Benthic macroinvertebrates are part of a complex network of interactions. The spatial and temporal scales of the processes that form the basis for these interactions have traditionally restricted their empirical investigation. The first chapter of the manuscript attempts a review of the modelling tools that have been employed for the study of the marine benthos.The implementation of a mechanistic
Due to their dependence on a single crop, agricultural frontiers are often considered to be formed through phases of 'boom and bust'. These phases are closely related to fluctuations in world market prices of the commodity that constitutes the frontier's economic basis. This paper demonstrates how although migration patterns and economic growth are conditioned by world market dynamics, local socio
Natural resource extraction often takes place in locations where communities are not financially well-off and where historically marginalized groups reside. This paper contributes to the policy debate by revealing how corporate social licence tactics enable a model of corporate-community manipulation which is similar across different geographical contexts. Original data gathered between 2016 and 2
Future wireless communications will rely on multiple-input multiple-output (MIMO) beamforming operating at millimeter wave (mmWave) frequency bands to deliver high data rates. To support flexible spatial processing and meet the demands of latency-critical applications, it is essential to use fully digital mmWave MIMO beamforming, which relies on accurate channel estimation. However, ensuring power
I examine the relationship between reproductive success and marker-based relatedness (MBR; inferred from variation at 21 microsatellite loci) of pair-mates in a semi-isolated population of great reed warblers (Acrocephalus arundinaceus) over a 12 year period. There was a negative relationship between egg-hatching success and MBR, but no association between MBR and three other components of fitness
By measuring excited state and charge dynamics in blends of an alternating polyfluorene copolymer and fullerene derivative over nine orders in time and two orders in light intensity, we have monitored the light-induced processes from ultrafast charge photogeneration to much slower decay of charges by recombination. We find that at low light intensities relevant to solar cell operation relatively f
Presence–absence surveys are a commonly used method for monitoring broad-scale changes in wildlife distributions. However, the lack of power of these surveys for detecting population trends is problematic for their application in wildlife management. Options for improving power include increasing the sampling effort or arbitrarily relaxing the type I error rate. We present an alternative, whereby
Popular Abstract in Swedish Teorin för den starka kraften, kvantkromodynamik eller QCD, behandlas här med både perturbativa och icke-perturbativa metoder. Speciellt produktions- och hadroniseringsdynamiken hos tunga partiklar studeras. Dessa partiklar innefattar tunga kvarkar (charm, botten och top), gaugebosoner, leptokvarkar och supersymmetriska partiklar. När tunga långlivade kvarkar (d.v.s. cIn this thesis the phenomenology of Quantum Chromo Dynamics (QCD) is studied in a variety of circumstances from both perturbative and non-perturbative perspectives. The main emphasis is on the production and hadronization of heavy particles, specifically heavy quarks, gauge bosons, leptoquarks and supersymmetric particles. In the hadroproduction of long-lived heavy quarks (i.e. charm and bottom)
From the Management It was so good to see as many of you at the Staff Day last Friday! It was obvious that meeting and have a chat with new and old colleagues in real life was something we have missed for a long time. We learned a lot about each other and urban planning, and there were many nice words written down, you will hear them all being read out loud in the coming Friday fikas. Finally, a h

Parkinson’s disease is a neurodegenerative affliction to which researchers have long striven to find a cure. The human embryo is a source of vital cells used in regenerative medicine, as well as a powerful symbol of life. Using foetal cells from aborted embryos for transplantation to the brains of Parkinson patients is an avenue that has been explored by neuroscientists on and off for the last thi
Software quality engineering is concerned with building software products with required quality and assessing the level of quality. Software processes are important assets in achieving and assessing the software quality. Furthermore the adherence to defined processes is a key issue to having the software engineering under control and to enable process improvement. The software quality assurance (S
Background: Brevican, neurocan, tenascin-C, and tenascin-R are extracellular matrix (ECM) proteins that are mainly expressed in the brain. They play important roles in proliferation and migration of neurons and other cell types in the brain. These ECM proteins may also be involved in various pathologies, including reactive gliosis. Objective: The aim of the study was to investigate if ECM protein
Lean premixed combustion (LPC) is a promising technology for low-NOx emission, while it increases the risk of blowoff at the same time. Experiments and Large Eddy Simulations (LES) on swirl stratified lean-premixed CH4/air flames were performed to study the differences between the stable and near blowoff flame. The flow fields and instantaneous flame structures were measured by simultaneous Partic
To avoid the fierce competition for food, South African ball-rolling dung beetles carve a piece of dung off a dung-pile, shape it into a ball and roll it away along a straight line path. For this unidirectional exit from the busy dung pile, at night and day, the beetles use a wide repertoire of celestial compass cues. This robust and relatively easily measurable orientation behavior has made ball-
Searches for exclusively produced W boson pairs in the process pp(γγ)→pW+W-p and an exclusively produced Higgs boson in the process pp(gg)→pHp have been performed using e±μ final states. These measurements use 20.2 fb-1 of pp collisions collected by the ATLAS experiment at a center-of-mass energy s=8 TeV at the LHC. Exclusive production of W+W- consistent with the Standard Model prediction is foun
Evaluation, prioritization and selection of candidate requirements are of tremendous importance and impact for subsequent software development. Effort, time as well as quality constraints have to be taken into account. Typically, different stakeholders have conflicting priorities and the requirements of all these stakeholders have to be balanced in an appropriate way to ensure maximum value of the
Throughout history packages are used to contain, store and transport goods and products. In early days it was a matter of gathering and storing locally, whereas in today’s global enterprises packaging is an important issue in the operational management in networks of functions and/or divisions, often separated geographically around the world. Packaging has become a part of the process of efficient
Anthropocene has become an environmental buzzword. It denotes a new geological epoch that is human-dominated. As mounting scientific evidence reveals, humankind has fundamentally altered atmospheric, geological, hydrological, biospheric, and other Earth system processes to an extent that the risk of an irreversible system change emerges. Human societies must therefore change direction and navigate
In recent decades, population increase and urban development have led to catastrophic environmental consequences. One of the principal objectives to achieve “sustainable development” is to find suitable landfills. Due to their physical characteristics, which have led to a lack of landfill sites and closeness to water bodies, agricultural fields, and residential areas, the cities of Javanrood, Pave
The language that individuals use for expressing themselves contains rich psychological information. Recent significant advances in Natural Language Processing (NLP) and Deep Learning (DL), namely transformers, have resulted in large performance gains in tasks related to understanding natural language. However, these state-of-the-art methods have not yet been made easily accessible for psychology
