A reduced 3D-0D fluid–structure interaction model of the aortic valve that includes leaflet curvature

We introduce an innovative lumped-parameter model of the aortic valve, designed to efficiently simulate the impact of valve dynamics on blood flow. Our reduced model includes the elastic effects associated with the leaflets’ curvature and the stress exchan ...

Aircraft Departures Management for Low Altitude Air City Transport based on Macroscopic Fundamental Diagram

Nikolaos Geroliminis

Low-altitude aircraft is being developed as a new mode of urban transport. This will give rise to new urban air transport systems, called low-altitude air city transport (LAAT) systems. Recent works show that the Macroscopic Fundamental Diagram (MFD) is a ...

A mathematical model of the human heart suitable to address clinical problems

Alfio Quarteroni

In this paper, we present a mathematical model capable of simulating the human cardiac function. We review the basic equations of the model, their coupling, the numerical approach for the computer solution of this mathematical model, and a few examples of ...

Stochastic optimization and Markov chain-based scenario generation for exploiting the underlying flexibilities of an active distribution network

Sidi-Rachid Cherkaoui

This paper proposes a scalable stochastic optimization model and a Markov chain-based scenario generation method to benefit from an active distribution network's (ADN's) flexibility. The optimization variables are the dispatch plan, such as the active and ...

Image-Based Computational Hemodynamics Analysis of Systolic Obstruction in Hypertrophic Cardiomyopathy

Alfio Quarteroni

Hypertrophic Cardiomyopathy (HCM) is a pathological condition characterized by an abnormal thickening of the myocardium. When affecting the medio-basal portion of the septum, it is named Hypertrophic Obstructive Cardiomyopathy (HOCM) because it induces a f ...

Increasing Loudness In Audio Signals: A Perceptually Motivated Approach To Preserve Audio Quality

Paolo Prandoni

We present a method to maintain the subjective perception of volume of audio signals and, at the same time, reduce their absolute peak value. We focus on achieving this without compromising the perceived audio quality. This is specially useful, for example ...

Tunable wavelength-stabilized mode-locked thulium-doped fiber laser beyond 2000nm

Camille Sophie Brès, Moritz Bartnick, Gayathri Bharathan

We demonstrate operation of a tunable mode-locked thulium-doped fiber laser, based on a wavelength-selective chirped fiber Bragg grating (CFBG). By applying strain to the CFBG, we shift its reflection band and can thereby tune the emission-wavelength of th ...

Dissecting mechanisms of chamber-specific cardiac differentiation and its perturbation following retinoic acid exposure

Matthias Lütolf, Nicolas Antoine Vincent Broguiere, Giuliana Rossi

The specification of distinct cardiac lineages occurs before chamber formation and acquisition of bona fide atrial or ventricular identity. However, the mechanisms underlying these early specification events remain poorly understood. Here, we performed sin ...

Causal Effect Identification with Context-specific Independence Relations of Control Variables

Negar Kiyavash, Seyed Jalal Etesami, Ehsan Mokhtarian, Fateme Jamshidi

We study the problem of causal effect identification from observational distribution given the causal graph and some context-specific independence (CSI) relations. It was recently shown that this problem is NP-hard, and while a sound algorithm to learn the ...

Status Updates in a multi-stream M/G/1/1 preemptive queue

Emre Telatar, Elie Najm

We consider a source that collects a multiplicity of streams of updates and sends them through a network to a monitor. However, only a single update can be in the system at a time. Therefore, the transmitter always preempts the packet being served when a n ...
