Comparison of primordial tensor power spectra from the deformed algebra and dressed metric approaches in loop quantum cosmology [PDF]
, 2015 Loop quantum cosmology tries to capture the main ideas of loop quantum gravity and to apply them to the Universe as a whole. Two main approaches within this framework have been considered to date for the study of cosmological perturbations: the dressed ...

Global and Sequential Imaging Observation of the Earth's Plasmasphere by PHOENIX Onboard EQUULEUS
Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.Abstract The Plasmaspheric Helium ion Observation by Enhanced New Imager in eXtreme ultraviolet (PHOENIX) onboard EQUilibriUm Lunar‐Earth point 6U Spacecraft (EQUULEUS) performed global imaging observations of the Earth's plasmasphere from a meridian view. PHOENIX is a normal‐incidence telescope designed to observe He II emission at 30.4 nm, consisting

Generalized effective description of loop quantum cosmology [PDF]
, 2015 The effective description of loop quantum cosmology (LQC) has proved to be a convenient platform to study phenomenological implications of the quantum bounce that resolves the classical big-bang singularity. Originally, this description was derived using

Enemies: uneasy accompaniments in late life Ennemis : accompagnements de fin de vie difficiles
Journal of the Royal Anthropological Institute, Volume 31, Issue S1, Page 128-144, April 2025.Against a phenomenological orientation to ageing as path or course, a contrastive frame is offered around a figure termed the enemy. Four distinctive ethnographic fragments are utilized: (1) a Polish‐Jewish migrant to Canada in her late eighties who listens continually to the radio and worries over the malign forces in the world that the radio ...

Gravitational Fluctuations as an Alternative to Inflation
Universe, 2019 The ability to reproduce the observed matter power spectrum P ( k ) to high accuracy is often considered as a triumph of inflation. In this work, we explore an alternative explanation for the power spectrum based on nonperturbative quantum field ...

Dreaming Ubuntu: Jungian Studies, Forgiveness, and Jung’s Recalcitrant Fourth
Journal of Analytical Psychology, Volume 70, Issue 2, Page 235-256, April 2025.Abstract Jung’s recalcitrant fourth comes in from a place of opposition, demanding that what has been neglected be considered. It is in the spirit of the fourth that the author examines the use of Ubuntu in Jungian literature, cautioning against a decontextualized appropriation of the notion that overlooks its diverse interpretations and usages ...

A DISCOURSE ANALYSIS THROUGH CORPUS LINGUISTICS ON THE CASE OF POPULAR SCIENCE BOOK THE GRAND DESIGN
Kajian Linguistik dan Sastra, 2016 This study aims to discover the theme of popular physics book, The Grand Design, through corpus linguistics and discourse analysis as well as how the authors of the book describe the field of study which in fact is not their main focus to work on.

Inflation with the Starobinsky potential in loop quantum cosmology [PDF]
, 2015 A self-consistent pre-inflationary extension of the inflationary scenario with the Starobinsky potential, favored by Planck data, is studied using techniques from loop quantum cosmology (LQC).

Gravitational Fluctuations as an Alternative to Inflation II. CMB Angular Power Spectrum
Universe, 2019 Power spectra always play an important role in the theory of inflation. In particular, the ability to reproduce the galaxy matter power spectrum P ( k ) and the CMB temperature angular power spectrum C l ’s to high accuracy is often ...

Quantum Cosmology in the Light of Quantum Mechanics [PDF]
Galaxies, 2019 There is a formal analogy between the evolution of the universe, when this is seen as a trajectory in the minisuperspace, and the worldline followed by a test particle in a curved spacetime. The analogy can be extended to the quantum realm, where the trajectories are transformed into wave packets that give us the probability of finding the universe or ...
