Massive multiple input multiple output (MIMO) is a revolutionary communication technique, where large numbers of antennas are employed at the base stations to increase the spectral efficiency, reliability and data rate of the system. Moreover, in multi-user MIMO (MU-MIMO) multiple users can be served by the base stations on the same time-frequency resource. Distributed antenna system (DAS) is a fo
During the late Eocene there was an enigmatic enhancement in the flux of extraterrestrial material to Earth. Evidence comes from sedimentary 3He records indicating an increased flux of interplanetary dust during ca. 2 Myr, as well as two very large impact structures, Popigai (100 km diameter) and Chesapeake Bay (40–85 km), that formed within 10–20 kyr at the peak of the 3He delivery. The Massignan
Biogenic volatile organic compounds (BVOCs) play an important role in the chemistry of the troposphere, especially in the formation of tropospheric ozone (O3) and secondary organic aerosols (SOA). Ecosystems produce and emit a large number of BVOCs. It is estimated on a global scale that approximately 90% of annual BVOC emissions are from terrestrial sources. In this study, measurements of BVOCs w
Background: Novel phosphorylated-tau (p-tau) blood biomarkers (e.g., p-tau181, p-tau217 or p-tau231), are highly specific for Alzheimer’s disease (AD), and can track amyloid-β (Aβ) and tau pathology. However, because these biomarkers are strongly associated with the emergence of Aβ pathology, it is difficult to determine the contribution of insoluble tau aggregates to the plasma p-tau signal
Background Influenza and other respiratory viruses promote Streptococcus pneumoniae proliferation in the upper respiratory tract. We sought to investigate for what we believe is the first time, the effect of intranasal live attenuated influenza vaccine (LAIV) on nasopharyngeal S pneumoniae density in a low-income to middle-income country population with high pneumococcal carriage rates. Methods I
IMPORTANCE: The availability of behavior therapy for individuals with Tourette syndrome (TS) and chronic tic disorder (CTD) is limited.OBJECTIVE: To determine the efficacy and cost-effectiveness of internet-delivered exposure and response prevention (ERP) for children and adolescents with TS or CTD.DESIGN, SETTING, AND PARTICIPANTS: This single-masked, parallel group, superiority randomized clinic
Design is often described as a profession where the result of the work is future oriented. Herbert Simon defined it as work that aims at “changing existing situations into preferred ones” . This may refer to a design process where the result can be very unpredictable even if the goal is thoroughly outlined. David Pye has portrayed this performance as “workmanship of risk” which differs from “workm
Case endings are an important marker of fuṣḥā but are by most native speakers considered complicated and difficult. They typically appear only sporadically even in the most formal speech styles. There has been relatively little academic interest in the use of case endings in speech. Research has been characterized by largely impressionistic accounts (Badawi 1973, Meiseles 1977) and more recently b
Background: Accurate referral of boys with suspected undescended testes (UDT) is of importance to preserve fertility and reduce risk of future testicular cancer. While late referral is well studied, there is less knowledge about incorrect referrals, hence, referral of boys with normal testes. Objective: To evaluate the proportion of UDT referrals that did not lead to surgery or follow-up, and to a
Bakgrund: Behandling av komplicerade analfistlar försätter att vara en stor utmaning. Tidiga studier på anal fistelplugg (AFP) visade att högt andel av patienter blir bra men senare har man rapporterad väldig varierande behandlingsframgång (13-100%) för uppföljningstider på 6-24 månader. Kunskap om de morfologiska fynd som kan relateras till framgångsrik eller misslyckad operationsresultat efter ABackground: The treatment of complex anal fistulae remains a therapeutic challenge. Early anal fistula plug (AFP) studies showed high success rates, while later reports demonstrated success rate of 13-100% at usual follow-up of 6-24 months. Very little is known about morphological findings related to success and failure of the AFP, especially if three-dimensional (3D) endoanal ultrasound (EAUS) is
One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. The techniques are rapid, sensitive, efficient, and suitable even for analyte
The main goal of my studies was obtaining bulk acoustofluidic devices able to achieve high energy density inside a water-filled cavity. This led us to explore the interplay of sound and thermal effects more in details. Hence, this thesis covers both thermoacoustic effects in Bulk Acoustic Wave devices and a revisited approach for designing them, focusing on achieving good performance. Thermoacoust

BackgroundHeart failure (HF) and arterial hypertension (AH) are strongly associated with obesity, with a linear relationship to increasing body mass index (BMI). However, some individuals with obesity do not exhibit signs of HF or AH.PurposeThis study aimed to compare, for the first time in a large population-based cohort, individuals with obesity who have normal left ventricular function and remo
BACKGROUND: HYPO-RT-PC is a phase 3 trial comparing ultra-hypofractionated and conventionally fractionated radiotherapy in intermediate-to-high-risk localised prostate cancer. This 10-year update reports long-term efficacy and toxicity outcomes.METHODS: In this open-label, randomised, phase 3, non-inferiority trial done in ten centres in Sweden and two in Denmark, we recruited men aged 75 years or
Kungahälla was the southernmost town in medieval Norway. The site, now in Sweden, is about 2 kmwest of today's Kungälv. Kungahälla occupies a significant place in the oldest written sources, the Norse sagas, where we have a glimpse of the important role that the town played in early medieval Norwegian society. Opinions have been divided as to how far back this role can he taken, but there is no ce

Background: Exposure and Response Prevention (ERP) is a form of behavioural therapy for tics; however, its effectiveness remains uncertain. We aimed to evaluate the effectiveness of internet-delivered, therapist-supported, and parent-assisted ERP for treatment of tics in children and young people with Tourette syndrome or chronic tic disorder. Methods: This multicentre, parallel group, single-blin
Frågan om vilken verkan ändrade förhållanden har i en avtalsrelation har alltid varit ett av kontrakträttens mest uppmärksammade problem. Vid långvariga avtal blir utvecklingen inte sällan annan än vad parterna kunnat förutse vid avtalets ingående. Ett långvarigt avtal kan sålunda under en stor del av giltighetstid ha varit förmånligt för bägge parter, men sedan på grund av ändrade förhållande bliThe significance of changed conditions for contractual obligations and liabilities has always been one of the most debated contract law issues. In long-term agreements it is often extremely difficult to forecast all possible effects of a contract due to the fact that conditions under which the contracting parties have entered into such contract may drastically change. The substance of a long-term
Uppsatsen tar sikte på att behandla sak- och associationsrättsliga aspekter inom ramen för en aktietransaktion, i synnerhet fokuseras på dispositioner såsom värdepapperslån (eng. securities lending) och blankning (eng. short selling). Det torde vara mycket svårt att föra en talan avseende att en aktieförvärvare skulle vara i ond tro och att denne därigenom inte gjort ett godtrosförvärv av en aktThe purpose of this paper is to examine a number of property- and corporate law aspects within the framework of a transaction of shares, targeting primarily dispositions such as securities lending and short selling. Since it ought to be difficult to bring a successful claim against a share purchaser, claiming that he was in bad faith while acquiring the shares and thus did not make an acquisitio
