Testability and Epistemic Shifts in Modern Cosmology [PDF]

open access: yes, 2012
During the last decade new developments in theoretical and speculative cosmology have reopened the old discussion of cosmology’s scientific status and the more general question of the demarcation between science and non-science. The multiverse hypothesis,

Inter‐episodic Tremor and Slip Event Episodes of Quasi‐spatiotemporally Discrete Tremor and Very Low Frequency Earthquakes in Cascadia Suggestive of a Connective Underlying, Heterogeneous Process

open access: yesGeophysical Research Letters, 2020
Exploring relationships between different types of slow earthquakes is essential for determining their source properties and controlling parameters. Studies show that very low frequency earthquakes (VLFEs) and tremor are discrete events that necessitate ...

Characterization of coesite‐bearing impact melt glass from the Hapcheon crater, Korea: Trimodal phase architecture, shock metamorphism, and implications for 40Ar/39Ar geochronology

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We present the first micrometer‐scale, phase‐resolved compositional characterization of impact melt glass from the Hapcheon crater (~1.4 km apparent diameter), the first confirmed impact structure on the Korean Peninsula, integrating EPMA‐WDS (5 μm spot), confocal Raman spectroscopy (<1 μm spot), XRD, and 40Ar/39Ar step‐heating geochronology ...

The Influence of the Stretch of Mini‐Magnetospheres Formed by Crustal Fields on the Martian Bow Shock Location

open access: yesGeophysical Research Letters
Mars lacks an intrinsic dipolar magnetic field but possesses strong crustal magnetic fields scattered across its surface. There has been an ongoing debate about how these crustal fields influence the bow shock, the outermost plasma boundary of the ...

A Long‐Term View of Episodic Tremor and Slip in Cascadia

open access: yesGeophysical Research Letters, 2020
Episodic Tremor and Slip, or ETS, is a well‐recognized phenomenon in the Cascadia subduction zone. Constraining the precise location of geodetically measured slip during ETS is important for clarifying the relationship between slip and tremor during ETS,

How much history can chemistry take? [PDF]

open access: yes, 2010
Chemistry is typically considered to be a nomothetic science, i.e. science interested in general laws rather than historical facts. Also, the unification of science is usually envisioned as an effort to connect particular scientific disciplines through ...

Nonlinear Impacts of Surface Exchange Coefficient Uncertainty on Tropical Cyclone Intensity and Air‐Sea Interactions

open access: yesGeophysical Research Letters, 2020
Tropical cyclone maximum intensity is believed to result from a balance between the surface friction, which removes energy, and a temperature/moisture (enthalpy) difference between the sea surface and the air above it, which adds energy.

No Degree, No Lab, No Borders: An Independent Researcher's Journey From Yemen to Global Science

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract I grew up in Yemen with a dream to study space, but my country had no astronomy programs, no universities for astrophysics, and soon, no stable peace. This Perspective is a personal and systemic account of how I pursued planetary science from a conflict zone—with no smartphone, no home internet, no supervisor, and no institutional backing.

The ARGO-YBJ experiment in Tibet [PDF]

open access: yes, 2001
The ARGO-YBJ experiment (Astrophysical Radiation Ground-based Observatory at YangBaJing) is under construction in Tibet, 90 km to the north of Lhasa. The full coverage approach and the high altitude location allow the study of many physics items in the ...

Muography with nuclear emulsions - Stromboli and other projects [PDF]

open access: yes, 2017
The muon radiography is a novel imaging technique to probe the volca- noes interior, using the capability of high energy cosmic ray muons to penetrate large thicknesses of rock.
