Viscoelastic vibration damping identification methods. Application to laminated glass

AbstractLaminated glass is composed of two glass layers and a thin intermediate PVB layer, strongly influencing PVB's viscoelastic behaviour its dynamic response. While natural frequencies are relatively easily identified even with simplified FE models, damping ratios are not identified with such an ease. In order to determine to what extent external factors influence damping identification, different tests have been carried out. The external factors considered, apart from temperature, are accelerometers, connection cables and the effect of the glass layers. To analyse the influence of the accelerometers and their connection cables a laser measuring device was employed considering three possibilities: sample without instrumentation, sample with the accelerometers fixed and sample completely instrumented. When the sample is completely instrumented, accelerometer readings are also analysed. To take into consideration the effect of the glass layers, tests were realised both for laminated glass and monolithic samples. This paper presents in depth data analysis of the different configurations and establishes criteria for data acquisition when testing laminated glass
Inflationary solution to the strong CP and μ problems

AbstractWe show that the vacuum expectation value of the inflaton at the Peccei–Quinn axion scale can generate the supersymmetric Higgs mass μ term. This provides an inflationary simultaneous solution to the strong CP problem and the μ problem of the minimal supersymmetric Standard Model, and gives a testable prediction for the μ parameter: μ2≈(0.25–0.5)m02, where m0 is the soft Higgs scalar mass. Our model involves a very small Yukawa coupling of order 10−10, which could originate from an extra-dimensional scenario or type I string theory
n-Hexane Bromination Using Barium Fluorobromate Ba(BrF4)2

AbstractIt was observed that Ba(BrF4)2 demonstrates a high reactivity towards n-hexane. It was found that the heating the reaction mass proceed with intensive self-heating up to 40°C and release of elemental bromine. The GC-MS analysis showed that the main product of Ba(BrF4)2 interaction with n-hexane is 3-bromohexane. The optimal interaction parameters were found. The heat effect of the reaction was determined by isothermal calorimetric method, it was –1451kJ/mole. The qualitative composition of solid precipitate was determined by EDXRF and XRD analyses. BaF2 is formed as only solid product of the reaction between Ba(BrF4)2 and n-hexane. It was found that conditions of researched reaction are quite unusual for known free-radical hydrogen substitution processes in case of alkanes. Also we can conclude that Ba(BrF4)2 is much more soft reagent is case of interaction with alkanes in comparison with BrF3 and it can provide more or less selective bromination of alkane unlikely to BrF3
Measurement of the inclusive ϕ cross-section in pp collisions at s=7 TeV

AbstractThe cross-section for inclusive ϕ meson production in pp collisions at a centre-of-mass energy of s=7 TeV has been measured with the LHCb detector at the Large Hadron Collider. The differential cross-section is measured as a function of the ϕ transverse momentum pT and rapidity y in the region 0.6<pT<5.0 GeV/c and 2.44<y<4.06. The cross-section for inclusive ϕ production in this kinematic range is σ(pp→ϕX)=1758±19(stat)−14+43(syst)±182(scale) μb, where the first systematic uncertainty depends on the pT and y region and the second is related to the overall scale. Predictions based on the Pythia 6.4 generator underestimate the cross-section
Childhood outcomes after prescription of antibiotics to pregnant women with spontaneous preterm labour: 7-year follow-up of the ORACLE II trial

SummaryBackgroundThe ORACLE II trial compared the use of erythromycin and/or amoxicillin–clavulanate (co-amoxiclav) with that of placebo for women in spontaneous preterm labour and intact membranes, without overt signs of clinical infection, by use of a factorial randomised design. The aim of the present study—the ORACLE Children Study II—was to determine the long-term effects on children after exposure to antibiotics in this clinical situation.MethodsWe assessed children at age 7 years born to the 4221 women who had completed the ORACLE II study and who were eligible for follow-up with a structured parental questionnaire to assess the child's health status. Functional impairment was defined as the presence of any level of functional impairment (severe, moderate, or mild) derived from the mark III Multi-Attribute Health Status classification system. Educational outcomes were assessed with national curriculum test results for children resident in England.FindingsOutcome was determined for 3196 (71%) eligible children. Overall, a greater proportion of children whose mothers had been prescribed erythromycin, with or without co-amoxiclav, had any functional impairment than did those whose mothers had received no erythromycin (658 [42·3%] of 1554 children vs 574 [38·3%] of 1498; odds ratio 1·18, 95% CI 1·02–1·37). Co-amoxiclav (with or without erythromycin) had no effect on the proportion of children with any functional impairment, compared with receipt of no co-amoxiclav (624 [40·7%] of 1523 vs 608 [40·0%] of 1520; 1·03, 0·89–1·19). No effects were seen with either antibiotic on the number of deaths, other medical conditions, behavioural patterns, or educational attainment. However, more children whose mothers had received erythromycin or co-amoxiclav developed cerebral palsy than did those born to mothers who received no erythromycin or no co-amoxiclav, respectively (erythromycin: 53 [3·3%] of 1611 vs 27 [1·7%] of 1562, 1·93, 1·21–3·09; co-amoxiclav: 50 [3·2%] of 1587 vs 30 [1·9%] of 1586, 1·69, 1·07–2·67). The number needed to harm with erythromycin was 64 (95% CI 37–209) and with co-amoxiclav 79 (42–591).InterpretationThe prescription of erythromycin for women in spontaneous preterm labour with intact membranes was associated with an increase in functional impairment among their children at 7 years of age. The risk of cerebral palsy was increased by either antibiotic, although the overall risk of this condition was low.FundingUK Medical Research Council
Influence of Metalworking Defect in Knee Cruciate Ligament Screws as a Possible Origin of Infections.

AbstractA bone mucormycosis outbreak in a clinic of Paraná city after arthroscopic knee anterior cruciate ligament reconstruction forced to suspend these interventions. The main candidates as the infection source were the implanted screws. These screws were metallurgically analyzed. Microscopic defects like burrs and bending's were found within the screw's Allen heads. According to previous report Spector et al. (2013), these defects protect microorganisms and make difficult to eliminate them. The aim of this work was to demonstrate the implication of metal working defects in the titanium fixing screws as a reservoir of contaminated machining oil which could be the possible transmitting vehicle in the outbreak of bone mucormycosis. The genetic relatedness of the isolated strains was established, favoring the hypothesis that contaminated screws might be the infection sources
The plasters of the Sacro Monte of Varallo Sesia. From the characterisation to the proposition of a restorative mix

AbstractIn this paper, the systematic physical-chemical characterisation of historical plasters of the Sacro Monte of Varallo Sesia, Italy, the study of the local constructive techniques, as well as the evaluation of new restoration plasters is presented.The selected samples (from XVI to XVIIIth centuries) are in a quite good state of conservation despite the prolonged exposition to weathering agents. This behaviour is due to the good manufacturing and to the peculiar smooth finishing layers which reduce water permeability and allow water drops to slide off.The plasters characterisation realised in laboratory for in situ integration is also presented. These plasters should meet functional and aesthetical requirements and must satisfy the compatibility issues not only related to the physical-chemical aspects
Inequalities in mental health and well-being in a time of austerity: Baseline findings from the Stockton-on-Tees cohort study

AbstractSince 2010, the UK has pursued a policy of austerity characterised by public spending cuts and welfare changes. There has been speculation – but little actual research – about the effects of this policy on health inequalities. This paper reports on a case study of local health inequalities in the local authority of Stockton-on-Tees in the North East of England, an area characterised by high spatial and socio-economic inequalities. The paper presents baseline findings from a prospective cohort study of inequalities in mental health and mental wellbeing between the most and least deprived areas of Stockton-on-Tees. This is the first quantitative study to explore local mental health inequalities during the current period of austerity and the first UK study to empirically examine the relative contributions of material, psychosocial and behavioural determinants in explaining the gap. Using a stratified random sampling technique, the data was analysed using multi-level models that explore the gap in mental health and wellbeing between people from the most and least deprived areas of the local authority, and the relative contributions of material, psychosocial and behavioural factors to this gap. The main findings indicate that there is a significant gap in mental health between the two areas, and that material and psychosocial factors appear to underpin this gap. The findings are discussed in relation to the context of the continuing programme of welfare changes and public spending cuts in the UK
Measurement of angular correlations in Drell–Yan lepton pairs to probe Z/γ⁎ boson transverse momentum at s=7 TeV with the ATLAS detector

AbstractA measurement of angular correlations in Drell–Yan lepton pairs via the ϕη⁎ observable is presented. This variable probes the same physics as the Z/γ⁎ boson transverse momentum with a better experimental resolution. The Z/γ⁎→e+e− and Z/γ⁎→μ+μ− decays produced in proton–proton collisions at a centre-of-mass energy of s=7 TeV are used. The data were collected with the ATLAS detector at the LHC and correspond to an integrated luminosity of 4.6 fb−1. Normalised differential cross sections as a function of ϕη⁎ are measured separately for electron and muon decay channels. These channels are then combined for improved accuracy. The cross section is also measured double differentially as a function of ϕη⁎ for three independent bins of the Z boson rapidity. The results are compared to QCD calculations and to predictions from different Monte Carlo event generators. The data are reasonably well described, in all measured Z boson rapidity regions, by resummed QCD predictions combined with fixed-order perturbative QCD calculations or by some Monte Carlo event generators. The measurement precision is typically better by one order of magnitude than present theoretical uncertainties
A bulk inflaton from large-volume extra dimensions

AbstractThe universe may have extra spatial dimensions with large volume that we cannot perceive because the energy required to excite modes in the extra directions is too high. Many examples are known of manifolds with a large volume and a large mass gap. These compactifications can help explain the weakness of four-dimensional gravity and, as we show here, they also have the capacity to produce reasonable potentials for an inflaton field. Modeling the inflaton as a bulk scalar field, it becomes very weakly coupled in four dimensions and this enables us to build phenomenologically acceptable inflationary models with tunings at the few per mil level. We speculate on dark matter candidates and the possibility of braneless models in this setting
Gamification in Factory Management Education – A Case Study with Lego Mindstorms

AbstractResearch oriented teaching in universities provides opportunities to support the student's desire to explore. A student's learning success can benefit from gamified project work, especially when students face self-guided learning processes in demanding educational activities. Gamification is defined as the use of game elements in a non-game context. Games offer the chance to improve the motivation of students, support group work, train communication skills and introduce the capacity for experimenting in safe environments. Therefore the learning effect of prospective engineers can be increased through the integration of Gamification into educational activities. This leads to higher student participation in university courses and encourages the development of the student's social, personal and technical competences. In this paper a game concept for teaching in universities is introduced focusing on the impartment of the state of the art on manufacturing for value creation, e.g. production planning and control. The concept covers a level based storyline with rules and goals using physical artefacts of Lego Mindstorms. Due to the modular characteristic of Lego, which supports creativity by having a high number of possible combinations, a “free playing space” for students is established. In groups, the students work in a highly problem oriented way, e.g. finding cost savings for their factory due to a changing market condition. Feedback in the sense of the success of student's strategies is given directly through the designed Lego model and its functionality
β-lactamases produced by amoxicillin-clavulanate-resistant enterobacteria isolated in Buenos Aires, Argentina: A new blaTEM gene

AbstractResistance to β-lactam/β-lactamase inhibitors in enterobacteria is a growing problem that has not been intensively studied in Argentina.In the present work, 54/843 enterobacteria collected in a teaching hospital of Buenos Aires city were ampicillin-sulbactam-resistant isolates remaining susceptible to second- and third-generation cephalosporins. The enzymatic mechanisms present in the isolates, which were also amoxicillin-clavulanic acid (AMC)-resistant (18/54) were herein analyzed.Sequencing revealed two different variants of blaTEM-1, being blaTEM-1b the most frequently detected allelle (10 Escherichia coli, 3 Klebsiella pneumoniae, 2 Proteus mirabilis and 1 Raoultella terrigena) followed by blaTEM-1a (1 K. pneumoniae). Amoxicillin-clavulanate resistance seems to be mainly associated with TEM-1 overproduction (mostly in E. coli) or co-expressed with OXA-2-like and/or SHV β-lactamases (K. pneumoniae and P. mirabilis).A new blaTEM variant (TEM-163) was described in an E. coli strain having an AMC MIC value of 16/8μg/ml. TEM-163 contains Arg275Gln and His289Leu amino acid substitutions. On the basis of the high specific activity and low IC50 for clavulanic acid observed, the resistance pattern seems to be due to overproduction of the new variant of broad spectrum β-lactamase rather than to an inhibitor-resistant TEM (IRT)-like behavior
The two-loop electroweak bosonic corrections to sin2⁡θeffb

AbstractThe prediction of the effective electroweak mixing angle sin2⁡θeffb in the Standard Model at two-loop accuracy has now been completed by the first calculation of the bosonic two-loop corrections to the Zb¯b vertex. Numerical predictions are presented in the form of a fitting formula as function of MZ,MW,MH,mt and Δα, αs. For central input values, we obtain a relative correction of Δκb(α2,bos)=−0.9855×10−4, amounting to about a quarter of the fermionic corrections, and corresponding to sin2⁡θeffb=0.232704. The integration of the corresponding two-loop vertex Feynman integrals with up to three dimensionless parameters in Minkowskian kinematics has been performed with two approaches: (i) Sector decomposition, implemented in the packages FIESTA 3 and SecDec 3, and (ii) Mellin–Barnes representations, implemented in AMBRE 3/MB and the new package MBnumerics
Search for high-mass new phenomena in the dilepton final state using proton–proton collisions at s=13TeV with the ATLAS detector

AbstractA search is conducted for both resonant and non-resonant high-mass new phenomena in dielectron and dimuon final states. The search uses 3.2fb−1 of proton–proton collision data, collected at s=13TeV by the ATLAS experiment at the LHC in 2015. The dilepton invariant mass is used as the discriminating variable. No significant deviation from the Standard Model prediction is observed; therefore limits are set on the signal model parameters of interest at 95% credibility level. Upper limits are set on the cross-section times branching ratio for resonances decaying to dileptons, and the limits are converted into lower limits on the resonance mass, ranging between 2.74 TeV and 3.36 TeV, depending on the model. Lower limits on the ℓℓqq contact interaction scale are set between 16.7 TeV and 25.2 TeV, also depending on the model

Note: Fast compact laser shutter using a direct current motor and three-dimensional printing

We present a mechanical laser shutter design that utilizes a direct current electric motor to rotate a blade which blocks and unblocks a light beam. The blade and the main body of the shutter are modeled with computer aided design (CAD) and are produced by 3D printing. Rubber flaps are used to limit the blade’s range of motion, reducing vibrations and preventing undesirable blade oscillations. At its nominal operating voltage, the shutter achieves a switching speed of (1.22 ± 0.02) m/s with 1 ms activation delay and 10 μs jitter in its timing performance. The shutter design is simple, easy to replicate, and highly reliable, showing no failure or degradation in performance over more than 10⁸ cycles
Fast and Highly Sensitive Ionic Polymer Gated WS$_2$-Graphene
  Photodetectors

The combination of graphene with semiconductor materials in heterostructure
photodetectors, has enabled amplified detection of femtowatt light signals
using micron-scale electronic devices. Presently, the speed of such detectors
is limited by long-lived charge traps and impractical strategies, e.g. the use
of large gate voltage pulses, have been employed to achieve bandwidths suitable
for applications, such as video-frame-rate imaging. Here, we report atomically
thin graphene-WS$_2$ heterostructure photodetectors encapsulated in an ionic
polymer, which are uniquely able to operate at bandwidths up to 1.5 kHz, whilst
maintaining internal gain as large as $10^6$. Highly mobile ions and a
nanometre scale Debye length of the ionic polymer are used to screen charge
traps and tune the Fermi level of graphene over an unprecedented range at the
interface with WS$_2$. We observe a responsivity $R=10^6$ A W$^{-1}$ and
detectivity $D^*=3.8\times10^{11}$ Jones, approaching that of single photon
counters. The combination of both high responsivity and fast response times
makes these photodetectors suitable for video-frame-rate imaging applications.Comment: 10 pages, 4 figures. To appear in Advanced Material
Time resolved multi mass ion imaging  Femtosecond UV VUV pump probe spectroscopy with the PImMS camera

The Pixel Imaging Mass Spectrometry  PImMS  camera allows for 3D charged particle imaging measurements, in which the particle time of flight is recorded along with  x, y  position. Coupling the PImMS camera to an ultrafast pump probe velocity map imaging spectroscopy apparatus therefore provides a route to time resolved multi mass ion imaging, with both high count rates and large dynamic range, thus allowing for rapid measurements of complex photofragmentation dynamics. Furthermore, the use of vacuum ultraviolet wavelengths for the probe pulse allows for an enhanced observation window for the study of excited state molecular dynamics in small polyatomic molecules having relatively high ionization potentials. Herein, preliminary time resolved multi mass imaging results from C2F3I photolysis are presented. The experiments utilized femtosecond VUV and UV  160.8 nm and 267 nm  pump and probe laser pulses in order to demonstrate and explore this new time resolved experimental ion imaging configuration. The data indicate the depth and power of this measurement modality, with a range of photofragments readily observed, and many indications of complex underlying wavepacket dynamics on the excited state s  prepare
Measurement of electrons from beauty-hadron decays in p-Pb collisions at √sNN = 5:02 TeV and Pb-Pb collisions at √sNN = 2:76 TeV

The production of beauty hadrons was measured via semi-leptonic decays at mid-rapidity with the ALICE detector at the LHC in the transverse momentum interval 1<pT< 8 GeV/c in minimum-bias p-Pb collisions at sNN−−−√=5.02 TeV and in 1.3 < pT< 8 GeV/c in the 20% most central Pb-Pb collisions at sNN−−−√=2.76 TeV. The pp reference spectra at sNN−−−√=5.02 TeV and s√=2.76 TeV, needed for the calculation of the nuclear modification factors RpPb and RPbPb, were obtained by a pQCD-driven scaling of the cross section of electrons from beauty-hadron decays measured at s√=7 TeV. In the pT interval 3 < pT< 8 GeV/c, a suppression of the yield of electrons from beauty-hadron decays is observed in Pb-Pb compared to pp collisions. Towards lower pT, the RPbPb values increase with large systematic uncertainties. The RpPb is consistent with unity within systematic uncertainties and is well described by theoretical calculations that include cold nuclear matter effects in p-Pb collisions. The measured RpPb and these calculations indicate that cold nuclear matter effects are small at high transverse momentum also in Pb-Pb collisions. Therefore, the observed reduction of RPbPb below unity at high pT may be ascribed to an effect of the hot and dense medium formed in Pb-Pb collisions
Search for new physics in events with photons, jets, and missing transverse energy in pp collisions at √s =7 TeV

A search for physics beyond the standard model involving events with one or more photons, jets, and missing transverse energy has been performed by the CMS experiment. The data sample corresponds to an integrated luminosity of 4.93 fb-1 of proton-proton collisions at √s =7 TeV, produced at the Large Hadron Collider. No excess of events with large missing transverse energy is observed beyond expectations from standard model processes, and upper limits on the signal production cross sections for new physics processes are set at the 95% confidence level. The results of this search are interpreted in the context of three models of new physics: a general model of gauge-mediated supersymmetry breaking, Simplified Models, and a theory involving universal extra dimensions. In the absence of evidence for new physics, exclusion regions are derived in the parameter spaces of the respective models.[Figure not available: see fulltext.] © 2013 CERN for the benefit of the CMS collaboration.The Scientific and Technical Research Council of Turkey, and Turkish Atomic Energy Authorit
