Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts
Advanced Science, Volume 13, Issue 5, 27 January 2026.The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

Spatial structure of an individual Mn acceptor in GaAs [PDF]
, 2004 The wave function of a hole bound to an individual Mn acceptor in GaAs is spatially mapped by scanning tunneling microscopy at room temperature and an anisotropic, cross-like shape is observed. The spatial structure is compared with that from an envelope-

Ecology and Evolution, Volume 16, Issue 1, January 2026.A good positive correlation was found between maximum temperature and burn area; increased temperature relates to an increase in fire activity and larger burn areas. Grassland and needle leaf forests are the major land cover types with relatively high fire frequency, likely due to flammable biomass and seasonal dryness, while broad leaved closed ...

Simplified models for photohadronic interactions in cosmic accelerators
, 2010 We discuss simplified models for photo-meson production in cosmic accelerators, such as Active Galactic Nuclei and Gamma-Ray Bursts. Our self-consistent models are directly based on the underlying physics used in the SOPHIA software, and can be easily ...

The Quasar Main Sequence explained by the combination of Eddington ratio, metallicity and orientation [PDF]
, 2019 We address the effect of orientation of the accretion disk plane and the geometry of the broad-line region (BLR) as part of an effort to understand the distribution of quasars in the optical plane of the quasar main sequence.

Community structure and range shifts in Arctic marine fish under climate change
Ecography, Volume 2026, Issue 1, January 2026.Arctic marine ecosystems are rapidly transforming due to climate change. Warming temperatures and shrinking sea ice are enabling boreal fish to expand northward, possibly disturbing cold‐adapted Arctic species assemblages. Species range shifts have been documented in the Bering and Barents Seas, raising concerns about ecosystem restructuring.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Fluids can modify the mechanical properties of rocks, including shear strength and strain behavior. We investigate the timing and magnitude of seismic events during fault motion in strike–slip systems across the Peloritani Mountains (northeastern Sicily) and Aeolian Archipelago using GNSS and seismological data analysis.

Analysis of oscillations of atmospheric neutrinos [PDF]
, 2000 We briefly review the current status of standard oscillations of atmospheric neutrinos in schemes with two, three, and four flavor mixing. It is shown that, although the pure \nu_\mu-->\nu_\tau channel provides an excellent 2\nu fit to the data, one ...
