NetInf Live Video Specification
- 2015. - 10

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This document specifies how the NetInf information-centric network service can be used for transport of live video streaming. To illustrate this it describes a prototype system that was developed to be used at "events with large crowds", e.g., sports events. The specification defines how the used video format is mapped to NetInf named data objects (NDOs). It also describe how NetInf messages are used to transfer the NDOs.

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.

Konferensbidrag (refereegranskat)abstract
- Information Centric Networking (ICN) aims to evolve the Internet infrastructure from a host-centric to a data-centric paradigm. In particular, it improves performance and resource efficiency in events with large crowds where many users in a local area want to generate and watch media content related to that event. In this paper, we present the design of a live video streaming system built on the NetInf ICN architecture and how the architecture was adapted to support live streaming of media content. To evaluate the feasibility and performance of the system, extensive field trials were carried out over several days during a major sports event. We show that our system streams videos successfully with low delay and communication overhead compared with existing Internet streaming services, supporting several thousands of simultaneous users.

Our system streams videos successfully with low delay and communication overhead compared with existing Internet streaming services. It can scale to support several thousands of simultaneous users at a time and is well-suited for events with large crowds and flash crowd scenarios.

Common variation in COL4A1/COL4A2 is associated with sporadic cerebral small vessel disease

Tidskriftsartikel (refereegranskat)abstract
- Objectives:We hypothesized that common variants in the collagen genes COL4A1/COL4A2 are associated with sporadic forms of cerebral small vessel disease.Methods:We conducted meta-analyses of existing genotype data among individuals of European ancestry to determine associations of 1,070 common single nucleotide polymorphisms (SNPs) in the COL4A1/COL4A2 genomic region with the following: intracerebral hemorrhage and its subtypes (deep, lobar) (1,545 cases, 1,485 controls); ischemic stroke and its subtypes (cardioembolic, large vessel disease, lacunar) (12,389 cases, 62,004 controls); and white matter hyperintensities (2,733 individuals with ischemic stroke and 9,361 from population-based cohorts with brain MRI data). We calculated a statistical significance threshold that accounted for multiple testing and linkage disequilibrium between SNPs (p < 0.000084).Results:Three intronic SNPs in COL4A2 were significantly associated with deep intracerebral hemorrhage (lead SNP odds ratio [OR] 1.29, 95% confidence interval [CI] 1.14-1.46, p = 0.00003; r(2) > 0.9 between SNPs). Although SNPs associated with deep intracerebral hemorrhage did not reach our significance threshold for association with lacunar ischemic stroke (lead SNP OR 1.10, 95% CI 1.03-1.18, p = 0.0073), and with white matter hyperintensity volume in symptomatic ischemic stroke patients (lead SNP OR 1.07, 95% CI 1.01-1.13, p = 0.016), the direction of association was the same. There was no convincing evidence of association with white matter hyperintensities in population-based studies or with non-small vessel disease cerebrovascular phenotypes.Conclusions:Our results indicate an association between common variation in the COL4A2 gene and symptomatic small vessel disease, particularly deep intracerebral hemorrhage. These findings merit replication studies, including in ethnic groups of non-European ancestry.
