Here we report on findings for four rock samples with melt texture found in a gravel pit within a glaciofluvial deposit near the small town of Kitkiöjärvi in northernmost Sweden. The samples are comprised of granitic clasts embedded in a brown fine-grained melt matrix. The samples all contain quartz grains and/or clasts exhibiting multiple sets of planar deformation features oriented parallel to c
The avoidance of financial gain in the human body is an international ethical standard that underpins efforts to promote equity in donation and transplantation and to avoid the exploitation of vulnerable populations. The avoidance of financial loss due to donation of organs, tissues, and cells is also now recognized as an ethical imperative that fosters equity in donation and transplantation and s
Makerspaces are becoming increasingly popular due to their capacity for hands-on learning, innovation, collaboration, and the democratisation of technology. While numerous studies have explored makerspace users, they have largely focused on contexts within the Global North or China, leaving a significant gap in understanding the demographics and experiences of individuals who frequent these spaces
Purpose: To analyse graft detachment rates after Descemet stripping automated endothelial keratoplasty (DSAEK) using surgeon-cut grafts and pre-cut grafts transported in different mediums. Methods: A retrospective study of graft detachment rates including 265 surgeries (240 patients) performed between 2019 and 2023. The DSAEK grafts were either surgeon-cut (n = 135) or pre-cut and transported in a
This study examines how one may detect Parkinson’s disease (PD) by analyzing voice recordings made with a mobile phone. The key objectives include creating a model that ensures fair and unbiased predictions while maintaining interpretability that is consistent with the existing literature on PD. We introduce a novel group-wise scaling method to address typical age and biological sex biases in the
Altricial songbirds transform themselves from naked poikilotherms to fully feathered endothermic homeotherms over a matter of days from hatching to fledging. The ontogeny of endothermy is a developmental milestone for birds that not only face warmer average temperatures, but also increasingly frequent cold snaps and extreme weather. The timing of development of endothermy has been studied in altri
Ultraviolet rays are known to have positive effect on psoriasis, but the cold climate and latitude in Northern Europe reduce access to the sun. Climatotherapy is a treatment modality where the patient is relocated to a warmer region with a high ultraviolet (UV) index. Young patients with psoriasis can be particularly burdened by the disease, and studies have shown an association between psoriasis
In this work, we consider the problem of localizing multiple signal sources based on time-difference of arrival (TDOA) measurements. In the blind setting, in which the source signals are not known, the localization task is challenging due to the data association problem. That is, it is not known which of the TDOA measurements correspond to the same source. Herein, we propose to perform joint local
The incidence of papillary thyroid cancer (PTC) has been steadily rising, though the underlying mechanism remains unclear. This study aims to elucidate the biological role of TM4SF4 in the PTC progression. Our differential expression analysis indicated that TM4SF4 was significantly upregulated in PTC, which was corroborated in both our local cohort and the data from Human Protein Atlas. Additional
Therapies derived from substances of human origin (SoHOs) such as organs, cells, and tissues provide life-saving or life-changing treatment for millions of people worldwide each year. However, many people lack timely access to SoHO-based therapies because of insufficient supplies of these exceptional health resources and/or broader barriers in access to healthcare. Despite well-established governm
Distributed massive multiple-input multiple-output (D-MIMO) has been identified as a promising technology to meet the service requirements of 6 G wireless networks and beyond. The coordination between a massive number of distributed antennas introduces stiff challenges and requires a substantial amount of computing resources that must be put together with careful algorithm-architecture codesign. T
It is widely believed that Friedrich von Hayek’s first encounter with Gunnar Myrdal involved the latter’s last-minute contribution, as a replacement for Erik Lindahl, to a Sammelband edited by the former in 1933, and that Hayek was lukewarm towards Myrdal and his ideas from the very beginning. Correspondence between the two shows that, in fact Myrdal was among Hayek’s original invitees,and that th
An increasingly globalised world has led to great language diversity in institutional settings. Sweden is no exception; 3 of 10 students in compulsory school have a migrant background. Increased diversity may result in challenges, e.g. knowing how to balance the use of the target language with other languages represented among the students to facilitate learning and interaction. As educational pol
Artificial empathy (AE) is a hotly contested topic. Recently, several empathy researchers have voiced criticism on the prospect of AE, arguing that it is impossible, unethical, or both. Contrary to these sentiments, we believe that further nuance and research are needed to better understand AE, its risks, and what it can potentially contribute to human well-being. We will focus on one obstacle to
Can AI ‘solve’ politics? In this paper, I explore optipolitics, i.e., the idea that politics along with other complex social issues can be framed as mathematical optimization problems and solved as such. I begin by describing politics, optimization, and some reasons for applying the latter to the former. I then present a liberal democratic version of optipolitics and try to defend it against eight
Podcast "Öppet fall" från Lunds universitet, Juridiska fakulteten.Natten mellan den 11 och 12 juli 1908 exploderade en sprängladdning på fartyget Amalthea i Malmö hamn. Det var tre ungsocialister som hade planerat attentatet i protest mot att arbetsgivarsidan i den pågående hamnkonflikten hade kallat in strejkbrytare. Händelsen och dess rättsliga efterspel har mycket att berätta om de framväxande
