The perceptual effects of manipulating nonlinear phenomena in synthetic nonverbal vocalizations

The communicative role of nonlinear vocal phenomena remains poorly understood since they are difficult to manipulate or even measure with conventional tools. In this study parametric voice synthesis was employed to add pitch jumps, subharmonics/sidebands, and chaos to synthetic human nonverbal vocalizations. In Experiment 1 (86 participants, 144 sounds), chaos was associated with lower valence, an

Approaching the potential of model-data comparisons of global land carbon storage

Carbon storage dynamics in vegetation and soil are determined by the balance of carbon influx and turnover. Estimates of these opposing fluxes differ markedly among different empirical datasets and models leading to uncertainty and divergent trends. To trace the origin of such discrepancies through time and across major biomes and climatic regions, we used a model-data fusion framework. The framew

Ectosymbionts alter spontaneous responses to the Earth’s magnetic field in a crustacean

Magnetic sensing is used to structure every-day, non-migratory behaviours in many animals. We show that crayfish exhibit robust spontaneous magnetic alignment responses. These magnetic behaviours are altered by interactions with Branchiobdellidan worms, which are obligate ectosymbionts. Branchiobdellidan worms have previously been shown to have positive effects on host growth when present at moder

Asymmetric paralog evolution between the “cryptic” gene Bmp16 and its well-studied sister genes Bmp2 and Bmp4

The vertebrate gene repertoire is characterized by “cryptic” genes whose identification has been hampered by their absence from the genomes of well-studied species. One example is the Bmp16 gene, a paralog of the developmental key genes Bmp2 and -4. We focus on the Bmp2/4/16 group of genes to study the evolutionary dynamics following gen(om)e duplications with special emphasis on the poorly studie

Laser-wakefield accelerators for high-resolution X-ray imaging of complex microstructures

Laser-wakefield accelerators (LWFAs) are high acceleration-gradient plasma-based particle accelerators capable of producing ultra-relativistic electron beams. Within the strong focusing fields of the wakefield, accelerated electrons undergo betatron oscillations, emitting a bright pulse of X-rays with a micrometer-scale source size that may be used for imaging applications. Non-destructive X-ray p

Comparative analysis of detailed and reduced kinetic models for CH 4 + H 2 combustion

Directed relation graph with error propagation (DRGEP) method combined with extensive validation for 0D, 1D and 2D CFD modeling supported by sensitivity and Rate-Of-Production (ROP) analyses are implemented for comparative study of detailed and reduced kinetic mechanisms for CH 4 + H 2 combustion. To this end, two detailed kinetic mechanisms, namely AramcoMech 2.0 and recently updated Konnov me

High resolution of colour vision, but low contrast sensitivity in a diurnal raptor

Animals are thought to use achromatic signals to detect small (or distant) objects and chromatic signals for large (or nearby) objects. While the spatial resolution of the achromatic channel has been widely studied, the spatial resolution of the chromatic channel has rarely been estimated. Using an operant conditioning method, we determined (i) the achromatic contrast sensitivity function and (ii)

Income tax progressivity and war inflation during the two World Wars

Top marginal rates in income taxes increased significantly during the two World Wars in most Western countries, which points towards increases in their progressivity. We argue, however, that this war-related effect is less clear-cut than previously thought: wartime inflation could have exerted a counteracting impact by pushing citizens into higher tax brackets, including new individuals from the b

Source specific exposure and risk assessment for indoor aerosols

Poor air quality is a leading contributor to the global disease burden and total number of deaths worldwide. Humans spend most of their time in built environments where the majority of the inhalation exposure occurs. Indoor Air Quality (IAQ) is challenged by outdoor air pollution entering indoors through ventilation and infiltration and by indoor emission sources. The aim of this study was to unde

Fishing for nutrients – economic effects of fisheries management targeting eutrophication in the Baltic Sea

The Baltic Sea is one of the most eutrophied seas in the world, facing challenges with both hypoxia and algae blooms. In this study we analyse the effect of using different fishery policy instruments to reduce nutrient loads by removing fish biomass from the ecosystem. The study covers Danish, Finnish and Swedish pelagic fisheries. We distinguish between a private optimum maximising the net presen

The relational spatiality of the postwar condition : A study of the city of Mitrovica

The postwar condition – the period where war is over yet the socio-political ordering of any given postwar entity remains contested and an unchallenged peace has still to be reached – is inherently spatial. This spatiality, however, has yet be fully addressed in theoretical and analytical terms, meaning that we neither understand it in its entirety nor have the tools with which to explore it thoro

Owls lack UV-sensitive cone opsin and red oil droplets, but see UV light at night : Retinal transcriptomes and ocular media transmittance

Most diurnal birds have cone-dominated retinae and tetrachromatic colour vision based on ultra-violet/violet-sensitive UV/V cones expressing short wavelength-sensitive opsin 1 (SWS1), S cones expressing short wavelength-sensitive opsin 2 (SWS2), M cones expressing medium wavelength-sensitive opsin (RH2) and L cones expressing long wavelength-sensitive opsin (LWS). Double cones (D) express LWS but

Using micro-CT techniques to explore the role of sex and hair in the functional morphology of bumblebee (Bombus terrestris) ocelli

Many insects have triplets of camera type eyes, called ocelli, whose function remains unclear for most species. Here, we investigate the ocelli of the bumblebee, Bombus terrestris, using reconstructed 3D data from X-ray microtomography scans combined with computational ray-tracing simulations. This method enables us, not only to predict the visual fields of the ocelli, but to explore for the first

The GALAH Survey : Lithium-strong KM dwarfs

Identifying and characterizing young stars in the Solar neighbourhood is essential to find and describe planets in the early stages of their evolution. This work seeks to identify nearby young stars showing a lithium 6708 Å absorption line in the GALAH survey. A robust, data-driven approach is used to search for corresponding templates in the pool of 434 215 measured dwarf spectra in the survey. I

Contextual Awareness on Organizational Crises : National Contexts and Crisis Attribution

This study examines the influences of national contexts on crisis attribution to address the recent appeal for a more contextually sensitive perspective in crisis communication research. Specifically, this study revisits the Situational Crisis Communication Theory (SCCT) in the Chinese context by taking an online discussion on Weibo about a high-profile homicide in a McDonald’s restaurant as the c
