This paper presents an energy-efficient sorted QR decomposition (SQRD) processor for 3GPP LTE-Advanced (LTE-A) systems. The processor adopts a hybrid decomposition scheme to reduce computational complexity and provides a wide-range of performance complexity trade-offs. Based on the energy distribution of spatial channels, it switches between the brute-force SQRD and a low-complexity group-sort QR-
Islands of innovation as magnetic centres of star scientists? Empirical evidence on spatial concentration and mobility patterns, Regional Studies. Drawing on the results of a survey of 720 ‘star scientists’, this paper seeks to analyse the role of islands of innovation in the United States and Europe in providing educational and employment opportunities for such scientists and in attracting intern
PURPOSE A binational, population-based treatment protocol was established to prospectively treat and follow patients with seminomatous testicular cancer. The aim was to standardize care for all patients with seminoma to further improve the good results expected for this disease. PATIENTS AND METHODS From 2000 to 2006, a total of 1,384 Norwegian and Swedish patients were included in the study. Trea
Abstract Patients' satisfaction is an important outcome measure in reconstructive surgery and quality assurance is today central in the clinical practice. The aim of this study was to evaluate the patients' satisfaction with the process and final result after reconstruction for congenital microtia. A questionnaire was designed and sent to 78 patients who had undergone unilateral ear reconstruction
In the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) trial, combined ezetimibe (10 mg) and simvastatin (40 mg) decreased low-density lipoprotein cholesterol levels by 50% and ischemic cardiovascular event (ICE) risk by 22% compared to placebo. A larger decrease in ICE risk might have been expected for the degree of lipid-lowering observed. This analysis investigated relations between changes
Conditional cash transfers (CCTs) are often being promoted for their simultaneous advantages of short-term income protection and long-term human capital investments. Yet, existing evaluations have largely failed to test the underlying programme theory, and few empirical case studies have explored inherent contradictions and ambiguous consequences of this hybrid approach. To further understand the
Prior studies, utilizing interview-based assessments, suggest that most of the genetic risk factors for drug abuse (DA) are non-specific with a minority acting specifically on risk for abuse of particular psychoactive substance classes. We seek to replicate these findings using objective national registry data.
Nontypeable Haemophilus influenzae (NTHi) is one of the main aetiologies of childhood bacterial infections as well as exacerbations in COPD patients. Currently, no licensed NTHi vaccine exists. In the present study, we evaluated the potential of the conserved and ubiquitous surface protein Haemophilus Protein F (PF) as a vaccine candidate. Our results show that incubation of NTHi with anti-PF anti
The Precambrian inliers of the Anti Atlas belt located at the southern part of Morocco contain numerous mafic dyke and sill swarms thought to represent the erosional remnants of Proterozoic Large Igneous Provinces (LIPS). As part of a continuing research campaign to date and characterize these LIPs, four dykes have been dated by the U-Pb TIMS (Thermal Ionization Mass Spectrometry) method on baddel
We report a method for making horizontal wrap-gate nanowire transistors with up to four independently controllable wrap-gated segments. While the step up to two independent wrap-gates requires a major change in fabrication methodology, a key advantage to this new approach, and the horizontal orientation more generally, is that achieving more than two wrap-gate segments then requires no extra fabri
Histidine rich, unstructured peptides adsorb to charged interfaces such as mineral surfaces and microbial cell membranes. At a molecular level, we investigate the adsorption mechanism as a function of pH, salt, and multivalent ions showing that (1) proton charge fluctuations are - in contrast to the majority of proteins - optimal at neutral pH, promoting electrostatic interactions with anionic sur
The role of community based dynamics in successful agrarian development is considered through comparing two neighbouring villages in Ghana, with similar agro-ecological conditions and market access: one, Gyedi, is a religious community and the other, Apaa, is not. While the direct role of religion in promoting agrarian development is limited, interaction with extension staff in Gyedi enables farme
This paper complements the other papers in the Lancet Series on midwifery by documenting the experience of low-income and middle-income countries that deployed midwives as one of the core constituents of their strategy to improve maternal and newborn health. It examines the constellation of various diverse health-system strengthening interventions deployed by Burkina Faso, Cambodia, Indonesia, and
Accurate characterization of the astrometric errors in the forthcoming Gaia catalogue is essential for making optimal use of the data. Using small-scale numerical simulations of the astrometric solution, we investigate the expected spatial correlation between the astrometric errors of stars as function of their angular separation. Extrapolating to the full-scale solution for the final Gala catalog
The aging of Western populations is expected to result in increasing occurrence of aortic stenosis (AS), but data are limited. Recent studies have reported declining incidence and mortality for other major heart diseases. We aimed to study temporal trends in the incidence and prognosis for AS in Sweden.
Mobility growth poses considerable challenges to city planners around the world, as it entails problems of congestion, air pollution, and accidents. Many cities have thus sought to increase the share of sustainable transport, and specifically travel by bicycle. However, it appears that measures to foster cycling are often implemented on an ad hoc basis, lacking strategic focus and a more profound
