An analysis of long-term fading properties of 4×4 CW MIMO channels is presented in this paper. The main focus has been on the long-term variability of MIMO channels in urban cellular environments, with emphasis on the decorrelation distance over mid range distances along the mobile trajectory for different base station antenna heights. A model that characterizes the decorrelation distance at diffe

Based on detailed 2D and 3D numerical radiation hydrodynamicscalculations of time-dependent compressible convection, we have studiedthe dynamics and thermal structure of the convective surface layers of aprototypical late-type M-dwarf at Teff=2800 K, and log g=5.0with solar chemical composition. The thermal structure of the atmosphereis dominated by molecular absorption, the formation of dust grai

Popular Abstract in Swedish Modeller för proteinveckning utvecklas och tillämpas på peptider och små proteiner som har både α-helix- och β-blad-struktur. Energifunktionerna, i vilka effektiva hydrofobicitetskrafter och vätebindningar är de två centrala termerna, är helt sekvensbaserade och har medvetet hållits enkla. Den geometriska representationen av proteinkedjorna är däremot detaljerad och harModels for potein folding are developed and applied to peptides and small proteins with both α-helix and β-sheet structure. The energy functions, in which effective hydrophobicity forces and hydrogen bonds are taken to be the two central terms, are sequence-based and deliberately kept simple. The geometric representations of the protein chains are, by contrast, detailed and have torsion angles as

Chondroitin (CS) and dermatan sulphate (DS) are socalled glycosaminoglycans (GAG) that are covalently attached to various type of proteins forming a subgroup within the diverse proteoglycan (PG) family. The PGs studied in this thesis are mostly extracellularly located and include aggrecan, biglycan and decorin. The CS and DS chains both consist of repeating disaccharides of the type (hexuronic aci

This chapter considers the problem of estimation of the transfer function of a continuous-time dynamic system in the presence of colored noise. Whereas parameter estimation can be made by means of a discrete-time maximum-likelihood algorithm, an operator transformation permits a continuous-time model parameterization. The method is useful in cases where it is important to estimate the coefficients

The paper introduces a probabilistic semantics for the paraconsistent temporal logic Ab presented by the authors in a previous work on future contingents. Probabilistic concepts help framing two possible interpretations of the logic in question - a `subjective' and an `objective' one - and explaining the rationale behind both of them. We also sketch a proof-method for Ab and address some considera

Popular Abstract in Swedish Signaler om smärta och känsel löper från receptorer ute i kroppen genom olika typer av nervfibrer in till ryggmärgens bakhorn och till trigeminuskärnorna i hjärnstammen. Där kopplas signalerna via synapser vidare till nervceller som leder signalerna upp till hjärnan, så att vi blir medvetna om vad som händer i kroppen. På sin väg till hjärnbarken kopplas signalerna om yThe amino acid glutamate is today regarded as the main fast excitatory neurotransmitter in the central nervous system and a large body of evidence support that glutamate serves as a neurotransmitter in primary afferent terminals in the spinal cord. Previous evidence also suggests that the closely related amino acid aspartate may serve a similar role in some primary afferent terminals. However, the
