There is significant interest from the medical andneuroscience communities for studying the behavior of zebrafishlarvae, particularly in the context of drug testing. In this paper, wepropose a method for analyzing the behavior of zebrafish larvaein a high-throughput system using automatic image analysis.Specifically, algorithms for estimating the poses of the larvae invideo recordings are presente

Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr

Vi betalar för tjänster som Facebook och Google genom att dessa företag får reda på mycket om oss. Men det oerhört svårt att se hur din data används och följa vart den tar vägen. Det krävs mer öppenhet, skriver experten Stefan Larsson.

I kärnan av den digitala ekonomin finns idag användning av individrelaterad information, ofta reglerad i termer av personuppgifter. Som konsument är det dessvärre allt svårare att bedöma när den samlas in, hur den används och vilka aktörer som hanterar den över tid, vilket riskerar att undergräva den tillit som ofta är en förutsättning för en fungerade digital marknad. Denna policy brief använder

Externa elektriska fält som appliceras på biologiska material interagerar direkt med fria elektriska laddningar som elektroner och joner samt jongrupper i större molekyler. De interagerar också med dipoler såsom vatten och inducerar dipoler i molekyler med polariserbara grupper. Cellmembranerna verkar vara det kritiska målet för interaktion som orsakar intra-molekylära övergångar och intermolekylä

In 2017, the Swedish government published an official report entitled "Att ta emot människor på flykt: Sverige hösten 2015." The report describes how Swedish state agencies, municipalities, and civil society conceptualized and managed the refugee crisis of 2015. This chapter spells out the official public theories expressed in this report and in doing so unfolds two key findings. First, the govern

This thesis is on information dynamics modeled using *dynamic epistemic logic* (DEL). It takes the simple perspective of identifying models with maps, which under a suitable topology may be analyzed as *topological dynamical systems*. It is composed of an introduction and six papers. The introduction situates DEL in the field of formal epistemology, exemplifies its use and summarizes the main cont

The aim of this study is to increase our understanding of the attitudes towards the scientific search for extraterrestrial life among high school and university students in Sweden. The most important results of the analysis are that: (a) the great majority of students believe that extraterrestrial life exists; (b) most students regard searching for extraterrestrial life to be quite important or ve

Hintikka’s "Knowledge and Belief" from 1962 is considered the seminal treatise on epistemic logic. It provides the nuts and bolts of what is now a flourishing paradigm of significance to philosophy, economics, mathematics and theoretical computer science—in theory as well as practice. And in theory and for practice epistemic logic has been extensively articulated, refined and developed especially

To mitigate dangerous climate change, a transition to a new and sustainable energy system is needed. In this system, solar energy will need to be a key player. Prices of electricity made from solar cells have declined rapidly over the recent decades, making solar energy competitive in more markets. However, further price reductions and new innovations are needed for solar cell technology to fulfil

Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor tem- perature. However, this control principle cannot take into account heat gains or losses caused by tenants, electrical appliances, the sun, air leakage, etc., which may result in uneven indoor Indoor temperatures in apartment blocks are often indirectly controlled by the outdoor temperature using a feedforward control loop, in which the radiator supply temperature is a function of the outdoor temperature.
