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)
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)
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)
—The IEEE 802.15.4 standard has been attracting strong interest, but in the academic community so far very little research related to the IEEE 802.15.4 MAC has been evaluated experimentally, with real hardware under realistic conditions. This is mainly due to the fact that a stable, open-source IEEE 802.15.4 MAC implementation has been unavailable for a(More)
SUMMARY 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 NO x regulation) and energy optimization. We first discuss a novel regulation architecture, highlighting the(More)
Smoking in hospitals is now forbidden. In several hospitals, however, women in labour are allowed to smoke in designated smoking areas. This study assesses whether smoking during labour increases the carboxyhaemoglobin concentrations in maternal and cord blood, taking into account the number of cigarettes smoked during pregnancy, duration of labour and(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)
