Extremal Polynomials and Sets of Minimal Capacity

This article examines the asymptotic behavior of the Widom factors, denoted Wn, for Chebyshev polynomials of finite unions of Jordan arcs. We prove that, in contrast to Widom’s proposal in Widom (Adv Math 3:127–232, 1969), when dealing with a single smooth Jordan arc, Wn converges to 2 exclusively when the arc is a straight line segment. Our main focus is on analysing polynomial preimages of the i

Modeling Ecosystem Regulation Services and Performing Cost–Benefit Analysis for Climate Change Mitigation through Nature-Based Solutions Using InVEST Models

Climate change and land degradation menace ecosystem sustainability. This study assessed the effectiveness of integrating nature-based solutions (NBSs); soil and water conservation techniques, agroforestry, and reforestation, to mitigate these impacts. Focusing on carbon storage and sediment retention at the watershed level (Sidi Barrak), the InVEST model quantified changes from 1990 to 2050 under

What is in the learner’s mind when trying to verbalize grammatical rules? : English third-person singular -s in two settings, Sweden and Vietnam.

The present study examines the outcome of teaching second language English (L2 English) third-person singular present tense -s for declarative knowledge in two different settings, namely Sweden and Vietnam. Third person -s is one of the most studied grammatical structures in second language acquisition research. Data are collected in two classroom contexts with different teaching traditions. Parti

Språktypologi och språkinlärning

Språklig mångfald är inget nytt, och inte heller något ovanligt, varken i Sverige eller i övriga världen. Cirka 200 olika språk talas i dagens Sverige och nästan alla världens språkfamiljer är representerade. Hur ser de ut? Hur används de? Hur lär man sig dem?De germanska språken är nära besläktade och har många gemensamma drag som vi kan känna igen. Andra språk kan se helt annorlunda ut. Genom at

Trends in population-based incidence, diagnostics, and mortality of acute superior mesenteric artery occlusion

Acute occlusion of the superior mesenteric artery (SMA) results in lethal intestinal ischemia. Results from two previous population-based studies in Malmö, Sweden, suggest a decreasing incidence of acute SMA occlusion. This study aimed to evaluate trends in the epidemiology of acute SMA occlusion in Malmö. The report was a retrospective population-based study conducted from 2014 to 2019 on patient

AI and the everyday political economy of global health

In the last few years, we have seen an explosion in the scale and scope of AI health, a trend only exacerbated by COVID-19. Due to the uptake of AI applications in health, the global health landscape has seen significant shifts. To help understand this development and how best to achieve the potential of AI health technologies, it is necessary to critically look at the global political economy thr

Moving away from, moving towards and moving against others : An adaptive multi-strategy approach to defend and build resources in self-protection mode

In the face of extreme and enduring stressors, a self-protection coping mode can be entered to conserve resources (Conservation of Resources (COR) theory principle 4). Self-protection coping is underexplored in COR theory yet may offer insights about how people deal with the significant challenges posed by work today. We investigate this using a large-group collaborative auto-ethnography (CAE) wit

Conducting research within the acronym : Problematizing LGBTIQ+ research in psychology

LGBTIQ+ research acknowledges shared experiences of groups marginalized due to gender identities, sexualities, and sex characteristics. This universalist coalition approach has resulted in much affirmational research and progressive policy development. However, it risks homogenizing the unique experiences and needs of specific groups; a risk lessened by a particularist subgroup approach. In this t

Global governance and the normalization of artificial intelligence as ‘good’ for human health

The term ‘artificial intelligence’ has arguably come to function in political discourse as, what Laclau called, an ‘empty signifier’. This article traces the shifting political discourse on AI within three key institutions of global governance–OHCHR, WHO, and UNESCO–and, in so doing, highlights the role of ‘crisis’ moments in justifying a series of pivotal re-articulations. Most important has been

The impact of a mobile geriatric acute team on healthcare consumption

PURPOSE: This study describes the effects of a mobile geriatric acute team (GAT) treating acutely ill geriatric patients in their homes. GAT offered more advanced diagnostic and treatment options than are normally available to primary-care led mobile teams. The aim of this study was to evaluate if interventions by GAT had effect on the number of emergency department (ED) visits, hospitalisations,

We address the non-convex optimisation problem of finding a sparse matrix on the Stiefel manifold (matrices with mutually orthogonal columns of unit length) that maximises (or minimises) a quadratic objective function. Optimisation problems on the Stiefel manifold occur for example in spectral relaxations of various combinatorial problems, such as graph matching, clustering, or permutation synchro

Psychometric properties of the arabic version of occupational value with pre-defined ítems

BACKGROUND: Perceived occupational value is closely linked with well-being and there is need worldwide for assessment tools that target this phenomenon. The Occupational Value with pre-defined items (OVal-pd), measuring three dimensions of occupational value; concrete, socio-symbolic and self-rewarding, was designed for that purpose.AIM: To pilot an Arabic version of OVal-pd and evaluate its psych

Fabulating Futures for Flourishing and Vibrant Worlds

This one-day workshop will explore fabulations in design research. Bringing together design researchers and practitioners in hands-on exploration and critical dialogue, we will explore emerging practices and potentials of using fabulations in futures-oriented and exploratory practice-based design research. Drawing on fabulations’ relations with feminist technoscience and more-than-human concerns,

Assessment of the Initial and Modified Parsonnet score in mortality prediction of the patients operated in the Sarajevo Heart center

This study has been conducted in an effort to establish more suitable and accurate scoring model we use in everyday practice. Among the specific outcome prediction models, in 1989 Parsonnet et al elaborated a method of uniform risk stratification for evaluation of the results of cardiac surgery procedures. We have tested two forms of the Parsonnet score, Initial and Modified Parsonnet score, in ou

Performance of PCR-based syndromic testing compared to bacterial culture in patients with suspected pneumonia applying microscopy for quality assessment

Syndromic testing for lower respiratory tract infections with BioFire® FilmArray® Pneumonia Panel Plus (BF) detects 27 pathogens with a turn-around-time of one hour. We compared the performance of BF with culture. Samples from 298 hospitalized patients with suspected pneumonia routinely sent for culture were also analyzed using BF. Retrospectively, patients were clinically categorized as having "p

Change in economic burden of diarrhoea in children under-five in Bangladesh : 2007 vs. 2018

BACKGROUND: In Bangladesh, diarrhoea in children under-five is a major public health problem with cost implications. Although under-five diarrhoea mortality and morbidity have declined from 2007 to 2018, change in the economic burden is unknown. This study determined the change in the societal economic burden of under-five diarrhoea in Bangladesh comparing 2007 to 2018.METHODS: A prevalence-based,

In vivo dendritic cell reprogramming for cancer immunotherapy

Immunotherapy can lead to long-term survival for some cancer patients, yet generalized success has been hampered by insufficient antigen presentation and exclusion of immunogenic cells from the tumor microenvironment. Here, we developed an approach to reprogram tumor cells in vivo by adenoviral delivery of the transcription factors PU.1, IRF8, and BATF3, which enabled them to present antigens as t
