Spectroscopy along Decay Chains of Element 114, Flerovium

This thesis focusses on a nuclear spectroscopy experiment conducted to study α-decay chains stemming from isotopes of flerovium (element Z = 114). An upgraded TASISpec decay station was placed behind the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. The fusion-evaporation reactions 48Ca + 242Pu and 48Ca + 244Pu provided a total of 29 flerovium decay chains. The measurement of two new types of even-even flerovium decay chains, starting from 286Fl and 288Fl, respectively, marked the discoveries of (i) an excited state in 282Cn and (ii) the isotope 280Ds. The observations gave further insights into the location of the coveted Island of Stability. With fifteen new decay chains starting from 289Fl, the global data set was doubled for this isotope. Measured decay properties of these chains could provide new evidence of α-decay fine structure of odd-A superheavy nuclei, as predicted by theoretical calculations.The papers included in this thesis cover various aspects of the flerovium experiment. The chapters complement the publications with background information and further details. They include an introduction to the research field of superheavy nuclei, detector development efforts, a description of the experimental setup as well as information on the data analysis and the simulations performed. The chapters also provide a summary of the main results and overarching outlook perspectives.In Paper I, the processing of digitised silicon preamplifier signals were applied to short-lived α-decaying nuclei North-East of Pb. Further preparatory aspects of the experiment as well as applied spectroscopic tools, are covered in Paper III. The TASISpec decay station was upgraded with novel Compex germanium detectors, and their characterisation is given in Paper II. Paper V presents detailed information on the data analysis and statistical assessments applied to the flerovium decay chains. Highlights from the even-even Fl-decay chains are presented in Paper IV and as a press release in Paper VII. Finally, the main findings of the odd-A, 289Fl, decay chains form Paper VI

Colorectal Cancer

Karcinom debelog crijeva jedan je od vodećih zdravstvenih problema u svijetu, osobito u visokorazvijenim zemljama. U našoj zemlji zauzima po učestalosti drugo mjesto među zloćudnim bolestima, u muškaraca iza raka pluća, a u žena iza raka dojke. Prema posljednjim podacima Republičkog registra za rak 1998. godine u Hrvatskoj je ukupno oboljelo 2.238 osoba (1.227 muškaraca i 1.011 žena). Učestalost bolesti se udvostručuje svakih deset godina nakon 40. godine života. Liječenje karcinoma debelog crijeva je multidisciplinarno, što znači da se u velikog broja bolesnika primjenjuju dva ili tri oblika liječenja, odnosno najčešće nakon kirurškog liječenja još i kemoterapija ili kombinacija kemoterapije i zračenjaColorectal cancer is one of the leading health problems in the world, particularly in the highly developed countries. In our country it is on the second place among malignant diseases, in men after lung carcinoma, and in women after breast carcinoma. According to the latest data of the Republic Register of Cancer for the year 1998, in Croatia was a total number of 2238 patients (1227 men and 1011 women). The incidence of the disease is doubling every ten years after the age of forty. The treatment of the colorectal cancer is multidisciplinary, meaning that in a large number of patients two or three ways of treatment are being applied, i.e. most frequently after surgical treatment follows chemotherapy or a combination of chemotherapy and radiation

Synovial Chondromatosis of the Pisotriquetral Joint with Secondary Osteoarthritis: Case Report

There are only a few reported cases of synovial chondromatosis affecting pisotriquetral joint (PT). Osteoarthritis of the PT is also rare and can be as disabling as osteoarthritis of any other joint. We report this to be the unique case of synovial chondromatosis of the PT joint with secondary osteoarthritis

Perception de la parole et IRM : réalisation, évaluation et validation d'un système permettant une stimulation sonore de qualité en cours de séquence IRM

International audienceThis study describes the design and the assessment of a MRI-compatible sound production hardware. This system was developed to permit auditory studies with Magnetic Resonance Imaging (MRI) techniques. An important disadvantage caused by the MR imager is the acoustic noise generated during data acquisition, due to the fast gradient switching interacting with the main magnetic field. Several solutions were explored to reduce noise and to provide audio stimuli with a reasonable quality. The sound production system was first tested by instrumental methods (sound level, spectral analysis). Finally, perceptual tests consisting in intelligibility, semantic decision and prosodic judgement were achieved to validate the installation.Cette étude décrit la réalisation d'un dispositif de stimulation auditive pour un imageur à résonnance magnétique fonctionelle de 3 Tesla. Le plus important probléme de ces systémes réside dans l'émission d'un niveau de bruit considérable au cours de son fonctionnement qui les rend quasi impossible à utiliser pour des études en stimulation auditive.Plusieurs solutions de stimulation de réalisation locale sont proposées pour permettre de gérérer au tympan des sujet une stimulation de qualité raisonnable. Les stimulus ainsi générés sont d'abord testés au moyen de méthodes physiques classiques (analyses acoustiques). Ils sont ensuite testés au moyen de tests d'intelligibilité de décision sémantique et de jugement prosodique afin de les valider pour des études de psycho linguistique et psycho acoustique

MOTChallenge: A Benchmark for Single-Camera Multiple Target Tracking

Standardized benchmarks have been crucial in pushing the performance of computer vision algorithms, especially since the advent of deep learning. Although leaderboards should not be over-claimed, they often provide the most objective measure of performance and are therefore important guides for research. We present MOTChallenge, a benchmark for single-camera Multiple Object Tracking (MOT) launched in late 2014, to collect existing and new data, and create a framework for the standardized evaluation of multiple object tracking methods. The benchmark is focused on multiple people tracking, since pedestrians are by far the most studied object in the tracking community, with applications ranging from robot navigation to self-driving cars. This paper collects the first three releases of the benchmark: (i) MOT15, along with numerous state-of-the-art results that were submitted in the last years, (ii) MOT16, which contains new challenging videos, and (iii) MOT17, that extends MOT16 sequences with more precise labels and evaluates tracking performance on three different object detectors. The second and third release not only offers a significant increase in the number of labeled boxes but also provide labels for multiple object classes beside pedestrians, as well as the level of visibility for every single object of interest. We finally provide a categorization of state-of-the-art trackers and a broad error analysis. This will help newcomers understand the related work and research trends in the MOT community, and hopefully shed some light on potential future research directions.Comment: Accepted at IJC
