Hydrodynamic mechanisms of aggressive collapse events in leading edge cavitation

Transient cavities generated from unsteady leading-edge cavitation may undergo aggressive collapses which are responsible for cavitation erosion. In this paper, we studied the hydrodynamic mechanisms of these events in the leading edge cavitation formed ov ...

Short-term debt and incentives for risk-taking

Erwan Morellec, Francesca Maria Zucchi

We challenge the view that short-term debt curbs moral hazard and demonstrate that, in a world with financing frictions and fair debt pricing, short-term debt generates incentives for risk-taking. To do so, we develop a model in which firms are financed wi ...

Statistical accuracy for estimations of large wood blockage in a reservoir environment

Anton Schleiss, Michael Pfister, José Pedro Gamito de Saldanha Calado Matos, Paloma Furlan

The blockage of weirs or bridges by in-stream wood can reduce the flood discharge capacity, leading to hazardous situations. To assess the related risk, blocking probabilities quantifications are needed. However, large wood has a random behaviour and it is ...

Risk assessment of pedestrian crossings: a stochastic video-based analysis

Adrien Nicolet

Although pedestrian crossings are supposed to guarantee safety, accidents are still frequent. Prior to implementing any measures to address this issue, the safety of the pedestrian crossing must be assessed. Various indices estimating the safety of pedestr ...

Ontology for Strategies and Predictive Maintenance models

Gökan May, Sangje Cho, Marlène Hildebrand-Ehrhardt

As of today, to cope with traditional maintenance policies such as reactive and preventive maintenance, the manufacturing companies need the deployment of adaptive and responsive maintenance strategies. Meanwhile, the advent of Industry 4.0 leads the maint ...

Systematic sensor placement for structural anomaly detection in the absence of damaged states

Jan Sickmann Hesthaven, Caterina Bigoni, Zhenying Zhang

In structural health monitoring (SHM), risk assessment and decision strategies rely primarily on sensor responses. Simulated data can be generated to emulate the monitoring phenomena under different natural operational and environmental conditions in order ...

Closing down the shop: Optimal health and wealth dynamics near the end of life

Julien Hugonnier, Pascal St-Amour, Florian Pelgrin

Near the end of life, health declines, mortality risk increases, and curative care is replaced by uninsured long-term care, accelerating the fall in wealth. Whereas standard explanations emphasize inevitable aging processes, we propose a complementary clos ...

Role of glutathione S-transferases and the mercapturic acid pathway in the biotransformation potential of two zebrafish (Danio rerio) test systems: early life stages and PAC2 cells

Alena Tierbach

Zebrafish (Danio rerio) early life stages provide an important model for chemical risk assessment due to their genetic similarity to humans and the availability of well-established high-throughput techniques. Cells isolated from zebrafish conserve all thes ...

Biological fluid dynamics of airborne COVID-19 infection

Andrea Rinaldo

We review the state of knowledge on the bio-fluid dynamic mechanisms involved in the transmission of the infection from SARS-CoV-2. The relevance of the subject stems from the key role of airborne virus transmission by viral particles released by an infect ...

Clinical relevance of low-densityPlasmodium falciparumparasitemia in untreated febrile children: A cohort study

Mary-Anne Hartley

Background Low-density (LD)Plasmodiuminfections are missed by standard malaria rapid diagnostic tests (standard mRDT) when the blood antigen concentration is below the detection threshold. The clinical impact of these LD infections is unknown. This study i ...
