This case-control study was designed to reevaluate the association of the morphology of breast tissue seen on mammograms with breast cancer risk and to assess the relation of diet, especially intake of fat and vitamin A, to the high-risk mammographic images. The cases included 290 patients with newly diagnosed breast cancer who were first treated in Quebec(More)
We consider reliable communications in Body Area Networks (BAN), where a set of nodes placed on human body are connected using wireless links. In order to keep the Specific Absorption Rate (SAR) as low as possible for health safety reasons, these networks operate in low transmit power regime, which however, is known to be error prone. It has been observed(More)
We compared the inhibitory effects of inhaled salbutamol (S), ipratropium (I), and cromoglycate (C) on bronchospasm induced by exercise (EX) or hyperosmolar (HY) saline aerosol in a group of 11 subjects with stable asthma. Each subject had eight tests in a randomized order, four EX and four HY challenges, each preceded by the double-blind inhalation of(More)
This paper describes a new industrial case on automation, for large-scale systems with high environmental impact: the mining ventilation control systems. Ventilation control is essential for the operation of a mine in terms of safety (CO and NOx regulation) and energy optimization. We first discuss a novel regulation architecture, highlighting the interest(More)
In the new era of connectivity, marked by the explosive number of wireless electronic devices and the need for smart and pervasive applications, Machine-to-Machine (M2M) communications are an emerging technology that enables the seamless device interconnection without the need of human interaction. The use of M2M technology can bring to life a wide range of(More)
People worldwide are getting older and this fact has pushed the need for designing new, more pervasive, and possibly cost effective healthcare systems. In this field, distributed and networked embedded systems, such as wireless sensor networks (WSNs), are the most appealing technology to achieve continuous monitoring of aged people for their own safety,(More)
Ambient Assisted Living (AAL) technologies constitute a new paradigm that promises quality of life enhancements in chronic-care patients and elderly people. From a communication perspective, they involve heterogeneous deployments of body and ambient sensors in compex, multihop topologies. Such networks can significantly benefit from the application of(More)
In this paper, we propose a theoretical setup for evaluation of energy efficiency of wireless sensor networks (WSNs) with distributed source coding (DSC) algorithms and packet aggregation (PA). We consider four topologies for DSC and three alternatives for PA, and the system model includes a realistic network architecture with multi-hop communication,(More)
This study describes the evolution in fetal and neonatal mortality rates among twin pairs born in 22 hospitals located in the eastern regions of the province of Quebec in 1976-1978 (n = 776 pairs) and 1982-1985 (n = 712 pairs). It also assesses the contribution of maternal factors, obstetrical care and characteristics of twins in the variation of the risk(More)
In this paper, we analyze and describe the achievable performance of a Wireless Sensor Network (WSN) testbed platform, which has been deployed at the Center of Excellence DEWS (University of L'Aquila, Italy) for positioning applications, and which is implemented using CC2431 sensor nodes developed by Texas Instruments® (TI)/Chipcon. In particular, we(More)
