Search for a heavy neutral particle decaying into an electron and a muon using 1 fb(-1) of ATLAS data

A search is presented for a high mass neutral particle that decays directly to the e(+/-) mu(-/+) final state. The data sample was recorded by the ATLAS detector in root s = 7 TeV pp collisions at the LHC from March to June 2011 and corresponds to an integrated luminosity of 1.07 fb(-1). The data are found to be consistent with the Standard Model background. The high e(+/-) mu(-/+) mass region is

Measurement of the t(t)over-bar production cross section in the tau plus jets channel using the ATLAS detector

A measurement of the top quark pair production cross section in the final state with a hadronically decaying tau lepton and jets is presented. The analysis is based on proton-proton collision data recorded by the ATLAS experiment at the LHC, with a centre-of-mass energy of 7 TeV. The data sample corresponds to an integrated luminosity of 1.67 fb(-1). The cross section is measured to be sigma(t (t)

Diffusion length measurements in axial and radial heterostructured nanowires using cathodoluminescence

We have measured the ambipolar diffusion lengths in nanowires with GaAs and AlGaAs core material using cathodoluminescence imaging. This was done by combining III-V semiconductor materials with different bandgaps in single nanowires. We show that it is possible to record intensity profiles of the emission from segments of lower bandgap material positioned along the nanowire length and in this way

t(6;9)(p22; q34)/DEK-NUP214-rearranged pediatric myeloid leukemia: an international study of 62 patients

Acute myeloid leukemia with t(6; 9)(p22; q34) is listed as a distinct entity in the 2008 World Health Organization classification, but little is known about the clinical implications of t(6; 9)-positive myeloid leukemia in children. This international multicenter study presents the clinical and genetic characteristics of 62 pediatric patients with t(6; 9)/DEKNUP214-rearranged myeloid leukemia; 54

Characterization of a two-color pump-probe setup at FLASH using a velocity map imaging spectrometer

We report on the implementation of a high-count-rate charged particle imaging detector for two-color pump-probe experiments at the free electron laser in Hamburg (FLASH). In doing so, we have developed a procedure for finding the spatial and temporal overlap between the extreme UV free electron laser (FEL) pulses and the IR pulses, which allows for complete alignment of the setup in situations whe

Associations between mass media exposure and birth preparedness among women in southwestern Uganda: a community-based survey.

Background : Exposure to mass media provides increased awareness and knowledge, as well as changes in attitudes, social norms and behaviors that may lead to positive public health outcomes. Birth preparedness (i.e. the preparations for childbirth made by pregnant women, their families, and communities) increases the use of skilled birth attendants (SBAs) and hence reduces maternal morbidity and mo

Early amplitude-integrated EEG correlates with cord TNF-alpha and brain injury in very preterm infants

Aim: To investigate if the early electroencephalogram (EEG) and amplitude-integrated EEG (aEEG) in very preterm infants is affected by perinatal inflammation and brain injury, and correlates with long-term outcome. Methods: Sixteen infants born at 24-28 gestational weeks (median 25.5) had continuous EEG/aEEG during the first 72 h of life. Minimum and maximum EEG interburst intervals (IBI), and aEE

A 60 GHz receiver front-end with PLL based phase controlled LO generation for phased-arrays

This paper presents a front-end architecture for fully integrated 60 GHz phased array receivers. It employs LO-path beamforming using a phase controlled phase-locked loop (PC-PLL). To demonstrate the architecture a circuit is implemented featuring a two stage low noise amplifier, two cascaded active mixers, and a PC-PLL. The receiver downconverts the 60 GHz signal in two steps, using LO signals fr

Infarct quantification using 3D inversion recovery and 2D phase sensitive inversion recovery; validation in patients and ex vivo.

Cardiovascular-MR (CMR) is the gold standard for quantifying myocardial infarction using late gadolinium enhancement (LGE) technique. Both 2D- and 3D-LGE-sequences are used in clinical practise and in clinical and experimental studies for infarct quantification. Therefore the aim of this study was to investigate if image acquisitions with 2D- and 3D-LGE show the same infarct size in patients and e

Sexual patterns of prebreeding energy reserves in the common frog Rana temporaria along a latitudinal gradient

The ability to store energy is an important life history trait for organisms facing long periods without energy income, and in particular for capital breeders such as temperate zone amphibians, which rely on stored energy during reproduction. However, large scale comparative studies of energy stores in populations with different environmental constraints on energy allocation are scarce. We investi

Back and neck pain: Patterns in healthcare consultations

Musculoskeletal disorders are very common and affects the individual by pain and functional impairment, and the society through work disability and healthcare utilisation. To what extent is less studied. Routinely collected healthcare registers is a potential resource for epidemiological studies of musculoskeletal disorders. Skåne region, as opposed to nationally in Sweden, has healthcare register

Characterization of Vehicle-to-Vehicle Radio Channels from Measurements at 5.2GHz

The development of efficient vehicle-to-vehicle (V2V) communications systems requires an understanding of the underlying propagation channels. In this paper, we present results on pathloss, power-delay profiles (PDPs), and delay-Doppler spectra from a high speed measurement campaign on a highway in Lund, Sweden. Measurements were performed at a carrier frequency of 5.2GHz with the communicating ve

Resistant starch in common starchy foods as an alternative to increase dietary fibre intake

Nutritional classification of dietary saccharides considers as indigestible saccharides those that are incompletely or not absorbed in small intestine. Resistant starch (RS) as a part of dietary fibre (DF) is a type of indigestible saccharide. The addition of natural RS from some fruits, legumes or cereals to commonly eaten starchy foods is a good alternative to increase the DF intake representing

Loss of collectivity in the transitional Er-156 nucleus at high spin

The Cd-114(Ca-48, 6n gamma) reaction at 215 MeV has been investigated using the Gammasphere spectrometer to study the high-spin structure of the nucleus Er-156(68)88. Many new transitions have been established along with 68 definitive spin-parity level assignments from a high-fold angular-distribution analysis. In addition, absolute B(M 1) and B(E 1) strengths have been inferred from measured gamm

Computational Insights on Sulfonamide Imprinted Polymers

Molecular imprinting is one of the most efficient methods for preparing synthetic receptors that possess user defined recognition properties. Despite general success of non-covalent imprinting for a large variety of templates, some groups of compounds remain difficult to tackle due to their structural complexity. In this study we investigate preparation of molecularly imprinted polymers that can b

Defining energy security takes more than asking around

Abstract in UndeterminedThe recent contribution by Benjamin Sovacool proposes 20 dimensions and 320 indicators of energy security in Asia. However, the method for identifying these dimensions and indicators – 64 semi-structured interviews – has three shortcomings. First, Asian policy makers responsible for energy security are absent from the pool of respondents dominated by academics. Second, no p
