چکیده
Just as engineers learnt to harness the power of electrons in transistors and microchips—which revolutionized modern society—physicists and biologists are now learning how to tame photons. Their work is generating exciting new possibilities for optical microscopy, with a resolution and level of detail hitherto undreamt of. Biophotonics is a new and exciting research field that is already delivering substantial dividends in a wide range of applications from fundamental medical research to diagnosis, therapy and surgery. For a long time the resolution of optical microscopes had been considered to be insufficient for most biological research applications. Consequently, optical microscopes were largely confined to classrooms and pathology laboratories until innovations, such as fluorescence microscopy and laser confocal microscopy, began to bring biophotonics back into the light. In combination with computerassisted image analysis and improved sample preparation methods (Hunter, 2005), various other technological advances have provided even higher levels of resolution and accuracy. These have allowed optical techniques to capitalize on the advantage that they always had over X-ray crystallography or electron microscopy—the ability to observe biochemical processes in real time.

Fiat Lux: A Fluorescent Lamp Tkansceiver
The prevalence of electric discharge illumination has led us to consider ways to use discharge lamps for communication. This paper describes an optical transceiver system which transmits by modulating the lamp arc. The prototype power electronic lamp ballast uses a pulse frequency modulation scheme which ensures no perceptible flicker.
متن کاملFiat categorification of the symmetric inverse semigroup and the semigroup
Starting from the symmetric group Sn , we construct two fiat 2-categories. One of them can be viewed as the fiat “extension” of the natural 2-category associated with the symmetric inverse semigroup (considered as an ordered semigroup with respect to the natural order). This 2-category provides a fiat categorification for the integral semigroup algebra of the symmetric inverse semigroup. The ot...
متن کاملFeige-Fiat-Shamir ZKP Scheme Revisited
In networks and entity groupings that have sensitive resources, user identification is a crucial requirement for secure access, communication and transactions involving those resources. However, there are networks and entity groupings that require entity authentication while preserving the privacy of the entity being authenticated. There are several zero-knowledge protocols (ZKP) including the ...
متن کاملPost-quantum Security of Fiat-Shamir
The Fiat-Shamir construction (Crypto 1986) is an efficient transformation in the random oracle model for creating non-interactive proof systems and signatures from sigmaprotocols. In classical cryptography, Fiat-Shamir is a zero-knowledge proof of knowledge assuming that the underlying sigma-protocol has the zero-knowledge and special soundness properties. Unfortunately, Ambainis, Rosmanis, and...
