Transforming growth factor-§ (TGF-§) is a potent, multifunctional growth factor affecting virtually all cell types, regulating critical physiological processes like immune response, wound healing, angiogenesis, and tumor development. A large number of studies in vitro have also implicated a critical role of TGF-§ in regulating hematopoiesis by inhibiting proliferation of hematopoietic stem cells (

The main idea of this paper is to use distances between camera positions to recover the trajectory of a mobile robot. We consider a mobile platform equipped with a single fixed camera using images of the floor and their associated inter-image homographies to find these distances. We show that under the assumptions that the camera is rigidly mounted with a constant tilt and travelling at a constant

Internmedicin är en heltäckande lärobok i ämnet och beskriver organrelaterade sjukdomar, allergier, förgiftningar och drogskador. Boken innehåller även ett kapitel i symtomlära. Sjukdomarna beskrivs grundligt med uppgifter om bland annat symtom, förekomst, etiologi, anamnes och utredning samt handläggning

Under de senaste decennierna har förutsättningarna för att välja utbildning förändrats drastiskt. Eleverna står inför en lång rad valmöjligheter gällande inriktning, huvudman och skola. Detta ställer nya krav på grundskolan, som förväntas förbereda elever för att göra genomtänkta val. Emellertid tycks inte grundskolans faktiska hantering av dessa frågor ha utvecklats i nämnvärd mening. Tidigare ra

This chapter will look at why, how and in what way a spontaneous memorial may develop: from an immediate act to a more planned place of grief and remembrance (Clark and Franzmann 2006, Nieminen Kristofersson 2006, Klaasens, Groote and Huigen 2009). Of special importance for this investigation are the noticeable differences in attitudes to and growths of roadside memorials revealed by data gleaned

Popular Abstract in Swedish I människokroppen finns tre typer av muskulatur, skelettmuskel, hjärtmuskel och glatt muskulatur. Skelettmuskulatur kan styras med tanken, och vi kan använda den när vi t.ex. skall lyfta tekoppen på morgonen. Hjärtmuskel finns i hjärtat och slår oavbrutet så länge vi lever. Glatt muskulatur är ej viljestyrd och finns i de flesta inre organ, t.ex. blodkärlens väggar, lufIn man, the urinary bladder responds to an urinary outflow obstruction with a pronounced dilatation and growth of the bladder wall. This clinical situation can be mimicked in rat by creation of a partial urinary outflow obstruction and the papers included in the present thesis use this animal model to address questions regarding the adaptive changes in the smooth muscle of the growing bladder. In

This paper presents a study with the intent to examine the opportunities provided by creating and using simulation models of software development processes. A model of one software development project was created through means of system dynamics, with data collected from documents, interviews and observations. The model was simulated in a commercial simulation tool. The simulation runs indicate th

The chapter gives an overall picture of the conditions of labour market entry for young people (16-19 years) and young adults (20-24 years) and their social exclusion in Sweden from the early 1990s until now. The chapter consists of three sections. The first section provides background information on the entry of young people on the Swedish labour market. The overview summarizes research findings

The focus of the thesis is on chemically cross-linked hydrogels which drastically change their volume when immersed in solutions of different ionic surfactants (with or without added salt). The two main questions addressed are: (1) How useful are simple gel swelling experiments to the study of polymer-surfactant interactions?, and (2) How does the volume of a cross-linked polymer gel change when i

The design of a digital baseband for a low power wireless receiver in 65 nm CMOS is presented. It consists of decimation filtering, matched filters for data detection, and preamble based synchronization. The circuit was designed using low threshold devices in both low power (LP-LVT) and general-purpose (GP-LVT) domains. The fabricated circuits were functionally verified, and silicon measurements s

Exempel från 1600-talet på förändringar av mi'kmaqs traditioner visar att mötet med den europeiska kulturen inte var konfliktfritt och mötte motstånd från mi'kmaq. Beskrivningarna om missionens snabba framgång ger inte en helt rättvisande bild. Det var missionärerna som skrev historien och de ville också framstå i en fördelaktig dager inför sina överordnade. För de mi'kmaq som samlades kring missi

This compilation should be viewed as a kind of prolegomena to a history of interpolation. Three letters from Mischa Cotlar, Antoni Zygmund and Olof Thorin from c. 1980 are reproduced. Thorin's letter is given in translation. These letters were written as a reply to an inquiry by the editor/translator. It is remarkable that while Thorin spent his whole professional life as an actuary, neither of hi

Popular Abstract in Swedish I atmosfären finns förutom olika gaser, såsom kväve, syre, vattenånga och en mängd gaser i låga koncentrationer, även partiklar. Dessa partiklar kallas aerosolpartiklar och de kan hålla sig svävande upp till flera veckor innan de deponeras till marken igen. Moln- och dimmdroppar bildas i atmosfären genom att vattenånga kondenserar på aerosolpartiklar. Detta kan ske då lIn this work, cloud and fog droplet formation was studied in three joint field experiments. The instrument, the droplet aerosol analyser (DAA), has also been further developed and verified as part of this work. The DAA is an instrument especially developed for studies of cloud and fog droplet formation and growth. It measures the ambient size of individual droplets and interstitial particles in a

In this paper we investigate partial response signaling (PRS) systems that are intended to operate close to capacity. We show that finding PRS systems with maximal capacity is a rather easy optimization task. We give an alternate way of defining bandwidth for PRS systems based on capacity considerations; this differs considerably from the traditional method based on transmission power. Practical P
