1. 1. Time-Based Reconstruction of Hyperons at PANDA at FAIR

   Författare :Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Sophie Grape; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PANDA; FAIR; hyperons; track reconstruction; online; cellular automaton; 4D tracking; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

   Sammanfattning : The PANDA (anti-Proton ANnihilation at DArmstadt) experiment at the future FAIR (Facility for Anti-proton and Ion Research) offers unique possibilities for performing hyperon physics.The almost full 4π coverage of the detector will enable the reconstruction of both hyperon and antihyperon which will be created together in proton-antiproton collisions.

3. 2. Time for Hyperons : Development of Software Tools for Reconstructing Hyperons at PANDA and HADES

   Författare :Jenny Regina; Karin Schönning; Michael Papenbrock; Pawel Marciniewski; Laura Fabbietti; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadron physics; Hyperon; Track reconstruction; 4D tracking; Free-streaming data; Kinematic fitting; PANDA; HADES; Fysik med inriktning mot kärnfysik; Physics with specialization in Nuclear Physics;

   Sammanfattning : The PANDA experiment at FAIR offers unique possibilities for performing hyperon physics. The detector will enable the reconstruction of both hyperon and antihyperon, which will be created together in proton-antiproton collisions. This enables investigations of the strong interaction in the non-perturbative regime. LÄS MER

4. 3. Quantification of 4D Left Ventricular Blood Flow in Health and Disease

   Författare :Jonatan Eriksson; Tino Ebbers; Carl-Johan Carlhäll; Gianni Pedrizzetti; Linköpings universitet; []
   Nyckelord :MRI; relative pressure; 4D flow; quantification; turbulent kinetic energy; dilated cardiomyopathy; magnetic resonance imaging; physiology; cardiac function; diastolic dysfunction;

   Sammanfattning : The main function of the heart is to pump blood throughout the cardiovascular system by generating pressure differences created through volume changes. Although the main purpose of the heart and vessels is to lead the flowing blood throughout the body, clinical assessments of cardiac function are usually based on morphology, approximating the flow features by viewing the motion of the myocardium and vessels.

5. 4. Measurement and Analysis of Intracardiac Blood Flow and Vortex Ring Formation

   Författare :Johannes Töger; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood flow; dynamical systems; magnetic resonance imaging; heart failure; vortex ring formation;

   Sammanfattning : Increased understanding of the pumping mechanics of the heart are of great importance to develop diagnostics, treatment and prognostics for cardiovascular diseases. Blood flow in the heart is connected to its anatomy and function, and may therefore be a sensitive marker of cardiac health and disease. LÄS MER

7. 5. Spatio-temporal modeling of morphology and gene-expressions during C.elegans embryogenesis using a new imaging framework

   Författare :Johan Henriksson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Many aspects of ontogenesis, the process whereby an organism develops from the fertilized egg to a grown adult, are still poorly understood, despite having been studied since Aristotle's time. The advent of modern biology with the sequencing of entire genomes and mapping of all genes offers the promise that one day we will understand how genes function to regulate cell division and differentiation.
