Search for pair production of massive particles decaying into three quarks with the ATLAS detector in root s=7 TeV pp collisions at the LHC

A search is conducted for hadronic three-body decays of a new massive coloured particle in root s = 7 TeV p p collisions at the LHC using an integrated luminosity of 4.6 fb(-1) collected by the ATLAS detector. Supersymmetric gluino pair production in the context of a model with R-parity violation is used as a benchmark scenario. The analysis is divided into two search channels, each optimised sepa

RNA sequencing of sarcomas with simple karyotypes: identification and enrichment of fusion transcripts.

Gene fusions are neoplasia-associated mutations arising from structural chromosomal rearrangements. They have a strong impact on tumor development and constitute important diagnostic markers. Malignant soft tissue tumors (sarcomas) constitute a heterogeneous group of neoplasms with >50 distinct subtypes, each of which is rare. In addition, there is considerable morphologic overlap between sarcomas

Laser-Induced Fluorescence Detection of Hot Molecular Oxygen in Flames Using an Alexandrite Laser

The use of an alexandrite laser for laser-induced fluorescence (LIF) spectroscopy and imaging of molecular oxygen in thermally excited vibrational states is demonstrated. The laser radiation after the third harmonic generation was used to excite the B-X (0-7) band at 257 nm in the Schumann-Runge system of oxygen. LIF emission was detected between 270 and 380 nm, revealing distinct bands of the tra

The LEAF questionnaire: a screening tool for the identification of female athletes at risk for the female athlete triad

Background Low energy availability (EA) in female athletes with or without an eating disorder (ED) increases the risk of oligomenorrhoea/functional hypothalamic amenorrhoea and impaired bone health, a syndrome called the female athlete triad (Triad). There are validated psychometric instruments developed to detect disordered eating behaviour (DE), but no validated screening tool to detect persiste

Mergers and acquisitions as embedded network activities

This paper introduces a network perspective to Mergers and Acquisitions (M&As). The literature on M&As commonly focuses on only the parties directly involved in mergers and acquisitions, while the present perspective points to M&As as embedded activities. The paper provides empirical illustrations from 12 acquisitions to indicate the consequences when M&A studies acknowledge busine

Search for charged Higgs bosons through the violation of lepton universality in t(t)over-bar events using pp collision data at root s=7 TeV with the ATLAS experiment

In several extensions of the Standard Model, the top quark can decay into a bottom quark and a light charged Higgs boson H+, t -> bH(+), in addition to the Standard Model decay t -> bW. Since W bosons decay to the three lepton generations equally, while H+ may predominantly decay into tau nu, charged Higgs bosons can be searched for using the violation of lepton universality in top quark decays. T

Structure and Dynamics of Loosely Cross-Linked Ionic Microgel Dispersions in the Fluid Regime

We report a comprehensive experimental-theoretical study of the temperature-and concentration-dependent swelling behavior of weakly cross-linked PNiPAm ionic microgel particles in the deionized fluid phase. The particles swell reversibly when the dispersion is cooled from the collapsed state to lower temperatures. While the collapsed state shows no dependence on the microgel number density, the sw

Liming in a beech forest results in more mineral elements stored in the mantle of Lactarius subdulcis ectomycorrhizas.

Liming is a forest practice used to counteract forest decline induced by soil acidification. It consists of direct Ca and Mg input in forest soil and restores tree mineral nutrition, but also causes drastic changes in nutrient availability in soil. Ectomycorrhizal (ECM) fungi significantly contribute in nutrient uptake by trees, and can recover them through organic acid secretion or through enzyma

2-year follow-up report on micromotion of a short tibia stem.

Background and purpose - A shortened tibial stem could influence the early prosthetic fixation. We therefore compared the short stem to the standard-length stem using radiostereometric analysis (RSA) as primary outcome measure. Patients and methods - 60 patients were randomized to receive a cemented Triathlon total knee arthroplasty (TKA) with a tibial tray of either standard or short stem length.

Conformational dynamics and thermodynamics of protein-ligand binding studied by NMR relaxation.

Protein conformational dynamics can be critical for ligand binding in two ways that relate to kinetics and thermodynamics respectively. First, conformational transitions between different substates can control access to the binding site (kinetics). Secondly, differences between free and ligand-bound states in their conformational fluctuations contribute to the entropy of ligand binding (thermodyna

Exponential Time Complexity of the Permanent and the Tutte Polynomial

We show conditional lower bounds for well-studied #P-hard problems: -The number of satisfying assignments of a 2-CNF formula with n variables cannot be computed in time exp(o(n)), and the same is true for computing the number of all independent sets in an n-vertex graph. -The permanent of an n x n matrix with entries 0 and 1 cannot be computed in time exp(o(n)). -The Tutte polynomial of an n-verte

Context gateway for physical spaces

Context-aware computing applications dynamically change their behaviors based on the context data and services provided by multiple physical spaces in the real world, such as persons, shops, homes and offices. In this paper, we propose a generic context gateway framework to manage these heterogeneous physical spaces of context sources. The framework forms a key enabling component of a scalable con

Plasma concentrations of Gas6 (growth arrest specific protein 6) and its soluble tyrosine kinase receptor sAxl in sepsis and systemic inflammatory response syndromes

Introduction: Gas6, the protein product of the growth arrest specific gene 6, is present in human circulation at subnanomolar concentrations. It is secreted by endothelial cells and is important for the activation of endothelium during inflammation. Axl, the tyrosine kinase receptor for Gas6, is also present in endothelium and can be cleaved and released into the circulation. The soluble of form A

Valuing Supporting Soil Ecosystem Services in Agriculture: A Natural Capital Approach

Soil biodiversity through its delivery of ecosystem functions and attendant supporting ecosystem services-benefits soil organisms generate for farmers-underpins agricultural production. Yet lack of practical methods to value the long-term effects of current farming practices results, inevitably, in short-sighted management decisions. We present a method for valuing changes in supporting soil ecosy

Effect of Precision on Longitudinal Follow-Up of Bone Mineral Density Measurements in Elderly Women and Men.

Precision error of dual-energy X-ray absorptiometry exceeds the expected annual rate of bone loss in the elderly. The capacity to detect changes in areal bone mineral density (aBMD; g/cm(2)) over a 5-yr period was assessed. Six hundred ninety-one women, 75.2 (0.1)yr, from the Malmö OPRA-study, were measured using Lunar DPX-L (GE Lunar, Madison, WI), and 211 men, 74.7 (3.2)yr, from the Malmö Mr Os-

Giving notice to employability

The neoliberal notion of employability has risen to prominence over the past 20 years, having been positioned as the crux of national, organizational and individual prosperity. To be employable, individuals are increasingly called upon to be self-reliant; aligning themselves to the conditions of an ostensibly fast-moving and precarious global economy. This special issue of ephemera calls attention

Combined effects of age of onset and input on the development of different grammatical structures: A study of simultaneous and successive acquisition of French

This study investigates the combined effects of Age of Onset of Acquisition (AOA) and quality and quantity of input on the development of three grammatical structures in French. In a longitudinal and multiple case study including successive (L2) Swedish-French bilingual children (n=3), simultaneous (2L1) Swedish-French bilingual children (n=3) and monolingual French children (n=3), we examine the
