Angular momentum conservation and torsional oscillations in the Sun and solar-like stars

, 2007
The solar torsional oscillations, i.e., the perturbations of the angular velocity of rotation associated with the eleven-year activity cycle, are a manifestation of the interaction among the interior magnetic fields, amplified and modulated by the solar ...

A nested hybridizable discontinuous Galerkin method for computing second-harmonic generation in three-dimensional metallic nanostructures

, 2020
In this paper, we develop a nested hybridizable discontinuous Galerkin (HDG) method to numerically solve the Maxwell's equations coupled with the hydrodynamic model for the conduction-band electrons in metals.

An analytical model for gas overpressure in slug-driven explosions:insights into Strombolian volcanic eruptions [PDF]

, 2012
Strombolian eruptions, common at basaltic volcanoes, are mildly explosive events that are driven by a large bubble of magmatic gas (a slug) rising up the conduit and bursting at the surface.

Enchanting the Otherwise: Magical Realism and the Gendered Ontologies of Organizational Becoming

Gender, Work &Organization, EarlyView.
ABSTRACT This paper enacts a feminist‐posthumanist reimagining of gender as ontological disturbance, using magical realism not as metaphor but as epistemological method. Rejecting representational logics and the managerial rationalities of organizational realism, we advance gender not as identity or role but as spectral interference—a transversal ...

UNIVERSALITY IN THE CLIMATE CATASTROPHE: RETHINKING CHAKRABARTY'S ANTHROPOCENE PHILOSOPHY OF HISTORY WITH MERLEAU‐PONTY'S PHILOSOPHY OF NATURE

History and Theory, EarlyView.
ABSTRACT This article critically examines Dipesh Chakrabarty's concept of Anthropocene history, a philosophy of history that is designed to respond to the universal challenge of the Anthropocene. It uses the work of Maurice Merleau‐Ponty to mitigate the pitfalls of Chakrabarty's concept and to propose an alternative relation between nature and history.

Theory of the sea ice thickness distribution

, 2015
We use concepts from statistical physics to transform the original evolution equation for the sea ice thickness distribution $g(h)$ due to Thorndike et al., (1975) into a Fokker-Planck like conservation law. The steady solution is $g(h) = {\cal N}(q) h^q

An Endogenous ‘Refugee Crisis’: Exploring Frame Drain and Emerging Conflicts in Migration Politics

JCMS: Journal of Common Market Studies, EarlyView.
Abstract Migration governance in Europe is shaped by contesting frames that reflect deeper tensions between security, humanitarianism and sovereignty. This article traces how these frames evolve over time and how the so‐called refugee ‘crisis’ reconfigures framing dynamics and actor relations between 2000 and 2020. Rather than treating the crisis as an
