Jet measurements and reconstruction biases in proton-proton and Pb-Pb collisions with ALICE at the LHC
No full textDiese Dissertation untersucht Jets in Proton-Proton- (pp) und Schwerionenkollisionen am Large Hadron Collider (LHC) des Forschungszentrums CERN. Es wurden Messungen des ALICE-Experiments aus dem Jahr 2010 analysiert. In den Blei-Blei-Kollisionen mit Schwerpunktsenergien von 2,76 TeV pro Nukleonpaar werden Energiedichten erwartet, bei denen ein neuer Materiezustand, das Quark-Gluon-Plasma (QGP), entsteht. Jets, Bündel aus hochenergetischen Teilchen, fungieren als Sonden zur Vermessung des Mediums. Durch das QGP wird die Fragmentation der Jets beeinflusst, wobei pp-Kollisionen als Referenzmessung dienen. Diese Arbeit präsentiert Ergebnisse der Jet-Fragmentation aus pp-Kollisionen mit Energien von 7 TeV. Des Weiteren werden Untersuchungen zum Übergangsstrahlungsdetektor (TRD) von ALICE als Trigger-Detektor für Jets vorgestellt. Für Jet-Analysen in Schwerionenkollisionen diskutiert die Arbeit detailliert den vorhandenen Ereignisuntergrund und dessen Fluktuationen

No full textAccurate segmentation of cancer from surrounding healthy breast tissues in magnetic resonance imaging (MRI) without intravenous administration of contrast agents, is a question of wide interest. Current standard-of-care dynamic contrast-enhanced MRI (DCE) depends on Gadolinium contrast. Diffusion-weighted MRI (DWI) avoids the use of contrast since it is able to report on tissue microstructure by detecting diffusion of water molecules and has shown large potential in several breast cancer settings, including assessment of treatment response.
However, the current application of DWI for quantitative studies requires radiologists to manually define tumors based on DCE, prior to transferring the defined regions of interest (ROIs) to the DWI image space for analysis.
In this thesis, we investigated alternative methods to DCE for breast tumor definition and neoadjuvant treatment response evaluation: simultaneous positron emission tomography and MRI (PET/MRI), and optimizing an advanced DWI model, Restriction Spectrum Imaging (RSI), for use in the breast. Since meaningful assessment by the RSI model requires knowledge about the underlying breast diffusion properties, we investigated the optimal fitting of diffusion signal for all voxels in cancer and healthy breast tissues. Furthermore, the optimized RSI model was applied for neoadjuvant treatment response evaluation.
We found that tumor definition using our novel semi-automatic PET/MRI segmentation method, GMM-PET, mimics results normally attained through DCE by successfully tracking the same changes in functional parameters for assessment of neoadjuvant treatment. Secondly, optimal fitting of diffusion signal for all voxels in cancer and healthy breast tissues resulted in a three-component RSI model, with globally-determined component-specific apparent diffusion coefficients (ADCs) that decomposed the diffusion signal to correspond to major anatomical components in healthy breast tissues. These results were then applied for optimized discrimination of cancer from healthy breast tissues directly on DWI images, which yielded the derived RSI parameter, C1C2 that showed highly promising discriminatory performance superior to conventional DWI estimates. The three-component RSI model was further used to develop an automatic tissue classifier (RSI classifier) that was able to assess treatment response after only 3 weeks of neoadjuvant treatment and was found to have similar accuracy to DCE in assessing residual tumor post-therapy.
Our novel methodologies, GMM-PET and three-component RSI model-derived C1C2 parameter, can detect breast cancer without the use of Gadolinium contrast. Of particular interest, the highly promising diagnostic performance of C1C2 was determined using data acquired across different sites, scanners, and imaging acquisition protocols. This suggests a readily available clinical utility that may reduce the need to pre-identify lesions on nondiffusion modalities altogether. The finding that the automatic RSI classifier can assess early response to neoadjuvant treatment is important for improved clinical decision-making to enable tailored treatment regimens

Znowu razem, czyli o trzech woluminach z księgozbioru Andrzeja Frycza Modrzewskiego we flamandzkich oprawach plakietowych. Znalezisko ze zbiorów Biblioteki Uniwersyteckiej w Uppsali i Biblioteki Uniwersyteckiej w Poznaniu
No full textDuring works on the reconstruction of the book collection from the Jesuit College in Poznań the researchers came across three volumes with characteristic Flemish Panel-Stamped decorated bindings, in which designs were stamped into the leather cover by a block, into which the image had been carved or incised. The bindings were made in Leuven, in bookbinding workshops that placed their monograms of the following letter combinations: “IP” (Jacob Pandelaert?) and “IB” (Jacob Bathen). Two of the volumes are now kept in the University Library in Uppsala, while one of them is held in Poznań University Library. These are bookbinding blocks that in total include 11 works. The present article presents the history of the three volumes. Following an analysis of the numerous marginal notes included in the volumes it was possible to establish that that the first owner of the volumes had been the writer, humanist and reformer Andrzej Frycz Modrzewski (ca. 1503–1572). Modrzewski had most probably purchased the volumes in Leuven in September 1549. Subsequently, the books were taken over by Stanisław Karnkowski (1520–1603), who donated them to Poznań-based Jesuits. This article contributes to the knowledge on the private book collection of Modrzewski. A particular attention should be given to the editions of the works of Piotr Ramus (Pierre de la Ramée) and Joachim Perion, specifically collected for a purpose by Modrzewski.W trakcie prac nad rekonstrukcją księgozbioru kolegium jezuitów w Poznaniu uwagę zwróciły trzy woluminy w charakterystycznych flamandzkich oprawach plakietowych. Oprawy wykonano w Leuven, w warsztatach introligatorskich monogramistów „IP” (Jacob Pandelaert?) oraz „IB” (Jacob Bathen). Dwa woluminy znajdują się obecnie w Bibliotece Uniwersyteckiej w Uppsali, a jeden w Bibliotece Uniwersyteckiej w Poznaniu. To klocki introligatorskie zawierające łącznie 11 dzieł. W artykule opisano historię tych trzech woluminów. Dzięki analizie licznych not marginalnych ustalono, że pierwszym właścicielem ksiąg był pisarz, humanista i reformator Andrzej Frycz Modrzewski (ca 1503–1572). Zakupił je w Leuven najpewniej we wrześniu 1549 roku. Później księgi trafiły w ręce Stanisława Karnkowskiego (1520–1603), który przekazał je poznańskim jezuitom. Artykuł wzbogaca wiedzę o prywatnym księgozbiorze Modrzewskiego. Wśród odnalezionych dzieł na szczególną uwagę zasługują świadomie zebrane przez Modrzewskiego edycje prac Piotra Ramusa (Pierre’a de la Ramée) i Joachima Periona
