Prototypische Realisierung einer mobilen Anwendung für die simultane Aktivitätsmessung mit Schrittzähler und EMG-Sensoren

Die Messung der körperlichen Aktivität ist Bestandteil diverser wissenschaftlicher Disziplinen, wie beispielsweise den Sport- und Gesundheitswissenschaften, wo die Erfassung von Aktivität zur Prävention und Rehabilitation eingesetzt wird. Diesbezüglich entwickelten sich im Laufe der Zeit eine Reihe von Technologien zur Erfassung unterschiedlicher Formen von körperlicher Aktivität. Die Elektromyographie (EMG) ermöglicht die spezifische digitale Erfassung der elektrischen Muskelaktivität von Lebewesen. Mit sogenannten Schrittzählern wird heutzutage die allgemeine körperliche Aktivität von Personen aufgezeichnet. In der vorliegenden Bachelor-Thesis wurden die beiden genannten Technologien in einer mobilen Software miteinander kombiniert, um so den Aktivitätsverlauf zwischen Schritten und Gesten digital abzubilden und zu analysieren. Die Erkenntnisse dieser Arbeit fliessen letztlich die Entwicklung einer Software ein, welche im Umfeld der Ergotherapie für die Analyse von Bewegungsabläufen verwendet wird

Geometry of Entanglement Sudden Death: Explicit Examples

In open quantum systems, entanglement can vanish faster than coherence. This phenomenon is usually called sudden death of entanglement. In [M. O. Terra Cunha, New J. Phys. 9, 237 (2007)] a geometrical explanation was offered and a classification of all possible scenarios was given. Some classes were exemplified, but it was still an open question whether there were examples for the other ones. This was solved in [R.C. Drumond and M.O. Terra Cunha, arXiv:0809.4445v1]. Here we briefly review the problem, state our results in a precise way, discuss the generality of the approach, and add some speculative desirable generalizations.Comment: Contribution written to the Procceedings of 5th Vaxjo Conference on Foundations of Probability and Physic

Gastfamilien für ukrainische Geflüchtete Kurzbericht zur überregionalen Befragung von Gastfamilien zwischen Oktober und Dezember 2022

Nach Ausbruch des russischen Angriffskrieges in der Ukraine und der dadurch ausgelösten Fluchtbewegung zeigte die Bevölkerung in der Schweiz eine riesige Solidarität. Bis zu 30'000 Familien und Einzelpersonen waren damals sofort bereit, ukrainische Geflüchtete bei sich privat aufzunehmen. Bis Ende 2022 haben rund 75’000 Menschen aus der Ukraine in der Schweiz Schutz beantragt,1 35 Prozent von ihnen sind bei Gastfamilien untergebracht. Das sind knapp 25’000 Personen, die sonst zusätzlich in staatlichen Unterkünften hätten einquartiert werden müssen. Im Auftrag des Staatssekretariats für Migration (SEM) konnte die Schweizerische Flüchtlingshilfe ( SFH) bis Ende 2022 rund 5'700 Geflüchtete in 2'500 Gastfamilien vermitteln. Erstmals in der jüngeren Geschichte bildete die Privatunterbringung ein tragendes Element der offiziellen Aufnahmepolitik von Geflüchteten in der Schweiz und half mit, eine Überlastung des Asylsystems zu verhindern. Doch die Gastfamilien bieten den Geflüchteten viel mehr als ein Dach über dem Kopf : Sie unterstützen die Integration der Geflüchteten auf unterschiedlichste Weise. Der vorliegende Kurzbericht gibt einen Überblick über die Vielfältigkeit der Gastfamilien und ihrer Unterstüt- zung für die geflüchteten Menschen aus der Ukraine

Pressure Dependence of the Irreversibility Line in Bi2_{2}Sr2_{2}CaCu2_{2}O8+δ_{8+\delta}:Role of Anisotropy in Flux-Line Formation

One of the important problems of high-temperature superconductivity is to understand and ultimately to control fluxoid motion. We present the results of a new technique for measuring the pressure dependence of the transition to superconductivity in a diamond anvil cell. By measuring the third harmonic of the {\it ac} susceptibility, we determine the onset of irreversible flux motion. This enables us to study the effects of pressure on flux motion. The application of pressure changes interplanar spacing, and hence the interplanar coupling, without significantly disturbing the intraplanar superconductivity. Thus we are able to separate the effects of coupling from other properties that might affect the flux motion. Our results directly show the relationship between lattice spacing, effective- mass anisotropy, and the irreversibility line in Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+\delta}$. Our results also demonstrate that an application of 2.5 GPa pressure causes a dramatic increase in interplanar coupling.Comment: 4 pages, 4 figure

B(H) Constitutive Relations Near H_c1 in Disordered Superconductors

We provide a self-contained account of the B vs. H constitutive relation near H_c1 in Type II superconductors with various types of quenched random disorder. The traditional Abrikosov result B ~ [ln (H - H_c1)]^{-2}, valid in the absence of disorder and thermal fluctuations, changes significantly in the presence of disorder. Moreover, the constitutive relations will depend strongly on the type of disorder. In the presence of point disorder, B ~ (H - H_c1)^{3/2} in three-dimensional (thick) superconductors, as shown by Nattermann and Lipowsky. In two-dimensional (thin film) superconductors with point disorder, B ~ (H - H_c1). In the presence of parallel columnar disorder, we find that B ~ exp[-C / (H - H_c1)] in three dimensions, while B ~ exp[-K / (H - H_c1)^{1/2}] in two dimensions. In the presence of nearly isotropically splayed disorder, we find that B ~ (H - H_c1)^{3/2} in both two and three dimensions.Comment: 37 pages, 12 figures included in text; submitted to Physica

Changes in land use and management led to a decline in Eastern Europe’s terrestrial carbon sink

Land-based mitigation is essential in reducing net carbon emissions. Yet, the attribution of carbon fluxes remains highly uncertain, in particular for the forest-rich region of Eastern Europe (incl. Western Russia). Here we integrate various data sources to show that Eastern Europe accounted for an above-ground biomass carbon sink of ~0.41 gigatons of carbon per year over the period 2010–2019, that is 78% of the entire European carbon sink. We find that this carbon sink is declining, mainly driven by changes in land use and land management, but also by increasing natural disturbances. Based on a random forest model, we show that land use and management changes are main drivers of the declining carbon sink in Eastern Europe, although soil moisture variability is also important. Specifically, the saturation effect of tree regrowth in abandoned agricultural areas, combined with increasing wood harvest removals, particularly in European Russia, contributed to the decrease in the Eastern European carbon sink

On the use of Earth Observation to support estimates of national greenhouse gas emissions and sinks for the Global stocktake process: lessons learned from ESA-CCI RECCAP2

The Global Stocktake (GST), implemented by the Paris Agreement, requires rapid developments in the capabilities to quantify annual greenhouse gas (GHG) emissions and removals consistently from the global to the national scale and improvements to national GHG inventories. In particular, new capabilities are needed for accurate attribution of sources and sinks and their trends to natural and anthropogenic processes. On the one hand, this is still a major challenge as national GHG inventories follow globally harmonized methodologies based on the guidelines established by the Intergovernmental Panel on Climate Change, but these can be implemented differently for individual countries. Moreover, in many countries the capability to systematically produce detailed and annually updated GHG inventories is still lacking. On the other hand, spatially-explicit datasets quantifying sources and sinks of carbon dioxide, methane and nitrous oxide emissions from Earth Observations (EO) are still limited by many sources of uncertainty. While national GHG inventories follow diverse methodologies depending on the availability of activity data in the different countries, the proposed comparison with EO-based estimates can help improve our understanding of the comparability of the estimates published by the different countries. Indeed, EO networks and satellite platforms have seen a massive expansion in the past decade, now covering a wide range of essential climate variables and offering high potential to improve the quantification of global and regional GHG budgets and advance process understanding. Yet, there is no EO data that quantifies greenhouse gas fluxes directly, rather there are observations of variables or proxies that can be transformed into fluxes using models. Here, we report results and lessons from the ESA-CCI RECCAP2 project, whose goal was to engage with National Inventory Agencies to improve understanding about the methods used by each community to estimate sources and sinks of GHGs and to evaluate the potential for satellite and in-situ EO to improve national GHG estimates. Based on this dialogue and recent studies, we discuss the potential of EO approaches to provide estimates of GHG budgets that can be compared with those of national GHG inventories. We outline a roadmap for implementation of an EO carbon-monitoring program that can contribute to the Paris Agreement
