Modelling Circumbinary Planets: The case of Kepler-38 [PDF]

open access: yes, 2014
Recently, a number of planets orbiting binary stars have been discovered by the Kepler space telescope. In a few systems the planets reside close to the dynamical stability limit.

The effect of CO2-induced dissolution on flow properties in Indiana Limestone: An in situ synchrotron X-ray micro-tomography study [PDF]

open access: yes, 2019
The injection of CO -rich fluids in carbonate rocks results in an evolution of the pore space, with consequent changes in the hydraulic properties of the reservoir; how these properties evolve, particularly for parameters relevant to multiphase flow e.g.

Single-cone real-space finite difference scheme for the time-dependent Dirac equation

open access: yes, 2014
A finite difference scheme for the numerical treatment of the (3+1)D Dirac equation is presented. Its staggered-grid intertwined discretization treats space and time coordinates on equal footing, thereby avoiding the notorious fermion doubling problem ...

Frequency‐Dependent Seismic Velocity Variations Reveal Layered Aquifer Behavior Under Groundwater Fluctuations

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Frequency‐dependent seismic velocity variations (dv/v) provide depth‐resolved constraints on aquifer behavior under groundwater fluctuations. We analyze 17 years of dv/v time series from ambient noise interferometry in the Chiang Mai Basin, Thailand, and observe contrasting dv/v behavior below and above 1 Hz. By integrating GPS, meteorological,

The Geologic Features of the Occurrence of Copper in North America [PDF]

open access: yes, 1933
Copper is of such widespread natural occurrence in North America and there are so few metal-mining districts that have not contributed to its production that it is obviously necessary in any brief general treatment of the geology of the copper deposits ...

The historical centres of the Dauno Subappenine area: a heritage in danger through abandonment and underestimation of seismic risk

open access: yesArcHistoR Architettura Storia Restauro: Architecture History Restoration, 2020
The Dauni Mountains area (Puglia) is bound to the east by the Tavoliere plain, to the west by the Apennine watershed and is traversed by the mountain chain of the same name. Historical centres of ancient origins cling to these highlands.

Symmetry breaking, Josephson oscillation and self-trapping in a self-bound three-dimensional quantum ball

open access: yes, 2017
We study spontaneous symmetry breaking (SSB), Josephson oscillation, and self-trapping in a stable, mobile, three-dimensional matter-wave spherical quantum ball self-bound by attractive two-body and repulsive three-body interactions.

Association Between Polypharmacy and Socioeconomic and Demographic Factors in Adults Aged 50 Years and Older by Brazilian Macroregions

open access: yesPharmacoepidemiology and Drug Safety, Volume 35, Issue 2, February 2026.
ABSTRACT Purpose This study aimed to investigate the proportions of polypharmacy in the macroregions of Brazil, considering socioeconomic and demographic factors and their associations. Methods A cross‐sectional analysis was conducted using data from the second wave (2019–2021) of ELSI‐Brazil. The outcome was self‐reported polypharmacy.
