1. 6. Enhancing Censorship Resistance in the Tor Anonymity Network

   Författare :Philipp Winter; Stefan Lindskog; Simone Fischer-Hübner; Steven Murdoch; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tor; censorship; anonymity; network; Computer Science; Datavetenskap;

   Sammanfattning : BaksidestextThe Tor network was originally designed as low-latency anonymity network.However, as the years progressed, Tor earned a reputation as also being a useful tool to circumvent Internet censorship. At times, the network counted 30,000 users only from China. LÄS MER

3. 7. Induction and functional role of type I interferon in bacterial infection of macrophages

   Författare :Elin Movert; Infektionsimmunologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; macrophage; Streptococcal M proteins; Mycobacterium marinum; Type I interferon; Infection;

   Sammanfattning : Infection represents an evolutionary arms race between pathogen and host. Thus, scientists find that pathogenic microbes have evolved elegant strategies to manipulate or avoid our immune system, allowing them to persist within the human population. LÄS MER

4. 8. Ecology and evolution in a host-parasitoid system : Host search, immune responses and parasitoid virulence

   Författare :Lisa Fors; Peter Hambäck; Wertheim Bregje; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Host-parasitoid interactions; Plant-herbivore interactions; Host search; Volatiles; Pheromones; Geographic variation; Cellular defence; Melanisation; Encapsulation; Asecodes; Galerucella; Plant Ecology; växtekologi;

   Sammanfattning : In host-parasitoid systems, there is a continuous coevolutionary arms race where each species imposes a strong selection pressure on the other. The host needs to develop defence strategies in order to escape parasitism and the parasitoid must evolve counter-defence strategies in order to overcome the host’s immune defence and successfully reproduce.

5. 9. Sexual conflict and male-female coevolution in the fruit fly

   Författare :Urban Friberg; Göran Arnqvist; Daniel Promislow; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cryptic male mate choice; Drosophila melanogaster; female mate choice; multiple mating; sexual conflict; sexually antagonistic coevolution; sexual selection; speciation; sperm competition; Biology; Biologi;

   Sammanfattning : Harmony and cooperation was for long believed to dominate sexual interactions. This view slowly started to change 25 years ago and is today replaced with a view where males and females act based on what is best from a costs-benefits perspective. LÄS MER

7. 10. Male-female Coevolution in Bruchid seed beetles

   Författare :Johanna Liljestrand Rönn; Göran Arnqvist; Nina Wedell; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Animal Ecology; zooekologi; Animal Ecology;

   Sammanfattning : Male-female coevolution is at the heart of biology. It is responsible for much of the diversity we see in behaviour and morphology, and it is thought to be an important engine of speciation. LÄS MER
