EU missions and operations: practices of learning lessons in the CSDP
Kreativitet och ekonomi : värden och dilemman i dataspelsbranschen
I artikeln studeras spelutvecklares upplevelser av sitt arbete och då särskilt i relation till föreställningar om kreativa och ekonomiska ideal. Artikeln är baserad på en analys av semistrukturerade intervjuer med spelutvecklare i svenska dataspelsbolag. Genom begreppet ’relational work’ belyses spänningen mellan passion för arbetet och dess ekonomiska villkor, och hur gränserna mellan vad som ans
Conclusion: learning and contestation in EU foreign and security policy
Microbial resilience to drying-rewetting is partly driven by selection for quick colonizers
Rewetting dry soil induces enormous changes in microbial growth and biogeochemistry. Upon drying-rewetting (D/RW), bacteria have been shown to exhibit two different responses: (1) a more resilient response where bacteria start growing immediately with a quick recovery after rewetting and (2) a less resilient response where there is a pronounced lag-period before bacterial growth starts to increase
Controls on carbon cycling in tropical soils from the Amazon to the Andes : the influence of climate, plant inputs, nutrients and soil organisms
Hydrogen-atom and oxygen-atom transfer reactivities of iron(
A series of iron(ii) complexes with the general formula [FeII(L2-Qn)(L)]n+ (n = 1, L = F−, Cl−; n = 2, L = NCMe, H2O) have been isolated and characterized. The X-ray crystallographic data reveals that metal–ligand bond distances vary with varying ligand field strengths of the sixth ligand. While the complexes with fluoride, chloride and water as axial ligand are high spin, the acetonitrile-coordin
Vesicles Balance Osmotic Stress with Bending Energy That Can Be Released to Form Daughter Vesicles
The bending energy of the lipid membrane is central to biological processes involving vesicles, such as endocytosis and exocytosis. To illustrate the role of bending energy in these processes, we study the response of single-component giant unilamellar vesicles (GUVs) subjected to external osmotic stress by glucose addition. For osmotic pressures exceeding 0.15 atm, an abrupt shape change from sph
Developmental disorders caused by haploinsufficiency of transcriptional regulators : a perspective based on cell fate determination
Many human birth defects and neurodevelopmental disorders are caused by loss-of-function mutations in a single copy of transcription factor (TF) and chromatin regulator genes. Although this dosage sensitivity has long been known, how and why haploinsufficiency (HI) of transcriptional regulators leads to developmental disorders (DDs) is unclear. Here I propose the hypothesis that such DDs result fr
Seg2Pose: Pose Estimations from Instance Segmentation Masks in One or Multiple Views for Traffic Applications
A system we denote Seg2Pose is presented which converts pixel coordinate tracks, represented by instance segmentation masks across multiple video frames, into world coordinate pose tracks, for road users seen by static surveillance cameras. The road users are bound to a ground surface represented by a number of 3D points and does not necessarily have to be perfectly flat. The system works with one
Great Tits Learn Odors and Colors Equally Well, and Show No Predisposition for Herbivore-Induced Plant Volatiles
Ability to efficiently localize productive foraging habitat is crucial for nesting success of insectivorous birds. Some bird species can use olfaction to identify caterpillar-infested trees by detection of herbivore induced plant volatiles (HIPVs), but these cues probably need to be learned. So far, we know very little about the process of olfactory learning in birds, whether insectivorous species
Physics of Organelle Membrane Bridging via Cytosolic Tethers is Distinct From Cell Adhesion
Tremendous progress has been made recently in imaging the contacts between intra-cellular organelles, which are thought to be mediated by soluble tethers. However, they are still difficult to study in cellulo, and reconstituting them in vitro is a standing challenge. Here we take a mimetic approach to study Giant unilamellar vesicles (GUVs) and supported lipid bilayers (SLBs) interacting via singl
Metal Pollution of the Solar White Dwarf by Solar System Small Bodies
White dwarfs (WDs) often show metal lines in their spectra, indicating accretion of asteroidal material. Our Sun is to become a WD in several gigayears. Here, we examine how the solar WD accretes from the three major small body populations: the main belt asteroids (MBAs), Jovian Trojan asteroids (JTAs), and trans-Neptunian objects (TNOs). Owing to the solar mass loss during the giant branch, 40% o
Genomic Signatures of Sexual Selection on Pollen-Expressed Genes in Arabis alpina
Fertilization in angiosperms involves the germination of pollen on the stigma, followed by the extrusion of a pollen tube that elongates through the style and delivers two sperm cells to the embryo sac. Sexual selection could occur throughout this process when male gametophytes compete for fertilization. The strength of sexual selection during pollen competition should be affected by the number of
Population Genomics of Wall Lizards Reflects the Dynamic History of the Mediterranean Basin
The Mediterranean Basin has experienced extensive change in geology and climate over the past six million years. Yet, the relative importance of key geological events for the distribution and genetic structure of the Mediterranean fauna remains poorly understood. Here, we use population genomic and phylogenomic analyses to establish the evolutionary history and genetic structure of common wall liz
Horismenus camobiensis (Hym. : Eulophidae), a new hyperparasitoid of Cotesia invirae (Hym.: Braconidae) in Opsiphanes invirae (Lep.: Nymphalidae) pupae
Horismenus camobiensis sp. nov. (Hymenoptera: Eulophidae), is described based on morphological, molecular and ecological data; this new species of chalcid wasp acts as hyperparasitoid of Opsiphanis invirae (Hübner, 1818) (Lepidoptera: Nymphalidae) in its parasitoid Cotesia invirae Salgado-Neto and Whitfield, 2019 (Hymenoptera: Braconidae). Diagnoses with morphological and molecular characters and
Why is it so difficult to study magnetic compass orientation in murine rodents?
A magnetic compass sense has been demonstrated in all major classes of vertebrates, as well as in many invertebrates. In mammals, controlled laboratory studies of mice have provided evidence for a robust magnetic compass that is comparable to, or exceeds, the performance of that in other animals. Nevertheless, the vast majority of laboratory studies of spatial behavior and cognition in murine rode
Magnon-phonon interaction and the underlying role of the Pauli exclusion principle
The magnon-phonon interaction is receiving growing attention due to its key role in spin caloritronics and the emerging field of acoustic spintronics. At resonance, this magnetoelastic interaction forms magnon polarons, which underpin exotic phenomena such as magnonic heat currents and phononic spin, but is mostly investigated using mesoscopic spin-lattice models. Motivated to integrate the magnon
Union Density in Norway and Sweden: Stability versus Decline
The aim is to explain why union density is not only considerably higher in the Ghent country Sweden than in non-Ghent Norway but also why it has declined much more in Sweden, in par-ticular among blue-collar workers. We show how changes to Swedish unemployment insurance in 2007–2013 were followed by a decline in union density and how white-collar unions were more successful than blue-collar unionsThe aim is to explain why union density is not only considerably higher in the Ghent country Sweden than in non-Ghent Norway but also why it has declined much more in Sweden, in particular among blue-collar workers. We show how changes to Swedish unemployment insurance in 2007–2013 were followed by a decline in union density and how white-collar unions were more successful than blue-collar unions
Rif2 protects Rap1-depleted telomeres from MRX-mediated degradation in Saccharomyces cerevisiae
Rap1 is the main protein that binds double-stranded telomeric DNA in Saccharomyces cerevisiae. Examination of the telomere functions of Rap1 is complicated by the fact that it also acts as a transcriptional regulator of hundreds of genes and is encoded by an essential gene. In this study, we disrupt Rap1 telomere association by expressing a mutant telomerase RNA subunit (tlc1-tm) that introduces m
