We consider a MIMO system where error-prone feedback from the receiver is used by the transmitter to select a single optimum antenna to transmit data. Such error-prone feedback is common in the bandwidth-limited real systems, and is in marked contrast with the idealizations assumed in the selection literature. We show how the signaling assignment, which maps the antenna indices to the codewords th

Objectives. To investigate autonomic dysfunction (AD) development in patients with primary SS (pSS) and the associations between AD and clinical, inflammatory and serological features of pSS. Methods. Twenty-seven patients with pSS, who had previously been evaluated for AD, were included in the study. The patients were studied at baseline and at follow-up by objective autonomic reflex tests (ARTs)

Thrombomodulin gene (THBD) is a critical cofactor in protein C anticoagulant system. THBD c.1418C>T polymorphism is reported to be associated with higher risk of primary venous thromboembolism (VTE) but its role in VTE recurrence is unknown. The aim of this study was to investigate the role of THBD polymorphism in VTE recurrence. THBD c.1418C>T polymorphism was genotyped by using Taqman polymerase

Complete endovascular arch replacement by in situ fenestration technique requires maintenance of cerebral perfusion during the fenestration procedure by an extracorporeal femoral-carotid bypass. The bypass has the disadvantages of being invasive, requiring a pump and shunting blood extracorporeally. This report describes bench testing and an in vivo experimental animal setup with an endovascular,

Among the common complex diseases, hypertension has been particularly unlucky in the recent surge of positive results from genome-wide association studies. We summarize the evidence that would support continuing the effort in the hunt for a genetic basis for hypertension. The problems facing the genetic studies for hypertension are not unique, but phenotypic characterization, heterogeneity and hig

The aim of this work was to investigate the potential of a selection of household salts (NaCl) as a retrospective dosemeter for ionising radiation using optically stimulated luminescence (OSL). The OSL-response of five brands of salt to an absorbed dose in the range from 1 mGy to 9 Gy was investigated using a Risø TL/OSL-15 reader and a (60)Co beam, allowing low dose-rate irradiations. The salt wa

Popular Abstract in Swedish Prosodi och intonation är viktiga delar i det mänskliga talet. I system för text-till-talomvandling och automatisk taligenkänning måste prosodiska modeller inkluderas för att uppnå acceptabla resultat. Denna avhandling bidrar till modelleringen av svensk prosodi ur lexikalt och akustiskt perspektiv. Tre aspekter av lexikal modellering av prosodi studeras. Vi skisserar Prosody and intonation are very important ingredients of human speech. In speech technology, text-to-speech (TTS) and automatic speech recognition (ASR) systems must incorporate prosodic models in order to reach acceptable performances. We contribute to the modelling of Swedish prosody in a speech technology context from lexical and acoustic angles. Three aspects of lexical prosodic modelling are

Alpha 1-antichymotrypsin (ACT) inhibits chymotrypsin-like enzymes, particularly neutrophil cathepsin G. Moreover, ACT in its native form suppresses chemotaxis of neutrophils and decreases neutrophil production of superoxide radicals. We recently showed that Moraxella catarrhalis ubiquitous surface protein (Usp) A1 is able to specifically bind ACT in the context of a novel virulence mechanism. In t
