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

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 ...

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

Fugitive Junctures: Life‐Seeking, Route‐Finding and the Mobile Ensemble at Kenya's Borders

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Short Abstract Fugitivity has become an important conceptual frame to understand the illegalised mobilities of contemporary migrants in conjunction with enslaved people's historical lines of flight as spatial praxes to seize their own freedom. Thinking from Kenya, and drawing on research with migrants, border officials, activists, police and smugglers,

CFD‐Based and Control‐Oriented Modeling of a Counterflow Heat Exchanger With Utilization of Parameter Identification

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Counterflow heat exchangers (CHXs) thermally couple consumers and producers to a district heating network (DHN). Fluctuating loads and control actions naturally lead to unsteady operation conditions of the network and its components, posing a challenge for DHN models and CHX parameterizations based on Nusselt correlations that assume steady ...
