A Study of the Residual 39Ar Content in Argon from Underground Sources

open access: yes, 2012
The discovery of argon from underground sources with significantly less 39Ar than atmospheric argon was an important step in the development of direct-detection dark matter experiments using argon as the active target.

Learning Wave Scattering Properties From Seismograms

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Heterogeneities in the Earth's crust scatter seismic waves at many scales, trapping seismic energy and producing coda waves that encode valuable information on geological structures. In regions such as volcanoes and fault systems, analyzing coda waves is essential for characterizing non‐uniform subsurface heterogeneity, improving ...

Thermal and Catalytic Cracking of JP-10 for Pulse Detonation Engine Applications [PDF]

open access: yes, 2002
Practical air-breathing pulse detonation engines (PDE) will be based on storable liquid hydrocarbon fuels such as JP-10 or Jet A. However, such fuels are not optimal for PDE operation due to the high energy input required for direct initiation of a ...

Goldilocks: American Precious Metals and the Rise of the West

open access: yesReview of Income and Wealth, Volume 72, Issue 1, February 2026.
ABSTRACT We estimate the contribution of the American precious metal windfall to Western Europe's growth performance in the early modern period. The exogenous nature of American precious metal extraction allows for the identification of monetary effects.

Tracking Subsurface Changes via Frequency Shifts in Volcanic Tremor Spectral Lines: Observations From Mt Etna

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Episodes of volcanic tremor provide valuable insights into the dynamics of subsurface processes at active volcanoes. Previous studies have suggested that evolving tremor properties may relate to changes in the stress conditions of the plumbing system. However, a strong causative link has remained elusive.

Advancing Lithium‐Mediated Nitrogen Reduction using Insights from Lithium‐Ion Battery: Focusing on Uniform Li Plating

open access: yesAdvanced Energy Materials, Volume 16, Issue 1, 7 January 2026.
Cross‐pollination from lithium metal batteries (LMBs) systematically accelerates lithium‐mediated nitrogen reduction (Li‐NRR). Battery‐derived strategies—solid‐electrolyte interphase (SEI)/interface engineering, solvation‐structure and electrolyte design, applying additives—translate into higher Faradaic efficiency (FE), energy efficiencyt (EE), and ...

Hindu–Muslim Alliances at Ahmedabad's Double Frontier

open access: yesAntipode, Volume 58, Issue 1, January 2026.
ABSTRACT This paper develops the concept of double frontiers—urban sites where capitalist accumulation and ethno‐territorial ordering are articulated—to examine communal capitalism as a mode of authoritarian rule in contemporary India. Focusing on Ahmedabad, India's most segregated city, it shows how segregation shifted after the 2002 pogrom from ...

Upper Cretaceous Seismic Stratigraphy and Magma‐Enhanced Petroleum System of the Offshore Indus Basin

open access: yesBasin Research, Volume 38, Issue 1, January–February 2026.
Seismic data reveals Cretaceous stratigraphy and hydrocarbon potential beneath volcanic rocks in Offshore Indus Basin, where magmatic intrusions enhanced source rock maturation and hydrocarbon generation by 8%–18% during favourable timing coinciding with Deccan volcanism.

Upper mantle magma storage and transport under a Canarian shield-volcano, Teno, Tenerife (Spain) [PDF]

open access: yes, 2008
We use clinopyroxene-liquid thermobarometry, aided by petrography and mineral major element chemistry, to reconstruct the magma plumbing system of the late Miocene, largely mafic Teno shield-volcano on the island of Tenerife.
