Magnetic flux emergence in fast rotating stars

open access: yes, 2007
Fast rotating cool stars are characterised by high magnetic activity levels and frequently show dark spots up to polar latitudes. Their distinctive surface distributions of magnetic flux are investigated in the context of the solar-stellar connection by ...

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Spontaneous Contact and Social Resilience Following Eruption of Interethnic Violence in Ethnically Mixed Settings

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT Does spontaneous contact between individuals from different ethnonational groups affect their social resilience, specifically their ability to avoid escalation and radicalization following eruptions of ethnic violence? To address this question, we conducted a series of studies in mixed Jewish–Palestinian cities and academic settings.

Itinerant curriculum theory: People's theory against the field's epistemicidal ethos

open access: yesThe Curriculum Journal, EarlyView.
Abstract The field of curriculum studies suffers from a glaring theoretical impasse. Much of this impasse has been rightly attributed to the triumphalism of the neoliberal wave that has massacred the educational hemisphere with policies and practices that reduce pedagogy to an instrumentalist praxis directly associated with the thirsty desires and ...

Lacustrine and fan‐delta sediments in syn‐rift lake basins

open access: yesThe Depositional Record, EarlyView.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

The 1723 AD violent Strombolian and phreatomagatic eruption at Irazu volcano (Costa Rica) [PDF]

open access: yes, 2013
The largest of the recorded historic eruptions at Irazú volcano began on February 16, 1723 and lasted until at least December 11. We here critically examine deposits of this eruption exposed on the summit of Irazú. Our reconstruction of the eruption is

Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides)

open access: yesThe Depositional Record, EarlyView.
A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.

Polypharmacy with tiagabine, levetiracetam, and perampanel in status epilepticus: Insights from EEG, biochemical, and histopathological studies in rats

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Status epilepticus (SE) is a condition of neurological emergency, which precipitates various functional and morphological changes in the brain. Due to the risk of drug resistance associated with SE, this study aimed to evaluate a multitargeted approach to treat SE by combining clinically used antiseizure drugs. Methods In this study,

Non‐Hydrostatic Model for Simulating Moving Bottom‐Generated Waves: A Shallow Water Extension With Quadratic Vertical Pressure Profile

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
In this article, we derive a non‐hydrostatic extension to the SWE to solve bottom‐generated waves along with its pressure relation. This relation is built on a linear vertical velocity assumption, leading us to a quadratic pressure profile, where we alternatively write it so that we can solve it by a projection method without ambiguity due to the ...
