We present a case study of a conversation between ourselves and an artificial intelligence-based chatbot ChatGPT. We asked the chatbot to respond to a basic physics question that will be familiar to most physics teachers: ‘A teddy bear is thrown into the air. What is its acceleration in the highest point?’ The chatbot’s responses, while linguistically quite advanced, were unreliable in their corre
”Invasiva främmande arter” är ett uttryck som hörs allt oftare, såväl i medier som i diskussioner vid fikabordet. Vad är då en invasiv främmande art och varför väcker dessa arter så starka känslor? Varför är de ett problem? Hur blir man av med dem? Har de några positiva egenskaper? Det är några av de frågor vi tar upp i den här boken som är ett resultat av det tvärvetenskapliga forskningstemat ”Pe
Background: Gambling disorder (GD) is a behavioural addiction in which a person faces negative consequences due to uncontrolled gambling, such as financial, personal, or relational difficulties. GD more often affects men but both men and women face severe consequences of GD. Psychiatric comorbidity is the rule rather than the exception and suicidality is abundant. Health issues such as obesity and
Aggrecan (ACAN) is localized in the intervertebral disc (IVD) in unique compartment-specific patterns where it contributes to the tissue structure and mechanical function together with collagens. The extracellular matrix (ECM) of the IVD undergoes degenerative changes during aging, misuse or trauma, which inevitably alter the biochemical and biomechanical properties of the tissue. A deeper underst
BACKGROUND: Whether sex-specific differences exist for risk factors for pulmonary embolism (PE) and deep venous thrombosis (DVT), with the exception of pregnancy and estrogen therapy, has been sparsely studied. We aimed to study whether sex-specific differences of risk factors exist for noncancer-related DVT and PE in middle-aged and older individuals without cardiovascular history or previous dia
Introduction: Venous thromboembolism (VTE) is a complex disease that aggregates in families. Both acquired and genetic risk factors are important. Proper recognition and management of high-risk individuals are important. Areas covered: The genetic risk factors for VTE, the clinical consequences, and future perspectives are summarized. Classical thrombophilia i.e., factor V Leiden (rs6025), the pro
When we speak, we typically also gesture. Gestures are an integral part of language use in both production and comprehension. They are therefore also vital in second language (L2), foreign language (FL), and bilingualism studies since they can open new windows on cognitive processes, interaction practices, and learning. This entry discusses methods and tools for studying second language users' and
Avhandlingen är en studie av hur stöd och service organiseras kring fyra barn med funktionshinder och deras familjer. I denna service är normalt flera olika formella organisationer involverade, som barnhabilitering, förskola/skola/särskola, hjälpmedelscentral, assistentorganisationer, sjukvård m fl. Dessutom kan barnets och familjens situation vara komplicerad på många sätt. Själva funktionshindreThis study explores the organising of services for disabled children and their families in Sweden. It is based on 83 interviews with parents and involved staff surrounding four disabled children, with both physical and intellectual disabilities, and between two and nine years old. Further, 15 meetings between parents and staff were observed, primarily serving as background material. The service pr
Lake Urmia, located in northwestern Iran, is the largest salt lake in the Middle East (ME) and one of the largest hypersaline lakes in the world. The lake has an important role in biodiversity preservation and the economic and cultural aspects of its surrounding region. Over the last two decades, the combined effects of climate change and anthropogenic activities have caused a significant depletio
Massive MIMO is one of the leading technologies for connecting very large numbers of energy-constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes into groups that can communicate simultaneously such that the mutual interference is minimized. Here we propose node partitioning strategies that do not require full c
Suspensions of microswimmers are a class of systems inherently out of equilibrium, due to the mechanical work continuously performed by a large number of active agents. Biological examples are plentiful, as many aquatic microorganisms have the ability to propel themselves. A distinct phenomenon displayed by such systems is the increased diffusivity of passive tracer particles, relative to their eq
The Valgarður database is a compilation of data describing the physical and geochemical properties of Icelandic rocks. The dataset comprises 1166 samples obtained from fossil and active geothermal systems as well as from relatively fresh volcanic rocks erupted in subaerial or subaqueous environments. The database includes petrophysical properties (connected and total porosity, grain density, perme
This chapter discusses minuscule gold foil figures from the Scandinavian Late Iron Age anddemonstrates how the figures are continuously in the making, rather than being still representations of gods. In the past, the figures’ affectual qualities, such as their small size, their shininess and their human-like and foldable character, invited play and experimentation, stressing the figures’ ongoingne
Stigande halter av växthusgaser i atmosfären har rubbat balansen i jordens klimatsystem vilket har medfört en snabbt stigande global medeltemperatur. Den globala uppvärmningen ligger nu på drygt 1,1 grader jämfört med förindustriell tid. Utöver högre temperaturer har detta lett till fler extrema väderhändelser, smältande isar och stigande havsnivåer. De ekologiska, ekonomiska och sociala effektern
In this paper we report the linear and non-linear optical properties of metallic nano-clusters in α-Al 2O 3 fabricated by ion implantation (from 2 to 8×10 16 ions/cm 2). Thereafter, the samples were annealed at temperatures from 600 to 1100°C in oxidising, reducing atmospheres. Once spherical nano-particles were synthesized, the samples were further irradiated with Si +++ with different energies a
Metallic nano-particles embedded in transparent dielectrics are very important for new technological applications because of their unique optical properties. These properties depend strongly on the size and shape of the nano-particles. In order to achieve the synthesis of metallic nano-particles it has been used the technique of ion implantation. This is a very common technique because it allows
Nonlinear optical response of Au metallic nanoparticles, synthesized and embedded in sapphire by using ion implantation, as a function of their size and shape is studied. The size of the Au NPs was varied by controlling the annealing time of the gold-irradiated sapphire in a reducing atmosphere. Their shape was changed from approximately spherical to prolate by swift heavy-ion irradiation using Si
