Simultaneous ground-state cooling of two mechanical modes of a levitated nanoparticle
(2022)arXivThe quantum ground state of a massive mechanical system is a steppingstone for investigating macroscopic quantum states and building high fidelity sensors. With the recent achievement of ground-state cooling of a single motional mode, levitated nanoparticles have entered the quantum domain. To overcome detrimental cross-coupling and decoherence effects, quantum control needs to be expanded to more system dimensions, but the effect of a ...Working Paper -
The Amazon in motion: Changing politics, development strategies, peoples, landscapes, and livelihoods
(2021)Amazon Assessment Report 2021, Part IIThis chapter reviews the often-invisible, powerful processes that drive social and ecological change in the Amazon, and the diverse peoples who inhabit its landscapes. It explores the large-scale development ideologies of modernization, and the policy tools that were deployed to carry them out. Outlining general periods of macro policy shifts, it shows the evolution of the framework for today’s complex interactions between large-scale ...Report -
Fully Onboard SLAM for Distributed Mapping with a Swarm of Nano-Drones
(2023)arXivThe use of Unmanned Aerial Vehicles (UAVs) is rapidly increasing in applications ranging from surveillance and first-aid missions to industrial automation involving cooperation with other machines or humans. To maximize area coverage and reduce mission latency, swarms of collaborating drones have become a significant research direction. However, this approach requires open challenges in positioning, mapping, and communications to be ...Working Paper -
Robust Feature Selection for Continuous BP Estimation in Multiple Populations: Towards Cuffless Ambulatory BP Monitoring
(2023)TechRxivCurrent blood pressure (BP) estimation methods have not achieved an accurate and adaptable approach for application in populations at risk of cardiovascular disease, with generally limited sample sizes. Here, we introduce an algorithm for BP estimation solely reliant on photoplethysmography (PPG) signals and demographic features. Our approach automatically obtains signal features and employs the Markov Blanket (MB) feature selection to ...Working Paper -
A Counterfactual Safety Margin Perspective on the Scoring of Autonomous Vehicles' Riskiness
(2023)arXivAutonomous Vehicles (AVs) promise a range of societal advantages, including broader access to mobility, reduced road accidents, and enhanced transportation efficiency. However, evaluating the risks linked to AVs is complex due to limited historical data and the swift progression of technology. This paper presents a data-driven framework for assessing the risk of different AVs' behaviors in various operational design domains (ODDs), based ...Working Paper -
Delaying Decisions and Reservation Costs
(2023)arXivWe study the Feedback Vertex Set and the Vertex Cover problem in a natural variant of the classical online model that allows for delayed decisions and reservations. Both problems can be characterized by an obstruction set of subgraphs that the online graph needs to avoid. In the case of the Vertex Cover problem, the obstruction set consists of an edge (i.e., the graph of two adjacent vertices), while for the Feedback Vertex Set problem, ...Working Paper -
MOBIS-COVID19/01
(2020)Arbeitsberichte Verkehrs- und RaumplanungThis series of working papers presents the ongoing analysis of the mobility behaviour in Switzerland during the period of special measures to combat the Corona virus. A sample of over 1200 participants was recruited from a previous GPS-based mobility study, MOBIS. A 4 week baseline period is therefore available for each participant from the second half of 2019, as well as socio-economic variables. Mobility indicators considered include ...Report -
MOBIS-COVID19/14
(2020)Arbeitsberichte Verkehrs- und RaumplanungOn March 16, 2020, 3700 participants who completed the MOBIS study between September 2019 and January 2020 were invited to reinstall the GPS Logger and Travel Diary App ‘Catch-My-Day’, developed by MotionTag, to record their mobility behaviour during the period of special measures implemented to control the spread of the Corona Virus. The first 4 weeks of mobility data from the original MOBIS Study is taken for each participant as a ...Report -
