Many of the interesting physics processes to be measured at the LHC have a signature involving one or more isolated electrons. The electron reconstruction and identification efficiencies of the ATLAS detector at the LHC have been evaluated using proton-proton collision data collected in 2011 at TeV and corresponding to an integrated luminosity of 4.7 fb. Tag-and-probe methods using events with lep
Meteorological data and soil data have been collected at a site in the central Sudan from 2002 to 2012. The site is a sparse savanna in the semiarid region of Sudan. In addition to basic meteorological variables, soil properties (temperature, water content, and heat flux) and radiation (global radiation, net radiation, and photosynthetic active radiation) were measured. The dataset has a temporal
This paper describes a highly digitized direct conversion receiver of a single-chip quadruple-band RF transceiver that meets GSM/GPRS and EDGE requirements. The chip uses an advanced 0.25-mum BiCMOS technology. The I and Q on-chip fifth-order single-bit continuous-time sigma-delta (SigmaDelta) ADC has 84-dB dynamic range over a total bandwidth of +/-135 kHz for an active area of 0.4 mm(2). Hence,
Abstract OBJECTIVES: The aim of this study was to investigate whether psychosocial resources explain socioeconomic differences in smoking cessation and its maintenance. METHODS: A subpopulation of 11,837 individuals from the Malmö Diet and Cancer Study interviewed in 1992-94, age range 45-64 years, was investigated in this cross-sectional study. A multivariate logistic regression model was used t
Popular Abstract in Swedish Öbiogeografi och populationsdifferentiering hos Skyros murödla Hur den fantastiska variationen som finns i naturen bildas är en fråga som länge fascinerat biologer. För mer än 150 år sedan inledde två välkända biologer, Charles Darwin och Alfred Russel Wallace, en brevväxling som skulle komma att bli startskottet för ett paradigmskifte. De hade båda fått idén om naturlIslands are cradles for new biodiversity and provide natural laboratories for the study of population divergence. In my thesis, I investigated the role of different evolutionary processes in the population divergence in the Skyros wall lizard (Podarcis gaigeae), a species where islet populations have strongly diverged morphologies. I used replicate islet populations and their respective most proxi
Cyclic AMP potentiates glucose-stimulated insulin release and mediates the stimulatory effects of hormones such as glucagon-like peptide 1 (GLP-1) on pancreatic b-cells. By inhibition of cAMP-degrading phosphodiesterase (PDE) and, in particular, selective inhibition of PDE3 activity, stimulatory effects on insulin secretion have been observed. Molecular and functional information on b-cell PDE3 is
Popular Abstract in Swedish I Big Bang, då vårt Universum skapades, bildades i princip endast de två lättaste grundämnena, väte och helium. Alla andra grundämnen har skapats, och skapas fortfarande, i olika typer av stjärnor under olika utvecklingsfaser. Detta betyder att precis alla atomer, förutom väte och helium, som bygger upp alla saker, växter, djur och människor i vår omgivning, har bildatsDisregarding the small primordial traces of the lightest elements, all metals have been formed in stellar processes, which means that the relative amount of metals in the Universe increases for every stellar generation. This build-up of elements is called chemical evolution and might be used both to constrain stellar models as well as understanding the formation and evolution of stellar population
The concept “Broken Technologies” is related to the question: “Which is the benefit of humanity studies?” Of course the question is rhetorical because, how could this question be answered if the benefit was not obvious? Any answer supposes that we understand what we are asking for and the study of “what we mean” is one of the axes of the epistemology of the humanities. Anyway, we can also put the
The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. The inv
Meta Isæus-Berlin: The Animated Installations Torsten Weimarck At about the same time that I saw Meta Isæus-Berlin’s remarkable installation Ett vattenhem (A Water Home) at the Bo01 Housing Fair in Malmö I also happened to see Johannes Stjärne Nilsson and Ola Simonsson’s film Music for one appartment and six drummers which was shown as a supporting film in the cinema. It struck me that these wo
An essential problem of ‘knowledge management’ is the impossibility of codifying ‘knowledge’ which is embedded in human agents. It can never be straightforward for members of an organization to share what they know with one another. Such a process might be facilitated, but would be difficult to ‘manage’. In recognition of this, organizations have sought ways to support knowledge sharing processes,
The aim of the thesis work is the further development of practical engine simulation tools based on Stochastic Reactor Models, SRMs. Novel and efficient implementations were made of a variety of SRMs adapted to different engine types. The models in question are the HCCI-SRM, the TwoZone SI-SRM and the DI-SRM. The specific models developed were incorporated into two different interfaces: DARS-ESSA,
Popular Abstract in Swedish Avhandlingen presenterar ett närstudium av fjorton centrala pjäser skrivna av den svenske författaren Lars Norén (1944-) under perioden 1979-90. I centrum ställs frågan om den ouppklarade relationen till modern, i första hand hos de vuxna, vanligtvis redan in i medelåldern hunna barn som gestaltas i dessa pjäser. I den krisdrabbade intimsfär som Noréns huvudsakligen skiThis dissertation presents a close study of fourteen central dramas written by the Swedish author Lars Norén (1944-) between 1979 and 1990. The question at issue is the unfinished condition of the relation to the mother, mainly among the grown-up, in most cases middle-aged children portrayed in the plays. In the crisis of intimacy, Norén's major thematic motif in his dramatic works of the 1980s ("
A large-scale, high-efficiency and low-cost platform based on a Beckman Coulter Biomek FX and custom-made automation systems for structural genomics has been set up at Peking University, Beijing, People's Republic of China. This platform has the capacity to process up to 2000 genes per year for structural and functional analyses. Bacillus subtilis, a model organism for Gram-positive bacteria, and
Background/Objectives A cascade of gene activations under the control of Notch signalling is required during T-cell specification, when T-cell precursors gradually lose the potential to undertake other fates and become fully committed to the T-cell lineage.We elucidate how the gene/protein dynamics for a core transcriptional module governs this important process by computational means. Methods We
The Bluethroat subspecies Cyanecula svecica svecia occurs throughout the northern Palearctic. European C. s. svecia has been shown to follow a route west of the Himalaya to winter quarters in southern Asia. Out of 30 Bluethroats tagged with geolocators in eastern Siberia, we obtained one track suggesting that it migrated east of the Himalaya to a wintering area located in Myanmar. The different ro
The aim of this thesis is to investigate whether quantum interference between indistinguishable hadronization histories, that is, different ways the string can break while resulting in the same final state, can lead to observable effects in the momentum distributions of particles produced in string fragmentation. In the standard picture, hadronization is treated as a probabilistic process in which
