Covid-19 increased the social and economic vulnerability of island societies. Swedish islands are key tourism destinations but are also home to many island residents. Previous studies have high-lighted the impact of Covid-19 on core areas, but our knowledge of its impact on island communities is lac-king. We use phenomenology to analyse how communities in small Swedish islands perceive the impact

Impulsive noise is one of the most challenging forms of interference in an underwater acoustic environment. In this paper, we present an underwater acoustic channel deconvolution method based on a sparse representation framework. The application of the method enables a channel impulse response reconstruction that is robust to impulsive noise. By exploiting the inherent structure in the channel res

I denna avhandling studeras en särskild kategori av subharmoniska funktioner, det vill säga reellvärda funktioner vars värde i en specifik punkt är mindre än eller lika med funktionens medelvärde på sfärer med centrum i punkten. Sådana funktioner återfinns på flera håll i vetenskapen. Ett exempel är temperaturen i ett bord efter att en värmeslinga slagits på längs bordets rand. I detta fall kommerWe study the Perron–Bremermann envelope P(μ, φ):=sup{u(z) ; u ∈ PSH(Ω), (ddcu)n≥ μ, u^* ≤ φ} on a B-regular domain Ω. Such envelopes occupy a central position within pluripotential theory as they, for suitable μ and φ harmonic and continuous on the closure of Ω, constitute unique solutions to the Dirichlet problem for the complex Monge–Ampère operator. Much is also known about the measures that gu

Despite aggressive treatment, the 5-year event-free survival rate for children with high-risk neuroblastoma is <50%. While most high-risk neuroblastoma patients initially respond to treatment, often with complete clinical remission, many eventually relapse with therapy-resistant tumors. Novel therapeutic alternatives that prevent the recurrence of therapy-resistant tumors are urgently needed. To u

Telomeres are the conservative sequence repeats located at the end of linear chromosomes that have been the focus of intensive research across many disciplines over the last four decades. They function as a cap to protect the chromosome ends from fusion to other chromosomes and to prevent chromosome degradation. Telomere shortening is thought to be involved in ageing, reflecting or even causing ag
