Partly overlapping feathers form a large part of birds’ wing surfaces, but in many species the outermost feathers split, making each feather function as an independent wing. These feathers are complex structures that evolved to fulfil both aerodynamic and structural functions. Yet relatively little is known about how the profile shape and microstructures of feathers impact aerodynamic performance.
The Gaussian β-ensemble is a real n-point configuration {xj}n1 picked randomly with respect to the Boltzmann factor e− β 2 Hn, where Hn = ∑i≠j log |xi−1xj| + n ∑ni=112 xi2. It is well known that the point process {xj }n1 tends to follow the semicircle law σ (x) = 21π√(4 − x2 )+ in certain average senses. A Fekete configuration (minimizer of Hn) is spread out in a much more uniform way in the inter
The article examines Europeanisation processes at the Spanish University of Valladolid (UVa) in the years around Spain’s adhesion to the European Communities in 1986. This event has often been seen as key to the Spanish transition to democracy, which had begun after the death of Francisco Franco in 1975. Drawing on a variety of source materials, the article shows that Europeanisation at the UVa in
Background: Natural selection can be a potent contributor to speciation, but how exactly this occurs remains unclear. Studying behavioral isolation and the divergence of mating behaviors among multiple isolated populations can help uncover the importance of divergent adaptation in the evolution of reproductive isolation. Here, we utilize common-garden reared virgin Bahamas mosquitofish (Gambusia h
In this editorial, the author states that the importance of casting off blinders applies to topics and disciplines as much as to individuals. There is no disagreement in psychology that we are mostly ignorant of the various neurophysiological and cognitive substrates and limitations of our conscious experience, but there are other background processes that determine what, how, and even whether we
This chapter critically examines the structural forces shaping the emergence and spread of Emerging Infectious Diseases (EIDs), with a particular focus on avian influenza and the poultry supply chain. Moving beyond conventional epicenter thinking, which attributes disease emergence to specific geographic locations, we argue that EIDs should be understood within broader ecological, economic, social
Natural resource extraction often takes place in locations where communities are not financially well-off and where historically marginalized groups reside. This paper contributes to the policy debate by revealing how corporate social licence tactics enable a model of corporate-community manipulation which is similar across different geographical contexts. Original data gathered between 2016 and 2
The interest in urban tourism has increased lately, both among visitors and in research. In new urban tourism, some significant tendencies are identified: blurring traditional categories of tourists, changes in tourism culture, and spatial change. These tendencies are based on structural change and relevant for understanding current urban destination development. In short, a large variety of visit
The subfamily Stiriinae (Lepidoptera, Noctuidae) is a group of ∼160 described moth species, ∼91% of which occur in the Nearctic, with species diversity centered in the deserts, grasslands, and adjacent foothills of the mountain ranges of Mexico. We infer the first species-level phylogeny for the subfamily using 8 protein-coding genes. While some lineages are primarily leaf or flower feeders, the m
The evolution of male courtship rituals has traditionally been attributed to female mate selection, but may also hinge on male investment strategies in sexually cannibalistic species. In many spiders, males perform energetically costly courtship rituals to increase acceptance by females and minimise the risk of sexual cannibalism. However, due to sperm competition, males may invest less energy whe
The North-Western Sahara Aquifer System (NWSAS) shared by Libya, Tunisia, and Algeria is one of North Africa’s biggest nonrenewable groundwater storage systems. The management of its resources in a sustainable way will be central to regional stability, food security, and climate resilience. This book chapter discusses how transboundary cooperation along the NWSAS has evolved through facilitation b
Originally published in 1887 by researcher Richard Hodgson and amateur magician Samuel John Davey, The Mal-Observation Report is a classic of psychical research that remains startlingly relevant to modern psychology. This 292-page volume brings together two seminal papers that revealed how performance magic methods can be used to reveal surprising limits and eccentricities of human minds.In "The P
I följande examensarbete undersöks den morfologiska kustlinjeutvecklingen vid den västra stranden i Ystad Sandskog med fokus på kusterosion och längsgående sedimenttransport. Kuststräckan är historiskt och fortsatt erosionsutsatt och ligger i nära anslutning till bebyggelser, infrastruktur och naturreservatet Sandskogen. För att motverka kustens tillbakadragning har flera kustskyddsåtgärder implemThis master thesis investigates the morphological shoreline development at the western beach of Ystad Sandskog, with a focus on coastal erosion and longshore sediment transport. The coastline is affected by erosion and is located close to residential areas, infrastructure and the nature preserve Sandskogen. Several coastal protection measures have been implemented to prevent ongoing shoreline retr
For over a century, screen narratives set in Greenland have used crime to re-flect and rework tensions between law, society, and place. This article examines a broad selection of films and television series set or shot in Greenland to trace how crime is used to negotiate questions of justice, identity, and power. Through a place-based approach informed by location studies, it shows how spatial rep
The stability of therapeutic proteins is crucial for maintaining their efficacy and safety. Misfolded or aggregated proteins can accelerate aggregation by a seeding effect, altering protein stability and interactions. Heat-induced aggregates can pose a risk because they can have perturbed structures that expose aggregate-prone regions. This study explored seeding by heat-induced protein aggregates
Monitoring and characterizing melt pool dynamics in additive manufacturing is essential for understanding complex thermal and material behaviors that govern layer formation. Melt pool characteristics, such as size, shape, and dynamics, directly influence microstructure evolution, mechanical properties, and dimensional accuracy of the printed part. Therefore, accurate and efficient methods for melt
This editorial reflects on recent developments at Historical Life Course Studies over the past two years. It highlights the successful completion of two special issues, including one on infant mortality and another on histories of health published in honour of Angélique Janssens. The editorial notes encouraging trends in submissions, citations, and online visibility, and announces an upcoming spec
