extensive researches on wireless sensor networks (wsns) have been performed and many techniques have been developed for the data link (mac) layer. most of them assume single-channel mac protocols. in the usual dense deployment of the sensor networks, single-channel mac protocols may be deficient because of radio collisions and limited bandwidth. hence, using multiple channels can significantly ...

PURPOSE To investigate whether apoptosis plays a notable role in degeneration of corneal endothelial cells in patients with Fuchs' dystrophy. METHODS Forty-seven corneal buttons from 41 patients with Fuchs' dystrophy were studied. Nucleus labeling, transmission electron microscopy (TEM), and TdT-dUTP terminal nick-end labeling (TUNEL) were used to detect apoptosis. TEM and TUNEL were performe...

In 1906 Ernst Fuchs described a condition including heterochromia, unilateral inflammatory signs such as fine “microgranulomatous” keratic precipitates (KPs) as well as unilateral degenerative signs including iris atrophy and vitreous strands. He called the disease heterochromic cyclitis, more precisely his words were “cyclitis associated with heterochromia”, which would later be known by the e...

This paper presents a novel method to disseminate sensor data in a wireless sensor network, called D3 (Data-centric Data Dissemination). The method combines the advantages of data-centric routing like SPIN and directed diffusion and energyefficient MAC protocols such as S-MAC and T-MAC. The protocol’s strengths are its energy-efficiency and its simplicity. Messages are transmitted using broadca...

We have compared the ability of the Mycobacterium Growth Indicator Tube (MGIT) system, a new culture method with an oxygen-sensitive fluorescent sensor, to recover mycobacteria from sputum samples with the abilities of egg-based medium and the Septi-Chek AFB system. We have also assessed the clinical utility of the AccuProbe or the AMPLICOR-PCR assay to directly identify Mycobacterium tuberculo...

A method is presented (with standard examples) based on an elementary complex integral expression, for developing Frobenius series solutions for second-order linear homogeneous ordinary Fuchs differential equations. The method reduces the task of finding a series solution to the solution, instead, of a system of simple equations in a single variable. The method is straightforward to apply as an...

PURPOSE To investigate potential associations of the ICAM-1 gene polymorphisms and Fuchs uveitis in a cohort of Italian patients. METHODS Seventy-one consecutive Italian patients affected by Fuchs uveitis were observed at the Ocular Immunology Unit, Arcispedale S. Maria Nuova (Reggio Emilia, Italy) from 2002 to 2008. Two hundred twenty-six healthy Italian blood donors from the same geographic...
