Implementation and Calibration of a Deep Neural Network to Predict Parameters of Left Ventricular Systolic Function Based on Pulmonary and Systemic Arterial Pressure Signals

Simone Deparis, Luca Pegolotti, Jean Bonnemain

The evaluation of cardiac contractility by the assessment of the ventricular systolic elastance function is clinically challenging and cannot be easily obtained at the bedside. In this work, we present a framework characterizing left ventricular systolic f ...

Load transfer approach for the geotechnical analysis of energy piles in a group with slab

Lyesse Laloui, Melis Sütman, Elena Ravera

Thermally induced group effects characterise closely spaced energy piles. It has been observed experimentally that the behaviour of energy piles subjected to mechanical and thermal loads, in which the piles are located sufficiently close to each other, is ...

Nonlinear piezoelectric vibration energy harvester with frequency-tuned impacting resonators for improving broadband performance at low frequencies

Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero, Robert Andrew Lockhart

The paper reports on a nonlinear frequency up-converting vibration energy harvester with enhanced broadband performance below 50 Hz, which is attained by leveraging vibro-impact interaction between two high-frequency piezoelectric generators and two low-fr ...

Origin of apparent light-enhanced and negative capacitance in perovskite solar cells

Ulf Anders Hagfeldt, Wolfgang Richard Tress

So-called negative capacitance seems to remain an obscure feature in the analysis of the frequency-dependent impedance of perovskite solar cells. It belongs to one of the puzzling peculiarities arising from the mixed ionic-electronic conductivity of this c ...

SESTET: A spatially explicit stream temperature model based on equilibrium temperature

Andrea Rinaldo, Enrico Bertuzzo, Luca Carraro

Stream-water temperature is a key variable controlling chemical, biological, and ecological processes in freshwater environments. Most models focus on a single river cross-section; however, temperature gradients along stretches and tributaries of a river n ...

Using an amplitude analysis to measure the photon polarisation in B -> K pi pi gamma decays

Olivier Schneider, Frédéric Blanc, Violaine Bellée, Preema Rennee Pais

A method is proposed to measure the photon polarisation parameter.. in b. s. transitions using an amplitude analysis of B. Kpp. decays. Simplified models of the Kpp system are used to simulate B+. K+ p -p+. and B0. K+ p -p0. decays, validate the amplitude ...
