Gravitational Fluctuations as an Alternative to Inflation III. Numerical Results
Universe, 2020 Power spectra play an important role in the theory of inflation, and their ability to reproduce current observational data to high accuracy is often considered a triumph of inflation, largely because of a lack of credible alternatives.

Transport properties in the Horndeski holographic two-currents model
European Physical Journal C: Particles and Fields, 2023 The transport features of the holographic two-currents model are investigated in the Horndeski gravity framework. This system displays metallic or insulating characteristics depending on whether the Horndeski coupling parameter $$\gamma $$ γ is negative ...

Electron‐Impact Excitation of N2 Is Insufficient to Produce the NO2 Continuum in STEVE
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract The most studied hypothesis for the continuum emission of Strong Thermal Emission Velocity Enhancement (STEVE) is the NO2 ${\text{NO}}_{2}$ continuum. The ion‐impact pathway for this emission was recently shown to be too slow by a few orders of magnitude. In this work, we evaluate the electron‐impact pathway.

Universe, 2022 The hybrid and the dressed metric formalisms for the study of primordial perturbations in Loop Quantum Cosmology lead to dynamical equations for the modes of these perturbations that are of a generalized harmonic-oscillator type, with a mass that depends

Nighttime Westward Equatorial Electrojet Observed During the January 2026 Geomagnetic Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract The equatorial electrojet (EEJ) is a narrow band of zonal electric current flowing in the E‐region ionosphere within approximately ±2° $\pm 2{}^{\circ}$ latitude of the magnetic equator. At night, the EEJ is generally considered very weak because of low ionospheric conductivity.

Weyl's principle, cosmic time and quantum fundamentalism [PDF]
, 2010 We examine the necessary physical underpinnings for setting up the cosmological standard model with a global cosmic time parameter. In particular, we discuss the role of Weyl's principle which asserts that cosmic matter moves according to certain ...

Mixed Magnetocrystalline Anisotropy and the Magnetization of Monoclinic 4C Pyrrhotite
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.Abstract Ferrimagnetic, monoclinic 4C pyrrhotite (Fe7S8), as the iron deficient endmember of the pyrrhotite solid‐solution series (Fe1–xS, 0 < x ≤ 0.125), is the main sulfide mineral widely used in rock and paleomagnetic studies of Earth's crust and extraterrestrial materials. Its particular magnetocrystalline anisotropy (MCA), characterized by an easy

Theologies of Mind: Eriugena and Pratyabhijñā Śaivism
Modern Theology, Volume 42, Issue 4, Page 927-952, October 2026.Abstract Though Eriugena's affinities with several Hindu traditions are clear, this article offers to my knowledge the first detailed discussion of Eriugena's theology in relation to any Indic theological school, here, the nondualist Śaiva tradition known as the Pratyabhijñā (“Recognition”) lineage.

Light‐Imprinted Chirality in Nanomaterials: From Principles to Applications
Advanced Science, Volume 13, Issue 49, 3 September 2026.Light‐induced chirality represents a transformative paradigm for fabricating chiral nanostructures. This review provides a comprehensive framework encompassing light‐based strategies for imprinting and tuning chirality in nanomaterials, which guides researchers in harnessing light to create next‐generation functional materials.
