Hospital population density and risk of respiratory infection: Is close contact density dependent?

George Shirreff, Anne C. M. Thiébaut, Bich-Tram Huynh, Guillaume Chelius et autres

Respiratory infections acquired in hospital depend on close contact, which may be affected by hospital population density. Models of infectious disease transmission typically assume that contact rates are independent of density (frequency dependence) or proportional to it (linear density dependence), without justification. …

Assessing respiratory epidemic potential in French hospitals through collection of close contact data (April–June 2020)

George Shirreff, Bich-Tram Huynh, Audrey Duval, Lara Cristina Pereira et autres

The transmission risk of SARS-CoV-2 within hospitals can exceed that in the general community because of more frequent close proximity interactions (CPIs). However, epidemic risk across wards is still poorly described. We measured CPIs directly using wearable sensors given to all present …

A programmable Linux-based FPGA platform for audio DSP

Pierre Cochard, Maxime Popoff, Antoine Fraboulet, Tanguy Risset et autres

Recent projects have been proposing the use of FPGAs (Field Programmable Gate Array) as hardware accelerators for high computing power real-time audio Digital Signal Processing (DSP). Most of them imply specific developments which cannot be re-used between different applications. In this paper, …

Measuring dynamic social contacts in a rehabilitation hospital: effect of wards, patient and staff characteristics

Audrey Duval, Thomas Obadia, Lucie Martinet, Pierre‐Yves Boëlle et autres

Understanding transmission routes of hospital-acquired infections (HAI) is key to improve their control. In this context, describing and analyzing dynamic inter-individual contact patterns in hospitals is essential. In this study, we used wearable sensors to detect Close Proximity Interactions (CPIs) among patients …

Live Group Detection for Mobile Wireless Sensor Networks

Matthieu Lauzier, Antoine Fraboulet, Jean-Marie Gorce, Tanguy Risset

This paper deals with distributed algorithms for monitoring the topology of a dynamic group of mobile wireless sensor networks. We propose two major extensions of a distributed static group consensus algorithm and an experimental implementation. Group consensus algorithms are exploited to let …

When TEDDY meets GrizzLY

Céline Robardet, Vasile-Marian Scuturici, Marc Plantevit, Antoine Fraboulet

Temporal dependencies between multiple sensor data sources link two types of events if the occurrence of one is repeatedly followed by the appearance of the other in a certain time interval. TEDDY algorithm aims at discovering such dependencies, identifying the statically significant …
