Adrià Casanovas Hoste defends his thesis on measures of effective neutron capture sections of importance for the study of stellar nucleosynthesis: Adrià Casanovas Hoste defended his thesis, co-directed by Franciscño Calviño (UPC) and César Domingo (IFIC, Valencia), on 27 October at the ETSEIB. Titled "Neutron capture cross section measurement of the heaviest s-process branching 204Tl and of 203Tl at CERN n_TOF", the thesis presents the first ever measurement of the effective neutron capture section of the radioactive isotope of such 204Tl, of special relevance to the slow process of stellar nucleosynthesis, and performed in the CERN n_TOF experiment

Researchers from the DNOLL research group convert the bass chords of a song by the group 'Queen' into an image: Cristina Masoller, Pablo Amil, Donatus Halpaap and Jordi Tiana-Alsina are researchers from the UPC Physics Department at the Terrassa Campus. The team of researchers have detected audio signals at a distance, without listening to the emitter, and have converted them into images using laser light. The experiment, which was performed by recording the first bass chords of the song 'Another one bites the dust' by the British group 'Queen', has been published in the magazine 'Optics Express'. The method has been baptized with the name 'Best Pixel' and has had the collaboration of Italian scientists from the Università degli studi di Catania.

Sergi Mas-Pujol defends his thesis on the management of imbalances between demand and air capacity using deep learning techniques: Sergi Mas-Pujol defended his thesis co-supervised by Dra. Esther Salamí and Dr. Enric Pastor on May 12, 2023 at the Baix Llobregat Campus. Entitled "Deep Learning techniques for Demand-Capacity Balancing", the thesis studies the use of artificial intelligence techniques to improve the detection of air regulations and how to smooth traffic in periods of high demand, proposing different models that have takes into account the needs of the main parties involved (network management entity and airlines) and a reinforcement learning model based on the use of images.

Important results published on a molecular mechanism that causes a type of serious cardiac arrhythmia: Blas Echebarria and Enric Àlvarez, researchers in the Physics department of the research group in Computational Biology and Complex Systems (BIOCOM-SC), together with researchers from the Heart Rate Analysis and Control (ANCORA) research group at the UPC, and other international scientists have identified one of the molecular mechanisms responsible for cardiac alternation. This is an alteration of the heart rhythm that facilitates the induction of ventricular fibrillation, a potentially lethal type of arrhythmia. This discovery, published in the journal Circulation Research (AHA Jounals), opens the door to new pharmacological treatments.

Analysis of the last two centuries of rainfall records in Andalusia for the detection of possible changes caused by global warming: As a result of a collaboration with researchers from the University of Córdoba, M. Carmen Casas and Raúl Rodríguez have evaluated the quality of the rainfall data of Andalusia available since 1870, long before the first modern meteorological stations were put into operation, and have analyzed the different rainfall patterns in the region in pursuit of the detection of possible changes caused by global warming
