  • The European Hematology Association Roadmap for European Hematology Research : a consensus document
  • 2016
  • Ingår i: Haematologica. - Pavia, Italy : Ferrata Storti Foundation (Haematologica). - 0390-6078 .- 1592-8721. ; 101:2, s. 115-208

    • The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at (sic)23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap. The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders. The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients.

  • Handling Non-IID Data in Federated Learning : An Experimental Evaluation Towards Unified Metrics
  • 2023
  • Ingår i: 2023 IEEE International Conference on Dependable, Autonomic and Secure Computing, International Conference on Pervasive Intelligence and Computing, International Conference on Cloud and Big Data Computing, International Conference on Cyber Science and Technology Congress, DASC/PiCom/CBDCom/CyberSciTech 2023. - : Institute of Electrical and Electronics Engineers (IEEE). - 9798350304602 ; , s. 762-770
  • Konferensbidrag (refereegranskat)abstract
    • Recent research has demonstrated that Non-Identically Distributed (Non-IID) data can negatively impact the performance of global models constructed in federated learning. To address this concern, multiple approaches have been developed. Nonetheless, previous research lacks a cohesive overview and fails to uniformly assess these strategies, resulting in challenges when comparing and choosing relevant options for real-world scenarios. This study presents a structured survey of cutting-edge techniques for handling the Non-IID data, accompanied by proposing a metric to develop a standardized approach for assessing data skew and its harmony with the appropriate approach. The findings affirm the metric's suitability as a heuristic for assessing data skew in distributed datasets without having insight into client data, serving both scientific and practical purposes and thus supporting the selection of handling strategies. This preliminary research establishes the foundation for discussing standardizing methodologies for evaluating data heterogeneity in federated learning. © 2023 IEEE.

  • Progress towards monitoring of microlitter in Scandinavian marine environments
  • 2018
  • Ingår i: TemaNord, 2018, 551, 2018. - Copenhagen : Nordic Council of Ministers.
  • Tidskriftsartikel (refereegranskat)abstract
    • Four different case studies were carried out to determine dominating microlitter types from urban environments to the regional Scandinavian seas (eastern North Sea). The sampling was both from sediment near sources (urban runoff and road dust sediment), and further out from coastal sediments. The sea surface layer and subsurface samples was taken in two different gradients, in the Oslo and Roskilde fjords, where also blue mussels were sampled. Best available technologies for sampling each compartment was used and evaluated, and while the water samples was analysed as collected, the sediment and biota samples needed some pretreatment of chemical digestion and/or heavy density liquid floatation or elutriation.In order to develop visual identification as objective as possible, a visual and physical observation scheme was proposed. The visual identification scheme should be complemented with spectroscopic identification to different degrees depending on the size fractions.Spectroscopic identification is still often a quite time-consuming process, meaning that for monitoring purposes it is not currently advisable to aim to identify all particles during monitoring studies. Until fully or partly automated spectroscopic methods are available they are still important tools for verification of representative types of particles in samples above 100 μm.The amount of particles that should be identified to provide adequate compositional information would be dependent on the aim of the study as well as the type and composition of the samples. However, in order to do monitoring and include sample composition in the results a minimum of 100 of the fewest particles should be counted in a sample to achieve 10% standard deviation in terms of counting statistical uncertainty.The field is however rapidly evolving, and automated procedures are already being published. For research purposes and more detailed monitoring and screening studies spectroscopic methods can aside from providing particle identification also give clues on additives and level of degradation.The most common types of microlitter found varied between studies but common trends could be identified between the road tunnel sediment and the urban creek sediment that these contained black particles resembling tire rubber from both visual and tactile tests, and also asphalt, charcoal, oil/tar particles and road marker particles. In the coastal water samples the surface layer was dominated by polystyrene foam particles and polyethylene fragments and films.In the subsurface water samples fibres, films and fragments of plastic was most common. In both the Gothenburg urban creek sediment and Oslo fjord surface water samples particles that could be related to artificial sports turf (polyethylene green grass and clear cut, tire granulate) was observed. The microlitter in mussels was dominated by fibres. The approach of using gradient studies, and include both near source sampling as well as recipient gradient sampling, was concluded to be very suitable to determine sources and fate.

  • Progress towards monitoring of microlitter in Scandinavian marine environments: State of knowledge and challenges
  • 2018
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Microlitter consists of minute particles of anthropogenic or processed natural material. The project brings together research groups to conduct specific case studies in gradients from near urban sources such as the traffic environment and cities to the coastal water and sediments in order to study the relative occurrence of specific sources and their environmental dispersion and distribution. The conclusion were first that in sediments from the road environment (tunnel runoff water), tire particles, asphalt and road markings could be identified, and in the urban creek sediments many black particles including elastomers, charcoal-like and oil and soot where in high abundance and decreased rapidly out in the recipient. The results emphasize the role of the cities as hotspot source functions for microlitter in the coastal environment and also where mitigating measures could be directed.

  • A Synthesis of Marine Monitoring Methods With the Potential to Enhance the Status Assessment of the Baltic Sea
  • 2020
  • Ingår i: Frontiers in Marine Science. - Lausanne : Frontiers Media S.A.. - 2296-7745. ; 7
  • Tidskriftsartikel (refereegranskat)abstract
    • A multitude of anthropogenic pressures deteriorate the Baltic Sea, resulting in theneed to protect and restore its marine ecosystem. For an efficient conservation,comprehensive monitoring and assessment of all ecosystem elements is of fundamentalimportance. The Baltic Marine Environment Protection Commission HELCOMcoordinates conservation measures regulated by several European directives. However,this holistic assessment is hindered by gaps within the current monitoring schemes.Here, twenty-two novel methods with the potential to fill some of these gaps andimprove the monitoring of the Baltic marine environment are examined. We asked keystakeholders to point out methods likely to improve current Baltic Sea monitoring. Wethen described these methods in a comparable way and evaluated them based ontheir costs and applicability potential (i.e., possibility to make them operational). Twelvemethods require low to very low costs, while five require moderate and two high costs.Seventeen methods were rated with a high to very high applicability, whereas fourmethods had moderate and one low applicability for Baltic Sea monitoring. Methodswith both low costs and a high applicability include the Manta Trawl, Rocket, SedimentCorer, Argo Float, Artificial Substrates, Citizen Observation, Earth Observation, theHydroFIARpH system, DNA Metabarcoding and Stable Isotope Analysis. © 2020 Mack, Attila, Aylagas, Beermann, Borja, Hering, Kahlert, Leese, Lenz, Lehtiniemi, Liess, Lips, Mattila, Meissner, Pyhälahti, Setälä, Strehse, Uusitalo, Willstrand Wranne and Birk.
