Assessing the impact of model biases on subseasonal forecast skill

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Relaxation experiments where the nudging was performed towards bias‐corrected integrations of the same model display significantly improved skill at weeks 3 and 4, particularly in the northern extratropics. This indicates that there is a large potential for improving dynamical subseasonal forecasting skill by improved treatment of model biases.

Predictability of North Pacific blocking events: Analogue‐based analysis of historical MIROC6 simulations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The predictability of western and eastern North Pacific blocking events is assessed using analogue‐based diagnostics. Eastern blocks exhibit lower predictability, characterized by faster error growth and higher mean logarithmic divergence rates. The study highlights geographical contrasts in blocking stability.

Performance of the operational ECMWF ensemble in predicting heavy rain associated with the Emilia‐Romagna flood in May 2023

open access: yesWeather, EarlyView.
A devastating flood occurred in May 2023 in the Emilia‐Romagna region in northern Italy after 2 days with widespread accumulated precipitation exceeding 150mm. The event was associated with a quasi‐stationary upper‐level cutoff cyclone. This study investigates the performance of the operational ECMWF ensemble prediction system in capturing the cutoff ...

Understanding Atrial Fibrillation Complexity Through the Lens of Turbulence Dynamics: Implications for Treatment Strategies

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia encountered in clinical practice. Its incidence increases significantly with age and has become a major global public health issue. Although research into the mechanisms of AF has spanned over a century‐ranging from the reentry theory to the rotor hypothesis‐none of these

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

open access: yesExperimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...
