Capturing ultrafast phenomena requires imaging techniques capable of resolving events occurring on femtosecond time scales. Traditional high-speed cameras are limited by electronic readout speeds and cannot reach the terahertz (THz) frame rates necessary to observe processes such as laser filamentation, plasma formation, or light-matter interactions in general. To overcome these limitations, this

Purpose: Mental illness due to longstanding stress is increasing. It has been shown that service users with mental illness may benefit from nature-based interventions (NBI), including equine-assisted therapy, to support their health, recovery, and activity level of daily life. However, the evidence base to support this is still weak. The aim was thus to evaluate and provide knowledge of the possib

In 2015 the Rockefeller Foundation-Lancet Commission defined planetary health as built on an ecological model that integrates the material, biological, social, and cultural aspects of public health and accepts the complexity and non-linearity of the dynamics of natural systems. The zoonotic COVID-19 pandemic hastened this awaking to the symbiotic nature of planetary health politics (PHP), with the

According to Disney, “In Tomorrowland, the future is today!” In 2015 Brad Bird’s eco-science fiction film, Tomorrowland: A World Beyond, was released to coincide with the 60th anniversary of the opening of the futuristic theme park land. The film was described as a “a gorgeous, flawed utopia” but flopped at the box office. The Disneyfication of climate crisis for commercial purpose serves as a veh

For some time now, IR has been experiencing a narrative turn, with an increasing number of empirical analyses using the concept. However, its ontological, epistemological and methodological assumptions and implications are not always addressed. The panel aims to facilitate a conceptual debate on three sets of questions: Ontology: How does our understanding of the concept depend on the social theor

ObjectiveThe 30-second Chair Stand Test (30s CST), a valid and reliable test evaluating lower extremity physical function, has been integrated into a digital eHealth program. We aimed to evaluate the agreement (inter-rater reliability) between digital self-assessment and in-person physiotherapist assessment as well as intra-rater test-retest reliability of digital self-assessment among persons wit

We live in a time where capitalism has long since eliminated any notion of alternative systems from our imaginaries, so that it “occupies the horizon of the thinkable” (Fisher 2009). At the same time, we have seen a (re)turn to positivism and acceptance of the neoliberal system in academia, even in the humanities and studies of art (Grønstad 2020, Poenar 2018). The rejection of the political proje

Human pose forecasting is the task of predicting articulated human motion given past human motion. There exists a number of popular benchmarks that evaluate an array of different models performing human pose forecasting. These benchmarks do not reflect that a human interacting system, such as a delivery robot, observes and plans for the motion of the same individual over an extended period of time

Interpolations in the latent space of deep generative models is one of the standard tools to synthesize semantically meaningful mixtures of generated samples. As the generator function is non-linear, commonly used linear interpolations in the latent space do not yield the shortest paths in the sample space, resulting in non-smooth interpolations. Recent work has therefore equipped the latent space

This masters thesis deals with mathematical signal detection in the field of NQR,Nuclear Quadrapole Resonance, which is a non-invasive spectroscopic technique usedto identify specific substances. The thesis has two main focuses, where the first isto propose novel methods for parameter estimation, especially for identification ofunknown signals. These extend the existing Capon and APES methods for

This study is an explorative examination of changes in employment, revenue, and firm structure for low, mid, and high-skill firms in urban and rural areas in Sweden from 2007 to 2019, using skill groups based on education levels. For employment in Sweden in general, we find evidence of job upgrading. In the city of Stockholm we also document job polarization in the sense that employment in both lo

In this paper we provide a far-reaching generalization of the existent results about invariant subspaces of the differentiation operator D=∂t on C^{\infty}(0,1) and the Volterra operator Vf(t)=∫f(s)ds, on L^{2}(0,1). We use an abstract approach to study invariant subspaces of pairs D,V with DV=I, where V is compact and quasi-nilpotent and D is unbounded densely defined and closed on the same Hilbe

The breakthroughs in generative artificial intelligence (AI) technologies have enabled the creation of hyper-realistic media content that credibly mimics human beings. As AI-generated media (AGM) become more accessible on social media platforms, concerns about young people’s capabilities to deal with mis- and disinformation are rising. This study aims to investigate young people’s practices to ass

The ever-growing reliance on electronic devices and the burgeoning field of green energy necessitate efficient and different gain AC-DC converters for a myriad of applications, from electric drives to solar cells and grid-connected inverters. This paper introduces a hybrid closed-loop bridged and bridgeless Single-Ended Primary-Inductor Converter (SEPIC) topologies featuring switched-capacitor net

Om alla människor hade möjlighet att välja medborgarskap, som man väljer bostad eller annan konsumtion, skulle vi implicit observera deras preferensergenom dessa beslut. Medborgarskap kan betraktas som privat men ej överlåtbar egendom. Om medborgarskapet blev överlåtbart och vi kunde handla meddem och hade en etablerad handelsplats – likt en aktiebörs – skulle vi kunna observera marknadspriser på

The COVID-19 pandemic disrupted the ‘normality’ of our everyday lives, but it did so in the wake of a series of crises within the capitalist system, which worsened the conditions for a liveable world for many while benefitting only a few. In response to these crises, the contributions in this issue highlight the diverse ways activists continue to organise in the midst of social, political, and eco

Microelectronic systems, wind energy applications, battery chargers, DC motor controllers, and home electric appliances all require AC/DC converters for power supply. With a high voltage conversion ratio and minimal EMI emissions, switching capacitor (SC) based converters could be a promising answer to the difficulties of the present century. A bridge SEPIC PFC converter with a mono-switching capa
