The quasi-continuous exhaust regime in ASDEX Upgrade and JET

Faitsch, M. · Dunne, M. · Lerche, E. + 5 authors

2025Publisher: ElsevierRepository: idUS — Universidad de Sevilla

The quasi-continuous exhaust (QCE) regime is a type-I ELM-free high confinement regime obtained at high plasma shaping and high separatrix density. A comparison with various ELM-free regimes in the literature is presented together with potential physics models for accessing the…

Design, validation and psychometric properties of a questionnaire to assess intrapreneurial behaviours in sports organisations

Lara Bocanegra, Alejandro · Bohórquez Gómez-Millán, María Rocío · García Fernández, Jerónimo + 2 authors

2025Publisher: SpringerRepository: idUS — Universidad de Sevilla

Intrapreneurs in sports organisations can detect early signs of new opportunities and threats and introduce early changes to adapt to the constant changes in the sports sector. In addition, intrapreneurs are considered a fundamental pillar in the growth and development of…

Active Network Management via grid-friendly electromobility control for curtailment minimization

Čičić, Mladen · Vivas Venegas, Carlos · Canudas-de-Wit, Carlos + 1 author

2025Publisher: ElsevierRepository: idUS — Universidad de Sevilla

We propose an integrated power and transportation system control framework, combining the power grid model with a macroscopic electromobility model including charging stations under V2G operation. In this framework, the electrical vehicles (EVs) act as energy storage, but also…

PriSpecTemp report: literature study on experimental line intensity of CO, CO2 and O2

Lüttschwager, Alexandra · Berezkin, Kirill · Li, Gang + 5 authors

2025Publisher: Physikalisch-Technische Bundesanstalt (PTB)Repository: oar.ptb.de

This report is an overview of the existing literature sources for the atmospheric “sensor" molecules (CO, CO2, O2). Existing accurate measurements of the line intensity in different frequency ranges (molecular bands), suitable for both highly accurate ab initio calculations…

Traceable low activity concentration calibration of radon detectors for climate change observation networks

Röttger, Stefan · Röttger, Annette · Mertes, Florian + 4 authors

2025Publisher: Physikalisch-Technische Bundesanstalt (PTB)Repository: oar.ptb.de

Radon gas is the largest source of public expo-sure to naturally occurring radioactivity, and concentration maps based on atmospheric measurements aid developers in complying with EU Safety Standard Regulations. But radon can also be used as a tracer to evaluate dispersal models…

Phantom power test setup for accuracy measurements of high power DC charging stations

Blaz, Michael · Leicht, Christoph · Mohns, Enrico + 1 author

2025Publisher: Physikalisch-Technische Bundesanstalt (PTB)Repository: oar.ptb.de

This paper describes a test setup for determining the accuracy of energy measurement of high power DC charging stations. To avoid the need for a controllable high power load to set up the test points, a new approach using phantom power is described. The suitability of the test…

Radon sensor networks for large buildings: balancing the trade-off between energy efficiency and health

Röttger, Stefan · Nötzel, Ralf · Honig, Anja + 2 authors

2025Publisher: Physikalisch-Technische Bundesanstalt (PTB)Repository: oar.ptb.de

Radon 222 is a radioactive noble gas that is formed in the decay of the primordial 238U decay chain, with an average abundance of 3 parts per million (3 g ⋅ t-1) in the earth's crust. Since radon is the only noble gas in the decay chain, it has with its half live T12 = 3.8232(8)…

Virtual body continuity during action observation affects motor cortical excitability

Matamala Gómez, Marta · Frisco, Francesca · Guidali, Giacomo + 4 authors

2025Publisher: SpringerRepository: UPCommons — Universitat Politècnica de Catalunya

Body ownership, the sense that the body belongs to oneself, can be altered by inducing body manipulations in Virtual Reality, such as by increasing the visual discontinuity between the avatar’s hand and body. Body representation manipulations can also influence motor cortex…
