The rich vacuum structure of multi-Higgs extensions of the Standard Model (SM) may have interesting cosmological implications for the electroweak phase transition (EWPT). As an important example of such class of models, we consider a particularly simple low-energy SM-like limit of a recently proposed Grand-Unified Trinification model with the scalar sector composed of two Higgs doublets and a comp
Most students of politics are familiar with Carl Schmitt’s definition of politics as a friend-enemy distinction. Yet, only few know of alternative conceptions of politics in interwar Germany that emphasize cooperation and legality over confrontation and decisionism. To unlock such views, this article examines the work of Hermann Heller, a social-democratic constitutional theorist, and takes a clos
This study provides new quantitative NO concentrations measurements in n-propanol + air and i-propanol + air flames together with a new combustion kinetic model. The heat flux method was employed to stabilize propyl alcohols flames and the initial gas conditions were set to 323 K, 1 atm, and ϕ=0.7-1.4. Saturated laser-induced fluorescence was employed to measure NO concentration in the post-combus
Adaptive as well as innate immune responses contribute to the development of atherosclerosis. Studies performed in experimental animals have revealed that some of these immune responses are protective while others contribute to the progression of disease. These observations suggest that it may be possible to develop novel therapies for cardiovascular disease by selectively modulating such atheropr
This book discusses in detail how Orthodox Christianity was involved in and influenced political transition in Ukraine, Serbia, and Georgia after the collapse of communism. Based on original research, including extensive interviews with clergy and parishioners as well as historical, legal, and policy analysis, the book argues that the nature of the involvement of churches in post-communist politic
Non-ownership models, where firms rather than consumers remain product owners, are advocated as a way for firms to prolong product lifetimes and contribute to a more Circular Economy. However, it has been suggested that such models could actually encourage ‘faster cycling’, meaning earlier product replacement and shorter product lifetimes. Within recent policy discussions, product durability to pr
Solar photovoltaics (PV) has experienced tremendous market growth and has large potential in the urgently needed transition towards a low-carbon energy system. The continued growth of the sector will, however, evoke new sustainability challenges with regard to efficient material use as well as end-of life management of PV products. The aim of this paper is to provide an overview of potential Circu
Unexpected clustering in the orbital elements of minor bodies beyond the Kuiper belt has led to speculations that our Solar system actually hosts nine planets, the eight established plus a hypothetical 'Planet Nine'. Several recent studies have shown that a planet with a mass of about 10 Earth masses on a distant eccentric orbit with perihelion far beyond the Kuiper belt could create and maintain
Within the field of emergency management and fire response, risk and quality are conceptualized to some degree in every response effort. Quality is viewed as a relatively new concept within the field of emergency management and fire response. Whereas, within this same field the concept of risk is more commonly discussed. In this paper, the commonalities between risk and quality are identified and
Feedback control is increasingly being applied in server systems to make them more robust and efficient. This includes managing quality of service, minimizing power consumption, and adapting to varying workloads. Successful adaptation and control in turn relies on accurate tracking of workload variations and timely detection of changes in the computing infrastructure. Given that server systems are
Metallurgical debris is by far the most informative source material for studying the metal craftsmanship ofthe past. In comparison to the finished objects, which has attracted far more attention in archaeologicalresearch, debris material are more or less confined to the original workshop sites and hence provide directevidence as to production volume and quality, site organization, artisanal skill
We considered nonlinear solvers inside implicit time integration schemes for the time dependent compressible Navier-Stokes equations. The existing solvers turn out to be adequate, but amenable to significant improvements. Regarding multigrid schemes, we demonstrated that reoptimizing a multigrid scheme for the case of a time dependent equation leads to significant improvements in convergence speed
Results of the first experiment on studying the radiation spectra of electrons with energy 192 7 MeV in diamond and silicon crystals at axial and plane orientation performed at the MAX-lab facility were presented. At these orientation the particle's motion can be both regular, when axial and planar channeling are possible, and chaotic, when the coherent electron interaction with single strings rev
Historically, private initiative has always been of great significance for the arts. In most Europe-an countries the government took over from the private initiative after World War II. However, private initiative never completely disappeared, this is also true in the second half of the 20th century in which government subsidies were the dominant factor in the funding of the arts and cultural heri
Giant molecular clouds (GMCs) are believed to affect the biospheres of planets as their host star passes through them. We simulate the trajectories of stars and GMCs in the Galaxy and determine how often stars pass through GMCs. We find a strong decreasing dependence with Galactocentric radius, and with the velocity perpendicular to the Galactic plane, Vz. The XY-component of the kinematic heating
Context: Obesity is a frequent manifestation of hypothalamic damage from a craniopharyngioma (CP). It is not yet clarified whether the obesity is due to alterations in energy expenditure, i.e. basal metabolic rate (BMR) and physical activity, or to increased energy intake (EI). Objective: The aim was to investigate whether energy expenditure and EI differed between childhood onset CP patients and
