A Generalisation of the Conjugation Method for Polynomial Selection for the Extended Tower Number Field Sieve Algorithm
finite fields discrete logarithm tower number field sieve
2016/6/2
In a recent work, Kim and Barbulescu showed how to combine previous polynomial selection methods with the extended tower number field sieve algorithm to obtain improved complexity for the discrete log...
Time Reversal and Charge Conjugation in an Embedding Quantum Simulator
Charge Conjugation Embedding Quantum Simulator
2016/1/22
A quantum simulator is an important device that may soon outperform current classical computations. A basic arithmetic operation, the complex conjugate, however, is considered to be impossible to be i...
The Multiple Number Field Sieve with Conjugation Method
Discrete Logarithm Finite Field Medium Characteristic
2016/1/7
In this paper, we propose two variants of the Number Field Sieve (NFS) to compute
discrete logarithms in medium characteristic finite fields. We consider algorithms that
combine two ideas, namely th...
Source signature processing in deep water, Gulf of Mexico: comparison between deterministic deconvolution and phase conjugation
oversampling source signature deconvolution
2015/9/29
The Center for Marine Resources and Environmental Technology has been developing a new method to improve the resolution of high-resolution seismic profiling. To achieve this the source signature is re...

2012/4/19
Analysis of the electron density distribution in clusters composed of hydrogen fluoride, water, and ammonia molecules, especially within the hydrogen-bond domains, reveals the existence of both \sigma...
Electronic phase conjugation for nonlinearity compensation in fiber communication systems
fiber communication systems nonlinearity compensation Electronic phase conjugation
2015/5/15
Electronic phase conjugation is proposed for nonlinearity compensation in fiber communications. Coherent detection and I/Q modulation are used to implement phase conjugation. Significant performance i...
Charge conjugation from space-time inversion in QED: discrete and continuous groups
CPT groups space-time inversion Lorentz and Poincar´ e groups
2010/11/29
We show that the CPT groups of QED emerge naturally from the PT and P (or T )subgroups of the Lorentz group. We also find relationships between these discrete groups and continuous groups, like the co...

2010/12/1
A conjugation-free geometric presentation of a funda-mental group is a presentation with the natural topological gener-ators x1, . . . , xn and the cyclic relations.
Optical Phase Conjugation in Chalcogenide Planar Waveguides for Compensating Signal Transmission Effects
Nonlinear optical signal processing Phase conjugation Nonlinear optical devices
2015/6/10
We report optical phase conjugation of wavelength multiplexed signals using a chalcogenide planar waveguide inserted along a transmission link. Distortion compensation of 3×40 Gb/s RZ-DPSK signals pro...
