Algorithms for Massive MIMO uplink detection are typically based on a centralized approach, by which baseband data from all antenna modules need to be routed to a central node for further processing. In the case of Massive MIMO, where hundreds or thousands of antennas are expected in the base-station, such architecture requires high interconnection bandwidth between antennas and the central node.
Previous open-label trials testing glial cell line-derived neurotrophic factor (GDNF) family ligands in Parkinson disease have shown promising clinical effects. However, in placebo-controlled trials, the treatments have failed. A new randomized placebo-controlled trial of intraputamenal delivery of GDNF designed to resolve this conundrum has again failed to do just that.
Most migrating birds need to stopover in between flights in order to refuel. Lately, additional purposes of stopover have been suggested, including physiological recovery from metabolically demanding migratory flight. One apparently unavoidable, but harmful physiological effect of migratory flight is increased oxidative damage to lipids and proteins. We here, for the first time, tested whether mig
Two different learning models for a teachable agent were tested with respect to perceived intelligence, the protégé effect, and learning in Swedish grade 5 and 6 students. A strong positive correlation was found between perceived intelligence and the protégé effect, but no significant differences were found between the two different implementations of the learning algorithm. The results suggest th
Lateralized behaviours are widespread among the animals, including insects with their miniature brains, perhaps being a way of maximising neural capacity (reviewed in [1,2]). However, evidence for functional asymmetries in the neural circuitry itself is scarce. Here, using bilateral simultaneous recordings from the ex vivo nervous system of desert locusts, we show that the neural control of their
Introduction: ECG-derived vectorcardiography (VCG) has diagnostic and prognostic value in various diseases. Hypertrophic cardiomyopathy (HCM), a genetic disease with unexplained left ventricular hypertrophy, is one of the most common causes of sudden cardiac death (SCD) in young persons. Genotype positive status is associated with increased risk of systolic dysfunction, heart failure, and (SCD). H
Pseudomonas aeruginosa airway infection is common in cystic fibrosis (CF), a disease also characterized by abundant extracellular DNA (eDNA) in the airways. The eDNA is mainly derived from neutrophils accumulating in the airways and contributes to a high sputum viscosity. The altered environment in the lower airways also paves the way for chronic P. aeruginosa infection. Here, we show that mice wi
UNLABELLED: BACKGROUND AND AIMS: The aim of the present investigation was to examine the anti-wasting effects of theophylline (a methylxantine present in tea leaves) on a rat model of cancer cachexia.METHODS: The in vitro effects of the nutraceuticals on proteolysis were examined on muscle cell cultures submitted to hyperthermia. Individual muscle weights, muscle gene expression, body composition
Objective: Genome-wide association studies (GWAS) have been successful at identifying associations with stroke and stroke subtypes, but have not yet identified any associations solely with small vessel stroke (SVS). SVS comprises one quarter of all ischemic stroke and is a major manifestation of cerebral small vessel disease, the primary cause of vascular cognitive impairment. Studies across neuro
A 67-year-old, previously fit, woman presented with a history of rectal bleeding.Per rectum examination revealed alow rectal mass, which on endoscopy wasdemonstrated to be submucosal. MR rectumconfirmed a 5 cm rectal mass displacing therectum anteriorly. Chest x-ray and abdominalCT did not reveal any metastatic disease. Biopsies were consistent with high grade gastrointestinal stromal cell tumour
Large landed estates often have an interesting history, worth digging into. Labour hiring is usually regarded as the capitalist relation of production. A classic study from the 1980s of salad farms in California, United States of America (USA), showed that farm workers were recruited from highly segmented niches in the labour market, with illegal immigrants at the lower rungs doing the most tediou
The environment contains different forms of ecological noise that can reduce the ability of animals to detect information. Here, we ask whether animals adapt their behavior to either exploit or avoid areas of their environment with increased dynamic visual noise. Threespined sticklebacks (Gasterosteus aculeatus) were immersed in environments with a simulated formof naturally occurring visual noise
Lys34 of the conserved translation elongation factor P (EF-P) is post-translationally lysinylated by YjeK and YjeA--a modification that is critical for bacterial virulence. Here we show that the currently accepted Escherichia coli EF-P modification pathway is incomplete and lacks a final hydroxylation step mediated by YfcM, an enzyme distinct from deoxyhypusine hydroxylase that catalyzes the final
Background: Adults with complex congenital heart disease (CHD) have reduced aerobic capacity and impaired muscle function. We therefore hypothesized that patients have a lower skeletal muscle mass and higher fat mass than controls. Methods: Body composition was examined with full body Dual-Energy x-ray Absorptiometry (DXA) in 73 patients with complex CHD (mean age 35.8 ± 14.3, women n = 22) and 73
The motivations prompting China's dramatic increase in outward foreign direct investment (OFDI) are not always clear, especially regarding OFDI by state-owned enterprises (SOEs) in energy and natural resources. First, both commercial and governmental interests are intertwined, although not necessarily in lock-step. Chinese SOEs listed in the West may worry about the reputational risks to their glo
One of the reasons to subsidise public transport is to improve the mobility of low-income groups by providing affordable public transport; however, the literature describes a situation whereby those with a low income are unable to afford the cheapest tickets per trip, i.e. travelcards, as they usually require a considerable up-front cost. In this study, we use a large dataset from the Swedish Nati
Nitric oxide (NO) exerts its vasodilator and antiaggregatory effects through activation of soluble guanylate cyclase and the consequent increase in the concentration of cGMP in target cells. We conducted this study in order to evaluate relationships between intraplatelet cGMP levels and risk factors for atherosclerosis in middle aged subjects. Intraplatelet cGMP was determined by radioimmunoassay
Lebanon is an eastern Mediterranean country inhabited by approximately four million people with a wide variety of ethnicities and religions, including Muslim, Christian, and Druze. In the present study, 926 Lebanese men were typed with Y-chromosomal SNP and STR markers, and unusually, male genetic variation within Lebanon was found to be more strongly structured by religious affiliation than by ge
