The protons and neutrons that make up the atoms in our Universe are part of a larger group of particles called hadrons. Hadrons have an inner structure consisting of the elementary particles called quarks. The interaction of the quarks is described by the quantum field theory quantum chromodynamics. Quantum chromodynamics predicts a confinement of the quarks within the hadrons, but at large temper
For combinatorial optimization problems that can be formulated as Ising or Potts spin systems, the Mean Field (MF) approximation yields a versatile and simple ANN heuristic, Deterministic Annealing. For problems involving assignments (or permutations), the situation is more complex -- the natural analog of the MF approximation lacks the simplicity present in the Potts and Ising cases. In this arti
In recent years the importance of lobby organizations in the American foreign policy making has increased. One organization that has gained significant influence is the Israel lobby. In this study I present the actors involved in the making of American foreign policy, the relationship America has with Israel and the strategies used by the Israel lobby to gain their influence. I use liberalism to d
Imminent crises and the much-needed transition to a sustainable society bring knowledge about de-implementation to the fore. Using case studies with inspiration from process tracing, and with tools from Charles Tilly’s theory on Durable inequality, we identify mechanisms that generate inequality and counteract the implementation of recovery – and strength-based practices.

The new generation of mobile devices, such smartphones and tablets, make users no longer constrained to traditional devices, such as PCs and laptops, in order to access needed information. This has given rise to an innovation in Business Intelligence (BI) coined mobile BI, which is currently embraced by different organizations. Information systems (IS) innovations are in general accompanied by “bu
Aim: Self-reported cognitive function has been described as an important complement to performance-based measurements but has seldom been investigated in cardiac arrest (CA) survivors. Therefore, the aim was to describe self-reported cognitive function and its association with health status, psychological distress, and life satisfaction.Methods: This study utilised data from the Swedish Register oAim: Self-reported cognitive function has been described as an important complement to performance-based measurements but has seldom been investigated in cardiac arrest (CA) survivors.

The Swedish power system, similar to those of other European countries, is currently transitioning from fossil to renewable. Simultaneously the electrification and digitalization of societies all over the world sets high standards for the availability of power. As a result the power systems experience certain limitations and issues. This can partially be accredited to the decline of available disp

INTRODUCTION: Synaptic dysfunction and loss are pathological hallmarks of neurodegenerative diseases. Neuronal pentraxin 2 (NPTX2), a presynaptic protein involved in synaptic plasticity, has been linked to cognitive decline in Alzheimer's disease (AD) and other neurodegenerative disorders. METHODS: We developed and validated a novel single molecule array (Simoa) for NPTX2 in cerebrospinal fluid, w
Public–Private Partnerships (PPPs) constitute a crucial vehicle in delivering infrastructure. In the transport sector the primary project sponsors are construction companies, which over the last few decades have transformed to strong international actors.

Background: The accumulation of amyloid-β1−42 (Aβ1−42) peptides and phosphorylated-Tau181 (p-Tau181) tangles from the preclinical stages of Alzheimer’s disease (AD) has led to a biological definition of the disease. However, among Aβ1−42-positive individuals, cognitive decline onset varies, and some never develop symptoms. Genetic influences on molecular pathways and their interactions with protei
The Arctic-Boreal region is projected to experience spatially divergent trends in snow depth following climate change. However, the impact of these spatial trends has remained largely unexplored, despite potentially large consequences for the carbon cycle.

Popular Abstract in English Thirty years after the discovery of HIV, the AIDS epidemic is still with us. While the incidence is declining globally and access to anti-retroviral therapy for low- and middle-income countries is improving, the number of new HIV infections is still high. Despite stubborn efforts to design viral immunogens, an effective formulation for the induction of broad and potent Even though the relative contribution of neutralizing antibodies (Nab) to prevent progression to AIDS during HIV-1 infection is still unclear, the induction of broadly NAb directed against HIV-1 through vaccination is considered to represent an important goal for the development of HIV-1 vaccines. Factors contributing to the induction of NAb may include the strength and duration of antigenic stimu

The aim of this study is to investigate how documents regulating municipal work related to housing provision are shaped, and how they utilize concepts of “need” and “demand”. Interviews with municipal planners are conducted to deepen the understanding of the municipal role in Swedish housing provision today. This understanding is crucial in discussions between public and private actors, which are
