Burst-mode electronic dispersion compensation in long reach PONs
Long reach passive optical networks (LR-PONs), which integrate fibre-to-the-home with metro networks, have been the subject of intensive research in recent years and are considered one of the most promising candidates for the next generation of optical access networks. Such systems ideally have …

Dynamically reconfigurable long-reach PONs for high capacity access
Fibre-to-the-Premises (FTTP) is currently seen as the ultimate in high-speed transmission technologies for delivering ubiquitous bandwidth to customers. However, as the deployment of network infrastructure requires a substantial investment, the main obstacle to fibre deployment is that of financial …

A novel storage area network (SAN) extension solution over passive optical networks (PONs)
… SAN extension over passive optical networks (S-PONs), has been proposed to address the above problems. PONs are the mainstream wireline technology for upgrading the megabit-level access solutions (such as xDSL and Cable Modem) into gigabit-level broadband access. To tackle the scalability …

Design of 10 Gb/s burst-mode receivers for high-split extended reach PONs
… extended reach passive optical networks (PONs). The designed receiver incorporates two very advanced features. Firstly, the burst-mode receiver locks its gain setting within 6 ns avoiding packet loss due to gain switching during data payload reception. Secondly, the burst-mode receiver …

Examining Nursing Presence in the Acute Care Setting as an Indicator of Patient Satisfaction with Nursing Care
… and research. The Presence of Nursing Scale, PONS (Kostovich, 2002) was used in this study to test its reliability and determine its validity against a single-item measure of patient satisfaction with the care given by a particular nurse. In the 75-patient sample, the PONS was found to be …

The effects of catalase and kisspeptin overexpression on amyloid peptide toxicity
… the present study. Tissue sections from the AD pons region were immunohistochemically stained to determine if catalase or KP colocalized with Aβ deposits. The immunohistochemistry results show that immunoreactive KP or immunoreactive catalase co-localizes with immunoreactive Aβ in AD pons …

SOA enhanced optical line terminal for future optical access network
Future passive optical networks (PONs) aim to deliver data rates of 100 Gb/s per wavelength using intensity-modulation direct detection (IM/DD) and up to 400 Gb/s per wavelength using coherent technology. Achieving these targets requires overcoming the large dynamic range of burst-mode upstream …

Genomic and Molecular Characterization of Brainstem Glioma
… we identified four distinct clusters termed H3-Pons, H3-Medulla, IDH, and PA-like, each associated with unique genomic and clinical profiles. The majority of tumors within H3-Pons and H3-Medulla harbored H3F3A mutations, but showed distinct methy- lation patterns that correlated with anatomical …

Modules in the brainstem and spinal cord underlying motor behaviors
… which areas of the central nervous system are responsible for structuring and combining muscle synergies remains an open question. In my thesis, I have addressed the question whether the brainstem and spinal cord are involved in structuring and combining muscle synergies in order to execute a …
