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

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

Climate change, migration, social injustice and loss of biodiversity are all examples of wicked problems that society is facing. The complexity and boundary-spanning nature of wicked problems require not only new competencies and skills, but also a different mindset. The responsibility of higher education is to ensure that the young people we educate are equipped with the knowledge, competencies a

Dateringen för uppförandet av Kämpinge kyrka på Falsterbohalvön var okänd fram till 1987. Det året undersökte lärare och studenter från Lunds universitet byggnaden och kyrkogården. Kyrkan visade sig vara byggd omkring år 1400 och utformad med långhus, kor och tresidigt avslutat kor. Ett sidoaltare vid norra tvärskeppet och ett högaltare dokumenterades, liksom två separata golvnivåer och fundament The construction date for Kämpinge church on the Falsterbo peninsula was unknown until 1987. In that year, teachers and students from Lund University investigated the building and the cemetery. The church was found to be built around 1400 AD and designed with a nave, chancel and three-sided chancel gable. A side altar at the north transept and a high altar were documented, along with two separate

The distinguishing feature of frequency diverse array (FDA) systems as compared to conventional phased-array and multiple-input multiple-output (MIMO) radar systems is the use of a small frequency offset (FO) across the array elements. Much of the development to date has focused on the FDA-MIMO structure, using an FO that is larger than the bandwidth of the baseband signal, thereby reducing the re

Radiation resistant inorganic materials emitting cross-luminescence are one of the most prospective candidates for new generation ultrafast detectors for medical tomography. Radiative transitions leading to cross-luminescence occur between valence and core states, and therefore calculations of the electronic structure of doped materials can explain ultrafast transitions and predict new cross-lumin

Introduction: The radiology department plays an important role in healthcare settings, facilitating diagnoses using different imaging modalities, including ultrasound. However, this high-tech environment can pose various risks to patients. In this study, we aimed to describe the risk of patient safety incidents, and factors associated with the prevention of risks related to ultrasound examinations

High-entropy perovskite catalyst was synthesized and utilized for the first time in the MSR catalytic reaction. Among the HEPs, La(CoCuFeAlCe)0.2O3 exhibited excellent MSR activity and high selectivity. The mechanism of the MSR reaction on the catalyst (100) surface was studied by employing DFT. The results indicate that the surface of La(CoCuFeAlCe)0.2O3 catalyst has the lowest energy barrier, wh
