We present the concept of the Carbon Cycle Data Assimilation System and describe its evolution over the last two decades from an assimilation system around a simple diagnostic model of the terrestrial biosphere to a system for the calibration and initialization of the land component of a comprehensive Earth system model. We critically review the capability of this modeling framework to integrate m
Objective: Patients' own experiences of subjective symptoms are scarcely covered, and the objective of this study was to investigate the extent and characteristics of self-reported pain in patients with systemic lupus erythematosus (SLE). Methods: This study comprised a cross-sectional design where 84 patients with SLE were asked to complete self-assessments: visual analogue scale of pain and the
The clitoris contributes to the normal female sexual response cycle. A significance of cyclic guanosine monophosphate (GMP) has been assumed in the control of clitoral vascular smooth muscle. As only a few investigations on the physiology of the vascular and non-vascular clitoral tissue have been carried out, knowledge on the mechanisms controlling this particular female genital organ is still vag
The European Spallation Source (ESS) is a neutron-scattering facility being built with extensive international collaboration in Lund, Sweden. The ESS accelerator will deliver protons with 5 MW of power to the target at 2.0 GeV, with a nominal current of 62.5 mA. The superconducting part of the accelerator is about 300 meters long and contains 43 cryomodules. The ESS accelerator cryoplant (ACCP) wi
A measurement of the B-s(0) -> J/psi phi decay parameters, updated to include flavor tagging is reported using 4.9 fb(-1) of integrated luminosity collected by the ATLAS detector from root s = 7 TeV pp collisions recorded in 2011 at the LHC. The values measured for the physical parameters are phi(s) = 0.12 +/- 0.25(stat) +/- 0.05(syst) rad Delta Gamma(s) = 0.053 +/- 0.021(stat) +/- 0.010(syst) ps(
A fundamental assumption of theories of the ecology and evolution of inducible defences is that protective responses to attacks by parasites or predators should not only have benefits, but also costs. The vertebrate immune system is by far the best studied example of an inducible defence, yet little is known about the costs of an immune response, especially in natural populations. To test: if an i
Background: Free and total human kallikrein 2 (hK2) might improve the discrimination between prostate cancer and benign prostatic hyperplasia. Concentrations of hK2 are 100-fold lower than concentrations of prostate-specific antigen (PSA); therefore, an hK2 assay must have a low detection limit and good specificity. Methods: PSA- and hK2-specific monoclonal antibodies were used in solid-phase, two
The accurate quantitative analysis of high resolution ultraviolet spectra of ultra-sharp-lined early-type, chemically peculiar stars, obtained with the Goddard High Resolution spectrograph on the Hubble Space Telescope, has been made possible by the synergism between state-of-the-art astro-physics and state-of-the-art atomic spectroscopy. We illustrate this with several examples, including the dis
Systemic lupus erythematosus (SLE) is a complex systemic autoimmune disease caused by both genetic and environmental factors. Genome scans in families with SLE point to multiple potential chromosomal regions that harbor SLE susceptibility genes, and association studies in different populations have suggested several susceptibility alleles for SLE. Increased production of type I interferon (IFN) an
The use of antibiotic prophylaxis is an accepted and widely practiced feature of modern surgery. The prevention and control of infection is a priority in healthcare worldwide, and the emergence of antibiotic resistance is a global phenomenon. Hence, rational use of antibiotics is essential. We discuss the guidelines published with regard to endourologic procedures and review the limited evidence c
The structures of films of SP-B and mixtures of SP-B and DPPC at the air/water interface have been studied by neutron reflectometry (NR) and Langmuir film balance methods. From the film balance studies we observe that at very high pressures the isotherms of pure DPPC and SP-B/DPPC mixtures very nearly overlay one another, suggesting that the SP-B is being excluded from the film. The use of multipl
In Hungary an unusually high rate of parasitism on the great reed warbler Acrocephalus arundinaceus by the common cuckoo Cuculus canorus has been maintained for at least the last one hundred years. We evaluated parasitism rate, antiparasite defence and genetic differentiation among Hungarian great reed warblers at three sites located 40-130 km from each other, where hosts suffered from a high (41-
Here we unravel the structural features of human IgM and IgA that govern their interaction with the human Fc alpha/mu receptor (hFc alpha/mu R). Ligand polymerization status was crucial for the interaction, because hFc alpha/mu R binding did not occur with monomeric Ab of either class. hFc alpha/mu R bound IgM with an affinity in the nanomolar range, whereas the affinity for dimeric IgA (dIgA) was
Purpose: To evaluate long-term patency and clinical efficacy of subintimal angioplasty (SAP) of occluded infrainguinal arteries 3 years post procedure. Methods: One hundred eighty-one patients (92 men; median age 79 years) underwent attempted SAP in 193 limbs with occluded infrainguinal arteries during the period 1999 to 2001. Nearly half (83, 46%) of the patients had diabetes. Most (172, 95%) had
We discuss four variants of the graph colouring problem, and present algorithms for solving them. The problems are k-COLOURABILITY, MAX IND k-COL, MAX VAL k-COL, and, finally, MAX k-COL, which is the unweighted case of the MAX k-CUT problem. The algorithms are based on the idea of partitioning the domain of the problems into disjoint subsets, and then considering all possible instances were the va
