Tokamak edge-SOL turbulence in H-mode conditions simulated with a global, electromagnetic, transcollisional drift-fluid model

Nuclear Fusion
The design of commercially feasible magnetic confinement fusion reactors strongly relies on the reduced turbulent transport in the plasma edge during operation in the high confinement mode (H-mode).

Antimicrobial Use in Livestock: The Economic Cost of Action or Inaction

Journal of Agricultural Economics, EarlyView.
ABSTRACT This paper quantifies the economy‐wide consequences of two independent global stress‐tests in livestock production. The first assesses the effects of phasing out antimicrobial growth promoters (AGPs), and the second evaluates the long‐term impacts of antimicrobial resistance (AMR) progression.

Neoclassical Transport Analysis around An m/n = 1/1 Magnetic Island

, 2007
"In order to analyze neoclassical transport phenomena in/around a magnetic field configuration with an m/n = 1/1 magnetic island, where m is a poloidal mode number and n a toroidal mode number, we are developing a new neoclassical transport simulation ...

MONKES: a fast neoclassical code for the evaluation of monoenergetic transport coefficients in stellarator plasmas

Nuclear Fusion
MONKES is a new neoclassical code for the evaluation of monoenergetic transport coefficients in stellarators. By means of a convergence study and benchmarks with other codes, it is shown that MONKES is accurate and efficient.

Efficiency, Shadow Pricing and Regime Switching in Multi‐Ware Technologies: Evidence From Regulated Livestock Farms

Journal of Agricultural Economics, EarlyView.
ABSTRACT We develop a framework for regulated production systems where output generation and pollution abatement impose competing technological demands. Using a multi‐ware technology, we model the production set as the intersection of two input requirement frontiers, one for production and one for abatement, each reflecting distinct trade‐offs.

Neoclassical electron and ion transport in toroidally rotating plasmas

, 1997
Neoclassical transport processes of electrons and ions are investigated in detail for toroidally rotating axisymmetric plasmas with large flow velocities on the order of the ion thermal speed.

How Can Accountants Enhance (or Save) Natural and Cultural Capital Valuation? Engaging Academics: A Collaboration with CPA Canada and the Canadian Commission for UNESCO*

Accounting Perspectives, Volume 24, Issue 1, Page 21-46, March 2025.
ABSTRACT Accountants should engage more with natural and cultural capital accounting to make tools more accessible and to ensure critical information is provided to decision‐makers. While ecological economists have continued to innovate and design tools, corporate‐level accounting has seemingly lagged behind.

Turbulence-reduced high-performance scenarios in Wendelstein 7-X

Nuclear Fusion
In the Wendelstein 7-X (W7-X) stellarator, turbulence is the dominant transport mechanism in most discharges. This leads to a ‘clamping’ of ion temperature over a wide range of heating power, predominantly flat density profiles where hollow profiles ...

Does Continuous Disclosure Improve Investment Efficiency? Evidence from a Unique Regulatory Setting

Abacus, EarlyView.
We examine the association between continuous disclosure and investment efficiency within the context of Australia's unique regulatory setting for continuous disclosure. Based on 8,527 firm‐year observations, we find that continuous disclosure is positively associated with investment efficiency and helps to mitigate both over‐investment and under ...
