We develop theoretical and computational tools which can appraise traffic flow models and optimize their performance against current time-series traffic data and prevailing conditions. The proposed methodology perturbs the parameter space and undertakes path-wise analysis of the resulting time series. Most importantly the approach is valid even under non-equilibrium conditions and is based on p
Chromosomal rearrangements resulting in the fusion of coding parts from two genes or in the exchange of regulatory sequences are present in approximately 20% of all human neoplasms. More than 1000 such gene fusions have now been described, with close to 100 of them in soft tissue tumours. Although little is still known about the functional outcome of many of these gene fusions, it is well establis
Objectives: Microparticles (MP) are small membrane vesicles, released from activated, damaged and apoptotic endothelial cells (EMP) or platelets (PMP) that may actively modulate inflammation, coagulation and vascular function. We tested the hypothesis that the number of circulating EMP or PMP in acute myocardial infarction correlates with the myocardium at risk (MaR) and infarct size (IS). Methods
In lung adenocarcinoma, EGFR and KRAS mutations dominate the mutational spectrum and have clear therapeutic implications. We sought to determine whether transcriptional subgroups of clinical relevance exist within EGFR-mutated, KRAS-mutated, or EGFR and KRAS-wild type (EGFRwt/KRASwt) adenocarcinomas.
The antiphospholipid syndrome is defined by the presence of antiphospholipid antibodies in blood of patients with thrombosis or fetal loss. There is ample evidence that beta(2)-glycoprotein I (beta(2)GPI) is the major antigen for antiphospholipid antibodies. The autoantibodies recognize beta(2)GPI when bound to anionic surfaces and not in solution. We showed that beta(2)GPI can exist in at least 2
Reasoning research suggests that people use more stringent criteria when they evaluate others' arguments than when they produce arguments themselves. To demonstrate this "selective laziness," we used a choice blindness manipulation. In two experiments, participants had to produce a series of arguments in response to reasoning problems, and they were then asked to evaluate other people's arguments
We report the fabrication of three-dimensional living-cell microarrays via pin-printing of soft sol-gel-derived silica materials containing bacterial cells. Bacterial cells entrapped in the silica-glycerol microarray spots can express reporter genes and produce strong fluorescence signals. The signals responded to the presence and concentration of inducers or repressors as expected, indicating tha

A new curriculum is planned for the medical school at Lund University, Sweden. Pharmacology, in a broad sense, has been identified as a subject that needs to be strengthened based on needs in the healthcare system. The aim was to identify the competencies in basic and clinical pharmacology that a newly qualified physician needs. Using a modified three-round Delphi technique, 31 physicians were inv
We provide evidence for spontaneous quadramodal magnetic orientation in a larval insect. Second instar Berlin, Canton-S and Oregon-R x Canton-S strains of Drosophila melanogaster exhibited quadramodal orientation with clusters of bearings along the four anti-cardinal compass directions (i.e. 45, 135, 225 and 315 deg). In double-blind experiments, Canton-S Drosophila larvae also exhibited quadramod
Introduction: Complement activation is involved in rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and atypical hemolytic uremic syndrome (aHUS). Autoantibodies to complement inhibitor factor H (FH), particularly in association with deletions of the gene coding for FH-related protein 1 (CFHR1), are associated with aHUS. Methods: Autoantibodies against FH, factor I (FI) and C4b-bindin
The spatial strain distribution in and around a single axial InAs1-xPx hetero-segment in an InAs nanowire was analyzed using nano-focused X-ray diffraction. In connection with finite-element-method simulations a detailed quantitative picture of the nanowire's inhomogeneous strain state was achieved. This allows for a detailed understanding of how the variation of the nanowire's and hetero-segment'
In this article, using orbits of the dynamical system generated by the function F, operator representations of commutation relations XX* = F (X* X) and AB = BF (A) are studied and used to investigate commuting operators expressed using polynomials in A and B. Various conditions on the function F, defining the commutation relations, are derived for monomials and polynomials in operators A and B to
Background: Head trauma may present as transient loss of consciousness (TLOC) currently classified as traumatic in origin, in contrast to non-traumatic forms, such as syncope. Whether past history of syncope predisposes to loss of consciousness after head injury has been poorly studied. Methods: A retrospective analysis of data obtained from 818 consecutive patients admitted to Emergency Departmen
Manufacturing firms aim at improving both internal and external processes to improve the competitive advantage. Such initiatives include lean practices as well as supplier rationalization and integration. In this paper, we analyze these improvement initiatives and their impact on business performance. In particular, we explore potential differences between make-to-order (MTO) and make-to-stock (MT
Objective. To describe the suicidal career in the long-term course of severe depression. Subjects and Method. Seventy-five former in-patients were interviewed by telephone about course of depression and suicide attempts 37-53 years after index admission. Medical records were read in many cases. Results. 29 subjects had attempted suicide, 13 repeated, 10 made severe, and 13 violent attempts. The ri
Intracellular free heme predisposes to oxidant-mediated tissue damage. We hypothesized that free heme causes alterations in myocardial contractility via disturbed structure and/or regulation of the contractile proteins. Isometric force production and its Ca(2+)-sensitivity (pCa50) were monitored in permeabilized human ventricular cardiomyocytes. Heme exposure altered cardiomyocyte morphology and e
Let R denote a connected region inside a simple polygon, P. By building 1-dimensional barriers in P ∖ R, we want to separate from Rpart(s) of P of maximum area. In this paper we introduce two versions of this problem. In the budget fence version the region R is static, and there is an upper bound on the total length of barriers we may build. In the basic geometric firefighter version we assume tha
We study the problem of efficiently correcting an erroneous product of two n x n matrices over a ring. We provide a randomized algorithm for correcting a matrix product with k erroneous entries running in (O) over tilde(root kn(2)) time and a deterministic (O) over tilde (kn(2))-time algorithm for this problem (where the notation (O) over tilde suppresses polylogarithmic terms in n and k).
