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.

Teng Wang defends his thesis on self-adjusting and linearization techniques based on digital predistortion for communications in UAVs.
Teng Wang defended his thesis titled "A Fasto Engineering Approach High Efficiency Power Amplifier Linearization for Avionics Applications" on December 17 at EETAC, directed by Pere L. Gilabert (TSC-UPC). The thesis provides some guidelines for the design of linearizers based on digital predistortion (DPD) from several perspectives: y) improve the performance of open-loop DPD, ii) provide robustness and reduce the computational complexity of the parameter identification subsystem and, iii ) incorporation of machine learning techniques to favor the auto-tuning of power amplifiers and DPD linearizers with various degrees of freedom to be able to maximize energy efficiency while meeting linearity specifications.
