1. 21. Genomic and evolutionary exploration of Asgard archaea

   Författare :Eva F. Caceres; Thijs J. G. Ettema; Simonetta Gribaldo; Uppsala universitet; []
   Nyckelord :archaea; Asgard; eukaryogenesis; metagenomics; genome binning; phylogenetics; phylogenomics; comparative genomics; gene tree-species tree reconciliation; ancestral reconstruction; long-read metagenomics;

   Sammanfattning : Current evolutionary theories postulate that eukaryotes emerged from the symbiosis of an archaeal host with, at least, one bacterial symbiont. However, our limited grasp of microbial diversity hampers insights into the features of the prokaryotic ancestors of eukaryotes. LÄS MER

3. 22. Ultrafast Coherent X-ray Diffractive Nanoimaging

   Författare :Filipe R. N. C. Maia; Janos Hajdu; David van der Spoel; Keith Nugent; Uppsala universitet; []
   Nyckelord :XFEL; Phasing; Image Reconstruction; Single Particle Imaging; Ultrafast Diffraction; X-ray diffraction; Coherent Diffractive Imaging; CXDI;

   Sammanfattning : X-ray lasers are creating unprecedented research opportunities in physics,chemistry and biology. The peak brightness of these lasers exceeds presentsynchrotrons by 1010, the coherence degeneracy parameters exceedsynchrotrons by 109, and the time resolution is 105 times better. LÄS MER

   Sammanfattning : During face-to-face meetings, humans use multimodal information, including verbal information, visual information, body language, facial expressions, and other non-verbal gestures. In contrast, during computer-mediated-communication (CMC), humans rely either on mono-modal information such as text-only, voice-only, or video-only or on bi-modal information by using audiovisual modalities such as video teleconferencing.

5. 24. On low-complexity frequency selective digital filters and filter banks

   Författare :Linnea Rosenbaum; Håkan Johansson; Tapio Saramäki; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital filters; filter banks; modulated; FRM; Electronics; Elektronik;

   Sammanfattning : En filterbank består av flera filter som arbetar tillsammans för att dela upp en signal i olika frekvensband. De kan också användas för att slå ihop signaler separerade i frekvensplanet till en enda. Sedan tidigt 70-tal har man lärt sig att designa förlustfria filterbankar som alltså inte introducerar några som helst fel i systemet. LÄS MER

7. 25. Flow and Friction : On the Tactical Potential of Interfacing with Glitch Art

   Författare :Vendela Grundell; Anna Dahlgren; Mårten Snickare; Max Liljefors; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Glitch; Contemporary Art; Photography; Digital Media; Interface; Internet; Systems Aesthetics; Network Society; Tactics; Phenomenology; Spectatorship; Viewer; Experience; Rosa Menkman; Phillip Stearns; Evan Meaney; konstvetenskap; Art History;

   Sammanfattning : This thesis aims to analyze how interfacing affects viewer experiences and viewer positions, and how glitch art online makes that effect visible. Glitch art is concerned with disruptions in the systems that govern how for instance photography is produced, circulated and displayed in a digital image flow. LÄS MER
