70. xTMS: A Pulse Generator for Exploring Transcranial Magnetic Stimulation Therapies

Author

Ali, K, Wendt, K, Sorkhabi, MM, Benjaber, M, Denison, T, and Rogers, DJ

Abstract

A cascaded H-bridge based pulse generator for transcranial magnetic stimulation is introduced. The system demonstrates complete flexibility for producing different shape, duration, direction, and rate of repetition of stimulus pulses within its electrical limits, and can emulate all commercial and research systems available to-date in this application space. An offline model predictive control algorithm, used to generate pulses and sequences, shows superior performance compared to conventional carrier-based pulse width modulation. A fully functioning laboratory prototype delivers up to 1.5 kV, 6 kA pulses, and is ready to be used as a research tool for the exploration of transcranial magnetic stimulation therapies by leveraging the many degrees-of-freedom offered by the design.

89. Pedelec-Fahrer werden bei Unfällen schwerer verletzt als konventionelle Radfahrer

Author

Lefarth, T. L., Poos, H. P. A. M., Juhra, C., Wendt, K. W., and Pieske, O.

Abstract

Hintergrund: Seit Jahren nimmt die Nutzung von elektrisch unterstützten Fahrrädern (Pedelecs, im Volksmund „E-Bikes“) in Deutschland zu. Hierdurch steigt auch die Anzahl (schwer) verletzter und verstorbener Pedelec-Fahrer. Im klinischen Alltag entsteht der Verdacht, dass Pedelec-Fahrer bei Unfällen häufiger schwerer verletzt werden als konventionelle Fahrradfahrer. Fragestellung: Analyse der Morbidität und Mortalität durch Unfälle von Pedelec-Fahrern im Vergleich zu konventionellen Fahrradfahrern in einem überregionalen Traumazentrum im Traumanetzwerk Oldenburg-Ostfriesland. Material und Methoden: Prospektive Kohortenstudie mit Erhebung von Daten von 59 Pedelec-Fahrern und 164 konventionellen Fahrradfahrern nach Unfällen mit Vorstellung in der Notaufnahme und Klinik für Unfallchirurgie, Orthopädie und Sporttraumatologie des Evangelischen Krankenhauses Oldenburg in der Periode vom 01.03.2017 bis zum 01.03.2019. Ergebnisse: Das Durchschnittsalter von Pedelec-Fahrern und konventionellen Fahrradfahrern unterschied sich signifikant mit 62 bzw. 48 Jahren. Pedelec-Fahrer sind häufiger vorerkrankt als konventionelle Radfahrer und werden bei Unfällen signifikant schwerer verletzt. Hierbei liegt der durchschnittliche ISS bei 5,2 im Vergleich zu 3,4. Die Sterberate von Pedelec-Fahrern unterscheidet sich nicht von der konventioneller Radfahrer. Schlussfolgerung: Pedelec-Fahrer bilden im Vergleich zum durchschnittlichen Fahrradfahrer eine besondere Risikogruppe. Sie werden bei Unfällen signifikant schwerer verletzt als konventionelle Fahrradfahrer. Aufgrund der demografischen Entwicklung mit steigendem Durchschnittsalter und Multimorbidität von Verkehrsteilnehmern sowie der stetig wachsenden Verkaufszahlen von Pedelecs ist mit einer Zunahme schwerer Pedelec-Unfälle zu rechnen. Auf Pedelec-Nutzer gerichtete Maßnahmen zu Unfall- und Verletzungsprävention (wie z. B. Helm tragen, Pedelec-Kurse o. Ä.) sollten gefördert werden. In der Notfallmedizin sollten Pedelec-Nutzer besondere Aufmerksamkeit und aggressive Diagnostik erfahren. Niedrigschwellig sollte ein interdisziplinäres Initialassessment der Patienten erfolgen (Schockraummanagement).

90. Relative Comparison of Non-Invasive Brain Stimulation Methods for Modulating Deep Brain Targets

Abstract

This study models and investigates whether temporally interfering electric fields (TI EFs) could function as an effective non-invasive brain stimulation (NIBS) method for deep brain structure targeting in humans, relevant for psychiatric applications. Here, electric fields off- and on-target are modelled and compared with other common NIBS modalities (tACS, TMS). Additionally, local effects of the field strength are modelled on single-compartment neuronal models. While TI EFs are able to effectively reach deep brain targets, the ratio of off- to on-target stimulation remains high and comparable to other NIBS and may result in off-target neural blocks. Clinical Relevance— This study builds on earlier work and demonstrates some of the challenges -such as off-target conduction blocks- of applying TI EFs for targeting deep brain structures important in understanding the potential of treating neuropsychiatric conditions in the future.

Abstract

© 2020, The Author(s). Molecular spectroscopy offers opportunities for the exploration of the fundamental laws of nature and the search for new particle physics beyond the standard model1–4. Radioactive molecules—in which one or more of the atoms possesses a radioactive nucleus—can contain heavy and deformed nuclei, offering high sensitivity for investigating parity- and time-reversal-violation effects5,6. Radium monofluoride, RaF, is of particular interest because it is predicted to have an electronic structure appropriate for laser cooling6, thus paving the way for its use in high-precision spectroscopic studies. Furthermore, the effects of symmetry-violating nuclear moments are strongly enhanced5,7–9 in molecules containing octupole-deformed radium isotopes10,11. However, the study of RaF has been impeded by the lack of stable isotopes of radium. Here we present an experimental approach to studying short-lived radioactive molecules, which allows us to measure molecules with lifetimes of just tens of milliseconds. Energetically low-lying electronic states were measured for different isotopically pure RaF molecules using collinear resonance ionisation at the ISOLDE ion-beam facility at CERN. Our results provide evidence of the existence of a suitable laser-cooling scheme for these molecules and represent a key step towards high-precision studies in these systems. Our findings will enable further studies of short-lived radioactive molecules for fundamental physics research.
