On the Elusive Ninth Vibrational State of the Argon Dimer

open access: yesNatural Sciences, Volume 6, Issue 1, January 2026.
ABSTRACT An unresolved discrepancy between high‐accuracy potential energy curves for the argon dimer (Ar2${\rm Ar}_2$), which support different numbers of bound vibrational states and profoundly different scattering lengths for Ar2${\rm Ar}_2$, is probed by morphing these curves to available spectral data within the reduced potential energy curve ...

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

Calculation Method for Magnetic Saturation Current of Shunt Reactors Under Oscillation in Renewable Energy Power Systems

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
The paper proposes a piecewise analytical method for calculating the winding current and the neutral reactor current under oscillatory conditions in renewable energy power systems. The method is based on the operational state of the core magnetic circuit, where the nonlinear magnetisation curve is approximated by piecewise linear segments with the ...
