”We went out to steal a bike late one night” : On the harmonious disharmony of noise
Introduction: Sounds of Science : Composition, recording and listening as laboratory practice
Research in music, sound art and sound studies is not only a matter of listening and experiencing auditory phenomena. Neither is it limited to the study of scores, graphic notations or sonograms. With the still increasing expansion of practice-based research methods, many artists and scholars of music, sound art and sound studies now gain their knowledge through their creative practice, or through

Music Education and Democratisation : Policy processes and discourses of inclusion of all children in Sweden's Art and Music Schools
The aim of this thesis is to critically investigate the discourses of Sweden’s Art and Music Schools (SAMS, kulturskolor in Swedish) connected to policy processes for the democratisation of music education for all children and adolescents. A further aim is to contribute to knowledge on the development and enactment of policy processes for the democratisation of music education.

Glymphatic pathways in the gyrencephalic brain
Identification of the perivascular compartment as the point of exchange between cerebrospinal fluid (CSF) and interstitial fluid mediating solute clearance in the brain, named the glymphatic system, has emerged as an important clearance pathway for neurotoxic peptides such as amyloid-beta. However, the foundational science of the glymphatic system is based on rodent studies. Here we investigated w
Blodkomponenter och helblod – så framställs och används de
Krav på innehåll i blodkomponenter, virustest och kvalitetskriterier regleras i ett EU-direktiv och i Socialstyrelsens föreskrifter. Blodtransfusioner är en vanlig och viktig medicinsk behandling.Det saknas nationella riktlinjer för transfusionsindikationer och uppföljning av blodtransfusioner i Sverige.Det finns medicinsk evidens för en generellt restriktiv transfusionsstrategi.Vid stora blödningSweden does not have a national blood authority and guidelines for blood transfusions are lacking, leading to varying routines of production and usage of blood in the different regions. The minimum quality requirements are defined in EU Directive 2002/98/EG and in the Swedish SOSFS 2009:28. The standard blood components are red blood cells, plasma and platelets, while special components such as ir
Spiritual geopolitics of Georgia's territorial integrity
This paper represents a study of the geopolitical reasoning of the Georgian Orthodox Church (GOC) and its leader Patriarch Ilia II regarding the question of Georgia's territorial integrity. Does the GOC's territorial discourse complement or challenge Georgia's territorial nationalism? The empirical analysis of the geopolitical discourses of Patriarch Ilia II in the early 1990s and in the wake of t
Birth and destruction of collective oscillations in a network of two populations of coupled type 1 neurons
We study the macroscopic dynamics of large networks of excitable type 1 neurons composed of two populations interacting with disparate but symmetric intra- and inter-population coupling strengths. This nonuniform coupling scheme facilitates symmetric equilibria, where both populations display identical firing activity, characterized by either quiescent or spiking behavior, or asymmetric equilibria
Optimal Self-Induced Stochastic Resonance in Multiplex Neural Networks : Electrical vs. Chemical Synapses
Electrical and chemical synapses shape the dynamics of neural networks, and their functional roles in information processing have been a longstanding question in neurobiology. In this paper, we investigate the role of synapses on the optimization of the phenomenon of self-induced stochastic resonance in a delayed multiplex neural network by using analytical and numerical methods. We consider a two
First-order synchronization transition in a large population of strongly coupled relaxation oscillators
Onset and loss of synchronization in coupled oscillators are of fundamental importance in understanding emergent behavior in natural and man-made systems, which range from neural networks to power grids. We report on experiments with hundreds of strongly coupled photochemical relaxation oscillators that exhibit a discontinuous synchronization transition with hysteresis, as opposed to the paradigma
Understanding the dynamics of biological and neural oscillator networks through exact mean-field reductions : a review
Many biological and neural systems can be seen as networks of interacting periodic processes. Importantly, their functionality, i.e., whether these networks can perform their function or not, depends on the emerging collective dynamics of the network. Synchrony of oscillations is one of the most prominent examples of such collective behavior and has been associated both with function and dysfuncti
Cerebrospinal fluid influx drives acute ischemic tissue swelling
Stroke affects millions each year. Poststroke brain edema predicts the severity of eventual stroke damage, yet our concept of how edema develops is incomplete and treatment options remain limited. In early stages, fluid accumulation occurs owing to a net gain of ions, widely thought to enter from the vascular compartment. Here, we used magnetic resonance imaging, radiolabeled tracers, and multipho
Directed Flow of Information in Chimera States
We investigated interactions within chimera states in a phase oscillator network with two coupled subpopulations. To quantify interactions within and between these subpopulations, we estimated the corresponding (delayed) mutual information that—in general—quantifies the capacity or the maximum rate at which information can be transferred to recover a sender's information at the receiver with a van
Chaos in Kuramoto oscillator networks
Kuramoto oscillators are widely used to explain collective phenomena in networks of coupled oscillatory units. We show that simple networks of two populations with a generic coupling scheme, where both coupling strengths and phase lags between and within populations are distinct, can exhibit chaotic dynamics as conjectured by Ott and Antonsen [Chaos 18, 037113 (2008)]. These chaotic mean-field dyn
Transitions from trees to cycles in adaptive flow networks
Transport networks are crucial to the functioning of natural and technological systems. Nature features transport networks that are adaptive over a vast range of parameters, thus providing an impressive level of robustness in supply. Theoretical and experimental studies have found that real-world transport networks exhibit both tree-like motifs and cycles. When the network is subject to load fluct
Chimera states in two populations with heterogeneous phase-lag
The simplest network of coupled phase-oscillators exhibiting chimera states is given by two populations with disparate intra- and inter-population coupling strengths. We explore the effects of heterogeneous coupling phase-lags between the two populations. Such heterogeneity arises naturally in various settings, for example, as an approximation to transmission delays, excitatory-inhibitory interact
Modeling of Kidney Hemodynamics : Probability-Based Topology of an Arterial Network
Through regulation of the extracellular fluid volume, the kidneys provide important long-term regulation of blood pressure. At the level of the individual functional unit (the nephron), pressure and flow control involves two different mechanisms that both produce oscillations. The nephrons are arranged in a complex branching structure that delivers blood to each nephron and, at the same time, prov
