We consider an ultra-wide bandwidth system using reduced-complexity RAKE receivers, which are based on either selective (called SRake) or partial (called PRake) combining of a subset of the available resolved multipath components. We investigate the influence of the spreading bandwidth on the system performance using the two considered types of RAKE receivers. We show that, for a fix number of RAK

Popular Abstract in Swedish ?DNA-mikromatriser eller genchips? är idag väletablerade verktyg inom biologisk forskning och klinisk diagnostik. Genmikromatriser kan exempelvis användas för att i mikroskala studera genetiska skillnader mellan sjuka och friska vävnader. Informationen som då erhålls kan ge värdefulla upplysningar om sjukdomens natur och användas vid utveckling av nya läkemedel. GenernAntibody-based microarrays are among the novel class of rapidly evolving proteomic technologies. In recent years, antibody microarrays have emerged as a unique tool for high-throughput protein expression profiling with great promise within biomedicine and a wide range of potential applications, including disease diagnostics and biomarker discovery. In order to evolve the technology from small dedi

A strategy for feedback control of the glucose feed rate in cultivations of E.coli is discussed. By making probing pulses in the feedrate it is possible to detect and avoid undesirable by-productformation using a standard dissolved oxygen sensor. The feasibility of an improved and simplified probing algorithm is demonstrated by simulations as well as laboratory-scale experiments.

Popular Abstract in English All living things somehow communicate with each other. Cell-to-cell communication, or signalling, occurs on the molecular level, regulating the body’s activities and coordinating various cell actions and is thereby valuable for realizing cell as well as system functions. Errors in the cellular transferred information may induce diseases such as cancer and autoimmune disGlypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediatin

The heavy recession in Sweden during the first half of the nineties led to a very difficult situation for young people with a weak position on the labour market. Around a third of the youths born in the mid seventies had received social welfare benefits before the age of 24. Despite the recovery in the Swedish economy a group of young adults, now in their thirties, simply can not find a way to eit

Popular Abstract in Swedish Växters fenologi påverkar ekosystemens funktion och tjänster, och återkopplar till klimatet genom att påverka utbytet av kol, vatten och energi mellan atmosfär och ekosystem. Under de senaste decennierna har växternas fenologi studerats i allt större omfattning, men fortfarande är osäkerheten stor och enighet saknas om klimatets inverkan på fenologi och förändringar övePlant phenology exerts major influences on carbon, water, and energy exchanges between atmosphere and ecosystems, provides feedbacks to climate, and affects ecosystem functioning and services. Great efforts have been spent in studying plant phenology over the past decades, but there are still large uncertainties and disputations in phenology estimation, trends, and its climate sensitivities. This

A modified version of the delayed single-photon self-interference experiment is performed using a sample of Pr:Y₂SiO₅ for detecting the interference pattern. Instead of using a beam splitter and two spatially separated paths for the light to travel towards the material, acousto-optic modulators are used to create two light pulses and let the pulses travel along the same path

This review contains an overview of strong interaction effects in weak decays starting with a historical introduction. It contains a short overview of semileptonic decays and their relevance for measuring CKM matrix elements. The main part is devoted to the theoretical calculation on nonleptonic matrix elements relevant for K⁰-K⁰bar mixing and K to pi pi decays. It concludes

In this paper, we present a statistical model for the ultra-wideband (UWB) channel in an industrial environment. Based on a set of measurements in a factory hall, we find that the abundance of metallic scatterers causes dense multipath scattering. This can be seen to produce mostly a Rayleigh distributed small-scale fading signal, with only a few paths exhibiting Nakagami distributions. For the po
