Grid-friendly operation of a building cluster
No full textEnergy flexibility of buildings plays an important role on the way to the net zero emission target. Investigation of the energy flexibility of a building cluster requires detailed information on building load depending on load management signal, electricity generation, the local electrical grid and the transformer. The developed co-simulation environment allows detailed simulations with individual building load management signals and setpoints. Building load management uses day-ahead prices and CO2 profiles with an hourly low, mid and high level for each day which can be overridden by transformer priority management when stress at the transformer occurs. Using a cluster of eight single-family buildings it is shown that both building load management signals lead to slightly lower costs for the cluster compared to a case without signal. But the price load management results in higher and the CO2 load management in lower CO2-emissions. Thermal comfort does not change significantly. The transformer priority management is seldomly active, as only grid draw is considered. The transformer is mainly stressed by PV feed-in. The considered building cluster can be operated in a grid-friendly manner in the scope of the building load management. Transformer priority management effects are limited due to cluster size and configuration
Collaboration on school improvement under different educational accountability systems in two countries
No full textSchools must continuously improve their practices to address today’s societal challenges. To advance school improvement, educational accountability systems have been implemented in many parts of the world; they vary significantly in the levels of pressure they exert on schools. Given that school improvement is inherently a social and complex collaborative process, this paper delves deeper into how collaboration within school teams on improvement efforts varies across different accountability systems, considering social network data of school teams for the first time. Primary, key elements of accountability systems are analyzed theoretically to better understand the relationship between educational accountability systems and collaboration on school improvement. Taking an exploratory binational approach, the paper then compares a more bureaucratic and legal accountability system, operating as a high-stakes approach, in a school district in a city in California, USA, and a more professional accountability system, operating as a low-stakes approach, in a school community in a canton in the German-speaking part of Switzerland. The main focus of the comparative analyses is on key elements of the social network structure of staff members of elementary schools and central conditions of collaboration on school improvement, namely, trust relations and leadership. The findings provide initial evidence for a more positive relationship between collaboration on school improvement, social cohesion, and trust in a system that focuses on professional accountability than in a system that focuses on bureaucratic and legal accountability. There are no accountability-specific differences in the network position of leaders in this comparison, however. The findings suggest that the assumptions are worth pursuing further in future research

Synthesis of α‐Fluoroketones from Carboxylic Acids via Decarboxylation of Fluorinated Malonates
No full textα-Fluoroketones are versatile intermediates for the synthesis of fluorinated heterocycles and other fluorine-containing building blocks. We have recently disclosed a novel route to such an α-fluoroketone using the corresponding benzoic acid as a starting material. The reaction sequence started with the CDI-activation of the carboxylic acid and reaction with diethyl malonate, fluorination of the resulting acyl malonate with Selectfluor, and finally a double-decarboxylation to provide the desired α-fluoroketone in 73 % yield over three telescoped steps. We were interested in the generality of this approach to access α-fluoroketones from readily available carboxylic acids. In this article, we disclose the crucial modifications of the reaction conditions that were needed to make them broadly applicable to a diverse array of carboxylic acids. Under the optimized conditions, a wide range of α-fluoroketones were isolated in good to excellent yields and in high purity
Influence of statistical approaches on Probabilistic Sweet Spots computation in Deep Brain Stimulation for severe Essential Tremor
No full textDeep Brain Stimulation (DBS) is an established therapy for movement and neuropsychiatric disorders. Identifying brain regions (Probabilistic Sweet Spots, PSS) linked with the greatest symptom improvement is crucial for refining pre-operative targeting and post-operative programming. Probabilistic stimulation mapping is a powerful data-driven tool to delineate these regions. However, the chosen statistical methods can influence the identified PSS. A comprehensive evaluation of their impact is lacking in DBS research. The present study compares the PSS generated with four voxel-wise statistical approaches — t-test, Wilcoxon test, Linear Mixed Model, and Bayesian t-test — with the aim of assessing their influence on computed results on the same dataset. Intra-operative stimulation test data of 23 Essential Tremor (ET) patients was used to run patient-specific electric field simulations and to generate PSS in a group-specific anatomical template space. The PSS for the different statistical tests were first compared in terms of size and topography. Then, their correlation with clinical improvement was calculated in a leave-one-out cross-validation scheme and PSS consistency across datasets with different compositions was assessed. Our findings emphasize the impact of statistical test selection on both the anatomical location and volume of the extracted PSS, highlighting the importance of careful methodological choices in future DBS mapping studies. The Bayesian t-test and a voxel-wise application of nonparametric permutation testing, introduced for the first time in DBS research, showed promising results in identifying PSS representative of improvement and exhibited robustness to variations in the dataset

Co-Creating Sustainable Futures (CoFu). Nachhaltigkeitskultur an der FHNW gestalten (PgB swissuniversities, 2025-2026)
No full text«CoCreating Sustainable Futures» (CoFu) ist ein von swissuniversities mitfinanziertes PgB-Projekt, das darauf abzielt, die Nachhaltigkeitskultur der FHNW zu stärken. Im Sinne des «Whole Institution Approach» sind alle Angehörigen der FHNW eingeladen, sich an der Entwicklung und Umsetzung von institutionsbezogenen Nachhaltigkeitsprojekten zu beteiligen und so die strategischen Zukunftsfelder New Work, Zero Emission und Future Health nach innen zu tragen.
In ko-kreativen Prozessen leistet CoFu einen Beitrag zu einer zukunftsweisenden, gesamtinstitutionellen Nachhaltigkeitskultur und geht hierfür kulturelle wie strukturelle Veränderungsprozesse aktiv an. Damit folgt CoFu der Vision der FHNW, Zukünfte zu gestalten – indem sie in ihren strategischen Zukunftsfeldern nicht nur forscht und lehrt, sondern diese als Bildungsorganisation auch selbst vorlebt und verwirklicht. Das Bild eines «Zukunftstrichters» erinnert einerseits an ein plurales Verständnis von Zukünften und veranschaulicht andererseits den ko-kreativen Prozess, in dem Ideen vernetzt, entwickelt und umgesetzt werden
