Rapid manoeuvre of fan worms (Annelida: Sabellidae) through tubes

Multiple variables determine the success of an escape response of an animal, and the rapidity of the escape manoeuvre is often the most important. Fan worms (Annelida: Sabellidae) can rapidly withdraw their tentacles, which are covered in heavily ciliated ramifications called pinnules, into their tubes to protect them from approaching threats. Here, we explore the dynamic and mechanistic features

A reality check on the GARCH-MIDAS volatility models

We employ a battery of model evaluation tests for a broad set of GARCH-MIDAS models and account for data snooping bias. We document that inferences based on standard tests for GM variance components can be misleading. Our data mining free results show that the gain of macro-variables in forecasting total (long-run) variance by GM models is overstated (understated). Estimation of different componen

New insights into the pathophysiology and therapeutic targets of asthma and comorbid chronic rhinosinusitis with or without nasal polyposis

Asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) or without (CRSsNP) are chronic respiratory diseases. These two disorders often co-exist based on common anatomical, immunological, histopathological, and pathophysiological basis. Usually, asthma with comorbid CRSwNP is driven by type 2 (T2) inflammation which predisposes to more severe, often intractable, disease. In the past two decad

På rätt sida av historien? Hbtq-rättigheter som global politik

Detta kapitel introducerar queera perspektiv på global politik med utgångspunkt i en diskussion om politisk mobilisering kring hbtq-frågor på nationell och transnationell nivå. Att diskutera global politik utifrån ett queerperspektiv handlar inte enbart om att ”lägga till” hbtq-personer. Snarare innebär en queer analys att kritiskt granska vissa av de antaganden kring säkerhet, makt och förtryck s

Investigating the Potential of Latent Heat in Hygroscopic Insulating Materials

Energy from buildings accounts for almost 40% of global energy-related carbon emissions. A way to reduce both energy consumption in buildings as well as their environmental impact is to use bio-based insulation materials such as cellulose, wood or hemp fiber insulation. Experiences from modern buildings built with a timber-frame structure and insulated with bio-based materials show that these buil

Utvärdering av hastighetssäkrade åtgärder på landsbygdsvägar

Detta arbete har utvärderat hastighetssäkrade åtgärders effekt på landsbygdsvägar genom att filma totalt 34 olika sådana åtgärder i södra Sverige och studera hastigheten av frigående bilar och tunga fordon när de passerar de olika åtgärderna.Varje plats har filmats med drönare och alla fordon har automatiskt spårats m.h.a. videoanalys. Därefter har frigående fordon identifierats och deras hastighe

Interaction between plasma phospholipid odd-chain fatty acids and GAD65 autoantibodies on the incidence of adult-onset diabetes : the EPIC-InterAct case–cohort study

Aims/hypothesis: Islet autoimmunity may progress to adult-onset diabetes. We investigated whether circulating odd-chain fatty acids (OCFA) 15:0 and 17:0, which are inversely associated with type 2 diabetes, interact with autoantibodies against GAD65 (GAD65Ab) on the incidence of adult-onset diabetes. Methods: We used the European EPIC-InterAct case–cohort study including 11,124 incident adult-onse

Flexible design in the stomatopod dactyl club

The stomatopod is a fascinating animal that uses its weaponized appendage dactyl clubs for breaking mollusc shells. Dactyl clubs are a well studied example of biomineralized hierarchical structures. Most research has focused on the regions close to the action, namely the impact region and surface composed of chitin and apatite crystallites. Further away from the site of impact, the club has lower

Probing the structure of χc1 (3872) with photon transition form factors

We propose studying the structure of the χc1(3872) axial vector meson through its γL∗γ→χc1(3872) transition form factor. We derive a light-front wave function representation of the form factor for the lowest cc¯ Fock state. We found that the reduced width of the state is well within the current experimental bound recently published by the Belle Collaboration. This strongly suggests a crucial role

Averaging of absorbed doses : How matter matters

Background: Dosimetry in radionuclide therapy often requires the calculation of average absorbed doses within and between spatial regions, for example, for voxel-based dosimetry methods, for paired organs, or across multiple tumors. Formation of such averages can be made in different ways, starting from different definitions. Purpose: The aim of this study is to formally specify different averagin

Customer value, customer engagement, and customer-based brand equity in the context of a digital payment app

Purpose:The objective of the paper is to explore the relationship among perceived quality value, hedonic value, social value, price value, customer engagement and customer-based brand equity using stimulus-organism-response (S-O-R), customer engagement and customer-perceived value theories for digital payment apps. In addition, the study examines the mediating role of customer engagement between c
