Analytical dual-link MIMO channel model using correlated correlation matrices

Analytical Multiple-Input Multiple-Output (MIMO) models are often attractive due to their low complexity when analyzing possibilities and limitations in the system. In this paper we outline a a possible dual link extension of an analytical MIMO channel model and investigate its suitability based on measurements of a dual link MIMO scenario. The extension is based on the correlation matrix distance

Contact and isolation in hunter-gatherer language dynamics: evidence from Maniq phonology (Aslian, Malay Peninsula)

Maniq, spoken by 250-300 people in southern Thailand, is an undocumented geographical outlier of the Aslian branch of Austroasiatic. Isolated from other Aslian varieties and exposed only to Southern Thai, this northernmost member of the group has long experienced a contact situation which is unique in the Aslian context. Aslian is otherwise mostly under influence from Malay, and exhibits typologic

Bedöma smärta vid afasi

. Smärta efter stroke kan vara av olika typer och varierande svårighetsgrad . Personer med kommunikationsproblem kan behöva peka ut områdett för smärtan och med ansiktsuttryck visa hur svår smärtan upplevs eller ange smärtnivå på en skala.

MAGIC-type polymer gel for three-dimensional dosimetry: intensity-modulated radiation therapy verification.

A new type of polymer gel dosimeter, which responds well to absorbed dose even when manufactured in the presence of normal levels of oxygen, was recently described by Fong et al. [Phys. Med. Biol. 46, 3105-3113 (2001)] and referred to by the acronym MAGIC. The aim of this study was to investigate the feasibility of using this new type of gel for intensity-modulated radiation therapy (IMRT) verific

Development and implementation of a standardized care plan for carotid endarterectomy.

Carotid endarterectomy (CEA) is a standardized surgical procedure and is the third most common vascular surgical procedure in Sweden. To improve the quality of pre- and postoperative care for patients undergoing elective CEA, a standardized care plan (SCP) was developed and implemented during Spring of 2007 at a vascular clinic in Sweden. In order to spread light on obstacles and possibilities in

Planning Fixed to Flexgrid Gradual Migration: Drivers and Open Issues

Flexgrid technology has recently been presented as the most promising option for upgrading the currently operating fixed grid optical networks and extending their capacity to be able to deal with the massive traffic volumes forecast for the next decade. Although the current traffic is successfully supported on fixed grid networks, flexgrid technology brings features that are not offered by the fix

Bedside Point of Care Coagulation Testing for Individualized Antivitamin K Reversal: A Prospective Study

A delay in surgery due to laboratory abnormalities may increase mortality in patients with hip fracture. In order to optimize the logistics for urgent surgery in patients with hip fractures and anti-vitamin K treatment, individualized doses of a Prothrombin Concentrate were guided by a bedside whole blood prothrombin time test. Thirty patients with emergency hip fracture and preoperative anti-vit
