Protein kinase C (PKC) plays a prominent role in immune signaling, and the paradigms for isoform selective signaling are beginning to be elucidated. Real-time microscopy was combined with molecular and biochemical approaches to demonstrate a role for PKC-epsilon in Fcgamma receptor (FcgammaR)-dependent phagocytosis. RAW 264.7 macrophages were transfected with GFP-conjugated PKC isoforms, and GFP m
Roundtable presentation for: The Orient There and Back Again. Multidisciplinary Reflections on MENA Research and Sweden 1974-2024 (roundtable organised by Annika Rabo). Chair: Rouzbeh Parsi (Swedish Institute of International Affairs)Participants: Marianne Boqvist (Folke Bernadotte Academy), Torsten Janson (Lund University), Pernilla Myrne (University of Gothenburg), Annika Rabo (Stockholm Univers
When incorporating anisotropic materials, planar microcavities can give rise to exceptional points, i.e. propagation directions along which two otherwise polarization-split photonic modes degenerate in energy and broadening. They are non-Hermitian degeneracies revealing complex-square-root topology and chiral eigenstates. We show computations and experiments on ZnO-based microcavities.
Background: In the context of the investigation of the quark gluon plasma produced in heavy-ion collisions, hadrons containing heavy (charm or beauty) quarks play a special role for the characterization of the hot and dense medium created in the interaction. The measurement of the production of charm and beauty hadrons in proton-proton collisions, besides providing the necessary reference for the
Popular Abstract in Swedish Avhandlingens bidrag ligger inom området för Markov regimskiftesmodeller i tidsserieanalys. Den består av fem separata uppsatser som specifikt undersöker två statistiska frågeställningar, samt applicerar metodologin på fyra olika makroekonomiska områden. De två huvudsakliga statistiska bidragen rör (i) utvecklandet av ett flexibelt test baserat på simulering för att utrThis dissertation studies statistical properties and applications of the Markov switching models for economic time series in five separate papers. The two main statistical themes are (i) the task of choosing the number of states to use in the model, and (ii) inference on time-varying transition probabilities. Our empirical applications span a wide array of topics in international finance and macro
Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. AR, ARMA, ARMAX and Box-Jenkins-type models. An optimal alarm system is characterized by having the least number of false alarms, fo
Den svenska attityden till Scientologykyrkan har sedan 1970-talet ändrats från fördömande som icke-religion (Socialstyrelsen) till formell acceptans som religionssamfund med vigselrätt. Orsaker är religionslandskapets förändring genom immigration, ny lagstiftning om trossamfund, som definierats öppet utifrån syftet att anordna gudstjänst, samt en mera positiv socialpolitisk inställning till privat
Power system voltage security assessment is generally applied by considering the power system loadability surface. For a large power system, the loadability surface is a complicated hyper-surface in parameter space, and local approximations are a necessity for any analysis. Unfortunately, inequality constraints due to for example generator overexitation limiters, and higher codimension bifurcation
Hierarchical mobility management schemes such as HMIP and cellular-IP have been shown to be effective in providing low latency handoff in mobile networks. In this paper, we investigate the suitability of hierarchical mobility management schemes in Wireless Mesh Networks (WMN) and find that they are not directly suitable since MWNs have graph based topologies rather than tree based topologies. Beca
Popular Abstract in Swedish Vanlig bagerijäst, Saccharomyces cerevisiae, används i storskalig etanol framställning från majs och sockerrör. Användandet av dessa råvaror för etanolproduktion konkurerar dock med framställning av spannmål för föda och djurhushållning. Den här avhandlingen har syftat till att få bagerijäst att använda sockerarten xylos, som finns i stora halter i restprodukter från skBaker’s yeast, Saccharomyces cerevisae, has been engineered to utilize the pentose sugar xylose present in lignocellulose biomass for the production of ethanol. Currently ethanol production from xylose is slow which limits the implementation of said strains in industrial production. This thesis describes the investigation of several metabolic aspects that control the rate of xylose utilization by
Early Warning Systems (EWS) are crucial for safeguarding communities, but are vulnerable to failure due to a technocratic focus that excludes local communities. This thesis closes the gap between normative participatory principles and practical implementation by exploring the entry points or challenges that affect community participation. Adopting a complexity theory lens, the study conducts a qua
Norge drabbas årligen av hundratals jordskred vilket leder till betydande ekonomisk skada och fara för liv. Därför bedriver norska myndigheter och forskningsinstitutioner omfattande forskning om jordskred och vidtar åtgärder för att övervaka, modellera och slutligen mildra konsekvenserna av och förebygga dessa. Som en del av sitt arbete underhåller norska vattenresurs- och energimyndigheten en natNorway experiences hundreds of landslides annually which leads to significant economic losses and poses a threat to human life. Therefore, Norwegian authorities and scientific institutions are conducting extensive research and take measures in the fields of documenting, modelling and ultimately mitigating and preventing landslides. As part of its work, the Norwegian Water Resources and Energy Dire
