Benchmark Test of Drift-kinetic and Gyrokinetic Codes through Neoclassical Transport Simulations [PDF]

, 2009
Two simulation codes that solve the drift-kinetic or gyrokinetic equation in toroidal plasmas are benchmarked by comparing the simulation results of neoclassical transport.

Assessment of validity of local neoclassical transport theory for studies of electric-field root-transitions in the W7-X stellarator

Nuclear Fusion
The neoclassical ambipolarity condition governing the radial electric field in stellarators can have several solutions, and sudden transitions (in radius) between these can then take place. The radial position and structure of such a transition cannot be

Mergers and Acquisitions as Navigators of Climate Policy Shocks: Evidence from the NOx Budget Trading Program

Financial Management, EarlyView.
ABSTRACT We examine how mergers and acquisitions (M&As) enable firms to adapt to climate policy shocks. Exploiting the adoption of the Nitrogen Oxides (NOx) Budget Trading Program (NBP) across US states as an exogenous shock, we find that firms with NOx‐emitting plants subject to the NBP are more likely to engage in M&As, particularly through vertical ...

Impurity transport and bulk ion flow in a mixed collisionality stellarator plasma

, 2017
The accumulation of impurities in the core of magnetically confined plasmas, resulting from standard collisional transport mechanisms, is a known threat to their performance as fusion energy sources.

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

Fisheries Management and Ecology, EarlyView.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing

IN PURSUIT OF THE HOFFMANNESQUE

German Life and Letters, EarlyView.
ABSTRACT This article seeks to elucidate the term ‘Hoffmannesque’ — the eponymous adjective that refers to E. T. A. Hoffmann — through recourse to Hoffmann's own use of ‘esque’ words: arabesque, grotesque, burlesque, picturesque. By investigating the characteristics of ‘esque’ formulations and tracing their recurrence through Hoffmann's texts, I argue ...

Study of Finite-Orbit-Width Effect on Neoclassical Transport in Tokamak Core Region [PDF]

, 2003
Neoclassical transport simulation using the δ f Monte-Carlo method is carried out to investigate the finite-orbitwidth (FOW) effect on the transport near the magnetic axis.

Time-dependent full-radius integrated modeling of the DTT tokamak main plasma scenarios

Nuclear Fusion
We use an integrated modeling workflow with the transport code ASTRA coupled with the quasi-linear transport model TGLF-SAT2, the neoclassical model NCLASS, the FACIT model for the neoclassical impurity transport and the IMEP routines for the pedestal ...

The Legacy of Policy Inaction in Climate‐Growth Models

International Economic Review, EarlyView.
ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.
