Accounting for the Evolution of China's Production and Trade Patterns

International Economic Review, EarlyView.
ABSTRACT We study the evolution of China's production and trade patterns during its integration into the global economy. Using firm‐level microdata, we document how production and exports shifted across industries and within industries across firms.

Conceptualising post‐growth to advance corporate sustainability research: A comparative literature review

International Journal of Management Reviews, EarlyView.
Abstract This comparative literature review explores how an expanding body of interdisciplinary post‐growth literature aligns, extends or challenges ecocentric Corporate Sustainability (eCS) research in management (i.e., rooted in systems thinking, emphasising planetary boundaries, ecological limits and embeddedness).

ESTIMATION OF RADIATION LOSS FROM STELLARATORS USING NEOCLASSICAL TRANSPORT THEORY [PDF]

Journal of Sciences, Islamic Republic of Iran, 1993
The radiation power loss from a magnetically confined plasma in a stellarator has been calculated using neoclassical particle and energy fluxes in an energy balance equation. We could obtain a power loss of about 34% of the total input power by numerical

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.

Central Bank Digital Currency with Collateral‐Constrained Banks

Journal of Money, Credit and Banking, EarlyView.
Abstract We analyze risks to bank intermediation following the introduction of a central bank digital currency (CBDC) competing with commercial bank deposits as households' source of liquidity. We revisit the equivalence of payment systems result, introducing a collateral constraint on banks' borrowing from the central bank.

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 Capital–Labour–State Dynamics of Herbicide Adoption in Rainfed India

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper engages debates around the capital–labour–state dynamics of agrarian transitions to address the oft‐studied but still little‐understood question of why farmers adopt herbicides when they do. Over the last several years, smallholder farmers in India have begun using the herbicide bispyribac sodium at breakneck speeds, particularly in

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 ...
