Integrated modelling of tungsten accumulation control with wave heating: validation in ASDEX Upgrade and predictions for ITER

Nuclear Fusion
In present-day fusion devices, central wave heating is crucial to avoid core tungsten (W) accumulation. In this work, we present an integrated modelling framework that reproduces the reduction of core W peaking in ASDEX Upgrade experiments when multiple ...

What Are The Drivers of Labour Productivity in Italy?

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT This paper introduces a novel sign restriction identification within a structural Bayesian vector autoregression (VAR) to analyse how labour productivity responds to supply and demand shocks and to quantify the contribution of shocks to cyclical fluctuations.

Geometry effects on zonal flow dynamics and turbulent transport in optimized stellarators

Nuclear Fusion
Global gyrokinetic simulations find a strong suppression of ion temperature gradient (ITG) turbulence by zonal flows in stellarators optimized for neoclassical transport.

Anchored or Adrift? A Note on Measuring Inflation Expectations Anchoring

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We develop a behavioural model of inflation which contains an indicator that quantifies the expectations unanchoring risk over the business cycle. We estimate this model using US and Canadian inflation and output gap data. We find that during the post‐pandemic inflation surge, the macroeconomic data are compatible with non mean‐reverting ...

Effect of 4.6 GHz LHW on tungsten transport in NBI dominant H-mode plasma in EAST tokamak

Nuclear Fusion
Experimental observations in EAST tokamak have revealed a notable suppression of tungsten accumulation during the lower hybrid wave (LHW) injection in the neutral beam injection (NBI)-heated H-mode plasma.

Learning From 25 Years of Changes in Business Tax Policy

Public Budgeting &Finance, EarlyView.
Abstract This paper summarizes the significant changes to the taxation of business income in the United States over the last 25 years and how the resulting policy variation has helped inform research on business taxation. The survey of research on the topic covers investment incentives, international taxation, corporate financial policy, issues with ...

Isotope effects on transport characteristics of edge and core plasmas heated by neutral beam injection (NBI) in an inward shifted configuration at the Large Helical Device

Nuclear Fusion
Isotope effects have been investigated in Neutral Beam Injection (NBI) heated plasmas on the Large Helical Device with similar operational parameters between Hydrogen (H) and Deuterium (D) plasmas.

That's Not a Thing: Reification as a Tool for Ethical Critique

Philosophical Perspectives, EarlyView.
ABSTRACT Reification is a social pathology that occurs when we treat social relations as things independent of our collective agency. It is not simply a category mistake, nor is it an isolated error that any single individual can correct. Rather, reification involves a collective and systematic reflexivity deficit caused by the unjust, oppressive, or ...
