Fine structure of 4f–5d absorption spectra of MeF2-Yb3+ in the vacuum ultraviolet region under synchrotron excitation
Narrow dips were found in the excitation spectra of crystals of alkaline earth fluorides doped with ErF3 or/and YbF3. The positions of the dips are in good agreement with the positions of the narrow absorption lines Er3+, Yb3+ measured earlier. The absorption lines of the crystals were calculated from the excitation spectra. The observed dips in the excitation spectra are due to the absorption lin
The cranial anatomy and relationships of Cardiocorax mukulu (Plesiosauria: Elasmosauridae) from Bentiaba, Angola
We report a new specimen of the plesiosaur Cardiocorax mukulu that includes the most complete plesiosaur skull from sub-Saharan Africa. The well-preserved three-dimensional nature of the skull offers rare insight into the cranial anatomy of elasmosaurid plesiosaurians. The new specimen of Cardiocorax mukulu was recovered from Bentiaba, Namibe Province in Angola, approximately three meters above th

Compressed spike-triggered averaging in iterative decomposition of surface EMG
Background and Objective: Analysis of motor unit activity is important for assessing and treating diseases or injuries affecting natural movement. State-of-the-art decomposition translates high-density surface electromyography (HDsEMG) into motor unit activity. However, current decomposition methods offer far from complete separation of all motor units. Methods: This paper proposes a peel-off appr

Membrane permeability based on mesh analysis
The main function of a membrane is to control the exchange of matter between the surrounding regions. As such, accurate modeling of membranes is important to properly describe their properties. In many cases in both biological systems and technical applications, the membranes are composite structures where transport properties may vary between the different sub-regions of the membrane. In this wor
Numerical simulation of biomass gasification in fluidized bed gasifiers
Numerical simulation of biomass gasification in fluidized bed reactors faces several challenges including proper modeling of the physical and chemical processes involved in the gasification and numerical stiffness of the two-phase dense particle flow problem. In this paper, the multi-phase particle-in-cell (MP-PIC) model coupled with a recently developed distribution kernel method (DKM) and a new
Insights into the mechanisms of interaction between inhalable lipid-polymer hybrid nanoparticles and pulmonary surfactant
Pulmonary delivery of small interfering RNA (siRNA) using nanoparticle-based delivery systems is promising for local treatment of respiratory diseases. We designed dry powder inhaler formulations of siRNA-loaded lipid-polymer hybrid nanoparticles (LPNs) with aerosolization properties optimized for inhalation therapy. Interactions between LPNs and pulmonary surfactant (PS) determine the fate of inh
First-season growth and food of YOY pike (Esox lucius) are habitat specific within a lake
Piscivorous fish are important predators in aquatic systems and as such they can have far-reaching effects on ecosystem composition and function. These effects depend on piscivore predation rates and behaviour, and recruitment of young-of-the-year fish into piscivory can hereby govern ecosystem properties. Growth and recruitment can differ between water bodies due to e.g. general productivity, but

Using water vapour and N2 isotherms to unveil effects of SCMs on nanopores and evaluate hydration degree
Nanopores are critical for the durability of cement-based materials, but the refinement of these pores by SCMs is yet to have a clear understanding. This paper studied effects of the water–binder ratio, SCMs and the drying on the distribution of nanopores using water vapour and N2 sorption isotherms. Results show that data of water vapour sorption can be used for a practical evaluation of the hydr
Special issue: Media and health in every day life
The entanglements of media and health in everyday life
Just as the title above suggests, it is difficult to address health issues without considering the role of the media and everyday life; the time and space when health is produced and cared for or put at risk and exposed. In the introduction to this special issue, ‘Media and health in everyday life’, we will discuss the three components of the theme. We will offer some definitions, but also problem
Interleukin-4 reduces insulin secretion in human islets from healthy but not type-2 diabetic donors
Type 2 diabetes (T2D) is associated with low-grade inflammation. Here we investigate if the anti-inflammatorycytokine interleukin-4 (IL-4) affects glucose-stimulated insulin secretion (GSIS) in human islets from nondiabetic(ND) and type-2 diabetic (T2D) donors. We first confirmed that GSIS is reduced in islets from T2Ddonors. Treatment with IL-4 for 48 h had no further effect on GSIS in these isle

ManyBirds : A multi-site collaborative Open Science approach to avian cognition and behavior research
Comparative cognitive and behavior research aims to investigate cognitive evolution by comparing performance in different species to understand how these abilities have evolved. Ideally, this requires large and diversesamples; however, these can be difficult to obtain by single labs or institutions, leading to potential reproducibility and generalization issues with small, less representative samp
Naive poison frog tadpoles use bi-modal cues to avoid insect predators but not heterospecific predatory tadpoles
For animals to survive until reproduction, it is crucial that juveniles successfully detect potential predators and respond with appropriate behavior. The recognition of cues originating from predators can be innate or learned. Cues of various modalities might be used alone or in multi-modal combinations to detect and distinguish predators but studies investigating multi-modal integration in p
From Fleece to Thread : Interdisciplinary Evidence for the Origins of Sheep Wool
Sheep wool was used in the production of textiles across Europe from prehistoric times onwards, but its origins remain unclear. Textiles are rarely preserved in the archaeological record, but further indirect evidence supports their use, such as the study of textile tools, osteology, and terminology. Moreover, new analytical methods, such as protein and DNA analysis, enable the identification of w
