THE URBANOLOGISTS COME TO TOWN: Professional Life and Work in the Urban Solutions Industry

International Journal of Urban and Regional Research, EarlyView.
Abstract This article charts the upsurge of an eclectic global community of professionals new to the field of urban policy and governance, animated by playful and celebratory attitudes towards cities and urbanization: the urbanologists. It contributes to debates in critical urban theory and critical ethnographies of technology to problematize ...

Controlling impurity transport in 5D gyrokinetic simulations using a transport barrier

Nuclear Fusion
The effects of transport barriers on impurity transport, specifically helium (He) and tungsten (W), are investigated using the global, flux-driven, full-F, 5D gyrokinetic code GYSELA.

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

Insect Science, EarlyView.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...

CRISPR/Cas9‐based white pupae mutant lines in Bactrocera spp. for sterile insect technique applications

Insect Science, EarlyView.
Bactrocera fruit flies are significant horticultural pests that cause major economic losses. A “neoclassical approach” incorporating genome editing via CRISPR/Cas9 to develop genetic sexing strains (GSS) could render the sterile insect technique (SIT) against these pests more efficient and cost‐effective.

Reduction of neoclassical bulk-ion transport to avoid helium-ash retention in stellarator reactors

Nuclear Fusion
The reduction of neoclassical energy transport in stellarators has traditionally focussed on optimizing magnetic fields for small values of ‘effective helical ripple’ — $\epsilon_\mathrm{eff}$ , the geometric factor associated with electron $1/\nu ...

Neoclassical development of genetic sexing strains for insect pest and disease vector control

Insect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

Neoclassical transport of toroidal momentum in tokamaks

Physical Review Letters, 1990
La presence d'une concentration moderee (∼10%) d'ions de basses energies en exces par rapport a la distribution maxwellienne provoque un changement dramatique dans la prediction neoclassique du transport de la quantite de mouvement, conduisant a un accord en magnitude avec l ...

Exploration of the parameter space of piecewise omnigenous stellarator magnetic fields

Nuclear Fusion
Piecewise omnigenous fields are stellarator magnetic fields that are optimized with respect to radial neoclassical transport thanks to a second adiabatic invariant that is piecewisely constant on the flux-surface.

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.

Anisotropic distribution of alpha particles in a tokamak reactor

Nuclear Fusion
We carried out systematic study of neoclassical equilibrium distribution of α particles born from deuterium–tritium nuclear fusion in a tokamak reactor. The distribution in the phase space is visualized in various 2D planes. We studied a previously known
