Short-Packet Communications for MIMO NOMA Systems over Nakagami-m Fading : BLER and Minimum Blocklength Analysis
- 2021
-
In: IEEE Transactions on Vehicular Technology. - : Institute of Electrical and Electronics Engineers (IEEE). - 0018-9545 .- 1939-9359. ; 70:4, s. 3583-3598
-
Journal article (peer-reviewed)abstract
- Recently, ultra-reliable and low-latency communications (URLLC) using short-packets has been proposed to fulfill the stringent requirements regarding reliability and latency of emerging applications in 5G and beyond networks. In addition, multiple-input multiple-output non-orthogonal multiple access (MIMO NOMA) is a potential candidate to improve the spectral efficiency, reliability, latency, and connectivity of wireless systems. In this paper, we investigate short-packet communications (SPC) in a multiuser downlink MIMO NOMA system over Nakagami-m fading, and propose two antenna-user selection methods considering two clusters of users having different priority levels. In contrast to the widely-used long data-packet assumption, the SPC analysis requires the redesign of the communication protocols and novel performance metrics. Given this context, we analyze the SPC performance of MIMO NOMA systems using the average block error rate (BLER) and minimum blocklength, instead of the conventional metrics such as ergodic capacity and outage capacity. More specifically, to characterize the system performance regarding SPC, asymptotic (in the high signal-to-noise ratio regime) and approximate closed-form expressions of the average BLER at the users are derived. Based on the asymptotic behavior of the average BLER, an analysis of the diversity order, minimum blocklength, and optimal power allocation is carried out. The achieved results show that MIMO NOMA can serve multiple users simultaneously using a smaller blocklength compared with MIMO OMA, thus demonstrating the benefits of MIMO NOMA for SPC in minimizing the transmission latency. Furthermore, our results indicate that the proposed methods not only improve the BLER performance, but also guarantee full diversity gains for the respective users.

ECCO Guidelines on Therapeutics in Crohns Disease: Surgical Treatment
- 2020
-
In: Journal of Crohn's & Colitis. - : OXFORD UNIV PRESS. - 1873-9946 .- 1876-4479. ; 14:2, s. 155-168
-
Journal article (peer-reviewed)abstract
- This article is the second in a series of two publications relating to the European Crohns and Colitis Organisation [ECCO] evidence-based consensus on the management of Crohns disease. The first article covers medical management; the present article addresses surgical management, including preoperative aspects and drug management before surgery. It also provides technical advice for a variety of common clinical situations. Both articles together represent the evidence-based recommendations of the ECCO for Crohns disease and an update of previous guidelines.

Towards a methodology for longitudinal evaluation of social robotic telepresence for elderly
- 2011
-
In: 1st Workshop on Social Robotic Telepresence at HRI 2011.
-
Conference paper (peer-reviewed)abstract
- This paper describes a methodology for performing longitudinal evaluations when a social robotic telepresence system is deployed in realistic environments. This work is the core of an Ambient Assisted Living Project called ExCITE, Enabling Social Interaction Through Telepresence. The ExCITE project is geared towards an elderly audience and has as aim to increase social interaction among elderly, their family and healthcare services by using robotic telepresence. The robotic system used in the project is called the Giraff robot and over a three year period, prototypes of this platform are deployed at a number of test-sites in different European countries where user feedback is collected and fedback into the refinement of the prototype. In this paper, we discuss the methodology of ExCITE in particular relation to other methodologies for longitudinal evaluation. The paper also provides a discussion of the possible pitfalls and risks in performing longitudinal studies of this nature particularly as they relate to social robotic telepresence technologies.

När historiska händelser får samtidens uppmärksamhet - historikerns roll och relationer till brukare och journalister
- 2022
-
Conference paper (peer-reviewed)abstract
- Då och då uppmärksammar massmedia så kallade historiska skandaler såsom sterilisering, vanvård inom den sociala barnavården, höga dödstal på sinnessjukhus eller behandling av minoritetsbefolkningar. Sådan massmedial uppmärksamhet bidrar ibland till diskussioner i nutida samhällsdebatt om välfärdsstatens roll, om svek till individer i utsatta positioner och om vägar till upprättelse.I sådana sammanhang kan historiker bidra med kunskap och perspektiv, och i den rollen har historiker ofta kontakt med journalister och brukare vilket kan vara berikande men också utmanande. Utmaningarna kan handla om att nå ut och nå fram med reflektioner om komplexa skeenden, om förändrade samhälleliga värderingar, strukturer och synsätt som kan bidra till förklaringar av det som med dagens blick tycks obegripligt. Frågan är hur relevant detta upplevs i en kontext där individer söker svar på varför livet blev som det blev och journalister (ibland) söker säljande scoop.Utifrån egna erfarenheter som historiker som forskar om frågor som får utrymme i dagens samhällsdebatt vill vi i detta rundabordssamtal diskutera historikerns roll och relationer till brukare och journalister. Våra erfarenheter rymmer både engagerade brukare som vill använda forskning som ett argument i en upprättelseprocess till brukare som inte vill medverka i forskning överhuvudtaget. Vi har upplevt journalister som medvetet bortser från den forskning vi redovisar till ambitiösa journalister som stämmer av resultat och formuleringar.Vi har mycket att vinna på goda relationer mellan historiker, brukare och journalister – men hur skapar vi dessa? Hur når vi ut med vår forskning? Hur kan historiker bidra i samtida diskussioner? Hur behåller vi vår professionella integritet i samarbete med brukare? Hur hanterar vi massmedia när vår kunskap åsidosätts? Dessa frågor vill vi diskutera utifrån erfarenheter bland nordiska historiker.

Combination of Tevatron Searches for the Standard Model Higgs Boson in the W+W- Decay Mode
- 2010
-
In: Physical Review Letters. - 0031-9007 .- 1079-7114. ; 104:6, s. 061802-
-
Journal article (peer-reviewed)abstract
- We combine searches by the CDF and D0 Collaborations for a Higgs boson decaying to W+W-. The data correspond to an integrated total luminosity of 4.8 (CDF) and 5.4 (D0) fb(-1) of p (p) over bar collisions at root s = 1.96 TeV at the Fermilab Tevatron collider. No excess is observed above background expectation, and resulting limits on Higgs boson production exclude a standard model Higgs boson in the mass range 162-166 GeV at the 95% C.L.
