The problem of fundamental frequency estimation is considered in the context of signals where the frequencies of the harmonics are not exact integer multiples of a fundamental frequency. This frequently occurs in audio signals produced by, for example, stiff-stringed musical instruments, and is sometimes referred to as inharmonicity. We derive a novel robust method based on the subspace orthogonal
The results of a search for pair production of light top squarks are presented, using 4.7 fb(-1) of root s = 7 TeV proton-proton collisions collected with the ATLAS detector at the Large Hadron Collider. This search targets top squarks with masses similar to, or lighter than, the top quark mass. Final states containing exclusively one or two leptons (e, mu), large missing transverse momentum, ligh
Popular Abstract in Swedish Sepsis, blodförgiftning är en systemisk inflammatorisk reaktion syndrom vid en lokal eller systemisk infektion som leder till överproduktion av proinflammatoriska cytokiner och det ultimata misslyckandet av flera organsystem. Sepsis är ett potentiellt allvarligt och komplicerat kliniskt syndrom samt är en av de vanligaste orsakerna till döden på intensivvårdsavdelningarSepsis is a systemic inflammatory response syndrome to a localized or systemic infection that leads to the over production of proinflammatory cytokines and the ultimate failure of multiple organ systems. However, little is known about the potential role of Rac1 in controlling sepsis-induced intracellular signaling pathways. We hypothesized that Rac1 might be involved in sepsis mediated signaling p
In this work the structure of ternary GaxIn1-xP nanowires is investigated with respect to the chemical composition and homogeneity. The nanowires were grown by metal-organic vapor-phase epitaxy. For the investigation of ensemble fluctuations on several lateral length scales, X-ray diffraction reciprocal space maps have been analyzed. The data reveal a complicated varying materials composition acro
Denna studie behandlar fuktförhållandena i regnexponerade träkonstruktioner, d.v.s. träkonstruktioner som når höga fuktkvoter. Särskilt fokus var på mikroklimatet (klimatet på träets yta) och materialklimatet (träets fuktkvot) i anslutningar. Metoder för att mäta mikroklimatet, d.v.s. våttider på en träyta och varaktighet av vatten i spalter, utvecklades liksom en metod för att mäta fuktkvot nära This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. Methods for determination of microclimate, i.e. the duration of moisture on a wooden surface and the duration of water trapped in gaps between two
We report a measurement of the cross section of single top-quark production in the t-channel using 1.04 fb(-1) of pp collision data at root s = 7 TeV recorded with the ATLAS detector at the LHC. Selected events feature one electron or muon, missing transverse momentum, and two or three jets, exactly one of them identified as originating from a b quark. The cross section is measured by fitting the
In this paper a controller reduction method for discrete-time linear time-invariant systems is described. Using the bounded-real lemma, the proposed method generates reduced controllers with closed loop stability and H-infinity norm performance guarantee. Information of the full controller is used as a basis for reduction using singular value decomposition. This is different from traditional model
This licentiate thesis investigates fiction writing and reading in up- per secondary school in Sweden. Inspired by fanfiction I created a teaching project of derivative writing in which the students in a se- cond-year social science class wrote short stories derived from 20th century novels. They also gave peer response, both orally and in writing. Finally they wrote a reflective text about the pr
Breath alcohol analysis constitutes sufficient material for the prosecution of drunk driving without the need for blood analysis. However, the prevailing method used for breath analysis lacks standardization of several physiological variables that cause a variation of the breath alcohol concentration (BrAC). In this thesis, a novel analyzer which standardizes the BrAC to the water vapour concentra
Assessment of health-related quality of life (HRQoL) in haemophilia is important in order to provide information for clinical decision making and to verify the impact of haemophilia on patients and their families. Advances in haemophilia care and prophylactic treatment have improved HRQoL for the patients and where treatment is available, patients with haemophilia have almost reached the same life
An internal tandem duplication of FLT3 (FLT3/ITD) occurs in approximately 25% of newly diagnosed AML. PKC412 inhibits the growth of leukemic cell lines with FLT3 mutations such as the MV4-11. This study evaluated the in vitro effects of the combination of PKC412 and ara-C or daunorubicin, studying the effect of co-incubation, pre-incubation and sequential incubation of the drugs in patient samples
Gluconobacter oxydans whole cells and membrane fractions in combination with ferrocene mediators were used to study oxidation of ethanol. The efficiency of mediator?enzyme interaction was assessed by the ratio of maximum current to the apparent Michaelis constant (Imax/KM) for saturating mediator concentrations. The bioelectrocatalytic processes were found to be more efficient with membrane fracti
Rules on standing hold the power to enable, as well as to foreclose, intervention in regulatory processes. As such, they determine who may challenge regulatory power, and according to which criteria. This makes standing rules pivotal to any legal system. In the EU context, the Court of Justice of the European Union (CJEU) has been much criticised over the years for its narrow interpretation of dir
Background: Sexual conflict over mating rates may favour the origin and maintenance of phenotypes with contrasting reproductive strategies. The damselfly Ischnura elegans is characterised by a female colour polymorphism that consists of one androchrome and two gynochrome female morphs. Previous studies have shown that the polymorphism is genetic and to a high extent maintained by negative frequenc
