Oral direct thrombin inhibitor AZD0837 for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation: a randomized dose-guiding, safety, and tolerability study of four doses of AZD0837 vs. vitamin K antagonists

Aims Oral anticoagulation with vitamin K antagonists (VKAs) for stroke prevention in atrial fibrillation (AF) is effective but has significant limitations. AZD0837, a new oral anticoagulant, is a prodrug converted to a selective and reversible direct thrombin inhibitor (AR-H067637). We report from a Phase II randomized, dose-guiding study (NCT00684307) to assess safety, tolerability, pharmacokinet

Malignancy as a comorbidity in rheumatic diseases.

Patients with systemic autoimmune rheumatic diseases, particularly RA, SLE, SS and idiopathic inflammatory myopathies, are at increased risk of developing malignancies. Cancer occurrence adds to the disease burden in these patients, adversely affecting quality of life and life expectancy. This risk is related to the pathobiology of the underlying rheumatic disease including the inflammatory burden

Reducing the Cycle-Cycle Variability of a Natural Gas Engine Using Controlled Ignition Current

Running an internal combustion engine with diluted methane/air mixtures has a potential of reducing emissions and increasing efficiency. However, diluted mixtures need high ignition energy in a sufficiently large volume, which is difficult to accomplish. Increasing the spark duration has shown to be a promising way of delivering more energy into the diluted charge, but this requires a more sophist

A method for identification of geometrical tool changes during machining of titanium alloy Ti6Al4V

There exists an increasing demand for cost and time efficient cutting tests for describing the performance of different combinations of cutting tools and workpiece materials in the cutting process both in industry and academia. Cutting tools are expected to withstand the heat and the pressure developed during the machining of difficult to machine materials such as Ti6Al4V. This article introduces

Search for extra dimensions using diphoton events in 7 TeV proton-proton collisions with the ATLAS detector ATLAS Collaboration

Using data recorded in 2011 with the ATLAS detector at the Large Hadron Collider, a search for evidence of extra spatial dimensions has been performed through an analysis of the diphoton final state. The analysis uses data corresponding to an integrated luminosity of 2.12 fb(-1) of root s = 7 TeV proton-proton collisions. The diphoton invariant mass (m(gamma gamma)) spectrum is observed to be in g

The Moral Status of Extraterrestrial Life

Abstract If we eventually discover extraterrestrial life, do we have any moral obligations for how to treat the life-forms we find; does it matter whether they are intelligent, sentient, or just microbial-and does it matter that they are extraterrestrial? In this paper, I examine these questions by looking at two of the basic questions in moral philosophy: What does it take to be a moral object? a

Scaling of the mean and variance of population dynamics under fluctuating regimes

Theoretical ecologists have long sought to understand how the persistence of populations depends on the interactions between exogenous (biotic and abiotic) and endogenous (e.g., demographic and genetic) drivers of population dynamics. Recent work focuses on the autocorrelation structure of environmental perturbations and its effects on the persistence of populations. Accurate estimation of extinct

Leadership On Demand: Followers as initiators and inhibitors of managerial leadership

A key aspect of leadership is the followers’ constructions of its value and relevance. Based on two empirical, qualitative case studies, this paper highlights the importance of the ‘demand’ for leadership when leader–follower relationships are established. We further discuss how followers influence, inhibit and initiate managerial leadership (i.e. leadership acts from their formal superior targeti

Diagnosis and progression of sacroiliitis in repeated sacroiliac joint computed tomography.

Objective. To assess the clinical utility of repeat sacroiliac joint computed tomography (CT) in sacroiliitis by assessing the proportion of patients changing from normal to pathologic at CT and to which degree there is progression of established sacroiliitis at repeat CT. Methods. In a retrospective analysis of 334 patients (median age 34 years) with symptoms suggestive of inflammatory back pain,

A new model for CO₂-absorption of concrete structures. CO₂-cycle in cement and concrete Part 7: Models for CO₂-absorption.

After further laboratory and field studies we have now used the previous and new findings to create a model for CO₂-absorption of concrete structures. Some knowledge is still missing and some results are still not fully understood. In those cases we have done our best to base the model on reasonable assumptions, from what could be expected from some new literature that has been studied.

New aristonectine elasmosaurid plesiosaur specimens from the Early Maastrichtian of Angola and comments on paedomorphism in plesiosaurs

New elasmosaurid plesiosaur specimens are described from the Early Maastrichtian of Angola. Phylogenetic analyses reconstruct the Angolan taxon as an aristonectine elasmosaurid and the sister taxon of an unnamed form of similar age from New Zealand. Comparisons also indicate a close relationship with an unnamed form previously described from Patagonia. All of these specimens exhibit an ostensibly

Inverse Problems for Graph Laplacians

This thesis is devoted to inverse spectral problems for Laplace operators on metric graphs, and it is based on the following papers: Paper I - P. Kurasov and M. Nowaczyk 2005 Inverse spectral problem for quantum graphs J. Phys. A: Math. Gen 38 4901--15 Paper II - M. Nowaczyk 2007 Inverse spectral problem for quantum graphs with rationally dependent edges Operator Theory, Analysis and Mathematical

COMP a candidate molecule in the pathogenesis of systemic sclerosis with a potential as a disease marker

OBJECTIVE: COMP primarily found in cartilage is thought to be an important regulator of assembly and maintenance of the fibrillar collagen I and II networks. Recently COMP was shown to be produced by skin fibroblasts from patients with systemic sclerosis (SSc, scleroderma). The purpose of this study was to examine whether COMP is released from skin to serum in SSc patients, and may serve as indica

Model-Based Detection of Heart Rate Turbulence Using Mean Shape Information

A generalized likelihood ratio test (GLRT) statistic is proposed for detection of heart rate turbulence (HRT), where a set of Karhunen-Loeve basis functions models HRT. The detector structure is based on the extended integral pulse frequency modulation model that accounts for the presence of ectopic beats and HRT. This new test statistic takes a priori information regarding HRT shape into account,
