We envision the use of large intelligent surface (LIS) technology, which is a promising concept that goes beyond massive multiple-input multiple-output (MIMO), for positioning applications due to its ability to focus energy in the 3D space. The Cramér-Rao lower bounds (CBLBs) for positioning using a LIS which can resolve amplitude and phase with full resolution have already been determined in the
The case is about grassroots monetary innovations carried out for social purposes. Through the case of the Kenyan community currencies the reader gets an insight into the social challenges these currencies aim to address, the effort that goes into designing these local monies as well as into organising the communities that use them. The reader is presented with the practical challenges faced by th
Hanseatic League of Science (HALOS)Hanseatic League of Science (HALOS) is a unique cross-border ÖKS interreg project with 15 official partner organizations including research institutes in Denmark, Sweden and Germany. Through HALOS the Life Science research and innovation ecosystems will get access to crossborder cooperation platforms where academia and industry can meet. Key stakeholders will be
Connecting the complementary facilities MAX IV & ESS with DESY & European X-FEL creates synergy and a globally unique infrastructure region with fantastic opportunities for innovation and research not least in Life Science. Through Hanseatic League of Science (HALOS) the Life Science research and innovation ecosystems is given a joint platform to take advantage of the facilities and a tool
The increase of plasma levels of high-density lipoproteins and Apolipoprotein A-I (ApoA-I), its main protein component, has been shown to have a positive action on glucose disposal in type 2 diabetic patients. The current study investigates the unexplored function of ApoA-I to prime beta cells for improved insulin secretion. INS-1E rat clonal beta cells as well as isolated murine islets were used
In this paper we analyse the transmission of the electromagnetic field through a dielectric, spherical shell - a simple radome. The source is located inside the shell and consists of a vertical or horizontal electric dipole or a simple array of electric dipoles. A circular PEC (perfect electric conductor) disk is located at the center of the shell and simulates a ground plane. The effect of the sh
Knäleden är kroppens största led och är påtagligt komplicerad. Den utsätts dagligen för stora krafter vid såväl böj och vridrörelser som stötkrafter vid stegisättning. För att den skall fungera optimalt måste flera olika komponenter samverka. Brosket som bekläder benändarna bidrar med stötdämpning och ger en mycket låg friktion vid rörelse. Flera olika ligament och muskler som löper över leden bid
In this volume of “Lecture Notes in Intelligent Transportation and Infrastructure”, we are pleased to present the proceedings of the International Conference “Vision Zero for Sustainable Road Safety in Baltic Sea Region”, which took place in Vilnius, Lithuania, from 5 to 6 December 2018.

The miIn this volume of “Lecture Notes in Intelligent Transportation and Infrastructure”, the proceedings of the International Conference “Vision Zero for Sustainable Road Safety in Baltic Sea Region”, which took place in Vilnius, Lithuania, from 5 to 6 December 2018, are presented. The mission of the conference was to promote a more comprehensive approach supporting new ideas, technologies, theories, i
Abstrakt. Ett etablerat MP2RAGE-protokoll för semikvantitativ strukturell hjärn-MRI överfördes frånen 7T MR-skanner till en annan leverantör med jämförbar hårdvara, men motsatt polaritet. På det härsystemet, kan skanningstiden reduceras från 11 till 8 minuter genom elliptisk k-space-sampling.

An established MP2RAGE protocol for semi-quantitative structural brain MRI was transferred from one 7T MR scanner to that of another vendor featuring comparable hardware, but opposite polarity. On this system, the scan time could be reduced from 11 to 8 minutes by elliptical k-space sampling. Three configurations of radio-frequency (RF) transmission were compared (single channel with qu
The objective is to study the effect of high voltage pulses on living cells to find the most effective combination of physical parameters to be used in tumour therapy. Four parameters that affect the cell survival are the pulse shape, electric field strength, pulse length and the number of pulses and their cell killing effect were investigated in this work. High voltage square wave or exponentiall
Objective. To report the first clinical evaluation of a new balloon endometrial, thermal destruction system Cavaterm®, for outpatient treatment of menorrhagia. Design. To elucidate possible technical problems during treatment, to evaluate how the patients tolerated the treatment and to judge which patients were suitable for this form of treatment. Main outcome measures. Measurements of bleeding vo
Thermotherapy of the uterus has emerged as an alternative to hysterectomy in the treatment of menorrhagia, from whence it follows that the thermal properties of uterine tissue have become of importance. This study presents measurements of the thermal conductivity and the water content of uterine tissue in vitro. A steady-state thermal conductivity apparatus, based on the comparison of test samples
Objective To estimate, using numerical calculations, the depth of tissue damage in the uterus following balloon thermal endometrial destruction. Design A parameter, therapeutic depth, was defined. This was the maximum depth into the uterine myometrium, from the uterine cavity, at which a predefined temperature was reached after a certain time and with a constant intracavitary temperature. Setting
This study tested the effect of repeated intratumoural injection with recombinant interleukin-2 (rIL-2) and tumour-infiltrating lymphocytes (TILs) on inhibition of growth of breast cancer and on induction of apoptosis of tumour cells. The tumour cell line LDLX43 was used to induce breast cancer in Wistar rats. Group I (10 rats) was the control. Group II (12 rats) received repeated intratumoural in
