This paper studies the problem of coordinating a group of nth-order integrator systems. As for the well-studied conventional consensus problem, we consider linear and distributed control with only local and relative measurements. We propose a closed-loop dynamic that we call serial consensus and prove it achieves nth order consensus regardless of model order and underlying network graph. This alle

Summary of section A In regard to the first issue a new family of survival functions is proposed. Its purpose is to provide valid and reliabl

The health of coastal marine environments is severely declining with global changes. Proxies, such as those based on microeukaryote communities, can record biodiversity and ecosystem responses. However, conventional studies rely on microscopic observations of limited taxonomic range and size fraction, missing putatively ecologically informative community components. Here, we tested molecular tools

BackgroundChildren and youth who experience divorce are found to have increased risk of emotional and behavioural adjustment problems. Different prevention programmes have been developed to help and support children. Previous studies have focused on the child or the group leader's experience with divorce groups, but studies describing parent's experience are missing. The aim of this study was to e

This thesis comprises of four self-contained papers that use both experimental and applied micro-econometric methods to explore different aspects of gender, health, the decisions we make, and the actions we take. In the first paper we investigate changes in psychiatric diagnoses and their income-related inequalities over time in Sweden and attempt to disentangle the development by decomposing chan

De antroprogena kemikalierna PFAS, som står för poly- och perfluorerade alkylsubstanser, är nästan omöjliga att bryta ned och har en förmåga att ansamlas i oss människor och andra organismer. De är även kopplade till en rad olika hälsoproblem som olika former av cancer, hormonell obalans och fertilitetsproblem. Samtidigt är dessa kemikalier vitt använt i olika industriella samt vardagliga produkteAqueuous Film Forming Foam (AFFF) containing Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) is one of the major sources of groundwater contamination in Sweden. Groundwater contamination caused by the use of AFFF in correlation to fire training events was investigated in Kallinge, Sweden. At the site groundwater was previously used as a drinking water source consequently affecting the inhabit

The article describes how Hindu nationalists are using ‘othering’ and ‘identity signifiers’ to appeal to a broad section of India's fractured population. This, she argues, lies at the root of current religious tensions

Access to water of good quality and quantity has become more challenging because of a changing climate, as well as an increase in the use of natural resources, which has lead to altered water chemistry. One of these changes is known as brownification, resulting from a higher organic matter content causing a yellow-brown color of surface waters. Brownification has a manifold of side effects for the

Ungefär hälften av alla cancerpatienter genomgår strålbehandling, antingen som en enskild behandling eller i kombination med kirurgi och/eller medicinsk behandling. Vid strålbehandling används högenergetisk joniserande strålning för att bekämpa cancerceller. Strålningen orsakar skador på tumörcellernas DNA, men kan även skada friska celler. För att uppnå bästa möjliga behandlingseffekt med minsta FLASH radiotherapy (FLASH-RT) is a promising new approach to radiotherapy that has the potential to transform the field. By administering radiation at ultra-high dose rates (UHDR) on a millisecond timescale, FLASH-RT may increase normal tissue tolerance compared to conventional radiotherapy while maintaining the anti-tumoral effect. However, the short treatment times present unique physical and te

We first define a new multiplication on triangular Banach algebras. Then study amenability, weak amenability, biflatness and biprojectivity of these algebras.
