These final states provide sensitivity to the heavy-flavour content of the proton and aspects related to the modelling of heavy-flavour quarks in perturbative QCD. The measurement uses proton-proton collision data at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector at the LHC in 2012 corresponding to an integrated luminosity of up to 20.2 fb-1 . The differential cross sections are measured for each jet flavour with respect to the transverse energy of the leading photon in two photon pseudorapidity regions: |η γ | < 1.37 and 1.56 < |η γ | < 2.37. The measurement covers photon transverse energies 25 < Eγ T < 400 GeV and 25 < Eγ T < 350 GeV respectively for the two |η γ | regions. For each jet flavour, the ratio of the cross sections in the two |η γ | regions is also measured. The measurement is corrected for detector effects and compared to leading-order and next- to-leading-order perturbative QCD calculations, based on various treatments and assumptions about the heavy-flavour content of the proton. Overall, the predictions agree well with the measurement, but some deviations are observed at high photon transverse energies. The total uncertainty in the measurement ranges between 13\% and 66\%, while the central γ + b measurement exhibits the smallest uncertainty, ranging from 13\% to 27\%, which is comparable to the precision of the theoretical predictions.}, language = {en} } @article{OPUS4-22686, title = {Resolution of the ATLAS muon spectrometer monitored drift tubes in LHC Run 2}, series = {Journal of Instrumentation}, volume = {14}, journal = {Journal of Instrumentation}, organization = {The ATLAS Collaboration}, doi = {10.1088/1748-0221/14/09/P09011}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-226869}, pages = {1-34}, year = {2019}, abstract = {The momentum measurement capability of the ATLAS muon spectrometer relies fundamentally on the intrinsic single-hit spatial resolution of the monitored drift tube precision tracking chambers.

We investigated the long-term benefits and risks of NACT and the influence of tumour characteristics on outcome with a collaborative meta-analysis of individual patient data from relevant randomised trials. Methods We obtained information about prerandomisation tumour characteristics, clinical tumour response, surgery, recurrence, and mortality for 4756 women in ten randomised trials in early breast cancer that began before 2005 and compared NACT with the same chemotherapy given postoperatively. Primary outcomes were tumour response, extent of local therapy, local and distant recurrence, breast cancer death, and overall mortality. Analyses by intention-to-treat used standard regression (for response and frequency of breast-conserving therapy) and log-rank methods (for recurrence and mortality). Findings Patients entered the trials from 1983 to 2002 and median follow-up was 9 years (IQR 5-14), with the last follow-up in 2013. Most chemotherapy was anthracycline based (3838 [81\%] of 4756 women). More than two thirds (1349 [69\%] of 1947) of women allocated NACT had a complete or partial clinical response. Patients allocated NACT had an increased frequency of breast-conserving therapy (1504 [65\%] of 2320 treated with NACT vs 1135 [49\%] of 2318 treated with adjuvant chemotherapy). NACT was associated with more frequent local recurrence than was adjuvant chemotherapy: the 15 year local recurrence was 21.4\% for NACT versus 15.9\% for adjuvant chemotherapy (5.5\% increase [95\% CI 2.4-8.6]; rate ratio 1.37 [95\% CI 1.17-1.61]; p = 0.0001). No significant difference between NACT and adjuvant chemotherapy was noted for distant recurrence (15 year risk 38.2\% for NACT vs 38.0\% for adjuvant chemotherapy; rate ratio 1.02 [95\% CI 0.92-1.14]; p = 0.66), breast cancer mortality (34.4\% vs 33.7\%; 1.06 [0.95-1.18]; p = 0.31), or death from any cause (40.9\% vs 41.2\%; 1.04 [0.94-1.15]; p = 0.45). Interpretation Tumours downsized by NACT might have higher local recurrence after breast-conserving therapy than might tumours of the same dimensions in women who have not received NACT. Strategies to mitigate the increased local recurrence after breast-conserving therapy in tumours downsized by NACT should be considered-eg, careful tumour localisation, detailed pathological assessment, and appropriate radiotherapy.

Thanks to its geographical location on the Northern hemisphere, KM3NeT/ARCA can observe upgoing neutrinos from most of the Galactic Plane, including the Galactic Centre. Given its effective area and excellent pointing resolution, KM3NeT/ARCA will measure or significantly constrain the neutrino flux from potential astrophysical neutrino sources. At the same time, it will test flux predictions based on gamma-ray measurements and the assumption that the gamma-ray flux is of hadronic origin. Assuming this scenario, discovery potentials and sensitivities for a selected list of Galactic sources and to generic point sources with an E-2 spectrum are presented. These spectra are assumed to be time independent.

These platelet functions, referred to as thrombo-inflammation and immunothrombosis, have gained major attention in the COVID-19 pandemic, where patients develop an inflammatory disease state with severe and life-threatening thromboembolic complications. In the CRC/TR 240, a highly interdisciplinary team of basic, translational and clinical scientists explored these emerging roles of platelets with the aim to develop novel treatment concepts for cardiovascular disorders and beyond. We have i) unravelled mechanisms leading to life-threatening thromboembolic complica-tions following vaccination against SARS-CoV-2 with adenoviral vector-based vaccines, ii) identified unrecognised functions of platelet receptors and their regulation, offering new potential targets for pharmacological intervention and iii) developed new methodology to study the biology of megakar-yocytes (MKs), the precursor cells of platelets in the bone marrow, which lay the foundation for the modulation of platelet biogenesis and function. The projects of the CRC/TR 240 built on the unique expertise of our research network and focussed on the following complementary fields: (A) Cell bi-ology of megakaryocytes and platelets and (B) Platelets as regulators and effectors in disease. To achieve this aim, we followed a comprehensive approach starting out from in vitro systems and animal models to clinical research with large prospective patient cohorts and data-/biobanking.

Zoopoetics and Ecopoetics probes the multiple links between ecocriticism and animal studies, assessing the relations between animals, environments and poetics. While ecocriticism usually relies on a relational approach to explore phenomena related to the environment or ecology more broadly, animal studies tends to examine individual or species-specific aspects. As a consequence, ecocriticism concentrates on ecopoetical, animal studies on zoopoetical elements and modes of representation in literature (and the arts more generally). Bringing key concepts of ecocriticism and animal studies into dialogue, the volume explores new ways of thinking about and reading texts, animals, and environments - not as separate entities but as part of the same collective.}, language = {en} } @inproceedings{OPUS4-25117, title = {Zur Geschichte der Fach- und Wissenschaftssprachen.

The measurement was performed using 0.14 nb\(^{-1}\) of data recorded in 2011. The production of correlated jet pairs was quantified using the rate, R\(_{ΔR}\), of "neighbouring" jets that accompany "test" jets within a given range of angular distance, ΔR , in the pseudorapidity-azimuthal angle plane. The jets were measured in the ATLAS calorimeter and were reconstructed using the anti-k\(_t\) algorithm with radius parameters d=0.2, 0.3, and 0.4. R\(_{ΔR}\) was measured in different Pb+Pb collision centrality bins, characterized by the total transverse energy measured in the forward calorimeters. A centrality dependence of R\(_{ΔR}\) is observed for all three jet radii with R\(_{ΔR}\) found to be lower in central collisions than in peripheral collisions. The ratios formed by the R\(_{ΔR}\) values in different centrality bins and the values in the 40-80\% centrality bin are presented.}, language = {en} } @article{OPUS4-17230, title = {Search for new phenomena with large jet multiplicities and missing transverse momentum using large-radius jets and flavour-tagging at ATLAS in 13 TeV \(pp\) collisions}, series = {Journal of High Energy Physics}, volume = {34}, journal = {Journal of High Energy Physics}, organization = {The ATLAS Collaboration}, doi = {10.1007/JHEP12(2017)034}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-172302}, year = {2017}, abstract = {A search is presented for particles that decay producing a large jet multiplicity and invisible particles.
