(2021-01-01)As a follow-up of a previous work of the authors, this work considers uniform global time-renormalization functions for the gravitationalN-body problem. It improves on the estimates of the radii of convergence obtained ...
(2021-01-01)This work considers the gravitational N-body problem and introduces global time-renormalization functions that allow the efficient numerical integration with fixed time-steps. First, a lower bound of the radius of convergence ...
An Algorithm based on continuation techniques for minimization problems with highly non linear equality constraints (2021)We present an algorithm based on continuation techniques that can be applied to solve numerically minimization problems with equality constraints. We focus on problems with a great number of local minima which are hard to ...
Systematic Characterization of High-Power Short-Duration Ablation: Insight From an Advanced Virtual Model (2021)High-power short-duration (HPSD) recently emerged as a new approach to radiofrequency (RF) catheter ablation. However, basic and clinical data supporting its effectiveness and safety is still scarce
Chronic stimulation induces adaptive potassium channel activity that restores calcium oscillations in pancreatic islets in vitro (2020-04-01)Insulin pulsatility is important to hepatic response in regulating blood glucose. Growing evidence suggests that insulin-secreting pancreatic β-cells can adapt to chronic disruptions of pulsatility to rescue this physiologically ...
