A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

open access: yesSedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Cavitating Inducer Instabilities: Experimental Analysis and 2D Numerical Simulation of Unsteady Flow in Blade Cascade

open access: yes, 2001
Cavitating flows in rocket engine turbo-pump inducers are studied by experimental and numerical ways. The experimental analysis focused on the cavitating structures at the periphery of the inducer, the quantification of the vapour volume at inducer inlet,

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

open access: yesSedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Dead time, hard time, and narrative redemption: Delimiting the life proper

open access: yesThe Southern Journal of Philosophy, EarlyView.
Abstract Is every detail of your life a candidate for the meaningful, valuable, or worthwhile? If not, which do you exclude? Thaddeus Metz nominates “dead time”: the nail‐clipping, line‐waiting, traffic‐jam enduring, generally commonplace moments of our life. Dead time, while prevalent, is not remarkable. Metz recommends that we set at least some of it

Comparative Gas‐Brine Relative Permeability of H2, N2, and CO2 Under Subsurface Storage Conditions

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Gas‐brine relative permeability controls subsurface gas storage, including underground hydrogen and CO2 storage. Here, we measure steady‐state gas‐brine relative permeabilities for H2, N2, and CO2 in a sandstone core at 0.1–6 MPa under identical conditions.

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 7, Page 804-839, July 2026.
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for
