Significance The emerging field of gamified citizen science continually probes the fault line between human and artificial intelligence. A better understanding scientists’ search strategies may lead to cognitive insights provide inspiration for algorithmic improvements. Our project remotely engages both general public experts in real-time optimization an experimental laboratory setting. In this game data acquisition are designed as a social experiment aimed at extracting collective behavior...
Geothermal energy is a resource that has the potential for development in many countries around world. Despite its versatility and economic viability, this faces numerous obstacles hinder deployment capacity achieving similar market share as other renewable clean sources. Both technical non-technical barriers can be highly detrimental to implementation of geothermal projects. A social license operate (SLO) tool help energy. As new concept, SLO little developed business literature but still...
We demonstrate novel implementations of high-precision optical magnetometers which allow for spatially-selective and spatially-resolved in situ measurements using cold atomic clouds. These are realised by shaped dispersive probe beams combined with balanced homodyne detection. Two magnetometer sequences discussed: a vectorial magnetometer, yields sensitivities two orders magnitude better compared to previous realisation Larmor capable measuring absolute magnetic fields. characterise the...
We demonstrate a method to determine the position of single atoms in three-dimensional optical lattice. Atoms are sparsely loaded from far-off-resonant tweezer into few vertical planes cubic lattice positioned near high-resolution microscope objective. In realization experiment, we pin deep lattices and then acquire multiple fluorescence images with single-site resolution. The objective is translated between images, bringing different focus. applicability our assessed using simulated where...
One of the major challenges regarding energy transition is to create active support towards renewable installations on a local level. The CROWDTHERMAL project presents practical approaches for involving stakeholders in different measures order develop acceptable solutions. Based technical evidence and data from concrete case studies, shows ways how community funding can increase social acceptance geothermal installations. presented solutions are based alternative financial schemes studies...
We demonstrate how dispersive atom number measurements during evaporative cooling can be used for enhanced determination of the parameter dependence transition to a Bose-Einstein condensate (BEC).In this way shot-to-shot fluctuations in initial conditions are detected and information extracted per experimental realization is increased.We furthermore calibrate in-situ images from probing BEC with corresponding absorption time-of-flight.This allows point single by applying multiple...
We introduce a new experimental setup with biasing circuit and computer control for electrical power regulation under reversing polarity in Pt microwires dimensions of 1×10 μm2. The is controlled via data acquisition board. It amplifies signal from the drives current alternating through sample question. Time-to-failure investigations DC AC stress are performed. confirm that can improve life time at least by factor 103 compared to corresponding time-to-failure stress.
ANYONE OF A CERTAIN AGE who has even a passing interest in computers will remember the remarkable breakthrough that IBM made 1997 when its Deep Blue chess-playing computer defeated Garry Kasparov, then world chess champion. Computer scientists passed another such milestone March 2016, DeepMind (a subsidiary of Alphabet, Google's parent company) announced AlphaGo program had world-champion player Lee Sedol game Go, board vexed AI researchers for decades. Recently, DeepMind's algorithms have...
Remote control of experimental systems allows for improved collaboration between research groups as well unique remote educational opportunities accessible by students and citizen scientists. Here, we describe an experiment the production investigation ultracold quantum gases capable asynchronous multiple users. This is enabled a queuing system coupled to interface that can be modified suit user, e.g. gamified use general public or scripted expert. To demonstrate this, laboratory was opened...
When $50$ nm thick Pt microheaters of lateral dimensions $1\times10$ $\mu$m$^2$ are subjected to high electric power their resistance $R$ rises, as expected. Following an initial rise however there is a gradual decrement in while constant dissipation maintained. We find that this lowering accompanied by grain growth the polycrystalline thin film our heaters. This confirmed XRD measurements and SEM imaging. Similar size observed films oven-annealed at temperatures. Thus we argue maintaining...
<p>CROWDTHERMAL is an EU Horizon 2020 project, developing alternative funding schemes for geothermal energy. CROWDTHERMAL supports the European Green Deal aiming at reaching carbon neutrality by 2050. To reach this goal involvement of society needed. In 2017, renewable energy accounted 17.5% gross consumption, which only 3% were – despite its upsides and positive impact regarding decarbonization heating cooling in Europe. Geothermal green, available 24 hours a...
