Using the one-loop Coleman-Weinberg effective potential, we derive a general analytic expression for all the derivatives of the effective potential with respect to any number of classical scalar fields. The result is valid for a renormalisable theory in four dimensions with any number of scalars, fermions or gauge bosons. This result corresponds to the zero-external momentum contribution to a gene
Co-occurrence of closely related species can cause behavioral interference in mating and increase hybridization risk. Theoretically, this could lead to the evolution of more species-specific mate preferences and sexual signaling traits. Alternatively, females can learn to reject heterospecific males, to avoid male sexual interference from closely related species. Such learned mate discrimination c
We have shown recently that PrkC, which is involved in developmental processes in Bacillus subtilis, is a Ser/Thr kinase with features of the receptor kinase family of eukaryotic Hanks kinases. In this study, we expressed and purified from Escherichia coli the cytoplasmic domain of PrkC containing the kinase and a short juxtamembrane region. This fragment, which we designate PrkCc, undergoes autop
An isolated, yet virtually intact contour feather(FUM-1980) from the lower Eocene Fur Formation of Denmarkwas analysed using multiple imaging and moleculartechniques, including field emission gun scanning electronmicroscopy (FEG-SEM), X-ray absorption spectroscopy andtime-of-flight secondary ion mass spectrometry (ToF-SIMS).Additionally, synchrotron radiation X-ray tomographicmicroscopy (SRXTM) waAn isolated, yet virtually intact contour feather (FUM-1980) from the lower Eocene Fur Formation of Denmark was analysed using multiple imaging and molecular techniques, including field emission gun scanning electron microscopy (FEG-SEM), X-ray absorption spectroscopy and time-of-flight secondary ion mass spectrometry (ToF-SIMS).

An experimental setup for characterizing the magnetic field of MRI RF coils was proposed and tested. The setup consisted of a specially configured 3D-printer, a network analyzer and a mid-performance desktop PC. The setup was tested on a single loop RF coil, part of a phased array for fetal imaging. Then, the setup was used for determining the magnetic field characteristics of a high-pass birdcage
Background: The success of randomized-controlled stroke trials is dependent on the recruitment and retention of a sufficient number of patients, but fewer than half of all trials meet their target number of patients. Methods: We performed a search and review of the literature, and conducted a survey and workshop among 56 European stroke trialists, to identify barriers, suggest methods to improve r
Purpose - The dimple is adopted into a pin fin wedge duct which is widely used in modern gas turbine vane cooling structure trailing edge region. The purpose of this paper is to study the effects of dimple depth and duct converging angle on the endwall heat transfer and friction factor in this pin fin wedge duct. Design/methodology/approach - The study is carried out by using the numerical simulat
This paper proposes a discrete-time hazard regression approach based on the relation between hazard rate models and excess over threshold models, which are frequently encountered in extreme value modelling. The proposed duration model employs a flexible link function and incorporates the grouped-duration analogue of the well-known Cox proportional hazards model and the proportional odds model as s
This dissertation deals with the effects of nuclear structure on the α-decay properties, and on the fission-yielddistributions from the decay of heavy nuclei. The nuclear-structure and decay properties of superheavynuclei is one of the central topics for investigation. α decay is treated in a microscopic approach employingSkyrme-Hartree-Fock-Bogoliubov wave functions to describe the formation of aThis dissertation deals with the effects of nuclear structure on the α-decay properties, and on the fission-yielddistributions from the decay of heavy nuclei.

Denna rapport handlar om den regionala ekonomiska strukturomvandling som ägt rum i Västra Götaland och Skåne sedan 1990-talet, och om den fortsatta automatiseringens framtida regionala avtryck på svenska lokala arbetsmarknader. Rapporten beskriver och gör en sammanfattning av den debatt som på senare år varit intensiv om automatiseringens framtida effekter på arbetsmarknaden. Med utgångspunkt i de
De regionala klyftorna i Sverige har ökat sedan 1980-talet. Den här utvecklingen innebär politiska utmaningar. Stora regionala ojämlikheter hotar sammanhållningen i samhället och kan minska legitimiteten i det kommunala omfördelningssystemet. Skriften sätter in de senaste 30 årens ökande regionala skillnader i ett historiskt perspektiv. För detta ändamål presenteras nya dataserier på BNP per capit
How can we shape our urban development towards sustainable and prosperous futures? This course explores sustainable cities as engines for greening the economy in Europe and around the world. We place cities in the context of sustainable urban transformation and climate change. We connect the key trends of urbanization, decarbonisation and sustainability. We examine how visions, experiments and inn
Studies have shown that all Swedish municipalities are involved in cooperation with other municipalities, and most frequent in soft forms like agreements. Often each municipality have full control of its activities and then join forces with others on the margin. However, in this chapter it is showed that this situation is undergoing a change. Municipalities facing new a new landscape are looking f
The substitution kinetics of Me2PhP in cis-Pt(SiMePh2)2(PMe2Ph)2 (1) by the chelating ligand bis(diphenylphosphino)ethane has been followed at 25.0 °C in dichloromethane by stopped-flow spectrophotometry. Addition of the leaving ligand causes mass-law retardation compatible with a dissociative process via a three-coordinate transition state or intermediate. Exchange of Me2PhP in 1 has been studied
