Knowledge of the forest biomass and its change in time is crucial to understanding the carbon cycle and its interactions with climate change. LiDAR (Light Detection and Ranging) technology, in this respect, has proven to be a valuable tool, providing reliable estimates of aboveground biomass (AGB). The overall goal of this study was to develop a method for assessing AGB using a synergy of low poin
Popular Abstract in Swedish SVENSK SAMMANFATTNING (SUMMARY IN SWEDISH) Hematopoes och leukemi Hematopoes är benämningen på den process vari alla blodceller genom hela livet kontinuerligt utvecklas i benmärgen, samt vid bildandet av lymfocyter även i lymfkörtlarna. Varje dygn bildas det ca 1012 nya celler i benmärgen för att ersätta uttjänta blodceller som dör och bryts ned. Ett litet antal stamcelWilms’ tumour gene 1 (WT1) encodes a zinc-finger transcription factor functioning as a key regulator in organ development. WT1 was first identified as a tumour suppressor gene due to its inactivation in Wilms’ tumour cases, a childhood kidney cancer. In adult tissues WT1 expression is restricted to few organs, but various forms of cancers express high WT1 levels, suggesting an oncogenic potential
Nyhetsmedierna i vårt samhälle är i förändring, och traditionell nyhetsbevakning blir allt svårare att skilja från populärkultur och nöjesmedier. Samtidigt uppvisar framför allt unga människor ett bristande intresse för traditionell medierapportering kring politiska frågor, och vänder sig istället till alternativa källor för information. En sådan källa är The Daily Show, ett satirprogram som fokus
Positioning with 5G signals generally requires connection to several base stations (BSs), which makes positioning more demanding in terms of infrastructure than communications. To address this issue, there have been several theoretical studies on single BS positioning, leveraging high-resolution angle and delay estimation and multipath exploitation possibilities at mmWave frequencies. This paper p
We exhibit supercritical trade-off for monotone circuits, showing that there are functions computable by small circuits for which any small circuit must have depth superlinear or even super-polynomial in the number of variables, far exceeding the linear worst-case upper bound. We obtain similar trade-offs in proof complexity, where we establish the first size-depth trade-offs for cutting planes an
Gaseous ammonia, while influential in atmospheric processes, is critically underrepresented in atmospheric measurements. This limits our understanding of key climate-relevant processes, such as new particle formation, particularly in remote regions. Here, we present highly sensitive, online observations of gaseous ammonia from a coastal site in Antarctica, which allows us to constrain the mechanis
Ice nucleating particles (INPs) play a crucial role in initiating ice crystal formation in clouds, influencing the dynamics and optical properties of clouds and their impacts on precipitation and the climate system. Despite their importance, there is limited knowledge about the vertical distribution of INPs. This study focuses on aircraft measurements conducted during spring 2018 above the boreal
In recent years the concern about the future of the European Union and its supposed lack of democracy, efficiency and legitimacy has increased. This concern has resulted in extensive debates and the establishment of a convention with the task to create a draft treaty for a European Constitution. The aim of this essay is to study how the three theoretical concepts, democracy, efficiency and le
The main purpose of this thesis is to study the Internet governance regime. In order to achieve this, I have a theoretical and an empirical ambition. The first is to develop a process-oriented theoretical framework for studying the evolution of the Internet governance regime, which I argue is necessary in order to capture the dynamics of regime evolution. The framework is based on the structuratio
Innovation is commongly discussed from the perspective of the manufacturing industry. Innovations can be the profitable market introduction of novelties, including new products, improved production techniques and logistics, or new ways of marketing and communication. Innovation can also be used to describe organisational and relational changes. While the service industry differs from the manufactu
Background noise makes listening effortful and may lead to fatigue. This may compromise classroom learning, especially for children with a non-native background. In the current study, we used pupillometry to investigate listening effort and fatigue during listening comprehension under typical (0 dB signal-to-noise ratio [SNR]) and favorable (+10 dB SNR) listening conditions in 63 Swedish primary s
Intrinsically disordered proteins (IDPs) are proteins that, in comparison with globular/structured proteins, lack a distinct tertiary structure. Here, we use the model IDP, Histatin 5, for studying its dynamical properties under self-crowding conditions with quasi-elastic neutron scattering in combination with full atomistic molecular dynamics (MD) simulations. The aim is to determine the effects
The dramatic improvements in Boolean satisfiability (SAT) solving since the turn of the millennium have made it possible to leverage state-of-the-art conflict-driven clause learning (CDCL) solvers for many combinatorial problems in academia and industry, and the use of proof logging has played a crucial role in increasing the confidence that the results these solvers produce are correct. However,
Channel fingerprinting entails associating a point in space with measured properties of a received wireless signal. If the propagation environment for that point in space remains reasonably static with time, then a receiver with no knowledge of its own position experiencing a similar channel in the future might reasonably infer proximity to the original surveyed point. In this article, measurement
