To evaluate the short-term, mid-term and long-term follow-up of 285 patients who had undergone percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture (VCF) in our department from 2003 to 2006, and, particularly, to analyse our data on the safety and the usefulness of PVP for durable pain reduction, mobility improvement and the(More)
In the last few years, Network Coding (NC) has been shown to provide several advantages, both in theory and in practice. However, its applicability to battery-operated systems under strict power constraints has not been proven yet, since most implementations are based on high-end CPUs and GPUs. This work represents the first effort to bridge NC theory with(More)
— In this paper, we evaluate the performance of random linear network coding (RLNC) in low data rate indoor sensor applications operating in the ISM frequency band. We also investigate the results of its synergy with forward error correction (FEC) codes at the physical layer in a joint channel-network coding (JCNC) scheme. RLNC is an emerging coding(More)

Abstract— This paper proposes a partial packet recovery scheme, called Packetized Rateless Algebraic Consistency (PRAC). PRAC exploits intra and inter-packet consistency to identify and recover erroneous packet segments, without recourse to(More)
To evaluate the safety and efficacy of transarterial embolization of life-threatening arterial rupture in patients with vascular Ehlers–Danlos syndrome (vEDS) in a single tertiary referral center. We retrospectively analyzed transarterial embolization for vEDS performed at our institution from 2000 to 2012. The indication of embolization was spontaneous(More)
Proposal Summary—Nowadays, since more and more battery-operated devices are involved in applications with continuous sensing, development of an efficient sampling mechanisms is an important issue for these applications. In this paper, we investigate power efficiency aspects of a recently proposed adap-tive nonuniform sampling. This sampling scheme minimizes(More)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract—In this paper, we present an empirical rate-distortion study of a communication scheme that uses compressive sensing (CS) as joint source-channel coding. We investigate the rate-distortion behavior of both point-to-point and(More)
