We calculate the probability of success of block-hiding mining strategies in bitcoin-like networks.
These strategies involve building a secret branch of the block-tree and publishing it

Testing Nonclassicality and Non-Gaussianity in Phase Space
Nonclassicality Non-Gaussianity Phase Space
2016/1/22
We theoretically propose and experimentally demonstrate a nonclassicality test of a single-mode field in phase space, which has an analogy with the nonlocality test proposed by Banaszek and Wódkiewicz...
Robot Self-Characterisation of Experience Using Trajectories in Sensory-Motor Phase Space
environmental interaction interaction characterisation informaiton distance factal dimension AIBO robot
2015/8/3
We describe sensorimotor phase-plots constructed using information theoretical methods from raw sensor data as a way for a robotic agent to characterise its interactions and interaction history. Measu...
Effect of Ion Dynamics on the Evolution of Electron Phase-space Holes
Ion dynamics Electron holes Transverse instability Magnetized plasma
2013/10/3
The evolution of two-dimensional (2D) electron phase-space holes (electron holes) has been previously investigated with electrostatic Particle-in-Cell (PIC) simulations, which neglect ion dynamics. Th...
Phase space parametrization of rain: the inadequacy of the gamma distribution
Phase space parametrization of rain the inadequacy of gamma distribution
2012/11/23
We show that the Gamma distribution is not an adequate fit for the probability density function of drop diameters using the Kolmogorov-Smirnov goodness of fit test. We propose a different parametrizat...

Experimental phase-space-based optical amplification scar modes Optics
2012/4/20
Waves billiard which are chaotic in the geometrical limit are known to support non-generic spatially localized modes called scar modes. The interaction of the scar modes with gain has been recently in...
Inhomogeneity of the phase space of the damped harmonic oscillator under Levy noise
Inhomogeneity of the phase space damped harmonic oscillator Levy noise Statistical Mechanics
2012/4/19
The damped harmonic oscillator under symmetric L\'{e}vy white noise shows inhomogeneous phase space, which is in contrast to the homogeneous one of the same oscillator under the Gaussian white noise, ...

Maximally Entangled Two Qubit Phase Space Quantum Physics
2011/9/29
Abstract: Motivated by M\"obius transformation for symmetrical points under the generalized circle in complex plane, the system of symmetrical spin coherent states corresponding to antipodal qubit sta...
A White Noise Approach to Phase Space Feynman Path Integrals
White Noise Analysis Feynman Integrals Mathematical Physics
2011/1/18
The concepts of phase space Feynman integrals in White Noise Analysis are established.As an example the harmonic oscillator is treated. The approach perfectly reproduces the right physics. I.e. , solu...
Structure in phase space associated with spiral and bar density waves in an N-body galactic disk
bar density waves N-body galactic disk
2011/1/11
An N-body simulation of a Galactic disk is used to study the stellar phase space distribution or velocity distributions in different local neighborhoods. Pattern speeds identified in Fourier spectrogr...
The determination of the two-body density functional from its one-body density is achieved for Moshinsky's harmonium model, using a phase-space formulation, thereby resolving its phase dilemma. The c...
Forty-five years after the point de d\'epart [1] of density functional theory, its applications in chemistry and the study of electronic structures keep steadily growing. However, the precise form of...
Static isolated horizons: SU(2) invariant phase space, quantization, and black hole entropy
Static isolated horizons invariant phase space quantization black hole entropy
2010/12/20
We study the classical field theoretical formulation of static generic isolated horizons in a man-ifestly SU(2) invariant formulation. We show that the usual classical description requires revision in...
