NEOCLASSICAL TRANSPORT AND IOTA SCALING IN THE TJ-?????II STELLARATOR [PDF]

, 2016
Neoclassical transport properties are studied in the TJ-II stellarator, taking effective ripple and plateau factor as the figures of merit. Using the DKES code run by grid computing techniques, these two quantities have been estimated as functions of ...

Reduced electrostatic turbulence in the quasi-isodynamic stellarator configuration CIEMAT-QI4

Nuclear Fusion
CIEMAT-QI4 is a quasi-isodynamic stellarator configuration that simultaneously features very good fast-ion confinement in a broad range of β values, low neoclassical transport and bootstrap current, and ideal magnetohydrodynamic stability up to $\beta ...

Reciprocal Tariffs and Systemic Trade Losses: Evidence From Korea, Japan, and the EU

Asia Pacific Viewpoint, EarlyView.
ABSTRACT The resurgence of U.S. protectionism, the proposal of universal reciprocal tariffs targeting major trading partners, poses systemic risks to global trade that existing bilateral analyses have not fully captured. This paper examines the economic consequences of U.S.

STUDY OF L–H TRANSITION AND PEDESTAL WIDTH BASED ON TWO-FIELD BIFURCATION AND FIXED POINT CONCEPTS

Acta Polytechnica, 2015
The L–H transition in magnetic confinement plasmas is investigated on the basis of concepts of two-field bifurcation and fixed-point stability. A set of heat and particle transport equations with both neoclassical and anomalous effects included is used ...

Regulatory compliance and support for altered management of the exotic pet trade

Conservation Biology, EarlyView.
Abstract Globally, the exotic pet trade has contributed to species invasion, disease, and animal welfare risks. Although scientists have advocated for increased trade regulation, the success of management and regulatory efforts depends on compliance by participants in the exotic pet trade. We used a regulatory compliance framework to investigate exotic

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 ...

Neoclassical transport and profile prediction in transport barriers

Physics of Plasmas
Strong gradient regions in tokamaks, such as the pedestal or internal transport barriers, are regions of reduced turbulence where neoclassical transport can play a dominant role. However, standard neoclassical transport theory assumes that the gradient length scales of density, temperature, and potential are of the order of the system size.

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
