Swedish public service radio has during its almost 100 years undergone several transformations due to technical, societal and cultural changes. A transformation still in motion can be attributed to the arrival of the internet, the digitalization of the recording, storage and distribution of sound, as well as the fast paced evolution of the global media landscape. When the mp3-file and the internet

We present an online learning analysis of minimax adaptive control for the case where the uncertainty includes a finite set of linear dynamical systems. Precisely, for each system inside the uncertainty set, we define the model-based regret by comparing the state and input trajectories from the minimax adaptive controller against that of an optimal controller in hindsight that knows the true dynam

We present a methodology for establishing the existence of quadratic Lyapunov inequalities for a wide range of first-order methods used to solve convex optimization problems. In particular, we consider (i) classes of optimization problems of finite-sum form with (possibly strongly) convex and possibly smooth functional components, (ii) first-order methods that can be written as a linear system on

We present an exact dimensionality reduction for dynamics of an arbitrary array of globally coupled complex-valued Riccati equations. It generalizes the Watanabe-Strogatz theory [Integrability of a globally coupled oscillator array, Phys. Rev. Lett. 70, 2391 (1993).PRLTAO0031-900710.1103/PhysRevLett.70.2391] for sinusoidally coupled phase oscillators and seamlessly includes quadratic integrate-and

Arbetet ämnar ge ett teoretiskt perspektiv på utformningen av det svenska lagspråket. Genom en retorisk argumentationsanalys, grundad i Chaïm Perelmans teori om föreställda publiker och Lloyd Bitzers teori om den retoriska situationen, utreds konsumentlagstiftningen i sin egenskap som meningsbärare mellan en retorisk avsändare och en retorisk mottagare. Den gamla och den nya konsumentköplagen jämfThe thesis aims to provide a theoretical perspective on the language used in the Swedish law. Through a rhetorical argumentation analysis, grounded in Chaïm Perelman’s theory of perceived audiences and Lloyd Bitzer’s theory of the rhetorical situation, the consumer sales act is investigated in its capacity as a carrier of meaning between a speaker and an audience. The old and the new consumer sale

Climate change forces organisms to adapt to new habitats with migratory birds facing unique challenges, especially when they initiate the migratory behaviour to gain mass for migration. Many bird species adapt to their ancestral latitudes by changing their behaviour and physiology to the photic environment. Current predictions indicate that climate change can also limit range shift capacity due to

Integrated silicon photonics is emerging as the most promising route for interconnects and on-chip com- munication to keep up with the constant performance increase of CMOS (complementary metal oxide semiconductor) technology. Among the components of integrated photonics, the electro-optic modulators implemented on silicon are suffering from high insertion losses and high power consumption. Due to

Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. By introducing an enzyme-based sunscreen for daily facial use these damages may be reduced while also providing exfoliation and hydration

This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. Collective behavior, indicating a QGP phase, is studied through anis

The amygdala was highlighted as an early site for neurofibrillary tau tangle pathology in Alzheimer's disease in the seminal Braak & Braak article (1991). This knowledge has, however, only received traction recently with advances in imaging and image analysis techniques. Here, we provide a cross-disciplinary overview of pathology and neuroimaging studies on the amygdala. These studies provide

This study investigates and describes the Haemosporidian parasite composition of the host bird community in the Ammarnäs area from 1999 to 2020, along with the effect of avian malaria infection on host body condition, based on a data set comprising body measurements and infection status for the Plasmodium, Haemoproteus, and Leucocytozoon genera in captured birds from five sample years, and also a

Det pågår ständigt en utveckling för att minska både risker för miljö och hälsa inom den kemiska industrin. Oftast handlar det om att förbättra existerande processer eller att helt enkelt hitta nya vägar till samma produkt och i grunden ligger forskning bakom framgångarna.Polyurethane is a widely used polymer with a lot of different applications due to its versatility and often resilient properties. The polymeris often prepared as a two component system consisting of polyols and isocyanates and can be cured at relatively low temperatures. Even though the formed polymer is hazardless the isocyanate used in the manufacture is dangerous in itself, but even more so is

Häri beskrivs en metod för sulfonering av EPDM. Detta examensarbete syftade till att tillverka jonledande, elastomera filmer för korrosionshämmande packningsmaterial. För att uppnå jonledning svälldes vulkaniserade prover i 1,2-dikloretan innan sulfonering med trimetylsilyl klorsulfonat som sulfoneringsagent. Förändringar i mekaniska och termiska egenskaper utvärderades, samtidigt som jonledning sHerein a method for sulfonation of EPDM is described. This thesis aimed to prepare ion conducting elastomer films for use as corrosion inhibiting materials. To achieve ion conductivity, vulcanised samples were swelled in 1,2-dichloroethane and sulfonated using trimethylsilyl chlorosulfonate as sulfonating agent. Changes in mechanical, thermal and ion conductive properties were assessed. Sulfonated

Under de senaste åren har stora resurser lagts på forskning kring utvecklingen av biomaterial för ersättning av fossil-baserade material. Förpackningsindustrin i synnerhet är en sektor känd för att generera enorma mängder fast avfall, med produkter som inte sällan har betydligt kortare livslängd än sina materialkomponenter. Polylaktid (PLA) är en mångsidig biopolymer som används kommersiellt föIn recent years, large efforts have been put into the research of biomaterial synthesis for the replacement of fossil-based materials. Particularly in the packaging industry, a sector responsible for generating enormous amount of solid waste in which products have a considerably shorter life span than their material components. Polylactic acid (PLA) is a versatile, commercial biopolymer used fo

All organisms are made up ofcells, the smallest functional unit of life. While organisms such asplants and animalscan consist of trillions of cells, others consist of just one cell.One group of unicellularorganisms is called bacteria. Because oftheir small size, bacteria and other microscopic small organisms are classified as microorganisms. In nature, mostbacteria do not live as single cells. Th

This article takes the awarding of William B. Gartner as a winner of the FSF-Nutek Award (in 2005) as a reason to engage more thoroughly with his production. From the perspective of a European School of Entrepreneurship, we focus in particular on the hermeneutic/phenomenological side of Gartner's research output and seek to operate as inspired readers of this work as we identify its central tenden

Decidualization is essential to rodent and primate pregnancy. Senescence is increased during decidualization. Failure of senescence clearance during decidualization will cause pregnancy abnormality. Caveolin-1 is located in plasmalemmal caveolae and involved in senescence. However, whether caveolin-1 is involved in decidualization remains undefined. In this study, we examined the expression, regul

We analyze the circumgalactic medium (CGM) for eight commonly-used cosmological codes in the AGORA collaboration. The codes are calibrated to use identical initial conditions, cosmology, heating and cooling, and star formation thresholds, but each evolves with its own unique code architecture and stellar feedback implementation. Here, we analyze the results of these simulations in terms of the str

Introduction: Proteomics may help discover novel biomarkers and underlying mechanisms for cardiovascular disease. This could be useful for childhood cancer survivors as they show an increased risk of cardiovascular disease. The aim of this study was to investigate circulating cardiovascular proteins in young adult survivors of childhood cancer and their relationship to previously reported subclini
