-Universe (c) Energy-Universe. These three are having similar structure and properties, embedded one in each other and extended in ascending and descending order. Of these three, we known some extent about the internal structure and properties of the Geo-Universe but we do not known its external structure. We know som

Abstract:
Strictly speaking, knowledge for every object in educational Universe is limited by ignorance or, in other words, these two components co-exist. However, pedagogy primarily deals with knowledge, its acquisition and retention. It ignores the ignorance, leaving it as a subject for a more generic science of psychology. Similarly, atomic nuclei in real Universe are a subject for a more generic science of physics, being only slightly studied in chemistry. To research on knowledge is by far easier than on ignorance, same as chemical research involving mere electron shells is easier than physical res

Abstract:
Discontinuum physics (DCP) provides the non-arbitrary requirement for excluding the antimatter solutions to Dirac’s equation, resulting in a matter‐antimatter asymmetry. A matter‐antimatter asymmetrical universe then results from coupling the matter‐antimatter asymmetry with (1) the prior DCP proposal that the universe came into existence from a quantum fluctuation of a type of vacuum state with a zero net total energy, (2) allowing this quantum fluctuation to constitute a discontinuity containing the non-arbitrary requirement, with this occurring similar to how DCP showed the atomic absorptio

Abstract:
ABSTRACT It has been suggested recently that three-body recombination of two protons and an electron might be significant in the formation of atomic hydrogen in the early Universe. We demonstrate that this process is completely negligible in the primordial plasma and that the value of the redshift, at which the transition from ionized to atomic hydrogen occurs, is determined by an equilibrium between the rates of two-body radiative recombination of a proton and an electron and its inverse, namely photoionization of atomic hydrogen.

Abstract:
Cosmic background (CB) radiation, encompassing the sum of emission from all sources outside our own Milky Way galaxy across the entire electromagnetic spectrum, is a fundamental phenomenon in observational cosmology. Many experiments have been conceived to measure it (or its constituents) since the extragalactic Universe was first discovered; in addition to estimating the bulk (cosmic monopole) spectrum, directional variations have also been detected over a wide range of wavelengths. Here we gather the most recent of these measurements and discuss the current status of our understanding of the

We investigate phenomenologies arising from two distinct sets of modifications introduced in Loop Quantum Cosmology (LQC), namely, the inverse volume and the holonomy corrections. We find scaling solutions in each setting and show they give rise to a period of super-inflation soon after the universe starts expanding. This type of inflation is explicitly shown to resolve the horizon problem with far fewer number of e-foldings compared to the standard inflationary model. Scalar field perturbations are obtained and we demonstrate their near scale invariance in agreement with the latest observatio

Abstract:
In light of the immense compositional diversity of high-entropy materials (HEMs) recently reported (e.g., high-entropy chalcogenides, perovskites, ceramics, etc.) and the relatively amorphous definition of High-Entropy, it is imperative that consistent material classification and benchmarking practices be employed to facilitate comparison between reported figures of merit. In this opinion, an updated form of the numerical high-entropy definition is reviewed, which renders a universal entropy metric applicable to high-entropy alloys and emerging HEMs alike. Analytical methods to verify the exis

Abstract:
Computing the most specific concept (msc) is an inference task that can be used to support the 'bottom-up' construction of knowledge bases for KR systems based on description logics. For description logics that allow for number restrictions or existential restrictions, the msc need not exist, though. Previous work on this problem has concentrated on description logics that allow for universal value restrictions and number restrictions, but not for existential restrictions. The main new contribution of this paper is the treatment of description logics with existential restrictions. More precise

Abstract:
A theory of the vibrational spectra of glasses, based on allowance for the statistical fluctuations of the local elastic constants, is proposed. The existence is established of two characteristic energies h, and h, , dividing the spectrum into regions of qualitatively different behavior of the density of states n (h). At low frequencices w 4 w, the increase of the density of states is determined by the additive contributions of phonons and mutually noninteracting quasilocal vibrations in random soft atomic potentials in the glass. In the intermediate region w , 5 w 5 w, the quasilocal vibratio
