Search for gravitational waves from binary black hole inspiral, merger, and ringdown in LIGO-Virgo data from 2009-2010

We report a search for gravitational waves from the inspiral, merger and ringdown of binary black holes (BBH) with total mass between 25 and 100 solar masses, in data taken at the LIGO and Virgo observatories between July 7, 2009 and October 20, 2010. The maximum sensitive distance of the detectors over this period for a (20, 20)M-circle dot coalescence was 300 Mpc. No gravitational wave signals w

V/P SPECT as a diagnostic tool for pregnant women with suspected pulmonary embolism.

The purpose of the study was to assess the prevalence of pulmonary embolism (PE) and other lung diseases among pregnant women with suspected PE and to calculate the radiation exposure to patient and fetus in this population. As a secondary aim, we evaluated the negative predictive value of a normal ventilation/perfusion single photon emission computed tomography (V/P SPECT) examination in pregnanc

Effects of a 3-year intervention: The Copenhagen School Child Intervention Study.

INTRODUCTION: This study assessed short and long term effects of a 3-year controlled school-based physical activity (PA) intervention on fatness, cardiorespiratory fitness (VO2peak) and cardiovascular disease (CVD) risk factors in children. METHODS: The study involved 18 schools (10 intervention and 8 controls) and included a follow-up 4 years after the end of intervention. The analyses included 6

Singular-Value Decomposition of Solution Operators to Model Evolution Equations

We consider evolution equations generated by quadratic operators admitting a decomposition in creation-annihilation operators without usual ellipticity-type hypotheses; this class includes hypocoercive model operators. We identify the singular-value decomposition of their solution operators with the evolution generated by an operator of harmonic oscillator type, and in doing so derive exact charac

The Composition of Plant Mitochondrial Supercomplexes Changes with Oxygen Availability

Background: Respiratory supercomplexes are known to exist, but their function remains to be revealed. Results: Plant supercomplexes are affected by hypoxia and a concomitant drop in pH. Conclusion: Respiratory supercomplexes are dynamic structures that are affected by the intracellular environment. Significance: Supercomplexes could have a regulatory function in guiding electrons through alternati

Rituximab versus Cyclophosphamide in ANCA-Associated Renal Vasculitis.

Background: Cyclophosphamide induction regimens for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis are effective in 70 to 90% of patients, but they are associated with high rates of death and adverse events. Treatment with rituximab has led to remission rates of 80 to 90% among patients with refractory ANCA-associated vasculitis and may be safer than cyclophosphamide regimens. Me

Secreted enzymatic activities of ectomycorrhizal fungi as a case study of functional diversity and functional redundancy

Introduction Many studies deal with taxonomic diversity (TD) or estimation of functional traits of ectomycorrhizal communities. However, to our knowledge, none of them has ever tried to calculate the functional diversity (FD) of those communities, which is of critical importance for the diversity and reliability of nutrient supply to the tree. Objectives Here, we propose to evaluate the functional

Measuring overload effects during fatigue crack growth in bainitic steel by synchrotron X-ray diffraction

In this work we present the results of in situ synchrotron X-ray diffraction measurements of fatigue crack-tip strain fields following a 100% overload (OL) under plane strain conditions. The study is made on a bainitic steel with a high toughness and fine microstructure. This allowed a very high (60 mu m) spatial resolution to be achieved so that fine-scale changes occurring around the crack-tip w

Complex selection associated with Hox genes in a natural population of lizards

Hox genes are recognized for their explanatory power of bilateral development. However, relatively little is known about natural variation in, and the evolutionary dynamics of, Hox genes within wild populations. Utilizing a natural population of sand lizards (Lacerta agilis), we screened HoxA13 for genetic variation and an association with incidence of offspring malformations. We found significant

A reduced-order ODE-PDE model for the activated sludge process in wastewater treatment: Classification and stability of steady states

Most wastewater treatment plants contain an activated sludge process, which consists of a biological reactor and a sedimentation tank. The purpose is to reduce the incoming organic material and dissolved nutrients (the substrate). This is done in the biological reactor where micro-organisms (the biomass) decompose the substrate. The biomass is then separated from the water in the sedimentation tan

The Dynamic Association Processes Leading from a Silica Precursor to a Mesoporous SBA-15 Material.

During the last two decades, the synthesis of silica with an ordered mesoporous structure has been thoroughly explored. The basis of the synthesis is to let silica monomers polymerize in the presence of an amphiphilic template component. In the first studies, cationic surfactants were used as structure inducer. Later it was shown that pluronic copolymers also could have the role. One advantage wit

Diffraction-limited storage rings - a window to the science of tomorrow.

This article summarizes the contributions in this special issue on Diffraction-Limited Storage Rings. It analyses the progress in accelerator technology enabling a significant increase in brightness and coherent fraction of the X-ray light provided by storage rings. With MAX IV and Sirius there are two facilities under construction that already exploit these advantages. Several other projects are

Buyer-supplier relationships in industrialized building

Close collaboration is considered important; but is close collaboration for all purchases necessary to create value-in-production? In construction as well as in other industries, companies purchase a variety of items that require different amounts of attention to the relationship with suppliers. Buyer-supplier relationships are investigated in relation to how they bring value-in-production in the

Subtle Monte Carlo Updates in Dense Molecular Systems

Although Markov chain Monte Carlo (MC) simulation is a potentially powerful approach for exploring conformational space, it has been unable to compete with molecular dynamics (MD) in the analysis of high density structural states, such as the native state of globular proteins. Here, we introduce a kinetic algorithm, CRISP, that greatly enhances the sampling efficiency in all-atom MC simulations of

A Combinatorial Algorithm for All-Pairs Shortest Paths in Directed Vertex-Weighted Graphs with Applications to Disc Graphs

We consider the problem of computing all-pairs shortest paths in a directed graph with non-negative real weights assigned to vertices. For an n x n 0 - 1 matrix C, let K-C be the complete weighted graph on the rows of C where the weight of an edge between two rows is equal to their Hamming distance. Let MWT(C) be the weight of a minimum weight spanning tree of K-C. We show that the all-pairs short

Inflammatory Ly-6C(hi) monocytes play an important role in the development of severe transplant arteriosclerosis in hyperlipidemic recipients

Objective: Transplant arteriosclerosis (TA) restricts long-term survival of heart transplant recipients. Although the role of monocyte/macrophages is well established in native atherosclerosis, it has been studied to a much lesser extent in TA. Plasma cholesterol is the most important non-immunologic risk factor for development of TA but the underlying mechanisms are largely unknown. We hypothesiz

REST mediates androgen receptor actions on gene repression and predicts early recurrence of prostate cancer.

The androgen receptor (AR) is a key regulator of prostate tumorgenesis through actions that are not fully understood. We identified the repressor element (RE)-1 silencing transcription factor (REST) as a mediator of AR actions on gene repression. Chromatin immunoprecipitation showed that AR binds chromatin regions containing well-characterized cis-elements known to mediate REST transcriptional rep
