Outsmarting sanctions

open access: yesAmerican Ethnologist, Volume 53, Issue 1, Page 34-44, February 2026.
Abstract In 2012 the UN Security Council and the European Union bolstered US economic sanctions on Iran, disembedding the country's economy from financial markets. Since then, the sanctions have radically devalued Iran's currency, leading Iranians to seek a viable standard of value elsewhere. They have done so through ghachagh (fugitive) configurations

Brane inflation: A field theory approach in background supergravity

open access: yes, 2012
We propose a model of inflation in the framework of brane cosmology driven by background supergravity. Starting from bulk supergravity we construct the inflaton potential on the brane and employ it to investigate for the consequences to inflationary ...

Coordinate‐ and Spacetime‐Independent Quantum Physics

open access: yesAnnalen der Physik, Volume 538, Issue 1, January 2026.
This article studies in the framework of quantum field theory in curved spacetime, if there exists a single zero‐rank‐tensor solution of a Klein‐Gordon PDE, being valid at once for the depicted spacetimes. The answer is shown to be affirmative, even for a class of such solutions having the standard applications in particle physics. ABSTRACT The concept

Kaluza-Klein cosmological inflation

open access: yesNuclear Physics B, 1985
Abstract We discuss cosmological inflation resulting from slow rollover to equilibrium of the radius of the compact manifold in Kaluza-Klein theories. Reheating of the universe after this inflation, and the spectrum of density fluctions are also considered.

Was the Inca Economy Based on “Protomoney”? Or, Why Accounting Systems Should Not Be Conflated With Concepts of Exchange Value

open access: yesEconomic Anthropology, Volume 13, Issue 1, January 2026.
ABSTRACT The khipu knotted string records in the ancient Andes were accounting systems, but they did not indicate any concepts of commensurability or exchange value. They were not incipient money; instead, monetized commerce appears to have predated the economic organization of the Inca society. The article begins by tracing the emergence of coinage in

Stability of Accelerating Cosmology in Two Scalar-Tensor Theory: Little Rip <em>versus</em> de Sitter

open access: yesEntropy, 2012
We develop the general reconstruction scheme in two scalar model. The quintom-like theory which may describe (different) non-singular Little Rip or de Sitter cosmology is reconstructed.

The cosmological heavy ion collider: Fast thermalization after cosmic inflation

open access: yesPhysics Letters B, 2020
Heavy-ion colliders have revealed the process of “fast thermalization”. This experimental break-through has led to new theoretical tools to study the thermalization process at both weak and strong coupling.

Inflation from Extra Dimensions

open access: yes, 1994
A gravity-driven inflation is shown to arise from a simple higher dimensional universe. In vacuum, the shear of $n>1$ contracting dimensions is able to inflate the remaining three spatial dimensions.

Evaluating Multipoint Sampling of Global‐Scale High‐Latitude Electrodynamics by the Geospace Dynamics Constellation

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract The Geospace Dynamics Constellation (GDC) mission aims to investigate the dynamic coupling between the magnetosphere, ionosphere, and thermosphere by resolving key spatiotemporal processes at scales ranging from local to global. A key aspect is GDC's ability to reconstruct hemispheric‐scale high‐latitude electrodynamics with comprehensive ...
