We show that capillary waves can exist at the boundary between miscible coflowing fluids. unveil interplay transient interfacial stresses and confinement drives progressive transition from well-known inertial regime, characterized by a frequency independent wave number, k∼ω^{0}, to scaling, k∼ω^{2/3}, unexpected for This allows us measure effective tension fluids its rapid decay on timescales never probed so far, which we rationalize with model going beyond square-gradient theories.

Transcatheter aortic valve implantation (TAVI) carries higher risk of post-procedural adverse events than conventional percutaneous cardiovascular interventions. We report our experience about postoperative management protocol adopted in Division.One hundred and ten patients underwent TAVI 108 were transferred to the cardiac intensive care unit (CICU) after procedure. During first 48 hours, vital parameters monitored continuously. Close attention was given rhythm atrio-ventricular conduction...
Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor is the cornerstone of pharmacologic management patients acute coronary syndrome (ACS) and/or those receiving stents. Long-term (>1 year) DAPT may further reduce risk stent thrombosis after percutaneous intervention (PCI) decrease occurrence non-stent-related ischaemic events in ACS. Nevertheless, compared alone, extended use plus increase bleeding that have been strongly linked to adverse outcomes including...
For sufficiently low interfacial tension, spinning drops develop dumbbell shapes, with two large heads connected by a thinner central body. The time evolution of such shapes is exploited to investigate the effective tension (EIT) at boundary between miscible molecular fluids. EIT found be as 250 nN/m in water-glycerol systems, excellent agreement values calculated via an existing phase field model.
We report on the extensional dynamics of spinning drops in miscible and immiscible background fluids following a rotational speed jump. Two radically different behaviors are observed. Drops environments relax exponentially to their equilibrium shape, with relaxation time that does not depend centrifugal force. find an excellent quantitative agreement predicted for quasi-spherical by Stone Bush (Q. Appl. Math.1996, 54, 551), while other models proposed literature fail capture our data. By...
We demonstrate that the elastic modulus and surface energy constant of soft materials can be simultaneously measured by analysing deformation millimetric beads under centrifugal forcing.
We report the existence of capillary waves propagating along boundary between miscible co-flowing fluids. unveil that interplay transient interfacial stresses and confinement drives progressive transition from well-known inertial regime, characterized by a wavenumber independent frequency, $k\sim\omega^{0}$, to an unexpected capillary-wave scaling, $k\sim\omega^{2/3}$. This allows us measure effective tension fluids its rapid decay on time scales never probed so far, which we rationalize...

Large deformations of soft elastic beads spinning at high angular velocity in a denser background fluid are investigated theoretically, numerically, and experimentally using millimeter-size polyacrylamide hydrogel particles introduced drop tensiometer. We determine the equilibrium shapes from competition between centrifugal force restoring surface forces. Considering as neo-Hookean up to large deformations, we show that their modulus energy constant can be simultaneously deduced shape. Also,...
