Hjärntumörer är en av de vanligaste barncancerdiagnoserna och många som överlever drabbas av sömnstörningar efteråt. Tumörens läge i hjärnan, tillsammans med vilken behandling man får, påverkar hur stor risken är. Det finns dock även andra faktorer som påverkar, och övervikt hos barnet är den enskilt största riskfaktorn för sömnsvårigheter.

One of the classical multi-view geometry problems is the so called P3P problem, where the absolute pose of a calibrated camera is determined from three 2D-to-3D correspondences. Since these solvers form a critical component of many vision systems (e.g. in localization and Structure-from-Motion), there have been significant effort in developing faster and more stable algorithms. While the current s

Al x Ga 1 − x N/GaN high-electron-mobility transistor (HEMT) structures are key components in electronic devices operating at gigahertz or higher frequencies. In order to optimize such HEMT structures, understanding their electronic response at high frequencies and room temperature is required. Here, we present a study of the room temperature free charge carrier properties of the two-dimensional e

BACKGROUND: Several molecular classification systems for bladder cancer have been proposed, but due to differences on how to define molecular subtypes, controversies and misunderstandings have arisen. OBJECTIVE: To discuss different aspects of the molecular classification of bladder cancer and to point to the consequences of using different conceptual approaches. To question some underlying assump

The insect central complex appears to encode and process spatial information through vector manipulation. Here, we draw on recent insights into circuit structure to fuse previous models of sensory-guided navigation, path integration and vector memory. Specifically, we propose that the allocentric encoding of location provided by path integration creates a spatially stable anchor for converging sen

Human brain size changes dynamically through early development, peaks in adolescence, and varies up to 2-fold among adults. However, the molecular genetic underpinnings of interindividual variation in brain size remain unknown. Here, we leveraged postmortem brain RNA sequencing and measurements of brain weight (BW) in 2,531 individuals across three independent datasets to identify 928 genome-wide

Background: In animal models, early initiation of therapeutic cooling, intra-arrest, or restored circulation has been shown to be neuroprotective shortly after cardiac arrest. We aimed to assess the feasibility and cooling efficacy of transnasal evaporative cooling, initiated as early as possible after hospital arrival in patients randomized to cooling in the TTM2 trial. Methods: This study took t

Archaeological investigations have revealed cultural layers with remnants of houses and streets below up to four metres of sand at the southern end of the Falsterbo peninsula in southernmost Sweden. The cultural layers have been dated to the 15th – 16th centuries, based on finds of, for example, coins and ceramics, and interpreted to represent the medieval town Falsterbo. It has been assumed that

The photophysics of layered halide perovskites reveals a rich disposition of exciton behavior. Two-dimensional electronic spectroscopy (2DES) is a powerful technique for investigating such excitonic interactions and dynamics. However, the wide spectral range of layered perovskites presents a challenge in studies utilizing conventional 2DES setups to simultaneously probe their interacting excitonic

We review all symmetry-allowed spin-singlet and spin-triplet superconducting order parameters in graphene (s-wave, d-wave, p-wave, and f-wave) generated by generic on-site, nearest-neighbor, and next-nearest-neighbor pairing interactions in a tight-binding model. For each pairing channel, we calculate both the band structure and the dependence of the density of states on energy, chemical potential

There is limited understanding of how education initiatives geared toward faculty and support staff can foster a capacity for long-term and integrated societal engagement and collaboration within higher education institutions. Using the experiences from a cross-disciplinary pilot course in Sweden, the current study aims to identify features that explicate how skills and academic rigor for engagingThere is limited understanding of how education initiatives geared toward faculty and support staff can foster a capacity for long-term and integrated societal engagement and collaboration within higher education institutions.

In nanoscale systems coupled to finite-size reservoirs, the reservoir temperature may fluctuate due to heat exchange between the system and the reservoirs. To date, a stochastic thermodynamic analysis of heat, work, and entropy production in such systems is, however, missing. Here we fill this gap by analyzing a single-level quantum dot tunnel coupled to a finite-size electronic reservoir. The sys

Perioperative hyponatremia, due to non-osmotic release of the antidiuretic hormone arginine vasopressin, is a serious electrolyte disorder observed in connection with many types of surgery. Since blood loss during surgery contributes to the pathogenesis of hyponatremia, we explored the effect of bleeding on plasma sodium using a controlled hypotensive hemorrhage pig model. After 30-min baseline pe

Serial and time-resolved macromolecular crystallography are on the rise. However, beam time at X-ray free-electron lasers is limited and most thirdgeneration synchrotron-based macromolecular crystallography beamlines do not offer the necessary infrastructure yet. Here, a new setup is demonstrated, based on the JUNGFRAU detector and Jungfraujoch data-acquisition system, that enables collection of k

This chapter explores elite boundary crossing between civil society and other societal sectors—including the state, party politics, and business—and how this may lead to inter-elite integration. We illustrate how qualitative life-work history interviews provide an important complement to established quantitative approaches to the study of elite integration. Through these interviews, we explore theThis chapter explores elite boundary crossing between civil society and other societal sectors—including the state, party politics, and business—and how this may lead to inter-elite integration.

Current food systems pose one of the greatest health and environmental challenges of the 21st century. Expanded utilization of seaweed for food in Western societies seems like one promising measure in the transition toward sustainable food systems. However, introducing and expanding seaweed to new markets brings certain challenges, such as limited food acceptance and availability.

Stora företag i västvärlden har de senaste åren i ökad takt inkorporerat social rättvisa (jämställdhet, HBTQ+ rättigheter, rättvisa i rasfrågan) och miljörättvisa i deras marknadsföring och reklam. Modebranschen är en av de branscher som har använt sig särskilt mycket av social rättvise-symbolik. Denna avhandling fokuserar på artikulationer av miljö, genus, och ras genom en studie av hållbarhet ocThe corporatisation of social justice (gender justice, LGBTQI+ rights, racial justice) and environmental justice ideals in the last decades has grown immensely in western countries, exemplified by rainbow-clad ATM’s during Pride month or Nike using images of NFL player Kaepernick’s anti-racism protest action of taking a knee during the USA national anthem in a marketing campaign. One of the indust

Salts affect the solvation thermodynamics of molecules of all sizes; the Hofmeister series is a prime example in which different ions lead to salting-in or salting-out of aqueous proteins. Early work of Tanford led to the discovery that the solvation of molecular surface motifs is proportional to the solvent accessible surface area (SASA), and later studies have shown that the proportionality cons

Many species of insects undertake long-range, seasonally reversed migrations, displaying sophisticated orientation behaviors to optimize their migratory trajectories. However, when invasive insects arrive in new biogeographical regions, it is unclear if migrants retain (or how quickly they regain) ancestral migratory traits, such as seasonally preferred flight headings. Here we present behavioral
