Subcarrier multiplexed transmission of cellular (900 MHz), personal communications systems (1.8 GHz) and wireless LAN (2.4 GHz) over the fiber has interesting applications. These multi channel radio over fiber links can connect enhanced wireless hot-spots that will support high speed wireless LAN services or low speed cellular services to different customers from the same antenna. Optical pre-f...

Migrating Sockets is the protocol processing component of an end system architecture designed for networking with QoS guarantees. The architecture provides (1) adaptive rate-controlled scheduling of protocol threads in Migrating Sockets, (2) rate-based ow control for reserved rate connections in future integrated services networks, and (3) a constant overhead active demultiplexing mechanism. Mi...

In this first paper we describe the approach followed to design and experimentally test the high speed and broad band analog-to-digital converters (ADC's or digitizers) required for the ALMA project. Our prototypes are based on monolithic digitizers implemented in a BiCMOS 0.35 or 0.25 μm SiGe process with 3 or 8 quantization levels and 4 giga samples per second rate for an input signal from 2 ...

Packet demultiplexing and analysis is a core concern for network security, and has hence inspired numerous optimisation attempts since their conception in early packet demultiplexing filters such as CSPF and BPF. These optimisations have generally, but not exclusively, focused on improving the speed of packet classification. Despite these improvements however, packet filters require further opt...

The ADAPTIVE Communication Environment (ACE) is an object-oriented toolkit that implements strategic and tactical design patterns to simplify the development of concurrent, event-driven communication software. ACE provides a rich set of reusable C++ wrappers, class categories, and frameworks that perform common communication software tasks across a range of operating system platforms. The commu...

Surface-enhanced Raman scattering (SERS) nanoparticles have been engineered to generate unique fingerprint spectra and are potentially useful as bright contrast agents for molecular diagnostics. One promising strategy for biomedical diagnostics and imaging is to functionalize various particle types ("flavors"), each emitting a unique spectral signature, to target a large multiplexed panel of mo...

Biomarker-targeted surface-enhanced Raman scattering (SERS) nanoparticles (NPs) have been explored as a viable option for targeting and imaging multiple cell-surface protein biomarkers of cancer. While it has been demonstrated that this Raman-encoded molecular imaging (REMI) technology may potentially be used to guide tumor-resection procedures, the REMI strategy would benefit from further impr...
