1. 21. Coreceptor usage and sensitivity to neutralization of HIV-1 and HIV-2

   Författare :Yu Shi; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :HIV-1; HIV-2; pathogenesis; neutralization; coreceptor usage; envelop sequence; glycosylation; U87.CD4 cells; GHOST 3 cells; CCR5; CXCR4;

   Sammanfattning : The aim of this project was to study neutralization and coreceptor use in HIV-1 and HIV-2. The first step was to develop a simple and standardized assay for detection and quantification of HIV- 1 neutralizing activity in human sera. LÄS MER

3. 22. Consistent Nonlinear Interactions for the Graviton

   Författare :Angnis Schmidt-May; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis investigates various aspects of massive gravity and bimetric gravity which be- long to a certain class of modifications of general relativity. It provides an introduction to linear massive gravity in flat backgrounds, before reviewing the construction of consistent nonlinear massive gravity that avoids the Boulware-Deser ghost instability.

   Författare :Nils Claesson; Göran Du Rées; Karin Hansson; Niclas Östlind; Stockholms konstnärliga högskola; []
   Nyckelord :HUMANIORA; HUMANITIES; film; animation; stop motion; workstories; life stories; films; experimental art practice in animated film; literature; performance; transfigurations; politics of memory; the inverted Orpheus myth; Bergman; Strindberg; artistic research; improvisation; embodiment; Gestaltung-fiction; Performativa och mediala praktiker; med inriktning mot film och media koreografi opera scen; Performative and mediated practices; with specializations in choreography film and media opera performing arts;

   Sammanfattning : The Ghost Machine is a practice-based research project that explores the process of embodiment in animated film. It describes the process of transfiguration from the artist’s/auteur’s point of view and not from an outside position. LÄS MER

5. 24. Classically Consistent Theories of Interacting Spin-2 Fields

   Författare :Angnis Margreta Schmidt-May; Fawad Hassan; Cedric Deffayet; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

   Sammanfattning : This doctoral thesis comprises a study of recently developed nonlinear theories for massive spin-2 fields that go by the names of Massive Gravity and Bimetric Theory. As we demonstrate in a Hamiltonian analysis, the construction of these theories avoids the notorious Boulware-Deser ghost instability that generically plagues nonlinear spin-2 interactions and renders their description inconsistent.

7. 25. Rethinking Speculative Execution from a Security Perspective

   Författare :Christos Sakalis; Magnus Själander; Alexandra Jimborean; Stefanos Kaxiras; Josep Torrellas; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer architecture; speculative execution; processor; security; out-of-order execution; side-channel; microarchitectural replay; microarchitecture; Delay-on-Miss; Ghosts; Delay-on-Squash; Computer Science; Datavetenskap;

   Sammanfattning : Speculative out-of-order execution is one of the fundamental building blocks of modern, high-performance processors. To maximize the utilization of the system's resources, hardware and software security checks in the speculative domain can be temporarily ignored, without affecting the correctness of the application, as long as no architectural changes are made before transitioning to the non-speculative domain.
