We present a search for a light (mass < 2 GeV) boson predicted by Hidden Valley supersymmetric models that decays into a final state consisting of collimated muons or electrons, denoted "lepton-jets". The analysis uses 5 fb(-1) of root s = 7 TeV proton-proton collision data recorded by the ATLAS detector at the Large Hadron Collider to search for the following signatures: single lepton-jets with a
Non-negative matrix factorization (NMF) condenses high-dimensional data into lower-dimensional models subject to the requirement that data can only be added, never subtracted. However, the NMF problem does not have a unique solution, creating a need for additional constraints (regularization constraints) to promote informative solutions. Regularized NMF problems are more complicated than conventio
This letter reports on a search for hypothetical heavy neutrinos, N, and right-handed gauge bosons, W-R, in events with high transverse momentum objects which include two reconstructed leptons and at least one hadronic jet. The results were obtained from data corresponding to an integrated luminosity of 2.1 fb(-1) collected in proton-proton collisions at root s = 7 TeV with the ATLAS detector at t
The purpose of this study was to investigate women's wishes and need for knowledge concerning sexuality and relationships in connection with gynecological cancer. A total of 11 women were interviewed following the completion of their treatment for gynecological cancer. The data was analyzed using latent content analysis. Two main categories were identified: "The absence of knowledge about the body
Fisher 344 rats with implanted N29 glioma tumours were treated with Pulsed Electric Fields (PEF) in combination with immunization using either IFN-gamma-gene-transfected syngeneic tumour cells or IFN-gamma transfected N29 cells treated with 10 micro-M 5-aza-2-deoxycytidine (DAC). Tumours (N29) were inoculated subcutaneously on both thighs of female F- 344 syngeneic rats. The left tumour was treate
A quadrature voltage controlled oscillator (QVCO) topology exhibiting low power consumption and high phase noise performance at low supply voltages is presented. The QVCO buffer includes varactors to maximize the output voltage and minimize the current consumption. Microstrip theory and the principle of conservation of energy have been used to evaluate the distributed capacitances of symmetrical i

Purpose: Previous studies have shown that spinal alpha1-adrenoceptors can influence voiding in normal rats and in rats with outlet obstruction. Also, at the supraspinal level such receptors may be involved in voiding control. Therefore, we studied in rats the effects on cystometrography of intracerebroventricular administered alpha1-adrenoceptor antagonists. Materials and Methods: Continuous cysto
Numerous past studies investigating the performance of hedge funds suffer from two distinct problems: unreliable and biased return data inherent in virtually all databases and the use of static asset-pricing models. Using “indexes of indexes” for our hedge fund returns, both free of biases and highly representative, we investigate which risk factors investors are exposed to and whether hedge fund
The estimated number of children who are utilised as child soldiers all over the world is 250,000 today. Based on the Coalition to Stop the Use of Child Soldiers research children were used in armed conflicts in 20 countries from 2004-2007. One of the most prominent nations involving the use of child soldiers is the Democratic Republic of the Congo. It is estimated, that 40% of them are girls, who
Sixty-six patients operated on for isolated cleft palate were evaluated as adults, and their speech was assessed clinically. Forty-four had undergone a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at the age of 18 months. Speech was judged subjectively by the patients themselves, and perceptual assessment was made by three speech pathologists. The remaining speech problems,
Maturity-onset diabetes of the young (MODY) is a heterogeneous single gene disorder characterized by non–insulin-dependent diabetes, an early onset and autosomal dominant inheritance. Mutations in six genes have been shown to cause MODY. Approximately 15–20% of families fitting MODY criteria do not have mutations in any of the known genes. These families provide a rich resource for the identificat
Objective: This study evaluated the quality and readability of English-language internet information for adults with hearing impairment and their significant others. Design: Two keyword pairs (hearing loss and hearing aids) were entered into five country-specific versions of the most commonly used internet search engine in May 2011. Sample: For each of the 10 searches, the first 10 relevant websit
Arsenic is among the most toxic elements and it commonly exists in water as arsenite (As(III)) and arsenate (As(V)) ions. As(III) removal often requires a pre-oxidation or pH adjustment step and it is a challenge to adsorb As(III) at circumneutral pH. In this study, iron-aluminium double hydrous oxides were synthesized and incorporated into cryogels. The resulting composite cryogels were evaluated
An updated search is performed for gluino, top squark, or bottom squark R-hadrons that have come to rest within the ATLAS calorimeter, and decay at some later time to hadronic jets and a neutralino, using 5.0 and 22.9 fb(-1) of pp collisions at 7 and 8 TeV, respectively. Candidate decay events are triggered in selected empty bunch crossings of the LHC in order to remove pp collision backgrounds. S
Hydration free energy calculations are often used to validate molecular simulation methodologies and molecular mechanics force fields. We use the free-energy perturbation method together with the AMOEBA polarizable force field and the Poltype parametrization protocol to predict the hydration free energies of 52 molecules as part of the SAMPL4 blind challenge. For comparison, similar calculations a
