Cosmic rays, high-speed charged particles traversing the universe, yield crucial insights into cosmic phenomena. Understanding the production, acceleration, and propagation of these particles requires analyzing the relative abundances of different isotopes, which relies on precise mass measurements. The Alpha Magnetic Spectrometer (AMS) on the International Space Station provides these...

Amyotrophic Lateral Sclerosis (ALS) is a rapidly progressive neurodegenerative disorder characterized by progressive loss of motor neurons in the brain and spinal cord, leading to muscular weakness and ultimately death. Life expectancy is 3 to 5 years after disease onset, there is no cure and disease heterogeneity make it difficult to understand its underlying mechanisms. This research project...

4. Spherical accretion of a Vlasov gas to a Kerr black hole

Astrophysical compact objects are known to attract matter in their surroundings, in a process known as accretion. This is one of the most important contributions to the formation and evolution of large-scale structures such as galaxies, stars and compact objects. In this work, we investigate relativistic collisionless accretion to rotating black holes. First steps towards the implementation of...

8. Using Machine Learning and Fundamental Analysis to Find the Intrinsic Value of Stocks

Bernardo Frazão

Nowadays, the stock market’s complexity and volatility pose significant challenges to traditional investment strategies. To address these issues, combining machine learning techniques with fundamental analysis provides a more advanced approach to determining the intrinsic value of stocks. By leveraging models such as Random Forest, Support Vector Machines (SVM), and XGBoost, alongside key...

9. Muon Energy Spectrum From The Analysis of Inclined Shower Footprint

Pedro Tomé

There is a discrepancy between the number of muons detected in the Pierre Auger observatory detectors and the ones obtained by air shower simulations. In this work, the GEANT4 simulation code is used to analyse footprints of inclined showers starting from basic simulations without realistic parameters and imposing each parameter one by one in other to better study where the simulations fail to...

5. Kinetic theory of Fermi-boson systems

Pedro Silva

27/06/2024, 15:45

In this work, we explore the dynamics of coupled quantum systems comprising both
fermionic and bosonic particles, focusing on their collective behaviors and emergent
phenomena in graphene. Conventional research frequently isolates a main species and
examines its characteristics either independently of or in equilibrium with nearby
species. Here we diverge by studying mixed systems with...

10. Development of a GATE model for three-dimensional dosimetric estimates of a PET/CT system

Liver cancer is one of the most commonly diagnosed cancers and a leading cause of cancer-related deaths worldwide due to its high malignancy and typically late diagnosis. Radioembolization (RE) with Yttrium-90 (Y90) loaded glass microspheres is a recent Nuclear Medicine (NM) treatment for unresectable liver tumors. In this procedure, Y90 microspheres are delivered via a microcatheter into the...

11. Magnetoresistive Devices for Industrial Applications: Improvement of Thermal Robustness

Patrícia Curado

27/06/2024, 16:15

Magnetoresistive sensors utilize multilayers of magnetic and non-magnetic thin films to convert magnetic field changes into electrical resistance variations. Critical components include the sensing layer and the reference layer, stabilized by an exchange bias with an antiferromagnetic layer. The performance of these sensors is influenced by factors such as layer thickness, material...
