The European species of Euplectrus Westwood are comprehensively treated for the first time, using a combination of morphological and DNA data (CO1, the barcode). Ten species are included, seven already described: E. bicolor (Swederus), E. flavipes (Fonscolombe), E. intactus Walker, E. liparidis Ferrière, E. maculiventris Westwood, E. nigriceps Ferrière, E. phthorimaeae Ferrière, and three new spec

Building the Tree of Life (ToL) is a major challenge of modern biology, requiring advances in cyberinfrastructure, data collection, theory, and more. Here, we argue that phylogenomics stands to benefit by embracing the many heterogeneous genomic signals emerging from the first decade of large-scale phylogenetic analysis spawned by high-throughput sequencing (HTS). Such signals include those most c

Between the 2014 and 2018 Swedish parliamentary elections, the vote share of the anti-immigration Sweden Democrats increased significantly. To evaluate the possibility of a causal link between immigration and the right-wing populist vote, this paper uses data from a nationwide policy experiment, under which refugees are allocated randomly to every municipality in the country, creating exogenous va

Denna litteraturstudie är en del av projektet ”Smart tillgänglighet i bytespunkter” som är ett gemensamt forskningsprojekt mellan K2 och Mistra SAMS. Studien syftar till att få en bild av vilken forskning som finns angående bytespunkters planering och om det redan finns forskning som kopplar ihop bytespunkter och mobilitetstjänster. Vidare är ett undersyfte att ta reda på vad som är viktigt ur ett

Lera består utav små finkorniga lermineraler, vilka utgörs till stor del av elektrostatiskt laddade nanopartiklar, även kallade lerplattor. En lerplatta har en tjocklek på en miljarddels meter och dess diameter kan variera alltifrån fem till tusen gånger större än tjockleken, vilket kan jämföras med ett A4-ark, där kortsidan är tusen gånger större än tjockleken. Denna storleksskillnad ger upphov tClay minerals consist of anisotropic nanoplatelets where the majority of the clay minerals are highly charged, and thus, swell in aqueous solution. The structure and swelling depend on the type of clay mineral, and also on the ionic composition, and temperature. The natural clay mineral montmorillonite have been studied both theoretically and experimentally. Theoretically, coarse-grained models ha

Efter en landreform, som genomfördes i slutet av 40- och i början av 50-talet, blev de flesta taiwanesiska bönderna hemmansägare och odlade marken på små lantegendomar. Denna efterkrigsreform banade väg för en ekonomisk utveckling som väsentligt påverkade och förändrade bondesamhället. När det taiwanesiska jordbruket visade tecken på stagnation på 1970-talet, förändrades böndernas syn på markinnehAfter post-war land reform that took place between 1949 and 1953, most Taiwanese farmers became owner-cultivators working on small landholdings. Post-war land reform paved the foundation for economic development and industrialization, processes that squeezed the agricultural sector and created changes in farming villages. When Taiwanese agriculture showed signs of stagnation in the 1970s, farmers’

Previous research has suggested beneficial effects of vitamin D on both breast cancer risk and prognosis. The overall aim of this research project was to investigate associations between vitamin D and breast cancer. The population-based prospective cohort, the Malmö Diet and Cancer Study, recruited 17,034 women in the first half of the 1990s. Studies in in the current thesis are based on blood sam

The focus of this article is to undertake a comparative analysis of multi-step-ahead linear multivariate predictors. The approach considered for the estimation will be based on geometrically reliable linear algebra tools, resorting to subspace identification methods. A crucial issue is quantification of both bias error and variance affecting the estimate of the prediction for increasing values of

This paper presents theory, algorithms and validation results for system identification of continuous-time state-space models from finite non-uniformly sampled input-output sequences. The algorithms developed are methods of model identification and stochastic realization adapted to the continuous-time model context using non-uniformly sampled input-output data. The resulting model can be decompose

The paper suggests conditions for presence of quadratic Lyapunov functions for nonlinear observer based feedback systems with an input nonlinearity in the feedback path. Provided that the system using state feedback satisfies the circle criterion (i.e., when all states can be measured), we show that stability of the extended system with output feedback control from a (full state) Luenberger-type o

The theory for motion planning and feedback stabilization of periodic orbits has regained a large interest during the last couple of years, with applications in, for instance, biped locomotion. The analysis of zero-dynamics after partial feedback linearization has been one means. More recently, the introduction of virtual holonomic constraints has offered also the design tools for these type of sy

Group A Streptococcus (GAS) is a common and versatile human pathogen causing a variety of diseases. One of the many virulence factors of GAS is the secreted pore-forming cytotoxin streptolysin O (SLO), which has been ascribed multiple properties, including inflammasome activation leading to release of the potent inflammatory cytokine IL-1β from infected macrophages. IL-1β is synthesized as an inac

This paper presents the design and characterization of millimeter-wave (28/38 GHz), circularly polarized (CP) active antennas, suitable for the future 5G services. By augmenting the modelling capabilities of commercially available nonlinear CAD tools, the active antenna design can simultaneously optimize figures of merits for both radiation and non-linear (NL) performance. The radiating part is co

There is a significant infrastructure in the world for using liquefiedpetroleum gas (LPG). The fuel is used in many applications, spanningfrom heating to chemical processes as well as a vehicle fuel. To be able touse this infrastructure also after a transition from fossil to renewablesources, a technology for producing LPG from such resources (glycerol,cellulose etc.) is being developed. This repo

För att undersöka och utvärdera temperaturfördelningar och efterföljande lastfall i betongkonstruktioner kan exempelvis temperatursimuleringar användas. Sådana simuleringar har gjorts i flera tidigare studier med hjälp av väderdata som mätts upp i närheten av den konstruktion som studeras. Denna metod har dock begränsningar i och med att viktiga klimatparametrar som globalstrålning och långvågig sTo study and evaluate temperature distributions and subsequent load cases in concrete structures it is common to use thermal simulations. Such simulations have been performed in multiple previous studies using weather data measured in the vicinity of the studied object. However, this method has limitations, since important factors such as solar radiation and longwave heat radiation are only measur
