Imagination

Imagination is a human capacity that reproduces and transforms experiences and thoughts. The capacity is manifested in children's pretend play and is an important part of adults' ability to process the past, and to plan the future. A first step in the development of imagination is the ability to represent objects and events and to change these representations into alternatives to reality. For adap

EFFECT OF THE GAS DIFFUSION LAYER DEFORMATION ON THE TRANSPORT PROCESSES AND PERFORMANCE OF A PEM FUEL CELL WITH INTERDIGITATED FLOW CHANNELS

When the assembly force is applied, the gas diffusion layer (GDL) deformation is observed and the geometry and transport parameters are also changed. Accordingly, the transport processes and cell performance are affected due to the deformation effect. In the present study, a three-dimensional, non-isothermal, two-phase flow model was developed and applied to investigate the effect of GDL deformati

REDOX POLYMERS FACILITATE ELECTROCHEMICAL COMMUNICATION BETWEEN BACTERIAL CELLS AND ELECTRODES

One way to facilitate electrochemical communication between bacterial cells and electrodes is the use of artificial redox mediators. There are, however, a number of drawbacks when they are used in their freely diffusing monomeric form. In contrast when bound to flexible polymeric backbones they not only serve as mediators but also as an immobilization matrix forming a 3D hydrogel on the electrode

Turning the tide on marine biodiversity loss: How Swedish coastal cities are leveraging citizen interaction to improve conservation outcomes

Rapid coastal urbanization and declining marine biodiversity rates are complex problems that require broad, integrated sets of solutions. Although isolating nature from human impact prevails as the standard conservation approach, social-ecological systems require more holistic solutions. Coastal cities have the opportunity to encourage human interaction with nature – while still achieving positive

A Review of Isobutanol as a Fuel for Internal Combustion Engines

Isobutanol, one of the four isomers of butanol (C4H9OH), possesses some favorable properties that make it an attractive fuel for internal combustion engines. For instance, when compared to ethanol, isobutanol features a higher heating value and lower hygroscopicity (which prevents corrosion and enables it to be transported via pipelines). Moreover, its addition to gasoline does not distort the fue

Data-driven estimation of scalar quantities from planar velocity measurements by deep learning applied to temperature in thermal convection

The measurement of the transport of scalar quantities within flows is oftentimes laborious, difficult or even unfeasible. On the other hand, velocity measurement techniques are very advanced and give high-resolution, high-fidelity experimental data. Hence, we explore the capabilities of a deep learning model to predict the scalar quantity, in our case temperature, from measured velocity data. Our

Pain as bad as you can imagine or extremely severe pain? A randomized controlled trial comparing two pain scale anchors

Background: A common method of pain assessment is the numerical rating scale, where patients are asked to rate their pain on a scale from 0 to 10, where 0 is “no pain” and 10 is “pain as bad as you can imagine”. We hypothesize such language is suboptimal as it involves a test of a cognitive skill, imagination, in the assessment of symptom severity. Methods: We used a large-scale online research re

Effects of low-level RF fields reveal complex pattern of magnetic input to the avian magnetic compass

The avian magnetic compass can be disrupted by weak narrow-band and broadband radio-frequency (RF) fields in the lower MHz range. However, it is unclear whether disruption of the magnetic compass results from the elimination of the perception pattern produced by the magnetic field or from qualitative changes that make the pattern unrecognizable. We show that zebra finches trained in a 4-arm maze t

Bettan – Industrial robot and application for Finja Exakt build system

This paper reports on efforts to create a robotized construction build system, based on the Finja Exakt manual build system. The equipment used is a generic off-the-shelf industrial arm robot integrated with a spindle crane carrier for mobility. The approach offers technical, safety and usability challenges as well as integration and business challenges for placing a generic industrial robot onsit

Experiences of participating in a group-based sensory modulation intervention for mental health service users

BACKGROUND: People with mental health issues often experience difficulties with sensory modulation affecting occupational engagement. Research conducted in inpatient units has shown positive effects of individual sensory modulation interventions, however, research on experiences of group-based interventions in outpatient units is limited. Hence, a group-based sensory modulation intervention was ad

Experimental observation of longer trajectories than previously observed in high-order harmonic generation

We experimentally observe longer than long trajectory influence in high-order harmonic generation (HHG) by varying the peak intensity of the driving laser field either through direct attenuation or by chirping the laser pulse. Using a theoretical Gaussian beam model to simulate spatial interference resulting from quantum path interference, we show that the measured interference patterns cannot be

Searches for lepton-flavour-violating decays of the Higgs boson into eτ and μτ in √s = 13 TeV pp collisions with the ATLAS detector

This paper presents direct searches for lepton flavour violation in Higgs boson decays, H → eτ and H → μτ, performed using data collected with the ATLAS detector at the LHC. The searches are based on a data sample of proton-proton collisions at a centre-of-mass energy s = 13 TeV, corresponding to an integrated luminosity of 138 fb −1. Leptonic (τ → ℓνℓ ντ) and hadronic (τ → hadrons ντ) decays of t

Iodine avidity in papillary and poorly differentiated thyroid cancer is predicted by immunohistochemical and molecular work-up

Background: Successful radioiodine treatment of differentiated thyroid cancer requires iodine avidity: that is, the concentration and retention of iodine in cancer tissue. Several parameters have previously been linked with lower iodine avidity. However, a comprehensive analysis of which factors best predict iodine avidity status, and the magnitude of their impact, is lacking. Methods: Quantitativ

The stable climate of KELT-9b

Even among the most irradiated gas giants, so-called ultra-hot Jupiters, KELT-9b stands out as the hottest planet thus far discovered with a dayside temperature of over 4500 K. At these extreme irradiation levels, we expect an increase in heat redistribution efficiency and a low Bond albedo owed to an extended atmosphere with molecular hydrogen dissociation occurring on the planetary dayside. We p
