Abstract

New results for the double spin asymmetry A(1)(p) and the proton longitudinal spin structure function g(1)(p) are presented. They were obtained by the COMPASS Collaboration using polarised 200 GeV muons scattered off a longitudinally polarised NH3 target. The data were collected in 2011 and complement those recorded in 2007 at 160 GeV, in particular at lower values of x. They improve the statistical precision of g(1)(p)(x) by about a factor of two in the region x less than or similar to 0.02. A next-to-leading order QCD fit to the g(1) world data is performed. It leads to a new determination of the quark spin contribution to the nucleon spin, Delta Sigma, ranging from 0.26 to 0.36, and to a re-evaluation of the first moment of g(1)(p). The uncertainty of Delta Sigma is mostly due to the large uncertainty in the present determinations of the gluon helicity distribution. A new evaluation of the Bjorken sum rule based on the COMPASS results for the non-singlet structure function g(1)(NS) (x, Q(2)) yields as ratio of the axial and vector coupling constants vertical bar gA/gV vertical bar = 1.22 +/- 0.05 (stat.) +/- 0.10 (syst.), which validates the sum rule to an accuracy of about 9%.

Abstract

Smoking habit at the time of surgery is associated with higher perioperative complications and mortality across different types of surgeries. In recent years, several studies have attempted to explore the influence of smoking on perioperative outcomes following radical cystectomy (RC) for urothelial bladder cancer (UBC) with contradictory results.

Abstract

The COMPASS collaboration has collected the currently largest data set on diffractively produced pi(-) pi(-) pi(+) final states using a negative pion beam of 190 GeV/c momentum impinging on a stationary proton target. This data set allows for a systematic partial-wave analysis in 100 bins of three-pion mass, 0.5 < m(3 pi) < 2.5 GeV/c(2), and in 11 bins of the reduced four-momentum transfer squared, 0.1 < t' < 1.0 (GeV/c)(2). This two-dimensional analysis offers sensitivity to genuine one-step resonance production, i.e. the production of a state followed by its decay, as well as to more complex dynamical effects in nonresonant 3 pi production. In this paper, we present detailed studies on selected 3p partial waves with J(PC) = 0(-+) ,1(++) ,2(-+) ,2(++) ,and 4(++). In these waves, we observe the well-known groundstate mesons as well as a new narrow axial-vector meson a(1)(1420) decaying into f(0) (980)pi. In addition, we present the results of a novel method to extract the amplitude of the pi(-)pi(+) subsystem with I(G)J(PC) = 0(+)0(++) in various partial waves from the pi(-)pi(-)pi(+) data. Evidence is found for correlation of the f (0)(980) and f(0)(1500) appearing as intermediate pi(-)pi(+) isobars in the decay of the known pi(1800) and pi(2)(1880).

Abstract

Proton transverse-spin azimuthal asymmetries are extracted from the COMPASS 2010 semi-inclusive hadron measurements in deep inelastic muon-nucleon scattering in those four regions of the photon virtuality $Q^2$, which correspond to the four regions of the di-muon mass $\sqrt{Q^2}$ used in the ongoing analysis of the COMPASS Drell-Yan measurements. This allows for a future direct comparison of the nucleon transverse-momentum-dependent parton distribution functions extracted from these two alternative measurements. Various two-dimensional kinematic dependences are presented for the azimuthal asymmetries induced by the Sivers transverse-momentum-dependent parton distribution function. The integrated Sivers asymmetries are found to be positive with an accuracy that appears to be sufficient to test the sign change of the Sivers function predicted by Quantum Chromodynamics., 13 pages, 6 figures

Abstract

The Sivers function describes the correlation between the transverse spin of a nucleon and the transverse motion of its partons. It was extracted from measurements of the azimuthal asymmetry of hadrons produced in semi-inclusive deep inelastic scattering of leptons off transversely polarised nucleon targets, and it turned out to be non-zero for quarks. In this letter the evaluation of the Sivers asymmetry for gluons in the same process is presented. The analysis method is based on a Monte Carlo simulation that includes three hard processes: photon-gluon fusion, QCD Compton scattering and leading-order virtual-photon absorption process. The Sivers asymmetries of the three processes are simultaneously extracted using the LEPTO event generator and a neural network approach. The method is applied to samples of events containing at least two hadrons with large transverse momentum from the COMPASS data taken with a 160 GeV/$c$ muon beam scattered off transversely polarised deuterons and protons. With a significance of more than two standard deviations a negative value is obtained for the gluon Sivers asymmetry. The result of a similar analysis for a Collins-like asymmetry for gluons is consistent with zero., Comment: 18 pages, 8 figures

Abstract

Multiplicities of charged pions and charged hadrons produced in deep-inelastic scattering were measured in three-dimensional bins of the Bjorken scaling variable x , the relative virtual-photon energy y and the relative hadron energy z . Data were obtained by the COMPASS Collaboration using a 160GeV muon beam and an isoscalar target ( 6 LiD). They cover the kinematic domain in the photon virtuality Q2>1(GeV/c)2 , 0.004 1(GeV/c$)^2$, $0.004 < x < 0.4$, $0.2 < z < 0.85$ and $0.1 < y < 0.7$. In addition, a leading-order pQCD analysis was performed using the pion multiplicity results to extract quark fragmentation functions.

Abstract

Precise measurements of charged-kaon multiplicities in deep inelastic scattering were performed. The results are presented in three-dimensional bins of the Bjorken scaling variable x, the relative virtual-photon energy y, and the fraction z of the virtual-photon energy carried by the produced hadron. The data were obtained by the COMPASS Collaboration by scattering 160 GeV muons off an isoscalar 6 LiD target. They cover the kinematic domain 1 (GeV/c)2 < Q2 < 60 (GeV/c)^2 in the photon virtuality, 0.004 < x < 0.4, 0.1 < y < 0.7, 0.20 < z < 0.85, and W > 5 GeV/c^2 in the invariant mass of the hadronic system. The results from the sum of the z-integrated K+ and K- multiplicities at high x point to a value of the non-strange quark fragmentation function larger than obtained by the earlier DSS fit., 10 pages, 9 figures

215. Monitoring vegetationsökologischer Phänomene mit Hilfe von Vegetationsindizes basierend auf Massendaten

Author

Kremser, Felix and Kremser, Felix

Abstract

Als Datengrundlage für die Arbeit dienen Satellitenbilder von Satelliten aus der Landsat Mission, welche seit den 1970er Jahren zur Verfügung stehen. Es werden Zeitreihenanalysen des NDVI (Normalized Differenced Vegetation Index) für naturschutzrelevante Testgebiete in Österreich durchgeführt. Die Zeitreihenanalysen reichen bis zum Jahr 2000 zurück. Ausschlaggebend für die Analyse ist, dass Satellitenbildszenen über einen möglichst langen Zeitraum verfügbar sind. Dies ist wichtig um den Wandel der Bewirtschaftungsformen im landwirtschaftlichen Bereich bzw. Rückschlüsse auf langfristige Veränderungen von naturschutzrelevanten Flächen dokumentieren zu können. *****Satellite images from the Landsat mission, which are available since 1970, are used to calculate timelines of the NDVI (Normalized Differenced Vegetation Index) for relevant succession zones in austria. The timelines date back to the year 2000. Important for the analysis is the availability of satellite image scenes over a the whole period. This is important for the monitoring of the forms of succession in the agricultural sector and to retrieve conclusions on long-term changes of areas relevant to nature conservation.

Abstract

We measured the longitudinal double spin asymmetries $A_{LL}$ for single hadron muo-production off protons and deuterons at photon virtuality $Q^2$ < 1(GeV/$\it c$)$^2$ for transverse hadron momenta $p_T$ in the range 0.7 GeV/$\it c$ to 4 GeV/$\it c$ . They were determined using COMPASS data taken with a polarised muon beam of 160 GeV/$\it c$ or 200 GeV/$\it c$ impinging on polarised $\mathrm{{}^6LiD}$ or $\mathrm{NH_3}$ targets. The experimental asymmetries are compared to next-to-leading order pQCD calculations, and are sensitive to the gluon polarisation $\Delta G$ inside the nucleon in the range of the nucleon momentum fraction carried by gluons $0.05 < x_g < 0.2$. We measured the longitudinal double spin asymmetries ALL for single hadron muoproduction off protons and deuterons at photon virtuality Q2

Abstract

AbstractPurpose:To assess the prognostic significance of the nuclear receptor binding SET protein 2 (NSD2), a co-activator of the NFkB-pathway, on tumour progression in patients with advanced prostate cancer (PCa).Methods:We retrospectively assessed NSD2 expression in 53 patients with metastatic and castration-resistant PCa. Immunohistochemical staining for NSD2 was carried out on specimen obtained from palliative resection of the prostate. Univariable and multivariable analyses were performed to assess the association between NSD2 expression and PCa progression.Results:Of the 53 patients, 41 had castration-resistant PCa and 48 men had metastases at time of tissue acquisition. NSD2 expression was increased in tumour specimen from 42 patients (79.2%). In univariable Cox regression analyses, NSD2 expression was associated with PSA progression, progression on imaging and overall survival (p = 0.04, respectively). In multivariable analyses, NSD2 expression did not retain its association with these endpoints.Conclusions:NSD2 expression is abnormal in almost 80% of patients with advanced PCa. Expression levels of this epigenetic regulator are easily detected by immunohistochemistry while this biomarker exhibited prognostic value for PCa progression and death in univariable analysis. Further studies on NSD2 involvement in PCa proliferation, progression, metastasis and resistance mechanisms are needed.

Abstract

The diagnostic potential of multimodal MRI approaches to discriminate among progressive supranuclear palsy (PSP), Parkinson variant of multiple system atrophy (MSA-P) and Parkinson’s disease (PD) has not been well investigated. To identify disease-specific neurodegenerative patterns and evaluate the diagnostic accuracy of dedicated MRI, iron concentration (R2*), microstructural integrity (mean diffusivity; MD and fractional anisotropy; FA) as well as volumes were analyzed in patients with PSP, MSA-P and PD. 3T MRI of 18 PSP and 16 MSA-P patients were compared with 16 PD patients matched for age and disease duration as well as 21 healthy controls. Statistical parametric mapping (SPM) was applied to objectively identify focal MRI changes throughout the whole-brain. Following dimensionality reduction of significant and multiple comparison-corrected SPM clusters through principal component analysis (PCA), stepwise receiver-operating characteristic curve analysis (ROC) was applied to determine the diagnostic potential of multimodal MRI parameters. PCA revealed two components involving multiple regions identified from SPM analysis. The first component was primarily composed of the mean MD value of the thalamus and the mean MD and FA values of the dentatorubrothalamic tract and the corpus callosum. The second component mainly consisted of mean MD and FA values of the middle cerebellar peduncle. ROC analysis showed 92% of PSP patients were differentiated correctly from MSA-P and PD and 80% of MSA-P patients could be distinguished from PD. Multimodal MRI improved the detection of disease-specific neurodegenerative patterns in PSP and MSA-P and highlights its potential to improve the diagnostic accuracy of atypical parkinsonian disorders.

Abstract

Background A number of clinical reasoning models, including hypothetico-deductive, pattern recognition and narrative reasoning have been identified in both novice and experienced medical, nursing and allied health professionals. The aim of this project was to explore clinical reasoning in osteopathy from the perspectives of both experienced practitioners and novice practitioners. Methods Data were collected via semi-structured interviews that encouraged practitioners to reflect on the clinical reasoning processes they used in response to two case studies. Interviews were transcribed and analysed to identify key themes. Results Two themes emerged: (1) that experienced and novice osteopaths demonstrated different approaches to clinical reasoning, and (2) that experiential findings (e.g. from observation and palpatory findings derived from having direct contact with the patient) were integral to clinical reasoning in osteopathy. Conclusion The results of this study suggest that clinical reasoning in osteopathy is similar to that of other health professions in that deep understanding of clinical applications and clinical experience were key factors in developing sophisticated clinical reasoning processes. However, clinical reasoning in osteopathy, unlike many other health professions, relies on experiential findings resulting from direct observation and palpatory contact with the patient. Clinical reasoning that relies on subjective experiential findings requires further investigation. [ABSTRACT FROM AUTHOR]

Abstract

State-of-the-art experiments in nuclear and high-energy physics typically operate with high-luminosity beams which leads to high event rates and large amounts of data from the detectors. The background-induced occupancy of the detector channels can be quite high; therefore it is important to have sophisticated trigger subsystems which process the data in realtime to generate trigger objects for the global trigger decision. In this work we present a FPGA based low-latency trigger processor for the COMPASS-II experiment.
