Annan publikation (refereegranskat)abstract
- Lyxkonsumtion, Stureplansbrats, medelklass och överklass diskuteras allt mer. Samtidigt har den partipolitiska borgerligheten tagit över regeringsmakten. Men vad innebär det att tala om borgerlighet i dagens Sverige? Vilka tillhör denna sociala kategori och vad utmärker den? I Fronesis nr 24 dissekeras gårdagens såväl som dagens borgerlighet.

Probabilistic Routing Protocol for Intermittently Connected Networks
- 2007
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This document defines PRoPHET, a Probabilistic Routing Protocol using History of Encounters and Transitivity. PRoPHET is a routing protocol for intermittently connected networks, where there is no guarantee that a fully connected path between source and destination exists at any time, rendering traditional routing protocols unable to deliver messages between hosts. These networks are examples of networks where the Delay-Tolerant Network architecture[1] is applicable. The document presents an architectural overview followed by the protocol specification.

OxyR : an important regulator of the oxidative stress response of Francisella tularensis LVS
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- An essential part of the oxidative stress response in Gram-negative bacteria is the H2O2-activated transcriptional regulator OxyR. Although it is much studied in common bacteria such as Escherichia coli, little is known about it about its role in the facultative intracellular bacterium Francisella tularensis. Here, we studied the role of OxyR in the strain F. tularensis LVS. We studied the effects of ROS on the LVS, ΔoxyR, ΔkatG and ΔoxyR/ΔkatG. The latter mutants lack expression of catalase, the function of which is important for degradation of reactive oxygen species, especially H2O2. The in vitro response of these mutants to defined ROS was assessed using H2O2, the O2- generating agent paraquat, and the ONOO- generator SIN-1. ΔoxyR was more susceptible to all ROS than LVS, as was ΔkatG, with the exception of O2-. Strikingly, ΔoxyR/ΔkatG was significantly more susceptible to all ROS tested compared to either single deletion mutant. Also the catalase activity was assessed and whereas LVS significantly upregulated the enzymatic activity in response to H2O2, this did not occur in the ΔoxyR mutant. Gene expression by ΔoxyR was compared to LVS and it was found that there was down-regulation of fur, katG, sodB, sodC, furA, and in particular of ahpC, in the mutant. LVS, ΔoxyR and ΔkatG replicated efficiently in bone marrow-derived macrophages, whereas ΔoxyR/ΔkatG showed no replication. In mice, the ΔoxyR mutant displayed impaired replication in liver but intact replication vs. LVS in spleen. Collectively, our results demonstrate an important role of OxyR in the oxidative stress response and virulence of F. tularensis. The combined mutation of ΔoxyR/ΔkatG led to severely impaired handling of oxidative stress.

Proposed Design Choices for IoT over Information Centric Networking
- 2015. - 10
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This document discusses and describes design choices made in order to utilize Information Centric Networking (ICN) for the Internet of Things (IoT). Based on requirements and challenges identified in draft-zhang-icnrg-iotchallenges-00, we propose design choices for an IoT architecture to handle these requirements, while providing efficiency and scalability. An objective is to, as far as possible, not require IoT specific changes of the ICN architectures per se, but we do indicate some potential modifications of ICN that would improve efficiency and scalability for IoT and other applications. Furthermore, the document starts outlining how to map the proposed design choices to existing ICN architectures, in a first instance shown for CCN1.0.
