Digital Transformation in Work Integration Social Enterprises: Leadership Strategies and the Role of Internal Stakeholders

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Digital transformation is increasingly reshaping how social enterprises organize work, engage stakeholders, and pursue social value. While prior research has examined digitalization in hybrid organizations, limited attention has been paid to how responsibility for inclusive digital transformation is enacted internally.

Regulation compliant AI for fusion: explainable image-based feedback control of divertor detachment in DIII-D tokamak

Nuclear Fusion
While artificial intelligence (AI) has been promising for fusion control, its inherent black-box nature will make compliant implementation in regulatory environments a challenge.

Understanding Divertor Detachment through CRETIN Modeling - a Work in Progress [PDF]

, 1998
From numerous studies aimed at reducing the divertor target plate incident heat flux or understanding divertor detachment, an abundance of evidence supporting the importance of atomic processes in tokamak plasmas now exists.

An Estimation of the Heat Load Distribution on the Divertor Target Using the CSD Model

Contributions to Plasma Physics, EarlyView.
ABSTRACT Handling the heat load on the divertor target is a critical issue in the design of fusion reactors. Estimating the heat load, supported by computationally efficient simulations with varying design parameters, provides valuable input to high‐level design discussions and the development of design guidelines.

Coupling Fluid Neutrals to Gyrokinetic Plasma Dynamics for Edge and SOL Turbulence Simulations

Contributions to Plasma Physics, EarlyView.
ABSTRACT Accurate modeling of turbulent transport in magnetic confinement fusion devices requires extending first‐principles gyrokinetic simulations from the core to the edge and scrape‐off layer (SOL), where additional physics—particularly plasma–neutrals interactions—must be included.

Current understanding of divertor detachment: Experiments and modelling

Journal of Nuclear Materials, 2009
A qualitative as well as quantitative evaluation of experimentally observed plasma parameters in the detached regime proves to be difficult for several tokamaks. A series of ohmic discharges have been performed in ASDEX Upgrade and DIII-D at similar as possible plasma parameters and at different line averaged densities, {bar n}{sub e}. The experimental

Heat Load Mitigation Studies in the W7‐X Stellarator Experiment

Contributions to Plasma Physics, EarlyView.
ABSTRACT During the experiments at the stellarator Wendelstein 7‐X (W7‐X) with fully water‐cooled plasma‐facing components (PFC), including carbon‐fiber composite (CFC) divertor targets with a thermal load capability of 10 MW/m2, high performance was achieved.

First SOLPS‐ITER Simulation Study of Japanese DEMO on Leakage of Seeded Ar Impurity

Contributions to Plasma Physics, EarlyView.
ABSTRACT For JA DEMO, one of the grand challenges is efficiently handling the extreme power loads onto plasma‐facing components, particularly the divertor targets. Impurity seeding is an essential strategy for increasing the radiation losses and thereby reducing the heat load on the targets.

A Socially Assistive Robot for Outpatient Eating Disorder Waiting‐List Support: A Mixed‐Methods Feasibility Randomised Controlled Trial

European Eating Disorders Review, EarlyView.
ABSTRACT Objective This feasibility randomised controlled trial (RCT) evaluated Purrble, a socially assistive robot for emotion regulation, as a low‐intensity adjunct during waitlist periods in adult eating disorder services. Method Adults waiting for outpatient eating disorder treatment were randomised to four weeks of Purrble use or waitlist‐as‐usual.
