Fractal Dimensions of Venusian Lava Flows: New Findings for Atla Regio and Review of Previous Analyses

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract The fractal dimensions of lava flow margins on Earth often correlate with their flow morphologies and have been used to tentatively identify flow morphology on other rocky planets where fine‐scale observations are limited. Previous studies of lava flow margins on Venus have reported fractal dimensions (D) mostly within the range between 1.05 ...

Philosophical Implications of Inflationary Cosmology [PDF]

open access: yes, 2003
Recent developments in cosmology indicate that every history having a nonzero probability is realized in infinitely many distinct regions of spacetime.

Tsallisian Gravity and Cosmology

open access: yesAdvances in High Energy Physics, 2020
In this paper, we adopt the Verlinde hypothesis on the origin of gravity as the consequence of the tendency of systems to increase their entropy and employ the Tsallis statistics.

Disintegration, Salvation, and/or Madness in Dostoevsky

open access: yesInternational Journal of Applied Psychoanalytic Studies, Volume 23, Issue 1, March 2026.
ABSTRACT Psychological fragmentation and derangement suffuse Dostoevsky's fiction. This paper argues that the madness of Dostoevsky characters derives from intense wounds to the self: humiliating lacerations that impel fugue and disintegration. Such vulnerable, frangible characters seek to escape and deny themselves to avoid being seen for who they are.

The Fundamental Roles of the de Sitter Vacuum

open access: yesUniverse, 2020
We overview the fundamental roles of the de Sitter vacuum in cosmology where it is responsible for powering the early inflationary stage(s) and the present accelerated expansion, in black hole physics where it provides the existence of a wide class of ...

Symmetry analysis in inflationary cosmology [PDF]

open access: yesAIP Conference Proceedings, 2019
We approach the cosmological inflation thought symmetries of differential equations. We consider the general inflaton field in a homogeneous Friedmann--Lema\^ıtre--Robertson--Walker spacetime and with the use of conformal transformations we are able to write the generic algebraic solution for the field equations.

Exploring the Formation and Age of Irregular Mare Patches (IMPs) to the Southeast of the Chang'e‐5 Landing Site

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Recently, possible exceptionally young mare volcanic glass beads were discovered in Chang'e‐5 (CE‐5) samples. Isotopic dating suggests an age of approximately 120 Ma, presenting new challenges to existing lunar thermal evolution models. Thus, our research focuses on the source region of Rima Mairan, a branch of Rima Sharp, and its surrounding ...

Frontiers of Inflationary Cosmology

open access: yes, 2001
After a brief review the theory of cosmological perturbations, I highlight some recent progress in the area of reheating in inflationary cosmology, focusing in particular on parametric amplification of super-Hubble cosmological fluctuations, and on the ...

Intrusion‐Induced Forced Folding Model for the Origin of Séítah Formation Domes on the Jezero Crater Floor, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The JPL rover Perseverance's investigations of Jezero crater's floor reveal that the ultramafic Séítah formation and the overlying mafic Máaz formation are deformed into a broad, low‐amplitude structural dome. Mastcam‐Z stereo images processed into digital outcrop models, together with RIMFAX ground‐penetrating radar profiles, were used to ...

Constraining inflationary scenarios with braneworld models and second order cosmological perturbations

open access: yes, 2010
PhDInflationary cosmology is the leading explanation of the very early universe. Many different models of inflation have been constructed which fit current observational data.
