1. Vulnerability Analysis for Critical Infrastructures
Sammanfattning : The rapid advances in information and communication technology enable a shift from diverse systems empowered mainly by either hardware or software to cyber-physical systems (CPSs) that are driving Critical infrastructures (CIs), such as energy and manufacturing systems. However, alongside the expected enhancements in efficiency and reliability, the induced connectivity exposes these CIs to cyberattacks exemplified by Stuxnet and WannaCry ransomware cyber incidents.

2. A Nordic Perspective on Data Availability for Quantification of Losses due to Natural Hazards
Sammanfattning : Natural hazards cause enormous amounts of damage worldwide every year. Since 1994 more than 1.35 billion people have lost their lives and more than 116 million homes have been damaged. Understanding of disaster risk implies knowledge about vulnerability, capacity, exposure of persons and assets, hazard characteristics and the environment. LÄS MER
3. Risk assessment of natural hazards : Data availability and applicability for loss quantification
Sammanfattning : Quantitative risk assessments are a fundamental part of economic analysis and natural hazard risk management models. It increases the objectivity and the transparency of risk assessments and guides policymakers in making efficient decisions when spending public resources on risk reduction. LÄS MER
4. Brain-derived neurotrophic factor in cerebral ischemia: a quantitative study on surviving and newly formed neurons
Sammanfattning : This study explores the role of brain-derived neurotrophic factor (BDNF) for neuronal vulnerability and neurogenesis following cerebral ischemia in the rat. Cerebral ischemia results in selective neuronal cell loss in specific brain regions. We here demonstrate the rank order of vulnerability in two regions affected by global forebrain ischemia, i.

5. Seawater intrusion risks and controls for safe use of coastal groundwater under multiple change pressures
Sammanfattning : In the era of intense pressures on water resources, the loss of groundwater by increased seawater intrusion (SWI), driven by climate, sea level and landscape changes, may be critical for many people living in commonly populous coastal regions. Analytical solutions have been derived here for interface flow in coastal aquifers, which allow for simple quantification of SWI under extended conditions from previously available such solutions and are suitable for first-order regional vulnerability assessment and mapping of the implications of climate- and landscape-driven change scenarios and related comparisons across various coastal world regions.
