We introduce two novel joint radio-frequency (RF)-baseband designs for receivers in a MIMO system with Nt transmit antennas, Nr receive antennas, but only L < Nr RF chains at the receiver. The joint design introduces an RF pre-processing matrix that processes the signals from the different antennas, and is followed by selection (if necessary), down-conversion, and further processing in the baseban

SASE saturation was recently achieved at the Advanced Photon Source's SASE FFL in the low-energy undulator test line at 530 nm and 385 urn. The electron beam microbunching becomes more and more prominent until saturation is achieved. This bunching causes nonlinear harmonic emission that extends the usefulness of a SASE system in achieving shorter FEL wavelengths for the same electron beam energy.

We assessed a total range of peripheral thyroid hormone fractions, binding globulins, and thyroid-active antibodies in 37 medication-free, violent or sexual offenders, aged 17-45 years, to describe possible mechanisms involved in the thyroid metabolism of aggressive men. The ratio between T3 and T4 correlated with ratings of psychopathy, indicating increased peripheral deiodination as a biological

Popular Abstract in Swedish I denna avhandling studeras en resonant omvandlare. Detta är en elektrisk krets som amvandlar likspänningar från en nivå till en annan. För att styra detta system, måste man förstå dess egenskaper. Min uppgift har varit att undersöka huruvida systemet innehåller s.k. gränscykler (självsvängningar) respektive chattering (extremt snabba självsvängningar). Vissa av dessa gIn this thesis existence and uniqueness of limit cycles are shown for a resonant converter, by extending Poincaré-Bendixson theory to non-smooth vector fields. We discuss relevant control theory and the role of simulations.

The history of the term "parody" is sketched, and different theoretical traditions defining parody is described. The traditions are structured according to the theorist's description of the function of parody. Among these theories, Bachtin's theory of parody as a dialogical text has a prominent position.

1. The structure of chondroitin/dermatan and heparan-sulphate chains from various proteoglycan populations derived from cultured human skin fibroblasts have been examined. Confluent cell cultures were biosynthetically labelled with [3H]-glucosamine and 35SO4(2-), and proteoglycans were purified according to buoyant density, size and charge density [Schmidtchen, A., Carlstedt, I., Malmstrom, A. &am

Accurate dosimetric investigations are important to be able to fulfill the ambition of radiation protection in nuclear medicine and to minimize the radiation burden to the patient. This paper presents human radiation absorbed dose estimates following an administration of an 111In-labeled anti-CEA-F(ab')2 (BW431/31) based on detailed biodistribution and elimination data in a rat model. Animals were

The main objective of the paper is to support and illustrate recent theoretical results on the mathematical modelling of the secondary clarifier. A new settler model is compared with a traditional layer model by means of numerical simulations. Emphasis is put on the numerical solution's ability to approximate the analytical solution of the conservation law written as a non-linear partial different

Control of emission by intermolecular fluorescence resonant energy transfer (IFRET) and intermolecular charge transfer (ICT) is investigated with the quantum-chemistry method using two-dimensional (2D) and three-dimensional (3D) real space analysis methods. The work is based on the experiment of tunable emission from doped 1,3,5-triphenyl-2-pyrazoline (TPP) organic nanoparticles (Peng, A. D.; et a

Magnetotransport in GaAs/AlAs/GaAs single-barrier heterostructures, incorporating unintentional donors in the barrier, is studied. Resonant tunneling is observed through the quasiconfined states in the AlAs layer which originate from the X-XY and X-Z conduction-band minima and through two distinct states of the donors bound to the X-XY and X-Z valleys. This allowes us to determine directly the bin

In this book the authors discuss globalisation, the use of new technology and its effects on higher education. Four old universities in Europe (Bologna, Cambridge, Leuven and Lund) are used as illustrations of different approaches to managing a changing environment. The authors focus on questions like: Differences in organisational structure and strategic choices, how do they affect internationali
