Model-Based Predictive Impedance Variation for Obstacle Avoidance in Safe Human–Robot Collaboration

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

Prolonged SARS-CoV-2 Viremia in an Immunocompromised Patient

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

Iterative Reference Learning for Cartesian Impedance Control of Robot Manipulators

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

Who is a service user?

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 presence, maintenance, and adaptation of Indigenous and local knowledge about climate-related hazards in Nordic contexts

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

Benchmarking an engineering model to estimate hot gas layer interface height

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.

Rotational Locomotion in Large-Scale Environments: A Survey and Implications for Evidence-Based Design Practice

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

Pastureland restoration is urgent for Sámi reindeer pastoralism to coexist with the forest industry and adapt to climate change in Northern Sweden

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

Balance and gait disorders in de novo Parkinson’s disease : support for early rehabilitation

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).

Art, aging, and artificial intelligence: Exploring age scripts in the universe of ai-generated art

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

Hawaiiskjortans estetik

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).

RealTimeTransport: An open-source C++ library for quantum transport simulations in the strong coupling regime

The description of quantum transport in the strong system-reservoir coupling regime poses a significant theoretical and computational challenge that demands specialized tools for accurate analysis. RealTimeTransport is a new open-source C++ library that enables the computation of both stationary and transient transport observables for generic quantum systems connected to metallic reservoirs. It co

A Call to Holiness : Baptism, the Church, and Asceticism in Jerome's Adversus Jovinianum

Scholarship on the Jovinianist controversy has shown that the idea of baptism as deeply transformative lay at the heart of Jovinian's thinking. Scholars have likewise held that Jerome, who through his Adversus Jovinianum is our main source to the ideas of Jovinian, did not acknowledge the ecclesiological concerns on which his opponent's argument was based. This article argues, to the contrary, tha

Proposal for revised criteria for daylight provision in the European daylight standard based on calculations for Swedish multifamily residential buildings

The European standard EN 17037 was first introduced in 2018 with the aim of encouraging building designers to ensure adequate daylight in buildings. Experience has shown that the standard’s criteria for daylight provision are generally perceived to be too challenging, and this in turn has hindered its implementation in national legislations. This article proposes a revised illuminance-based criter

Actin/myosin-based gliding motility in apicomplexan parasites

Apicomplexan parasites move and actively enter host cells by substrate-dependent gliding motility, an unusual form of eukaryotic locomotion that differs fundamentally from the motility of prokaryotic and viral pathogens. Recent research has uncovered some of the cellular and molecular mechanisms underlying parasite motility, transmigration, and cell invasion during life cycle progression. The glid

Emotions of perpetrators and victim-survivors: multi-layered violence against Chinese women during the Asia-Pacific War

This essay uses a microhistory of Chinese comfort women during the Asia-Pacific War to illuminate the gendered dynamics of violence and the contrasting emotions experienced by both sexually abused women and their Japanese perpetrators, forming a perpetrator-victim dyad. The essay employs the concept of intersectional emotions within a micro-historical framework to demonstrate that this violence ag
