The Australian Bogong moth (Agrotis infusa) is a small noctuid moth that undertakes annual, nocturnal migrations of up to 1000 km to escape the summer heat of its breeding grounds. The moths travel to cool alpine caves, where they enter a dormant state (aestivation) before returning to reproduce and die. During migration, their brains integrate magnetic and visual cues to guide their flight direct

We present FACT, a method for predicting alignment quality (i.e., registration error) of registered lidar point cloud pairs. This is useful e.g. for quality assurance of large, automatically registered 3D models. FACT extracts local features from a registered pair and processes them with a point transformer-based network to predict a misalignment class. We generalize prior work that study binary a

Digitalisering av kulturarvssamlingar – vad är det? Den här boken handlar om Vetenskapsrådets Digarvprogram, som pågick mellan 2018 och 2025, och summerar dess skiftande digitaliserings- och forskningsverksamheter. Grundtanken har varit att i fjorton kapitel – ett för varje projekt som ingick i programmet – beskriva vad forskarna ägnat sig åt och resonera om erfarenheter och utmaningar som projekt

Putin kan välja att avsluta kriget i Ukraina – frågan är om han har råd med det. Fred är farligt, i alla fall om man är president i Ryssland. Och respekten för den som tappar makten försvinner snabbt. Att eskalera spänningar är därför en ren självbevarelsedrift. Ukraina är en huvudvärk för Putin, men den är inte hans värsta, skriver historikern Tomas Sniegon vid Lunds universitet.

Vocabularies of space define the world. Yet, despite their apparent conceptual authority (Harley 1989), the lineagesof cartographic entities are often blurred, accidental, and produced from etymologies only imperfectly understoodby their users. Drawing on a recent study on past and present meanings of the term ‘Mesopotamia’ (Rattenborg2018), this paper reviews the inadvertent, if now firmly embedd

Visste du att en elbil är minst 40% mer effektiv än en bil som går på bensin? Det är sant! En bil med förbränningsmotor kan maximalt utnyttja runt 40% av energin som finns i bensinen. En elbil däremot, kan idag använda upp till 97% av energin i batteriet. Med detta i åtanke känns det ganska naturligt att elbilar kommer bli allt vanligare i samhället, till och med om man bortser från miljöaspekten.The global energy transition and the growing adoption of electric vehicles drives an ever-increasing demand for more efficient electrical machines. A key improvement area is understanding and reducing iron losses in machine magnetic materials, such as those caused by Pulse Width Modulation (PWM). This thesis investigates the effects of PWM on magnetic hysteresis and the resulting iron losses in Fe

The cranked Nilsson-Strutinsky formalism is employed to investigate the band structure of 115I from low to high spin. A set of eight rotational bands with well established spins and parities are analyzed. Five bands start at low spin and are assigned to the single-particle proton orbitals (𝑑5/2, 𝑔7/2), 𝑔9/2, and ℎ11/2, which are close to the Z = 53 Fermi surface for a deformation of ɛ2=0.2. The

Major depressive disorder (MDD) has been linked to altered brain networks and might be relieved by music therapy. Yet, the neurophysiological basis, especially the functional network mechanism, of music therapy on depression remains poorly understood. Here, we apply a novel dynamic module detection method based on block term decomposition (BTD) to examine the reorganization of time-varying topolog

Smoking is widely regarded as a risk factor for type 2 diabetes because nicotine contributes to insulin resistance by desensitizing the insulin receptors in muscle, liver, or fat. Little is known, however, about the immediate regulation of islet hormonal output by nicotine, an agonist of ionotropic cholinergic receptors. We investigated this by imaging cytosolic Ca2+ dynamics in mouse and human is

Acquired von Willebrand syndrome (AVWS) is a rare condition characterized by an acquired functional and/or absolute deficiency of the von Willebrand factor (VWF) protein. The absence of widely accepted diagnostic criteria has hampered accurate estimates of incidence and prevalence, which are largely currently unknown. As bleeding symptoms are not included in the most widely used definitions, AVWS
