This paper presents a low band antenna impedance tuner in 130nm CMOS-SOI technology. It consists of three digitally controlled switched capacitor banks and two off-chip inductors and is intended for use in terminals supporting modern cellular standards like WCDMA and LTE. By using a negative gate bias in the off state, linearity can be improved and maintained. Measurements show an OIP3 exceeding +
The dynamics and consequences of host-parasite coevolution depend on the nature of host genotype-by-parasite genotype interactions (G × G) for host and parasite fitness. G × G with crossing reaction norms can yield cyclic dynamics of allele frequencies ("Red Queen" dynamics) while G × G where the variance among host genotypes differs between parasite genotypes results in selective sweeps ("arms ra
Background: Residential wood combustion is now recognized as a major particle source in many developed countries, and the number of studies investigating the negative health effects associated with wood smoke exposure is currently increasing. The combustion appliances in use today provide highly variable combustion conditions resulting in large variations in the physicochemical characteristics of
Background: There is an opportunity to improve the image quality and lesion detectability in single photon emission computed tomography (SPECT) by choosing an appropriate reconstruction method and optimal parameters for the reconstruction. Purpose: To optimize the use of the Flash 3D reconstruction algorithm in terms of equivalent iteration (EI) number (number of subsets times the number of itera
The chapter is a discussion of the limitations and possibilities of digital film archives with reference to the specific needs of experimental film culture. Some films by filmmakers Reinhold Holtermann and Hans Nordenström are discussed in the framwork of the Swedish digital film archive "filmarkivet.se".
Popular Abstract in Swedish Den mänskliga arvsmassan består bara till en begränsad del av gener som kodar för proteiner som används för livsnödvändiga funktioner. Så mycket som 50 % eller mer består av repetitiva sekvenser, dvs sådana DNA element som finns i 100-100.000-tals mer eller mindre identiska kopior. Man kan säga att dessa är genetiska parasiter som använder sig av den mänskliga cellens eHuman endogenous retroviruses (HERVs) are remains of ancient retroviral infections of the germ line and constitute as much as 3 % of the human genome. HERVs are genetic elements that potentially may provide important biological functions by several different mechanisms. The ability to transpose long after the initial insertion into the germ line may provide a potent source of insertional mutagenes
Phosphonated polymers may show high intrinsic proton conductivities at low water contents provided that the local concentration of phosphonic acid groups is very high [1,2]. Moreover, the lower acidity of aryl- and alkylphosphonic acids in relation to sulfonic acids requires higher acid contents to reach high conductivities also at higher water contents. In this context, poly(vinylphosphonic acid)
This report is part of the National evaluation of the Swedish compulsory school. The evaluation was conducted by the National Board of Education in 2003. The present report deals with pupils' attitudes to History as a subject and to history education in the 9th grade. We have also made an evaluation of pupils' knowledge of history. The survey shows that a majority of the pupils have positive views
In Förgängligheter (Transiences), eight scholars and authors present new perspectives on transience in our time. The authors belong to different fields, such as film studies, comparative literature, musicology, visual studies, intermediality studies, ethnology and history. Among the topics in the book, you find the TV-series "Six Feet Under", Bob dylan's lyrics, modern art history, flowers, buildi
The aim of this work is to provide a survey of interesting open problems in the theory of Bergman spaces
