We extend our earlier work on the massive O(N) non-linear sigma model to other observables. We derive expressions at leading order in the large N expansion at all orders in the loop expansion for the decay constant, vacuum expectation value, meson meson scattering and the scalar and vector form factors. This is done using cactus diagram resummation using a generalized gap equation and other recurs

Electromagnetic interactions between colliding heavy ions at the Large Hadron Collider (LHC) at CERN will give rise to localized beam losses that may quench superconducting magnets, apart from contributing significantly to the luminosity decay. To quantify their impact on the operation of the collider, we have used a three-step simulation approach, which consists of optical tracking, a Monte Carlo

An account is given of the general morphology, reproductive biology, ecology and historical exploration of the green alga order Oedogoniales. About 150 species belonging to the genera Oedogonium and Bulbochaete have been recorded from Sweden during the period 1864–1964. Notably, more than 80 taxa were described as new for science based on material from Swedish sites by the Scandinavian algologists

Many extensions of the Standard Model predict the existence of charged heavy long-lived particles, such as R-hadrons or charginos. These particles, if produced at the Large Hadron Collider, should bemoving non-relativistically and are therefore identifiable through the measurement of an anomalously large specific energy loss in the ATLAS pixel detector. Measuring heavy long-lived particles through

INTRODUCTION: Sex steroids are important for growth and maintenance of the skeleton. Catechol-O-methyltransferase (COMT) is an estrogen degrading enzyme. The COMT val158met polymorphism results in a 60-75% difference in enzyme activity between the val (high activity=H) and met (low activity=L) variants. We have previously reported that this polymorphism is associated with bone mineral density (BMD

Allvarliga fuktproblem i ytterväggar med regelstomme av trä och fasadskikt av puts på isolering har under senare delen av 2000-talet konstaterats i Sverige. Ett alternativ byggsätt för den putsade fasaden är att putsa mot ett skivunderlag som sitter monterat mot läkt så att en luftspalt bildas. Om spalten i över- och underkant kan kommunicera med utomhusluften så kommer vind och temperaturskillnad

We study multiple electron transfer from a CdSe quantum dot (QD) to ZnO, which is a prerequisite for successful utilization of multiple exciton generation for photovoltaics. By using ultrafast time-resolved spectroscopy we observe competition between electron injection into ZnO and quenching of multiexcitons via Auger recombination. We show that fast electron injection dominates over biexcitonic A

A recent report of the EuroHeart project has shown that women are still underrepresented in many cardiovascular clinical trials, while important gender differences are present within most areas of heart disease. As the burden of cardiovascular disease is increasing in middle-aged women relative to men, a more profound understanding is needed of the fundamental biological differences that exist bet

This study examined mortality and predictors of death in 1,396 primary amphetamine users (85% males) who were interviewed with the Addiction Severity Index in the Swedish criminal justice system during 2000-2006 and followed through 2008. Forty-nine clients deceased (standardized mortality ratio 4.1 [3.0-5.4]), at least 84% of deaths were violent or drug-related (12% suicides), and Cox regression

Coulomb-excitation experiments are performed with postaccelerated beams of neutron-deficient Po-196,Po-198,Po-200,Po-202 isotopes at the REX-ISOLDE facility. A set of matrix elements, coupling the low-lying states in these isotopes, is extracted. In the two heaviest isotopes, Po-196,Po-198, the transitional and diagonal matrix elements of the 2(1)(+) state are determined. In Po-196,Po-198 multiste

The article discusses the impact of comparative/historical philology upon the question of nuclear semiotics, i.e. the field of how humanity is to communicate information about nuclear waste storage into the distant future and its (presumably human) inhabitants. It also turns this perspective on its head and discusses possible insights in the other direction – what Nuclear Semiotics can teach histo

Objective. To analyse the management of muscle-invasive bladder cancer in a population-based national register, and specifically to investigate the role of curative therapy (i.e. cystectomy or radiotherapy) in relation to patient, tumour and hospital characteristics. Material and methods. The Swedish Bladder Cancer Register covers more than 90% of all patients in the country who have been diagnose

Selective immunoglobulin A deficiency (IgAD) is the most common primary immunodeficiency in Caucasians. It has previously been suggested to be associated with a variety of concomitant autoimmune diseases. In this review, we present data on the prevalence of IgAD in patients with Graves disease (GD), systemic lupus erythematosus (SLE), type 1 diabetes (T1D). celiac disease (CD), myasthenia gravis (

Several studies have proposed aerobic methane (CH4) emissions by plants. If confirmed, these findings would further increase the imbalance in the global CH4 budget which today underestimates CH4 sinks. Oxidation by OH-radicals in the troposphere is the major identified sink followed by smaller contribution from stratospheric loss and oxidation by methano- and methylotrophic bacteria in soils. This
