Courtship displays are typically conspicuous, elaborate and composed of concomitant signals occurring in different sensory modalities. Although multimodal signals have received increasing attention over the past years, technical issues, in particular the lack of appropriate recording and analytical methods, have long restricted large-scale systematic study of their function. Here, we investigated

Parents face a trade-off when allocating limited resources to reproduction and self-maintenance, and this can result in differential investment in individual offspring when rearing multiple offspring simultaneously. In birds with biparental care, it is not well understood how each parent allocates its resources to different chicks of the same brood. Theory suggests that parental investment depends

Objective: Both auditory and visual hypersensitivity are clinical features of mental fatigue after acquired brain damage or in neurological disorders. Both types of hypersensitivity are also associated with attention deficits, especially in neurodevelopmental syndromes. The aim of this study was to examine auditory and visual hypersensitivity, and associations to attention, in a group of children

BACKGROUND: The advent of direct-to-consumer (DTC) genetic testing (GT) has sparked a number of debates regarding the scientific validity of tests, their broad health and ethical implications for society as well as their legal status. To date, relatively few empirical studies have been published regarding this phenomenon. We conducted a survey of European clinical geneticists to gauge their awaren

The available carbon (C) to phosphorus (P) ratio in soil is regulated by extracellular hydrolases for C and P acquisition by microbes and plants. However, the stoichiometric relationship between acquiring C and P in paddy rhizosphere and bulk soils remains unclear. The objective was to explore the underlying mechanisms of C and P acquisition stoichiometry in rhizosphere and bulk soils in response

This article explores medical assessments of the age of unaccompanied minors seeking asylum in Denmark, to show how, through the medical and bureaucratic aspects of the process, it serves as an imperialist technology of control, as those judged under 18 have greater protection in the asylum system. Since the biggest group of people who are age-estimated in Denmark are Afghans, the author looks at

Reduced ventricular longitudinal shortening measured by atrioventricular plane displacement (AVPD) and global longitudinal strain (GLS) are prognostic markers in heart disease. This study aims to determine if AVPD and GLS with cardiovascular magnetic resonance (CMR) are independent predictors of cardiovascular (CV) and all-cause death also in heart failure with reduced ejection fraction (HFrEF). P

Innovation är en kraft som står bakom förändringen i vår vardag. Till exempel att prata med någon på andra sidan jordklotet med en mobil eller beställa dina matvaror eller skor på din smarta mobil. Det var otänkbart för mindre än 40 år sedan. Vi vill naturligtvis att innovationer i vårt samhälle ska fortsätta förbättra våra liv. Men innovationsverksamhet och att generera nya produkter, tjänster, aInnovation measurement and metrics have fascinated scholars from several disciplines over the last decade. Allthese diverse contributions, however, have resulted in a current state of knowledge that is signified by largenumbers of articles without clear integration and synthesis. Therefore, this thesis aims to increase thetheoretical, empirical, and practical understanding of innovation measuremen

Background: Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. However, race in eGFR equations is a social and not a biologic construct.Methods: We developed new eGFR equations without race using data from two development data sets: 10 studies (8254 participants, 31.5% Black) for serum c

Introduction Mechanical ventilation can be monitored by analysing particles in exhaled air as measured by particle flow rate (PFR). This could be a potential method of detecting ventilator-induced lung injury (VILI) before changes in conventional parameters can be detected. The aim of this study was to investigate PFR during different ventilation modes in patients without lung pathology. Method A

The measurement of innovation is a challenging task for management accounting practitioners and researchers alike. To tackle this task, key performance indicators (KPIs) can be used to measure and follow up innovation. This case study shows how KPIs are used to measure innovation after strategic changes due to competitive pressures. The findings of this study indicate that KPIs in innovation are uMeasuring innovation is a challenging but essential task to improve business performance. To tackle this task, key performance indicators (KPIs) can be used to measure and monitor innovation. The objective of this study is to explore how KPIs, designed for measuring innovation, are used in practice. To achieve this objective, the author draws upon literature on business performance in accounting a

I slutet av juli har en grupp botaniker inventerat kärlväxter i låglandet i Stora Sjöfallets nationalpark. Syftet med inventeringen var att samla in kunskap till Svenska Botaniska Föreningens kärlväxtatlas.

This study aims to explore the variety of previously unknown morphologies that brain lipids form in aqueous solutions. We study how these structures are dependent on cholesterol content, salt solution composition, and temperature. For this purpose, dispersions of porcine sphingomyelin with varying amounts of cholesterol as well as dispersions of porcine brain lipid extracts were investigated. We u

In this paper, we study the effect of optimizing the per-antenna digital predistortion (DPD) sizes on the performance of the downlink massive MIMO system with residual hardware impairment. In particular, we first quantify the capacity after applying some per-antenna DPD with different numbers of coefficients at each antenna and then maximize the capacity by finding optimum values of the per-antenn
