We adopt L1 distance as Eve’s distinguishability in secret key generation from a common random number without communication. Under this secrecy criterion, using the Rényi entropy of order 1 + s for s ∈ [0, 1], we derive a new upper bound of Eve’s distinguishability under the application of the universal2 hash function. It is also shown that this bound gives the tight exponential decreasing rate...

In this paper, we show that in order to obtain the Tsallis entropy rate for stochastic processes, we can use the limit of conditional entropy, as it was done for the case of Shannon and Renyi entropy rates. Using that we can obtain Tsallis entropy rate for stationary Gaussian processes. Finally, we derive the relation between Renyi, Shannon and Tsallis entropy rates for stationary Gaussian proc...

In the Letter [1] (also [2]) there is a claim that the generalised second law of thermodynamics (entropy increase) for black holes provides some limits on the rate of variation of the fundamental constants of nature (electric charge e, speed of light c, etc.). We have come to a different conclusion. The results in [1, 2] are based on assumption that mass of a black hole does not change without ...

BACKGROUND Different analytical concepts were introduced to quantify the changes of the electroencephalogram. The Datex-Ohmeda S/5 Entropy Module (Datex-Ohmeda Division, Instrumentarium Corp., Helsinki, Finland) was the first commercial monitor based on the entropy generating two indices, the state entropy (SE) and the response entropy (RE). The aim of the current study was to compare the accur...

AND LATTICE VECTOR QUANTIZATION Peter Monta and Shiufun Cheung Advanced Television and Signal Processing Group Research Laboratory of Electronics Massachusetts Institute of Technology Cambridge, MA ABSTRACT We describe a perceptual audio coder that employs nonuniform hierarchical lterbanks and entropy-coded lattice vector quantization. The nonuniform lterbanks present a good match to critical-b...

According to the thermodynamical analogy in black hole physics, the entropy of a black hole in the Einstein theory of gravity equals S BH = A H /(4l 2 P), where A H is the area of a black hole surface and l P = (¯ hG/c 3) 1/2 is the Planck length [1, 2]. In black hole physics the Bekenstein-Hawking entropy S BH plays essentially the same role an in the usual thermodynamics. In particular it all...

The S = 1/2 Heisenberg antiferromagnet in the ladder geometry is studied as a model for the spin degrees of freedom of SrCu2O3. The susceptibility and the spin echo decay rate are calculated using a quantum Monte Carlo technique, and the spin-lattice relaxation rate is obtained by maximum entropy analytic continuation of imaginary time correlation functions. All calculated quantities are in rea...

life table parameters of the beet armyworm, spodoptera exigua (hã¼bner), on four sugar beet cultivars (renger, fd0005, dorothea and shirin) were studied in laboratory at 27 â± 1â°c, 60 â± 5% rh and a photoperiod of 16l: 8d hours. the larvae successfully developed on all cultivars. the shortest and longest total developmental time were recorded on fd0005 and renger, respectively. the development...

Using Gaussian 03, software the thermodynamic functions such as Gibbs free energy, G, Enthalpy, H, and Entropy, S, of Alanine and Valine amino acids were theoretically studied at different solvents. First, the Density Functional Theory (B3LYP) level with 3-21G, 6-31G and 6-31+G basis sets were employed to optimization of isolated Alanine and Valine amino acids in the gas phase. Moreover, Vib...
