This thesis investigates ultracold bosonic systems using an extended mean-field formalism with a focus on their superfluid and supersolid properties. The dissertation comprises five chapters and four articles, where the chapters provide some background to the research put forward in articles.Paper I demonstrates the existence of multiple singly-quantized vortices in two-dimensional droplets made o
Changes in nutrient bioavailability due to increased loading of dissolved organic matter (DOM) may impact boreal freshwaters. Yet, the relative bioavailability of carbon (C), nitrogen (N), and phosphorus (P) associated with terrestrial DOM remains poorly understood. We applied short-term bioassays with natural bacterial inocula to determine seasonal variation in bioavailable organic nutrient pools
Since 2011, Moroccan civil society actors have experienced an important political opening that has allowed them to play a much more direct and influential role in the process of policy-making. The National Dialogue that has taken place between the government and civil society in the writing of different pieces of legislation represents a demonstrable step towards increased participation and legiti
The concept of ‘patient involvement’ is highlighted in healthcare. However, hindrances can prevent its implementation. This article explored how ‘patient involvement’ is understood and on what ideas this understanding is based through a critical textual analysis of the European document on patient involvement in health systems using a Fairclough-inspired critical discourse analysis. The findings s
In the informal settlements of warm humid climates, where the majority of urbanites spend most of their time outdoors, a conducive thermal environment is crucial for their social and economic well-being. The overall aim of this thesis is to increase knowledge and understanding of outdoor thermal comfort in informal settlements in the warm and humid climate of Dar es Salaam, Tanzania. Urbanites’ th
OBJECTIVES: Coronary artery calcium score (CACS) is a marker of subclinical atherosclerosis. However, there is little data related to the association between arterial stiffness and CACS in the general population. The aim of this study was to explore the association between carotid femoral-pulse wave velocity (c-f PWV), a widely accepted marker of arterial stiffness, and CACS.METHODS: Participants
This chapter provides a survey of the existing quantitative research on antisemitism and social media. Through doing so, it argues that the sheer quantity of antisemitism on social media is much less than commonly perceived. In addition, the chapter argues that quantitative research often neglects counter-narratives calling out antisemitism, which are an important counterpoint to include in antise
Whilst network coordination games and network anti-coordination games have received a considerable amount of attention in the literature, network games with coexisting coordinating and anti-coordinating players are known to exhibit more complex behaviors. In fact, depending on the network structure, such games may even fail to have pure-strategy Nash equilibria. An example is represented by the we
We study extensions of the classical SIR model of epidemic spread. First, we consider a single population modified SIR epidemics model in which the contact rate is allowed to be an arbitrary function of the fraction of susceptible and infected individuals. This allows one to model either the reaction of individuals to the information about the spread of the disease or the result of government rest
The Bonacich centrality is a well-known measure of the relative importance of nodes in a network. This notion is, for example, at the core of Google’s Page Rank algorithm. In this paper we study a network formation game where each player corresponds to a node in the network to be formed. The action of a player consists in the assignment of m out-links and his utility is his own Bonacich centrality
We study deterministic continuous-time lossy dynamical flow networks with constant exogenous demands, fixed routing, and finite flow and buffer capacities. In the considered model, when the total net flow in a cell —consisting of the difference between the total flow directed towards it minus the outflow from it— exceeds a certain capacity constraint, then the exceeding part of it leaks out of the
