A measurement of the cross-section for ϒ ( 1 S ) → μ + μ − production in proton–proton collisions at centre of mass energy of 7 TeV is presented. The cross-section is measured as a function of the ϒ ( 1 S ) transverse momentum in two bins of rapidity, | y ϒ ( 1 S ) | < 1.2 and 1.2 < | y ϒ ( 1 S ) | < 2.4 . The measurement requires that both muons have transverse momentum p T μ > 4 GeV and pseudora

Reduced membranous expression of the cytoskeleton-associated protein ezrin has previously been demonstrated to correlate with tumour progression and poor prognosis in patients with T1G3 urothelial cell carcinoma of the bladder treated with non-maintenance Bacillus Calmette-Guérin (n = 92), and the associations with adverse clinicopathological factors have been validated in another, unselected, coh

Strandberg R., Hake M., Klaassen R.H.G. & Alerstam T. 2012. Movements of immature European Honey Buzzards Pernis apivorus in tropical Africa. Ardea 100: 157-162. Immature European Honey Buzzards Pernis apivorus are believed to remain in tropical Africa during the first years of their lives. We studied their movements during this period with the aid of satellite telemetry. After crossing the Sa

A reporter system was constructed to measure perturbations in the NADH/NAD(+) co-factor balance in yeast, by using the green fluorescent protein gene under the control of the GPD2 promoter that is induced under conditions of excess of NADH. High fluorescence levels were obtained in a glycerol 3-phosphate dehydrogenase double deletion strain (gpd1Δgpd2Δ), which is deficient in the ability to regene

The natural history of oncogenic human papillomavirus (HPV) infections results from interactions of the virus, the host, and multiple cofactors. We studied the association between humoral immune response to HPV and smoking in 191 HPV infected women prospectively. Two follow-up samples (first and last) were analysed for serum cotinine levels, IgA and IgG antibodies to HPV16 and 18, and Chlamydia tr

The association between exposure to perfluorinated compounds (PFCs) and attention deficit hyperactivity disorder (ADHD) diagnosis has been sparsely investigated in humans and the findings are inconsistent.

Objective: Lewy-related pathology is the characteristic feature of Parkinson's disease with and without dementia and dementia with Lewy bodies (DLB). There are two neuropathological staging systems for Lewy-related pathology commonly employed today: the staging system for Parkinson-related pathology by Braak et al., and the staging system by the Consortium on DLB. There are also several modified s

Popular Abstract in Swedish Ekonomin och välfärden är starkt beroende av tillförlitlig transport och energiförsörjningsteknologi. En stor del av denna teknik bygger på användandet av förbränningsmotorer. Då dessa till antalet är så stort utgör de tillsammans en stor miljöbelastning. Därför måste det läggas stora resurser på förbättrad motorstyrning och avgasrening. En av restprodukterna från förBoth the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. Because of the large numbers of internal combustion engines in use around the world, their emissions have a significant environmental impact. Therefore, considerable efforts have been i

Quantum chemical calculations provide detailed theoretical information concerning key aspects of photoinduced electron and excitation transfer processes in supramolecular donor-acceptor systems, which are particularly relevant to fundamental charge separation in emerging molecular approaches for solar energy conversion. Here we use density functional theory (DFT) calculations to explore the excite

An interesting feature of dung beetle behaviour is that once they have formed a piece of dung into a ball, they roll it along a straight path away from the dung pile. This straight-line orientation ensures that the beetles depart along the most direct route, guaranteeing that they will not return to the intense competition (from other beetles) that occurs near the dung pile. Before rolling a new b

Single cell gene expression assays have become a powerful tool with which to dissect heterogeneous populations. While methods and software exist to interrogate such data, what has been lacking is a unified solution combining analysis and visualisation which is also accessible and intuitive for use by non-bioinformaticians, as well as bioinformaticians.

We consider simple approximations of variances and covariances for order statistics from the standard extreme value distribution. Exact values and simulation results of the variances and covariances for certain sample sizes are used to determine the validity of the suggested approximations.

Objective. There is an increased risk of gastrointestinal carcinoma and smoking-related diseases after partial gastrectomy for peptic ulcer disease. The purpose of this study was to evaluate long-term cancer incidence and mortality after parietal cell vagotomy (PCV), a surgical method with a low rate of side effects, but creating hypochlorhydria in the stomach mimicking long-term treatment with an

Kaposi sarcoma (KS) is a locally aggressive endothelial tumour that is classified into 4 clinico-epidemiological forms: classic KS affecting lower limbs in elderly Mediterranean or East European men; endemic KS occurring in extremities among Equatorial African middle-aged men and children; iatrogenic KS involving lower limbs in immunosuppressive patients; and AIDS-associated (epidemic) KS observed

The performance of a millimetre-wave wavelet generator under picosecond-pulsed trigger operation conditions has been evaluated experimentally. The reactively-loaded resonant tunnelling diodes metal-oxide-semiconductor field-effect-transistor circuit is shown to generate well-formed wavelets for control pulse-lengths down to approximately the free-running carrier oscillation period. Transient circu

Non-Gaussian stochastic fields are introduced by means of integrals with respect to independently scattered stochastic measures distributed according to generalized Laplace laws. In particular, we discuss stationary second order random fields that, as opposed to their Gaussian counterpart, have a possibility of accounting for asymmetry and heavier tails. Additionally to this greater flexibility th
