2. 6. Beyond Generative Sufficiency : On Interactions, Heterogeneity & Middle-Range Dynamics

   Author : Martin Arvidsson; Peter Hedström; Marc Keuschnigg; Duncan Watts; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Collective dynamics; Social networks; Heterogeneity; Digital trace data; Agent-based simulation; Social mechanisms; Analytical sociology; Computational social science;

   Abstract : Explaining how properties at the level of individuals translate into properties at the level of collectives is a core objective of sociology. Because the social world is characterized by complex webs of social interdependencies, establishing how micro and macro are related to one another requires a detailed understanding of how individuals are influenced by their social environments and the consequences that such influences have for the dynamics of the social process.

4. 7. Aspects of Structural Evolution in Cemented Carbide – Carbide Size, Shape and Stability

   Author : Ida Borgh; Joakim Odqvist; Peter Hedström; Annika Borgenstam; Jean-Michel Missiaen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cemented carbide; Ti; Zr C; Coarsening; Phase separation; C-activity; initial WC powder size; electron backscattered diffraction; microscopy; X-ray diffraction;

   Abstract : Cemented carbide is a composite material used in applications like cutting tools and rock drilling inserts. The material commonly consists of WC grains embedded in a Co-rich binder phase and the material properties strongly depend on the WC grain size. READ MORE

5. 8. Carbides in martensitic medium carbon low alloyed tool steels studied with small angle scattering techniques, electron microscopy and atom probe tomography

   Author : Erik Claesson; Peter Hedström; Hans Magnusson; Erik Offerman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low alloyed tool steel; Martensite; Small angle scattering; Scanning transmission electron microscopy; Energy dispersive x-ray spectroscopy; atom probe tomography; Scanning precession electron diffraction; Precipitation; carbides; Tempering.; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : Medium carbon low alloyed tool steels are used today in various areas to shape plastics, nonferrous metals, and steels, and they are crucial in the manufacturing industry. To be effective, tool steels must be strong and tough, and have high wear resistance and temperature stability. READ MORE

6. 9. Immunologic Markers in the Tumor Microenvironment of Classical Hodgkin Lymphoma

   Author : Alex R. Gholiha; Gunilla Enblad; Rose-Marie Amini; Peter Hollander; Gustaf Hedström; Arjan Diepstra; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tumor microenvironment; immunohistochemistry; immune checkpoints; Plasma cells; IL-6 cytokine; Proteomics; CD47.;

   Abstract : In classical Hodgkin lymphoma (cHL), cytokine regulation and cellular composition of the tumor microenvironment (TME) is crucial for tumor cell survival. In paper I, we examined the presence of CD138+ plasma cells and IgG4+ plasma cells in diagnostic cHL biopsies with immunohistochemistry (IHC). READ MORE

7. 10. Mining for Meaning : using computational text analysis for social inquiry

   Author : Miriam Hurtado Bodell; Marc Keuschnigg; Måns Magnusson; Peter Hedström; Laura Nelson; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Text-as-data; Analytical sociology; Meaning-making; Computational text analysis; Computational social science;

   Abstract : People interpret their surroundings through associations, determining what they perceive as belonging or not belonging together. For instance, one individual may view immigrants as a beneficial addition to the domestic labor market, while another may perceive them as a threat to job opportunities for native citizens. READ MORE
