In this paper a multimodal optical-resolution photoacoustic and fluorescence microscope in frequency domain is presented. Photoacoustic waves and modulated fluorescence are generated in chromophores by using a modulated diode laser. The photoacoustic waves, recorded with a hydrophone, and the fluorescence signals, acquired with an avalanche photodiode, are simultaneously measured using a lock-in t
In both economic and evolutionary theories of games, two general classes of evolution can be identified: dynamics based on myopic optimization and dynamics based on imitations or replications. The collective behavior of structured populations governed by these dynamics can vary significantly. Particularly in social dilemmas, myopic optimizations typically lead to Nash equilibrium payoffs that are
Digital holography (DH) has been extensively applied in particle field measurements due to its promising ability to simultaneously provide the three-dimensional location and in-plane size of particles. Particle detection methods are crucial in hologram data processing to determine particle size and particle in-focus depth, which directly affect the measurement accuracy and robustness of DH. In thi
Expectations on collaboration between public authorities and civil society organizations (CSOs) have increased in Sweden the past decades, partly due to changes in the organization of welfare services. This article investigates a collaborative project within the migrant integration policy area. It is a collaboration between the employment offices in a region of Sweden and local CSOs with the commo
A long-standing discussion is to what extent patents can be used to monitor trends in innovation activity. This study quantifies the amount and quality of information about actual innovation contained in the patent system, based on 4,460 Swedish innovations (1970-2015) that have been matched to international patents. The results show that most innovations were not patented and that among those tha
Objective: To examine the relation between different types of alcoholic drinks and upper digestive tract cancers (oropharyngeal and oesophageal). Design: Population based study with baseline assessment of intake of beer, wine, and spirits, smoking habits, educational level, and 2-19 years' follow up on risk of upper digestive tract cancer. Setting: Denmark. Subjects: 15,117 men and 13,063 women ag
Dynamic glucose enhanced (DGE) MRI is used to study the signal intensity time course (tissue response curve) after D-glucose injection. D-glucose has potential as a biodegradable alternative or complement to gadolinium-based contrast agents, with DGE being comparable to dynamic contrast enhanced (DCE) MRI. However, the tissue uptake kinetics as well as the detection methods of DGE differ from DCE,
Many hand-held or mixed reality devices are used with a single sensor for 3D reconstruction, although they often comprise multiple sensors. Multi-sensor depth fusion is able to substantially improve the robustness and accuracy of 3D reconstruction methods, but existing techniques are not robust enough to handle sensors which operate with diverse value ranges as well as noise and outlier statistics
In recent decades, with the advancement of technologies facilitating reproduction, parents have been able to make decisions regarding their childrens’ reproductive potential: to preserve their fertility when threatened by genetic conditions or medical treatment; to use their gametes or embryos to make grandchildren; or even to collect their gametes posthumously and then use them to make grandchild
Forty-two chapters have been structured according to the toxicities in cancer entities, and the late effects and follow-up proposals have been discussed by European and American authors. Cancer diseases in children, adolescents and young adults are treated within specific treatment protocols and can produce different late effects that will have to be cared for by specific follow-up recommendations
Progressive habitat fragmentation threatens plant species with narrow habitat requirements. While local environmental conditions define population growth rates and recruitment success at the patch level, dispersal is critical for population viability at the landscape scale. Identifying the dynamics of plant meta-populations is often confounded by the uncertainty about soil-stored population compar
We present novel developments for the highly efficient evaluation of complex linear response functions of a multiconfigurational self-consistent field (MCSCF) wave function as implemented in MultiPsi. Specifically, expressions for the direct evaluation of linear response properties at given frequencies using the complex polarization propagator (CPP) approach have been implemented, within both the
Transport electrification in Sweden is moving at a fast pace. Grid impact studies from EVs predominantly consider low-voltage grids. However, as the share of electric cars is rapidly increasing, potential grid impact at higher voltage levels needs to be considered. This paper presents a probabilistic approach to generate aggregated charging profiles for home charging at a sub-transmission grid lev
This article provides a step-by-step guideline for measuring and analyzing visual attention in 3D virtual reality (VR) environments based on eye-tracking data. We propose a solution to the challenges of obtaining relevant eye-tracking information in a dynamic 3D virtual environment and calculating interpretable indicators of learning and social behavior. With a method called "gaze-ray casting," we
Populärvetenskaplig sammanfattning Evolution av stabilitet i ett rovdjur-bytessystem För att göra en matematisk modell av hur rovdjur och byten växelverkar med varandra ställer man upp varsin ekvation för populationernas tillväxthastighet. Dessa beskriver hur rovdjuren och bytena beror av varandra och tiden. Eftersom rovdjuren är beroende av att äta byten för att överleva påverkar de bytespopulaAbstract This master's thesis aim to see if fluctuations in the environment can make a stable predator-prey system naturally evolve into an unstable system. In the paper “Prey adaptation as a cause of predator-prey cycles” (Evolution, 1997), Abrams and Matsuda uses numerical methods to investigate the stability properties of a predator-prey system and looks at the effect that the unstable pop
An implementation to convert one of Adobes Flash file-format (xfl) to HTML5 has been created. The problems that need to be solved for completion of this converter are. What programming language should be used that is suitable for the application and locating some form of documentation of the file-format xfl. Javascript was chosen for implementation, but a usable documentation of xfl was not to be
Synen på alkoholmissbruk har skiftat genom tiderna. Till en början sågs missbruket som en samhällsfara där lösningen var att isolera individen från övriga samhället. Detta synsätt skiljer sig från det nuvarande där det finns ett samhällsintresse för en arbetstagare som lider av alkoholmissbruk för att denne ska få tidiga stödinsatser och förhoppningsvis med hjälp av dessa åtgärder kvarbli i arbetsThe perception of alcohol abuse has evolved over time. Initially, abuse was seen as a societal threat, with the solution being to isolate the individual from the rest of society. This perspective differs from the current approach, where there is a societal interest in supporting an employee suffering from alcohol abuse through early interventions, The aim is to support the employee to remain in th
