Formation, propagation and conversion of transport barriers triggered by dynamical critical gradient in tokamak plasmas

Nuclear Fusion
In this work, we propose a reduced model with a dynamical critical gradient to study the formation, propagation, and conversion of the transport barriers.

Women's Transitions in the Labor Market and Childbearing: The Challenges of Formal Sector Employment in Indonesia

Population and Development Review, EarlyView.
Abstract It is well established that women's labor force participation drops markedly with marriage and childbearing, however, little is known about women's labor market transitions, especially in developing countries. This article uses the Indonesian Family Life Survey to track the employment histories of over 5000 women for more than 20 years ...

Gyrokinetic prediction of core tungsten peaking in a WEST plasma with nitrogen impurities

Nuclear Fusion
Tungsten peaking is predicted in the core of a WEST plasma with total-f gyrokinetic simulations, including both collisional and turbulent transport. This prediction is validated with a synthetic diagnostic of the bolometry.

Ecological restoration hierarchy as a lens to reveal the foundational economic and legal structures impeding restoration

Restoration Ecology, EarlyView.
Abstract Introduction Biodiversity loss is accelerating due to habitat destruction, economic expansion, and insufficient conservation efforts. Traditional mitigation strategies, which focus on minimizing harm rather than reversing damage, are inadequate for achieving net biodiversity gain. Objectives This article introduces the restoration hierarchy, a

Magnetic-island induced geometric stabilization of turbulence triggering eITB bifurcation

Nuclear Fusion
We demonstrate that geometric deformation of flux-surface induced by a magnetic island can trigger the bifurcation to an electron internal transport barrier (eITB) through a novel positive feedback loop arising from the nonlinear coupling between the ...

Using ASCOT to encode neoclassical collisional physics as prior in fast-ion distribution reconstructions

Nuclear Fusion
Measuring 3D or 4D fast-ion distribution function relies on using prior information in some form due to the ill-conditioned nature of the underlying inverse problem.

On Physical Parameters of the Demonstration Stellarator-Reactor Operating in the Mode of Self-Supported Thermonuclear Reaction

East European Journal of Physics, 2012
With the use of a one-dimensional spatial-temporal numerical code under conditions of ambipolarity of neoclassical transport fluxes the regimes of the self-supported DT-fusion reaction in a reactor-stellarator are calculated.
