A CMOS rail-to-rail linear VI-converter [PDF]

open access: yes, 1995
A linear CMOS VI-converter operating in strong inversion with a common-mode input range from the negative to the positive supply rail is presented. The circuit consists of three linear VI-converters based on the difference of squares principle.

Adaptive Phase Measurements in Linear Optical Quantum Computation [PDF]

open access: yes, 2005
Photon counting induces an effective nonlinear optical phase shift on certain states derived by linear optics from single photons. Although this no nlinearity is nondeterministic, it is sufficient in principle to allow scalable linear optics quantum ...

A logistical perspective on the potential for modal shift of freight from road to rail in Great Britain [PDF]

open access: yes, 2003
Freight modal shift from road to rail is a potential means by which the negative environmental and social impacts of transport can be reduced. This paper explores recent supply chain changes and assesses their impacts on the mode choice decision-making ...

Greenhouse gas considerations in rail infrastructure in the UK [PDF]

open access: yes, 2015
Transportation-related greenhouse gas (GHG) emissions account for an increasing proportion of total emissions in the UK and globally. The provision of rail transit is popularly proposed to reduce transport GHG emissions, but the provision of new ...

Noise analysis of single-qumode Gaussian operations using continuous-variable cluster states [PDF]

open access: yes, 2014
We consider measurement-based quantum computation that uses scalable continuous-variable cluster states with a one-dimensional topology. The physical resource, known here as the dual-rail quantum wire, can be generated using temporally multiplexed ...

Information gap for classical and quantum communication in a Schwarzschild spacetime [PDF]

open access: yes, 2012
Communication between a free-falling observer and an observer hovering above the Schwarzschild horizon of a black hole suffers from Unruh-Hawking noise, which degrades communication channels. Ignoring time dilation, which affects all channels equally, we

Results From an Analysis of the Mode Choice Decisions of Long Distance Business Travellers [PDF]

open access: yes, 1986
Mode choice models for long distance business travellers have been calibrated, using data on actual choices, generally with the objetive of deriving demand elasticities and values of time for use in forecasting.
