Jet-like correlations with neutral pion triggers in pp and central Pb–Pb collisions at 2.76 TeV

We present measurements of two-particle correlations with neutral pion trigger particles of transverse momenta View the MathML source8<pTtrig<16 GeV/c and associated charged particles of View the MathML source0.5<pTassoc<10 GeV/c versus the azimuthal angle difference Δφ   at midrapidity in pp and central Pb–Pb collisions at View the MathML sourcesNN=2.76 TeV with ALICE. The new measurements exploit associated charged hadrons down to 0.5 GeV/c0.5 GeV/c, which significantly extends our previous measurement that only used charged hadrons above 3 GeV/c3 GeV/c. After subtracting the contributions of the flow background, v2v2 to v5v5, the per-trigger yields are extracted for |Δφ|<0.7|Δφ|<0.7 on the near and for |Δφ−π|<1.1|Δφ−π|<1.1 on the away side. The ratio of per-trigger yields in Pb–Pb to those in pp collisions, IAAIAA, is measured on the near and away side for the 0–10%0–10% most central Pb–Pb collisions. On the away side, the per-trigger yields in Pb–Pb are strongly suppressed to the level of IAA≈0.6IAA≈0.6 for View the MathML sourcepTassoc>3 GeV/c, while with decreasing momenta an enhancement develops reaching about 5 at low View the MathML sourcepTassoc. On the near side, an enhancement of IAAIAA between 1.2 at the highest to 1.8 at the lowest View the MathML sourcepTassoc is observed. The data are compared to parton-energy-loss predictions of the JEWEL and AMPT event generators, as well as to a perturbative QCD calculation with medium-modified fragmentation functions. All calculations qualitatively describe the away-side suppression at high View the MathML sourcepTassoc. Only AMPT captures the enhancement at low View the MathML sourcepTassoc, both on the near and away side. However, it also underpredicts IAAIAA above 5 GeV/c5 GeV/c, in particular on the near-side
Correlation between Zn vacancies and photoluminescence emission in ZnO films

Photoluminescence and positron annihilation spectroscopy have been used to characterize and identify vacancy-type defects produced in ZnO films grown on sapphire by metal-organic chemical-vapor deposition. The photoluminescence of the samples in the near band edge region has been studied, paying particular attention to the emission at 370.5nm (3.346eV). This emission has been correlated to the concentration of Zn vacancies in the films, which has been determined by positron annihilation spectroscopy.Peer reviewe
Integrating radar and laser-based remote sensing techniques for monitoring structural deformation of archaeological monuments

AbstractGround-Based Synthetic Aperture Radar Interferometry (GBInSAR) and Terrestrial Laser Scanning (TLS) were purposely integrated to obtain 3D interferometric radar point clouds to facilitate the spatial interpretation of displacements affecting archaeological monuments. The paper describes the procedure to implement this integrated approach in the real-world situations of surveillance of archaeological and built heritage. Targeted tests were carried out on the case study of the Domus Tiberiana sited along the northern side of the Palatino Hill in the central archaeological area of Rome, Italy, and displacements of the monument were monitored over almost one year of acquisition. The GBInSAR – TLS integration provided updated information about the condition of the archaeological structures in relation to their history of instability mechanisms, and did not highlighted a general worsening for the stability of the entire monument. Point-wise and prompt detection of displacement anomalies and/or sudden changes in displacement trends proved the suitability of the method to support early warning procedures, also to evaluate effects on the masonry due to human activities
Predictors of subjective health status 10years post-PCI

AbstractBackgroundSubjective health status is an increasingly important parameter to assess the effect of percutaneous coronary intervention (PCI) in clinical practice.Aim of this study was to determine medical and psychosocial predictors of poor subjective health status over a 10years' post-PCI period.MethodsWe included a series of consecutive PCI patients (n=573) as part of the RESEARCH registry, a Dutch single-center retrospective cohort study.ResultsThese patients completed the 36-item Short-Form Health Survey (SF-36) at baseline and 10years post-PCI. We found 6 predictors of poor subjective health status 10years post-PCI: SF-36 at baseline, age, previous PCI, obesity, acute myocardial infarction as indication for PCI, and diabetes mellitus (arranged from most to least numbers of sub domains).ConclusionsSF-36 scores at baseline, age, and previous PCI were significant predictors of subjective health status 10years post-PCI. Specifically, the SF-36 score at baseline was an important predictor. Thus assessment of subjective health status at baseline is useful as an indicator to predict long-term subjective health status. Subjective health status becomes better by optimal medical treatment, cardiac rehabilitation and psychosocial support. This is the first study determining predictors of subjective health status 10years post-PCI
A Simple Molecular Complex Mediates Widespread BMP-Induced Repression during Drosophila Development

AbstractThe spatial and temporal control of gene expression during the development of multicellular organisms is regulated to a large degree by cell-cell signaling. We have uncovered a simple mechanism through which Dpp, a TGFβ/BMP superfamily member in Drosophila, represses many key developmental genes in different tissues. A short DNA sequence, a Dpp-dependent silencer element, is sufficient to confer repression of gene transcription upon Dpp receptor activation and nuclear translocation of Mad and Medea. Transcriptional repression does not require the cooperative action of cell type-specific transcription factors but relies solely on the capacity of the silencer element to interact with Mad and Medea and to subsequently recruit the zinc finger-containing repressor protein Schnurri. Our findings demonstrate how the Dpp pathway can repress key targets in a simple and tissue-unrestricted manner in vivo and hence provide a paradigm for the inherent capacity of a signaling system to repress transcription upon pathway activation
Gauged Two Higgs Doublet Model confronts the LHC 750 GeV diphoton anomaly

AbstractIn light of the recent 750 GeV diphoton anomaly observed at the LHC, we study the possibility of accommodating the deviation from the standard model prediction based on the recently proposed Gauged Two Higgs Doublet Model. The model embeds two Higgs doublets into a doublet of a non-abelian gauge group SU(2)H, while the standard model SU(2)L right-handed fermion singlets are paired up with new heavy fermions to form SU(2)H doublets, and SU(2)L left-handed fermion doublets are singlets under SU(2)H. An SU(2)H scalar doublet, which provides masses to the new heavy fermions as well as the SU(2)H gauge bosons, can be produced via gluon fusion and subsequently decays into two photons with the new fermions circulating the triangle loops to account for the deviation from the standard model prediction

Randomized Trial to Evaluate Tandospirone in Geographic Atrophy Secondary to Age-Related Macular Degeneration: The GATE Study

PurposeTo determine the safety and efficacy of AL-8309B (tandospirone) in the management of patients with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) and obtain standardized data on GA lesion growth progression.DesignProspective, controlled, double-masked, randomized, multicenter phase 3 clinical trial.Methodssetting: Forty-eight clinical sites. patients: Patients with GA associated with AMD were enrolled. All patients were followed for a minimum of 30 months, and up to 36 months. intervention procedures: Patients were randomized (1:1:1) to receive AL-8309B ophthalmic solution 1.0%, 1.75%, or vehicle, administered as a twice-daily topical ocular drop. main outcome measures: The primary efficacy endpoint was mean annualized lesion enlargement from baseline as assessed with fundus autofluorescence (FAF) imaging.ResultsA total of 768 eyes of 768 patients were enrolled and treated with AL-8309B 1.0% (n = 250), AL-8309B 1.75% (n = 258), or vehicle (n = 260). An increase in mean lesion size was observed in both the AL-8309B and vehicle treatment groups, and growth rates were similar in all treatment groups. Annualized lesion growth rates were 1.73, 1.76, and 1.71 mm2 for AL-8309B 1.0%, AL-8309B 1.75%, and vehicle, respectively.ConclusionsAL-8309B 1.0% and 1.75% did not affect lesion growth in eyes with GA secondary to AMD. There were no clinically relevant safety issues identified for AL-8309B. The large natural history dataset from this study is a valuable repository for future comparisons
Admissible submonoids of Artin–Tits monoids

AbstractWe show the analogue of Mühlherr’s [B. Mühlherr, Coxeter groups in Coxeter groups, in: Finite Geometry and Combinatorics, Cambridge University Press, 1993, pp. 277–287] for Artin–Tits monoids and for Artin–Tits groups of spherical type. That is, the submonoid (resp. subgroup) of an Artin–Tits monoid (resp. group of spherical type) induced by an admissible partition of the Coxeter graph is an Artin–Tits monoid (resp. group).This generalizes and unifies the situation of the submonoid (resp. subgroup) of fixed elements of an Artin–Tits monoid (resp. group of spherical type) under the action of graph automorphisms, and the notion of LCM-homomorphisms defined by Crisp in [J. Crisp, Injective maps between Artin groups, in: Geom. Group Theory Down Under (Canberra 1996), de Gruyter, Berlin, 1999, pp. 119–137] and generalized by Godelle in [E. Godelle, Morphismes injectifs entre groupes d’Artin-Tits, Algebr. Geom. Topol. 2 (2002) 519–536].We then complete the classification of the admissible partitions for which the Coxeter graphs involved have no infinite label, started by Mühlherr in [B. Mühlherr, Some contributions to the theory of buildings based on the gate property, Dissertation, Tübingen, 1994]. This leads us to the classification of Crisp’s LCM-homomorphisms
Adolescents with asthma: Consequences of transition from paediatric to adult healthcare

SummaryPurposeA prospective follow-up of adolescents with asthma designed to identify risk factors for deterioration during and after transfer from paediatric to adult healthcare.MethodsAdolescents (n=150) with asthma being transferred from paediatric to adult healthcare were recruited consecutively and those with mild/moderate asthma assigned randomly to primary care or specialized care at an adult asthma clinic. Tests of pulmonary function, bronchial responsiveness and working capacity and skin prick tests were performed at the time of entry into the study and two and/or five years later.ResultsInitially, 88.7% of the subjects demonstrated at least one positive skin prick test. During the five-year follow-up, FEV1 improved, while FEV1/FVC remained unchanged. Bronchial hyperresponsiveness was present in 71% of the subjects at the time of inclusion and 59% five years later, while 20 developed hyperresponsiveness during this period. Poor adherence to treatment, female gender and inhalation of steroids exerted negative impacts on logPD20. The risk for persistence of bronchial hyperresponsiveness was elevated by poor adherence and attenuated by regular exercise. The decline observed in working capacity demonstrated no correlation to the risk factors examined. Subjects with mild/moderate asthma who received primary or specialized care exhibited similar pulmonary function, responses to a histamine challenge and working capacities.ConclusionsDuring a five-year follow-up of asthmatic adolescents leaving paediatric care, pulmonary function rarely deteriorated, but bronchial hyperresponsiveness persisted. Female gender and poor adherence to treatment exerted negative impact on bronchial hyperresponsiveness. Mild/moderate asthma was managed equally effectively with primary or specialized care
Echinocyte Shapes: Bending, Stretching, and Shear Determine Spicule Shape and Spacing

AbstractWe study the shapes of human red blood cells using continuum mechanics. In particular, we model the crenated, echinocytic shapes and show how they may arise from a competition between the bending energy of the plasma membrane and the stretching/shear elastic energies of the membrane skeleton. In contrast to earlier work, we calculate spicule shapes exactly by solving the equations of continuum mechanics subject to appropriate boundary conditions. A simple scaling analysis of this competition reveals an elastic length Λel, which sets the length scale for the spicules and is, thus, related to the number of spicules experimentally observed on the fully developed echinocyte
Hypoxia-Independent Angiogenesis in Adipose Tissues during Cold Acclimation

SummaryThe molecular mechanisms of angiogenesis in relation to adipose tissue metabolism remain poorly understood. Here, we show that exposure of mice to cold led to activation of angiogenesis in both white and brown adipose tissues. In the inguinal depot, cold exposure resulted in elevated expression levels of brown-fat-associated proteins, including uncoupling protein-1 (UCP1) and PGC-1α. Proangiogenic factors such as VEGF were upregulated, and endogenous angiogenesis inhibitors, including thrombospondin, were downregulated. In wild-type mice, the adipose tissues became hypoxic during cold exposure; in UCP1−/− mice, hypoxia did not occur, but, remarkably, the augmented angiogenesis was unaltered and was thus hypoxia independent. Intriguingly, VEGFR2 blockage abolished the cold-induced angiogenesis and significantly impaired nonshivering thermogenesis capacity. Unexpectedly, VEGFR1 blockage resulted in the opposite effects: increased adipose vascularity and nonshivering thermogenesis capacity. Our findings have conceptual implications concerning application of angiogenesis modulators for treatment of obesity and metabolic disorders
Spatial Diffusion and Spatial Statistics: Revisting Hägerstrand's Study of Innovation Diffusion

AbstractTorsten Hägerstrand's 1953 study of innovation diffusion [1] was pathbreaking in many ways. It was based on an explicit micro-model of information spread, and on Monte Carlo simulation of the hypothesised spatial process. Using the original aggregated data and Hope-type tests of the ability of the simulations to capture the observed adoptions, (author?) [2] and (author?) [3] and others found problems. This study attempts to examine the extent to which we may be able to “do better” with a range of approaches drawn from spatial statistics, including using a SAR lattice model, geostatistical modelling, Moran eigenvectors, and other approaches
Production of doubly charmed tetraquarks with exotic color configurations in electron–positron collisions

AbstractStructure and production of doubly charmed tetraquarks Tcc (ccu¯d¯) are studied from the viewpoint of color configurations. Based on the diquark correlation, the tetraquark Tcc with I(JP)=0(1+) is considered to be stable against strong decay. We discuss that the mixing probability of color antitriplet and sextet cc components in Tcc is suppressed by 1/mc2, so the two configurations are separately realized in the heavy quark limit. Utilizing the nonrelativistic QCD framework, we evaluate the production cross sections of Tcc in electron–positron collisions. The momentum dependence of the cross section of color antitriplet is found to be different from that of sextet, which can be used to discriminate the color structure of the Tcc states in experimental measurements
Ultradispersed Hydrocarbon Synthesis Catalyst from CO and H2 Based on Electroexplosion of Iron Powder

AbstractThe structure and properties of disperse particles of electroexplosive iron-based powder are studied with a laser diffraction method, transmission electron microscopy analysis and X-ray photography. The catalytic activity of ultradispersed iron powders in the synthesis of hydrocarbons from CO and H2 by Fischer – Tropsch method is measured by concentration of the paramagnetic particles with electron paramagnetic resonance. In the laboratory of catalytic plant, hydrocarbons are synthesized at various feed mixture. Composition of liquid and gas products of synthesis are studied. Under explosion conditions, the electric wires of iron powders can be prepared with the specified properties (phase composition, particle size and structure). Powder of Fe (CO) can be used as a catalyst of the Fischer – Tropsch synthesis without reduction since during electrical explosion in an atmosphere of carbon monoxide generated phase structure needed to activate hydrocarbon synthesis reaction of a mixture of CO and H2
The functional foetal brain: A systematic preview of methodological factors in reporting foetal visual and auditory capacity

ABSTRACTDue to technological advancements in functional brain imaging, foetal brain responses to visual and auditory stimuli is a growing area of research despite being relatively small with much variation between research laboratories. A number of inconsistencies between studies are, nonetheless, present in the literature. This article aims to explore the potential contribution of methodological factors to variation in reports of foetal neural responses to external stimuli. Some of the variation in reports can be explained by methodological differences in aspects of study design, such as brightness and wavelength of light source. In contrast to visual foetal processing, auditory foetal processing has been more frequently investigated and findings are more consistent between different studies. This is an early preview of an emerging field with many articles reporting small sample sizes with techniques that are yet to be replicated. We suggest areas for improvement for the field as a whole, such as the standardisation of stimulus delivery and a more detailed reporting of methods and results. This will improve our understanding of foetal functional response to light and sound. We suggest that enhanced technology will allow for a more reliable description of the developmental trajectory of foetal processing of light stimuli
The Rényi–Ulam pathological liar game with a fixed number of lies

AbstractThe q-round Rényi–Ulam pathological liar game with k lies on the set [n]≔{1,…,n} is a 2-player perfect information zero sum game. In each round Paul chooses a subset A⊆[n] and Carole either assigns 1 lie to each element of A or to each element of [n]⧹A. Paul wins if after q rounds there is at least one element with k or fewer lies. The game is dual to the original Rényi–Ulam liar game for which the winning condition is that at most one element has k or fewer lies. Define Fk*(q) to be the minimum n such that Paul can win the q-round pathological liar game with k lies and initial set [n]. For fixed k we prove that Fk*(q) is within an absolute constant (depending only on k) of the sphere bound, 2q/q⩽k; this is already known to hold for the original Rényi–Ulam liar game due to a result of J.Spencer
Azimuthal anisotropy of charged jet production in sNN=2.76 TeV Pb–Pb collisions

AbstractWe present measurements of the azimuthal dependence of charged jet production in central and semi-central sNN=2.76 TeV Pb–Pb collisions with respect to the second harmonic event plane, quantified as v2ch jet. Jet finding is performed employing the anti-kT algorithm with a resolution parameter R=0.2 using charged tracks from the ALICE tracking system. The contribution of the azimuthal anisotropy of the underlying event is taken into account event-by-event. The remaining (statistical) region-to-region fluctuations are removed on an ensemble basis by unfolding the jet spectra for different event plane orientations independently. Significant non-zero v2ch jet is observed in semi-central collisions (30–50% centrality) for 20<pTch jet<90 GeV/c. The azimuthal dependence of the charged jet production is similar to the dependence observed for jets comprising both charged and neutral fragments, and compatible with measurements of the v2 of single charged particles at high pT. Good agreement between the data and predictions from JEWEL, an event generator simulating parton shower evolution in the presence of a dense QCD medium, is found in semi-central collisions
Spectral reflectance data of a high temperature stable solar selective coating based on MoSi2–Si3N4

AbstractData of optical performance, thermal stability and ageing are given for solar selective coatings (SSC) based on a novel MoSi2–Si3N4 absorbing composite. SSC have been prepared as multilayer stacks formed by silver as metallic infrared reflector, a double layer composite and an antireflective layer (doi: 10.1016/j.solmat.2016.04.001 [1]). Spectroscopic reflectance data corresponding to the optical performance of samples after moderate vacuum annealing at temperatures up to 600°C and after ageing test of more than 200h with several heating–cooling cycles are shown here
The pretzelosity TMD and quark orbital angular momentum

AbstractWe study the connection between the quark orbital angular momentum and the pretzelosity transverse-momentum dependent parton distribution function. We discuss the origin of this relation in quark models, identifying as key ingredient for its validity the assumption of spherical symmetry for the nucleon in its rest frame. Finally we show that the individual quark contributions to the orbital angular momentum obtained from this relation cannot be interpreted as the intrinsic contributions, but include the contribution from the transverse centre of momentum which cancels out only in the total orbital angular momentum
Search for pair production of third-generation scalar leptoquarks and top squarks in proton–proton collisions at s=8 TeV

AbstractA search for pair production of third-generation scalar leptoquarks and supersymmetric top quark partners, top squarks, in final states involving tau leptons and bottom quarks is presented. The search uses events from a data sample of proton–proton collisions corresponding to an integrated luminosity of 19.7 fb−1, collected with the CMS detector at the LHC with s=8 TeV. The number of observed events is found to be in agreement with the expected standard model background. Third-generation scalar leptoquarks with masses below 740 GeV are excluded at 95% confidence level, assuming a 100% branching fraction for the leptoquark decay to a tau lepton and a bottom quark. In addition, this mass limit applies directly to top squarks decaying via an R-parity violating coupling λ333′. The search also considers a similar signature from top squarks undergoing a chargino-mediated decay involving the R-parity violating coupling λ3jk′. Each top squark decays to a tau lepton, a bottom quark, and two light quarks. Top squarks in this model with masses below 580 GeV are excluded at 95% confidence level. The constraint on the leptoquark mass is the most stringent to date, and this is the first search for top squarks decaying via λ3jk′
