CMOS implementations for RF applications often employ technology modifications to reduce the silicon substrate loss at high frequencies. The most common techniques include the use of a high-resistivity substrate (ρ>10Ω-cm) or silicon-on-insulator (SOI) substrate and precise bondwire inductors [1, 2]. However, these techniques are incompatible with low-cost CMOS manufacture. This design demonstr...

There are many benefits to implementing a service oriented architecture (SOA), such as the efficiency gained in utilizing shared resources, the flexibility of composing systems with model-based constructs, and the ability to incorporate centralized policies and oversight mechanisms. However, as services proliferate and the applications that consume them get more complex, the need to better mana...

Fibre Raman amplifiers are being deployed in many new long-haul and ultra long-haul fibre-optic transmission systems, making them the first and most widely commercialized nonlinear optical devices in telecommunications. One of the main reasons for this is their improved noise figure and reduced nonlinear penalty of fibre systems hence allowing for longer amplifier spans. In this paper, we have ...

This work reports a multipurpose highly linear ultrawideband amplifier with gain-bandwidth product (GBP) of 1.75 THz, the highest reported in any monolithic microwave integrated circuit (MMIC) process. A transimpedance is cascaded distributed amplifier, emulating receiver subsystem. Using diamond heat spreader, to dissipate from transistors, amplification subsystem can achieve very high output ...

BACKGROUND Current Health Canada instructions for use of the dopamine agonists (DA), pramipexole and ropinirole, state that Parkinson's disease (PD) patients should be told not to drive. The objective was to assess neurologists' actual clinical practice concerning driving advice they give to PD patients starting a DA. METHODS An online survey was created consisting of 4 items regarding demogr...

The government of the German state of North-Rhine Westphalia is considering the creation of a state-wide long-term repository for digital content from the cultural heritage domain, which at the same time will act as a pre-aggregator for the Deutsche Digitale Bibliothek and the Europeana. The following describes a software architecture that relies exclusively on existing open source software com...

The FPGA (Field Programmable Gate Array) constitute of many programmable modules like Configuration Logic Blocks (CLBs), Block Random Access Memories (BRAM), DSP 48 blocks and Input/output (I/O) modules. The CLBs are the main programmable logic units which consist of different number of logic slices and each slice contains different number of LUTs and flips flops depending upon the FPGA device ...

Optical distribution networks using remotely pumped erbium-doped fiber amplifiers (EDFAs) with a single pump source at the head end can conveniently provide signal gain without adding to the power-consumption cost and management complexity of having multiple locally pumped EDFAs in densely populated metropolitan areas. We introduce an analytical model for understanding the basic physical founda...

The Transform model is based on the concept of transformation of access rights. It unifies a number of diverse acccsscontrol mechanisms such as amplification, copy flags, separation of duties and synergistic authorization. In this paper we describe a distributed architecture for implementing Transform. Our architecture is based on capabilities with identities of subjects buried in them. This en...

A monolithically integrated device combines 40 GHz dual mode-locked operation with the wide tuning range (>40nm) of sampled-grating DBR lasers, while further being integrated to an SOA and a potentially high-speed modulator. OCIS codes: (250.5300) Photonic integrated devices; (140.3600) Lasers, tunable; (140.4050) Mode-locked lasers
