The trapping of organic matter within plant patches in the channels of the Okavango Delta : a matter of quality

The role of in-stream aquatic vegetation as ecosystem engineers in the distribution of organic matter was investigated in the Okavango Delta, one of the world’s largest oligotrophic wetlands. The Okavango channel beds are covered up to 50% with submerged macrophyte patches. By accumulating and concentrating organic matter in the sediments below the patches, macrophytes are likely able to locally f

Performance Characterization of a Real-Time Massive MIMO System with LOS Mobile Channels

The first measured results for massive multiple input, multiple-output (MIMO) performance in a line-of-sight (LOS) scenario with moderate mobility are presented, with 8 users served in real-time using a 100 antenna base Station (BS) at 3.7 GHz. When such a large number of channels dynamically change, the inherent propagation and processing delay has a critical relationship with the rate of change,

Sweden, Inc and the campaign to sell JAS-Gripen to the Swiss electorate

In January 2014, it emerged that manufacturer Saab had provided financial backing to the “yes” campaign for a referendum on whether Switzerland should purchase 22 JAS-Gripen aircraft. Although the funds were immediately returned, a second story broke in February revealing the detailed involvement of the Swedish Embassy in the broader coordination of a public diplomacy campaign to support the “yes”

Examining possible neutron-halo nuclei heavier than Mg 37

The even-Z odd-N neutron-halo nuclei, which are the lightest neutron-halo nuclei heavier than Mg37, are explored by studying the shell structure unique in weakly bound neutrons for spherical or deformed shapes. It is pointed out that due to the narrowed N=50 spherical energy gap and a few resulting close-lying neutron one-particle levels, 1g9/2, 3s1/2, and 2d5/2, for spherical shape, nuclei with s

Emerging affinity-based proteomic technologies for large-scale plasma profiling in cardiovascular disease

Plasma biomarkers that reflect molecular states of the cardiovascular system are central for clinical decision making. Routinely used plasma biomarkers include troponins, natriuretic peptides, and lipoprotein particles, yet interrogate only a modest subset of pathways relevant to cardiovascular disease. Systematic profiling of a larger portion of circulating plasma proteins (the plasma proteome) w

Factors driving the use of dermoscopy in Europe : a pan-European survey

BACKGROUND: When used correctly, dermoscopy is an essential tool for helping clinicians in the diagnosis of skin diseases and the early detection of skin cancers. Despite its proven benefits, there is a lack of data about how European dermatologists use dermoscopy in everyday practice.OBJECTIVES: To identify the motivations, obstacles and modifiable factors influencing the use of dermoscopy in dai

Impacts of land use on climate and ecosystem productivity over the Amazon and the South American continent

The Amazon basin is characterized by a strong interplay between the atmosphere and vegetation. Anthropogenic land use and land cover change (LULCC) affects vegetation and the exchange of energy and water with the atmosphere. Here we have assessed potential LULCC impacts on climate and natural vegetation dynamics over South America with a regional Earth system model that also accounts for vegetatio

36 h fasting of young men influences adipose tissue DNA methylation of LEP and ADIPOQ in a birth weight-dependent manner

Background: Subjects born with low birth weight (LBW) display a more energy-conserving response to fasting compared with normal birth weight (NBW) subjects. However, the molecular mechanisms explaining these metabolic differences remain unknown. Environmental influences may dynamically affect epigenetic marks, also in postnatal life. Here, we aimed to study the effects of short-term fasting on lep

Survival and functional recovery of transplanted human dopaminergic neurons into hemiparkinsonian rats depend on the cannula size of the implantation instrument

Promising therapeutic strategies for neurodegenerative diseases such as Parkinson's disease include replacement of lost striatal dopaminergic neurons by grafting of embryonic mesencephalic cells. However, the poor survival of the transplanted tissue still limits transplantation of these cells into the human brain in a larger number of patients. We addressed the question, if the diameter of the tra

The Paleozoic Origin of Enzymatic Lignin Decomposition Reconstructed from 31 Fungal Genomes

Wood is a major pool of organic carbon that is highly resistant to decay, owing largely to the presence of lignin. The only organisms capable of substantial lignin decay are white rot fungi in the Agaricomycetes, which also contains non–lignin-degrading brown rot and ectomycorrhizal species. Comparative analyses of 31 fungal genomes (12 generated for this study) suggest that lignin-degrading perox

Linking Swedish health data registers to establish a research database and a shared decision-making tool in hip replacement

Background: Sweden offers a unique opportunity to researchers to construct comprehensive databases that encompass a wide variety of healthcare related data. Statistics Sweden and the National Board of Health and Welfare collect individual level data for all Swedish residents that ranges from medical diagnoses to socioeconomic information. In addition to the information collected by governmental ag
