Classical and quantum cosmology of Fab Four John theories
Physics Letters B, 2019 We study the John term of Fab Four cosmology in the presence of a scalar potential. We show here how this theory can describe a wide range of cosmological solutions.

Journal of Geophysical Research: Space Physics, Volume 130, Issue 9, September 2025.Abstract Vibrationally excited nitrogen molecules (N2) play an important role in the chemistry and dynamics of Earth's atmosphere. Electron impact, whether it originates from auroral precipitation or ionospheric thermal electrons, is among the major causes of the vibrational excitation of N2.

Magnetic Mineralogy in Lunar Mare Basalts and Implications for Paleointensity Retrieval
Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract Lunar paleomagnetic studies have identified multidomain metallic Fe–Ni alloys as the dominant magnetic contributors in mare basalts. Here, we explore the low‐temperature magnetic behavior of standard samples for a suite of opaque minerals that occur within mare basalts (single‐domain and multidomain Fe, wüstite, ulvöspinel, iron chromite ...

Journal for the Theory of Social Behaviour, Volume 55, Issue 3, September 2025.ABSTRACT This article introduces immanent idealism as an alternative path in social ontology and theory. It argues for a distinction between three basic ontological dimensions, the ideational, the institutional and the structural. This approach highlights the cognitional priority of worldviews as the core element of the ideational dimension, and it ...

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.

Magnesium phosphate in the Cold Bokkeveld (CM2) carbonaceous chondrite
Meteoritics &Planetary Science, Volume 60, Issue 9, Page 2017-2032, September 2025.Abstract Hydrous Mg‐phosphate was first described from astromaterials in particles returned from the C‐type asteroid Ryugu, and has subsequently been found in samples of the B‐type asteroid Bennu and CI1 carbonaceous chondrites. This phase may have been highly significant as a source of bioessential compounds for early Earth.

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 16, 28 August 2025.Abstract The first time‐resolved leader spectra associated with a downward Terrestrial Gamma‐ray Flash (TGF) observed by the Telescope Array Surface Detector (TASD) were recently reported by Kieu et al. (2024, https://doi.org/10.1029/2024JD041720). Building on that study, this paper presents the time‐resolved leader spectra of two additional downward ...

Cosmology from quantum potential
Physics Letters B, 2015 It was shown recently that replacing classical geodesics with quantal (Bohmian) trajectories gives rise to a quantum corrected Raychaudhuri equation (QRE).

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 ...
