Does Scrambling Equal Chaos?

Image Scrambling Algorithm Based on Chaos Theory and Sorting Transformation

This paper proposed a novel image scrambling scheme based on chaos theory and the sorting transformation. The new algorithm calculates the permuting address codes by sorting the chaotic sequence, not like common method by quantizing the chaotic sequence. Therefore, the new scheme does not require knowing the probability density function of the chaotic orbits in advance, thus not only facilitati...

Fitness does not equal competence.

Does NP not equal P?

The paper is made rediculously irrelevant in light of realization that NP is anything a DTM can solve in time 2^p(|n|). One theorem found on one page taking up about 1 inch in exactly one text. The author therefore no longer supports the nonsense it purports.

Commentary: Ovarian function does not equal fertility does not equal babies.

In the debate about preserving fertility for patients treated with chemotherapy, more is known about inducing gonadal toxicity than is known about avoiding gonadal toxicity. Controversy over how best to advise patients facing a medical decision will commonly occur when inadequate data are available on which to base a sound opinion. The debate becomes passionate when emotionally charged issues s...

What Does Quantum Chaos Mean?

We discuss how the concept of the quantum action can be used to characterize quantum chaos. As an example we study quantum mechanics of the inverse square potential in order to test some questions related to quantum action. Quantum chaos is discussed for the 2-D hamiltonian system of harmonic oscillators with anharmonic coupling. AMS (MOS) Subject Classification: 81Q50, 37N20
