Singularities in Inflationary Cosmological Models [PDF]
Universe, 2021 Due to the accelerated expansion of the universe, the possibilities for the formation of singularities has changed from the classical Big Bang and Big Crunch singularities to include a number of new scenarios. In recent papers it has been shown that such singularities may appear in inflationary cosmological models with a fractional power scalar field ...

Inflationary Reheating to Preheating—A Personal Account
UniverseThis is a personal account of the early work that led to what is now known as the preheating stage of inflationary cosmology. The broader applicability of the underlying instability mechanisms in cosmology are indicated.

Early and late universe holographic cosmology from a new generalized entropy
Physics Letters B, 2022 We propose a new four-parameter entropy function that generalizes the Tsallis, Rényi, Barrow, Sharma-Mittal, Kaniadakis and Loop Quantum Gravity entropies for suitable limits of the parameters.

Antinomies of Nativism: Understanding Decoloniality Theory's Affinities with the Global Far Right
Development and Change, EarlyView.ABSTRACT This article examines the peculiar conjuncture of decolonial theory and contemporary far‐right ideology. It argues that their shared fixation on the dualism of native and settler is immanent to the development of advanced capitalism, particularly the sharpening of its contradictory tendency to undermine labour as the source of value, and to ...

Why do Public Debates Escalate? Trigger Points and the Moral Dynamics of “Hot Politics”
The British Journal of Sociology, Volume 77, Issue 4, Page 701-712, September 2026.ABSTRACT Escalating, emotionally charged, and moralized forms of controversy are a central feature of contemporary politics. Our study develops a framework for understanding how political debates between ordinary citizens become heated; why certain issues provoke particularly strong emotions; and how this affective potential is weaponized by ...

5D generalized inflationary cosmology [PDF]
General Relativity and Gravitation, 1995 We consider 5D Kaluza-Klein type cosmological model with the fifth coordinate being a generalization of the invariant ``historical'' time $τ$ of the covariant theory of Horwitz and Piron. We distinguish between vacuum-, off-shell matter-, and on-shell matter-dominated eras as the solutions of the corresponding 5D gravitational field equations, and ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
