Purpose: Artifacts impacting the imaged tumor volume can be seen in conventional three-dimensional CT (3DCT) scans for planning of lung cancer radiotherapy but can be reduced with the use of respiration-correlated imaging, i.e., 4DCT or breathhold CT (BHCT) scans. The aim of this study was to compare delineated gross tumor volume (GTV) sizes in 3DCT, 4DCT, and BHCT scans of patients with lung tumo

With a view to working toward urban sustainability goals, two Swedish research platforms, SLU Urban Futures at the University of Agricultural Sciences in Alnarp (SLU) and the Urban Arena at Lund University, launched Urban Forum, a transdisciplinary dialogue format, in 2019. Designed to foster exchange between practitioners and scholars in the spatial design fields the Forum convenes actors from pr

There has not been a satisfying numerical validation of the theory of effective waves in random particulate materials. Validation has been challenging because the theoretical methods for effective waves have been limited to random particulate media in infinite slabs or half-spaces, which require a very large number of particles to perform accurate numerical simulations. This paper offers a solutio

En studie baserad på unik statistik som visar hur företag i det svenska näringslivet använder mjukvarubaserade och datadrivna tjänster samt hur det påverkar näringslivets struktur.

This paper presents delay spread, coherence bandwidth, and angle-of-arrival statistics derived from an extensive MIMO channel measurement campaign carried out at a central frequency of 2.6GHz. The measurement scenarios include indoor-indoor, indoor-outdoor and indoor-outdoor-indoor. The results are useful for analytical and performance studies of post-3G wireless communication systems such as femt

In this paper we propose a shared regression network to jointly estimate the pose of multiple objects, replacing multiple object-specific solutions. We demonstrate that this shared network can outperform other similar approaches that rely on multiple object-specific models by evaluating it on the TLESS dataset using the VSD (Visible Surface Discrepancy). Our approach offers a less complex solution

Current levels and patterns of consumption in affluent societies are highly unsustainable. Research shows that efficiency measures prove insufficient to keep within the planetary boundaries, as they operate within the same consumption paradigm. In response, the sufficiency approach has been put forward, which strives to reduce consumption levels in absolute terms. A growing awareness of the impact

The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. The model was used to analyse an existing system in Denmark with 15 connected single-family detached houses. Each of the houses has a

As the world experiences increasing freshwater crises, researchers turn to saline waters. Can the use of saltwater be expanded? The development of appropriate practices for the use of saline waters for irrigation requires an adequate understanding of how salts affect waters, soils and plants, as FAO states in their book The use of saline waters for crop production, 1992. Plants can grow in saline

The profound changes in perception and cognition induced by psychedelic drugs are thought to act on several levels, including increased glutamatergic activity, altered functional connectivity and an aberrant increase in high-frequency oscillations. To bridge these different levels of observation, we have here performed large-scale multi-structure recordings in freely behaving rats treated with 5-H

We are facing a continuous increase in humanitarian crises. All humanitarian emergencies affect People in Need differently. The wish for a more inclusive picture of the affected people suitable for humanitarian response is becoming more significant. The concept of intersectionality, in the sense of Crenshaw, promises to add precisely this perspective to humanitarian response. With the help of meth

This thesis analyses how conspiracy narratives are used to negotiate a collective identity within the global branch of the Freedom Convoy movement. To better understand what common conspiracies are present and how they function for the group’s collective identity, this paper is based on empirical data from text messages and memes shared in a group chat on Telegram, an instant messaging platform. W

Introduction There has been a drastic increase in the reported number of people seeking help for gender dysphoria in many countries over the last two decades. Yet, our knowledge of gender dysphoria and related outcomes is restricted due to the lack of high-quality studies employing comprehensive approaches. This longitudinal study aims to enhance our knowledge of gender dysphoria; different aspect

Background: Choice theory stems from psychological concepts like self-concept, successful identity, and quality of the world. The theory encourages adolescents to accept the responsibility for their choices on the one hand and predict the effect of such decisions on their lives on the other hand. The present study aimed to investigate the effectiveness of choice theory-based group training in inte

The vast majority of students at universities in Sweden are members of student unions. Universities strongly encourage students to enter unions as they give access to discounts, social events, clubs, and internships. Student unions are tasked with representing students towards the university. In addition, union membership in Sweden is rarely believed to have a political connotation. While often be
