A study of submicron-sized InGaN containing a single quantum well, intended for use as nano-light-emitting diodes in high-resolution display based on direct emission, is presented. Herein, the structures are grown by a bottom-up method from holes in a masked GaN/sapphire substrate and are intended for red emission. Many of the platelets show dark lines in cathodoluminescence images, previously ide

Welfare technology (WT), defined as digital technology enabling individuals to live securely, actively and independently at home, is often viewed as a solution to care resource shortages. This solution discourse has increasingly been problematised, and ethical issues specifically connected to WT have emerged, e.g., regarding quality of care. The existing array of WT is developed with limited user

School-based bullying is a widespread issue, but it occurs less often when bystanders defend the victims. This study examined whether type of bullying and students’ trust in their teacher’s ability to manage the class would be associated with reaction of the bystander (i.e. defending, passive, and pro-bullying). The participants were 202 ninth-grade students in Sweden, aged 15 years, who completed

Human–robot collaboration (HRC) in manufacturing environments requires that physical safety can be guaranteed. Control methods that implicitly regulate the interaction forces between a controlled robot and its environment, such as impedance control, are often used for safety in HRC. However, these methods could be complemented by restricting the robot operational space for additional safety guaran

Immunocompromised patients, especially those receiving B-cell depleting therapies, are at risk for developing atypical presentation with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, with the potential for diagnostic delay and adverse outcomes if such delay occurs. A 66-year-old female with history of granulomatosis with polyangiitis (GPA) with previous pulmonar

In this paper, an iterative learning strategy was developed to improve trajectory tracking for an impedance-controlled robot manipulator. In this learning strategy, an update law was proposed to modify the Cartesian reference of an impedance controller. Also, the conditions that ensure its convergence considering the dynamics of the robot were derived. Finally, an experimental evaluation was perfo

The concept of service user and other related concepts such as service user participation, service user influence and service user perspective have in recent decades gained increased importance in discussions about the development of social work practice, research and education. However, when these concepts are used, there is sometimes a lack of a well-thought-trough reflection on what is meant. W

The ability of people to act on their knowledge of their surrounding physical environments before, in response to, and after impactful climate-related hazards is shaped by broader environmental and socio-economic conditions. We present a multiple case study that illustrates how people from both non-Indigenous and Indigenous communities living in remote areas in the Nordic countries maintain and ad

An engineering model for estimating hot gas layer height is presented. The model is based on several sub-models, thus necessitating benchmarking against experimental data. Results from the model are compared to data from three different series of enclosure fire tests. The results indicate a strong correlation between the proposed model and the experimental observations, with an average error of leAn engineering model for estimating hot gas layer height is presented.

A medium-scale experimental setup located in Revinge, Sweden, is used to generate new repeated experimental datasets focussed on measuring a set of key variables, including time-temperature curves and temperature profiles. A total of 6 repeated fire tests were conducted and are here used to exemplify typical issues associated with repeatability, uncertainty and variability in tunnel fire experimen

Navigation performance in urban and large-scale built-up spaces (e.g. airports, train-stations, hospitals) depends on gradual environmental perception during locomotion, and spatial knowledge acquisition, update/integration at different times along a path. Rotational locomotion is regularly involved in everyday navigation; this, combined with the fact that people cannot perceive the whole of a lar

Key recommendationsPastureland restoration must be implemented to reduce dependency oncoping mechanisms such as emergency feeding, mechanized transport andintense workloads. These coping mechanisms are increasingly used to dealwith the cumulative effects of encroachments from competing land uses,predator pressure, and the impacts of climate change on snow conditions.Vigorous thinning of dense, man

BACKGROUND: Postural instability is considered a late complication of Parkinson’sdisease (PD). However, growing evidence shows that balance and gait problems mayoccur early in the disease.OBJECTIVE: To describe balance, gait, and falls/near falls in persons with newlydiagnosed, untreated PD (“de novo”), and to compare this with persons with mildmoderatePD (Later PD). In addition, we evaluated diffBackgroundPostural instability is considered a late complication of Parkinson’s disease (PD).

Local genetic correlation analysis is an important tool for identifying genetic loci with shared biology across traits. Recently, Border et al. have shown that the results of these analyses are confounded by cross-trait assortative mating (xAM), leading to many false-positive findings. Here, we describe LAVA-Knock, a local genetic correlation method that builds off an existing genetic correlation

This study investigates age-related biases in AI-generated art through a mixed method investigation of images of older and younger individuals. Employing 19 text prompts associated with social exclusion for older adults, we collected 465 images from an AI-art generator, MidJourney, and conducted quantitative and qualitative analyses to understand differences between age group depictions. We used A

En kulturhistorisk perspketivering med plagget Hawaiiskjortan i fokus. Dels beskrivs Hawaiiskjortan som sådan, historisk etablering, i ett internetaionellt såväl som inrikes svenskt läge; dels förs resonemang om Hawaiiskjortans symboliska och betydelseproducerande roll i populärkulturen (TV-serier, filmer, musik av olika slag).
