Durchführbarkeit der Trainingsprogression und Trainingssteuerung in einem digital und einem analog vermittelten Übungsprogramm für geriatrische Patient*innen

Natalie Hölzer, Martin Bongartz, R. Leonhardt, Sebastian Schölch et autres

Einleitung Um ein Training effektiv zu gestalten, ist eine wirksame Progression der Trainingsintensität notwendig. Dieses Prinzip der Trainingswissenschaft gilt auch für ältere Menschen, jedoch gibt es bisher kaum Untersuchungen zur Durchführbarkeit von Trainingsprogression und -steuerung in dieser Zielgruppe. Im Rahmen der dreiarmigen …

Einsatz einer eHealth-Applikation zur nachhaltigen Sicherung von Therapieerfolgen in der poststationären Geriatrischen Rehabilitation – Erfahrungen aus dem GeRas-Projekt

R. Leonhardt, Leonard Maier, Patrick Roigk, Bernd Abel et autres

Einleitung Das Risiko eines Verlusts von körperlicher Leistungsfähigkeit und Mobilität nach stationärer Entlassung ist für geriatrische Patient*innen hoch. Das G-BA-geförderte Projekt „Geriatrische Rehabilitationserfolge nachhaltig sichern“ (GeRas) möchte die poststationäre Versorgung geriatrischer Rehabilitationspatient*innen optimieren und durch ein mehrdimensionales, sektorenübergreifendes Nachsorgeprogramm eine Versorgungslücke schließen …

Phase-shifted Bell states

J. J. Joshua Davis, Carey L. Jackman, R. Leonhardt, Paul J. Werbos et autres

Inspired by previous studies and pioneers of the field, we present new results on an extensive Einstein, Podolsky, and Rosen (EPR)–Bell experiment using photons generated by parametric down-conversion, where one of the photons is deliberately phase-shifted. Our experiments show some surprising results …

Microresonator Frequency Reference for Terahertz Precision Sensing and Metrology

Rishabh Gandhi, R. Leonhardt, Dominik Walter Vogt

Highly sensitive terahertz (THz) sensors for a myriad of applications are rapidly evolving. A widespread sensor concept is based on the detection of minute resonance frequency shifts due to a targeted specimen in the sensors environment. Therefore, high resolution continuous wave (CW) …

THz frequency reference for precision metrology

Rishabh Gandhi, R. Leonhardt, Dominik Walter Vogt

We demonstrate a terahertz (THz) frequency reference for precision metrology, by utilising the inherently well- defined resonance frequencies of ultra-high quality (Q) THz microresonators. In a proof-of-concept experiment, we demonstrate the accurate and repeated detection of minute resonance frequency shifts of less …

Ultrahigh-Q terahertz Disc Microresonator With Sub-Wavelength Thickness

Dominik Walter Vogt, Angus Harvey Jones, Thomas Alan Haase, R. Leonhardt

We report on a Terahertz (THz) silicon disc microresonator with a quality factor (Q-factor) in excess of 120,000 at 0.6 THz. The ultra-high Q-factor is enabled by thinning the disc to a fraction of the free-space wavelength, thus minimising the impact of …

Parts-per-million water vapor sensing using an ultrahigh-Q THz disc microresonator

Dominik Walter Vogt, Angus Harvey Jones, R. Leonhardt

We report on the first demonstration of a THz gas spectrometer using a sub-wavelength thick ultrahigh-Q THz disc microresonator. Leveraging the microresonator's ultrahigh quality factor in excess of 120,000 and the intrinsically large evanescent field, allows for the implementation of a very …

Terahertz Gas-Phase Spectroscopy Using a Sub-Wavelength Thick Ultrahigh-Q Microresonator

Dominik Walter Vogt, Angus Harvey Jones, R. Leonhardt

The terahertz spectrum provides tremendous opportunities for broadband gas-phase spectroscopy, as numerous molecules exhibit strong fundamental resonances in the THz frequency range. However, cutting-edge THz gas-phase spectrometer require cumbersome multi-pass gas cells to reach sufficient sensitivity for trace level gas detection. Here, …

Subwavelength thick ultrahigh-Q terahertz disc microresonators

Dominik Walter Vogt, Angus Harvey Jones, Thomas Alan Haase, R. Leonhardt

Artificial structures that exhibit narrow resonance features are key to a myriad of scientific advances and technologies. In particular, exploration of the terahertz (THz) spectrum—the final frontier of the electromagnetic spectrum—would greatly benefit from high-quality resonant structures. Here we present a new …
