In this work, we present a trinification-based grand unified theory incorporating a global SU(3) family symmetry that after a spontaneous breaking leads to a left-right symmetric model. Already at the classical level, this model can accommodate the matter content and the quark Cabbibo mixing in the Standard Model (SM) with only one Yukawa coupling at the unification scale. Considering the minimal
This study examines the relationship between trade and the quality of economic institutions under different political institutions. It uses panel data of 138 countries from 1984 to 2010 and employs instrumental variables and identification through heteroscedasticity to mitigate the problem of endogeneity. The findings suggest that the effect of trade on economic institutions reduces significantly
Perturbation problems for operators with embedded eigenvalues are generally challenging since the embedded eigenvalues cannot be separated from the rest of the spectrum. In this paper we study a perturbation problem for embedded eigenvalues for the bilaplacian with an added potential, when the underlying domain is a cylinder. We show that the set of nearby potentials, for which a simple embedded
Humans have dramatic, diverse and far-reaching influences on the evolution of other organisms. Numerous examples of this human-induced contemporary evolution have been reported in a number of ‘contexts’, including hunting, harvesting, fishing, agriculture, medicine, climate change, pollution, eutrophication, urbanization, habitat fragmentation, biological invasions and emerging/disappearing diseas
To date, approximately 15% of all couples worldwide suffer from infertility. The management include controlledovarian hyper-stimulation of the women with follicle-stimulating hormone (FSH) and semen analysis of the men,prior to in vitro fertilization (IVF) and transfer of the fertilized embryo to the uterine cavity. Approximately 250 000IVF cycles are performed worldwide each year, and as a result
In a sample data system we are essentially restricted to control signals which are constant over the sampling interval. The purpose of this report is to analyze the effect of this restriction. The situation where the admissible control signals are piecewise continuous is used as a reference case and the problem is approached from a variational formulation of the control problem where the object o
This study examines the causal effects of birth weight on two health-related outcomes: inpatient hospitalizations and sickness absences, distinguishing between different diagnoses. Our analysis exploits differences within siblings and within twin pairs, using full population Swedish register data on cohorts born between 1973 and 1995, observed through childhood and in adulthood. In childhood, ther
We derive an expression for the acoustic force density acting on an inhomogeneous fluid with a continuous spatial variation in density and compressibility. A key prediction of our theory, validated by confocal imaging in an acoustofluidic microchip, is that inhomogeneous fluid configurations can be stabilized in the presence of destabilizing forces due to gravity or acoustic streaming flows.
We have characterized the dissolved state of microcrystalline cellulose (MCC) in cold alkali [2.0 M NaOH(aq)] solutions using a combination of small angle X-ray (SAXS) and static light scattering (SLS), (Formula presented.)H NMR, NMR self-diffusion, and rheology experiments. NMR and SAXS data demonstrate that the cellulose is fully molecularly dissolved. SLS, however, shows the presence of large c
Attachment avoidance is associated with deactivation of the attachment system in times of distress, and disengaging from the distressing information as an emotion regulation strategy to restore felt security. The current study investigated how experimentally induced attachment security priming would affect avoidant strategies on attentional level. In a randomized within- between-subjects design, a
This thesis empirically quantifies the impact of promotions on store visits in the Swedish grocery retailing sector with nationally representative panel data on household purchases of ground coffee. Using the potential outcomes framework, the impact is calculated as the difference between outcomes with promotion and their counterfactuals estimated with two regression models. The first model is an
War and violent conflict have always caused uprooting of families and displacement within and across boarders in search of safer grounds. However, human displacement and the security of refugees continue to be underprioritized matters within practices and theories of international security. This study investigates the insecurities of refugees from the subjugated position of women in one of the wor
The spread of pathogens between individuals has important effects on patterns of mortality, behaviour and the genetic structure of populations. One factor that is predicted to influence the transmission of pathogens is the genetic diversity of the host group. Groups of closely related individuals are susceptible to similar pathogens, and hence increase in genetic diversity of the group should decr
In order to enable an effective and efficient adoption of radical innovations in networks, science-based organizations should be aware of the challenges and resistance they may face within their network relationships, resulting from the interconnected structure of high-tech networks as well as the uncertain nature of their radical innovations. By analyzing how nuances of relationship quality influ
The goal of this thesis is to construct p-harmonic functions on the Lie groups U(n), SU(n), U(p,q) and SU(p,q) equipped with the semi-Riemannian metric g(Z,W) = Re trace ( Z W^t ). To do this we present a method which relies on the notion of eigenfunctions. We define these functions and find examples of them defined on the relevant groups. To our knowledge, these eigenfunctions have not been p
