Species diversity is important for a range of ecosystem processes and properties, including the resistance to single and multiple stressors. It has been suggested that genetic diversity may play a similar role, but empirical evidence is still relatively scarce. Here, we report the results of a microcosm experiment where four strains of the marine diatom Skeletonema marinoi were grown in monocultur
PURPOSE OF REVIEW: The clinical and inflammatory heterogeneity in asthma constitutes a major challenge for improved treatment. This review describes the nature of the inflammatory complexity and how it can be decoded to yield improved disease understanding and personalized treatment. The focus is on the difficult task of revealing the immunological complexity as it occurs inside diseased patient t
The Swedish model has been seen as way to combine rapid growth with small wage gaps. The solidaristic wage policy negotiated by peak organizations between 1956 and 1983 was designed to induce restructuring by reducing wage differences across the economy. Several authors have linked this to decreased wage dispersion and rapid structural change, especially during the 1960s. However, there is disagre
The Tile Calorimeter is the hadron calorimeter covering the central region of the ATLAS experiment at the Large Hadron Collider. Approximately 10,000 photomultipliers collect light from scintillating tiles acting as the active material sandwiched between slabs of steel absorber. This paper gives an overview of the calorimeter’s performance during the years 2008–2012 using cosmic-ray muon events an
Flying animals need continual sensory feedback about their body position and orientation for flight control. The visual system provides essential but slow feedback. In contrast, mechanosensory channels can provide feedback at much shorter timescales. How the contributions from these two senses are integrated remains an open question in most insect groups. In Diptera, fast mechanosensory feedback i
Temperature often affects maternal investment in offspring. Across and within species, mothers in colder environments generally produce larger offspring than mothers in warmer environments, but the underlying drivers of this relationship remain unresolved. We formally evaluated the ubiquity of the temperature–offspring size relationship and found strong support for a negative relationshipacross a
Riodinidae is a highly diverse buttery family with the majority of its genera restricted to the Neotropics and, despite previous efforts, its higher systematics remains unresolved. Here, we propose a novel phylogenetic hypothesis, based on a comprehensive sample of riodinids, primarily from the Neotropics, covering 67% of all genera and all of the major lineages. We sequenced nine molecular marke
Although grade inflation is unfair and may imply inefficient allocation of human resources, current knowledge of grade inflation effects on individual outcomes is scarce. One explanation is probably the challenge of measuring and estimating causal grade inflation effects. This study examines the consequences of grade inflation at the upper secondary education level on enrolment in higher education
We present the microscopic model for collective effects, built on string–string interactions (string shoving and rope hadronization), recently implemented in the PYTHIA8 and DIPSY event generators. Rope hadronization is shown to give a good description of strangeness enhancement across pp, pA and AA collision systems, while string shoving qualitatively describes the ridge observed in pp collisions
In trying to understand why archaeology is so strongly associated with the method of excavation, this paper examines different relationships between excavation, archaeology, archaeologists and modern society.
Amyloid plaques and neurofibrillary tangles (NFTs) in the brain are the neuropathological hallmarks of Alzheimer's disease (AD). Amyloid plaques are composed of β-amyloid peptides (Aβ), while NFTs contain hyperphosphorylated tau proteins. Patients with familial AD who have mutations in the amyloid precursor protein (APP) gene have either increased production of Aβ or generate more aggregation-pron
Dietary sphingomyelin (SM) undergoes sequential cleavage to ceramide and sphingosine in the intestine. A distinctive intestinal sphingomyelinase (SMase) with alkaline pH-optimum was earlier identified by us. The activity was highest in middle and lower small intestine, but its role in SM digestion has not been clarified. In this study we examined the extension and capacity of SM digestion in vivo.
Den aisopiska fabeln etablerades som genre i den grekiska antiken och nådde Skandinavien under medeltiden. I svensk kultur upplevde fabeln en storhetstid under den tidigmoderna epoken (1500–1800). Monografin Fabelbruk i svensk tidigmodernitet. En genrehistorisk studie tar ett helhetsgrepp om fabelgenrens historia i Sverige under denna 300-årsperiod. I dialog med ny internationell fabel- och genrefEstablished as a genre in Greek antiquity, the Aesopic fable reached Scandinavia during the Middle Ages. In Sweden, the fable experienced its glory days during the early modern epoch (1500–1800). The monograph Fabelbruk i svensk tidigmodernitet. En genrehistorisk studie [Usage of Fable in Swedish Early Modernity. A Genre History] takes a comprehensive look at the history of fable in Sweden during
Background: Metalworkers are exposed to many sensitizing and irritant substances. There are no published data on contact allergy in this population in the Baltic countries. Objectives: To detect skin symptoms related to occupational exposure and to describe the reactivity pattern to the European baseline series in workers from two metal plants in Lithuania. Methods: In this cross-sectional study 1
