Damaged wires

Digital wires

E lectrical wires transport energy and information and often both. For example, electrical power cords deliver electrical energy from wall outlets to computers, whereas Ethernet cable transports information in the form of electrical pulses from the internet modem to the computer and back. USB cables are used to both charge the battery of MP3 players and to load digital music on the player. Desp...

Quantum Wires

Optical 'shorting wires'.

Connecting lumped circuit elements in a conventional circuit is usually accomplished by conducting wires that act as conduits for the conduction currents with negligible potential drops. More challenging, however, is to extend these concepts to optical nanocircuit elements. Here, following our recent development of optical lumped circuit elements, we show how a special class of nanowaveguides f...

Semiconducting polymer quantum wires

Semiconducting polymer heterostructures with strong two-dimensional quantum confinement of excitons are prepared by self-assembly of two conjugated polymers in binary blends. Exciton confinement effects in the semiconducting polymer quantum wires were observed at room temperature by photoluminescence excitation and photoluminescence spectroscopies and by electric field-induced photoluminescence...

Getting Your Wires Crossed

Things should be as simple as possiblèand no simpler', so they say. This paper is about simplifying a construct in Ruby, to reduce the complexity of the algebra without sacriicing expressive power. Ruby, for which Mary Sheeran is largely responsible, is a language of relations and a collection of rules { equalities { for algebraic transformation of expressions in that language. The presentation...
